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.

Three analyses are presented for the Kuosheng plant, the second nuclear power station of the Taiwan Power Company. The first is a startup test benchmark analysis of full closure of the main steam isolation valves (MSIVs). This analysis is one of a series of startup test analyses to develop the Kuosheng RETRAN model. The second is a parallel reload safety analysis of a system pressure-limiting transient for Kuosheng Unit 2, Cycle 12, which is a part of work to develop an in-house reload safety analysis methodology. The third is an operating support analysis of a reactor trip event due to a single MSIV closure in October 1997; this analysis demonstrates the application of the Kuosheng RETRAN model. The work may add to the RETRAN experience base and to the plant modeling body of knowledge. A similar approach can be adopted to support the plant, with concerns.
