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.”

The techniques of photolithography and vacuum coating have been investigated, primarily as a means of producing three-dimensional structures. Using ultra-smooth glass capillary tubes as a substrate, and a rotational drive system, multiple free-standing cylinders can be fabricated on the surface. These are produced by a combination of metallisation and photolithography to accurately define the desired structure with precise edge definition. Owing to the rotary motion of the photolithography technique, it was found that by changing the physical shape of the mask directly varied the exposure time at different points, forming structures with definable surface topographies (e.g. cylinders with blazed or stepped cross-sections along their length). The advantages and limitations of these techniques are presented, highlighting the fabrication processes currently being developed to realise novel structures.
