COMPARTMENTED NUCLEAR REACTOR FUEL ELEMENT
An improved fuel element is designed for use in pressurized water reactors. The element consists of an elongated cladding tube with a column of fuel pellets inserted within. The fuel pellets are divided into discrete groups in compartments formed by spacing discs; the advantage of this arrangement is that thinner cladding tubes can be used and, in event of rupture in the cladding tube, the contents of only one compartment would be exposed to the coolant. In one modification of the fuel element, outer and inner cladding tubes are used with annular fuel pellets to extend the heat surface of the element, with annular spacing washers forming the compartments. Procedures are given for the fabrication and assembly of the fuel element components. (D.L.C.)
