In an ... tests, the norm was around 70-95-pounds/second for reactors which were over 1000+MW, except for the Pewee, which was about half of that at 500MW. The 55-inch Phoebus 2A, still the world’s most powerful reactor at 5000 MW, needed hydrogen at 280-pounds/second. Moreover, don’t worry about the technical feasibility of ...
