本文介绍了利用堆内水回路研究快堆覆盖气体的监测方法,用气水分离器空间模拟快堆覆盖气体空间,用气回路模拟覆盖气体监测回路,监视堆内燃料元件是否发生破损。静电沉降器采用固定电极,没有传动部件,设备简单。它利用放射性惰性裂变气体的固态子代产物的沉降,收集在G-M计数管金属阴极的外表面。设计三种不同结构形 This paper introduces the monitoring method of the fast reactor covering gas by using the water circuit inside the reactor, simulating the space covered by the fast reactor with the gas-water separator space, simulating the cover gas monitoring circuit with the gas circuit, and monitoring whether the fuel components in the reactor are damaged or not. Electrostatic precipitator using a fixed electrode, there is no transmission parts, equipment is simple. It utilizes the settling of solid progeny products of radioactively inert fission gases and collects on the outer surface of the G-M counter tube metal cathode. Design three different shapes
