All nuclear power plants have backup generators in case the plant stops producing electricity. … This is necessary in case generators fail. They provide power that has a sufficient capacity of emergency equipment, but not enough for normal cooling equipment.
What is the purpose of emergency generator?
Emergency generator means a stationary combustion device, such as a reciprocating internal combustion engine or turbine that serves solely as a secondary source of mechanical or electrical power whenever the primary energy supply is disrupted or discontinued during power outages or natural disasters that are beyond the …
What happened to the diesel generators at the nuclear power plant?
The impact caused an electrical fault that de-energized the in-service transformer between the grid and the unit, triggering a LOOP. One of the two emergency diesel generators was out of service for maintenance. The remaining emergency diesel generator automatically started.
Do power plants use diesel?
Diesel generators are widely used at most Coal, Gas and Oil Fired Power Plants and virtually all Nuclear Power Plants in the United States has an emergency backup power source for the station’s auxiliary needs. … In large Power Plants, there is usually at least one emergency diesel generator set per unit.
