Nonintrusive methods for monitoring the operational readiness of solenoid-operated valves
Solenoid-operated valves (SOVs) are being studied at Oak Ridge National Laboratory as part of the USNRC Nuclear Plant Aging Research (NPAR) Program. The primary objective of the study is to identify, evaluate, and recommend methods for inspection, surveillance, monitoring, and maintenance of SOVs that can ensure their operational readiness--that is, their ability to perform required safety functions under all anticipated operating conditions. An earlier (Phase I) study described SOV failure modes and causes and identified measurable parameters that might be used to monitor the various degradations that lead to functional failure. The present (Phase II) study focuses on devising and then demonstrating the effectiveness of techniques and/or equipment with which to measure the previously identified performance parameters (or others) and thus detect and trend the progress of any degradation that may be occurring. 1 ref., 3 figs.
