摘要： An embodiment of a nuclear power plant has: a reactor vessel (11) containing a core (10); a reactor containment vessel (12) containing the reactor vessel (12); and a radiation heat reflecting member (30) disposed at a portion below the reactor vessel (11) inside the reactor containment vessel (12). The radiation heat reflecting member (30) may block radiation heat, which is emitted toward a side wall surface (23) of the reactor containment vessel (12) from the core (31) that has been put in a molten state by an accident and flowed downward from the reactor vessel (11) to be accumulated at a lower portion (19) of the reactor containment vessel (12). The radiation heat reflecting member (47) may block radiation heat, which is emitted toward a supporting structure (42) supporting devices (44) disposed inside the reactor containment vessel (12).

摘要： A core catcher includes a holding surface that catches and holds corium and that introduces a coolant with which surroundings of the core catcher are filled into the core catcher and cool a whole of the core catcher by heat exchange with the introduced coolant. The holding surface and the cooling unit are constructed by arranging blocks which each include a polyhedron having at least one pair of parallel surfaces and having opening portion formed in a surface located in a lateral direction when a first surface that is one of the parallel surfaces is arranged as a bottom surface and are configured such that the polyhedrons communicate with each other via the opening portion when the polyhedrons are arranged adjacent in the lateral direction. The core catcher, as described above, can be achieved easier installation of the blocks without an increase in installation cost.
