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.

It is proposed to use the (γ, n) reaction for the measurement of the integrated void volume fraction in two phase flow of D2O inside a duct. This method is applicable to different channel geometries, and it is shown to be insensitive to the pattern of void distribution over the cross-sectional area of the channel. The method has been tested on mock-ups of voids in a round duct of 6 mm inside diameter. About 40 mC Na24 was used as a source of gamma rays. The test results show that the maximum measured error in this arrangement is less than 2.5% (net void) for a range of 2.7% to 44.44% actual void volume fractions.
