Nuclear Standby Power

Nuclear Standby Power

As a trusted supplier of emergency standby power to the nuclear power generation industry, Fairbanks Morse Engine designs, manufactures and tests our medium-speed diesel engine generator sets to comply with all Nuclear Regulatory Commission (NRC) requirements. Fairbanks Morse emergency diesel generator (EDG) sets supply electrical power to safely shut down the nuclear reactor in the event of a loss of normal offsite power, coolant accident or other operational anomaly. Typically installed in groups of two or more as a back-up system, the EDGs are designed to meet the same stringent requirements as all of the other safety systems inside the plant.

Today there are more than 100 Fairbanks Morse diesel engine generators standing by to ramp up in seconds and supply emergency power to nuclear power plants across the U.S. We back our emergency power diesel generator sets for the nuclear industry with world-class service, factory-direct engineering services, diesel engine inspection programs and quality Fairbanks Morse Engine OEM parts.



Why choose medium speed diesel engines?Medium speed diesel engines used in electrical generators operate between 500 to 1000 rpm, and are optimized to provide rapid response to load changes. Medium-speed diesel engines provide much greater durability and reliability, and less downtime compared to higher speed engines — all essential requirements for nuclear service.

How many Fairbanks Morse engine generator sets are in nuclear service?At present, there are more than 100 Fairbanks Morse engine generator sets in service in nuclear power plants in the Americas.

Why is a proven track record especially important in the nuclear industry?For obvious reasons, quality, reliability and durability are mandatory requirements for the nuclear power industry’s safety-related systems. Decades ago, Fairbanks Morse Engine earned its reputation as a supplier of dependable power to the U.S. Navy’s emerging nuclear fleet, so it was logical for the developers of the first commercial reactors to turn to Fairbanks Morse, as well, for their critical emergency back-up power needs. As construction of nuclear plants expanded, Fairbanks Morse remained the industry leading supplier of diesel generator sets. At present, more than 60% of owners and operators of nuclear power plants in the United States depend on Fairbanks Morse engines.

What about engineering services?Factory-direct engineering services are available to meet the needs of nuclear utilities throughout the life of the power plant.
