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.

Nike is a large angularly multiplexed Krypton-Fluoride (KrF) laser under development at the Naval Research Laboratory. It is designed to explore the technical and physics issues of direct drive laser fusion1. When completed, Nike will deliver 2–3 kJ of 248 nm light in a 4 nsec pulse with intensities exceeding 2 × 10 14W/cm2 onto a planar target. Spatially and temporally incoherent light will be used to reduce the ablation pressure nonuniformities to less than 2% in the target focal plane. The Nike laser consists of a commercial oscillator/amplifier front end, an array of gas discharge amplifiers, two electron beam pumped amplifiers (one with a 20 × 20 cm2 aperture, the other with a 60 × 60 cm2 aperture) and the optics required to relay, encode, and decode the beam. Approximately 90% of the system is operational and currently undergoing tests: the system is complete through the 20 cm amplifier, the 60 cm amplifier has completed all the necessary electron beam/pulsed power tests, and is currently being developed into a laser amplifier, and most of the optics have been installed. It is anticipated that Nike will be fully operational in the fall of 1994.
