The RELAP5 independent assessment project at Sandia National Laboratories is part of a multi-faceted effort sponsored by the NRC to determine the ability of various system codes to predict the detailed thermal; hydraulic response of LWRs during accident and off-normal conditions. The version used for the FY 1982 assessment project was RELAP5/MOD1/CYCLE14, the latest publicly released version available at the time this project was begun. The RELAP5 code is being assessed at SNLA against test data from various integral and separate effects experimental test facilities. At the request of the NRC contract monitor, the FY 1983 project was expanded to include TRAC-PF1 and RELAP5 plant analyses. A design-basis 200% cold leg break accident for the Sequoyah UHI plant had been analyzed at Sandia for a different NRC project; the analysis began on the TRAC-PD2 code and was completed with the TRAC-PF1 code, using a detailed fine nodalization, particularly in the 3-D vessel.
