One of two plant reactors remains offline

November 10, 2012

The reactor unit that was shut down just over a week ago at the Comanche Peak nuclear plant south of Granbury in Somervell County remained offline as of press time, according to a representative of Luminant Generation Co., which operates the plant. Meanwhile, the representative said early Friday that power has been temporarilty reduced on the second unit at the site because of a tube leak on an auxiliary condenser on the non-nuclear side of the plant.

Luminant Corporate Communications Manager Ashley Barrie said Friday of the power reduction in Unit No. 2, “We’ll be back up to 100 percent once this routine maintenance has been completed,”

High temperatures detected in a reactor coolant pump motor bearing prompted reactor Unit No. 1 to be manually shut down at 1:42 a.m. on Nov. 2 by plant operators for maintenance.

“The unit will return to service once work is complete,” Barrie said of Unit No. 1. She said she could not provide an estimate for how long Unit No. 1 is expected remain offline, nor explain what the down time could mean to Luminant customers.

Early this week, Barrie said that plant officials were still looking into the cause of the Unit No. 1 issue.

The incident was posted as a “non-emergency” incident on the website of the Nuclear Regulatory Commission (NRC).

The NRC’s initial report on Unit No. 1 stated that reactor conditions were “stable” and “all safety systems functioned as designed.”
