Definitions

  • the present invention relates to a method and devices for carrying out exchanges in storage basins for radioactive products.
  • radioactive substances for example waste or contaminated products
  • the water in these basins must undergo exchanges which are either thermal exchanges or ionic exchanges.
  • FIG. 5 on page 47 of said article represents an exchanger immersed in liquid sodium filling the vessel of the reactor core.
  • This exchanger is traversed by liquid sodium of external origin in order to extract calories from the reactor core. It will be noted that this exchanger does not include a pump for setting in motion the sodium in the tank through the exchanger.
  • the present invention therefore relates to a system for carrying out heat and / or ionic exchanges and / or filtrations on the water of a storage tank for radioactive substances, system comprising at least one exchange unit and characterized in that it comprises a base resting on the bottom of the basin and comprising means allowing the water to leave the basin through said bare, and a flaring enabling it to receive a cartridge containing the exchange and / or filtration device, this cartridge comprising at its lower part means for adapting to said flaring of said base and at its upper part a flaring for receiving a castle for circulating the water of the swimming pool and the circulation castle comprising at its base a device adapting to said flaring of said cartridge and a low or medium pressure pump actuated by a motor, the entire exchange unit, with the exception of said motor, being immersed in the water of the storage tank of radioactive substances.
  • It also relates to a method for carrying out, on the water of a storage tank for radioactive substances, the thermal and / or ionic exchanges and / or the filtrations necessary for the proper functioning of said tank, process in which at least one of said ones is used exchange units.
  • exchange unit we mean a group (or element) individualized, independent and, therefore, interchangeable.
  • the exchange unit will consist of a device ensuring the circulation of water from the basin at low or medium pressure and of one or more supplied heat exchange elements, d firstly, in basin water by said device ensuring the circulation of the basin water and, secondly, by an external element ensuring a circulation of a cooling fluid.
  • exchange we mean all operations of a physical or chemical nature involving a transfer between the water (or the materials present in the water) of the basins and an element responsible for ensuring a certain treatment of this water. It can be a heat exchange where calories are exchanged, through a wall, between water and an external fluid; it can be a purification of water by filtration; it can be an exchange between ions contained in water and ions of an ion exchanger.
  • the exchange part 4 can simply be constituted by a filter whose object is to physically purify the water in the basin; it can also be a device comprising one or more beds of ion exchange resins.
  • exchange devices should be used in which the pressure drop in the basin water will be low enough for the supply of these devices to be ensured by low or medium pressure circulation devices.
  • said bed may advantageously have the shape of a basket in the shape of an O-ring containing the resin in the form of particles of suitable particle size. , said basket being crossed from the periphery towards its center by the water of the basin.
  • thermo and / or ionic exchanges (with or without filtration), which in particular allows said ionic exchanges to be effected at a controlled and adequate temperature.

1. System zur Durchführung eines Wärme-und/oder lonenaustausches und/oder einer Filtration des Wassers eines Lagerbeckens für radioaktive Substanzen, welches System zumindest eine Austauschereinheit umfaßt, dadurch gekennzeichnet, daß es eine am Boden des Beckens ruhende Basis (3) mit Mitteln zur Ermöglichung des Austritts des Beckenwassers durch die Basis und einer trichterförmigen Erweiterung zur Aufnahme einer die Austauscher- und/oder Filtereinrichtung enthaltenden Hülse, welche Hülse an ihrem unteren Teil Mittel zum Anpassen an die trichterförmige Erweiterung der Basis und an ihrem oberen Teil eine trichterförmige Erweiterung zur Aufnahme eines Zirkulationsturms (6) für das Beckenwasser umfaßt, welcher Zirkulationsturm (6) an seiner Basis eine zur trichterförmigen Erweiterung der Hülse (4) passende Einrichtung und eine von einem Motor (7) betriebene Nieder- oder Mitteldruckpumpe (8) umfaßt, wobei die gesamte Austauschereinheit mit Ausnahme des Motors (7) im Wasser des Lagerbeckens für radioaktive Substanzen eingetaucht ist.
2. System nach Anspruch 1, dadurch gekennzeichnet, daß es zur Durchführung eines Wärmeaustausches verwendet wird und die Austauschereinrichtung durch einen dekannten Austauscher gebildet ist, in welchem einerseits das Beckenwasser und anderseits ein von außerhalb des Beckens kommendes Kühlwasser zirkulieren.
3. System nach Anspruch 1, dadurch gekennzeichnet, daß es zur Durchführung eines lonenaustausches verwendet wird und die Austauschereinrichtung durch ein Austauschbett in Form eines den Austauscher enthaltenden ringförmigen Korbes gebildet ist, der vom Umfang zu seinem Mittelpunkt hin vom Beckenwasser durchflossen ist.
4. Verfahren zur Durchführung des für das gute Funktionieren eines Lagerbeckens für radioaktive Substanzen notwendigen Wärme-und/oder lonenaustausches und/oder der Filtration des Wassers dieses Beckens, dadurch gekennzeichnet, daß zumindest ein System nach einem der Ansprüche 1 bis 3 verwendet wird.
