ASTM WK27319

    Work Item: ASTM WK27319 - New Test Method for Determination of effective boron-10 areal density in aluminum neutron absorbers using neutron attenuation measurements

    (What is a Work Item?)

    Developed by Subcommittee: E07.05 | Committee E07 | Contact Staff Manager



    1. Scope

    This test method is intended for quantitative determination of effective boron-10 (10B) areal density (mass per area of 10B, usually measured in grams-10B/cm2) in aluminum neutron absorbers. The attenuation of a thermal neutron beam transmitted through an aluminum neutron absorber is compared to attenuation values for calibration standards allowing determination of the effective 10B areal density.

    The typical use of this test method is determination of boron-10 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. The expected users of this standard include designers, suppliers, and consultants in the field of nuclear criticality analysis.
