The Westinghouse AP1000 Program is aimed at making available a nuclear power plant that is economical in the U.S deregulated electrical power industry in the near-term. The AP1000 is two-loop 1000 MWe pressurizer water reactor (PWR). It is an up-rated version of the AP600. It uses passive safety systems to provide significant and measurable improvements in plant simplification, safety, reliability, investment protection and plant costs. The AP1000 uses proven technology, which builds on over 30 years of operating PWR experience. The AP600 received Design Certification by the Nuclear Regulatory Commission in 1999; the AP1000 is expected to receive DC by the NRC in 2005. The AP1000 meets all of the US utility requirements. The AP1000 retains a maximum amount of the AP600 design so as to maintain the licensing basis, detailed design information / analysis, construction plan, cost estimate developed in the $400 million dollar AP600 FOKE program. On March 28, 2002, Westinghouse submitted to the U.S. NRC the AP1000 Design Control Document and Probabilistic Risk Assessment, thereby initiating the formal licensing review process. The results presented in these documents verify the safety performance of the AP1000 and conformance with the U.S. NRC licensing requirements. Westinghouse and the NRC have been engaged in a several rounds questions/answers. Technical issues have been resolved and the NRC is preparing their Final Safety Evaluation Report. Plans are being developed for implementation of the AP1000 plant. Key factors in this planning are the economics of AP1000 in the de-regulated US electricity market, and the associated business model for licensing, constructing and operating these new plants.
