What you look for in a NPP is a self-sustaining chain reaction, where the original fission releases enough neutrons to cause the rest of the fuel to undergo fission without continuously having to bombard it with more neutrons. But, you don't want the reaction to be uncontrolled - to happen too fast to be able to harness the energy. That is what happens with atomic bombs.
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
