Revision Standard - Active.
The criteria for the application and testing of diesel-generator units as Class 1E standby power supplies in nuclear power generating stations are described in this standard.

This standard defines the criteria for the application and testing of diesel-generator units used 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.
This standard provides the principal design criteria, the design features, testing, and qualification requirements for the individual diesel-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.
