We are developing an in-PCV PAR for BWR that uses a catalyst to recombine and treat oxygen and hydrogen generated in the BWR containment vessel (PCV) during an accident. It was confirmed that the selected catalyst maintained its recombination reaction activity even when the total amount of iodine generated in the assumed accident environment was given.
