Progress Energy Inc. has shut its 937 megawatt (MW) unit 2 at Brunswick nuclear power station in North Carolina on early April 23, 2009 from 4% on early April 22, 2009, the U.S. Nuclear Regulatory Commission said. The unit started to exit a refueling outage earlier this week. The electricity traders said they did not know if the unit actually exited the refuel. The nuclear reactors generally exit outages when they reach 15% to 20% power.

The unit shut for the refueling on about February 27, 2009.

The work on turbine controls and plant upgrades extended the outage a bit, a spokeswoman for the plant said in earlier week.

At the time of plant’s shut down, the electricity traders estimated that it would be back in around six weeks.

The unit last shut in the spring of 2007 and is on a 24-month refueling cycle.

The 1,875 MW Brunswick station is situated in Southport in Brunswick county, around 160 miles south of Raleigh. The station has two units, 938 MW unit 1 and the 937 MW unit 2, which have entered service in 1977 and 1975.

The unit 1 at the station continued to operates at full power.
