A hydrogen occlusion member (1A) coated in advance with an insulation layer (3) capable of preventing penetration of hydrogen nuclei therethrough is inserted, only at a portion (4) thereof which is not coated with the insulation layer (3), into a reactor vessel (7) so that hydrogen nuclei are occluded into the hydrogen occlusion member (1A), and then the portion (4) of the hydrogen occlusion member (1A) is removed from the reactor vessel (7). Thereafter, also the portion (4) which is not coated with the insulation layer (3) is coated with an insulation layer (3), and the hydrogen occlusion member (1A) is accommodated into and kept in a protective case (11) if necessary. <IMAGE> |
