Now you can parse all of this information and look at the images of the size of the reactor which are small - and estimate how much weight of material for 'many channels' is possible. The report which I was made aware of did this, and as you can see - I am far from being an expert in thermodynamics, so it is not my conclusion, but nevertheless - it should be a part of the recordÂ… anyway, it was claiming that there was neither room nor extra mass for fins or channels. I listed that as the caveat. Rossi also says the water flow is straight thru.

Straight through what? I'm not sure what that means. The air flow is "straight through" an automobile radiator, but it has many channels. Does the water come into contact with the nickel? If it does, this might be very simple. If not, there must be channels, but they could be very thin.

If the heat generation rate would be 30+ kcal/sec as you state and a flow rate of a liter per second and a delta T of ?? then it should be possible to guesstimate the surface area necessary, for those variables - given the known conductivity of stainless.

Would you agree so far ?

Yes, it should be possible to estimate a minimum. The material for the channels is unknown. The thickness of the tubing (internal) is unknown, is it? What is are the channels or tubing made of? You seem to be assuming stainless steel why? Copper? How is the heat transfer to the coolant arranged?
