I mean an SMR is only half the nominal core size of a CANDU6, most of the literature calling them dramatically smaller is comparing to 1+GW reactors.
More reactors spread around the province means diluting expertise ( let’s be real there are only so many people qualified to run these things, and frankly I want our best minds keeping an eye on things not the b team because we wanted 6 teams ), miltiplying dilutive costs ( security ).
SMR’s and Gen3/3+ Reactors share very similar safety concepts ( the big one is ability for passive cooling ), and considering an accident is an unacceptable event having a bunch of statistically improbably events that need to be managed seems like a terrible idea compared to focusing our efforts on one or 2 plants.
I’d personally rather we just didn’t things right and take ourselves seriously as a country rather than this pussyfoot approach.
