Abstract

PURPOSE: To enable an each approach of an operator to cooling system units and to obtain an economic plant by mounting neutron absorbing member at through tubes wall surface for scattering leaked neutrons to largely reduce the leaked neutrons.
CONSTITUTION: A reactor pressure vessel 1 having internally a core 2 is arranged in a reactor container pit chamber 4 formed of first shielding wall 3 of living being shielding concrete wall. Second shielding wall 5 is provided at the outer periphery of the wall 3 with a cooling system chamber 6 formed between the walls 3 and 5 and with tubes 7 such as coolant exhaust tubes or the like connected to the vessel 1 connected through the wall 3 to the cooling units in the cooling system chamber 6. A neutron absorbing member 8 of neutron moderator 10 and neutron absorber 11 is provided to surround the tubes 7 at the side wall surface of the chamber 6, and similar neutron absorbing member 9 to the member 8 is provided at the wall 5
