HOLJE FOR KERNREAKTORBRENSLEELEMENT

摘要

The casing is made up of a number of identical compartments of prismatic shape in which are placed vertically either one or a number of fuel element bundles which are not secured to the casing, the casing walls being provided with means for guiding control rods, supplying emergency coolant and positioning measuring devices. At least some of the casing walls are constituted by two parallel thin metal sheets welded at intervals to stiffening webs which extend between the two metal sheets to the full height of the casing and parallel to the axis of the reactor.
