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.

NWMO to select Canadian repository site this year
Canada’s Nuclear Waste Management Organization, a not-for-profit organization responsible for the long-term management of the country’s intermediate- and high-level radioactive waste, is set to select a site for a deep geologic repository by the end of the year.

A modular blanket has been proposed for a fusion experimental reactor, such as ITER, to enhance its maintainability as well as improve its fablicability. The blanket module is connected to a strong back plate via support legs protruded from both of the module and the back plate. A welding approach has been investigated for the joining of the support leg that is 70 mm thick to withstand electromagnetic forces and with limited welding/cutting heads working space of 100 mm × 150 mm adjacent to the support leg.
After comparison of several methods, e.g. NGTIG, NGMIG and iodine laser, NGTIG has been selected as a reference for welding and plasma cutting for cutting. Iodine laser has been chosen as an alternative for both of welding and cutting. Through preliminary design studies, the possibility of small welding/cutting heads including their driving systems available to the limited space has been shown. Maintenance route for in-situ module replacement with temporary fixture jigs has been also investigated.
