Possibly, but it seems exceptionally expensive and slow for what you get.

Sods law will say if you don't invest in nuclear, you'll be using a lot more CCGT because storage or large-geography interconnects won't be there

But if you do invest, you'll end up being stuck with something costing far more than commodity renewables+storage

We have "workable fission" now, it's just very expensive. Workable fusion is always a generation away.
