Filed: 1989-08-04
Abstract: PURPOSE:To intend an improvement of an anti-brittleness-cracking of a cladding tube by previously sticking and uniformly dispersing a cadmium on an inner surface of the fuel cladding tube which consists of a zirconium base alloy. CONSTITUTION:For the first place, a zirconium alloy is molten to form an ingot and thereafter a hollow billet is formed by a forge forming and finally a thick wall material tube is obtained by a hot extruding. After reducing a diameter of the tube by a cold rolling, an intermediate annealing is applied and the cold rolling and the annealing are repeated again, finally to obtain a small diameter tube. A required number of the manufactured small diameter tubes (fuel cladding tubes) are bundled and housed in a vessel, and then are heated up for around 100 hours, at around 350 deg.C and in a vacuum condition. A molten Cd is made to flow on the inner surface of the fuel cladding tube in the vessel in order to contact the inner surface to the Cd.

Abstract: PURPOSE:To remove arc marks and swarf existing in a machining gap by dint of an electrodischarge machining impact, by aiming at safety for a switching element or the like in a way of cutting off a discharge current at the time of a short, while letting a pulse current flow at the specified interval even if a small quantity. CONSTITUTION:The resistance value of a safety resistor 4 inserted into a circuit is set to the smallest possible extent so as to be the low resistance value of such an extent as making a current of more than the rated current value flow into a switching element 5, for example, so as to be less than one half of the resistance value letting a rated current flow, in selection. With this constitution, power to be consumed at this discharge circuit comes yet smaller than ever before. Next, output timing of a controller 6 or a short discriminator 8 should be set in advance so as to turn off the switching element 5 in case of being short-circuited at a machining gap G. And, a pulse current is made to flow into this machining gap at the specified interval, giving an electric discharge machining impact to arc marks and swarf, and they are removed whereby pulse electric discharge machining is automatically resumable.
