Description

La présente invention concerne un module sous-marin immergeable de production d'énergie électrique. The present invention relates to an underwater submarine module for producing electrical energy.
Plus particulièrement l'invention se rapporte à un tel module sous-marin immergeable qui comporte des moyens formant réacteur nucléaire et qui présente une forme générale tubulaire allongée.  More particularly, the invention relates to such an immersible submarine module which comprises means forming a nuclear reactor and which has an elongated tubular overall shape.
La demanderesse a déjà proposé un tel module dans le cadre d'un projet connu sous le nom de marque de « FLEXBLUE ».  The applicant has already proposed such a module in the framework of a project known under the brand name of "FLEXBLUE".
Ce projet ambitionne de révolutionner la sûreté nucléaire en proposant un concept de sûreté inégalé basé sur l'utilisation d'une source froide disponible en permanence et de façon illimitée et de systèmes de sauvegarde passifs permettant aux moyens formant réacteur nucléaire de faire face de manière autonome à n'importe quel accident pendant une durée de mission de plusieurs semaines.  This project aims to revolutionize nuclear safety by proposing an unparalleled safety concept based on the use of an unlimited and permanently available cold source and passive backup systems enabling the nuclear reactor means to cope autonomously. to any accident during a mission duration of several weeks.
Ce projet a permis de mettre en avant et de concevoir des moyens de sécurisation du fonctionnement du module en utilisant par exemple l'eau de mer comme source froide de réfrigération passive des moyens formant réacteur, dans la mesure où le module est immergé et entouré d'eau de mer.  This project has made it possible to highlight and design means for securing the operation of the module by using, for example, seawater as a passive cooling source for the reactor means, insofar as the module is immersed and surrounded by water.

En effet ces phases sont pressenties comme étant des phases de vulnérabilité potentielle pour le module car la source froide c'est-à-dire en fait la mer, n'est plus disponible de façon passive.  Indeed, these phases are perceived as phases of potential vulnerability for the module because the cold source, that is to say, the sea, is no longer available passively.
Le but de l'invention est donc de proposer des solutions à ce problème.  The object of the invention is therefore to propose solutions to this problem.
A cet effet, l'invention a pour objet un module sous-marin immergeable de production d'énergie électrique, du type comportant des moyens formant réacteur nucléaire et présentant une forme générale tubulaire allongée, caractérisé en ce qu'il comporte dans sa partie supérieure des moyens formant réservoir externe d'eau froide de refroidissement lorsque le module est hors d'eau.  To this end, the subject of the invention is a submarine submarine module for the production of electrical energy, of the type comprising nuclear reactor means and having a generally elongated tubular shape, characterized in that it comprises in its upper part cold water external reservoir means for cooling when the module is out of water.

- les conduits s'étendent à travers le module entre les parties inférieures et supérieures des moyens formant réservoir.  the ducts extend through the module between the lower and upper parts of the reservoir means.
L'invention sera mieux comprise à l'aide de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lesquels :  The invention will be better understood with the aid of the following description given solely by way of example and with reference to the appended drawings in which:
- la figure 1 représente une vue en section d'un exemple de réalisation d'un module sous-marin selon l'invention ;  - Figure 1 shows a sectional view of an embodiment of an underwater module according to the invention;
- la figure 2 représente une vue de dessus d'un exemple de réalisation d'un tel module sous-marin.  - Figure 2 shows a top view of an exemplary embodiment of such a submarine module.
On a en effet illustré sur ces figures un module sous-marin immergeable de production d'énergie électrique.  In these figures, a submarine underwater module for the production of electrical energy has been illustrated.
Ce module est désigné par la référence générale 1 sur ces figures et comporte par exemple de façon classique les moyens formant réacteur nucléaire, placés dans un compartiment correspondant désigné par exemple par la référence générale 2 sur ces figures.  This module is designated by the general reference 1 in these figures and comprises for example in conventional manner the nuclear reactor means, placed in a corresponding compartment designated for example by the general reference 2 in these figures.
