OMG....
First if your going to correct me at least bother to read my words correctly. I said nuclear plant, which is not by definition electricity producing, in this case it was merely there for research. Furthermore, the first continuously operational fission reactor was created in 1942. The reactor became supercritical on December 2, 1942 in the squash court at the University of Chicago. A fun and scary story, the used lower classmen as "suicide" workers in the event of an emergency. They were to run in with buckets of cadmium sulfate in the event of fire or core meltdown. Also, the first nuclear power plant producing electricity came in 1951 on a military installation. The first commercial power plant came in 1954, a small prototype built in the Soviet Union. Nuclear reactors are also, for the most part, steady state, they do not process "batches" of neutrons. They do however operate under power/feedback cycles of fluctuating power output. You want to argue schematics that's fine, the rest of it your way of base....
