Abstract

Experimental and analytical studies have been performed to determine the temperature distribution as a function of reactor power in the TRIGA Mark-II reactor at the Istanbul Technical University (ITU). The lumped parameter model with four governing equations was used in the analytical model. Based on the mathematical model, a computer code has been developed for calculating fuel and coolant temperatures in the reactor core. The calculated results for fuel and coolant temperature in the reactor core for different reactor power levels have been compared with the experimental data. Agreements between experiment and results from the computer code are fairly good.

Abstract

Um die Temperaturverteilung als eine Funktion der Reaktorleistung zu ermitteln, wurden am TRIGA Mark-II Reaktor der Technischen Universität Istanbul (ITU) experimentelle und analytische Studien durchgeführt. In dem analytischen Modell wurde das Blockparametermodell mit vier Hauptgleichungen benutzt. Auf dem mathematischen Modell basierend wurde ein Computercode entwickelt, um die durchschnittliche Temperatur des Brennstoffs und des Kühlmittels im Reaktorkern zu berechnen. Die Ergebnisse der Berechnungen von durchschnittlicher Brennstoff- und Kühlmitteltemperatur im Reaktorkern bei unterschiedlicher Reaktorleistung wurden mit den experimentell ermittelten Daten verglichen. Die Übereinstimmung zwischen den experimentellen Daten und den berechneten Ergebnissen sind ziemlich gut.
