Description
Vorrichtung zur Verbesserung der Wirtschaftlichkeit von Leistungsreaktoren In Reaktoren kann aus materialtechnischen Gründen ein bestimmter Grenzwert der Temperatur nicht überschritten werden. Er liegt z. B. bei dem sowjetrussischen Druckwasser-Reaktor zwischen 260 und 275° C, beim Siedewassere-Reaktor und beim Natrium-Graphit-Reaktor etwas höher, aber nicht über 350° C. Derart niedrigen Temperaturen entsprechen - sofern man mit dem Reaktor Treibdampf für eine Wärmekraftmaschine erzeugen will - geringe Werte des thermodynamischen Wirkungs grades der gesamten Anlage, die zwischen 17 und 25°/o liegen. Da die verfügbaren Baumaterialien indes keine höhere thermische Belastung zulassen, ist man dazu übergegangen, den Gesamtwirkungsgrad der Anlage dadurch zu verbessern, daß man dem Reaktor einen mit fossilen Brennstoffen geheizten Überhitzer nachschaltet. Dieser Überhitzer bringt den Arbeitsdampf auf z. B. etwa 500° C, wodurch Wirkungsgrade bis zu etwa 35 0/0 erreicht werden können. Allerdings wird hierbei 10°/o der nutzbaren Gesamtleistung durch die fossilen Brennstoffe, also durch Fremdenergie, aufgebracht. Aus wirtschaftlichen und technischen Gründen ist es nun wünschenswert, daß diese Anteile an Fremdenergie möglichst gering gehalten werden. Dies wird durch die vorliegende Erfindung erreicht.Device for improving the profitability of power reactors For reasons of material technology, a certain limit value for the temperature can be set in reactors not be exceeded. He is z. B. in the Soviet Russian pressurized water reactor between 260 and 275 ° C, in the case of the boiling water reactor and the sodium-graphite reactor slightly higher, but not above 350 ° C. Such low temperatures correspond to - if you want to use the reactor to generate motive steam for a heat engine - low values of the thermodynamic efficiency of the entire system between 17 and 25 per cent. Since the building materials available, however, no higher thermal Allowing load, one has gone over to the overall efficiency of the system by adding a fossil fuel-fired reactor to the reactor Downstream superheater. This superheater brings the working steam to z. B. about 500 ° C, whereby efficiencies of up to about 35 0/0 can be achieved. However 10% of the total usable power is due to fossil fuels, so upset by external energy. For economic and technical reasons it is now desirable that these proportions of external energy be kept as low as possible will. This is achieved by the present invention.
Wie bekannt, entsteht im Reaktor eine hochenergetische Strahlung, die bis zu 5 % der bei der Kernspaltung frei werdenden Energie enthält und die im allgemeinen durch besondere Reflektoren und Schutzvorrichtungen abgeschirmt und so nutzlos vernichtet wird. Diese Strahlungsleistung steht also noch als nutzbare Reserve zur Erhöhung der Wirtschaftlichkeit zur Verfügung.As is known, high-energy radiation is generated in the reactor, which contains up to 5% of the energy released during nuclear fission and which in the generally shielded by special reflectors and protective devices and so uselessly destroyed. This radiation power is therefore still usable Reserve available to increase profitability.
Gemäß der vorliegenden Erfindung wird nun der Überhitz,er innerhalb der biologischen Abschirmung mantelartig um den Reaktor herum so angeordnet, daß dadurch zugleich eine Abschirmung und Nutzbarmachung der Reakto,rverluststrahlung bewirkt wird. Eine solche Anordnung des Überhitzers bewirkt, daß seine Wandungen und der in ihm zirkulierende Dampf Strahlungsenergie absorbieren und in Wärme umwandeln, die eine erhebliche Verminderung des Zusatzbedarfes an fossilen Heizstoffen ermöglicht. Gleichzeitig liefert der überhitzer in diesere Anordnung eine wirksameAbschirmung. Er vereinigt in sich somit die drei Funktionen der Überhitzung durch Fremdenergie, der Abschirmung und der Absorption und Nutzbarmachung sonst verlorengehender Strahlungsenergie unter Einsparung eines Anteiles an Fremdernergie.According to the present invention, the superheat now becomes within the biological shield arranged like a jacket around the reactor so that thereby at the same time a shielding and utilization of the reactor loss radiation is effected. Such an arrangement of the superheater causes its walls and the steam circulating in it absorb radiation energy and convert it into heat, which enables a considerable reduction in the additional demand for fossil fuels. At the same time the superheater in this arrangement provides an effective shield. It thus combines the three functions of overheating through external energy, the shielding and the absorption and utilization of otherwise lost radiation energy while saving a portion of external energy.
