Analysis of Chinshan-1 power test data with the BNL plant analyzer

The Brookhaven National Laboratory (BNL) plant analyzer, also called the high-speed interactive plant analyzer (HIPA), was developed to reduce the time and cost associated with nuclear power plant transient simulation. The BNL analyzer proved to be quite accurate for the analysis of boiling water reactor (BWR) designs and compared well with the results of TRAC-B01, RAMONA-3B, and RELAP-5 calculations. Modification such as feedwater pump control system, SRV logics, input parameter, and form loss coefficient were made to HIPA's BWR/4 models to accommodate the BWR/4 plant-specific design features of Chinshan-1. This paper presents comparisons of HIPA prediction to Chinshan-1 data for two important power tests.
