概要
By evaluating the phenomena that hydrogen concentration of outlet gas in the off-gas treatment system at Hamaoka Unit 4 and 5 had increased, it was con cluded that the causes of the phenomena were transformation of support alumina by alteration of manufacturing process of catalysts and the deactivation by catalyst poisoning material. Therefore, the manufacturing process was modified and the poisoning material was identified and removed. Moreover, dev elopments such as catalyzer performance monitoring technology with thermometers have been continued in order to improve the reliability of the system.
