SIMULATION OF THE PRESSURE SET-POINT CHANGE TRANSIENT WITH THE KUOSHENG PLANT ANALYZER

The purpose of this paper is to simulate the pressure set-point change transient with the Kuosheng plant analyzer. The Kuosheng plant analyz er was developed for the Kuosheng nuclear power station based on the b oiling water reactor plant analyzer of the Brookhaven National Laborat ory and the Chinshan plant analyzer of the Taiwan Power Co. First, the pressure control system (PCS) model was verified on a stand-alone bas is, with the sensed dome pressure test signal as the input variable. T hen, a transient induced by a step change in the pressure set-point wa s simulated with the Kuosheng plant analyzer and compared with the tes t data. The predicted results of the main system variables showed good agreement with the test data-within 8% of the maximum relative deviat ion. In addition, the PCS performance of the Kuosheng nuclear power st ation was analyzed. (C) 1997 Elsevier Science S.A.
