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.

Lloyd’s Register supports Prodigy’s bring-your-own-reactor floating plant concept
Prodigy Clean Energy and Lloyd’s Register have announced a collaboration to support the deployment of Prodigy’s “transportable nuclear power plants” (TNPPs) in Canada by 2030. Prodigy’s goal is to build marine-based nuclear power plants that are compatible with different end uses and reactor suppliers. What the plants would have in common is offshore siting close to an end user, which could include offshore oil and gas platforms, commercial seaports, mining operations, remote communities, and desalination plants.
