摘要： The invention concerns a method for making flat thin elements which consists in: producing a zirconium alloy blank also containing, besides the inevitable impurities, 0.8 to 1.3 % of niobium, 1100 to 1800 ppm of oxygen, and 10 to 35 ppm of sulphur; carrying out a β hardening and hot rolling to obtain a blank and performing on it at least three cold rolling passes with intermediate annealing heat treatments. One of the intermediate heat treatments is performed for a duration of at least 5 hours at a temperature less than 560 °C and all the optional treatments subsequent to the long treatment are carried out at a temperature less than 620 °C for not more than 15 minutes.

摘要： The invention relates to a method for separating zirconium and hafnium tetrachloride with the aid of a solvent comprising an alkaline metal solvent formed from an alkaline metal chloride salt and an acid metal chloride A, e.g. a chloroaluminate or an alkaline chloroferrate, and a metal chloride or an acid metaloid chloride B, whose acidity value is lower than that of the acid metal chloride A. The metal chloride or acid metalloid chloride B has an acidity value which is lower than that of the acid metal chloride A. The metal chloride or acid metalloid chloride B is preferably chosen from Mg, Zn and Cu chloride. The method can involve separation in a continuous manner, by selective absorption of the tetrachloride vapours by the solvent in a substantially or totally melted state.

摘要： The invention concerns a method for making a flat zirconium alloy product, characterized in that it consists in: preparing a zirconium alloy ingot containing at least 95 % of zirconium; shaping said alloy to obtain a flat product; subjecting said product to a hardening treatment β to obtain an acicular structure; subjecting said product to a single-pass rolling treatment without intermediate annealing, between room temperature and 200 °C, with a reduction rate between 2 and 20 %; and subjecting said flat product to an annealing treatment α or α + β between 500 and 800 °C for 2 minutes to 10 hours. The invention also concerns the resulting flat zirconium alloy product, and a fuel assembly component for a nuclear power plant reactor obtained by shaping said product.
