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.

Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

A new type of experimental apparatus is developed to induce continuous diffusion of deuterium, in which an electrochemical cell for calorimetry and a vacuum chamber for nuclear measurement are divided by a Pd sheet. Continuous X rays ranging from 10 to 100 keV and neutron and excess heat production are observed using the apparatus. Titanium atoms are detected on the surface where deuterium atoms pass through on Pd cathodes after electrolysis. Quantitative discussion shows that the detected Ti atoms cannot be explained by contamination. An electron-induced nuclear reaction (EINR) model for explaining the obtained experimental results is introduced. Experimental support of the EINR model is demonstrated by using multilayer cathodes, in which a layer containing Ca is placed at the near surface of Pd, based on the EINR model.
