Standard Test Method for Determination of Effective Boron-10 Areal Density in Aluminum Neutron Absorbers using Neutron Attenuation Measurements

Importancia y uso:

5.1 The typical use of this test method is determination of ¹⁰B areal density in aluminum neutron absorber materials used to control criticality in systems such as: spent nuclear fuel dry storage canisters, transfer/transport nuclear fuel containers, spent nuclear fuel pools, and fresh nuclear fuel transport containers.

5.2 Areal density measurements are also used in the investigation of the uniformity in ¹⁰B spatial distribution.

5.3 The expected users of this standard include designers, suppliers, neutron absorber users, testing labs, and consultants in the field of nuclear criticality analysis.

5.4 Another known method used to determine areal density of ¹⁰B in aluminum neutron absorbers is an analytical chemical method as mentioned in Practice C1671. However, the analytical chemical method does not measure the “effective” ¹⁰B areal density as measured by neutron attenuation.
