Heavy water reactor double-chamber MCCI process analysis method and calculation device

A heavy water reactor double-chamber MCCI process analysis method comprises the following steps: establishing a heavy water reactor nuclear power plant model, and dividing nodes; an accident initial condition is provided, the multi-stage process of the heavy water reactor MCCI is simulated, when one accident stage reaches a preset exit condition, simulation of the next accident stage is started, and the simulation result of the previous accident stage determines the initial condition of simulation of the next accident stage; and judging the effectiveness of the containment of the heavy water reactor nuclear power plant according to a simulation result of the MCCI process. According to the method, the double-chamber MCCI process of the heavy water reactor can be effectively simulated and analyzed, and the structural design and safety management of the heavy water reactor can be guided. The invention further provides a computing device. 一种重水堆双腔室MCCI过程分析方法，包括以下步骤：建立重水堆核电厂模型，并划分节点；提供事故初始条件，模拟重水堆MCCI的多阶段过程，其中当一个事故
