Equipment qualification methodology research: tests of RTDs
Ten resistance temperature detectors (RTDs), from three manufacturers, were subjected to an abbreviated loss-of-coolant accident (LOCA) environment (saturated steam and chemical spray) simulation test as part of the NRC-sponsored Equipment Qualification Methodology Research Test Program (A-1355). The test was a screening test on unaged specimens that lasted about 24 hours and was of short duration to isolate any obvious problem areas. The LOCA environment caused functional failures and some physical damage in four of the RTDs tested. One RTD failed early in the test, two others of the same type produced erroneous temperature readings 7.5 hours into the test. Post-test investigations revealed that water leakage into the head areas of the three affected RTDs (as well as one other of the same model) may have contributed to the anomolous behavior.
