摘要： PROBLEM TO BE SOLVED: To make a facility compact, reduce a maintenance work for equipment, lower the extent of exposure to a radiation and reduce the generation of a waste material by improving and recovering a treatment flowrate. SOLUTION: A filter 3 is connected to a collection tank 1 via a pump 2, and a sump tank 4 is connected to the outlet of the filter 3. The outlet of the filter 3 is connected to the collection tank 1 via a return pipe 5, and the cake delivery side of the filter 3 is connected to a drum 6. Also, an activated powder carbon feeder 7 is connected to the collection tank 1, and a chemical tank 8 is connected to the collection tank 7 and the filter 3 via chemical feed lines 12 and 9. Furthermore, the filter 3 has agitation vanes (b) and agitation liquids (c) alternately arranged in a filtration chamber (a) at a small gap, and the agitation vanes (b) rotate at a constant speed on the rotation of a motor (d). Also, a filter board (c) has a filtrated liquid discharge mechanism (e) and filter cloth is attached to both side of the filter board (c). In addition, a filter vent 10 and a filter drain 11 are connected to the outlet of the filter 3.

摘要： PROBLEM TO BE SOLVED: To obtain a solidified body which is stable over a long period, and to contribute to load reduction and maintainability improvement of a blender. SOLUTION: A sodium sulfate waste fluid 1 containing sulfate produced from a nuclear power plant or the like is evaporated to be dried 2 by a dehydrator into dry powder 3. Water 5 and a preparation material 4 producing a sulfo calcium aluminate mineral are added to the dry powder 3 and mixed 6. A hydraulic inorganic solidifying material 7 is added to the mixture, mixed 8, and put in 9 a solidification container for obtaining a solidified body 10. By this, radioactive waste fluid with sulfate as a main component can be made into a highly volume reductive and stable cement solidified body.

摘要： PROBLEM TO BE SOLVED: To surely and speedily transmit the report of local information to all the residents in that area at low cost in a simple configuration and to enable the local resident to immediately recognize emergency abnormality even when such abnormality occurs. SOLUTION: A host computer 7 at a transmission base 6 is connected through a general communication network 5 to information terminal equipment 3 provided for every local resident home. The host computer 7 transmits the local information through the general communication network 5. When the local resident at A home 1 presses a power source on/off button, that button is turned on, a CPU turns on the power sources of a television 2 and the information terminal equipment 3 and by controlling the decoding of character graphic information as the local information, character graphic images based on the local information are displayed on the screen of the television 2. Thus, the local information can be surely and speedily transmitted to all the local residents and that transmission can be executed at low cost.

摘要： PROBLEM TO BE SOLVED: To provide a radiation measuring device capable of grasping the state, the size, the position or the like of a radioactive material (γ-ray source) inside a measuring object as a radiation image, or detecting remotely the direction or the position where the radioactive material exists, or performing nondestructive inspection of a structure including the radioactive material in a radiation background environment or to a very narrow part.
SOLUTION: This device is equipped with a sensor head 6 arranged oppositely to the measuring object 12 emitting γ-rays, an image fiber 4 connected to the sensor head 6, for transmitting an image of the measuring object 12, a camera 7 connected to the terminal of the image fiber 4, and an image processing device 9 connected to the camera 7. The sensor head 6 has a constitution equipped with a multi-collimator 1 formed by bundling a plurality of X-ray/γ-ray waveguides, for allowing a prescribed directional component in the γ-ray to pass, a fluorescent screen 3 for converting the γ-ray passing the multi-collimator 1 into visible light, and a shielding container 5 for covering the multi-collimator 1 and the fluorescent screen 3 to reduce a radiation noise.
