摘要： PROBLEM TO BE SOLVED: To provide a structure processing method reducing time of cutting works of nuclear reactor internal structures while restraining waste quantity. SOLUTION: When an old shroud 1 is primarily cut within a nuclear reactor pressure vessel 14 and is carried out to a drier separator pool 13, and secondary cutting is performed outside a reactor as a carried-out shroud 2, an aggressive water jet cutting device using alumina as a cutting agent is applied to both a primary cutting device 20 and a secondary cutting device 21 in a similar manner, and a device for collecting secondary products at the time of cutting is also applied to both the devices. Thereby, the radioactive waste quantity can be reduced, generation of rust in the nuclear reactor can be suppressed, and increase in washing work quantity can be controlled, thus reducing a whole work period.
