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.

A field-reversed configuration (FRC) plasma is a high-beta elongated compact toroid only with a poloidal field. Since the plasma torus does not link with confinement coil and vacuum vessel, the FRC can be translated from the formation region to confinement region along the external guide field. In this work, the effects of particle, flux and energy supply to the FRC due to the interaction with background neutral particles has been investigated. Translating an FRC plasma through a neutral gas background is equivalent to the injection of neutral beam end-on into the FRC. The experiments were performed on NUCTE-III and NUCTE-III/T. Due to the effects of back ground particle injection during translation process, the loss rate of particle, flux and energy were reduced.
