Description

La préscrte invention a essentiellement pour objet un dispositif pour l'installation d'un bloc formant réacteur nucléaire dans un navire.The main object of the present invention is a device for installing a block forming a nuclear reactor in a ship.

Jusqu'à récemment, les réacteurs nucléaires étaient construits directement à l'intérieur des navires, le montage s'effectuant, élément par élément, en utilisant les engins de levage habituels des chantiers de construction.Until recently, nuclear reactors were built directly inside ships, assembly being carried out, element by element, using the usual lifting devices on construction sites.

Certains des éléments constituaient des masses indivisibles de plusieurs centaines de tonnes. Il en résulte que l'on ne pouvait, pratiquement, envisager la construction d'un navire à propulsion nucléaire, que dans les quelques chantiers disposant de moyens de levage exceptionnellement puissants.Some of the elements constituted indivisible masses of several hundred tonnes. As a result, one could, practically, envisage the construction of a nuclear powered ship, only in the few shipyards having exceptionally powerful lifting means.

En outre, une telle construction d'un réacteur nucléaire à bord d'un navire exigeait un très long délai et immobilisait la forme de construction du navire, pendant une période excessive, ce qui entraînait une désorganisation du programme de construction ainsi que des coûts prohibitifs.In addition, such a construction of a nuclear reactor on board a ship required a very long time and immobilized the form of construction of the ship, for an excessive period, which led to disorganization of the construction program as well as prohibitive costs. .

Enfin, les conditions de travail pour le montage du réacteur à bord du navire, notamment pour l'exécution des travaux en propreté nucléaire, ne pouvaient pas être réalisées de manière vraiment satisfaisante.Finally, the working conditions for mounting the reactor on board the ship, in particular for carrying out work in nuclear cleanliness, could not be really satisfactorily achieved.

C'est pourquoi selon un procédé connu il a été proposé de réaliser le navire en deux parties flottantes préfabriquées qui sont ultérieurement assemblées. L'une des parties comporte un logement dans lequel, avant l'assemblage des deux parties, on introduit par translation horizontale un bloc formant réacteur nucléaire. Un tel procédé est décrit dans les demandes de brevets français n° 2 397 322 et anglais n° 2 001 013 qui se correspondent. Compte tenu de l'encombrement et du poids du réacteur nucléaire`(plusieurs milliers de tonnes) la mise en place de celui-ci est une opération complexe.This is why, according to a known method, it has been proposed to make the ship in two prefabricated floating parts which are subsequently assembled. One of the parts comprises a housing in which, before the assembly of the two parts, a block forming a nuclear reactor is introduced by horizontal translation. Such a process is described in French patent applications No. 2,397,322 and English Patent Nos. 2,001,013 which correspond. Given the size and weight of the nuclear reactor (several thousand tonnes), setting it up is a complex operation.

L'invention a pour but de faciliter cette mise en place. Elle a pour objet un dispositif pour l'installation d'un bloc formant réacteur nucléaire dans un navire, ledit navire étant réalisé en au moins deux parties préfabriquées ultérieurement assemblées bout à bout, l'une des parties comportant un logement pour l'introduction dudit bloc avant l'assemblage desdites parties par translation sensiblement horizontale dudit bloc à partir d'une barge, par roulement ou glissement jusque sur un support provisoire situé dans ledit logement caractérisé en ce qu'il comprend des moyens élévateurs composés d'une pluralité de colonnes de guidage du bloc en translation verticale, lesdites colonnes étant pourvues à leur partie supérieure de vérins auxquels ledit bloc est suspendu par des câbles ou analogues et permettant de le soulever, momentanément, pour enlever le support provisoire, puis de le descendre pour le faire reposer à son emplacement définitif dans le logement précité.The invention aims to facilitate this implementation. It relates to a device for installing a block forming a nuclear reactor in a ship, said ship being produced in at least two prefabricated parts subsequently assembled end to end. at the end, one of the parts comprising a housing for the introduction of said block before the assembly of said parts by substantially horizontal translation of said block from a barge, by rolling or sliding onto a temporary support located in said housing characterized in that it comprises lifting means composed of a plurality of columns for guiding the block in vertical translation, said columns being provided at their upper part with jacks to which said block is suspended by cables or the like and making it possible to lift it, momentarily, to remove the temporary support, then to lower it to rest it in its final location in the aforementioned housing.

