Geometric buckling is a measure of neutron leakage and material buckling is a measure of the difference between neutron production and neutron absorption. When nuclear fission occurs inside of a nuclear reactor, neutrons are produced. These neutrons then, to state it simply, either react with the fuel in the reactor or escape from the reactor. These two processes are referred to as neutron absorption and neutron leakage, and their sum is the neutron loss. When the rate of neu… WebOct 19, 2024 · A containment of a nuclear power plant is a final barrier against the release of radioactive materials and withstands internal pressure due to an accident.
