In the event of a loss-of-coolant-accident in the reactor to be used to power nuclear ships, it can be postulated that sufficiently high concentrations of H2 and O2 might develop that a resulting explosion would produce overpressures that exceed the containment design. If a LOCA occurred and the H2 concentration reached the explosive limit, an inerting gas could be discharged into the containment to suppress any possible explosion. This report describes several aspects of a study that was conducted to evaluate the feasibility of employing Halon 1301 in an explosion suppression system for a maritime nuclear reactor. The results of the study support the concept of using Halon 1301 for containment protection. The work presented represents an extension of an earlier program (NTIS order no. PB-262 180). Instrumentation to monitor the chemical composition of a containment vessel atmosphere was evaluated; a study of the radiolytic decomposition of Halon 1301 in water was performed, and a computer code to calculate the Halon requirement of a containment is presented.
