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.

Douglas Point Nuclear Generating Station: Not the reactor you may be thinking of
The proposed location of Douglas Point in Maryland, on the banks of the Potomac River, compared to currently operating nuclear plants in Maryland and Virginia.
The Douglas Point Nuclear Generating Station that is the subject of this article is not the CANDU reactor that operated in Ontario from 1966 to 1984. This one was a proposed nuclear power plant in Charles County, Md., that was to provide power to the Washington D.C. area, about 30 miles north of the intended site.
In the early 1970s, the Potomac Electric Power Company (PEPCO) was looking for additional means of generation. At the time, the Washington D.C. metropolitan area was one of the fastest growing regions in the nation.
Site selection was tricky for PEPCO, as the company was contending with a confined load in a growing urban area. A new site as near as possible to the load center that could house at least 2,000 MWe of generating capacity and keep development costs down was needed. Three sites were ultimately reviewed: Douglas Point on the lower Potomac River, a second site toward the mouth of the Potomac River, and a third on the shore of Chesapeake Bay.

Magnetron sputter deposition is an enabling technology for laser target fabrication. Solutions are readily available for the deposition of most sub-micron-thick elemental films on planar substrates. However, major challenges still remain for the development of robust deposition processes in regimes of ultrathick (over μm) coatings and nonplanar substrates. These challenging deposition regimes are directly relevant to laser target applications, including both sphero-cylindrical hohlraums and spherical ablators for inertial confinement fusion (ICF) targets. Understanding underlying physical mechanisms for a specific material system is crucial for process development, given the overall complexity of the deposition process, its nonlinear dependence on deposition parameters, and a very large process space, often precluding conventional process optimization approaches. Here, we describe our approach to developing new deposition processes and give practical advice with examples of new results from our ongoing studies of glassy boron carbide ceramics for next-generation ICF ablators and nonequilibrium gold-tantalum alloys for hohlraums for magnetized ICF schemes. Emphasis is given to two major challenges of ultrathick coatings related to achieving process stability and reducing residual stress.
