摘要： An object is to provide a method and an apparatus for improving a residual stress in a tubular body, which are enabled to improve the residual stress reliably by clearly defining controlling rage for treatment conditions without depending on an installation state and configuration of the tubular body. When a cylindrical tubular body (2) is improved in its residual stress by locally irradiating an outer-circumferential surface of a welded portion (C) of the tubular body (2) with laser beams (5a) and by moving an irradiation area (s) in an circumferential direction, a plurality thermocouples (9) are installed on the tubular body (2) to be improved, a temperature history of the outer surface of the tubular body (2) by the irradiation of the laser beam (5a) is managed by measuring the temperature history itself.

摘要： In a method for dismantling a heat exchanger installed in a nuclear reactor building, a contamination controlled area is minimized. The method includes: an introducing step of introducing a part of a heat exchanger (100) in a contamination controlled area, the introducing step including providing the contamination controlled area in a part of the nuclear reactor building, suspending the heat exchanger by a jack down unit provided in the nuclear reactor building, and lowering the heat exchanger; a first cutting step of cutting the part of the suspended heat exchanger by a first cutting unit (300) provided in a first cutting area in the contamination controlled area to thereby separate a sectioned cut-piece from the suspended heat exchanger; a conveying step of conveying the sectioned cut-piece from the first cutting area to a second cutting area in the contamination controlled area by a conveying unit (500) ; a second cutting step of cutting the conveyed sectioned cut-piece into small pieces by a second cutting unit (400) provided in the second cutting area; and a carrying-out step of carrying the sectioned cut-piece cut into the small pieces out of the contamination controlled area with the sectioned cut-piece packed in a container.

摘要： The current methods of removing the surface-deposited layer contaminated by radioisotopes has the disadvantage of rigorous applicability conditions in such terms as the substance to be treated, the area and the shape, so the scope of their applicability is quite limited; in addition, 100% decontamination is not guaranteed and in spite of more than 50% that can be decontaminated, a greater part of the deposited radioisotopes remain unremoved, limiting the decontamination performance of the methods.
Parts, structural components, etc. that have their surfaces contaminated by radioisotopes in the accelerators, nuclear reactors, RI product manufacturing factories, nuclear fuel factories, nuclear fuel reprocessing factories, etc. are decontaminated by non-thermal laser peeling without suffering re-melting, re-diffusing and re-contaminating such that upon non-thermal laser irradiation, areas near the irradiated surface are evaporated and removed faster than the heat generated in the irradiated surface is transmitted to nearby areas.
