Feasibility Study of Measuring the ~(238)U Fission Rates by Neutrons of 14 MeV in Specifical Experiment Condition)

Abstract

Using uranium fission chambers of minitype slab in the case of 14 MeV neutrons penetrating through the special experiment model, the pure 238U absolute fission rates are measured. Comparing the measurement resluts with and without reflect shell, the reflect coefficient of shell is gained. The calculate results are compared with experiment results, to prove the model calculate method and parmeter.
