Valve Issues Shut Down Nukes

Faulty valves shut down two nuclear reactors in separate incidents last week.

One reactor in Pennsylvania shut down after workers found a leaky water valve. The Nuclear Regulatory Commission (NRC) said workers found the leak during a startup of Unit 2 at PPL’s Susquehanna nuclear facility near Berwick. The reactor had been offline for maintenance work on its turbines.

PPL said Thursday they turned off the reactor so they could fix the valve. Unit 1 remains at full power.

NRC spokesman Neil Sheehan said inspectors will monitor repairs at the plant, which is 95 miles northwest of Philadelphia.

Meanwhile, Dominion Virginia Power shut down one of the two reactors at its Surry County power plant last week after they detected a valve problem of their own.

Operators at the plant made the decision to power down Unit 2 about 8:30 p.m. Wednesday after discovering a leak in a pressurizer spray valve, said NRC spokesman Joey Ledford.

“It’s not a safety-related valve,” Ledford said. “There are no safety concerns.” Ledford said technicians for Richmond-based Dominion Virginia Power were continuing repairs Thursday.

Unit 1 at Surry, along the James River some 45 miles southeast of Richmond, continued operating at full power.
