The Nuclear Regulatory Commission has approved a request by Nuclear Management
Company to increase the generating capacity of the Duane Arnold nuclear power
plant by about 15.3 percent, or 80 megawatts.
The power uprate at the plant, near Cedar Rapids, Iowa, will increase the
generating capacity of the reactor to about 600 megawatts of electricity.
The facility intends to implement the power increase immediately. The application
for the increase in power was submitted to the NRC on November 16, 2000.
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 technical specification changes. The NRC staff
determined that the licensee could safely increase the power output of the
reactor with replacement of the main transformer and other modifications to
plant equipment.
