Equipment qualification methodology research: tests of pressure switches
Pressure switches, two each of five different models from two manufacturers, were tested in baseline evaluation tests typical of IEEE-323 (1974) suggested profiles as part of the NRC-sponsored Equipment Qualification Methodology Research Test Program (A-1355). The tests incorporated generic seismic and loss-of-coolant accident (LOCA) environments to assess the functional capabilities of unaged equipment. During the baseline evaluation tests, the seismic environment did not affect the functionality of the pressure switches, but the LOCA physical damage in four of five models tested. As a result, eight other switches of the same make and model as those used in the baseline evaluation tests were tested in a follow-up test. In the follow-up test (a discrete-step pressure ramp LOCA environment) erratic functional behavior or complete failure was observed in all the equipment early in the test.
