The objective is to develop the internationally competitive domestic nuclear power plant that is highly economical and safety. The research on the basic design of the hyper core density ABWR (Advanced Boiling Water Reactor) is conducted and subjects for the basic design are investigated. To achieve the rated core power of over 1,650MWe which exceeds the EPR (European Pressurized Water Reactor), the core power density of ABWR is up-rated more than 25%. By making use of conventional ABWR design, it is possible to reduce construction costs with maintaining the fundamental safety features. Three focused subjects on this project are, "development of the hyper core power density fuel", "development of the coupled neutronic and thermal-hydraulic stability evaluation method" for the enhanced power plant of which stability is degraded, and "improvement of the steam separator performance" for the high quality condition. Current status of the technical developments is reported.
