ABWR Power Tests Simulation by using a Dual RELAP5 Nuclear Power Plant Simulation Platform
Lungmen nuclear power plant is the first advanced boiling water reactor (ABWR) plant in Taiwan. According to the most up-to-date schedule, Lungmen Plant will begin its power tests in later 2010. The tests contain (1) loss of feedwater heater test, (2) one feedwater pump trip test, (3) one reactor internal pump trip test, (4) three reactor internal pumps trip test, (5) loss of offsite power and turbine/ generator trip test, (6) turbine trip test, (7) load rejection test, (8) fast load winddown test, and (9) reactor full isolation test. The acceptable values of the plant major parameters in all test criteria of each plant power test have been provided by the plant vendor’s analysis results. Thus, the verification of the correctness of the vendor results is important. A dual RELAP5 advanced Lungmen Plant specific simulation platform (ALPS) had been used to simulate the plant power tests. ALPS is developed based on two independent RELAP5 modules and all plant systems simulation models are synchronized on a PC-based commercial simulation platform, namely 3KeyMaster. One of two RELAP5 modules is for the reactor system modeling and the other is for the balance of plant system modeling. The plant major control systems and the emergency core cooling system all are simulated in great detail with the built-in modeling tools of 3KeyMaster. ALPS calculation results had been compared with the plant vendor’s preliminary power tests analysis results. And the comparison results had been delivered to the plant vendee for references. Some typical power tests simulation and comparison results have been demonstrated in this article. They are (1) one feedwater pump trip test, (2) one reactor internal pump trip test, (3) load rejection test, and (4) reactor full isolation test.
