A spent nuclear fuel reprocessing method includes: an electrolytic valence adjustment step in which nuclides contained in the fuel solution is electrolytically reduced without removing fission products or minor actinides until valence of plutonium is at a level at which solvent extraction efficiency is low by using the valence of plutonium contained in the fuel solution as a parameter; and a nuclide separation step in which, by using an extraction solvent which extracts uranium contained in the fuel solution, uranium is distributed from the fuel solution subjected to the electrolytic valence adjustment step to the extraction solvent.

摘要： To provide a long-life refractory capable of maintaining durability under severe conditions. The castable refractory comprises a mixture containing at least one of 2 to 10 mass % of silicon carbide and 3 to 10 mass % of chamotte, as an auxiliary raw material, and a binder material, with the remaining balance being one or more main raw materials selected from corundum, mullite, bauxite, chamotte, talc and silica, and is used in an environment exposed to an alkali component-containing hot gas atmosphere. In an alkali component-containing gas atmosphere at a high temperature (750° C. or more), silicon carbide and/or chamotte are vitrified to a thickness of 1 mm or less in the surface layer of the refractory to prevent the alkali component-containing gas from intruding inside of the refractory.

摘要： A rotary encoder includes two first detection units disposed at positions that are symmetrical about a rotation axis, each of the first detection units outputting an incremental signal, and second detection unit that outputs an absolute signal φA. The rotary encoder includes a storage unit that stores a plurality of formulas for correcting errors of the incremental signals, the formulas being different from each other in accordance with the signal φA, and the errors being generated due to eccentricity; a calculation unit that calculates a corrected phase φI by performing operation on the incremental signals by using one of the formulas corresponding to the signal φA; and a generation unit that generates a rotation angle of the scale on the basis of the phase φI and the signal φA.
