After those two, DrB proposed to jump straight to the 100MW unit.mrchito wrote: It seems that the "research" at this point can only be done through deployment. A 100 MW reactor is not something intended for laboratory research. I have not seen discussion for any reactors smaller than 100 MW from Nebel's group. And my impression was that their intention was to go straight to deployment, perhaps because it would be impractical to test such a reactor in laboratory conditions if it is intended for municipal power.
MSimon has, with some argumentative support from the rest of us, proposed an intermediate scale unit in order to demonstrate continuous operation, while getting closer to, but not making, break-even. Each of these units is research.
I have modified my position. I think a net power device (on the order of 1 MW) can be done almost as cheaply as a LN2 Cu coil test reactor.
For reasons of speed (and to some extent cost) I'm proposing using off the shelf 3T MRI magnets suitably modified.
