I would really like to see what the screen on top of the PLC was
displaying. All the answers to our engineering control questions could
be on that screen. It sure looks like the box was very full of controls
of various types and kinds.

Ooops... my intuition screwed up on this one:
Since the effective specific heat does not remain constant with
temperature -- there is a discontinuous rise at the boiling point
-- there is a dramatic rise in the effective heat transport with
temperature at the boiling point (whatever it is for the pressure
in the reaction vessel).
That's all that's required for temperature control. Rossi's
effort required to achieve self-sustained mode then would have
been to ensure that the flow rate around the reactor vessel was in
the range where it is low enough not to quench the reaction in the
1deg/gm/calorie regime, but high enough that in the regime where
its some huge number the reactor reaches an equilibrium with the
heat transport.
I plead lack of sleep.
