摘要

国胜核电站1号机组目前处于退役过渡阶段，堆芯内仍有乏燃料残留。达到TAF(活性燃料顶部)水位的时间和达到600/800°C包层温度的时间是安全性分析中的关键参数，这些参数影响电站有多少时间来处理瞬态。为此，为了研究停运过渡阶段电站停电(SBO)和失冷剂事故(LOCA)瞬态的水位和包层温度，利用TRACE程序建立了国胜核电站的分析模型。为了评价乏燃料衰变热对水位和包层温度的影响，本研究还进行了衰变热的敏感性分析。

Using TRACE to establish the analysis model of Kuosheng nuclear power plant for decommissioning transition phase

Abstract The Unit 1 of Kuosheng nuclear power plant is in the decommissioning transition phase and still has spent fuel in the core of reactor now. The time to reach the TAF (top of active fuel) for water level and reach 600/800 °C for cladding temperature are the key parameters in the safety analysis, these affect that the plant has how much time to handle transients. Therefore, to study the water level and cladding temperature for station blackout (SBO) and loss of coolant accident (LOCA) transients in the decommissioning transition phase, the analysis model of Kuosheng nuclear power plant was established by using TRACE code. To evaluate the effect of the decay heat of spent fuel on the water level and cladding temperature, the sensitivity analysis of decay heat was also performed in this study.
