Large-scale hydrogen burn equipment experiments. Final report
Experiments were conducted to examine the ability of selected types of equipment in nuclear plants to operate during and after a hydrogen burn event, such as that which occurred in the TMI-2 accident. Both premixed and continuous injection tests were conducted in a 52-foot diameter sphere at the US DOE Nevada test site. The sphere provided controlled testing in a large-scale volume, but was not a mock-up of any reactor configuration. Twenty-one equipment types and twenty-four cable types were tested. The equipment included pressure transmitters, solenoid valves, a motor operated valve, limit switches, a fan motor, resitance temperature detectors (RTDs), hydrogen igniters, and containment pentrations. All equipment was operated during the experiments, with the exception of the cable samples and penetration leads. Fifteen premixed and continuous injection tests were performed. Measurements were made of equipment operability, equipment temperature, and chamber pressure, temperature, and heat flux. Except for several spurious malfunctions attributed to testing problems, all but a few equipment specimens operated normally during and after all tests. 144 figs., 36 tabs.
