Zirconium Alloy Technology Programme (ZIRAT)

Christian Hellwig
Axpo
Atomic Energy of Canada Limited utilises the ZIRAT and LCC Programmes for the training of new engineers and scientists working on materials performance in nuclear reactors. Apart from learning about generic materials issues pertinent to all nuclear reactor applications AECL’s young scientists and engineers are able to broaden their knowledge of materials performance in other nuclear reactor systems that are different from the CANDU reactors designed and built by AECL. The ZIRAT and LCC Annual Reports provide excellent reference material for our new scientists and engineers and are a valuable resource for scientists like myself who wish to stay current with advances in nuclear materials R&D. The special topic reports that are selected in advance by the Members, are an excellent source of references for those wishing to learn more about particular areas of interest and also provide valuable insights into the underlying subject matter. One recent Special Topic Report in ZIRAT14 summarised published information on in-reactor creep. This very extensive review of the in-reactor creep of zirconium alloys, extending over many decades of published data, is an excellent primer for researchers entering the field. The text and figures are formatted in such a way as to allow a reader to flip through the report and quickly understand the main points of the narrative. The colourful figures and tables are easy to view and add much to the character of the report. I fully expect that AECL will continue to use the forums provided by ZIRAT and LCC to train new staff and as a means of networking with experts in the field of reactor materials engineering.

The name "Rolls-Royce" is known around the world because of its gas turbine technology that is applied to aerospace, marine and energy systems. Some readers may also link the name to Rolls-Royce motor cars, but these have in fact been a completely separate business since the early 1970s. So why has Rolls-Royce been a member of the ZIRAT programme since 2000 (ZIRAT5). It is because nuclear propulsion systems, based on PWR technology, have been a key business for the company since the late 1950s. I believe that Rolls-Royce set a trend by becoming the first noncommercial utility organisation to join ZIRAT: several others have followed since. I was unaware of the programme until I met Ron Adamson at a meeting in late 1999 and we had a conversation about some of the problems relating to maintaining skills and experience in specialist topics like Zr technology. Ron explained what ZIRAT was about and Rolls-Royce became members a few months later. The key factor in the decision was the reputation and expertise of the ZIRAT consultants.

Rolls-Royce has a small team of materials technologists focused on Zr alloys and a vital part of their role is keeping up to date with relevant technology developments. We find ZIRAT a great help and, in a way, it’s like having an extra person in the team. Some of the benefits that we see from ZIRAT membership are: Keeping experienced staff efficiently up-to-speed with external developments. Introducing new staff to Zr technology. Access to a network of consultants with vast experience. Delivery of tailored seminars on topics of specific interest to us. Rapid assistance on technical queries. It is also encouraging to see that, under the direction of ANT International, ZIRAT is continually evolving and improving, for example: even Brian Cox is now using PowerPoint for his presentations! I anticipate Rolls- Royce will be members of ZIRAT for many years to come.

Information on Zirconium Alloy Technology Programme (IZNA)

My company joined the IZNA Program in year 2003 starting with the IZNA1 and IZNA2. Since that year until now, products offered by ANT International have been one of the main sources of information for the training of our new engineers. IZNA Special Topic Reports often serve to our senior engineers as a starting point to face issues that are new for their area of competence. The Annual Reports, not only bring us the opportunity of being updated of all technical news in the nuclear field but, and what is more valuable, to have the news analyzed with a global perspective by the world-known ANT International Expert team. With reference to that, the high knowledge level, the accessibility and the fast answer capacity of the ANT International team are the basis for an efficient consulting service that I have often used. This year, as every year since 2003, Peter Rudling conducted our tailored seminar. More than 30 engineers from nuclear and product engineering, commercial, quality and manufacturing areas attended the seminar that was focused on the current hottest topics as regulatory changes and industry acts to reach 2010 objectives of 0 leakers. This seminar is becoming more and more a discussion forum at high technical level thanks to the content of the materials, the qualification of the speaker and the cooperative spirit of the ENUSA engineers

I attended the training course for the Fuel Design Review Handbook during the Summer of 2012 at Diablo Canyon Nuclear Power Plant. As a Safety Analysis Engineer in the process of cross training into Core Design, this handbook is a must have. It covers all of the critical aspects of nuclear fuel design and does an incredible job of comparing the different design variations used all over the globe. But the most useful part of the Fuel Design Review Handbook is all of the recommended parameters that are to be considered during fuel audits and in the core design process. They cover, in detail, what an audit should focus on, procedural guidance, audit structure and timing and all of the details in the various fuel design and fabrication process at the end of each section. Cladding, pellets, spacer grids, materials, etc are also covered and explained in detail. It is a very impressive and useful document.