  • - Les figures 1 à 9 illustrent schématiquement et dans l'ordre, en plan (figures 1, 8 et 9) et en élévation (figures 2 à 7), les différentes étapes du procédé de construction et d'aménagement d'un navire réalisé selon les principes de l'invention,

Other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings, given only by way of example, and in which:
  • - Figures 1 to 9 illustrate schematically and in order, in plan (Figures 1, 8 and 9) and in elevation (Figures 2 to 7), the different stages of the process of construction and layout of a ship made according to the principles of the invention,

Suivant un exemple de réalisation, et en se reportant notamment aux figures 1 à 10, un procédé de construction et d'aménagement d'un navire à propulsion nucléaire conforme à l'invention, comprend les étapes suivantes.According to an exemplary embodiment, and with particular reference to Figures 1 to 10, a method of construction and layout of a nuclear powered ship according to the invention, comprises the following steps.

Dans une forme de construction navale 1, on construit tout d'abord une coque de navire en deux parties, à savoir une partie avant 2 et une partie arrière 3, comme on le voit bien sur la figure 1. Dans la partie avant 2 qui repose dans la forme 1 par l'intermédiaire de tins 4, est ménagé un logment 5 destiné à recevoir un bloc formant réacteur ou chaudière nucléaire 6. Brièvement parlant, ce bloc 6 est constitué par une enveloppe 7 renfermant notamment une cuve et das générateurs de vapeur non représentés, ladite enveloppe 7 et son conteur étant supportés par un socle 8 auquel sont associés des moyens de déplacement non représentés.In a form of shipbuilding 1, a ship's hull is first built in two parts, namely a front part 2 and a rear part 3, as can be seen in FIG. 1. In the front part 2 which rests in form 1 by means of tins 4, is provided a housing 5 intended to receive a block forming a nuclear reactor or boiler 6. Briefly speaking, this block 6 is constituted by an envelope 7 containing in particular a tank and das steam generators not shown, said envelope 7 and its storyteller being supported by a base 8 with which are associated means of displacement not shown.

Comme on le voit clairement sur la figure 2, le bloc réacteur 6 est transporté jusqu'au voisinage et sensiblement au niveau du logemsr au moyen d'une barge 9 introduite dans la forme 1 qui a été préalablement mise en eau. Il convient de noter ici qu'on a disposé dans le logement 5 un support provisoire 10 du bloc réacteur 6, lequel support peut être constitué par exemple par des longrines, cales ou analogues. Ce support 10 est indispensable en ce qu'il permet de rattraper la différence de niveau existant entre le plancher de la barge 9 et le logement 5.As can be clearly seen in FIG. 2, the reactor block 6 is transported to the vicinity and substantially at the level of the logemsr by means of a barge 9 introduced in form 1 which has been previously impounded. It should be noted here that a temporary support 10 of the reactor block 6 has been placed in the housing 5, which support may consist, for example, of stringers, wedges or the like. This support 10 is essential in that it makes it possible to make up for the difference in level existing between the floor of the barge 9 and the housing 5.

Ainsi, on introduira par translation sensiblement horizontale le bloc réacteur 6 dans le logement 5 en le faisant glisser ou rouler sur la barge jusqu'à ce qu'il parvienne sur le support 10 prévu dans le logement 5, comme on le voit bien sur la figure 2.Thus, the reactor block 6 will be introduced by substantially horizontal translation into the housing 5 by sliding or rolling it on the barge until it reaches the support 10 provided in the housing 5, as can be seen on the figure 2.