En fait le module sous-marin présente par exemple une forme générale tubulaire allongée comme celle illustrée sur ces figures et désignée par la référence générale 3.  In fact the submarine module has for example an elongated tubular overall shape such as that illustrated in these figures and designated by the general reference 3.
Cette portion tubulaire allongée du module étant associée à des moyens de piétement désignés par la référence générale 4, permettant d'assurer le support de celui-ci par exemple sur le fond ou en immersion entre deux eaux, de façon générale dans l'eau. Pour résoudre les différents problèmes évoqués précédemment à propos de la sûreté de ce module lorsqu'il est par exemple en émersion, c'est-à-dire hors de l'eau, le module 1 comporte dans sa partie supérieure des moyens formant réservoir externe d'eau froide de refroidissement utilisable en particulier lorsque le module est hors d'eau. This elongated tubular portion of the module being associated with base means designated by the general reference 4, to ensure the support thereof for example on the bottom or in immersion between two waters, generally in water. To solve the various problems mentioned above about the safety of this module when it is for example in emersion, that is to say out of the water, the module 1 has in its upper part means forming an external reservoir coolant cooling water usable especially when the module is out of water.
Ces moyens formant réservoir externe d'eau sont désignés par la référence générale 5 sur ces figures et comprennent toute forme de moyens permettant de constituer un réservoir d'eau.  These external water reservoir means are designated by the general reference 5 in these figures and include any form of means for constituting a water tank.
Dans l'exemple de réalisation illustré, les moyens formant réservoir externe d'eau froide sont adaptés pour s'étendre au moins sur une partie de la longueur de ce module au-dessus des moyens formant réacteur nucléaire, comme cela est illustré plus clairement sur la figure 2.  In the exemplary embodiment illustrated, the cold water external reservoir means are adapted to extend over at least a part of the length of this module above the nuclear reactor means, as is more clearly illustrated in FIG. Figure 2.
En fait différents modes de réalisation de ces moyens formant réservoir externe d'eau peuvent être envisagés.  In fact different embodiments of these external water reservoir means can be envisaged.
Ceux-ci peuvent en effet être fixés à demeure sur le reste du module par exemple par soudage ou être associables à celui-ci de façon détachable par exemple par accrochage....  These can indeed be fixed permanently on the rest of the module for example by welding or be associated with it in a detachable manner for example by hooking ....
Ainsi par exemple et comme cela est illustré, ces moyens formant réservoir sont formés par exemple par un assemblage de plaques périphériques dressées et fixées sur la surface extérieure du module de manière à délimiter les bords de ce réservoir et dont le fond est alors formé par la paroi du module.  For example, and as illustrated, these reservoir means are formed for example by an assembly of peripheral plates erected and fixed on the outer surface of the module so as to define the edges of this reservoir and whose bottom is then formed by the wall of the module.
Ainsi par exemple sur ces figures, ces moyens formant réservoir comportent par exemple des plaques latérales 6 et 7, fixées à demeure sur le module.  Thus for example in these figures, these reservoir means comprise for example side plates 6 and 7, fixed permanently on the module.
Par exemple les plaques peuvent être soudées.  For example the plates can be welded.
Il va de soi que ces plaques peuvent également être dressées et accrochées de façon démontable sur la surface extérieure du module de manière à délimiter les bords du réservoir.  It goes without saying that these plates can also be erected and removably hooked on the outer surface of the module so as to define the edges of the tank.
Comme cela est également illustré, ces moyens formant réservoir 5 peuvent comporter des plaques intermédiaires de manière à délimiter des compartiments dans les moyens formant réservoir 5.  As also illustrated, these reservoir means 5 may comprise intermediate plates so as to delimit compartments in the reservoir means 5.
Ces compartiments sont par exemple conçus pour éviter les effets de carène liquide et communiquent entre eux. De nombreux modes de réalisation peuvent bien entendu être envisagés.  These compartments are for example designed to avoid the effects of free surface and communicate with each other. Many embodiments can of course be considered.
