Division Spotlight
Nuclear Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.
The American Nuclear Society (ANS) invites its members to apply for a one-year Washington, D.C.–based Congressional Fellowship. The ANS Congressional Fellow appointment helps the Society fulfill its strategic goal of enhancing nuclear public policy.
As an ANS Congressional Fellow, you will have the opportunity to work in either a U.S. Senator's or Representative's personal office or with a Senate or a House Committee, and become a direct contributor to the federal policymaking process. Along with providing Congress with expertise in nuclear science and technology, the Fellow will support other issues of importance. In return, the Fellow will gain a better understanding of how the legislative process works. Often the year as a "Beltway Insider" results in a new career direction.
As an ANS Congressional Fellow, you will be one of nearly 30 scientists and engineers participating annually through the American Association for the Advancement of Science (AAAS) Congressional Science and Engineering Fellowship Program. More than 2,000 have served as Fellows on Capitol Hill since the inception of the AAAS program in 1973. ANS initiated its program in 2000. The ANS Congressional Fellowship term runs from January through December each year. In 2023, ANS expanded its program and now hosts two Congressional Fellows.
ANS encourages interested members to apply. Experience the inner workings of Congress and contribute to improving understanding about nuclear issues among congressional leaders through this once in a lifetime opportunity.
"I am very grateful to the American Nuclear Society for this immense opportunity. It has been an amazing journey and a life changing experience to be advising Senator Feinstein on nuclear issues, as part of the energy, transportation, and climate change portfolios. The ANS Congressional Fellowship provides great opportunities for a nuclear professional to participate in federal policymaking and experience firsthand the intersections between federal and state policy, theoretical science, and engineered technology. The ability to understand the role policy plays in the nuclear industry is essential for future leaders."

The Fellowship program compensates the Fellow with an $95,000 annual stipend, payable in monthly installments over 12 months, plus up to $10,000 in travel reimbursement for expenses related to attending the AAAS orientation in September prior to the official start date, and the two ANS National Meetings in June and November of the Fellowship year. Any expenses above these are the responsibility of the Fellow. ANS also agrees to pay up to $5,000 towards out-of-pocket health insurance premiums not covered by AAAS or other programs during the year long Fellowship.
Must fulfill one of the following at minimum before Fellowship start date of January 1:
To apply for the ANS Congressional Fellowship you must submit the following information in a Word, PDF or other compatible format to fellow@ans.org before the stated deadline:
"It was a great and unique opportunity for me. The legislation I was working on (in the office of U.S. Senator Chuck Hagel (R-NE) - the Energy Policy Act of 2005 - was passed into law."
