Nuclear units running hard early in 2017

The domestic nuclear power fleet in the United States is running hard in the early days of 2017 with the Entergy (NYSE:ETR) Grand Gulf plant in Mississippi the only reactor listed at zero power early Jan. 5, according to Nuclear Regulatory Commission (NRC) data.

Three of four nuclear units that had been offline Dec. 3 have now returned to at least partial service with the latest being the Tennessee Valley Authority (TVA) Sequoyah 1 in Tennessee, which was listed at 29% early Jan. 5.

The American Electric Power (NYSE:AEP) D.C. Cook 2 in Michigan and the Energy Northwest Columbia plant in Washington state had returned to commercial operation in recent days.

TVA completed the scheduled refueling and maintenance outage at Sequoyah 1 on Wednesday, Jan. 4. Operators are returning the unit to its full capacity, generating enough power for 650,000 homes.

In addition to replacing 72 of the unit’s 193 fuel assemblies, detailed inspections of the reactor vessel were conducted to confirm all components continued to meet or exceed all design requirements and were fully able of performing their safety functions, TVA said in a Jan. 5 news release.
