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.

We discuss the technology developed at the Lebedev Physical Institute for the manufacture of hollow microspheres polyethylene terephthalate (PETP). The microspheres are produced by means of foaming solid PETP granules containing CO2 blowing agent in a vertical free-fall furnace. The diameter of obtained microspheres ranges from 50 to 800 µm, with aspect ratio typically from 10 to 50. Reasonably high maximum rupture strengths and relatively low permeabilities have been measured. These properties allow PETP microspheres to be used for long-duration storage of gases and in the technology of cryogenic targets for the ICF program.
