An atomic bomb differs from a nuclear power plant in that the former?
1. contains more fissionable material.
2. involves a chain reaction.
3. produces less energy but more heat.
4. contains more moderating material.
5. contains a critical mass of fissionable ma-
terial.
Also why??? that’s what i’d like to know more
An atom bomb and power plant function by exactly the same means. A chain nuclear reaction. So 2 is out. The difference is that the power plant contains control rods, which absorb excess neutrons, preventing the exponential run-away reactions seen in the bomb. so 4 is out. Atom bombs actually contain very little fissionable material, so 1 is out. heat IS energy, so 3 is obviously wrong, and that leaves us with 5.
a “critical mass” is a point where the fissionable material is so dense, that it will spontaneously begin to undergo fission. The close packing of the atoms, means that the neutrons produced will almost certainly split other atoms resulting in the run-away reaction, and hence a nuclear explosion. If power plants contained critical masses of fissionable material, then every city with one would end up like Hiroshima.
