ASSEMBLAGES COMBUSTIBLES NUCLEAIRESNUCLEAR FUEL ASSEMBLIES
DOMAINE TECHNIQUETECHNICAL AREA
L'invention concerne un emballage ou conteneur de transport ou stockage d'assemblages combustibles nucléaires, ledit emballage comprenant un corps métallique forgé, en général en acier forgé, délimitant une cavité dans laquelle sont introduits les assemblages.The invention relates to a packaging or container for transporting or storing nuclear fuel assemblies, said packaging comprising a forged metal body, generally made of forged steel, delimiting a cavity into which the assemblies are introduced.
L'invention concerne également le moyen de le réaliser.The invention also relates to the means of achieving it.
ETAT DE LA TECHNIQUE ET PROBLEME POSESTATE OF THE ART AND PROBLEM POSED
Les assemblages combustibles nucléaires sont généralement de forme prismatique ou cylindrique avec souvent une section carrée (ex. PWR, BWR, ...), parfois une section hexagonale (VVER,...), parfois une section circulaire (CANDU, RBMK,...).Nuclear fuel assemblies are generally prismatic or cylindrical in shape, often with a square section (eg PWR, BWR, ...), sometimes a hexagonal section (VVER, ...), sometimes a circular section (CANDU, RBMK ,. ..).
Un problème du concepteur d'emballage est de parvenir à loger le maximum d'assemblages dans la cavité de l'emballage tout en respectant les réglementations en vigueur; en particulier l'emballage doit présenter :A problem for the packaging designer is to manage to accommodate the maximum number of assemblies in the cavity of the packaging while respecting the regulations in force; in particular the packaging must have:
- un blindage suffisant contre les radiations des matières radioactives contenues;- sufficient shielding against radiation from the radioactive material contained;
- une résistance mécanique et une étanchéité suffisantes pour assurer le confinement des matières radioactives contenues, y compris en conditions accidentelles;- sufficient mechanical strength and tightness to ensure the containment of the radioactive material contained, including in accident conditions;
- une conductivité thermique suffisante pour que la chaleur éventuellement dégagée par les assemblages radioactifs logés dans la cavité puissent être évacuée vers le corps de l'emballage de façon à en limiter la température atteinte.- a sufficient thermal conductivity so that the heat possibly released by the radioactive assemblies housed in the cavity can be evacuated towards the body of the packaging so as to limit the temperature reached.
Par ailleurs, le poids de l'emballage et son encombrement doivent être limités pour être compatibles avec les équipements des installations à desservir (réacteurs, installations de stockage intermédiaire, usines de retraitement, moyen de transport).In addition, the weight of the packaging and its size must be limited to be compatible with the equipment of the installations to serve (reactors, intermediate storage facilities, reprocessing plants, means of transport).
En particulier, il est avantageux de disposer d'un emballage ayant une cavité dont la section droite a une forme ajustée à celle des assemblages combustibles et ayant un corps de forme telle que le stockage côte à côte de plusieurs emballages prenne le moins de place possible.In particular, it is advantageous to have a package having a cavity whose cross section has a shape adjusted to that of the fuel assemblies and having a shaped body such that the storage side by side of several packages takes up as little space as possible. .
De ce point de vue, l'utilisation d'emballage ayant par exemple une cavité à section circulaire pour y loger des assemblages combustibles à section carrée n'est pas totalement satisfaisante. De même, des emballages dont la surface extérieure du corps a une section droite circulaire ne sont pas toujours satisfaisants.From this point of view, the use of packaging having, for example, a cavity with a circular section for accommodating combustible assemblies with a square section is not entirely satisfactory. Likewise, packages whose external surface of the body has a circular cross section are not always satisfactory.
II existe plusieurs technologies pour la construction d'emballages métalliques : emballages en fonte de fer (coulée), emballages multicouches acier/acier (roulés-soudés), emballages au plomb (plomb coulé entre deux enceintes en acier roulé-soudé), emballages en acier forgé (virole forgée puis usinée au tour) .There are several technologies for the construction of metallic packaging: cast iron packaging (casting), multilayer steel / steel packaging (rolled-welded), lead packaging (lead cast between two enclosures in rolled-welded steel), packaging in forged steel (forged ferrule then lathe machined).