As for the training, ANT International brought in the lead writers of the Fuel Design Review Handbook and gave a two day course which detailed out the various sections of the handbook and allowed for input from all of the attendees. The course participants came in from the Fuelco plants (Callaway, Comanche Peak, and Diablo Canyon) and provided enlightening insights to the process of core design, fuel fabrication inspection, fuel failures and other issues that they have encountered over the years. For me, it was a very useful class and I would recommend it for any utility engineers that are currently involved in core design or are considering it. My thanks to all the folks at ANT International that set up this training and especially to Mr. Peter Rudling and Mr. Alfred Strasser for their input and course discussions. As a Core Designer in training, it was a useful course and a reference I will be using a lot.

I performed my first surveillance of our fuel vendor approximately 20 years ago. It was essentially on-the-job training. My mentor had performed audits/surveillances for many years. After about a 10-year hiatus I was thrust back into performing audits, serving as a “technical specialist”. I always felt strange being called a technical specialist on a fuel fabrication audit because my background was not in fabrication, but rather operating. The on-the-job training I had helped. I could pretty much tell if someone was following a procedure but I didn’t have the background to really understand all the activities involved in the fabrication of fuel.

When we began preparing for the INPO Fuel Integrity Review Visit (FIRV) I began to seriously consider seeking out training on the Fuel Fabrication Process. I had met Peter Rudling about 10 years prior and remembered him mentioning their seminar and handbook. I sought out Peter and we put together the plan to acquire the handbook and to put on the seminar. Peter and Al Strasser are experts in this field. Their book is superb and the seminar was outstanding. I liked the seminar because it gave a quick insight into the whole fabrication process in a day and a half. That’s a lot faster than I could get through the book. The book will be a valuable resource to reinforce the seminar with greater insight into all the different processes.

Another reason I liked the seminar is that I was able to get other, newer engineers exposed to the process. I was even able to get some QA auditors involved. We are planning to make this seminar a requirement to serve as a technical specialist for our fuel fabrication surveillances.”

In June of 2008, Peter Rudling and Ron Adamson gave a one-day seminar at GNF's Wilmington, North Carolina site. The Seminar was attended by members of GNF’s Materials Technology and Fuel Reliability team as well as researchers interested in Zircaloy corrosion at GE’s Global Research Center. The seminar covered a range of topics selected from the IZNA7 Annual Report and Special Topical Reports. The seminar agenda was developed with input from GNF to address specific interests of attendees. As one of the STR was on corrosion mechanism, a significant portion of the seminar was devoted to various aspects of Zircaloy corrosion and mechanisms for corrosion failures. Ron and Peter took turns to present materials. The seminar was conducted with an open manner with plenty of audience interaction, a feature that was well appreciated by all attendees.

Overall, the expertise of Peter and Ron and the candid nature of their comments were well appreciated. Comments on the seminar included “It covers many different topics in a short time. May need to extend it as a two-day schedule” and “I think level of expertise brought to seminar is key”.

On May 16–17, The Idaho National Laboratory’s Institute for Nuclear Energy, Science & Technology (INEST) hosted a two-day seminar on fuel performance in light water reactors titled “UO2 & MOX Fuel Performance” led by instructors from ANT International. This seminar was the third in a planned series with previous workshops in 2010 on “Environmentally-Assisted Degradation of Structural Alloys in Light Water Reactors,” and in 2011 on “Zirconium-based Alloys in Nuclear Systems.” The goal of this seminar was to educate a number of INL staff and junior faculty from around the country on the key degradation issues experience by uranium dioxide used for the fuel pellets in nuclear systems. The goal of this seminar was to reinvigorate interest and help kick start a new generation of researchers targeting better fuel performance in nuclear systems. Dr. Todd Allen, the Director of the INEST Fuels and Materials program, organized the seminar, which was presented by Mr. Peter Rudling and Dr. Chuck Patterson of ANT International. The topics covered included Fuel Chemistry, Fission Products, Thermal Properties, Physical Properties, In-Reactor Behavior, Improved Pellet Materials-Additives, and Fuel Behavior during Reactivity Initiated Accidents.

