摘要： A method for detecting gas leakage from a radioactive material sealed container includes measuring a temperature at a bottom portion of a metallic sealed container. A feeding air temperature of external air passing between the metallic sealed container and a concrete-made storage container is also measured. Presence of leakage of inactive gas is determined by comparing the temperatures or by utilizing a physical amount calculated by using the temperatures.

摘要： The present invention relates to high-density coal-water mixed fuel and a producing method thereof and aims to reduce an amount of dispersant to be used in the coal-water mixed fuel having the good fluidity with the increased density and obtain the a coal-water mixed fuel from pulverized coals produced by dry milling at low cost. According to this invention, in case of obtaining the high-density coal-water mixed fuel such as a CWM by mixing the pulverized coals ground to provide a predetermined particle size distribution, water and the dispersant, the hydrophilic colloid which causes the protective effect with respect to the pulverized coals is added and mixed preferably before adding the dispersant so that the high-density coal-water mixed fuel which includes the hydrophilic colloid and a reduced amount of a surface active agent used can be provided. An amount of the hydrophilic colloid to be added is less than 1 wt % of the entire CWM and larger than an amount for causing reciprocal aggregation with the pulverized coals, or more preferably it is in the order from ppm to ppt. Further, when the pulverized coals are rubbed together and the angles thereof are shaved off for production from the pulverized coals, the pulverized coals are spheroidized without extremely being minimized from their original particle size, and superfine particles in the coal particles are generated, thereby enabling adjustment to provide a preferable particle size distribution as the CWM.

摘要： A method to prevent stress corrosion cracking of a storage canister 1, wherein stress corrosion cracking is prevented by applying a compressive stress to a range where a tensile residual stress is generated on a metallic body 2 by welding a cover 4 to a top 2a of the body 2. A first compressive stress is applied beforehand to a range L of the body 2 where a tensile residual stress is expected to be generated by the welding of the cover 4, the tensile residual stress is canceled by welding the cover 4 with a compressive residual stress generated in the range L, and then a second compressive stress is applied so as to generate a compressive residual stress over the range L.