Ces technologies qui reposent sur des procédés de révolution autour d'un axe (roulage de tôles, forgeage de viroles, usinage au tour, etc..) sont peu favorables à la mise en oeuvre de l'idée précédente de compacité de stockage.These technologies which are based on processes of revolution around an axis (rolling of sheets, forging of ferrules, lathe machining, etc.) are not very favorable to the implementation of the preceding idea of compactness of storage.
D'autre part, les technologies qui reposent sur des procédés tels que la coulée permettent en principe d'obtenir des emballages à section non circulaire, mais pour des raisons liées à la santé du matériau coulé, il est souvent préférable d'utiliser des formes d'emballage circulaire qui permettent de mieux contrôler les conditions de refroidissement.On the other hand, technologies based on processes such as casting in principle make it possible to obtain packages with a non-circular section, but for reasons related to the health of the material being cast, it is often preferable to use shapes. circular packaging to better control the cooling conditions.
Ainsi, la demanderesse a cherché à mettre au point des emballages présentant un gain de poids et d'encombrement par rapport à la quantité d'assemblages combustibles qui y sont logés, tout en satisfaisant les conditions de blindage, de conductivité thermique et de tenue mécanique requises. DESCRIPTION DE L'INVENTIONThus, the Applicant has sought to develop packaging having a saving in weight and size compared to the quantity of fuel assemblies housed therein, while satisfying the conditions of shielding, thermal conductivity and mechanical strength. required. DESCRIPTION OF THE INVENTION
L'invention est un emballage pour assemblages combustibles nucléaires tel que décrit dans les revendications attenantes. L'emballage selon l'invention a donc un corps cylindrique métallique dont la section droite n'est pas circulaire. Autrement dit ladite section droite a l'aspect d'une couronne dont les périmètres intérieur et extérieur n'ont pas la forme d'un cercle mais contiennent généralement des segments de droites; les périmètres peuvent par exemple avoir la forme de carrés, ou d'autres polygones réguliers, concentriques dont lesangles peuvent être arrondis.The invention is a package for nuclear fuel assemblies as described in the appended claims. The packaging according to the invention therefore has a metallic cylindrical body whose cross section is not circular. In other words, said cross section has the appearance of a crown, the interior and exterior perimeters of which do not have the shape of a circle but generally contain segments of straight lines; the perimeters can for example have the shape of squares, or other regular, concentric polygons whose angles can be rounded.
Ceci vient du fait qu'à partir d'une virole métallique épaisse ayant une section droite de forme circulaire et délimitant une cavité intérieure où seront logés les assemblages, on a pratiqué un ou des méplats sur toute la hauteur de la paroi extérieure de la virole par rectifiage et/ou on a introduit des lunules, à l'intérieur de la cavité, qui épousent la forme de sa paroi intérieure et y sont fixées. Ces lunules ont une section droite qui est formée d'une part d'un arc de cercle de même diamètre que celui de la paroi intérieure de la cavité et d'autre part d'une corde qui sous-tend l'arc de cercle et qui correspond donc à une partie plane de la paroi intérieure de la cavitéThis is due to the fact that, starting from a thick metallic ferrule having a cross-section of circular shape and delimiting an interior cavity where the assemblies will be housed, one or more flats have been made over the entire height of the exterior wall of the ferrule. by grinding and / or lunules have been introduced inside the cavity which conform to the shape of its inner wall and are fixed there. These lunules have a cross section which is formed on the one hand by an arc of a circle of the same diameter as that of the interior wall of the cavity and on the other hand by a cord which underlies the arc of circle and which therefore corresponds to a flat part of the interior wall of the cavity
L'épaisseur du corps cylindrique métallique à section droite non circulaire selon l'invention est en tous points suffisante pour assurer un blindage conforme aux spécifications. Elle atteint en général plusieurs dizaines de centimètres.The thickness of the metallic cylindrical body with a non-circular cross section according to the invention is sufficient in all respects to ensure shielding in accordance with the specifications. It generally reaches several tens of centimeters.
