Abstract
A radiation shielding method and a device, and a method of processing a structure, in which a first radiation-shielded region (A) is provided by disposing a first radiation-shielding device () outside a nuclear reactor vessel (), a neutron flux detector () is moved into the radiation-shielded region (A) through a conduit tube () by moving a thimble tube () from the nuclear reactor vessel (), and an inspection/repair work of the nuclear reactor vessel () is then performed, so that an amount of radiation delivered to a worker can be easily and sufficiently reduced.
