Simulation of the THTR-300 referring to transients recorded during the test phase

Description

Following the construction of the THTR-300 measured values describing the behaviour of the whole power plant have been stored on magnetic tapes. Task is now to show that the power plant simulation program ALAMO is able to calculate the behaviour of the THTR-300. Calculations are done for stationary core, normal working power plant with varying power production, fast turbine shutoff and fast shutdown of the reactor. In addition, the helium-flow in the primary circle is explained. Especially the mass of the helium that bypasses the pebble bed is calculated. (orig.)

Abstract (German)

Nach der Fertigstellung des THTR-300 wurden Inbetriebnahmeversuche durchgefuehrt und die dabei gemessenen Kraftwerksdaten auf Magnetbaendern aufgezeichnet. Im Rahmen dieser Arbeit wird am Beispiel folgender Betriebsarten gezeigt, dass das Anlagenprogramm ALAMO geeignet ist, den THTR-300 zu simulieren: stationaerer Corezustand, Lastbetrieb bei veraenderlicher Kraftwerksleistung, Turbinenschnellschluss und Schnellabfahren. Zusaetzlich wird der Primaerkreis gesondert betrachtet, wobei die Heliumbypaesse, die nicht den Kugelhaufen durchstroemen, berechnet werden. (orig.)
