研究堆外电网断电试验

Experiments on External Power Grid Failure of Research Reactor

研究堆在电气系统的设计中,针对全厂断电设计基准事故采取了相应的处理措施。研究堆在额定功率运行期间进行了外电网断电试验,用以验证研究堆应急电力和备用电力系统的功能。结果表明在发生外电网断电的设计基准事故时,应急电力和备用电力系统所具有的电气控制和供电功能,可以满足应急停堆、厂房隔离、堆芯冷却、余热排出、剂量监测、控制保护、事故通风的动力要求。

The special process is adopted for the design basis accident of the plant power failure in the design of a research reactor. The external power grid failure test is carried out in the course of the research reactor rated power operation in order to verify the emergency and standby power supply systems. The results of the experiments show that the electrical control and the power can satisfy the requirements of the emergency shutdown, the building isolation, the core cooling, the residual removal, the close monitoring, the control and protection and the emergency ventilation.
