标准摘要
[中文适用范围]: 本标准适用于根据在容器和容器外部观察到的中子波动来监测压水堆内部结构(堆芯筒、热屏蔽、上、下堆芯支架等)和燃料组件振动行为的系统振动。本标准中描述的监测的主要目的是检测内部结构的退化。初级电路测量可以与内部监测一起考虑,以提供进一步的信息,并使检测初级电路结构支撑的退化成为可能。该标准涵盖了系统特性并给出了监控建议。 [外文原描述]: Applies to systems used for monitoring the vibratory behaviour of the internal structures of pressurized water reactors (core barrel, thermal shield, upper and lower core support, etc.) and fuel assemblies on the basis of neutron fluctuations observed outside the vessel and vessel vibrations. The main objective of monitoring is to detect degradation of internal structures.
英文名称Nuclear power plants - Pressurized water reactors - Vibration monitoring of internal structures
