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.

Zaporizhzhia ‘extremely fragile’ relying on single off-site power line, IAEA warns
Europe’s largest nuclear power plant has just one remaining power line for essential nuclear safety and security functions, compared with its original 10 functional lines before the military conflict with Russia, warned Rafael Mariano Grossi, director general of the International Atomic Energy Agency.

The Applied Radiation Physics Group at Culham Centre for Fusion Energy, United Kingdom, has developed and applied state-of-the-art radiation mapping methods and tools. The tools enable complex shielding calculations in and around fusion devices, both during and after plasma operations, to inform on associated radiation fields for operational, maintenance, and remote handling scenarios, for example. Here, we present a description and application of those tools to produce radiation maps to support (a) the Joint European Torus (JET) operational safety case for a new D-T campaign that is foreseen for 2020, with neutron emission rates in excess of 1018 n/s and a total neutron yield up to 1.7 × 1021 n, and (b) the ITER device.
Three tools are presented in this paper: An automated global variance reduction tool applied to the JET facility; a portable bounding surface source referred to as a mesh source, which has been applied to activated materials; and a smeared source routine, which enables the calculation of integral fields associated with moving sources. These tools are demonstrated, in combination, to produce the integrated three-dimensional dose map of an activated divertor component being transported through a path within the ITER facility.
