A study of a H2O-moderated 241AmBe source for neutron metrology

Brazilian Journal of Radiation Sciences
The update to ISO 8529-1 (2021) reduces the variety of neutron fields from sources. For neutron metrology, it is crucial to have a standard radiation field with known fluence and energy well-defined.

Comparison of two methods for assessment of the rod positioning uncertainty and consequences on the evaluation of correlation factors

Frontiers in Energy Research, 2022
In this paper two major families of methods to deal with the assessment of the rod positioning uncertainty in a lattice are tested: a traditional one described in the International Handbook of Evaluated Criticality Safety Benchmark Experiments (IHECSBE ...
