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.

TerraPower begins U.K. regulatory approval process
Seattle-based TerraPower signaled its interest this week in building its Natrium small modular reactor in the United Kingdom, the company announced.
TerraPower sent a letter to the U.K.’s Department for Energy Security and Net Zero, formally establishing its intention to enter the U.K. generic design assessment (GDA) process. This is TerraPower’s first step in deployment of its Natrium technology—a 345-MW sodium fast reactor coupled with a molten salt energy storage unit—on the international stage.

Experiments on induced activities in type 316 stainless steel (SUS316) have been performed to verify an induced activity calculation code system, THIDA, by using the FNS facility. Samples of 10 mm φ × 2 mm t SUS316 were irradiated in three different D-T neutron fields. One sample was positioned at 10 cm from the target without any assembly around it and the other two placed inside the Li2O-C pseudo-spherical blanket assembly. After the irradiation, spectra of gamma-rays emitted from produced activities in each sample were measured by using a 60 cm3 Ge(Li) detector following the cooling times from 10 min. to about one month. The gamma-ray spectra were compared with those calculated by THIDA. All measured total gamma-ray intensities agreed with calculated ones within 15 % except one case. Though there are some disagreements in the individual gamma-ray intensities, the agreements are good as a whole.
