The Third Eurasian Conference Nuclear Science and Its Application : Proceedings, (s. 97-101). 5-8 October, 2004. Tashkent, Uzbekistan.http://kurumsalarsiv.tenmak.gov.tr/handle/20.500.12878/877Time dependence of temperature distribution in a TRIGA type fuel element following the pulse operation was calculated by using the computer code TEMPUL for different coolant velocities in the coolant channel. The effect of the air gap produced between the fuel bulk and the cladding interface by pulsing was considered in the temperature distribution calculations. The code was developed for the analysis of boiling crisis and DNB conditions in TRIGA core after the pulse operation and provided necessary database consisting of material properties for several types of TRIGA fuel. It solves the diffusion equation for heat transfer in cylindrical geometry using finite difference method. The form of flow channel is equilateral triangle, bound by three cylindrical fuel elements. The coolant in coolant channel has a constant velocity, which is an input data and that axial power distribution is a cosine function. The results from the calculation show that the fuel temperature will never be exceeded under any conditions of after the pulse operation.enginfo:eu-repo/semantics/openAccessTriga type fuel elementTriga tipi yakıt elemanıCalculation of the temperature distributionSıcaklık dağılımının hesaplanmasıThe pulse operationDarbe operasyonuconferenceObject97101
