Sensitivity of the simulation of passive neutron emission from UF6 cylinders to the uncertainties in both 19F(α,n) energy spectrum and thick target yield of 234U in UF6

The calculation of light element impurity (α, n) yield curves in a PuO2 matrix and associated specific yield coefficients: Influence of the reaction cross sections

“…Note, the basic nuclear data used to generate these tables generally does not support more than three significant figures. The F(α,n) reaction is extremely important in the nuclear fuel cycle both as a contaminant and also because it accounts for a large part of the neutron source term in low-enriched U stored as bulk UF6 [17]. The shape and energy of the yield curve has been reviewed recently [18].…”

Commissioning of miniBELEN-10A, a moderated neutron counter with a flat efficiency for thick-target neutron yields measurements

“…Moreover, (α, n) reactions are important in underground physics, as they are one of the main sources of the neutron-induced background in underground facilities, which is typically a crucial issue for the experiments carried out there [3]. Other fields of interest include nuclear technologies such as fission [4] and fusion reactors [5] and non-destructive assays for non-proliferation and spent fuel management applications [6,7].…”

“…( , ) reactions are also one of the main sources of the neutron-induced background in underground laboratories, which is a crucial issue in the low counting rate experiments carried out there [3,4]. Other fields of interest include nuclear technologies such as fission and fusion reactors [5,6] and non-destructive assays for nonproliferation and spent fuel management applications [7,8].…”
