Description
Verfahren und Einrichtung zum Deborieren von Primärkühlmittel einer wassergekühlten Kernreaktoranlage Method and device for deborating primary coolant in a water-cooled nuclear reactor plant
In wassergekühlten Kernreaktoranlage wird Je nach Leistungsund Abbrandzustand des Reaktors Borsäure in das Primärkühlmittel eingespeist oder daraus entzogen. Beim Borentzug, der sogenannten Deborierung, wird bisher Primärkühlmittel aus dem Kreislauf aus- und Deionat (vollentsalztes Wasser) eingespeist. Zur Lagerung des Deionats sind mehrere Behälter erforderlich. Das ausgespeiste Primärkühlmittel wird mittels Verdampferanlagen in Wasser und Borsäurekonzentrat getrennt und in Behältern gelagert. (Thiemig-Taschenbücher, Band 51 "Druckwasserreaktoren für Kernkraftwerke" Seite 177).In a water-cooled nuclear reactor plant, depending on the power and Burned condition of the reactor Boric acid fed into the primary coolant or withdrawn from it. With boron withdrawal, the so-called deboration, primary coolant has so far been removed from the circuit and deionized water (fully demineralized water) is fed in. Several containers are required to store the deionized water. The discharged primary coolant is by means of Evaporator systems separated into water and boric acid concentrate and stored in containers. (Thiemig paperbacks, volume 51 "Pressurized water reactors for nuclear power plants" page 177).
Der Einsatz von Verdampferanlagen erfordert einen hohen Wärmebedarf. Weiterhin ist ein großes Speichervolumen für Deionat erforderlich um eine bestimmte Lastwechselflexibilität sicherzustellen. 'The use of evaporator systems requires a high level of heat. Furthermore, there is a large storage volume for Deionized water required to ensure a certain load change flexibility. '
Es ist die Aufgabe der Erfindung ein Verfahren und eine Einrichtung zur Deborierung von Primärkühlmittel zu finden bei dem nur eine geringe Lagerkapazität für Deionat und kein Verdampfen erforderlich ist.It is the object of the invention to find a method and a device for deborating primary coolant only a small storage capacity for deionized water and no evaporation is required.
Gelöst wird die Aufgabe erfindungsgemäß dadurch, daß ein Teilstrom des Primärkühlmittels durch eine Umkehr-Osmose-Einheit geleitet wird und daß das dabei abgetrennte vollentsalzte Wasser unmittelbar in die Saugleitung der Volumenregelpumpe eingespeist wird.The object is achieved according to the invention in that a partial flow of the primary coolant is passed through a reverse osmosis unit and that the completely demineralized Water is fed directly into the suction line of the volume control pump.

Durch die Verwendung der aus der chemischen Verfahrenstechnik an sich bekannten Umkehr-Osmose zur Erzeugung des vollentsalzten Wassers entfällt eine aufwendige Verdampferanlage und die dazu notwendigen Lagerbehälter. Das vollentsalzte Wasser wird auf einfache, schnelle und kostensparende Weise aus dem ausgespeisten Primärkühlmittel gewonnen und kann daher unmittelbar zur Verdünnung und somit zur Herabsetzung des Borgehaltes im Primärkreislauf verwendet werden.By using the reverse osmosis, known per se from chemical process engineering, to generate the fully desalinated Water, there is no need for a complex evaporator system and the storage containers required for this. The fully demineralized water is on simple, fast and cost-saving way from the fed out Primary coolant obtained and can therefore be used directly for dilution and thus to reduce the boron content in the Primary circuit can be used.
Der Druck des Teilstromes wird in vorteilhafter Weise auf den Betriebsdruck der Umkehr-Osmose-Einheit eingestellt. Mit dieser Maßnahme wird der Einsatz einer Druckerhöhungspumpe vermieden.The pressure of the partial flow is advantageously set to the operating pressure of the reverse osmosis unit. With this Measure, the use of a booster pump is avoided.
Die Einrichtung zur Durchführung des Verfahrens ist dadurch
gekennzeichnet, daß von der Bypassleitung ein zur Umkehr-Osmose-Einheit hinführender Strang abzweigt, daß im Strang und
in der Bypassleitung eine Ventilgruppe angeordnet ist und daß der Umkehr-Osmose-Einheit ein Feststoffilter vorgeschaltet ist.
Durch diese Anordrung ist es auf einfache V/eise möglich, die Durchflußmenge und den Druck des zur Primärkühlmittelreinigungsanlage
und zur Umkehr-Osmose-Einheit fließenden PrimärkühlmittelThe device for carrying out the process is thereby
characterized in that a branch leading to the reverse osmosis unit branches off from the bypass line, that a valve group is arranged in the branch and in the bypass line and that the reverse osmosis unit is preceded by a solids filter. This arrangement makes it possible in a simple manner to determine the flow rate and the pressure of the primary coolant flowing to the primary coolant cleaning system and to the reverse osmosis unit

