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.”

Use of vanadium alloys is contemplated for the ITER blanket and guidance is needed to determine the extent of the data base for qualifying these alloys as structural material. A probabilistic methodology first employed in the fast breeder program is used to provide a preliminary assessment of the data base requirements. This methodology, which is applicable to any structural material, or in general to any design variable, determines the adequacy of the design by considering simultaneously all design affecting uncertainties, such as operational, nuclear, thermal-hydraulic, structural, geometric tolerances and material properties. In this study a thermal-mechanical calculational model of the ITER self cooled lithium blanket design was developed and the effect of design uncertainties on temperature (creep limited) and stress-strain (fatigue limited) were calculated. Based upon the current design, it was concluded that an uncertainty band of ± 30% on vanadium material properties is acceptable. Confirmatory irradiation data are however necessary.