Ainsi par exemple, trois plaques intermédiaires désignées par les références 8, 9 et 10 sont illustrées sur cette figure 1 , ces plaques intermédiaires permettant de délimiter avec les plaques externes, des compartiments respectivement 1 1 , 12, 13 et 14 dans les moyens formant réservoir. Les moyens formant réservoir d'eau froide peuvent alors être associés à des échangeurs de chaleur des moyens formant réacteur nucléaire. For example, three intermediate plates designated by the references 8, 9 and 10 are illustrated in this FIG. 1, these intermediate plates making it possible to delimit, with the external plates, respectively compartments 1 1, 12, 13 and 14 in the reservoir means. . The cold water reservoir means can then be associated with heat exchangers of the nuclear reactor means.
Ces échangeurs sont illustrés sur ces figures et en particulier sur la figure 1 et sont désignés par les références 15 et 16.  These exchangers are illustrated in these figures and in particular in Figure 1 and are designated by references 15 and 16.
En fait ces échangeurs de chaleur peuvent être disposés dans des conduits respectivement 17 et 18 s'étendant entre les parties inférieure et supérieure des moyens formant réservoir 5 comme cela est illustré.  In fact, these heat exchangers can be arranged in ducts 17 and 18 respectively extending between the lower and upper portions of the reservoir means 5 as illustrated.
De même ces conduits peuvent s'étendre comme cela est illustré à travers le module entre les parties inférieure et supérieure des moyens formant réservoir 5.  Similarly, these ducts may extend as illustrated through the module between the lower and upper parts of the reservoir means 5.
Bien entendu d'autres dispositions et modes de réalisation peuvent être envisagés.  Of course other arrangements and embodiments can be envisaged.
Ainsi par exemple, ces échangeurs de chaleur (ou condenseurs de vapeur) peuvent simplement être disposés directement dans les moyens formant réservoir, c'est-à-dire sans utiliser les conduits s'étendant entre les parties inférieures et supérieures des moyens formant réservoir.  For example, these heat exchangers (or steam condensers) can simply be arranged directly in the reservoir means, i.e. without using the conduits extending between the lower and upper portions of the reservoir means.
Ceci permet alors d'assurer une circulation d'eau à travers les échangeurs afin de refroidir le réacteur qui est placé à une élévation plus basse.  This then ensures a flow of water through the exchangers to cool the reactor which is placed at a lower elevation.
On conçoit alors qu'une telle structure présente un certain nombre d'avantages dans la mesure où ces moyens formant réservoir constituent une source d'eau de réfrigération passive du réacteur lorsque celui-ci est hors d'eau par exemple pour ou lors d'opérations de transport, d'entretien, etc ..  It will be understood that such a structure has a certain number of advantages insofar as these reservoir means constitute a source of passive cooling water for the reactor when it is out of water, for example for or during transport operations, maintenance, etc.
Un tel système de réfrigération est appelé passif dans la mesure où il ne nécessite aucune source d'alimentation en énergie.  Such a refrigeration system is called passive since it does not require any source of power supply.
En fait le système selon l'invention propose de transporter une partie de la source froide avec le module lorsque celui-ci est en hors d'eau.  In fact the system according to the invention proposes to transport part of the cold source with the module when the latter is out of water.
Cette forteresse froide est alors située par exemple au-dessus du compartiment réacteur c'est-à-dire de l'enceinte de confinement et des condenseurs de secours. Ces derniers sont noyés dans l'eau du réservoir, ils peuvent donc continuer à fonctionner de la même manière que sous l'eau et échanger leur chaleur avec l'eau du réservoir.  This cold fortress is then located for example above the reactor compartment that is to say the containment and emergency condensers. These are embedded in the water tank, they can continue to operate in the same way as under water and exchange their heat with the water tank.
Le réservoir est alors également extrêmement facile à réalimenter en tant que de besoin en eau de remplacement et de réapprovisionnement car il peut être ouvert dans sa partie supérieure.  The tank is then also extremely easy to replenish as needed replacement water and replenishment because it can be opened in its upper part.
Il va de soi bien entendu que d'autres modes de réalisation encore peuvent être envisagés.  It goes without saying of course that other embodiments can be envisaged.
