摘要： PURPOSE: To remove effectively the radiative iodine discharged from the nuclear power installations by using a metallic adhesive adsorbent satisfying the prescribed conditions.
CONSTITUTION: The waste gas contg. radiative iodine is treated through a packed filter of an adsorbent (e.g. zeolite) wherein metal (e.g. silver) or a metal lic (e.g. silver) compds. allowing to react with iodine is adhered thereon and the following three conditions are simultaneously satisfied. u≤24/dp
2 , u≤10
5 ×dp
2 , u≥0.2 but dp is the average particle size (mm) of the adsorbent and (u) is the linear velocity (cm/s). As a result, the radiative iodine discharged from the nuclear power installations can be effectively removed.

摘要： PURPOSE:To improve remote controllability by providing a guide flange which contains a chain-like fastening mechanism which connects a clamp to a clamp plate, and arranging the guide flange movably in an axial direction with respect to one piping. CONSTITUTION:Conical flanges 1a, 2a are respectively formed on ends of pipings 1, 2. A gasket 3 is arranged between the opposed flanges 1a and 2a. Clamp groups 4 are arranged so as to fit to conical portions of the flanges 1a, 2a. A guide flange 5 housing the clamp group 4 is slidably engaged with an outer periphery 1b of the piping 1. A projection 5e is formed on an end of the guide flange 5 so as to be moved by a remote control device, while a projection 1c is formed on the piping 1. The guide flange 5 is moved by attracting the projections. A clamp chain is not necessarily detached in every installation, and can be kept attached. Installation operation is simplified.

摘要： PURPOSE:To obtain a blanket of a fusion device in a simple structure which can be manufactured easily by avoiding direct contact between neutron multiplication material pebble and a breeder material pebble which are mixed and filled and easily react at high temperature and then positively preventing the temperature of a multiplication blanket from being reduced as compared with tritium release temperature extremely. CONSTITUTION:A zirconium coating 29 is formed at least on one of neutron multiplication material pebble 32 and a breeder material pebble 31, thus suppressing their direct contact and reaction at high temperature. Also, a fin 33 is attached to a cooling pipe 30 with a smaller pitch than the diameters of the pebbles 31 and 32, thus preventing excessive reduction in temperature due to direct contact on the entire surface between the pebbles and the cooling pipe. The length of the fin 33 is adjusted and the thickness of a helium gas gap layer 22 is adjusted.

摘要： PURPOSE:To suppress the decease in the concn. of the nitrous acid in a nitric acid soln. by suppressing the decomposition of the nitrous acid by the coating and forming of a gas-liquid boundary. CONSTITUTION:The nitric acid soln. 3 and sheared pieces 4 of used nuclear fuel are introduced into a dissolving device 2 and thereafter, a radiation resistant oil 1 is added thereto to coat the soln. boundary. The sheared pieces 4 are gradually dissolved when the soln. 3 is heated by driving a heater 5. The nitrous acid is formed with the dissolution at this time, but the soln. boudary is coated, the transfer of the nitrous acid to a gaseous phase is prevented. The decrease in the concn. of the nitrous acid in the soln. is suppressed and the specified conc. is maintained. The formation of volatile RuO is suppressed in this way and the contamination by Ru is suppressed. In addition, the formation of high valency ions to accelerate corrosion is suppressed and the corrosion of the material of the concentration device is lessened.

摘要： PURPOSE:To lower the temperature of a low tritium permeation layer in operation by protecting the low tritium permeation layer from the heat load of plasma or corpuscular radiation and the load of the corpuscular radiation by a heat-resistant member for the purpose of intercepting heat. CONSTITUTION:A heat-resistant member 10 is interposed between a low tritium permeation layer and a core plasma and thereby the low tritium permeation layer is shielded so that the plasma or corpuscular radiation may not strike directly on the layer. By interposing the heat-resistant member in this way, the low tritium permeation layer can be kept at a low temperature. In addition, the permeation of tritium can be suppressed effectively.
