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.

Currently, there is an ongoing international effort to develop and characterize W alloys that are suitable for fusion applications. In this report, five key W alloys were examined for the advanced divertor design of ARIES-ACT - the latest ARIES tokamak design. The most promising alloys appear to be W-1.1TiC and W-La2O3. At the end of the divertor lifetime (~4 years), the maintenance dose of these alloys very closely matches those of W with nominal impurities. Unfortunately, even with pure W, the divertor is not clearable, which indicates that it must be recycled or disposed of in a geological repository. The radiation damage and transmutation are expected to degrade the physical properties of any material. The radiation damage level in W is low compared to ferritic steel - a remarkable feature for tungsten. For ARIES-ACT operating conditions, transmutation of W does not appear to present a significant issue.
