Preliminary Study on Response Law of Prestressed Concrete Containment after LOCA in Certain NPP
摘要
Abstract
After loss of coolant accident (LOCA ) occurs in nuclear power plant ,the temperature field distribution in prestressed concrete containment (PCC ) is nonlinear significantly . However , the detailed calculation method combining temperature and pressure is not proposed in current PCC design code in China .In this paper ,the finite element model for PCC including prestressed tendons was built by using ANSYS code and the temperature field under LOCA was calculated . The calculation results were compared with the theoretical results ,and the accuracy of the proposed model was veri‐fied .The response law of PCC under high pressure and high temperature was prelimina‐rily analysed ,and the effects of temperature and prestressed tendons on PCC were con‐cluded ,w hich can provide reference to the concrete containment design .关键词
