ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

NRC v. Texas: Supreme Court weighs challenge to NRC authority in spent fuel storage case
The State of Texas has not one but two ongoing federal court challenges to the Nuclear Regulatory Commission that could, if successful, turn decades of NRC regulations, precedent, and case law on its head.

Fluorination of uranium and plutonium oxides to the volatile hexafluorides, UF6 and PuF6, is a major step for the fluidized-bed volatility processing of spent Zircaloy-clad UO2-PuO2 power reactor fuel. This step was studied in a 2-in.-diam reactor using 0.3- to 1.2-kg charges of simulated spent fuel pellets containing UO2, PuO2, and nonradioactive oxides of elements that would be formed in fission. Retention of uranium and plutonium by the fluidized bed of inert alumina, which is discarded after serving as a heat-transfer medium, was minimized and amounted to only 0.02% of the uranium and 3.5% of the plutonium in a 0.65-kg pellet charge. The total plutonium retention was reduced to ∼ 1% of the plutonium charge by using a single 1.2-kg bed of alumina to process three charges (1.95 kg) of fuel pellets.
