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.”

Light water reactors in the Federal Republic of Germany are being retrofitted with venting filters for use after serious reactor accidents. Deep-bed stainless steel fiber filters remove droplets and particles as well as high-efficiency particulate air filters. The deep-bed stainless steel fiber filters consist of two layers of fleece. The fiber diameter decreases gradually from 30 to 2 µm in the direction of flow. In addition to its high removal efficiency, its resistance to extreme loads, and its high dust loading capacity, the filter is important because it completely separates droplets. Even after 130 h of spraying with fine (2- to 5-µm-diam) droplets, a maximum increase in differential pressure of only 3 mbars was measured. No penetrating water was detected on the downstream side. Even at a flow of more than twice the recommended rate, the removal efficiency only dropped from ≥99.99 to ∼99.95%. An iodine filter can also be installed in each of the venting filters. Iodine experiments were conducted to determine the design of the iodine filter. The data obtained in experimental work using special silver zeolites are reported.
