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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

A feasibility study is presented of fast tokamak plasma terminations by means of high-Z impurity liquid jet injections in order to reduce the technological requirements of such terminations. The calculation was carried out by combining models described for the jet ablation and the current termination and taking into account the ionization of the jet material exposed to generated runaway electrons. The liquid jet was assumed to fragment and thus to deposit more massive impurity ions in the plasma. Although argon or krypton jet injection generates the runaway electron current, it decays in several hundred milliseconds with ionization of the residual jet material. These high-Z impurity jet injections would also be applicable for terminating or reducing the runaway electron current tails generated by major plasma disruptions.
