But why build them in Darlington, when there's a big grid that could make use of new CANDU reactors, for which most of the supply chain is from Canada and its higher energy output makes it more competitive?
One of the perks of building them in Darlington is that the regulatory approval process is simpler since there's already nuclear facilities on site. Saskatchewan is currently going through the site selection and approval process and will be doing that for a while while the BWRX-300 units are going up in Darlington. The build in Darlington and lessons learned will be applied directly to the SK BWRX-300 builds.
BWRX-300 makes more sense in smaller communities.
