[3G10-13] Subcriticality Experiment and Evaluation 1

[3G10] Student experiments using subcritical core with natural uranium

Keywords:Subcritical core, Student experiment, Exponential experiment

Kyoto University Critical Assembly could not be operated for more than 3 years because of investigation by Nulcear Regulation Authority for adapting to new regulatory requirements for research reactor. During this period, student experiments have been carried out using subcritical cores with natural uranium, for example, the exponential experiment and measurement of reaction rate distribution by changing subcriticality. The results of experiments and lessons learned from these experiments will be presented.
