The NUE triggered an alert to TEMA and other agencies… Unit 2 is fueled but is non-operational. The hot well is where the steam from power generation ends up after being condensed back into water.
WTVC, Mar 9, 2016: TVA spokesman Scott Brooks says the fire broke out at 3:45 a.m. in one of the pump motors, one that received an operating license back in October.
