摘要： A zirconium-base alloy structural member, wherein at least one element selected from phosphours, vanadium, niobium, tantalum, arsenic, antimony, bismuth, sulfur, chromium, molybdenum, tungsten, selenium, tellurium and polonium is distributed on a surface of said member, particularly to a fuel covering tube or spacer for nuclear fuel assembly which is contained the element in a surface oxide layer. The final cold-rolled fuel covering tube is produced by the steps of annealing and coating with the element in the surface oxide layer. The spacer is produced by a step of coating with the element in the surface oxide layer. A process for preparation of a zirconium-base alloy structural member includes, in addition to subjecting a zirconium-base alloy to a final plastic working step, a step of coating its surface with the element. There can be obtained a zirconium-base alloy structural member exhibiting a high corrosion resistance and having a high ductility.

摘要： @ A method of producing high-purity metal member, e.g. zirconium, is provided which reduces impurities present in the metal amd lends itself to mass production. It comprises the steps of charging raw material 6 such as sponge zirconium into a cavity 2 of a mold such as a sleeve-shaped or hearth mold, irradiating the material with electron beams 3a to melt it at a limited area of the cavity so as to form a molten metal pool and elevate the molten metal pool temperature to evaporate away impurities, and shifting the mold relative to the electron beams 3a to effect such melting portion-by-portion, in the case of high-purity sleeve formation, the electron beams are irradiated onto the raw material while rotating the mold so that melting and solidification repeatedly occur in a circumferential direction. The impurities are repeatedly exposed to the electron beams.

摘要： In a method of production of a cladding tube for a nuclear fuel element, an outer hollow billet (1) of a zirconium alloy and an inner hollow billet (2) of zirconium are joined by expansion of the inner billet (2). To improve the bonding of the inner and outer billets and provide better thickness control, a resilient member (4) is inserted in the inner hollow billet (2) and a pressure oriented axially of the two hollow billets is applied to the resilient member to pressure bond the outer wall surface of the inner billet (2) to the inner wall surface of the outer billet (1), and the interfaces of the opposite ends of the two billets are then joined and sealed. The integral hollow billet so formed is subjected to hot extrusion, cold working and heat treatment to produce a composite tube of reduced diameter and reduced thickness, and the inner and outer wall surfaces of the composite tube are polished.
