Canada begins regulatory approval process for spent fuel repository
Canada has formally initiated the regulatory process of licensing its proposed deep geological repository for spent nuclear fuel, with the country’s Nuclear Waste Management Organization (NWMO) announcing that it has submitted an initial project description to the Canadian government.
According to the NWMO, the initial project description is a foundational document, detailing the repository’s purpose, need, and expected benefits and explaining how the project will be implemented. It also provides a preliminary assessment of potential impacts and describes measures to avoid or mitigate them. The NWMO is the not-for-profit organization responsible for managing Canada’s nuclear waste.

Thin high intensity alpha-particle sources were prepared for the NASA Surveyor Alpha Scattering Experiment. The alpha-active isotope used for this experiment was 242Cm prepared by neutron irradiation of 241Am in a reactor. After irradiation the curium was separated from americium, fission products, and aluminum by liquid-liquid extraction, redox precipitation, and extraction chromatography techniques. The sources were prepared by vacuum sublimation of the curium onto stainless-steel plates, followed by carbon coating from a carbon arc and encapsulation for installation into the Alpha Scattering Instrument.
