Abstract
Description
L'invention concerne un récipient-de transport et/ou de stockage pour matières radioactives, en matériau étanche aux radiations, constitue' par un corps et un couvercle blindé, avec un amortisseur des chocs, pourvu de raccords de branchement et d'une conduite de liaison entre les points supérieur et inférieur du volume intérieur, Ce récipient est destiné de préférence au transport et/ou au stockage d'éléments combustibles irradiés de réacteurs nucléaires. The invention relates to a transport and / or storage container for radioactive materials, made of radiation-tight material, constituted by a body and a shielded cover, with a shock absorber, provided with connection fittings and a pipe. of connection between the upper and lower points of the interior volume, This container is preferably intended for the transport and / or storage of irradiated fuel elements from nuclear reactors.
Les récipients de ce type sont constitués généralement -d'un corps de récipient à paroi .épaisse en matériau étanche aux radiations, dont ltorifice est obturé au moyen d'un couvercle blindé également épais. Le couvercle blindé est habituellement encastré partiellemeX ou totalement dans le corps de base et comporte une section supérieure à celle du volume intérieur du récipient. Les matériaux utilisés généralement, sont le plomb, le béton, l'acier coulé, la fonte à graphite sphéroïdal9 ou leurs combinaisons. Containers of this type generally consist of a container body with a thick wall made of radiation-tight material, the orifice of which is closed by means of an equally thick shielded cover. The shielded cover is usually partially or totally embedded in the base body and has a cross section greater than that of the interior volume of the container. The materials generally used are lead, concrete, cast steel, spheroidal graphite cast iron9 or combinations thereof.
Les récipients pour matière radioactive doivent être constitués de façon à résister aux accidents même très graves sans perdre leur étanchéité. A cet effet, la zone du couvercle est munie le plus souvent de ce quton appelle un amortisseur des chocs. Containers for radioactive material must be designed to withstand even very serious accidents without losing their seal. For this purpose, the lid area is most often provided with what is called a shock absorber.
Comme ces récipients sont normalement chargés et déchargés sous l'eau, mais transportés à sec, il est nécessaire d'y incorporer des raccords de branchement et des conduite s de liaison pour le renouvellement des fluides dans le récipient (vidange de l'eau, remplissage par l'eau, processus de rinçage et de refroidissement), un des deux raccords devant stétendre jusqu'au point le plus profond du volume intérieur du récipient. As these containers are normally loaded and unloaded under water, but transported dry, it is necessary to incorporate connection fittings and connecting pipes for the renewal of fluids in the container (draining of water, filling with water, rinsing and cooling process), one of the two connections should extend to the deepest point of the interior volume of the container.
Ces raccords de branchement sont les points faibles du récipient, qui doivent être particulièrement protégés pour le cas d'accidents graves. These connection fittings are the weak points of the container, which must be particularly protected in the event of serious accidents.
Il est connu de disposer ces raccords latéralement dans la gaine du récipient0 On connaît en outre des raccords, qui sont amenés jusqu'au rebord frontal de la gaine du récipient, ainsi qutune combinaison des raccords latéraux et des raccords dans le couvercle. Il existe aussi des récipients avec des raccords de branchement dans le couvercle blindé et avec une conduite de liaison menant au point le plus profond du volume intérieur, du récipient, qui est disposée dans le récipient mimez
Tous ces dispositifs de raccords de branchement ont cependant l'inconvénient de ne pas fournir une protection optimale en cas d'accidents ou de réduire le volume utilise du récipient.It is known to arrange these connections laterally in the container sheath. In addition, connections are known which are brought to the front edge of the container sheath, as well as a combination of the side connections and connections in the cover. There are also containers with connection fittings in the shielded cover and with a connecting line leading to the deepest point of the interior volume of the container, which is arranged in the container mimez
However, all of these connection fitting devices have the drawback of not providing optimum protection in the event of accidents or of reducing the volume used of the container.
L'invention a donc pour but de réaliser un récipient de transport et/ou de--stockage pour matières radioactives, en matériau étanche aux radiations, constitué par un corps et un couvercle blindé, avec un amortisseur des chocs, pourvu de raccords de branchement et d'une conduite de liaison entre les points supérieur et inférieur du volume intérieur ave-c des raccords de branchement disposés de telle façon qu'une protection optimale soit assuré-e contre les effets des accidents, sans rétrécir pour autant le volume utile du récipient avec des des conduites. The object of the invention is therefore to provide a transport and / or storage container for radioactive materials, made of radiation-tight material, consisting of a body and a shielded cover, with a shock absorber, provided with connection fittings. and a connecting pipe between the upper and lower points of the interior volume with connection fittings arranged in such a way as to provide optimum protection against the effects of accidents, without however reducing the useful volume of the container with pipes.
A cet effet, l'invention a pour objet un récipient caractérisé en ce que la conduite de liaison avec le point le plus profond du volume intérieur du récipient, est encastrée dans le corps, les raccords de branchement étant disposés dans le couvercle blindé et le point de jonction entre la conduite de liaison et le raccord de branchement étant rendu étanche vis-à-vis du volume intérieur du récipient au moyen d'une garniture. To this end, the invention relates to a container characterized in that the connecting pipe with the deepest point of the interior volume of the container is embedded in the body, the connection fittings being arranged in the shielded cover and the junction point between the connecting pipe and the connection fitting being sealed against the interior volume of the container by means of a gasket.
La construction selon l'invention apporte plusieurs avantages. Ainsi les raccords ne doivent pas être réalisés sur le corps de base pesant 60-100 t, mais sur le couvercle relativement plus léger, et donc plus facile à travailler. L'entretien et la réparation des raccords de branchement sont également plus faciles. The construction according to the invention provides several advantages. Thus the connections should not be made on the basic body weighing 60-100 t, but on the relatively lighter cover, and therefore easier to work. Maintenance and repair of connection fittings are also easier.
L'invention prévoit de disposer un couvercle de protection supplémentaire-par dessus le couvercle blindé et donc par dessus les raccords, de manière connue en soi. The invention provides for having an additional protective cover over the shielded cover and therefore over the fittings, in a manner known per se.
La figure du dessin annexé représente schématiquement un mode de réalisation du récipient selon l'invention. The figure of the appended drawing schematically represents an embodiment of the container according to the invention.
Le récipient est constitué par un corps 1, un couvercle blindé 2 et un couvercle amortisseur de chocs 3. The container consists of a body 1, a shielded cover 2 and a shock absorbing cover 3.
Un des deux raccords de branchement 4 débouche sur la face frontale du volume intérieur du récipient 9. Le deuxième raccord de branchement 5 est également placé dans le couvercle blindé 2, et il est en communication avec une conduite de liaison 6, encastrée dans le corps de récipient 1., et qui conduit au point le plus profond du volume intérieur du récipient 9, leur jonction étant rendue étanche vismà vis du volume intérieur 9 au moyen d'une garniture 7. Les raccords de branchement 4 et 5 peusent- etre munis de soupapes 8, de raccords instantanés ou d'autres éléments d'obturation0 One of the two connection fittings 4 opens onto the front face of the interior volume of the container 9. The second connection connection 5 is also placed in the shielded cover 2, and it is in communication with a connection pipe 6, embedded in the body container 1., and which leads to the deepest point of the interior volume of the container 9, their junction being sealed vis-à-vis the interior volume 9 by means of a gasket 7. The connection fittings 4 and 5 can be provided valves 8, push-in fittings, or other blanking elements0
