Nuclear energy production is unable to control the nuclear chain reaction and segregation to occur at a rate that is suitable. Makes it possible to bring the energy of heat radiation and neutron that happens to be useful.
Is a nuclear power and can control the separation of nuclear chain reaction to occur at a rate sufficient. It can take the heat and neutron radiation happens to be helpful.
Is the machine to produce nuclear power can be controlled nuclear chain reactions, separation and occur at a rate of moderation. It can bring the heat energy, neutron radiation and was going to use it.
