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.

In resonance capture calculations, it is usual to assume that the capture in any one resonance is unaffected by the existence of other resonances: this is known as the “flux recovery” assumption. This assumption is exact for hydrogenous moderation in a homogeneous situation. However, in highly heterogeneous lattice cells such as that of the Steam Generating Heavy Water Reactor (SGHW), in which the fuel is intimately associated with a powerful moderator, the resonance flux in the fuel is depressed below that in the bulk moderator. In this paper, this flux depression effect is investigated by using a model in which all moderation is hydrogenous and the resonances are square. This model suggests that the flux recovery assumption will overestimate 238U capture in a typical SGHW Lattice by about 5%.
