Abstract

In a nuclear reactor plant, it is necessary for the purpose of conditioning the primary coolant for hydrogen to be added to it. In order to reduce the risk of an explosion of oxyhydrogen gas, the supply line (16) is connected directly to a device (17) for the electrolytic production of hydrogen. The device is located in this arrangement in the vicinity of the site where the hydrogen is used. <IMAGE>

Description

Anordnung zur Versorgung einer wasserZekühlten Kern-Arrangement for the supply of a water-cooled core

reaktoranlage mit Wasserstoff In wassergekühlten Kernreaktoranlagen wird zur Konditionierung des Hauptkühlmittels demselben über das Volumenausgleichssystem Wasserstoff zugeführt. Der dazu benötigte Wasserstoff wird seither in nicht unerheblichen Mengen in Druckgasflaschen gelagert, die über Druckleitungen und eine Druckreduzierstation mit dem Volumenausgleichssystem verbunden sind. Bei der Lagerung dieser großen Wasserstoffmengen geht von den Druckgasflaschen selbst und insbesondere von den mit denselben verbundenen Versorgungsleitungen ein nur mit großem Aufwand einzuschränkendes Risiko einer Wasserstoffexplosion aus. Obwohl bei der bisher üblichen Versorgung, aufgrund der möglichst weit vom eigentlichen Einsatzort des Wasserstoffs entfernt liegenden Lagergestelle für die Druckgasflaschen, ein hoher leit- und maschinentechnischer Aufwand betrieben wird, besteht ein Restrisiko für die Bildung örtlicher zündfähiger Wasserstoff/Luftmischungen, die bei einer Explosion innerhalb eines Kernkraftwerkes zu Aktivitätsfreisetzungen führen kann.reactor plant with hydrogen In water-cooled nuclear reactor plants is used to condition the main coolant via the volume compensation system Hydrogen supplied. The hydrogen required for this has since become not insignificant Quantities stored in pressurized gas cylinders via pressure lines and a pressure reducing station are connected to the volume compensation system. When storing these large amounts of hydrogen goes from the pressurized gas cylinders themselves and in particular from those connected to them Supply lines represent a risk of a hydrogen explosion that can only be limited with great effort the end. Although with the previously usual supply, due to the as far as possible from actual place of use of the hydrogen distant storage racks for the Pressurized gas cylinders, a high level of control and machine technology is operated, there is a residual risk of the formation of locally ignitable hydrogen / air mixtures, the release of activity in the event of an explosion inside a nuclear power plant can lead.

Die Erfindung stellt sich daher die Aufgabe, eine Anordnung zur Wasserstoffversorgung einer wassergekühlten Kernreaktoranlage zu finden, die die Gefahr einer Wasserstoffexplosion sicher verhindert.The object of the invention is therefore to provide an arrangement for supplying hydrogen to find a water-cooled nuclear reactor facility that posed a risk of a hydrogen explosion safely prevented.

Gelöst wird diese Aufgabe erfindungsgemäß dadurch, daß ein Gerät zur elektrolytischen Erzeugung von Wasserstoff in der Nähe des Volumenausgleichssystems installiert und mit demselben über eine Versorgungsleitung verbunden ist.This object is achieved according to the invention in that a device for electrolytic generation of hydrogen near the volume equalization system installed and connected to the same via a supply line.

Durch die Verwendung dieses an sich bekannten Gerätes wird auf einfache und gefahrlose Weise die Versorgung mit Wasserstoff sichergestellt. Durch den unmittelbaren Anschluß des Gerätes an das Volumenausgleichssystem ist kein Vorratslager für Wasserstoff erforderlich. Er wird vielmehr nur in dem Umfang erzeugt wie er in der Kernreaktoranlage benötigt wird.The use of this known device is easy and safe way to ensure the supply of hydrogen. Through the immediate Connecting the device to the volume compensation system is not a storage facility for hydrogen necessary. Rather, it is only generated to the same extent as it is in the nuclear reactor facility is needed.

Ist das Gerät einmal auf den erforderlichen Abga-Dearuck von beispielsweise 10 bar eingestellt, ist weder eine zusätzliche Druckreduzierungs- noch eine Druckerhöhungsanlage erforderlich.Once the device has reached the required output dearuck of, for example 10 bar set, is neither an additional pressure reduction nor a pressure increase system necessary.

Durch die vorzugsweise Verwendung von Palladium als Elektrode wird ein sehr reiner Wasserstoff erzeugt.The use of palladium as an electrode is preferred a very pure hydrogen is produced.

