CFR600冷停堆工况下主系统热量平衡分析
|
摘要
反应堆主热传输系统需要考虑系统散热的影响,根据散热情况设置保温。压水堆电厂在冷停堆工况下只需要维持在较低的温度下,而钠冷快堆以液态金属钠作为冷却剂,其热传输性能远高于水,且其温度必须维持在一定温度以上不能使钠凝固。本文通过分析CFR600冷停堆工况下主系统的热源和散热情况,建立主系统热平衡分析模型,编制计算程序,为后续进行热平衡计算、为CFR600维持稳定运行工况提供技术参考。
The reactor cooling system needs to consider the influence of the heat dissipation and set the insulation.The pressurized water reactor power plant only needs to be maintained at a lower temperature under the cold shutdown condition. But sodium cooled fast reactor uses liquid metal sodium as the coolant, and its heat transfer performance is much higher than water, and its temperature must be maintained at a higher temperature. This paper analyzes the heat source and heat dissipation of the reactor cooling system under the CFR600 cold shutdown condition, and establishes the heat balance analysis model and writes calculation program to provide a technical reference for heat balance calculation and reactor operation.
