【 摘 要 】

Safety and economy are important criteria for measuring new type of nuclear power units. How to preliminarily calculate and improve the availability of NPP at the design phase becomes the main goal in the future,which can avoid a lot of resources consumption due to design defects to increase the availability of units during the follow-up operation. At present, European Utility Requirements (EUR) and Utility Requirement Document (URD) all require the availability of more than 90% in third-generation nuclear power units. Therefore, based on the existing operation and maintenance data of nuclear power units, a dynamic calculation model of availability of nuclear power units applicable to the design phase is constructed. Adapting to the design improvements of nuclear power units, the dynamic calculation model simulates a possible outage critical path of nuclear power units through iterative calculation and evaluates the availability of the units during the design phase, so as to improve the availability of the units, which is forward-looking and practical in the power generation of nuclear power units in the future.
