Title: Method for treating nitric-acid water solution containing radioactive material
IPC: G21F9/06
Filed: 1992-03-23
Abstract: PURPOSE:To collect a nitric acid sufficiently and to enable reduction of the amount of radioactive waste by a method wherein a nitric-acid water solution containing radioactive material is distilled in the existence of magnesium nitrate. CONSTITUTION:An evaporator 1 provided with a heating means 3 in the bottom part and with a mist-removing tray 4 in the top part is used. A nitric-acid water solution 2 containing a radioactive material and magnesium nitrate 11 are introduced into the evaporator 1 from the respective supply routes thereof and distillation is executed at a prescribed temperature. A nitric acid not containing the nonvolatile radioactive material and being decontaminated is collected from the top part of the evaporator. A waste liquid which contains the magnesium nitrate 11 and the radioactive material and from which the nitric acid is removed is accumulated in the bottom part. Although the distillation temperature is changed according to the content of the radioactive material and others, it is in the range of about 120 to 160 deg. under a normal pressure, for instance, and preferably in the range of 130 to 150 deg.. Almost the whole quantity of nitric acid vapor produced at the time of distillation is collected from the top part of the evaporator through the tray 4. The vapor is cooled down and liquefied by a condenser 5 and then it is reused as a decontaminated nitric-acid water solution 8 in a reprocessing plant or the like.

Title: Peeling method for sheath of optical fiber
Inventor: WATARI MASABUMI
IPC: G02B6/00
Filed: 1981-06-19
Abstract: PURPOSE:To peel easily the sheath from a fiber for infrared power transmission, where the core consists of a metallic halide specially, without damaging the core, by softening thermally the sheath of the optical fiber, where thermoplastic resin materials are used for the sheath, to peel the sheath mechanically. CONSTITUTION:In case that a thermoplastic resin 24 constituting a core 23 such as a core consisting of TlI and TlBr of an optical fiber 21 for infrared transmission is peeled, the part having a peeling length (l) from an end part 22 is heated at a temperature higher than the melting point of the resin and lower than the melting point of the core 23 to soften the resin. Two wedge-shaped blades 25 and 26 having semicircular holes, whose diameters are larger than the diameter of the core 23 and smaller than the diameter of the sheath, in centers are inserted to the position (l) distant from the end part 22 of the optical fiber and are closed to carry a peeled resin 27 away in the direction of an arrow A, thus forming an exposed core 31. Thus, the sheath is peeled easily without damaging the core 23 consisting of a halide which has a low softening point and is soft and fragile.
