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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

What is next for Canada’s deep geological repository project?
Gierszewski
In late 2024, Canada’s Nuclear Waste Management Organization announced the selection of a site in northwestern Ontario for its deep geological repository for the country’s used nuclear fuel.
This is a major step in a plan that was first laid out in 2010. From the beginning, the plan had been clear that any selected site must be technically safe, must be accessible for fuel transportation, and must have informed and willing host communities.
By 2020, potential sites had been narrowed from an initial set of 22 communities that had indicated interest in learning more down to two specific sites.
My primary involvement was on the technical safety side. We wanted to know that we could safely build and operate the repository at the chosen site.

Radiation-induced evolved gases for 20 commercial lubricant base oils were measured at room temperature. Samples were irradiated under vacuum by 60Co gamma rays at a dose rate of 1 Mrad/h up to 1000 Mrad for mineral oils and ester lubricants, and 3000 Mrad for aromatic lubricants. The evolved gas was measured by means of gas chromatography. The G values (number of gas molecules liberated per absorbed energy of 100 eV) of total evolved gases are 2.8 for liquid paraffins, 1.4 for paraffinic neutral oils, 1.5 to 1.9 for esters, 0.26 to 0.56 for alkyl diphenyl ethers, and 0.005 for phenoxy-phenoxydiphenyl