The seminar finished with Mr. Rudling and Dr. Patterson discussing key research challenges for the participants to study. The size of the audience was 45 participants with the room size ultimately limited the final attendance numbers with a waiting list of other interested participants. The audience members, who engaged Mr. Rudling and Dr. Patterson with questions during the presentations, provided extremely positive feedback for the instructors and the material presented.

The participants were quite pleased with the contents of the workshop. “Seminar was very informative and relevant to my work. A lot of information was presented and I plan to go slowly through the slides on my own to better understand some of the topics. “Graphics are very well done – both images and plots. I especially like the diagrams illustrating fuel behaviors. The intro presentations were thorough and good. I liked that the “accident” presentations connected back to the performance presentations.” The Idaho National Laboratory has been extremely pleased with the interactions with ANT and plans to continue these types of workshops. Currently there are a number of collaborative research projects ongoing that were a direct result of the 2010 and 2011 workshops and similar results are anticipated in 2012.

Following the highly successful workshop held at the Idaho National Laboratory in June 2010 titled “Environmentally-Assisted Degradation of Structural Alloys in Light Water Reactors”, ANT International was invited back to Idaho Falls to lead a seminar on “Zirconium-based Alloys in Nuclear Systems”.

This second seminar, also covering a day-and-a-half was held on 10–11 May 2011. The goal of this seminar was to educate a number of INL staff and junior faculty from around the country on the key degradation issues experience by zirconium alloys used primarily as cladding in nuclear systems. And also to reinvigorate interest and help kick start a new generation of researchers targeting better fuel performance in nuclear systems. Dr. Todd Allen, the Scientific Director of the Advanced Test Reactor National Scientific User Facility, organized the seminar, which was presented by Mr. Peter Rudling and Dr. Ron Adamson (Go Badgers) of ANT International.

The topics covered included zirconium alloys used in nuclear systems, radiation damage, mechanical properties, and response to accident conditions, corrosion, dimensional stability, and performance limitations. The seminar finished with Mr. Rudling and Dr. Adamson presenting a list of key research challenges for the group to commence understanding and the participants vowed to get working. “It was a great workshop. The teachers were excellent and very knowledgeable. I appreciated the basic introductions to the reactor concepts and materials issues. I was familiar with many of them but for those that I wasn’t, it was extremely helpful to be given the background. Thank you!” “Excellent intro to the world of Zr, the passion/excitements of speakers were great. I’m happy I was able to attend.” The Idaho National Laboratory is planning a similar seminar in 2012 on uranium dioxide performance in nuclear systems. Participants from the May 2011 seminar have already asked for places in the 2012 course.

ANT International provides with the ZIRAT program a unique product. The expert network does not only cover the subjects like cladding tube and fuel during reactor operation but also during storage thus taking into account e.g. the water chemistry in case of wet storage or the stress and temperature effects of spent fuel during cask loading and dry storage. As the latest research results are compiled in the Annual Reports it is a great way to get informed on what topics are currently under discussion.

The holistic approach, the knowledge of the latest internationally published results in the nuclear field combined with the specialist knowledge and experience of the ZIRAT team members who have worked on the nuclear field for several years is the basis for the conduction of tailored seminars. This approach is beneficial for beginners as well as for those who want to deepen their knowledge on a certain aspect.

Since 2009 onwards Peter Rudling and Friedrich Garzarolli conducted 1-day seminars at GNS which covered processes during dry storage thereby dealing with the mechanical behavior of fuel assemblies, corrosion and hydrogen pickup mechanisms, oxide thickness at discharge burnup and potential failure mechanisms of fuel rods. Providing information on the issue of interest to our organization guarantees the seminar success. Finally, the direct dialogue with the experts is of great importance for the effectiveness of the progress of knowledge. Again, participants from 2011 recommended to continue this series of tailored seminars. The next seminar is scheduled for September 2012.

Fuel Design Review Handbook

Fuel Design Review Handbook (FDRH) is a unique handbook. It contains not only features of various fuel designs but also fuel design fundamentals, design audits and recent topics in nuclear fuel technology. The authors of this handbook have condensed decades of experience in a single volume. I am sure any new engineer who enters the fuel design field will find this handbook very useful. In this regard, it seems quite successful. One specific thing that I would like to mention is the really beautiful and colorful layout of this handbook which also characterizes all ANT deliverables even in the electronic format!

