D.C. Cook Unit 2 receives approval for power uprate

May 6, 2003 — The Nuclear Regulatory Commission has approved a request by the Indiana/Michigan Power Co. to increase the generating capacity of Unit 2 at the D.C. Cook nuclear power plant by 1.5 percent.

The power uprate at the plant, located near Benton Harbor, Michigan, increases the generating capacity of the plant from 1090 to 1108 megawatts electric. The licensee intends to implement the uprate by the end of May.

NRC previously published a notice about the power uprate application in the Federal Register providing the public an opportunity to comment or request a hearing. No comments or hearing requests were received by the NRC.

The NRC’s safety evaluation of the requested power uprate for the plant focused on several areas, including nuclear steam supply systems, instrumentation and control systems, electrical systems, accident evaluations, radiological consequences, operations, and other technical specification changes. The NRC staff determined that the licensee could safely increase the power output of the reactor primarily through increased feedwater flow measurement accuracy.
