Validation of RRS Emulator Against Pickering B Setback Event

Abstract

This study compares the coupled RFSP IST/RRS Emulator response with a reactor setback at Pickering NGSB Unit 5. The RRS Emulator was adapted to model the behavior of the Pickering B RRS in the low power regime, where a log power signal is used. Good agreement between the station measurements and the simulation results has been achieved. The station measurements for the average zone level, power error and the control absorber insertion are well predicted by the *CERBERUS/RRS Emulator simulation.
