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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Between 1983 and 1989, the Fuel Behavior Studies Branch of the Commissariat à l’Energie Atomique-Grenoble performed eight tests in the HEVA (helium and vapor) program. This program, which is a part of the general French Institute for Nuclear Protection and Safety program concerning severe accident studies, is devoted to the measurement of fission product (FP) release rates under severe accident conditions. Each test was performed with a small section (three pellets) of a standard pressurized water reactor fuel rod in its original cladding, heated in a high frequency furnace, at temperatures up to 2300 K, in a steam and hydrogen environment. The volatile FP release rates were measured by gamma spectrometry. Posttest examinations supplied further information about the behavior of the FP, mainly concerning the aerosol sizing and the chemical speciation of the deposits. The results were compared with those obtained by other laboratories and with the calculated values. The measured release rates are generally lower than those calculated using the CORSOR model. A large influence of the environment is evidenced. The aerosol mean aerodynamic diameter is ∼0.3 µm. The HEVA program is extended by the VERCORS program mainly devoted to low volatile FP release rates and kinetics.
