METHOD FOR PRODUCING FUEL ASSEMBLY FROM FUEL ELEMENTS Russian patent published in 2002 - IPC

Abstract RU 2181220 C2

FIELD: nuclear power engineering; fuel assemblies for nuclear reactors. SUBSTANCE: method involves covering fuel assemblies with varnish mixture, drying out, applying liquid lubricant in the course of press-fitting the fuel element, and press-fitting fuel elements in cells of spacer grids with reference to grid chart. Fuel elements are press-fitted into cells of spacer grids with cone of bottom end part set forward without using conical tips. Diameters of inscribed circumferences in spacer-grid cells do not exceed permissible minimum for fuel element diameter. Proposed method provides for unattended assembling of fuel elements and using mixed nuclear fuels. EFFECT: enhanced output and quality of fuel assemblies. 2 dwg
