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.

The paper analyzes the results of reactor studies on tritium generation and release from the lead-lithium eutectic PbLi in conditions of reactor irradiation. In this paper, the initial stage of eutectic irradiation is considered. The dependences of tritium and helium release at a reactor power of 1 MW and the following eutectic temperatures were considered: 573, 673, and 773 K. Using an integrated model based on solving related systems of equations, including heat transfer equations, convective mass transfer equations, and diffusion equations, equilibrium temperature distributions over the eutectic were calculated. The evolution (time variation) of tritium concentration distributions in the volume of the eutectic and in traps at different temperatures of the eutectic is calculated.
