RADIATION SHIELDING METHOD AND APPARATUS, AND METHOD FOR PROCESSING STRUCTURE |
摘要 |
A radiation shielding method and a device, and a method of processing a structure, in which a first radiation-shielded region (A1) is provided by disposing a first radiation-shielding device (100) outside a nuclear reactor vessel (41), a neutron flux detector (77) is moved into the radiation-shielded region (A1) through a conduit tube (65) by moving a thimble tube (68) from the nuclear reactor vessel (41), and an inspection/repair work of the nuclear reactor vessel (41) is then performed, so that an amount of radiation delivered to a worker can be easily and sufficiently reduced. |
