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.

Judge temporarily blocks DOE’s move to slash university research funding
A group of universities led by the American Association of Universities (AAU) acted swiftly to oppose a policy action by the Department of Energy that would cut the funds it pays to universities for the indirect costs of research under DOE grants. The group filed suit Monday, April 14, challenging a what it termed a “flagrantly unlawful action” that could “devastate scientific research at America’s universities.”
By Wednesday, the U.S. District Court judge hearing the case issued a temporary restraining order effective nationwide, preventing the DOE from implementing the policy or terminating any existing grants.

Addition of sodium hydroxide to radioactive waste solutions produced a heterogeneous mixture of solids that exhibit different settling characteristics. Plutonium effectively coprecipitated with iron and uranium, and uranium with iron. Aluminum proved ineffective as a coprecipitating agent for either plutonium or uranium. Coprecipitation of uranium and plutonium occurs when the mole ratio of coprecipitating agent to actinide exceeds 1500. Addition of water to the alkaline slurries that simulate dilution during retrieval and pretreatment of high-level wastes results in dissolution of small amounts of uranium and plutonium in some slurries. The amount of uranium and plutonium dissolved did not saturate the solution in either actinide.
