Seismic operability demonstration testing of the Westinghouse ISD 7300 Series process instrumentation bistables. [PWR]

The report documents the results of the multiple frequency, biaxial seismic testing of the Westinghouse Instrument Systems Division's--7300 Series Process Instrumentation Bistables. This test program established and demonstrated the operability of the 7300 Series bistable trip cards by submitting the equipment to SSE (Safe Shutdown Earthquake) seismic tests corresponding to a high seismic area, preceded by multiple OBE (Operating Basis Earthquake) seismic tests. The test results presented in the report show there were no electrical malfunctions or mechanical failures that could lead to an unsafe condition in the plant.
