ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Type 316 stainless-steel specimens have been irradiated in the High Flux Isotope Reactor at temperatures between 380 and 680°C to displacement damage levels up to 120 displacements per atom and transmutation produced helium contents up to 6090 ppm. Swelling in solution annealed samples was found to be smaller than predicted by the helium swelling models but larger than predicted by fast reactor irradiation results, and the temperature dependence of swelling was also not in agreement with either prediction. Cold work reduced swelling for irradiation temperature up to 600°C but was ineffective at 680°C. For both annealed and cold-worked materials, the swelling was nearly temperature independent between 380 and 600°C but increased markedly at 680°C. Present models are inadequate to explain the swelling results in the presence of these high helium concentrations.
