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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

The BUCKY 1-D simulation code was used to simulate the hydrodynamic compression and thermonuclear ignition of a DT filled capsule that mimics the specifications set forth by the Fusion Test Facility (FTF) working group. This paper focuses on two key aspects of the ongoing hydrodynamics simulation work being performed at the University of Wisconsin.The first set of simulations was performed to obtain a baseline result for comparison. This baseline utilized the High Average Power Laser (HAPL) target ion and X-ray threat spectra scaled down from 365 MJ to 29.75 MJ. The second set of simulations was a target simulation initiated from conditions that were expected to be found at the point of ignition of the FTF DT target.The results of these simulations allowed for the creation of time-dependent X-ray and ion threat spectra, which will be used in future chamber simulations in support of the FTF design effort to assess the thermal response of test modules located within the facility.
