Abstract
This is a technical state of the art report for the prevention methodology of the Interfacing System LOCA (ISLOCA) resulted from the rupture of the Shutdown Cooling System outside the containment which is designed at low pressure and directly connected to the Reactor Coolant System in Pressurized Water Reactor. The ISLOCA had occurred in the U.S.A. (three reported event, Vermont Yankee-12/12/75, Browns Ferry 1-8/14/84, and Pilgrim-9/29/83), and the U.S. NRC reviewed the event in early 1980s. The U.S. NRC`s review results revealed that the probability of ISLOCA is considerably higher than expected. As a result, the U.S. NRC began to have a great concerns for the ISLOCA. The nuclear power plant suppliers in U.S.A. have also tried to improve the system to prevent the ISLOCA. While the U.S. NRC did not express any official position or issue the design requirements for the ISLOCA as of 1992, the nuclear power plant suppliers present the conceptual design features without detail design analysis. The ongoing project of Ulchin Nuclear Power Plant Units 3 and 4 (UCN 3/4) design in Korea requires prevention of the ISLOCA, however, there are some difficulties in implementing the design requirements in the aspects of system configuration and component
