Abstract: The invention concerns a process for the production of a tubular zircaloy 2 blank which is internally clad with zirconium for use in producing composite cladding tubes for nuclear fuel. The internal zirconium cladding is rendered suitable for ultrasound monitoring of its thickness by an appropriate thermomechanical treatment which takes place during one or more of the production steps for said blank. The aim is to adjust the grain size to an ASTM index of between 9 and 12 for the zircaloy 2 and between 6 and 10 for the unalloyed zirconium, retaining a grain size difference between the zircaloy 2 and the unalloyed zirconium of at least 2 ASTM index numbers.

Abstract: The present invention relates to a process for the manufacture of zirconium based tubes formed from layers of varying composition. The process consists in preparing the tubular blank which is intended to form the outer layer of the tube by rolling-soldering a sheet, and then in fitting it onto another tubular blank, or core block, of smaller diameter, which is obtained by piercing a small bar, and which may be coated on the inside with a plating, in soldering the ends of said blanks in order to subject the assembly to a treatment of placing it in solution in a beta phase, followed by soaking it in water and drawing it. The invention is used for the production of Duplex or Triplex type tubes with an improvement in the gross weight of zirconium needed to make 1000 kg of useful metal, with good adherence being obtained between the layers of said tube.

Abstract: A process for the manufacture of a rough-shaped, cold-rolled cladding tube of "Zircaloy 2" or "Zircaloy 4", in which(a) an ingot of the alloy is transformed by hot working and the bar obtained is cut up into billets,(b) the bar or the billet is then immersed from the .beta. range,(c) at least one billet which has thus been immersed is extruded in the .alpha. range,(d) the rough shape extruded is cold-rolled and heat-treated to give rise to a cold-rolled, rough-shaped cladding tube,wherein the hot working is first carried out in the .beta. range with a cross-sectional reduction ratio of at least 1.5 and then in the .alpha. range with a cross-sectional reduction ratio of at least 3, is disclosed.
