Development of a RCS Coolant Leak Detection System for Reactor Safety Enhancement

A 0.007 gpm real-time small-and-unidentified leak detection system has been developed. The standard environment test procedures for nuclear power plants were applied to confirm the plant applicability of the developed system. As a result of the minimum leak detection performance test, 0.007 gpm leak detection was demonstrated. If this system is applied to a pressurized light water system, it is po…