Cette introduction étant réalisée, on enlève la barge 9 et, comme il apparait sur la figure 3, on-amène, au moyen de grues ou analogues des moyens élévateurs 11 du bloc 6 à proximité immédiate de celui-ci, puis on relie le bloc à ces moyens élévateurs. Plus précisément, les moyens élévateurs 11 qui seront décrits ultérieurement en détail en se reportant aux figures 11 et 12, comprennent essentiellement des colonnes de guidage 12 du bloc 6 en translation verticale, lesdites colonnes étant pourvues à leur partie supérieure de vérins 13 auxquels le bloc 6 peut être suspendu.This introduction being carried out, the barge 9 is removed and, as it appears in FIG. 3, we bring, by means of cranes or the like, elevating means 11 of the block 6 in the immediate vicinity thereof, then connect the block to these lifting means. More specifically, the lifting means 11 which will be described later in detail with reference to FIGS. 11 and 12, essentially comprise guide columns 12 of the block 6 in vertical translation, said columns being provided at their upper part with jacks 13 to which the block 6 can be suspended.

Comme on le voir sur la figure 3, les colonnes de guidage 12 sont enfilées dans le socle 8 du bloc réacteur 6 et prennent appui sur le plancher du logement 5.As can be seen in FIG. 3, the guide columns 12 are threaded into the base 8 of the reactor block 6 and bear on the floor of the housing 5.

Ainsi, par commande des vérins 13, le bloc 6 peut être momentanément soulevé le long des colonnes 12, comme on le voit sur la figure 4, ce qui permet l'évacuation.du support provisoire 10, comme cela est visible sur la figure 5.Thus, by controlling the jacks 13, the block 6 can be temporarily lifted along the columns 12, as seen in FIG. 4, which allows the evacuation of the temporary support 10, as can be seen in FIG. 5 .

Comme on le voit sur la figure 6, le bloc réacteur est ensuite redescendu le long des colonnes de guidage 12, de façon qu'il repose sur son emplacement définitif dans le logement 5. Et, comme il apparait sur la figure 7, on évacue les moyens élévateurs 11 qui avaient été installés provisoirement de la façon décrite ci-avant.As seen in Figure 6, the reactor unit is then lowered along the guide columns 12, so that it rests on its final location in the housing 5. And, as it appears in Figure 7, we evacuate the elevating means 11 which had been temporarily installed as described above.

Le bloc réacteur 6 étant ainsi définitivement en place dans la partie avant du navire, on sort cette dernière de la forme 1 (figure 8), on la retourne, et on la réintroduit dans ladite forme pour réaliser ensuite l'assemblage bout à bout de la partie avant 2 avec la partie arrière 3 comme il apparait sur la figure 9. Et on obtient finalement un navire tel que celui montré sur la figure 10.The reactor block 6 is thus definitively in place in the forward part of the ship, the latter is removed from form 1 (FIG. 8), it is turned over, and it is reintroduced into said form in order to then carry out the end-to-end assembly of the front part 2 with the rear part 3 as it appears in figure 9. And one finally obtains a ship such as that shown in figure 10.

On ne décrira pas ici en détail les diverses opérations de construction et de raboutage les deux parties du navire ni même les travaux annexes exigés par la présence du bloc réacteur et qui peuvent être menés parallèlement aux opérations de construction proprement dites, car, encore une fois, la présente invention vise essentiellement l'introduction du bloc par translation horizontale dans un logement et l'une des parties du navire et son installation dans ce logement.We will not describe here in detail the various construction and splicing operations of the two parts of the ship or even the ancillary works required by the presence of the reactor block and which can be carried out in parallel with the actual construction operations, because, once again , the present invention essentially relates to the introduction of the block by horizontal translation in a housing and one of the parts of the ship and its installation in this housing.

