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.

From the pages of Nuclear News: Industry update September 2024
Here is a recap of industry happenings from the recent past:
BWXT advanced nuclear reactor agreement signed
Burns & McDonnell, a family of construction and design companies, has entered into an agreement with BWX Technologies to further advance the design and development of the BWXT BANR microreactor, which has a “passively safe design” for powering remote facilities while providing a carbon-free source of heat and electricity. The two companies completed the first phase of their collaboration in early 2024 and intend to complete the second phase by the third quarter of 2025. Burns & McDonnell is helping BWXT develop the balance-of-plant systems for the BANR, generate the power plant layout, and perform preconstruction planning. Its scope of work also includes developing power cycle architecture, identifying critical components, integrating site design, and supporting steam and power distribution infrastructure and reactor building structures. The Wyoming Energy Authority is currently evaluating the feasibility of using the BANR in a state nuclear market for baseload heat and power deployed for remote industrial users, such as mining operations.

The 1983 report of the Waste Isolation Systems Panel of the National Academy of Sciences (referred to as NAS-83) introduces a solubility limited dissolution (SLD) theory to estimate release rates from highlevel radioactive waste packages. It is pointed out that this theory, as presented, should apply equally well to each grain of average rock, but that when applied to that problem, it overpredicts the observed dissolution rate of SiO2 by seven orders of magnitude. The SLD theory also predicts that cesium and other trace elements are leached out of rock grains orders of magnitude more rapidly than the SiO2; it is shown that this is clearly contrary to the experimentally observed situation. Other shortcomings of the NAS-83 treatment are pointed out. Modifications to the theory that avoid these large discrepancies are suggested; when applied to the waste problem, they pose some very important questions that should be answered before proceeding with waste management problems. For example, they suggest that reprocessing may reduce the hazards from waste by a factor of 10 million, and that synroc may be millions of times more secure against leaching than waste glass.
