Conventional explosives assemble a subcritical mass of fuel into a supercritical mass, which takes about 1ms.
A burst of neutrons are injected into the supercritical mass at an optimal time from a pulsed neutron source.
In a Uranium fueled bomb:
n + U235 --> FpX + FpY + (2 to 3)n + ~195 MeV, (where X 1.5Y and 233 X + Y)
In a Plutonium fueled bomb:
n + Pl239 --> FpX + FpY + (2 to 3)n + ~200 MeV, (where X 1.5Y and 237 X + Y)
This cycle takes 1 "shake" (~10ns) and it repeats over and over until the release energy causes the supercritical mass to disassemble back to subcriticality, which takes ~100 "shakes" (1us).

What type of reaction happens inside a nuclear power plant?
A nuclear chain reaction nuclear fission
What term describes the reaction process in a fission reaction?
another name for nuclear fission is: E=MC squared
What type of reaction happens in a nuclear power plant?
Nuclear fission
For a chain reaction occur each fission must produce at least ____more fission reaction?
its 1 i think
What is the continuous bombardment and splitting of a atomic nuclei?
A nuclear fission chain reaction
What type of reaction happens inside a nuclear power plant?
A nuclear chain reaction nuclear fission
What type of reaction happens inside a nuclear plant?
A nuclear chain reaction nuclear fission
How is fission inside a powerplant controlled?
The fission is controlled by inserting rods made of a material that absorbs the neutrons. This keeps the reaction from continuing, or slows the chain reaction.
When was fission reaction invented?
The first time a fission chain reaction was produced was in 1942
What term describes the reaction process in a fission reaction?
another name for nuclear fission is: E=MC squared
What particle is used to start nuclear fission?
In actuality, a spontaneous fission event begins a nuclear chain reaction. It kick starts a nuclear chain reaction. And a neutron from that fission will initiate another fission to continue and rev up that nuclear chain reaction.
What is it called when nuclear fission is repeated?
It is called nuclear chain fission reaction.
If For a sustainable fission reaction each fission must produce exactly how many additional fission reaction(s).?
To sustain a fission chain reaction, each fission reaction must result in one more fission reaction. And that one should result in one more, and so on.
What type of reaction happens in a nuclear power plant?
Nuclear fission
Is nuclear fission a chain reaction?
Not of itself, but it can be made to be.
Which describes what happens during a chain reaction?
Neutrons released during a fission reaction trigger other fission reactions.
An ongoing series of fission reactions is called a (n) .?
Fission and fusion reactions are chain reactions but in different ways. In fission reaction a heavy nuclei is bombarded with a slow moving neutron and this nuclei breaks to produce more such neurons along with generation of new elements. These slow moving neutrons are further used to carry out fission of more such nuclei. This is chain reaction. Fusion reaction are a different class of nuclear reaction in which small nuclei fuse together to produce bigger nuclei along with the generation of energy due to mass defect.. In fusion reaction lot of energy is produced and this energy is used to carry out further reaction. Thus both can be called series reaction.
