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.

An experimental study of neutron self-shielding in cobalt foils and wires has been made by an activation technique. Cobalt foils ranging in thickness from 0.0004 to 0.004 in. and 0.005 in. thick Co-Al alloy reference foils containing 1% Co were irradiated under cadmium in the NRX reactor. The Co60 specific activity in the pure foils was compared with that in the reference foils to give the gross self-shielding factors. Experimental resonance self-shielding factors were obtained by separating the 1/v part from the gross self-shielding factors, and agreement with calculated resonance self-shielding factors for foils was observed. Self-shielding factors for wire ranging in diameter from 0.001 to 0.025 in. and for 0.050 in. diam 1 % Co-Al alloy wire were also measured since they are of practical importance and have not been calculated. Measurements of self-shielding factors for thermal neutrons were made for cobalt wires and these agree with theory.
