Investigations of PCRV and nuclear reactor containments in China

This paper describes the state-of-the art of the research work on the mainland of China pertaining to the prestressed concrete reactor vessel and to nuclear reactor containment. The results of tests of 1 10 th scale model of a PCRV and its deep end slab are presented. The 3D linear and nonlinear stress analyses and ultimate load of these models are also described. A new type of containment, a steel-plate-concrete composite containment, is proposed and evaluated. At last, a survey of the Qin Shan Nuclear Power Plant is described.
