| 主权项 | 1. A nozzle mounting structure for mounting a nozzle penetrating through a reactor vessel having a hemispherical concave inner surface, the nozzle mounting structure comprising: a removed concave portion in which a base material on an inner surface side of the reactor vessel is removed in a symmetrical shape around a normal line on a hemispherical concave inner surface of the reactor vessel; a flange provided on the nozzle, formed in a same symmetrical shape as that of the removed concave portion around the normal line, and inserted into the removed concave portion; and a weld part provided around the normal line for welding the flange to the reactor vessel. | ||
