Operators of at a Bay City nuclear power station have restarted the Unit 1 reactor, which is currently at about 5% capacity as of Wednesday afternoon, said Victor Dricks, senior public affairs officer with the U.S. Nuclear Regulatory Commission.
The Unit 1 reactor reconnected to the electric grid at 9:07 p.m. Wednesday, said Vicki Rowland, Internal Communications lead at STP Nuclear Operating Company in an email. The reactor is "ascending to 100% power" as of Thursday morning.
The most recent outage of a South Texas Nuclear Project reactor was on May 1, 2016.
About 5:30 a.m. Monday, workers at the South Texas Nuclear Project shutdown the Unit 1 reactor because of freezing water, said Matagorda County Judge Nate McDonald.
The reactor has a 1,350-megawatt generation capacity and was expected to come back online at about 10 p.m. Tuesday. The full generating capacity cannot be reached immediately as it needs to “coast back up” to a normal generating level while workers monitor the reactor.
Workers manually shutoff the reactor Monday out of precaution for “safety before profit.”
The Unit 2 reactor remains online at full generating capacity.
