Electronic Isolators Used in Safety Systems of U.S. Nuclear Power Plants.

摘要

The report presents results from an evaluation program for electronic isolators used in safety systems of U.S. nuclear power plants. Included are recommendations for test methods that can be used to ensure that isolation devices are being qualified adequately to satisfy IEEE-279 requirements. These recommendations are based on studies made of National Standards; conversations held with utility personnel, Nuclear Steam System Suppliers, Architect Engineers, and the isolator vendor staff; and analysis of actual tests performed on sample isolators.
