Transformer fire forces TVA to shut down Unit 2 reactor indefinitely TVA probes cause of switchyard fire at Watts Bar Tuesday night. Times Free Press August 31st, 2016 by Dave Flessner
The blaze in one of the main bank transformers connected to the new Unit 2 reactor triggered notice of “an unusual event” — the lowest of four emergency classifications for problems at a nuclear power plant. Although the fire did not affect any nuclear or generation equipment in either the reactor or turbine buildings at Watts Bar, it did damage a transformer and required TVA to shut down its Unit 2 reactor indefinitely, TVA spokesman Jim Hopson said today. ….
When the fire erupted, the reactor had to be shut down and the unit will remain idle until a new transformer is installed and the cause of the fire is determined. http://www.timesfreepress.com/news/local/story/2016/aug/31/transformer-fire-nuclear-plant-triggers-emergency-notice/384326/
