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.

This paper presents a summary of scientific results obtained during the last few years in the National Research Centre "Kurchatov Institute" (NRC KI). The main aims of this research are the development of a new experimental method that can be applied for the investigation of the influence of a high level of radiation damage on the plasma erosion effects of irradiated materials (graphite materials and tungsten) at different temperatures and the investigation of hydrogen isotope accumulation in these materials relevant to fusion reactor conditions (in ITER).A high level of radiation damage in these materials (0.1 to 10 displacements per atom) was achieved by irradiating them with fast charged particles at the NRC KI cyclotron, simulating fast neutron irradiation in a fusion reactor. The plasma erosion effects in irradiated and nonirradiated materials were compared using the linear plasma simulator LENTA at NRC KI.The performed investigations have shown that the erosion factor of irradiated graphite materials is increased and the tungsten surface structure is changed due to the accumulation of radiation damage. No influence of irradiation on tungsten erosion rate was observed in these experimental tests. The accumulation of hydrogen isotopes and helium concentrations were measured in the irradiated tungsten.The performed work and the obtained results suggest a new promising experimental method for the experimental investigation of plasma effects on fusion structural materials at different irradiation temperatures and different radiation damage levels.
