Scana Corp. shut down its nuclear power plant in the Midlands Monday, immediately after discovering a small steam leak.

The rupture was in a "non-nuclear" portion of the V.C. Summer plant in Jenkinsville and presented no danger to workers or nearby residents, Scana officials said.

The Nuclear Regulatory Commission, a federal body that keeps inspectors at the facility full-time, said it was too early tell what caused the leak, and whether the incident raised flags about the facility's condition.

"We're sort of piecing it back together," said Roger Hannah, a regional spokesman for the NRC based in Atlanta. "It's not an immediate safety issue, because they took the plant offline. But we want to make sure that we understand the situation completely before we make any assessment of whether it was a significant safety issue or not."

A plant worker discovered the leak shortly after midnight Sunday and Scana initiated a rapid shutdown of the facility shortly thereafter.

Officials are unsure how long it will take to repair the leak, but they estimate the plant will be up and running in a few days, according to company spokeswoman Mary Green Brush.

Small leaks and ruptures are becoming more common at U.S. nuclear plants, most of which are approaching the end of an initial 40-year period during which they are permitted to operate.

Santee Cooper owns one-third of the V.C. Summer plant. Scana is in charge of operating the facility. The plant generates about 20 percent of Scana's power on average.

The Jenkinsville plant has had several such incidents in recent years, including a radioactive coolant leak in March and a potentially more dangerous leak in 2000.
