Abstract: In a zirconium-alloy fuel element cladding, a method for generating regions of coarse and fine intermetallic precipitates across the cladding wall is provided. The method includes steps of specific heat treatments and anneals that coarsen precipitates in the bulk of the cladding. The method also includes at least one step in which an outer region (exterior) of the cladding is heated to the beta or alpha plus beta phase, while an inner region (interior) is maintained at a temperature at which little or no metallurgical change occurs. This method produces a composite cladding in which the outer region comprises fine precipitates and the inner region comprises coarse precipitates.

Abstract: An upper hold-down spring structure for a nuclear reactor fuel assembly. A hold down spring 20 mounted on an upper surface of an upper nozzle 11 of a fuel assembly for a pressurized water reactor is composed of an upper plate spring 21 having plastic spring characteristics and a lower plate spring 23, base ends of which are fixed with a fastening bolt 18 at a common position. The upper spring 21 and the lower spring 23 are made of precipitation hardened nickel base alloy and the thickness of the springs are determined so as to keep the stresses generated less sensitive to stress corrosion cracking.
Abstract translation: 用于核反应堆燃料组件的上压紧弹簧结构。 安装在压水反应堆用燃料组件的上喷嘴11的上表面上的按压弹簧20由具有塑料弹簧特性的上板簧21和下板簧23组成，底板弹簧21的基端固定有 在同一位置的紧固螺栓18。 上弹簧21和下弹簧23由沉淀硬化的镍基合金制成，弹簧的厚度被确定为保持对应力腐蚀开裂不敏感的应力。
