Abstract

In a nuclear reactor building of a steel plate concrete structure that houses a pressure containment vessel formed with a plurality of penetration ports penetrating the pressure containment vessel on the periphery thereof and includes a biological shielding wall disposed outside the pressure containment vessel. The pressure containment vessel is vertically divided into a plurality of blocks so that each of the blocks has one or more pressure containment vessel penetration ports arranged on a same horizontal plane, and the reactor building including the biological shielding wall is divided into a plurality of modules by the horizontal plane.

Dependent claims

A nuclear reactor building comprising:

a pressure containment vessel formed with a plurality of pressure containment vessel penetration ports in the periphery thereof, wherein the pressure containment vessel is vertically divided into a plurality of blocks, each of the blocks has one or more pressure containment vessel penetration ports, wherein for each one of the blocks, all of the one or more containment vessel penetration ports of the respective one of the blocks are arranged on a same horizontal plane;
and
a biological shielding wall disposed outside the pressure containment vessel, wherein the biological shielding wall is divided into a plurality of modules by plural horizontal planes, and at least a portion of the biological shielding wall comprises a steel plate reinforced concrete.
