Methods for Calculation of Thermal Multiplication Constant, Resonance Escape Probability and Fast Fission Factor for Low Enrichment Reactors

摘要

Previously, a homogeneous model has been used for calculation of these semesters. The method presently being used incorporate the effect of hetero-gemtty into the calculation of thermal multiplication constant and resonance escape probability. The fast fission factor is still calculated on the basis of a homogeneous model, but a new correlation has been chosen which gives a better fit to available experimental data.
