Only four of 99 domestic reactors currently offline headed into holiday weekend

With United States citizens preparing to celebrate Christmas and Hanukkah, only four of the nation’s 99 active commercial reactors were listed as generating zero power on Friday, Dec. 23.

Most of the domestic nuclear units were listed at or near 100% power with the onset of winter on Dec. 21.

According to data reported to the Nuclear Regulatory Commission (NRC), the following nuclear reactors were not generating any power early Dec. 23:

The Tennessee Valley Authority (TVA) Sequoyah 1 in Tennessee (refueling); American Electric Power (NYSE:AEP) D.C. Cook 2 in Michigan (refueling); the Energy Northwest Columbia plant in Washington state (unplanned); and the Entergy (NYSE:ETR) Grand Gulf plant in Mississippi (repairs) were all listed at zero power.

Winter started this week and most reactors conclude planned refueling and maintenance outages in either the spring or fall. There are now 99 operating nuclear power units in the United States following the retirement of the Omaha Public Power District (OPPD) Fort Calhoun plant in Nebraska. Operations ceased there on Oct. 24.
