Abstract:

India has an ambitious nuclear energy programme including the development of a closed fuel cycle Fast Breeder Reactor systems. The Fast Breeder Test Reactor (FBTR) at The Indira Gandhi Centre for Atomic Research, Kalpakkam, India has operated successfully for the last 25 years with a unique mixed carbide fuel (U0.3Pu0.7)C as its driver fuel. The fuel has been taken to very high burnup levels of 155 GWd/t. The 20 % cold worked SS316 material used as structural material has seen a cumulative neutron damage in excess of 80dpa. The 500 MWe Prototype Fast Breeder Reactor (PFBR) which is in advanced stage of construction at Kalpakkam, India, will use mixed oxide (MOX) fuel and D9 as structural material with a target burnup of 100 GWd/t. Systematic performance evaluation of the fuel and structural materials through Post Irradiation Examination (PIE) at different burnups has enabled understanding the behavior of plutonium rich carbide fuel well beyond the initial burnup limit of 50 GWd/t. A brief description of the PIE facilities established will be presented. Post irradiation examinations have also been carried out on Prototype Fast Breeder Rector (PFBR) MOX fuel irradiated in FBTR after attaining a burnup of 112 GWd/t . This presentation will discuss the results of various examinations carried out for understanding the performance fast reactor fuels and structural materials irradiated in FBTR. Results of post irradiation mechanical property evaluation and structure property correlations done including the miniature specimen test techniques will be also discussed. The materials development programme for future FBRs envisaged in India like improved D9, ODS and ferritic-martensitic steels will be highlighted briefly along with the description of the irradiation test facilities in FBTR.

Stability, Asymmetry and Risk

Abstract:

As the U.S. considers potential paths towards nuclear arms reduction, key considerations are asymmetry (the state of the US nuclear stockpile deterrent and variations in international nuclear capabilities) and risk (degree of transparency/trust and ability to verify commitments). As stockpile numbers go down, each weapon takes on increased importance and stability of deterrence will be essential. Technically we can achieve reduced risk levels in our stockpile and the ability to verify compliance, if we plan and prepare. Increased transparency and dialogue could enable better understanding of the risks and help direct future negotiations in an environment of increased confidence.

About the Speaker:

BRUCE GOODWIN is the Associate Director at Large for National Security Policy and Research and the Director of the Center for Global Security Research (CGSR). In these roles he is responsible for the LLNL Nation Security Office and CGSR. He previously was the Principal Associate Director for Weapons and Complex Integration at Lawrence Livermore from 2001 until 2013. He has been a key player in the success of the nuclear weapons program since 1981, first at Los Alamos National Laboratory and then at LLNL since 1985. He led the process to certify LLNL nuclear weapons and was responsible for establishing priorities, developing strategies and designing and maintaining LLNL’s nuclear weapons; for the past 12 years he has been responsible for leading the Stockpile Stewardship Program. Goodwin was instrumental in developing the Quantification of Margins and Uncertainties methodology for sustaining the deterrent without nuclear testing. He lead the development of innovative reuse methods to extend stockpile lifetimes and streamline manufacturing. He championed cutting edge high performance computing for national security and competitiveness. He won the Department of Energy E.O. Lawrence Award for innovative weapons science for demonstrating that plutonium behaves in a fundamentally different way than previously thought – now the basis for understanding weapons performance. Goodwin received his doctorate and master’s degree in Aerospace Engineering from the University of Illinois, and a bachelor’s degree in Physics from City College of New York. He is a recipient of many awards and the author of numerous technical and policy papers. As one of the world’s leading theoretical experts in plutonium and implosion dynamics, he often presents weapons physics to the community, officials and members of Congress.

NuScale Power: Thinking Small in a Big Way

Abstract:

Although roughly a third of the ~440 commercial nuclear power plants operating world-wide have capacities less than 700 MWe, nearly all new plant designs available on the global market are large, monolithic plants with output capacities in the range of 1000-1700 MWe. The large
capacity and staggering price tag severely limit the number of customers that can reasonably consider purchasing new nuclear plants. Interest in smaller sized nuclear power plants has been growing steadily world-wide and is now emerging rapidly in the United States. NuScale Power is
developing a small modular reactor design that will offer a more affordable and more flexible approach to expanding the use of nuclear energy for a broader range of energy customers. Based on a standardized and highly robust 45 MWe nuclear module, a NuScale plant will be scalable up to 12 modules, each of which are factory fabricated and can be installed in an incremental fashion to maximize affordability and owner flexibility. A brief overview of the NuScale module and plant design will be presented with emphasis on the high level of safety, affordability and flexibility achieved by the modular
design.
