I'm glad the bear case includes the "will never be economically practical" which is my core criticism of fusion, even with "high funding".

I also didn't see anything about vessel irradiation, which also never seems to be discussed. I get it probably isn't as big a problem as solid fuel rod fission in terms of waste creation, and tritium breeding may help, but it still will be kind of the same problem with LFTRs: a reactor design will fundamentally need an ongoing reconstruction/replacement strategy due to the vessel irradiation and transmutation from high energy neutrons.

Feel free to correct me if this isn't as big a problem as I think it is.
