Education and training to support Canadian nuclear workforce development
Along with several other nations, Canada has committed to net-zero emissions by 2050. Part of this plan is tripling nuclear generating capacity. As of 2025, the country has four operating nuclear generating stations with a total of 17 reactors, 16 of which are in the province of Ontario. The Independent Electricity System Operator has recommended that an additional 17,800 MWe of nuclear power be added to Ontario’s grid.

A shattered pellet injector (SPI) based on in situ technology was developed in the HL-2A tokamak. In this paper, the basic principle of pellet formation is introduced, the mechanism of a SPI is described in detail, and test results are presented. Bench test experimental results show that reliable formation and acceleration of a large nitrogen pellet (diameter of ∼3.5 × 4 mm) were obtained. A double-impact tube was developed and tested for effective and reliable shattering of the pellet.
