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.

New laws offer nuclear industry incentives for existing power plant uprates
This year, the U.S. nuclear industry received a much-needed economic boost that could help preserve operating nuclear power plants and incentivize upgrades that extend their lifespan and power output.
Signed into law in 2022, the Inflation Reduction Act offers production tax credits (PTCs) for existing nuclear power plants and either PTCs or investment tax credits (ITCs) for new carbon-free generation. These credits could make power uprates—increasing the maximum power level at which a commercial plant may operate—a much more appealing option for utilities.

A round die hot coextrusion technique used to prepare rods having complex cross sections has been developed and successfully applied to the fabrication of powder metallurgy parts with and without external cladding. The procedure involves assembling and extruding steel billets of round cross section which contain an axially located assembly of powder metallurgy and sheet metal parts which is an enlarged and shortened mockup of the desired part. After extrusion, the steel parts are removed and a fully dense rod having the desired shape and composition remains. Rods having several compositions in metal lurgically joined zones along their lengths can be produced by this method. For example, a Y-shaped rod with a Ti-25 volume per cent Eu2O3 dispersion at one end, a Ti-10.7 volume per cent B10 dispersion midsection, and a pure Ti length at the other end was successfully produced. It showed dimensional uniformity in keeping with usual tolerances for reactor control components and was clad with a fully bonded, 0.005-inch thick layer of titanium. Data on the physical properties, corrosion performance, thermal cycling resistance, and irradiation damage resistance of parts produced by this technique are presented. These data indicate that the method can be successfully used to produce reactor components which are very difficult to manufacture by other techniques.
