Monitoring of LWR component cooling water systems

摘要

As part of the Nuclear Plant Aging Research program, the monitoring methods used for component cooling water (CCW) systems in pressurized water reactors (PWRs) were reviewed and evaluated in terms of their effectiveness at detecting various aging mechanisms. A survey of PWRs was performed to determine what practices are currently used. Monitoring methods for three of the major components in the CCW system were correlated with the aging mechanisms they are able to detect, and generic tables of practices were developed. These tables can be used by utilities to strengthen their monitoring program once specific aging concerns have been identified. 1 ref., 2 figs., 5 tabs.
