that IF DPF works as desired, if not energy multiplication from fission of waste and of course heat engines will be needed to achieve energy positive function. I would argee deep sea storage is a great option in theory but politically it a nightmare all the environmental groups would have a orgasm of outrage, you could more easily convince them with destroying nuclear waste then storing it where it could leak out (no matter how unlikely that is, they will cry murder over it)

We are kind of working on the FF/DPF assumption, here. And subduction zones are those areas where the ocean floor is being drawn down beneath the continental plates, and merging with the mantle. Lots and lots of half-lives later, some of it may resurface in volcanic lava, but it is LITERALLY millions of years.

Pandering to public ignorance must come to an end somewhere.

I read the SciAm article on deep sea storage of nuclear waste so I understand what your saying in enough detail to agree. But if your running on the assumption that DPF/FF/F2 works I’m being a little more pragmatic, it might end up being nothing more then a neutron generator. Now if it does work as described there is still going to be needs for medical and industrial radionuclides, fusion driven fission and neutron capture of heavy actinides could manufacture them more cheaply then exiting reactors, mind you there is only a few such reactors in the work of supplying radionuclides, but when they eventual shut down something going to need to replace them, now I never said fusion driven subcritical reactors would become the norm, but they would exist if only a handful of them even in a fully successful F2 economy,and if F2 is not that successful fusion driven subcritical reactors would likely be more economical.
