Fermi 2 nuclear plant shuts down after excess hydrogen found in water
DTE Energy shuts down Frenchtown Township nuclear power plant due to excess hydrogen gas in system
DTE Energy Co. says it shut down its Fermi 2 nuclear power plant because of an excess of hydrogen gas in a cooling system for the main electrical generator.
DTE spokesman Guy Cerullo tells the Monroe Evening News that the plant shut down about 9:30 a.m. Wednesday.
Cerullo says operators saw that water in part of the cooling system for the generator contained higher than normal amounts of hydrogen.
The generator is on the non-nuclear side of the plant and has two separate cooling systems for its different sections. One uses water and the other hydrogen.
An increase in hydrogen gas in the water-cooled system decreases its efficiency.
The 1,100 megawatt reactor is next to Lake Erie in Monroe County's Frenchtown Township, near Monroe.
