Reactor Photon

if each fission causes one additonal fission you have a?

a. sun
b. storm
c. power reactor
d. photon clock
e. bomb

some incorrect answers, and some difficult to read.

In a nuclear bomb, you need a chain reaction, where every fission causes MORE than one additional fission, preferably 2 or 3.

But in a nuclear fission reactor, you want to control the chain reaction so that it does NOT explode, and you do this via a moderator that absorbs some of the neutrons, and the resultant neutron production rate is 1 for 1.

so c is the answer.

The sun uses fusion, not fission.
