Do you really have a PhD?
About the reactor needing/consuming 2.2 tonnes of plutonium each year, the point is we do not want to start shipping tonnes of plutonium all over the world.
Besides the hijacking risk, there are lots of countries that might want a newly designed safer reactor. Maybe those countries can not be trusted with grams of plutonium let alone tonnes of it each year.
Enriched fissile-capable uranium is extremely hard to make. But once you've got plutonium, you got a a-bomb ready to go save a good implosion design. Once you got plutonium and a good implosion design and a good tank of heavy hydrogen, you've got a megaton hydrogen bomb.
Plutonium can only be used in countries that already have significant nuclear weapons already.
Yes. Here's a quote from a REAL nuclear science text (Basic Nuclear Engineering, by Foster and Wright).
"Fission occurs when a fissionable nucleus captures a neutron. Capture upsets the internal balance between neutrons and protons in the nucleus. The nucleus splits into two lighter nuclei, and an average of two or three neutrons is emitted. The resulting mass of products is less than that of the original nucleus plus neutron. The difference in masses appears as energy in an amount determined according to Einstein's forumula, E=mc2."
