ABSTRACT:
A nuclear-reactor assembly comprising a pressure vessel for the nuclear reactor and auxiliary vessels disposed in annularly spaced relationship around the reactor pressure vessel and communicating therewith by horizontal passages in the walls between the vessels. According to the invention, the outer surface of the reactor pressure vessel, which is otherwise generally cylindrical, is formed with vertical surfaces in the region of the passages against which complementary vertical planar surfaces of the auxiliary vessels lie. The spaces between the auxiliary vessels are filled in the plane of these passages by support blocks so that the blocks together with the auxiliary vessels form a compound disk which is prestressed inwardly by a peripheral prestressing element passing around the perimeter of the disk.
