Nuclear Energy Strategy announced at CNA2026
At the Canadian Nuclear Association Conference (CNA2026) in Ottawa, Ontario, on April 29, Minister of Energy and Natural Resources Tim Hodgson announced that Natural Resources Canada (NRCan) is developing a new Nuclear Energy Strategy for the country. The strategy, which is slated to be released by the end of this year, will be based on four objectives: 1) enabling new nuclear builds across Canada, 2) being a global supplier and exporter of nuclear technology and services, 3) expanding uranium production and nuclear fuel opportunities, and 4) developing new Canadian nuclear innovations, including in both fission and fusion technologies.

The calculation of the resonance escape probability in a lattice by means of a diffusion theory model requires a knowledge of the logarithmic energy width, ln E1/E2, of the resonance absorption region. This quantity is evaluated by fitting the results of a diffusion theory analysis which is averaged over neutron energy to an experimental value of the effective resonance integral. The result is In E1/E2 ≃ 2.6, which is much less than the value 5.6 which is ordinarily used in these calculations.