Fuel Fabrication Process Handbook

I began auditing fuel fabrication processes in 1983. I was trained on quality assurance audit techniques, but there were essentially no sources available to learn the intricacies of fuel fabrication. Therefore, I entered the school of ‘learning by experience’ and we all know that ‘experience’ is something you acquire after you need it! Fortunately, I did have a good mentor. It is now 2008. I have acquired twenty-five years of experience and I am now the mentor for our junior engineers. Fortunately for them, we have a great resource available in the Fuel Fabrication Process Handbook. This handbook contains the what, why and how to perform oversight of fuel fabrication processes. It reviews the processing of raw uranium and zirconium, fabrication of components and the production of the completed fuel assembly. The handbook also contains a description of fuel assembly types, qualification programs and quality assurance systems. For example, the pellet fabrication section discusses the preparation of the uranium dioxide powder, and the pressing, sintering, grinding and inspection of the pellet. Each section discusses the process parameters that influence the characteristics and quality of the final product. A recommendation of priority items to be audited is provided at the conclusion of the section.

The authors of this handbook have condensed decades of experience into a single volume. I make sure that any new engineer becomes familiar with the handbook before attempting to audit a fuel fabrication process. Further, I never leave home without it when I am performing an audit. It has become an invaluable reference to ensure that I am auditing the important characteristics of fuel fabrication.

As responsible for the manufacturing follow-up done by Vattenfall Fuel I have been very pleased with the FFPH (Fuel Fabrication Process Handbook) so far, and it is been used actively within our company. It is a very readable textbook for engineers with a basic interest in nuclear fuel. To have it on our computer server gives opportunities for selfstudies. We have to introduce new people to the area of fabrication follow-up; the most experienced people are soon retiring or needed for other tasks. In our competence-training program we use the FFPH as well as teaching by fuel vendors and hands on training by our experienced specialists.

The FFPH has been a valuable tool because it presents the basic background in a systematic and pedagogical manner. The computer interface has been very practical, because it can serve as an online look up dictionary. We have to perform our manufacturing follow-up in a systematic and logical manner. For this reason we have recently made a detailed walkthrough of our process descriptions and instructions. The FFPH turned out to be a good reference tool because it already provides the basics for systematism with its checklist type of approach. The experienced and knowledgeable authors are our assurance for the quality and completeness of the material. Nevertheless we had many and vivid discussions on what and how we should actually follow up in order to convince ourselves of the flawlessness of the final products.

My only problem so far is that the attractive layout and the well balanced text and figure material means that people like to borrow the book from my desk. But I decided to live with that.

Management of BWR Control Rods Report

The MBCR (Management of BWR Control Rods) is, as all reports by ANT International, an excellent handbook that offers a complete overview of all there is to know about control rods in BWR reactors. After a systematic, didactic and enjoyable introduction of the basic concepts, very useful for beginners or forgetful veterans like me, MBCR provides a complete and comprehensive compendium to the current state of the art knowledge in this field. All the topics are presented clearly, from the BWR control rod designs and operation criteria to the rod material sensitization by effect of irradiation. The text also describes in detail the degradation and failure mechanisms and the radiochemical effluents behavior.

MBCR is indispensable for expert engineers responsible for the control rod management so they can make optimum use of the rod in order to reduce the direct replacement and waste disposal costs, while ensuring an efficient and safety plant operation. The high quality of the text is the result of great experience and knowledge of the authors, Dr. Kurt-Åke Magnusson and Mr. Klas Lundgren that have a lifetime of experience in the nuclear materials technology area. This handbook can be read cover to cover for those who seek to understand the BWR control rods in its entirety, and can also be used as a reference source to look up useful facts and information concerning specific areas. Together with the hardcover book a CD with the book in a searchable pdf format is delivered. It is very useful in the e-book reader, and makes the book easy accessible.

In 1994 I started my career, as a research chemist, in the radiochemical laboratory of the NPP Philippsburg, Germany. I moved on to several different positions within the chemistry department and now I am head of this department. As such, I need to know the requirements of chemistry surveillance from the bottom and up. My practical experience, together with my educational background, has made me well prepared for this position. However I was not present when the plant was commissioned and I did not gather the valuable experience of elderly colleagues, who were present at a time when deviations from normal operation required unusual measures. As a chemist of the second nuclear generation in Germany I therefore feel confident to be a member of the LWR Coolant Chemistry, LCC Programme. The long experience of the LCC Expert Team provides useful information for “sunny and cloudy days” of a chemist job! The LCC Annual Report provide a quick overview of the latest developments in the nuclear water chemistry world. The LCC Special Topic Report collect, analyse and summarise issues and facts in depth that are essential for an understanding of the development and state of the art of nuclear chemistry. I am looking forward to be present at the next LCC Meeting!

