Hi Bob;
I’m trying to get my head around the hardware pieces but I’m clearly missing something. I think I have a bit of understanding of the “fuel processor”. but I have some confusion about what goes on top of the “processor”. Is it a cap of some sort? Another transducer and tube? He talked about water flow at some point when pointing at the holes around the opening where the fuel slug and heater slug go.

The drawing you posted doesn’t really match the stainless cube at the focus of the transducers, so I haven’t fired up my milling machine yet… ;-)

Does this “processor” assembly have anything to do with the reactor portion? You talk about the water supply as being ambient temp and pressure but I haven’t seen any coolant piping except where the steam exits. I wish you had followed that steam line to the reactor. In fact from the “water tap” to the steam exit.
