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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

The Omega Upgrade at the Laboratory for Laser Energetics will commence deuterium-tritium (DT) shots in 1995. Omega Upgrade utilizes a 350 nm, 30 kJ laser to energize DT filled targets contained within an evacuated target chamber (TC). Up to 10 DT shots per day are planned, 5 days a week, with each target containing 20 mCi of tritium. Cryopumps, used to achieve high vacuum in the TC and to collect unburnt gases following DT shots, are regenerated on a monthly basis. The Tritium Scrubber System (TSS) has been designed to capture tritium released from the cryopumps, vacuum pump exhaust streams, outgassing from internal surfaces, and in the event of target rupture. A large quantity of low activity gas needs to be processed by the system; the target chamber and diagnostic antechambers will be evacuated up to 8 and 2000 times each month, respectively. The TSS has been designed to interface with existing equipment at the facility. To permit the safe handling of tritium gas products and to comply with emission regulations, modifications are required to the facility to enable the capture of tritiated species from exhaust streams before being released to the atmosphere. The targeted annual tritium emission for the facility is less than 10 mCi. The TSS utilizes zirconium alloy hydride beds and molecular sieve beds to detritiate exhaust streams prior to stacking to satisfy this stringent emission target.
