Abstract
ABSTRACTPCTran ABWR is a fast-running simulation code for Lungmen nuclear power plant. The code was developed by Micro-Simulation Technology and implemented by Taiwan Power Company (TPC). PCTran can be installed in a PC under Windows operating system and has excellent ability to simulate transients and accidents in a nuclear power plant.In the thesis, we tried to use PCTran ABWR to simulate and compared cases chosen from Preliminary Safety Analysis Report (PSAR). The simulated cases are mainly selected from the chapter 15 in PSAR.This thesis first introduced the important function and features of PCTran. And then, the significant parameters accounted in PSAR are listed. Finally, according to the cases analyzed in PSAR, we simulated these cases by using PCTran ABWR code and compared the results between PSAR and PCTran. The simulating ability and reliability of PCTran ABWR can be evaluated after the comparisonThrough the comparisons between PCTran ABWR and PSAR, we noticed that all results are quite similar. But we need further research for some transient simulation results. For example, we found that we could not fail all feedwater pumps during the simulation. Some logics for signal triggering are not the same as in PSAR. There is also some difficulties manipulating turbine control valve and bypass valve failure at the same time. The neutron flux responses are not quite sensitive as it should be.
