摘要： PURPOSE:to diminish a produced amount of a radioactive waste substantially by providing a process to obtain a grouting material which is the radioactive waste added with a cement material and the like, and another process to measure a radioactivity level of the said grouting material. CONSTITUTION:Concerning about radioactive wastes such as an unsolved portion separated by a treatment of a decontamination liquid waste, its radioactivity level is measured and evaluated. To the radioactive waste evaluated its radioactivity level, a cement and the like are added, mixed and then a production 16 of a grouting material to stabilize activated metals, contaminated metals, radioactive concrete and so on, is conducted. On the other hand, received radioactive wastes are treated according to their material characteristics, their radioactive situations and their radioactive levels. Packaged 5 radioactive wastes are required to be conducted a stabilization and solidification treatments 11 for the wastes not so as to move around in the package during transportation, and the said grouting material can be used for the stabilization. For the stabilized and solidified radioactive wastes, a package inspection is applied and thereafter the wastes are transported to a storage facility or a disposal site according to their radioactivity levels.

摘要： PURPOSE:To enable efficient and thorough decontamination by decontaminating waste failing to be decontaminated down to a prescribed level further by a regular decontami nation consisting of at least two kinds of different decontamination methods according to shapes. CONSTITUTION:The radioactive contaminating metal waste is taken out of a container by a waste accepting part 1 and is subjected to a predecontamination 2 by which clads, etc., are removed. The waste taken out of the predecontamination 2 is cleaned in a rinse tank 3 and is subjected to the measurement of the radioactivity level by a measuring and discriminating system 4, by which the waste is discriminated to the decontaminated waste 11 and the waste failing to be decontaminated. The waste failing to be decontaminated is discriminated in shapes to an electrolytic polishing decontamination 6 and an oxidation-reduction decontamination 7 according to the shapes thereof. The waste taken out of the decontaminations 6, 7 is further subjected to cleaning of the decontaminating agent, etc., in a rinse tank 8 and thereafter, the radioactivity level thereof is measured by the measuring and discriminating system 9, by which the waste is discriminated to the decontaminated waste 12 and the waste failing to be decontaminated. The waste failing to be decontaminated down to the prescribed radioactivity level is again subjected to the regular decontamination in the regular decontamination 5.

摘要： PURPOSE:To exactly detect the defects occurring a fluid separation membrane module in order to securely maintain and control the module by a method in which the same kind of fluid is supplied under the same pressure before and after the beginning to use the module, and then the flow rates of respective permeated fluids are measured and compared. CONSTITUTION:Before the beginning of use of a module 1, a fluid is supplied under a given pressure and the flow rate GA of the permeated fluid is measured. Then, after the beginning of use of the module 1, a stop valve 28 is closed, a valve 25 is opened, and the same fluid as the fluid used for measurement of GA is supplied from a fluid supply mechanism 26 to a high-pressure side space 4 under the same pressure. And, the flow rate GA' of the fluid coming out of a low-pressure side space 5 through a separation membrane 3 is measured by a flow meter 30. And, since GA' becomes greater than GA in case where defect occurs in the module 1 after the biginning of use, GA' is compared with GA to inspect whether defect has occurred after the beginning of use.

摘要： PURPOSE:To safely obtain a fixed quantity of an absorbing liquid in a carbon dioxide absorbing tank without touching the absorbing liquid and/or absorbing vapor, by adequately arranging a weighing tank, valves, etc. CONSTITUTION:When opening a drain valve 10, a carbon dioxide absorbing liquid 12 in an absorbing liquid supply tank 8 is admitted into a weighing tank 5 by gravity. Gas pressure in the weighing tank 5 and the absorbing liquid supply tank 8 is automatically adjusted by means of a connecting pipe 11, and the absorbing liquid 12 fills the weighing tank 5 and rises up to a liquid level of the absorbing liquid 12 in the absorbing liquid supply tank 8 in the connecting pipe 11. If the inner volume of the connecting pipe 11 is sufficiently made little, a fixed quantity of the absorbing liquid 12 can continually be gained in the weighing tank 5. When the drain valve 10 is closed and a drain valve 9 and a gas pressure adjusting valve 7 are opened, the absorbing liquid in the weighing tank 5 is introduced into a carbon dioxide absorbing tank 4.
