ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

We have constructed a 2-dimensional Hα line-emission measurement system in order to study neutral hydrogen behavior. We can obtain 2-dimensional radial profiles of hydrogen density by considering a collisional-radiative model. We have also constructed space- and time-resolving spectrograph system in the range of vacuum ultraviolet (VUV). 15–105 nm. studying ion density profiles which directly relates to impurity transport. We measure both Hα line-emissions and VUV spectra from the hot ion mode plasmas in the GAMMA 10 for studying plasma particle confinement and impurity behavior. We found that both particle and energy confinement of the GAMMA 10 plasma was slightly improved during electron cyclotron resonant heating (ECRH) over that without ECRH. From the VUV measurement it is concluded that the impurity ions mainly came into the plasma during its formation phase.
