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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.
