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.

Federal court finds in favor of Diablo Canyon license review
A review from the Ninth Circuit Court of Appeals this week denied a challenge to the Diablo Canyon nuclear plant’s license renewal application extension granted by the federal government.
In late 2023, the Nuclear Regulatory Commission agreed to formally docket the California plant’s request to extend plant operations beyond the current license expiration dates of 2024 and 2025 for the two respective units.

Production of 18F, a positron emitter, with fast protons from D-3He fusion reactions and oxygen (18O) impurities in a large tokamak is studied numerically. A high-energy deuterium beam is used for proton production enhancement. The yield of 18F is found to be optimized in a somewhat dirty plasma with an effective ionic charge number of Zeff ∼ 5 and doubled by the inclusion of the possible resonance in the 18O(p,n)18F reaction. The yield in the deuterium beam-injected 3He plasma is 1000 times larger than by standard methods using a cyclotron. A comparison is also made with the yield in an advanced plasma regime.
