Testing of nuclear qualified cables and pressure transmitters in simulated hydrogen deflagrations to determine survival margins and sensitivities
In order to evaluate the margins for equipment survival in a hydrogen burn, a series of equipment tests was conducted at Sandia National Laboratories Central Receiver Test Facility. These tests subjected artificially aged and unaged specimens of qualified Brand Rex electrical cable and Barton Model 763 pressure transmitters to heat flux pulses simulating increasingly severe hydrogen burns. The initial base heat flux pulse used in the tests was representative of a hydrogen deflagration in a large dry containment building resulting from a 75% metal-water reaction. Starting with the base pulse, the test specimens were exposed to increasingly severe heat flux pulses until a pulse whose heat flux levels were three times those of the base pulse was reached. Specimen performance was checked during and after exposure to each of the simulated hydrogen burns. 15 refs., 20 figs., 11 tabs.
