WebStart a chain reaction, or introduce non-radioactive isotopes to prevent one. Control energy production in a nuclear reactor! (Previously part of the Nuclear Physics simulation - now there are separate Alpha Decay and Nuclear Fission sims.) Sample Learning Goals Describe how a neutron can give energy to a nucleus and cause it to fission. WebAnswer (1 of 7): A nuclear fission bomb needs a switched neutron source. Before a fission bomb is detonated, neutrons will appear in its core now and then, mainly from spontaneous fission of the fissile material, but also from cosmic rays and the mild radioactivity of almost everything. A neutro... example of cyber risk
