Well you -LSB-'ve] got to have this design around it, what's the called blanket; and what the hope is, is that the neutron will go
out and the blanket is made
of some very thick steel - type material, and every so often, a neutron will just hit an atomic
nucleus in the steel blanket and that hit will then make the steel hotter and that hot steel, and then you have, almost like
in a car engine, you have some fluid, water could work, going through the steel, it takes the energy away, that water is hot, it goes and spins the turbine, okay that's great.
