This paper addresses the hot channel factors for the thermalhydraulic analysis of Material Testing Reactors (MTR). The criteria for choosing the hot channel factors and their combination methods are presented and discussed. A method for the evaluation of the hot channel factors for the thermalhydraulic analysis is proposed. In the proposed method, the values of the hot channel factor are calculated in terms of their fraction of variation and the degree of dependency of the thermalhydraulic safety parameter of interest on these factors. The equations for the calculation of the thermalhydraulic safety parameters in the hot channel are presented along with discussions. The application of the proposed method has been illustrated by an example.
