Defines the requirements for instrumentation to detect leakage from reactor coolant systems of light water nuclear reactors. Methods of leak detection are described, and characteristics of different methods of detection and of differentiating between allowable and abnormal leakages are given. The object is to define therequirements for leakage detection data, for arranging it in a logical manner, and for displaying information to enable the operator to take appropriate action. A secondary objective is to standardize criteria, methods and procedures for assuring the design and operational adequacy of the detection systems.
