This standard describes the criteria for the application and testing of combustion turbine-generator units as Class 1E standby power supplies in nuclear power generating stations. Figure 1 shows the boundaries of systems and equipment included in the scope of this standard. Site testing is covered in Clause 7, and the boundaries for site testing are given in 1.1.2. The purpose of this standard is to provide the principal design criteria, design features, testing, and qualification requirements for the individual combustion turbine-generator units that enable them to meet their functional requirements as a part of the standby power supply under the conditions produced by the design basis events cataloged in the Plant Safety Analysis. New IEEE Standard - Active. The criteria for the application and testing of combustion turbine-generator units as Class 1E standby power supplies in nuclear power generating stations are described in this standard.
