Description
Bypaßsteuerung für Kernreaktoranlagen Die Erfindung betrifft eine Bypaßsteuerung zur Verhinderung von unzulässig hohen Dampfdurchsatzschwankungen bei von Kernreaktoren, insbesondere Überhitzerreaktoren, gespeisten Dampfkraftanlagen durch Verbindung von Frischdampfleitung und Kondensator mittels zweier Bypaßleitungen, wobei die erste Bypaßleitung mit einem Schnellöffnungs-und einem Zusatzregelventil ausgerüstet ist, während die zweite Bypaßleitung von einem Regelventil geöffnet oder geschlossen werden kann.Bypass Control for Nuclear Reactor Plants The invention relates to a Bypass control to prevent impermissibly high fluctuations in steam throughput in the case of steam power plants fed by nuclear reactors, in particular superheater reactors by connecting the main steam line and condenser by means of two bypass lines, wherein the first bypass line with a quick opening and an additional control valve is equipped, while the second bypass line is opened by a control valve or can be closed.
Änderungen von Dampfdurchsatzmengen können bei Kernreaktoranlagen, insbesondere überhitzerreaktoren, den Reaktorkern gefährden. Solche Schwankungen des Dampfstromes werden durch das Schließen von Schnellschlußventilen oder auch durch schnelles Herunterregeln von Turbinen, die mit Kernreaktoranlagen zusammenarbeiten, hervorgerufen.Changes in steam flow rates can occur in nuclear reactor systems, especially superheater reactors, endanger the reactor core. Such fluctuations of the steam flow by closing quick-acting valves or by quickly turning down turbines that work together with nuclear reactor systems, evoked.
Zweck der Erfindung ist es, mit absoluter Sicherheit zu gewährleisten, daß der Dampfdurchsatz eine vorgegebene maximale Änderungsgeschwindigkeit nicht überschreitet.The purpose of the invention is to ensure, with absolute certainty, that the steam throughput does not have a predetermined maximum rate of change exceeds.
Die Erfindung besteht darin, daß beim Schließen des Schnellschlußventils das mit letzterem gekuppelte Schnellöffnungsventil der ersten Bypaßleitung gleichzeitig öffnet, daß unabhängig von diesem Vorgang das zwischen dem Schnellöffnungsventil und dem Kondensator angeordnete, mit dem Turbinenregelventil gekoppelte Zusatzregelventil jeweils in der dem lastabhängigen Dampfdurchsatz entsprechenden Stellung gehalten wird und daß sich bei vom Schnellschluß unabhängigen Schließbewegungen der Regelventile das in der zweiten Bypaßleitung angeordnete, ebenfalls mit dem Turbinenregelventil gekoppelte Regelventil um einen äquivalenten Betrag öffnet und nach jeder Öffnungsbewegung selbsttätig mit einer einstellbaren Geschwindigkeit wieder schließt.The invention consists in that when closing the quick-acting valve the quick opening valve of the first bypass line coupled with the latter at the same time opens that regardless of this process between the quick opening valve and an auxiliary control valve coupled to the turbine control valve and arranged on the condenser each held in the position corresponding to the load-dependent steam throughput is and that independent of the quick closing closing movements of the control valves the one arranged in the second bypass line, also with the turbine control valve The coupled control valve opens by an equivalent amount and after each opening movement closes again automatically at an adjustable speed.
Um durch rasche Öffnungsbewegungen des Turbinenregelventils keine unerlaubten krassen Steigerungen des Dampfdurchsatzes hervorzurufen, besteht die Möglichkeit, die Turbinenregelung mit einem Vordruckgrenzwertregler auszurüsten.To avoid rapid opening movements of the turbine control valve cause unauthorized sharp increases in the steam throughput, the Possibility to equip the turbine control with a pre-pressure limit value controller.
In der Zeichnung ist schematisch ein Ausführungsbeispiel gemäß der Erfindung wiedergegeben.In the drawing, an exemplary embodiment according to FIG Invention reproduced.
Die vom Reaktor kommende Frischdampfleitung 10 führt über das Schnellschlußventil3 und das Turbinenregelventil 1 zur Turbine 11. Über die Bypaßleitungen 12 und 13 ist die Frischdampfleitung 10 direkt mit dem Kondensator 14" verbunden. Über die Schnellschlußauslösung 5 ist das Schnellöffnungsventil4 direkt mit dem Schnellschlußventil3 gekoppelt. Unabhängig davon wird das Zusatzregelventil 6 über den Turbinendrehzahlregler 2 jeweils in der dem Turbinenregelventill äquivalenten und durch den Dampfdurchlaß bedingten Stellung gehalten. Beim Herunterregeln des Turbosatzes wird das in der Bypaßleitung 13 angeordnete Regelventil 7 ebenfalls direkt vom Drehzahlregler 2 gesteuert, und zwar so, daß beim Schließen des Turbinenregelventils 1 das Bypaßventil 7 um einen äquivalenten Betrag öffnet und anschließend durch einen Schließmechanismus 8 selbsttätig mit einer einstellbaren Geschwindigkeit wieder schließt, um Dauerverluste von Dampf zu vermeiden.The live steam line 10 coming from the reactor leads via the quick-action valve 3 and the turbine control valve 1 to the turbine 11. The live steam line 10 is connected directly to the condenser 14 ″ via the bypass lines 12 and 13. The quick-action valve 4 is coupled directly to the quick-action valve 3 via the quick-action release 5. Independent of which the additional control valve 6, respectively in the equivalent to the Turbinenregelventill via the turbine speed controller 2 and held by the vapor passage conditional position. when shutting rules of the turbo set, the disposed in the bypass conduit 13 control valve 7 is also controlled directly by the speed controller 2 in such a way that when closing of the turbine control valve 1, the bypass valve 7 opens by an equivalent amount and then automatically closes again by a closing mechanism 8 at an adjustable speed in order to avoid permanent loss of steam.
