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 effects of tritium on the corrosion behavior of chromium were investigated in the present study, since it was suggested in the previous studies that the elution of chromium, which is one of the main constituent elements of passive layer of SUS 304 stainless steel, during passivation through further oxidation induced by oxidative radiolysis products would be the key reaction for the enhancement of the corrosion of SUS304 stainless steel induced by tritium. As the experimental results of the dependence of both dissolved oxygen and tritium concentration on the anodic behavior of chromium, it was found that the self-passivation of chromium induced by dissolved oxygen was inhibited in the tritiated solution, as found in the previous studies for SUS304 stainless steel. Therefore, it was considered that the elution of chromium by highly oxidative radiolysis products would induce a passivation inhibitory effect onto SUS304 stainless steel in a tritiated solution, resulting in an enhancement of the corrosion.
