Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

An experiment to measure the multiplication of 14-MeV neutrons in bulk beryllium has been completed. The experiment consisted of determining the ratio of 56Mn activities induced in a large manganese bath by a central 14-MeV neutron source, with and without a beryllium sample surrounding the source. The superior isotropy and flat energy response of the manganese bath gives this detector an advantage over the inhomogeneous and anisotropic detector arrays used in previous experiments for measurements of this type. Values of the multiplication have been obtained for beryllium samples of four thicknesses. The measurements are affected by several systematic effects characteristic of the manganese bath. The values of these systematic corrections are established by a combination of calculation and experimental parameterization. Detailed calculations of the multiplication and all the systematic effects are made by using a highly detailed three-dimensional Monte Carlo geometry model with the MCNP Monte Carlo program. The Young-Stewart and the ENDF/BVI evaluations for beryllium are used in the analysis. Both data sets produce multiplication values that are in excellent agreement with the manganese bath measurements for both raw and corrected values of the multiplication. It is concluded that there is no real discrepancy between experimental and calculated values for the multiplication of neutrons in bulk beryllium.
