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.

WIPP improves utility shaft safety, begins infrastructure project
Harrison Western Shaft Sinkers (HWSS), the company drilling a new utility shaft at the Department of Energy’s Waste Isolation Pilot Plant in New Mexico, has retained a safety culture expert following a near-miss accident in the shaft late last year. The safety expert will conduct monthly facilitated discussions with crews working on the shaft to reinforce expectations for identifying concerns regarding unsafe circumstances, according to a recent report by the Defense Nuclear Facilities Safety Board (DNFSB).

The paper discusses the most accurate methods for description of turbulent flows: computationally very expensive Direct Numerical Simulation (DNS) and, slightly less accurate and slightly less expensive, Large Eddy Simulation (LES) method. Both methods have found the way into the nuclear thermal hydraulics as tools for studies of the fundamental mechanisms of turbulence and turbulent heat transfer. In the first Section of the paper, both methods are briefly introduced in parallel with the basic properties of the turbulent flows. The focus is on DNS method, the so-called quasi-DNS approach, and the coarsest turbulence modelling approach discussed in this work, which is still on the very small scale, wall-resolved LES. Other, coarser turbulence modeling approaches (such as wall-modelled LES, RANS/LES hybrids, or RANS) are beyond the scope of the present paper. Section 2. answers the question: "How do DNS and LES methods work?", with a short discussion of the computational requirements, numerical approaches and computational tools. Section 3. is about the interpretation of the DNS and LES results and statistical uncertainties. Sections 4. and 5. give some examples of the DNS and wall-resolved LES results relevant for nuclear thermal hydraulics. The last section lists the conclusions and some of the challenges, which might be tackled with the most accurate techniques like DNS and LES.
