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.

Military action destroys radiation monitor at Ukraine plant
An external radiation monitoring station was taken out by shelling and fire near the Zaporizhzhia nuclear plant in Ukraine the last week of June.
This brings the total to four of the plant’s 14 radiation monitoring sites that are out of commission, further reducing the effectiveness of its off-site capability to detect and measure any radioactive release during an emergency, said IAEA director general Rafael Mariano Grossi.

This paper discusses the results of investigations devoted to the study of steam condensation in the presence of air and a light noncondensable gas. A double strategy has been adopted, including complementary experimental and computational activities. Novel data have been made available by the CONAN (CONdensation with Aerosols and Noncondensable gases) facility, investigating the effects induced by light noncondensable gases in experimental configurations that were scarcely investigated in past studies. Computational fluid dynamics condensation models have been developed and validated. The suitability of helium as a substitute for hydrogen in experimental activities has been investigated by theoretical and computational analyses that allow establishing simple criteria for the scaling of condensation tests in the presence of a light noncondensable gas.
