The Susquehanna nuclear power plant operated by Talen Energy (NYSE:TLN) in Luzerne County, Pennsylvania made a non-emergency notification to the Nuclear Regulatory Commission (NRC) on Wednesday, June 8, 2016 about a problem at Unit 1.
As was previously reported, Susquehanna Unit 1 was shut down on June 6 for planned maintenance to identify and repair a small leak inside the containment structure that completely surrounds the reactor. During the investigation, Susquehanna staff identified and reported additional leakage from an instrumentation connection to the reactor vessel.
The leak rate is currently measured at two drops per minute.
Unit 1 remains shut down and the condition is not a safety risk for plant workers or the public, the company said in a June 8 news release. “We have established a dedicated team of nuclear professionals to further evaluate the situation and develop a plan to safely complete repairs, said Robert Franssen, plant general manager.
“We will continue to work with the NRC, industry experts and our equipment vendors to understand the issue, evaluate our repair options, complete the necessary work and safely return the unit to service,” Franssen said.
Susquehanna Unit 2 continues to operate at full rated power.
The Susquehanna plant, located about seven miles north of Berwick, is jointly owned by Talen’s Susquehanna Nuclear, and Allegheny Electric Cooperative and is operated by Susquehanna Nuclear.
Talen announced June 1 that it has entered into a definitive merger agreement with affiliates of Riverstone Holdings LLC, a private investment firm that’s already a stakeholder in Talen. The agreement provides for a “go-shop” period, during which Talen Energy – with the assistance of its legal and financial advisors – may actively solicit other offers.
