EFFECT OF REFLECTOR MATERIAL ON NEUTRON CALCULATION OF MEU RESEARCH REACTOR
Keywords:
NONAbstract
Effect of different reflector material like graphite, beryllium on core excess reactivity and multigroup neutron fluxes have been studied using standard computer codes Wims –D4 & Daixy. Four energy groups, x-y calculation have reflected on two opposite faces by single row of the graphite / beryllium reflector. The core reflected by single row of graphite and beryllium has a percentage excess reactivity of (14.6) and (16.8) respectively.
