The Versatile Test Reactor (VTR) is a fast spectrum test reactor currently being developed in the United States under the direction of the US Department of Energy (USDOE), Office of Nuclear Energy. The mission of the VTR is to enable accelerated testing of advanced reactor fuels and materials required for advanced reactor technologies. The conceptual design of the 300 MWth sodium-cooled metallic-fueled pool-type fast reactor has been led by US National Laboratories in collaboration with General Electric-Hitachi and Bechtel National Inc.
Current VTR efforts include the development, design, and analysis of a sodium fire protection system (SFPS) strategy for the reactor facility. This paper summarizes the evolution of SFPSs in the U.S. from previous test reactors such as the Experimental Breeder Reactor II (EBR-II) and the Fast Flux Test Facility (FFTF) to larger proposed commercial reactors designs such as the Clinch River Breeder Reactor (CRBR), PRISM, the Sodium Advanced Fast Reactor (SAFR), and the Large-Scale Prototype Breeder (LSPB). Additionally, the software tools (NACOM and SOFIRE-II) utilized to analyze sodium fire scenarios for the VTR are described along with a summary of current software verification and validation (V&V) efforts. Finally, the design philosophy for the VTR SFPS strategy is presented, which is based on SPFS design evolution and insights from preliminary sodium fire analyses. The work reported in this summary is the result of studies supporting a VTR conceptual design, cost, and schedule estimate for DOE-NE to make a decision on procurement. As such, it is preliminary.
