MAGAZINE FOR FUEL ASSEMBLIES WITH SPENT NUCLEAR FUEL

摘要

A magazine for storage of nuclear fuel assemblies with spent fuel in the intermediate storages. In a magazine with a tubular casing (2), intersecting plate (6, 7) form a number of channels (8) for one assembly each. At their end portions the plates (6, 7) are fixedly joined to each other. Their central portions are formed with slits, causing the walls of the formed channels (8) to be resilient perpendicular to the plane of the walls. This limits the friction resistance between a fuel assembly and a channel wall when inserting an assembly with such deformations that it will make contact with a channel wall. Compared with prior art magazines, the channel cross-section may be reduced and greater packing density be obtained.
