Assessment of Class 1E pressure transmitter response when subjected to harsh environment screening tests
An experimental investigation into the performance of Class 1E electronic pressure transmitters exposed to environments within and beyond the design basis has been conducted. Emphasis was placed on determining the instruments' failure and degradation modes in separate and simultaneous environmental exposures. Five unaged ITT Barton Model 763 pressure transmitters were tested; each transmitter was exposed to a unique environment. The environments were (1) simulated Loss of Coolant Accident (LOCA) steam/chemical spray conditions alone, (2) temperature alone, (3) radiation alone, (4) simultaneous radiation and LOCA temperature (no steam) conditions, and (5) simultaneous radiation and simulated LOCA steam/chemical spray conditions. 23 refs., 33 figs., 8 tabs.
