NEWPORT, Mich., Jan. 24 /PRNewswire/ — Detroit Edison plant operators shut down the Fermi 2 reactor about 4:20 p.m. today after discovering that cooling water was leaking into the containment structure, a steel and concrete structure that surrounds the steel reactor vessel. Plant operators have preliminarily determined the leakage to be from non-radioactive cooling water.
There is no indication of a radioactive release. Reactor coolant water is being maintained at normal levels and plant safety systems are functioning normally. The leak rate is approximately 50 gallons per minute.
Plant personnel are managing plant systems and plant status. It is expected that workers will be able to enter the area of the plant to locate the source of the leak early Tuesday. Once the source is identified, repair plans will be developed.
The Fermi 2 Nuclear Power Plant is a 1,140-megawatt boiling water reactor owned and operated by Detroit Edison, an electric utility serving more than 2.1 million customers in Southeastern Michigan.That’s a lot of water, but the containment structure is capable of holding hundreds of thousands of gallons of liquid.
