Abstract
The pressurized water reactor according an embodiment comprises: a cylindrical reactor pressure vessel () to which inlet nozzles are connected; fuel assemblies which are contained within the reactor pressure vessel (); a cylindrical reactor core barrel () which surrounds the fuel assemblies and forms an annular downcomer () between the reactor core barrel () and the inner surface of the reactor pressure vessel (); and radial supports. The radial supports are supports which are arranged below the downcomer () at intervals in the circumferential direction, each has vertical flow path formed therein, and position the reactor core barrel () and the reactor pressure vessel (). The radial supports each has, for example, a flow path-equipped radial keys () and a key groove member ().
