Diesel Back-up Generators and Nuclear Plant Safety Recent events in Japan have raised interest in the role of diesel electric generators in nuclear power plants. Diesel-powered generators play a critical role in maintaining continuity of power for critical functions at nuclear power plant facilities.

The evolution of longer-life nuclear power plants has a significant impact on the design of emergency diesel generator (EDG) used for station blackout (SBO) support. Existing plants could be looking for 70 to 90 years of life from their power supply.

For an EDG/SBO to operate for 70 to 90 years and still remain reliable, many variables must be considered. June RD, Aging Management for Nuclear Power Plants.

Aging management activities shall be implemented proactively throughout the lifecycle of an NPP or SCC (e.g., in design, fabrication and construction, commissioning, operating, and decommissioning).
