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.

Virginia utility considers SMRs
Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

Experimental data acquired from cylindrical and annular pulsed columns equipped with either conventional sieves or baffle plates are well reproduced by the DYNAC computer model during steady-state and transient operation, even under off-normal conditions. This confirms that the model is useful in the design of pulsed columns with various geometries as well as in the estimation of extractor performance. The inherent differences between pulsed columns and mixer-settlers are also discussed for the plutonium separation process. Intrastage liquid mixing causes marked hydrodynamic tailing of solutes because of the difference in the mixing mechanisms and the residence time distributions of the fluids.
