Actually the tiny amount of Candu nuke waste is the same level as high grade uranium ore after a few hundred years. Stuff it in an old uranium mine - nobody would notice. 

All in including refurb and decom, the real cost of new public power nukes based on the last 7 Candu's built all on time on budget, is 3 cents a kwh - cheapest energy there is.

All wind/solar manufacturing efficiency are in with costs now primarily in labor and related materials, and low prices sustained by Chinese dumping from 100% subsidized production facilities giving venture capital funded projects real unsubsidized costs of near 40 cents a kwh for solar, all 15 for wind. The Ontario AG added a further 35 cents a kwh for up to 10 times transmission needs, gas backup, and dumping. Add a further 3 bucks a kwh for the cheapest envisioned battery backup.

Its ironic how Trump's fake fact, alternative truth, methodology got its start with "green" energy advocates.
