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.

Virginia utility considers SMRs
Dominion Energy Virginia has issued a request for proposals from leading nuclear companies to study the feasibility of putting a small modular reactor at its North Anna nuclear power plant.
While the utility says it is not a commitment to build an SMR at the site, the RFP is “an important first step in evaluating the technology and the North Anna site to support Dominion Energy customers’ future energy needs consistent with the company’s most recent Integrated Resource Plan.”

Atomic Energy of Canada Limited (AECL) has performed probabilistic safety assessments (PSAs) of Canada deuterium uranium (CANDU) reactor support systems since 1975. AECL’s experience in the use of PSAs on support systems and the application of the PSA for the CANDU 3 are described. The PSA work reviews support system failures such as loss of service water and loss of instrument air as initiating events during full power and during plant shutdown conditions. The design changes resulting from this work, with respect to prevention of loss-of-coolant accidents and maintaining a long-term heat sink, are described. The use of PSAs is being initiated early in the design of the next-generation CANDU reactor (CANDU 3) to avoid the possibility of design changes and backfits during the construction phase of the project.
