Talen taking Susquehanna Unit 1 offline for maintenance issue

Talen Energy (NYSE:TLN) operators have taken the Unit 1 reactor at the Susquehanna nuclear plant in Luzerne County, Pennsylvania offline in order to address a maintenance problem.

Operators started to power down the unit late Sunday, June 5, and disconnected it from the regional transmission grid early June 6.

Talen said the unit is being shut down to address a small water leak inside the Unit 1 containment structure. 

“Our nuclear professionals have spent the past week developing various contingencies to ensure the safest and most efficient approach to repairing the leak,” said Jon Franke, site vice president. “Although this is not causing a challenge at this time, it is our priority to find and fix this prior to full summer operations.”

Talen said it is premature to provide a specific timeline for returning Unit 1 to service “As has always been the case, Team Susquehanna’s primary focus is safety, so that we can then deliver reliable, zero-carbon energy to our customers,” said Franke. 

Susquehanna Unit 2 continues to operate safely at full rated power.

The Susquehanna plant, located about seven miles north of Berwick, is jointly owned by Susquehanna Nuclear, LLC, 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.

On the Talen nuclear front, Susquehanna Unit 2 had gone offline unexpectedly in May.
