Diesel powered electricity generation cooling

Also, many operators commonly generate electrical power as a primary function via gas turbine or diesel engines, and then as a secondary function use heat extracted from the cooling jackets and flue gases to generate steam in a WH boiler or a HR boiler. 

To minimize damage due to power outage, the Celanese Corporation in their plant at Newark, N.J., instituted a policy of always generating half its own power. Merck Company installed additional auxiliary steam power to insure constant refrigeration for its biochemicals at its West Point, Pa., plant. At Allied Chemical s phenol plant in Frankfort, Pa., electric devices on air compressors and pumps were replaced by steam-operated controls, and diesel generators were installed to maintain cooling water circulation. 19... 

Electrical building - houses the two non-safety-related standby diesel generators and their associated auxiliary equipment, and the solid-state adjustable speed drive units powering the feedwater pump motors and others powering the Reactor Water Cleanup/Shutdown Cooling System pumps. 

The earthquake forced the reactors into automatic shutdown, but it also destroyed all six external power supply sources. As designed, emergency diesel generators in the turbine halls kicked on to supply critical electrical power to the reactor cooling... 

The power supplies to the passive containment cooling system valve room unit heaters are provided by the plant ac electrical system and the onsite standby diesel generators. In the event of a loss of the plant ac electrical system, the passive containment cooling system valve room unit heaters can be transferred to the onsite standby diesel generators by the operator. 

The DPS supplies power to drive the DC pump motors on the PWS to provide recirculation of moderator for core cooling. This system consists of caterpillar diesels, generators, and the electrical distribution system.
