Roughly 10,000 MW of nuclear capacity offline for fall outages

Records from the Nuclear Regulatory Commission (NRC) and other sources show that more than 10,000 MW of nuclear generating capacity is offline as the industry enters the traditional fall shoulder season.

The majority of the outages involve regularly scheduled refueling and maintenance issues although there is a smattering of unplanned shutdowns being addressed. Here’s a rundown:

**Exelon (NYSE:EXC) Braidwood 1 in Illinois went offline Sept. 8. It has a generating capacity of roughly 1,200 MW.

**Peach Bottom 3, the 1,100-MW nuclear unit in New Jersey, went offline Sept. 9. It is undergoing a power uprate during the outage.

**PPL (NYSE:PPL) Susquehanna 2 in Pennsylvania went offline Sept. 15 after declaring an “unusual event” with the NRC in reaction to a water leak and ongoing turbine issues. The nuclear reactor can generate about 1,300 MW following a recent power uprate.

**Duke Energy (NYSE:DUK) Catawba 2 in South Carolina went offline Sept. 14. Catawba is a 1,100-MW-plus unit.

Duke’s Robinson 2 nuclear unit in South Carolina is also offline for a scheduled outage. It is a 725-MW unit. It reportedly went offline Sept. 14.

Southern (NYSE:SO) Hatch 2 in Georgia went offline Sept 15 to do maintenance on a valve in the steam supply system. As of Sept. 20 the repairs had been made and the unit was about to be returned to service, a Southern spokesperson said. The unit is rated at 925 MW.

Dominion (NYSE:D) North Anna 1 in Virginia left service Sept. 7. It has a generating capacity of roughly 980 MW. It is doing some Fukushima-related safety upgrades.

DTE Energy (NYSE:DTE) Fermi 2 is a roughly 1,100 MW nuclear unit near Detroit. The utility took the nuclear unit offline Sept. 9 to address a feed-water pump that failed in June 2012. The plant has been operating at only 68% since then, a DTE spokesperson said Sept. 20.

Omaha Public Power District (OPPD) Fort Calhoun nuclear station in Nebraska continues to be offline. The nuclear unit shut in April 2011 for a refueling outage. The Missouri River flooding of 2011 interrupted that outage work last summer due to the historic river levels. It is a roughly 500-MW nuclear unit.

Wolf Creek Nuclear Operating has the Wolf Creek nuclear plant in Kansas offline following an unplanned outage Sept. 11 that involved a problem with air conditioning equipment. Wolf Creek has a generating capacity of roughly 1,285 MW.
