You have gone to a lot of trouble to argue that the reason the temperature is so well regulated, as in perfectly flat, is because the reactor is only heating liquid water directly, like in a teapot. If that's so, then how does the steam get heated above the boiling point? The perfect regulation is a much more reliable indication that the fluid is at the boiling point than any evidence you can get from a probe that measures temperature and pressure. As for why the probe reads above the expected boiling point, one can suggest (1) impurities in the water, (2) slightly elevated pressure in the ecat (because of the production of steam, and the required flow rate), (3) errors in the measurement, and (4) placement of the probe with respect to heating elements, or copper tube, which may be a little hotter than the fluid.