I started my career at the Commercial Nuclear Fuel Division of Westinghouse Electric Corporation in 1984 as a materials design engineer. During my tenure at Westinghouse, I have worked extensively in the areas of materials development, application and performance evaluation in pressurized water reactors (PWR). My dual educational background in material science and engineering and in chemistry prepared me well for my career. During the past six or seven years I have seen rapid changes to reactor coolant chemistry with zinc injection and elevated lithium operation and have studied the impact of these changes on fuel performance. I have also seen experiences in PWR used to improve fuel performance in boiling water reactors (BWR) and vice versa. For example ultrasonic fuel cleaning was first developed and qualified for PWR application and later on was qualified for BWR application. The BWR experience with the role of sulfates in intergranular stress corrosion cracking of stainless steel components has been used to set limits for sulfates in the PWR spent fuel pool. Thus, it is useful to find in one place both chemistry and materials performance related-experience for PWR, BWR and VVERs. For new engineers and chemists, this could be a very useful training tool. For experts in a given field, knowledge of experience in other related fields facilitates improvements in their own fields. ANT International plays an important role in fulfilling this need in the nuclear industry through the LWR Chemistry and Component integrity, LCC programme.

My background is Chemical Engineering and almost all my professional career I have been linked to Cofrentes Nuclear plant. I participated in the plant’s startup tests, and joined the Chemistry group when the plant started its commercial operation. For more than 16 years I was responsible of Chemistry and Radiochemistry. In 2006 I moved to my present position in the Engineering Support Department. The Iberdrola’s relationship with ANT International goes a long way back. It started with our Fuel Department but quickly extended into areas of fuel failure, water chemistry interaction with fuel, chemistry and materials, control rods evaluation etc. by means of seminars, training courses or specific studies. We were always very satisfied with the results of these activities, as we found a perfect balance between the theoretical knowledge and explanation of the fundamental facts and their practical application. Therefore, when we were offered to participate in the LCC Programme we almost joined it without a doubt. The idea of gathering an important family of veteran experts to transmit their knowledge and experience in the areas where they developed the industry advances, and to provide a follow up of these matters, is simply splendid. After six LCC Programme Memberships we have a very positive balance of our participation. We appreciate very much the yearly updates from the international meetings on materials, corrosion and chemistry. It is a very practical way to be informed about new research and experiences of what has been published. But even more interesting are the Special Topic Reports that are published annually by the LCC experts on different topics. This part of the programme provides a thorough approach of the specific matters, from the theoretical basis, its historical development, the application of the results and the most recent approach and, for some technologies it provides an independent view of advantages and disadvantages. The text and the clear and smart graphics make these Special Topics Reports of special value for training new personnel in these times when the plants are incorporating young engineers.

I've been with Vattenfall for over 30 years were I worked both as technician, supervisor and chemistry manager at the Ringhals site before becoming a senior chemistry specialist and advisor about 10 years ago. I came to Ringhals early in a period of pioneer spirit, which made it possible to make some career with hard work despite only having a technical senior high school as background. In my case, “learning by doing” together with a lot of reading has been a guiding-star in most cases. Ringhals is still the only site in Sweden with PWR:s and with exception of some work in foreign units during OSARTs- and Peer Reviews, I’ve been stuck to the site and the Swedish west-coast most of the time, a beautiful place from spring to autumn, but not very exiting during the windy and rainy winters. My main areas of expertise and interest are PWR primary water chemistry related to radiation built up and fuel performance. Ringhals units have shown low dose-rates and good fuel performance for several years, partly explained by carefully controlled primary water chemistry. Another area of interest for me has been water management with demonstration of new purification technologies and the site lately spent some efforts in developing some new water treatment systems showing good experiences.

