If so, the above numbers don't seem to fit. I could have made a mistake, but by my calculations, if the power increases at a constant Pdot = 160 W/s, then 13.5 L of water (per unit) will begin to boil in t = sqrt(2Q/Pdot) = 40 minutes, not 90. And the power at 90 minutes will be 160*90*60 = 864 kW, and at 13:22, it will be 160*144*60 = 1.4 MW. On the other hand, if boiling begins at 11:00, then the power increase should be Pdot = 2Q/t^2 = 31 W/s, giving a power of 31*144*60 = 270 kW at 13:22. > - From 12:34:40 to 13:22:50 about 631 l (2 l per module) of water has > been boiled off the reactors. > > - At that moment, the pumps are turned on, causing water to flow at a > rate of 675.6 l/h. > > This can be deduced from two facts. > > (1) The temperature of the water in the reservoir starts increasing > linearly from 16.9 at 13:22:50 to 19.6 at 13:56:10 as 375 l of warm > water is pumped back, according to > If the power into the water is 490 kW, then the rate of steam generation (with no inflow of water) is 2.1 g/s per module. This amounts to something like 3.5 L/s per module or 380 L/s total. Since the ecats are not full, water will not flow out of them when the pumps are turned on, and turning them on only adds a volume flow rate of 675L/h = .19 L/s, or 1.8 mL/s per module, which is a tiny fraction of a per cent of the total volume flow rate. In fact, since adding cool water will remove heat otherwise going into steam, the total volume flow rate of steam stays the same (at 490 kW). Therefore this increase in the temperature of the input reservoir cannot correlate with the pump turning on as you describe. There are many other problems, but these two are significant enough to leave it at that. Finally, Rossi and his engineer claim a constant input flow rate for the full 5.5 hours, and this is not an assumption about which they could be reasonably be mistaken (like the output flow rate, or the effectiveness of their trap). What's the point of analyzing the measurements, if you're going to ignore some of them and make up your own?
