摘要
核电机组环形空间通风系统用于维持环形空间的负压,保证来自内层安全壳内的空气在排放前经过过滤,从而减少放射性物质向环境的释放。认为环形空间通风系统最大调适风险来自自动变频控制系统的调适,应提前梳理影响自动变频控制系统调适的内外部因素,制定相应的管控措施。
The annular space ventilation system of nuclear power units is used to maintain negative pressure in annular space to ensure that air from inner containment is filtered before discharge, in order to reduce the release of radioactive materials to the environment. Points out that the greatest commissioning risk of the annular space ventilation system comes from the commissioning of the automatic frequency conversion control system, internal and external factors affecting the commissioning of automatic frequency conversion control system shall be considered in advance and formulate corresponding control measures.