Since a few months, I belong to a small department for research and development (R&D) were I’m responsible for the “Chemistry & Radiochemistry” part. However, I will still be dealing with issues related to common chemistry problems and strategies for the site. I’ve known ANT International and some of the experts since a long time and do regularly join the LCC Seminars as well as some of the ZIRAT Seminars. I find those very useful, not only for the presentations but also to meet the speakers and other colleagues for some fruitful discussions. Both the annual reports and specific technical reports provide good overviews of many actual topics and I’m sure that the LCC Programme, which has been continuously expanded, will continue to draw more chemists to the programme. Together with the different handbooks, ANT International provides excellent material for education, this supports the very important transfer of knowledge in times when alternation of generation becomes a problem in many nuclear power plants.

The Idaho National Laboratory hosted a 1.5-day long seminar titled “Environmentally-Assisted Degradation of Structural Alloys in Light Water Reactors” on June 8th and 9th, 2010. Dr. Todd Allen, the Scientific Director of the Advanced Test Reactor National Scientific User Facility, organized the seminar. The goal of this seminar was to educate a number of junior INL staff and junior faculty from around the country on the key environmental degradation issues facing both pressurized water reactors and boiling water reactors. With the number of researchers in the U.S. studying issues relevant to light water reactors dwindling, the goal of this seminar was to reinvigorate interest and help kick start a new generation of researchers targeting better material performance in nuclear systems.

The instructors for the seminar, supplied by ANT International, were Peter Ford, Peter Scott, and Pierre Combrade who covered an introduction to stress corrosion cracking, the general phenomenology and mechanistic hypotheses of stress corrosion cracking, stress corrosion cracking of stainless steels in low temperature environments, stress corrosion cracking in boiling water reactors, corrosion fatigue issues, stress corrosion cracking in pressurized water reactors, and irradiation effects on stress corrosion cracking. The participants had backgrounds in material science, mechanical engineering, and water chemistry but in general, did not have any extensive knowledge of environmental effects in nuclear systems. Across the board, the attendees were extremely enthusiastic about the seminar. One stated “A rare and exceptional workshop. These two days bought together true deep expertise, representing over 100 years of industry experience, and an enthusiastic group of young scientists eager to bring state of the art tools to bear on cutting edge problems. Such a workshop is enormously more efficient than simply letting university researchers try to ferret out the real issues and problems on their own. These two days may have saved months of work on the part of the participants. Workshops of this type and caliber should be the standard for how new research areas are launched and promoted.”

The Idaho National Laboratory is planning a similar seminar in 2011 on zirconium alloy performance in nuclear systems.

On December 17th, 2008 Peter Ford gave a very well prepared one-day lecture on corrosion phenomena that lead to the degradation of structural materials in water-cooled nuclear reactors. In the audience physicists, chemists and materials scientists of Borssele NPP were represented. The presentation is based on the ANT report of the same title. The report had been purchased by us, but no one had found time yet to carefully read it.

The lecture by Peter was an excellent introduction to the report and it helps us in using the information from the report in an efficient way. The presentation started with the introduction of the thermodynamics that is necessary to understand the mechanism of the various corrosion phenomena. Subsequently, a wide range of different types of corrosion in the various important construction materials of the NPP has been discussed. The mechanism that leads to degradation of the material have been elaborated and discussed with the audience.

Peter has such a broad knowledge on the subject that he is an excellent teacher both for them who already have a lot of knowledge in the field themselves and for those for whom the subject of the lecture is quite new. The lecture brought us what we hoped it would bring and it made the Structural Material Degradation Report much more valuable for us.

On April 29th Dr. Peter Ford gave a one-day seminar on “Degradation of Structural Materials in Water Cooled Nuclear Reactors” to staff members from Iberdrola, Iberdrola Ingenieria and Nuclenor, involved in material issues at primarily Cofrentes and Garoña NPPs but also at the other Spanish NPPs. The seminar was mostly based on the Degradation Report of the same title authored by Dr. Peter Ford and published by ANT International. The audience ranged from young staff to senior utility management who was comparatively new to the subject and need a “quick introduction” or searched for a broader and deeper knowledge of the material degradation beyond what they might face on a daily basis.

Dr. Ford gave an excellent seminar which included a lot of interaction with the audience. His main messages were: 1) A proactive management of material issues is possible based on the knowledge of the controlling factors for each relevant degradation mode and 2) The industry is doing a huge effort in identifying the existing knowledge gaps to be able to predict the degradation and, if possible, mitigate it. Despite the necessarily short seminar the audience received an overview of the topics covered in the report and may later consult the report for more in depth information.

