Susquehanna Nuclear said Tuesday that Unit 2 at the Susquehanna nuclear power plant had been reconnected to the grid after a four-day manual shut down that took the reactor off line on Friday.
Unit 1 at the plant continues to operate “safely and at full power,” the company said. Unit 2, however, was shut down May 13, due to a fault in one of the unit's 480-volt electrical distribution centers, according to a company statement.
The plant is designed through redundant systems to account for the potential for these types of faults, the company noted. Technicians at the plant “responded in accordance with their training to place the unit in the condition to allow investigation and repair,” the statement said.
The Susquehanna plant, located seven miles north of Berwick, Pa., (70 miles northeast of Harrisburg), is comprised of two General Electric Type 4 boiling water reactors that are licensed to operate through 2042 and 2044, respectively. They were originally licensed for operations in 1982 and 1984, respectively.
The plant is jointly owned by Susquehanna Nuclear LLC and Allegheny Electric Cooperative Inc. It is operated by Susquehanna Nuclear.
