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 system of neutron-lean tandem mirror satellite reactors using the deuterium-3He (D-3He) fuel cycle has been assessed. The 3He fuel is produced via a breeder reactor, also based on the tandem mirror reactor (TMR) concept. The TMR concept was selected because, for the satellite reactors, the fusion energy is mostly in charged-particle form, so efficient, direct energy conversion can be used. For the breeder, the TMR gives a higher maximum achievable support ratio than other concepts give. The optimum satellite operating temperature was found to be ∼75 keV. The safety and cost of the satellite/breeder system were assessed. The D-3He fuel cycle becomes particularly attractive if the deuterium-deuterium (D-D) reaction can be suppressed by nuclear spin polarization. For perfect D-D reaction suppression, this would allow immediate hands-on maintainability of reactor components and allow for reduction in the magnet dimensions, since the shield would no longer be required. For no D-D reaction suppression, ∼3% of the fusion power will be in neutrons. This will then require the use of ∼40-cm shielding, along with activation concerns. Hands-on maintenance f or the satellite reactor is possible even without D-D reaction suppression, if low-activation materials are used. The radioactivity level of the 3He breeder is comparable to that of a deuterium-tritium reactor. The cost of electricity for the system, including the fuel costs, is estimated f or this system.