A ce propos, on a montré à plus grande échelle sur les figures 11 et 12 les moyens élévateurs amovibles 11 permettant la translation verticale du bloc réacteur 6 dans son logement pour assurer son installation définitive.In this regard, we have shown on a larger scale in Figures 11 and 12 the removable lifting means 11 allowing the vertical translation of the reactor block 6 in its housing to ensure its final installation.

Suivant l'exemple de réalisation représenté sur ces figures, ces moyens élévateurs sont au nombre de quatre et comportent par conséquent quatre colonnes de guidage 12 qui sont enfilées dans des ouvertures traversantes 14 ménagées aux quatre coins du socle 8 du bloc réacteur 6. Comme on le voit bien sur les figures 11 et 12, les colonnes 12 sont, à leur partie supérieure, solidaires d'une plate-forme 15 qui supporte les vérins 13 dont on a montré schématiquement en 13a les corps, et en 13b les groupes hydrauliques.According to the embodiment shown in these figures, these lifting means are four in number and therefore comprise four guide columns 12 which are threaded through through openings 14 formed at the four corners of the base 8 of the reactor block 6. As we clearly seen in Figures 11 and 12, the columns 12 are, at their upper part, integral with a platform 15 which supports the cylinders 13 which have been shown schematically in 13a the bodies, and in 13b the hydraulic groups.

Ces vérins 13 sont reliés au bloc réacteur 6, et plus précisément au socle 8, par des câbles ou analogues 16 ancrés en 17 au socle, comme on le voit mieux sur la figure 12.These jacks 13 are connected to the reactor block 6, and more precisely to the base 8, by cables or the like 16 anchored at 17 to the base, as can be seen better in FIG. 12.

Les câbles peuvent être constitués par une pluralité de segments vissés comportant une tête à l'une de leurs extrémités et passant au travers des corps de vérins 13a d'une manière connue en soi. Ainsi, de tels câbles permettent avantageusement le soulèvement ou la descente du bloc réacteur 6 par étapes successives ou pas à pas.The cables may consist of a plurality of screwed segments having a head at one of their ends and passing through the bodies of jacks 13a in a manner known per se. Thus, such cables advantageously allow the lifting or lowering of the reactor block 6 in successive or stepwise steps.

On a montré en 18 sur la figure 12 une passerelle protégeant l'opérateur qui ainsi peut travailler en toute sécurité au voisinage des vérins 13. Enfin, on a prévu selon l'invention, et comme il apparait sur la figure 11, des passerelles de liaison 19 entre les quatre moyens élévateurs 11.We have shown at 18 in Figure 12 a gateway protecting the operator who can thus work safely in the vicinity jacks 13. Finally, provision is made according to the invention, and as it appears in FIG. 11, for connecting bridges 19 between the four lifting means 11.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.

C'est ainsi qu'il est parfaitement possible d'appliquer les principes de l'invention, sans sortir du cadre de celle-ci, en adoptant une séquence de construction du navire autre que celle qui a été décrite ci-avant. Il est également possible d'appliquer l'invention à la construction d'une centrale nucléaire sur barge.Thus it is perfectly possible to apply the principles of the invention, without departing from the scope thereof, by adopting a sequence of construction of the ship other than that which has been described above. It is also possible to apply the invention to the construction of a nuclear power plant on a barge.

Par ailleurs, on peut très bien, sans sortir du cadre de l'invention introduire le bloc réacteur latéralement dans un navire en construction dans une forme ou sur une cale de chantier naval.Furthermore, one can very well, without departing from the scope of the invention, introduce the reactor unit laterally in a ship under construction in a form or on a shipyard hold.

L'invention comprend donc tous les équivalents techniques des moyens décrits ainsi que leurs combinaisons si celles-ci sont effectuées suivant son esprit et mises en oeuvre dans le cadre des revendications qui suivent.The invention therefore includes all the technical equivalents of the means described as well as their combinations if these are carried out according to the spirit and implemented in the context of the claims which follow.
