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.

High-temperature, gas-cooled, graphite-moderated reactors of the type represented by the HTGR feature a continuous removal of volatile fission products by, and their subsequent trapping from, a helium purge stream. Cesium is a volatile fission product of considerable interest; therefore, an investigation of the specific sorption (gm Cs /gm C) of activated charcoal as a function of temperature and pressure was undertaken. The experimental approach was to use Cs137-tagged metal of known specific activity whereby the amount of cesium sorbed on charcoal could be determined in situ by a calibrated gamma-ray spectrometer system. Cesium adsorption on activated charcoal was found to follow the Freundlich adsorption equation. Isosteric heats of adsorption are given as functions of specific adsorption. The free energy of adsorption was found to be a linear function of the specific adsorption only, thus leading to a method of determining the adsorption isobars and isotherms from a minimum of data.
