碩士 === 國立清華大學 === 核子工程與科學研究所 === 104 === The objectives of this thesis is to establish a Kuosheng Mark III containment model using CONTAN, which is coupled with Kuosheng Boiling Water Reactor (BWR) model using TRACE. The result of coupled calculation was different to other researches which calculate them separately. The Kuosheng CONTAN analysis model was built up refers to FSAR and other related documents. After the model had been established, the Main Steamline Break (MSLB) transient was simulated and compared to FSAR’s results. After the CONTAN analysis, the model was coupled to Kuosheng TRACE model, and two cases, MSLB, and Feedwater Controller Failure without Bypass (FWCFNB) were used to simulate the transient in containment. Both transients caused the injection of working fluid. However, MSLB transient let the working fluid go into the drywell, and FWCFNB let it go through the SRVs, ended in the suppression pool. The result of MSLB analysis was compared to FSAR and GOTHIC’s analysis, while FWCFNB (NPP part) was compared to FSAR. The trends of the Kuosheng TRACE/CONTAN model’s result were correspond to FSAR and GOTHIC’s, which were approximately the same.