Bevorzugt wird als Elektrolyt Lithiumhydroxid eingesetzt, um den EinfluB störender Fremdionen bei Verschleppung ins Primärkühlmittel zu verhindern.Lithium hydroxide is preferably used as the electrolyte in order to reduce the influence to prevent disruptive foreign ions from being carried over into the primary coolant.

Anhand einer schematischen Skizze wird die erfindungsgemäße Anordnung beschrieben.The arrangement according to the invention is illustrated using a schematic sketch described.

Innerhalb des strichpunktiert angedeuteten Sicherheitsbehälterslbefindet sich das Primärsystem 2 der Kernreaktoranlage. Mit 3 wird der Reaktordruckbehälter bezeinet, der über die Hauptkühlmittelleitungen 4, 5 mit den Dampferzeugern 6 verbunden ist. In den Leitungen 4 ist jeweils eine Umwälzpumpe 7 eingebaut. Über die F'rischdampfleitungen 8 gelangt der erzeugte Dampf zu der nichtdargestellten Turbine. Während des Betriebes der Kernreaktoranlage wird ein Teil des Hauptkühlmittels über die pumpensaugseitig angebrachte Leitung 9 des Volumenausgleichssystems zur Reinigung ausgespeist. Nach dem Passieren von Wärmetauschern 10 und Filtern 11 gelangt es über die Pumpe 12 wieder zum Hauptkühlmittelsystem.Located inside the safety container indicated by dash-dotted lines the primary system 2 of the nuclear reactor facility. 3 becomes the reactor pressure vessel bezeinet, which is connected to the steam generator 6 via the main coolant lines 4, 5 is. A circulation pump 7 is installed in each of the lines 4. Via the fresh steam pipes 8, the generated steam reaches the one not shown Turbine. During the operation of the nuclear reactor plant, part of the main coolant is over the line 9 of the volume compensation system attached to the pump suction side for cleaning fed out. After passing through heat exchangers 10 and filters 11, it arrives via the pump 12 back to the main coolant system.

Mit Hilfe des Volumenausgleichssystems, dessen Ausgleichsbehälter mit 13 bezeichnet ist, wird über die Versorgungsleitung 16 Wasserstoff in das Hauptkühlmittel eingespeist.With the help of the volume compensation system, its expansion tank is denoted by 13, is via the supply line 16 hydrogen in the main coolant fed in.

Erfindungsgemäß ist nun die Versorgungsleitung 16 unmittelbar mit einem Gerät 17 zur elektrolytischen.Wasserstofferzeugung verbunden. Das Gerät ist möglichst nahe an dem Volumenausgleichssystem angeordnet, so daß die Versorgungsleitung nur kurze Wege zu überbrücken hat. Durch das Auslegen des Gerätes auf einen Abgabedruck von 10 bar ist zwischen dem Gerät und dem Volumenausgleichssystem keine Druckregelstation erforderlich. Ebensowenig ist ein Vorratslager für Wasserstoff notwendig, da nur soviel Wasserstoff erzeugt wird, wie für die Konditionierung des Hauptkühlmittels benötigt wird. Als Sicherheitsmaßnahme ist lediglich das Gerät 17 auf Leckagen zu überwachen-. Bei austretendem Wasserstoff wird das Gerät automatisch abgeschaltet und das Ventil 18 in der Versorgungsleitung 16 geschlossen. Eine weitere Wasserstoffproduktion findet nicht statt, so daß die Gefahr einer Knallgasbildung nicht auftreten kann.According to the invention, the supply line 16 is now directly connected connected to a device 17 for the electrolytic generation of hydrogen. The device is Arranged as close as possible to the volume compensation system, so that the supply line only has to cover short distances. By designing the device for a delivery pressure of 10 bar, there is no pressure control station between the device and the volume compensation system necessary. Neither is a storage facility for hydrogen necessary, as only as much hydrogen is generated as for the conditioning of the main coolant is needed. As a safety measure, only the device 17 is closed for leaks monitor-. If hydrogen escapes, the device is switched off automatically and the valve 18 in the supply line 16 is closed. Another hydrogen production does not take place, so that the risk of oxyhydrogen formation cannot occur.

Die erfindungsgemäße Anordnung bringt mit einfachen Mitteln eine gefahrlose und wirtschaftliche Wasserstoffversorgung einer Kernreaktoranlage.The arrangement according to the invention is safe with simple means and economical hydrogen supply of a nuclear reactor plant.
