Wikipedia?! Really?!?
Even it admits, “No precise definition of a Generation IV reactor exists.” Much less a selected candidate... Much less commercial plans... Much less getting through the licensing and public comment process... Much less getting past all the lawsuits and legal roadblock from leftists... Much less a company actually deciding to build such a plant.
In fact a solution for nuclear waste has been know since the 1980s, but politicians and kakistocrats have thwarted the solution at every turn, eventually demanding scientists accurately predict the stored rad waste safety for the next one million years.
And the billions of $$$ from a surcharge on ratepayers for their electricty generated by nuclear power for the last four decades to find a waste storage solution? It’s been spent.
Thanks, glad I could help:)
