I originally surmised heat exchanger fins on the bottom, but several vorts insisted that there is no evidence for heat fins on the bottom and that the reactor cell is bolted to the bottom (but I didn't show bolts). So I removed the fins on the bottom.
Your comment about the internal water flow is interesting. I will consider how to represent that input. I presume when you say "hot input" you are referring to the top T fitting that is the water/steam outlet. Where is the evidence that it "IS" 3 bar? Have you identified the part used? The operating steam temperatures are more consistent with operation at ~1 bar gauge. I thought it sufficient to simply mark it as "~1", but if there is evidence that it could be as much as 3 bar (gauge or absolute?) then the figure will need to be revised. I don't really have a problem with adding the ? though. If the internal pressure really is 3 bar gauge, then the reactor must be operating full of water and it is probably superheated liquid water that exits the hot outlet and flashes to steam as it exits into lower pressure, cooling some of the water around it and causing a water/steam mix in the output.

In the original tubular ecats the lead was probably in contact with the copper pipe. I would expect the bottom lead to need fins. (I'd put them back, with a "?") Unless .... see comment c) b) Lead should surely surround the wafer. c) Rossi has said that the 3 cores are in SERIES, and then the fat-cats are connected in parallel. This would imply that water is injected into the wafer, not the tank, and then goes through three wafers. d) There IS a 3-bar pressure relief valve at the hot input to the heat exchanger. The 1-bar should be marked "?"
