A loss-of-coolant-accident in a water-cooled nuclear reactor could result in the accumulation of hydrogen and oxygen gases in the containment vessel, ignition of which might produce explosion pressures that exceed the containment design. Protection against such a hazard can be provided by an inerting system which utilizes Halon 1301 (CF3Br). This inerting gas would be stored in the liquified state and injected only if needed. A development study is reported in which the quantity of Halon required for inerting has been measured, and several envisioned problems investigated. A sub-scale system has been fabricated and used to simulate operation of an actual system under post-MOCA conditions. The testing, together with a system analysis, indicates that the 1301 inerting concept is very suitable for containment application. (Stoehr)
