The Canadian Nuclear Safety Commission (CNSC) has granted a license to Ontario Power Generation (OPG) to construct a small modular reactor (SMR) at the Darlington New Nuclear Project site in Clarington, Ontario. This marks a significant milestone for Ontario and Canada, as the project is set to be the first of its kind in the G7. The SMR, a General Electric Hitachi BWRX-300 reactor, is aimed at providing reliable, affordable, and emissions-free energy to power the province. The project is projected to create up to 17,000 jobs during construction and contribute over $15 billion to Canada’s GDP, with a considerable portion going into the local supply chain. The BWRX-300 reactor is praised for its innovative and simplified design, offering cost-competitive solutions for various applications, including hydrogen production. With a capacity to provide 300 MW of carbon-free power, the reactor comes with digital features that enhance safety and reduce costs. Its self-cooling capability for seven days without power showcases its resilience. Additionally, the construction techniques employed reduce building volume by about 50 percent per MW, resulting in significant cost savings and efficiency improvements. The project has undergone environmental assessments and has been deemed unlikely to cause adverse effects, further solidifying its contribution to Canada's energy landscape and economy.
