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.

NRC updating GEIS rule for new nuclear technology
The Nuclear Regulatory Agency is issuing a proposed generic environmental impact statement (GEIS) for use in reviewing applications for new nuclear reactors.
In an April 17 memo, NRC secretary Carrie Safford wrote that the commission approved NRC staff’s recommendation to publish in the Federal Register a proposed rule amending 10 CFR Part 51, “Environmental Protection Regulations for Domestic Licensing and Related Regulatory Functions.”

The Toroidal Field (TF) system of ITER consists of 18 coils in which the winding pack (WP) is formed by 7 stacked double pancakes (DP). The conductors in the TF coil are operated in steady state mode with a current of 68 kA providing a flux of 5.4 T at the plasma axis. The conductors are wrapped with turn insulation and embedded in grooves manufactured in so called radial plates. The grooves are closed with covers, wrapped with glass and polyimide tapes and vacuum impregnated. This layout of the TF WP prevents the accumulation of stresses in the turn insulation, making unlikely the occurrence of a turn-to-turn short circuit. The insulation of the WP will undergo during ITER design lifetime fast neutron fluencies up to 3.2x1021n/m2, which is equivalent to 10 MGy. Standard epoxies degrade if submitted to such doses, developing mechanical properties that would not withstand the estimated operation in-plane shear stress in the range of 45 MPa. The use of a radiation-hard thermoset for glass-fiber composites (cyanate ester) is considered and the on-going extensive qualification work will be presented. The technical solution of how to isolate critical High Voltage (HV) areas like the joint connections or voltage taps is also discussed.