ausreichendem Maße vorgereinigt.current to adapt to the requirements of the reactor plant. With the solids filter, the primary coolant to be deborated is in
sufficiently pre-cleaned.
Das erfindungsgemäße Verfahren und die Einrichtung zur Durchführung des Verfahrens wird anhand der schematischen Zeichnung beschrieben.The method according to the invention and the device for carrying it out the method is described with reference to the schematic drawing.

Über die Saugleitung 4 der Volumenregelpumpe 5 die praktisch eine Weiterführung der Bypassleitung 1 ist, gelangt das gereinigte Primärkühlmittel wieder in den Primärkreislauf der Reaktoranlage. Saugseitig der Volumenregelpumpe ist ein Volumenausgleichsbehälter 5 und druckseitig eine Armatur 7 zur Einspeiseregelung vorgesehen. Ein ebenfalls druckseitig angeordneter Abzweig 8 mit einer Regelarmatur 9 dient zur Sperrwasserversorgung der Primärkreislaufpumpen. In Durchflußrichtung gesehen zweigt vor der Ventilgruppe 3 ein Strang 10 ab der ebenfalls mit einer Ventilgruppe 3a zur Durchflußregelung und Druckreduzierung ausgestattet ist. Je nach der Stellung der Ventilgruppe 3»3a strömen unterschiedliche Mengen durch die Bypassleitung 1 und/oder den Strang 10. Mit der Ventilgruppe 3a wird der Druck in dem Strang 10 auf dem Betriebsdruck der Umkehr-Osmose-Einheit gehalten. Das in dem Strang 10 fließende Primärkühlmittel wird in einem Feststofffilter 11 vorgereinigt und durchströmt dann eine Umkehr-Osmose-Einheit 12. Beim Durchströmen der Umkehr-Osmose-Einheit fällt als Permeat volle.itsalztes Wasser an das über die Leitung 13 in den saugseitigen Bereich der Volumenregelpumpe 5 gelangt. Aufkonzentrierte Borsäure verläßt die Umkehr-Osmose-EinheitThis arrives via the suction line 4 of the volume control pump 5, which is practically a continuation of the bypass line 1 cleaned primary coolant back into the primary circuit of the Reactor plant. On the suction side of the volume control pump is a volume compensation tank 5 and on the pressure side is a valve 7 for Feed-in regulation provided. A branch 8, also arranged on the pressure side, with a control valve 9 is used for Sealing water supply to the primary circuit pumps. Seen in the direction of flow, a branch 10 branches off in front of the valve group 3 from which is also equipped with a valve group 3a for flow control and pressure reduction. Depending on the Position of the valve group 3 »3a, different amounts flow through the bypass line 1 and / or the line 10. With the Valve group 3a, the pressure in the line 10 is kept at the operating pressure of the reverse osmosis unit. That in that Strand 10 flowing primary coolant is in a solids filter 11 pre-cleaned and then flows through a reverse osmosis unit 12. When flowing through the reverse osmosis unit falls full.itsalztes water as permeate which reaches the suction-side area of the volume control pump 5 via line 13. Concentrated boric acid leaves the reverse osmosis unit
