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.”

Chemically reactive nitrogen tetroxide (N2O4 ⇌ 2NO2 ⇌ 2NO + O2) is discussed as a possible working fluid for power-producing thermodynamic cycles. Computation of the thermodynamic properties of the dissociating N2O4 system in liquid and gas phases is based on Soviet sources, since the most extensive research has been carried on at the Institute for Nuclear Energy in Byelorussia, where N2O4 is proposed as a coolant for fast-neutron gas reactors. Kinetics of the chemical reactions are considered by comparison between cycle parameters with equilibrium working fluid in all plant components and computations with frozen second reaction in the turbines. The results of the research, and the pros and cons of the system from the thermodynamic point of view, are discussed in the conclusion.
