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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

The method of overlapping neutron spectra has been developed by Selengut to calculate neutron spectra and reaction rates in weakly absorbing media with temperature discontinuities. A combination of Selengut's method with multicollision probability theory leads to a new thermalization method suitable to a wider field of application, especially to the homogenization of reactor cells. Based on this theory, the code THERMAL has been written. The results of THERMAL have been compared with those of the standard transport code THERMOS. Comparison of the results gave a satisfactory correspondence. Compared to THERMOS, the computing time and the storage capacity requirements of THERMAL are fairly small.
