Monte Carlo uncertainty analyses for integral beryllium experiments

摘要

The novel Monte Carlo technique for calculating point detector sensitivities has been applied to two representative beryllium transmission experiments with the objective to investigate the sensitivity of important responses such as the neutron multiplication and to assess the related uncertainties due to the underlying cross-section data uncertainties. As an important result, it has been revealed that the neutron multiplication power of beryllium can be predicted with Good accuracy using state-of-the-art nuclear data evaluations.
