We have developed PAR for BWR that equiped a catalyst to recombine and treat oxygen and hydrogen generated in the BWR containment vessel(PCV) during an accident. we investigated the basic property of PAR foucused on the condition such as the the ratio of hydrogen and oxygen, temperature and pressure in PCV,
