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.

Lithium metatitanate (Li2TiO3) is one of the candidate tritium-breeder materials for the ITER test blanket module (TBM) and the DEMO blanket. It will be used as the tritium-breeder material for the Indian lead-lithium–cooled ceramic breeder concept of the TBM to be tested in ITER. Thermal conductivity is one of the most important parameters in the design of TBMs using ceramic materials. The design of breeder blankets is strongly affected by the low values of the thermal conductivity and density of ceramic breeder pebble beds. A significant increase in both quantities would enhance thermal performance and lead to an increased tritium-breeding ratio. Thermal transport properties of Li2TiO3 were measured using the laser flash method, which determines the thermal diffusivity from the transient temperature rise measured at one side of a pellet with laser pulse heating at the other side. The thermal conductivity of Li2TiO3 pellets was then estimated from the experimentally obtained thermal diffusivity values. Finite element analysis using ANSYS software was performed to simulate the transient thermal measurements, and the results were compared with those obtained by the laser flash method. The experimental and simulation results were found to be in good agreement. The experimental details and ANSYS simulation are presented in this paper.
