Early February Restart Planned for V.C. Summer Nuke

LCG, Jan. 10, 2001--South Carolina Electric & Gas Co. said yesterday that repair and testing of a faulty weld in a pipe in the reactor coolant system at its V.C. Summer Nuclear Station are progressing well, and the plant should return to service in late January or early February.

The 1,000 megawatt facility has been shut down since last October 7 when a small leak was discovered during a routine refueling outage. The small leak was in a weld in a big pipe 30 inches across and the pipe is a primary cooling system conduit. It would take a while to fix.

"We initially thought we would be able to put the nuclear plant back in service in early January, butthe repair work has been very time consuming and we want to make sure there are no questionsabout the integrity of the new weld," said Steve Byrne, SCE&G vice president for nuclear operations.

Summer workers cut out a 12-inch section of the pipe, six inches on each side of the weld, and are now welding a new piece of pipe in its place. That means two difficult welds, and they are now nearing completion.

SCE&G has met with the Nuclear Regulatory Commission three times as the repairs have progressed and will meet once more a week from tomorrow. Weld repairs and all associatedtesting should be completed by mid-January with restart of the plant currently scheduled for the endof January or the first week of February.
