Abstract
(EN)
The present invention relates to a drying apparatus for drying a canister for spent nuclear fuel transportation and storage, a control method therefor, and a radiation shielding geometry for a radiation dose rate detector therefor. The purpose of the present invention is to cause no stress to a facility pipe by comprising a radiation shielding geometry for a radiation dose rate detector which comprises a non-contaminated circulatory system and a contaminated circulatory system, prevents a drying apparatus from being contaminated even in the case of a canister having damaged spent nuclear fuel loaded therein, is easily assembled in an appropriate thickness according to a radiation dose rate, and measures the radiation dose rate of only the pipe to be measured. The present invention is characterized by comprising: a fourth gas circulation line which branches from a second gas circulation line and connects a gas cooling apparatus and a canister to communicate with each other separately from the second gas circulation line; a branch valve means mounted on the branch point where the second and fourth gas circulation lines branch; a fifth gas circulation line which is connected to the fourth gas circulation line so as to communicate with same and which connects the gas cooling apparatus and a non-reactive gas source to communicate with each other; a particle filter mounted on the fifth gas circulation line; a third gas circulation pump mounted on the fifth gas circulation line; and a radiation dose rate detector installed in a space outside the second gas circulation line between the canister and the branch valve means.

La présente invention concerne un appareil de séchage pour sécher un silo pour le transport et le stockage de combustible nucléaire épuisé, un procédé de commande associé, et une géométrie de blindage contre le rayonnement pour un détecteur de débit de dose de rayonnement associé. L'objet de la présente invention est de ne pas provoquer de contrainte sur un tuyau d'installation en comprenant une géométrie de blindage contre le rayonnement pour un détecteur de débit de dose de rayonnement qui comprend un système circulatoire non contaminé et un système circulatoire contaminé, empêche un appareil de séchage d'être contaminé même dans le cas d'un silo ayant un combustible nucléaire épuisé endommagé chargé en son sein, est facilement assemblé dans une épaisseur appropriée en fonction d'un débit de dose de rayonnement, et mesure le débit de dose de rayonnement uniquement du tuyau à mesurer. La présente invention est caractérisée en ce qu'elle comprend : une quatrième ligne de circulation de gaz qui se ramifie à partir d'une deuxième ligne de circulation de gaz et relie un appareil de refroidissement de gaz et un silo pour communiquer entre eux séparément de la deuxième ligne de circulation de gaz; un moyen de vanne de dérivation monté sur le point de ramification où les deuxième et quatrième lignes de circulation de gaz se ramifient; une cinquième ligne de circulation de gaz qui est reliée à la quatrième ligne de circulation de gaz de façon à communiquer avec celle-ci et qui relie l'appareil de refroidissement de gaz et une source de gaz non réactif pour communiquer entre eux; un filtre à particules monté sur la cinquième ligne de circulation de gaz; une troisième pompe de circulation de gaz montée sur la cinquième ligne de circulation de gaz; et un détecteur de débit de dose de rayonnement installé dans un espace à l'extérieur de la deuxième ligne de circulation de gaz entre le silo et le moyen de vanne de dérivation.
