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.

Computed disintegration rates and numbers of atoms (abundances) of each fission product radionuclide at various times after simultaneous slow neutron fission of 10,000 atoms of U235 are presented. These results are based on fission yields from two different theories of independent fission yields. The computations treat both known and unknown fission product radionuclides. Half-lives and yields of the latter were estimated. The disintegration rate, number of active and inactive atoms, total number of atoms, and the percentage contribution to total activity and to the total number of atoms are presented for each element and for each chemical group of elements. The disintegration rate of the total fission product mixture according to each independent yield theory is also presented.
