The US-APWR, developed especially for use in the United States, is an economically efficient, reliable, safe, and well-proven 1,700 MW class plant based on the advanced pressurized water reactor (APWR), which has been already developed in Japan. It utilizes the latest and best technology such as high-performance steam generators and turbines, complies with US regulatory requirements such as enhanced safety power systems, reflects US customer needs such as reduced generation costs for long cycle operation, and applies US site conditions which enable a compact building layout based on moderate seismic conditions. The design certification (DC) application to the U.S. Nuclear Regulatory Commission (NRC) is scheduled for December 2007 and efforts to obtain orders will be strengthened, targeting electric utilities in the US.
