FIELD: nuclear power engineering; nuclear-reactor uranium fuel magazines.
SUBSTANCE: nuclear-reactor fuel magazine has top part and bottom part joined by means of hexahedral tube. Top part has spring block of six spring-loaded stops and hexagonal bundle of fuel elements. Spring-loaded stops are disposed in upper-end bores of top part and protrude from the latter. Fuel elements are held in spacer grids disposed lengthwise of the tube and are installed in bottom support grid. Bottom support grid abuts against bottom part. Fuel-element lower end caps are additionally tightly fixed in support grid by means of locating members.
EFFECT: enhanced reliability of fuel magazine under severe operating conditions existing in reactors of various design forms.
