Description

IEC 61502 Ed. 1.0 b – Nuclear power plants – Pressurized water reactors – Vibration monitoring of internal structures

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.
