摘要

毯式系统是核聚变发电的关键要素，其任务是生产氚和有效消散托卡马克产生的高热通量。韩国正在开发氦冷却陶瓷反射器（HCCR）毯式系统，它是韩国毯式系统中最先进的设计。本文介绍了 HCCR 毯子的 LOOP（场外功率损失）事故分析结果。失电事故是核聚变系统中的假定事件之一。这一事件可能由外部电网的常见故障或现场的电气故障引起。本次安全分析的目的是评估事故发生后 90 秒内启动额外电源对系统温度的影响，并评估与毯式系统热交换器相连的 CCWS（组件冷却水系统）中的滞留冷却剂可带走的热负荷。

Loss of power accident analysis for the HCCR blanket

The blanket system is a crucial element in nuclear fusion power generation, tasked with tritium production and the efficient dissipation of the high thermal flux from the tokamak. Korea is in the process of developing the Helium Cooled Ceramic Reflector (HCCR) blanket, which stands as the forefront design among the nation's blanket systems. This paper presents accident analysis results of LOOP (Loss Of Offsite Power) accident for the HCCR blanket. Loss of power accident is one of the postulated events in the nuclear fusion system. This event may be caused by common failure of the external electrical grids or electrical faults in the site. The objective of this safety analysis is to assess the impact of the activation of an additional power supply within 90 seconds after an accident on the system temperature, and to evaluate the heat load that can be removed by the stagnated coolant in the CCWS (Component Cooling Water System) connected to the heat exchanger of the blanket system.
