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.

The fission cross sections of 235U for neutrons having energies between 0.2 and 8.2 MeV have been measured with neutrons from the 7Li(p, n) reaction. The neutron energy scale was calibrated by the 7Li(p, n) and 10B(p, n) neutron thresholds, and the flux was measured with a black neutron detector. The fission cross sections, averaged over the 252Cf fission neutron spectrum, were determined as 1.202 b, with an uncertainty of 2 to 3%.