LWR Chemistry and Component Integrity Programme (LCC)

Atomic Energy of Canada Limited utilises the ZIRAT and LCC Programmes for the training of new engineers and scientists working on materials performance in nuclear reactors. Apart from learning about generic materials issues pertinent to all nuclear reactor applications AECL’s young scientists and engineers are able to broaden their knowledge of materials performance in other nuclear reactor systems that are different from the CANDU reactors designed and built by AECL. The ZIRAT and LCC Annual Reports provide excellent reference material for our new scientists and engineers and are a valuable resource for scientists like myself who wish to stay current with advances in nuclear materials R&D. The special topic reports that are selected in advance by the Members, are an excellent source of references for those wishing to learn more about particular areas of interest and also provide valuable insights into the underlying subject matter. One recent Special Topic Report in ZIRAT14 summarised published information on in-reactor creep. This very extensive review of the in-reactor creep of zirconium alloys, extending over many decades of published data, is an excellent primer for researchers entering the field. The text and figures are formatted in such a way as to allow a reader to flip through the report and quickly understand the main points of the narrative. The colourful figures and tables are easy to view and add much to the character of the report. I fully expect that AECL will continue to use the forums provided by ZIRAT and LCC to train new staff and as a means of networking with experts in the field of reactor materials engineering.

In 1994 I started my career, as a research chemist, in the radiochemical laboratory of the NPP Philippsburg, Germany. I moved on to several different positions within the chemistry department and now I am head of this department. As such, I need to know the requirements of chemistry surveillance from the bottom and up. My practical experience, together with my educational background, has made me well prepared for this position. However I was not present when the plant was commissioned and I did not gather the valuable experience of elderly colleagues, who were present at a time when deviations from normal operation required unusual measures. As a chemist of the second nuclear generation in Germany I therefore feel confident to be a member of the LWR Coolant Chemistry, LCC Programme. The long experience of the LCC Expert Team provides useful information for “sunny and cloudy days” of a chemist job! The LCC Annual Report provide a quick overview of the latest developments in the nuclear water chemistry world. The LCC Special Topic Report collect, analyse and summarise issues and facts in depth that are essential for an understanding of the development and state of the art of nuclear chemistry. I am looking forward to be present at the next LCC Meeting!

I started my career at the Commercial Nuclear Fuel Division of Westinghouse Electric Corporation in 1984 as a materials design engineer. During my tenure at Westinghouse, I have worked extensively in the areas of materials development, application and performance evaluation in pressurized water reactors (PWR). My dual educational background in material science and engineering and in chemistry prepared me well for my career. During the past six or seven years I have seen rapid changes to reactor coolant chemistry with zinc injection and elevated lithium operation and have studied the impact of these changes on fuel performance. I have also seen experiences in PWR used to improve fuel performance in boiling water reactors (BWR) and vice versa. For example ultrasonic fuel cleaning was first developed and qualified for PWR application and later on was qualified for BWR application. The BWR experience with the role of sulfates in intergranular stress corrosion cracking of stainless steel components has been used to set limits for sulfates in the PWR spent fuel pool. Thus, it is useful to find in one place both chemistry and materials performance related-experience for PWR, BWR and VVERs. For new engineers and chemists, this could be a very useful training tool. For experts in a given field, knowledge of experience in other related fields facilitates improvements in their own fields. ANT International plays an important role in fulfilling this need in the nuclear industry through the LWR Chemistry and Component integrity, LCC programme.

My background is Chemical Engineering and almost all my professional career I have been linked to Cofrentes Nuclear plant. I participated in the plant’s startup tests, and joined the Chemistry group when the plant started its commercial operation. For more than 16 years I was responsible of Chemistry and Radiochemistry. In 2006 I moved to my present position in the Engineering Support Department. The Iberdrola’s relationship with ANT International goes a long way back. It started with our Fuel Department but quickly extended into areas of fuel failure, water chemistry interaction with fuel, chemistry and materials, control rods evaluation etc. by means of seminars, training courses or specific studies. We were always very satisfied with the results of these activities, as we found a perfect balance between the theoretical knowledge and explanation of the fundamental facts and their practical application. Therefore, when we were offered to participate in the LCC Programme we almost joined it without a doubt. The idea of gathering an important family of veteran experts to transmit their knowledge and experience in the areas where they developed the industry advances, and to provide a follow up of these matters, is simply splendid. After six LCC Programme Memberships we have a very positive balance of our participation. We appreciate very much the yearly updates from the international meetings on materials, corrosion and chemistry. It is a very practical way to be informed about new research and experiences of what has been published. But even more interesting are the Special Topic Reports that are published annually by the LCC experts on different topics. This part of the programme provides a thorough approach of the specific matters, from the theoretical basis, its historical development, the application of the results and the most recent approach and, for some technologies it provides an independent view of advantages and disadvantages. The text and the clear and smart graphics make these Special Topics Reports of special value for training new personnel in these times when the plants are incorporating young engineers.

