fission is the splitting of a nucleus into smaller fragments
in a chain reaction, some of the neutrons produced react with other fissionable atoms producing more neutrons which react with still more fissionable atoms
neutron moderation is a process that slows down neutrons so the reactor fuel captures them to continue the chain reaction
fission occurs when nuclei combine to produce a nucleus a greater mass
fusion reactions release much _____ energy than fission reactions more
the potential fuels are inexpensive & readily available
the problems with fusion lie in achieving the high temps necessary to start the reaction
