Lessons Learned From Internal Flood PSAs In Korea

Abstract

Risk due to internal flooding has been one of the major concerns for the design and approaches for flood protection systems, active and passive, can be considered. The approaches to flood protection design are different for each plant design, and they are due to a flooding event is highly dependent on the flood design. The major design characteristics are 1) the location of systems that utilize sea water and their impact to other sump which can transfer and accommodate flood water to prevent a significant flooding event. To identify and compare the effectiveness and potential vulnerability of various plant designs, such as existing Korean PWR plants, CANDU type PHWR plants, and Korean Standard Nuclear Plants.
