Browns Ferry hit by major storms, World Nuclear News, April 29, 2011:
[...] The three boiling water reactors at TVA’s Browns Ferry nuclear power plant in Alabama shut down automatically with cooling systems powered by “a combination of offsite transmission and on-site diesel generators.” However, the shutdown was notified as an ‘unusual event’ to the Nuclear Regulatory Commission “when the normal and alternate power supplies for essential equipment were unavailable for more than 15 minutes.” TVA stressed that “safety systems performed well.”
The plant shut down on 27 April at 4.36 pm and units 2 and 3 achieved cold shutdown at 2.43 am and 5.45 am on 28 April respectively. TVA said that unit 1 was was being cooled and the priority now was to get that reactor into cold shutdown as well.
One 161 kV line is available to Browns Ferry, as are all the plant’s eight diesel generators. One of these was out of service for maintenance when the storms hit, but work was completed quickly and the generator put back to work. [...]
