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.

Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

The design of a tritium processing loop for KATRIN tritium source and results of test set-up operation are presented. The constant source intensity is supported by high purity (> 95% of tritium) of tritium circulated through the source with 4.110-4 g/s rate. The possibility of source parameters stabilization was verified with test facility "TILO" which was built for this purpose. The long term (30 days) deuterium circulation with flow rate 0.2 Pa m3/s shows that using of standard high accuracy pressure sensors from MKS and NI control electronics allows to stabilize the flow rate in the system with 0.1% accuracy. The reliability of process equipment was tested as well during about 3000 h of TILO operation.