I've been with Vattenfall for over 30 years were I worked both as technician, supervisor and chemistry manager at the Ringhals site before becoming a senior chemistry specialist and advisor about 10 years ago. I came to Ringhals early in a period of pioneer spirit, which made it possible to make some career with hard work despite only having a technical senior high school as background. In my case, “learning by doing” together with a lot of reading has been a guiding-star in most cases. Ringhals is still the only site in Sweden with PWR:s and with exception of some work in foreign units during OSARTs- and Peer Reviews, I’ve been stuck to the site and the Swedish west-coast most of the time, a beautiful place from spring to autumn, but not very exiting during the windy and rainy winters. My main areas of expertise and interest are PWR primary water chemistry related to radiation built up and fuel performance. Ringhals units have shown low dose-rates and good fuel performance for several years, partly explained by carefully controlled primary water chemistry. Another area of interest for me has been water management with demonstration of new purification technologies and the site lately spent some efforts in developing some new water treatment systems showing good experiences.

Since a few months, I belong to a small department for research and development (R&D) were I’m responsible for the “Chemistry & Radiochemistry” part. However, I will still be dealing with issues related to common chemistry problems and strategies for the site. I’ve known ANT International and some of the experts since a long time and do regularly join the LCC Seminars as well as some of the ZIRAT Seminars. I find those very useful, not only for the presentations but also to meet the speakers and other colleagues for some fruitful discussions. Both the annual reports and specific technical reports provide good overviews of many actual topics and I’m sure that the LCC Programme, which has been continuously expanded, will continue to draw more chemists to the programme. Together with the different handbooks, ANT International provides excellent material for education, this supports the very important transfer of knowledge in times when alternation of generation becomes a problem in many nuclear power plants.

Tailored Seminars

I studied chemistry in Ulm, Germany dealing with the special field of synthesis of Au clusters and methane hydrates and supra molecular chemistry in the Department of polymer chemistry/homogeneous catalysis. Since March 2006 I am the referee for Power Plant Chemistry in the Gundremmingen Nuclear Power Station. In this function I became aware - through colleagues from Isar NPP - of the activities of ANT International. As ANT International is specialised in providing expert training and knowledge in the areas of nuclear fuel, reactor materials, and water chemistry I became interested in the one-day-seminars in particular. Based on the information provided by ANT International, we organized an in-house training on BWR reactor water chemistry. The agenda of this seminar was co-ordinated between ANT International and KGG and finally about 50 persons attended the seminar. During the seminar ANT International provided an overview on the background of reactor water chemistry practices in the US and Europe as well as about the interaction between materials and chemistry. Due to the experience with ANT International I am convinced that LCC and in particular the one-day seminars are very meaningful products. Moreover, the content of the training is very useful for our daily business

Nuclear Power Plant Krško (Slovenia) has in the last few years hired several new employees who are trained to work directly or indirectly on the chemistry of water media. We used our membership in the LCC Program run by ANT International to implement a two-day tailored course, which was held in February 2011 at the Plant’s Training Facility in Krško. The lectures were attended by app. 20 colleagues from various organizational units: Chemistry, Fuel, Radiological Protection, Production, QA and Maintenance (ISI Group). Two experts, Dr. Francis Nordmann and Dr. Hartmut Venz covered numerous theoretical and practical areas from chemistry of water media of primary and secondary side, corrosion and other degradation mechanisms which influence the chemical program, conditions of materials, review of practice and experiences from other plants, and chemistry activities during startups and shutdowns.

Our younger colleagues, as well as everyone else present, were delighted with the high level of expertise and professionalism provided by the two conducting lecturers. Without a doubt it will present great support for their work, further qualifications and careers. Nuclear Power Plant Krško strongly recommends such training to other plants, especially the ones which are dealing with a new generation of nuclear workers.
