IEEE 338-1975

This document provides design and operational criteria for the performance of periodic testing of nuclear power generating station Class IE power and protection systems. The scope of testing covered consists of functional tests, checks, calibration verification, and time response measurements. Criteria are also provided for determining system operational availability, status, and necessary documentation; and for establishing test intervals, shutdown test procedures, and test procedures during operation. Routine preventative maintenance is not covered by this document. The criteria herein define in greater detail the periodic testing requirements of IEEE Std 279-1971 and IEEE Std 308-1974.



Revision Standard - Superseded. The two standards, IEEE Std 279-1971 (ANSI N42.7-1972), Criteria for Protection Systems for Nuclear Power Generating Stations, and IEEE Std 308-1974, Standard Criteria for Class IE Power Systems for Nuclear Power Generating Stations, establish minimum requirements for the Class IE power and protection systems for nuclear reactors producing steam for electric power generation. These requirements include, but are not limited to, the capability for testing the Class IE power and protection systems. To develop tests and establish test procedures, an expansion and interpretation of the test capabilities specified in IEEE Std 279-1971 and IEEE Std 308-1974 are necessary.
