Study on Design Technique Scheme of US-APWR Nuclear Power Plant

The US-APWR, developed especially for use in the United States, is an economically efficient, reliable, safe, and well-proven 1 700 MW class advanced nuclear power plant based on the advanced pressurized water reactor (APWR), which has been developed in Japan. It utilizes the latest and best technology such as high performance steam generators, turbines and advanced accumulator tank, complies with US regulatory requirements such as enhanced safety power systems, reflects the needs of US customer such as reducing generation costs for long cycle operation, and applies US site conditions which enable a compact building layout based on moderate seismic conditions. The main design technique scheme and feature of US-APWR were analyzed, and the main plant specification, main component design, safety design, layout design, turbine plant and instrument and control system, etc. were introduced.
