Abstract
(EN)
A method for decommissioning a nuclear facility comprises the steps of: floating a nuclear reactor pressure vessel on a cavity; positioning a mounting device on bio-protective concrete so as to cover the cavity with the mounting device; mounting the lower part of the nuclear reactor pressure vessel on the mounting device; and cutting and decommissioning the nuclear reactor pressure vessel mounted on the mounting device.
(FR)
Procédé de mise hors service d'une installation nucléaire comprenant les étapes consistant à : faire flotter une cuve sous pression de réacteur nucléaire sur une cavité ; positionner un dispositif de montage sur du béton de protection biologique de façon à recouvrir la cavité avec le dispositif de montage ; monter la partie inférieure de la cuve sous pression de réacteur nucléaire sur le dispositif de montage ; et couper et mettre hors service la cuve sous pression de réacteur nucléaire montée sur le dispositif de montage.
(KO)
원자력 시설의 해체 방법은 원자로 압력 용기를 캐비티 상에 플로팅(floating)시키는 단계, 생체 보호 콘크리트 상에 안착 장치를 위치시켜 상기 캐비티를 상기 안착 장치로 커버하는 단계, 상기 안착 장치에 상기 원자로 압력 용기의 하부를 안착시키는 단계, 및 상기 안착 장치에 안착된 상기 원자로 압력 용기를 절단 및 해체하는 단계를 포함한다.
