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.
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.

Cs-137 sealed source lost in Western Australia

Authorities are searching 1,400 kilometers (870 miles) of Australia’s Great Northern Highway, between Perth and the remote town of Newman, for a lost sealed-source capsule containing cesium-137. The source was part of a density gauge used by mining company Rio Tinto at its mining operations in Western Australia.
The Department of Fire and Emergency Services (DFES) of Western Australia reported that the density gauge containing a 6-mm-diameter (0.24-inch-diameter) by 8-mm-height (0.31-inch-height) source capsule was sent by flatbed truck to Perth for repair, leaving Rio Tinto’s Gudai-Darri mine site in Western Australia on January 12 and arriving in Perth on January 16. The package containing the gauge, however, was not inspected until January 25.
Upon opening the package, it was found that the gauge was broken apart with one of four mounting bolts missing. The source itself and all screws on the gauge were also missing. It is assumed that vibrations from the truck broke the gauge apart and allowed the screws and capsule to fall through the bolt hole and away from the truck. DFES said they were notified of the loss on the evening of January 25.

Advanced nuclear systems, such as fusion systems, generally have features of large size, complex structures, spatially heterogeneous distribution of components and materials, and high energy and high flux, as well as a wide and complex energy spectrum of neutrons. Compared with traditional nuclear systems, these features have brought unprecedented challenges to neutronics design and analysis. To confront these challenges, the FDS Team has made significant progress in the development of neutronics methods and the comprehensive simulation code Super Multi-functional Calculation Program for Nuclear Design and Safety Evaluation (SuperMC). Furthermore, the FDS Team has been developing the High Intensity D-T Fusion Neutron Generator (HINEG) and has performed a series of neutronics experiments. Based on the developed methods, codes, and facility, a series of fusion designs and analyses has been carried out, including the design of FDS series reactors as well as the ITER neutronics analysis.
