NRC approves more power output for McGuire Nuclear Power Plant

The Nuclear Regulatory Commission (NRC) has approved a request by Duke Energy Carolinas to increase the power generation capacity of McGuire Nuclear Station Units 1 and 2 by 1.7 percent each.

The NRC staff determined that Duke Energy could safely increase the nuclear reactors’ power output primarily through more accurate means of measuring feedwater flow. As part of its evaluation, NRC staff reviewed the company’s analysis showing the plant’s design can accommodate the increased power level.

The NRC’s safety evaluation of the power plant‘s proposed power increase focused on several areas, including the nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, fire protection, operations and training, testing and technical specification changes.

Duke intends to implement Unit 2’s increase during its spring 2014 refueling outage, and Unit 1’s increase during its fall 2014 outage.
