Federal regulators are sitting down to answer questions about safety performance at a South Carolina nuclear plant. The U.S. Nuclear Regulatory Commission is holding an open house on Monday to answer questions about the Catawba nuclear power plant in York County owned by Duke Energy Inc.

Federal regulators say a brief power outage and cooling system disruption at a South Carolina nuclear plant last year was a low to moderate safety risk.

The U.S. Nuclear Regulatory Commission has warned the nuclear industry to be careful in its construction oversight after finding problems at the Savannah River Site.
