Description

The reactivity effect of materials introduced into a critical reactor is generally a result of complex changes given to the system concerned. In this report, the emphasis was put on the space dependent reactivity effect of fuel, and its fission and absorption terms were separately measured. The effect of fuel enrichment on reactivity was also measured by using fuel elements of three different enrichments, 2.6%, 0.71% and 0.28%. The analysis was made by three group perturbation equations and its applicability was carefully checked in comparison with experimental results. (author)
