Operating and Test Experience for the Experimental Breeder Reactor II (EBR-II)

Abstract – This paper describes the contributions of EBR-II to sodium-cooled fast reactor technology. The reliability of the EBR-II system was demonstrated through 30 years of operation and sodium maintenance technology was well established. As an irradiation test facility, Oxide, Metal, Carbide and Nitride fuels were developed. As an operational-safety test facility, the self-protecting response of a metal-fueled reactor to upsets was demonstrated and the benefits to safety were quantified in a PRA. The safety of operation with breached fuel was also demonstrated. As the Integral Fast Reactor (IFR) prototype, non-aqueous reprocessing and recycle of fuel was demonstrated and fuel containing minor actinides was fabricated and irradiated.  Waste forms for geologic storage of waste from fuel reprocessing were developed and qualified. When decommissioned, draining and reaction of the sodium to produce an acceptable form for disposal was accomplished, including passivation of residual sodium. The EBR-II experience and test program has established the viability of sodium-cooled fast reactor power plants.

I. INTRODUCTION

Fast reactors are an important element of a global renaissance of nuclear power because they can use as fuel the waste that thermal reactors produce (primarily long-lived minor actinides). Studies have indicated that approximately 20% of the fleet should be fast reactors to effectively manage this waste. Further, fast reactors can greatly extend the fuel supply (approaching a factor of 100). Extending fuel supply was the promise of fast-reactor development at the dawn of the nuclear age. EBR-I, a fast-reactor, was the first reactor in the world to produce electricity (December of 1951). EBR-II then followed, producing power in 1964 and operating for 30 years as a complete power plant (1,2). The EBR-II test program addressed all of the fundamental issues associated with fuel performance, fuel recycle, sodium technology and reactor safety. Based on this and extensive international experience (3,4), sodium-cooled fast-reactor technology has been shown to be successful.

SUMMARY OF EXPERIENCE

My 34-year career in advanced reactor and fuel-cycle development has led to international recognition in the areas of passive nuclear safety and advanced reactor design.  I am widely published in the technical community.
My technical achievements include developing the approach to reactor safety now considered the standard for advanced nuclear systems, namely design approaches which emphasize passive safety. I was the principal author of the program of Operational Safety Testing at the EBR-II Reactor and was a principle in developing the Integral Fast Reactor Program, the major nuclear R&D program for DOE in the 1980s and 1990s

EDUCATION
Ph.D., Nuclear Engineering, University of Arizona, 1970
