What is nuclear reactivity give their advantages
Dear student,
Reactivity is the term given to the quantity that tells you how much the neutron economy is out of balance. If a reactor is exactly critical - that is, the neutron production is exactly equal to neutron destruction - then the reactivity is zero. If the reactivity is positive - then the reactor is supercritical. If the reactivity is negative - then the reactor is sub-critical. The Reactivity is defined as the ratio of an adjoint weighted average of the excess neutron production divided by an adjoint weighted average of the fission production.
