Description

Multiple spurious operation (MSO) means multiple fire induced circuit faults causing an undesired operation of one or more systems or components. The Nuclear Energy Institute (NEI) published NEI 00-01 as analyses and guidelines for solving these problems of MSO. And this guideline includes MSO scenarios of pressurized water reactor (PWR) and boiling water reactor (BWR). Nuclear operators in U.S. performed analyses on MSO based on the MSO scenarios included in NEI 00-01 and and have done them by applying the same guidelines even in PWR in Korea. MSO scenarios of pressurized heavy water reactor (PHWR) are not included in NEI 00-01 because there are no ones in U.S. and the reasonable scenarios have not been developed until now. This paper developed a MSO scenario which can be applied to PHWR by reviewing the 62 MSO scenarios included in NEI 00-01. The analytical results have found that the applicable scenarios are 7 among 62 ones and additional 3 new scenarios had been developed.
