Core Physics Analysis of An Assembly of HTTR Reactor using Homogeneous and heterogeneous model.
Moustafa Aziz
Abstract:MCNPX computer code based onMonte Carlo method is used to design a computer model for an assembly of high temperature testing reactor (HTTR). Two models are used in the analysis, namely homogeneous and heterogeneous models. The reactor uses TRISO fuel, Graphite moderator and helium coolant. The multiplication factor of the assembly is determined as a function of fuel burnup and operation time. Axial power mapping distributions are evaluated. Time evolution of actinides (U 235 and Pu 239 ) is calculated as a re… Show more