On voit que la forme de la cavité intérieure peut être adaptée au type d'assemblages combustibles devant y être logés. Ainsi quand par exemple les assemblages ont une section droite carrée, on choisit de préférence une cavité ayant une section droite carrée ou rectangulaire avec généralement des angles arrondis; ceci permet d'accroître son coefficient de remplissage (moins d'espace mort que dans une cavité à section circulaire). En pratiquant des méplats sur la paroi extérieure du corps cylindrique, méplats faisant généralement face aux parties planes de la paroi intérieure, on diminue simultanément le poids et l'encombrement de l'emballage tout en lui conservant un blindage et une résistance mécanique suffisantes; on augmente de plus, grâce à leur forme extérieure, la densité de stockage au m des emballages.It can be seen that the shape of the interior cavity can be adapted to the type of fuel assemblies to be housed there. Thus when, for example, the assemblies have a square cross section, a cavity having a square or rectangular cross section with generally rounded corners is preferably chosen; this increases its filling coefficient (less dead space than in a circular section cavity). By making flats on the outer wall of the cylindrical body, flats generally facing the flat parts of the inner wall, simultaneously reducing the weight and size of the package while maintaining sufficient shielding and mechanical strength; in addition, thanks to their external shape, the storage density per m of the packaging is increased.
La cavité se situant à l'intérieur du corps cylindrique métallique est généralement obturée à ses deux extrémités, l'une d'elles par un fond fixé par exemple par soudage avec ou sans frettage, l'autre par un couvercle amovible.The cavity located inside the metallic cylindrical body is generally closed at its two ends, one of them by a bottom fixed for example by welding with or without shrinking, the other by a removable cover.
La virole de départ à section circulaire devant être modifiée pour aboutir au corps cylindrique selon l'invention est généralement à base d'acier forgé.The starting ferrule with circular section to be modified to end up with the cylindrical body according to the invention is generally based on forged steel.
Par voie de conséquence le corps cylindrique de l'emballage selon l'invention est de même nature.Consequently, the cylindrical body of the packaging according to the invention is of the same nature.
La figure 1 illustre un emballage selon l'invention et en représente la coupe transversale.Figure 1 illustrates a package according to the invention and shows the cross section.
La figure 2 illustre un détail du mode de fixation par vis d'une lunule sur la paroi interne du corps cylindrique.FIG. 2 illustrates a detail of the method of fixing by screw of a lunula on the internal wall of the cylindrical body.
Sur la figure 1 :In figure 1:
- en (1) on voit le corps cylindrique métallique de l'emballage à section non circulaire;- In (1) we see the metallic cylindrical body of the packaging with a non-circular section;
- (2) représente la cavité intérieure de l'emballage;- (2) represents the interior cavity of the packaging;
- (3) représente la virole épaisse de départ, sur la paroi extérieure 4 de laquelle ont été dressés des méplats (5) par rectifiage- (3) represents the thick starting ferrule, on the outer wall 4 of which were drawn flats (5) by grinding
- (6) représente la paroi intérieure de la virole sur laquelle ont été fixées des lunules (7) dont le périmètre de la section droite comporte essentiellement un arc de cercle (8), de même diamètre que celui de la cavité interne (2) limitée par la paroi interne (6), l'arc de cercle (8) étant sous-tendu par une corde (9) qui représente donc une face plane de la cavité interne (2) - On voit donc que le corps cylindrique de l'emballage, comportant les méplats (5) et les lunules (7) sous-tendu par leurs cordes (9) parallèles aux méplats (5), a bien une section droite non circulaire.- (6) represents the inner wall of the ferrule on which lunules (7) have been fixed, the perimeter of the cross section of which essentially comprises an arc of a circle (8), of the same diameter as that of the internal cavity (2) limited by the internal wall (6), the arc of a circle (8) being subtended by a cord (9) which therefore represents a flat face of the internal cavity (2) - It can therefore be seen that the cylindrical body of the packaging, comprising the flats (5) and the lunulas (7) subtended by their strings (9) parallel to the flats (5), does indeed have a non-circular cross section.
Les dimensions des méplats et des lunules peuvent varier et être adaptées aux assemblages à ranger dans la cavité 2, en veillant toutefois à ce que les épaisseurs du corps cylindrique 1 répondent aux exigences de blindage et de résistance mécanique.The dimensions of the flats and the lunules can vary and be adapted to the assemblies to be stored in the cavity 2, while ensuring that the thicknesses of the cylindrical body 1 meet the requirements for shielding and mechanical strength.
Sur la figure 2 on voit le corps de la virole (3) et la lunule (7) fixée sur la paroi intérieure 6 de la virole à l'aide de vis (10). In Figure 2 we see the body of the ferrule (3) and the lunula (7) fixed to the inner wall 6 of the ferrule using screws (10).
