SASSYS validation with the EBR-II (Experimental Breeder Reactor II) shutdown heat removal tests
- Argonne National Laboratory, IL (USA)
SASSYS-1 is a coupled neutronic and thermal-hydraulic code developed for the analysis of transients in liquid-metal-cooled reactors (LMRs). The code is especially suited for evaluating off-normal reactor transients - protected design-basis accidents and unprotected anticipated transients without scram. Because SASSYS is heavily used in support of the Integral Fast Reactor concept and of innovative LMR designs, such as PRISM, a strong validation base for the code must exist. Part of the validation process for SASSYS is analysis of experiments performed on operating reactors, such as the metal-fueled Experimental Breeder Reactor II (EBR-II). During the course of a series of historic whole-plant experiments, EBR-II illustrated key safety features of metal-fueled LMRs. These experiments, the shutdown heat removal tests (SHRTs), culminated in unprotected loss of flow and loss of heat sink transients from full power and flow. Analysis of these and earlier SHRT experiments constitutes a vital part of SASSYS validation, because it facilitates scrutiny of specific SASSYS models and of integrated code capability.
