Abstract

Abstract

Reactor pressure vessel is one of the most important equipment in nuclear power plant, and its irradiation embrittlement state determines the actual operation life of nuclear power plant. A method of irradiation embrittlement time-limited aging analysis (TLAA) for reactor pressure vessel is developed by referring to foreign reactor pressure vessel safety assessment methods. This method evaluates the safety margin of pressure vessel materials under normal and accident conditions from three aspects: upper platform energy, reactor operating pressure-temperature curve and pressure bearing thermal shock. Using this method, the irradiation embrittlement TLAA safety evaluation of the reactor pressure vessel is carried out in the Qinshan Nuclear Power Plant Operation License Extension (OLE) Project. Its evaluation methods and evaluation conclusions have been recognized by the National Nuclear Safety Administration, laying the foundation for the 20-year life extension of Qinshan NPP.
