Description
Es ist bereits bekannt, zum Regeln der Aktivität eines Kernreaktors Metallstäbe zu verwenden, die die Neutronen absorbieren, wie z. B. sogenannte »Kontrollstäbe« aus Cadmium, die im Reaktor vertikal zwischen den Brennstoffstäben nach unten ragen. Diese Regelung ist jedoch nur bei einer ortsfesten Anlage anwendbar und stößt bei Schiffsanlagen auf Schwierigkeiten, die durch den Einfluß der Schwerkraft bei der Abwärtsbewegung gegeben sind. Auch wird durch diese Art der Regelung das Volumen des eigentlichen Reaktors durch die Vorrichtung beträchtlich vergrößert, die oberhalb des Reaktors zum Aufhängen und zur Bedienung der Kontrollstäbe erforderlich ist.It is already known to use metal rods to regulate the activity of a nuclear reactor, which the Absorb neutrons, such as B. So-called "control rods" made of cadmium, which are vertical in the reactor protrude down between the fuel rods. However, this regulation is only applicable to a stationary system applicable and encounters with ship systems difficulties caused by the influence of gravity are given during the downward movement. This type of regulation also reduces the volume of the The actual reactor is considerably enlarged by the device that can be hung above the reactor and is required to operate the control rods.
Man hat ferner zur Steuerung von Kernreaktoren auch schon dem zwischen den Brennstoffstäben strömenden Medien zur Beeinflussung der Reaktivität neutronenabsorbierende Substanzen beigegeben. Nach der Erfindung sollen nun diese Substanzen aus neutronenabsorbierenden Metallpartikeln bestehen, die in veränderbarer Menge an einer oder mehreren Stellen in die Umlaufbahn des zwischen den Brennstoffstäben strömenden Mediums eingeführt werden. Hierzu ist festzustellen, daß es bereits bekannt war, daß man einen Atomkernreaktor abschalten kann, indem man in ein System von Röhren, die zwischen den Brennstoffelementen angeordnet sind, ein Medium einströmen läßt, in dem neutronenabsorbierende Metallpartikeln suspendiert sind. Eine freie Regelung des Reaktors war indessen dabei nicht möglich.One also has to control nuclear reactors already that flowing between the fuel rods Media added to influence the reactivity of neutron-absorbing substances. After Invention, these substances should now consist of neutron-absorbing metal particles, which can be changed in Amount in one or more places in the orbit of the between the fuel rods flowing medium are introduced. It should be noted that it was already known that one An atomic nuclear reactor can be shut down by going into a system of tubes that run between the fuel elements are arranged, allows a medium to flow in, in which neutron-absorbing metal particles are suspended. Free regulation of the reactor was not possible.
Die neutronenabsorbierenden Metallpartikeln (z. B. Cadmiumkörner) können mehr oder weniger schwammig sein, damit sie entweder in dem Medium leichter in Suspension zu halten sind oder aber, damit sie, wenn sie nicht oder weniger schwammig sind, eine größere Dichte bzw. ein größeres spezifisches Gewicht erhalten und sich dadurch am Boden des Reaktors sammeln, wo sie dann wieder aufgenommen und von wo sie wieder in dem Medium verteilt werden.The neutron-absorbing metal particles (e.g. cadmium grains) can be more or less spongy so that they are either easier to keep in suspension in the medium or so that they, if they are not spongy or less spongy, a greater density or a greater specific weight received and thereby collect at the bottom of the reactor, where they are then taken up again and from where they are redistributed in the medium.
Die Metallpartikeln können an einer oder mehreren Stellen der Umlaufbahn, die von dem zwischen den Stäben hindurchgehenden Medium durchlaufen wird, in einer mehr oder weniger großen Menge zugesetzt werden, die von den für die Regelung der Aktivität des Reaktors gegebenen Erfordernissen abhängt. Ebenso können die Metallpartikeln an einer oder mehreren Stellen der Umlaufbahn wieder entnommen und wiedergewonnen werden, z. B. mit Hilfe von zur Abscheidung von Metallkörnern aus strömenden Medien an sich bekannten Mitteln.The metal particles can be at one or more points of the orbit that is between the Medium passing through rods is added in a more or less large amount depending on the requirements for regulating the activity of the reactor. Likewise, the metal particles can be removed again at one or more points in the orbit be recovered, e.g. B. with the help of for the separation of metal grains from flowing media known means.
Es ist ersichtlich, daß dieses Regelverfahren gemeinsam mit den an sich bekannten Vorrichtungen Verfahren zur Steuerung eines Kernreaktors It can be seen that this control method, together with the devices known per se, methods for controlling a nuclear reactor
