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.

High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

The excitement over nuclear technology has reached new heights. Not since the 60s have the prevailing winds been so strong at our backs.
A good set of policies driven by historic bipartisan support in Washington and increased interest at the state level. Long term electricity demand growth trends, propelled by AI/data centers and the re-shoring of domestic manufacturing, are real and increasingly appear durable.
Nuclear has finally reached the high ground. The hardest part of the journey, however, still lies ahead.
The industry faces a set of steep challenges as it moves from conceptual designs to detailed engineering, and from First of a Kind (FOAK) to Nth of a Kind (NOAK) costs, while navigating the NRC licensing process, new financing models, fuel availability and waste management issues, and the need for a rapidly growing nuclear workforce.
No challenge is insurmountable, but they will require the collective commitment of the entire U.S. nuclear enterprise—developers, suppliers, national labs, universities, investors, off-takers, high school science teachers—to succeed. Most of all, it will require the knowledge, experience, creativity and fortitude of every man and woman who in some way devote themselves to harnessing the power of the atom.
Kicking off barely two weeks after an historic election, this year’s ANS Winter Conference promises to be a unique opportunity to take stock of the hard technical challenges ahead and see the paths to success. Join us as we roll up our sleeves and get to the hard part.
