For super critical transients, it is usually satisfactory to assume that C in the point kinetics equations remains constant during the transient. With this assumption, show that if the reactor is initially critical and at steady state with n(0)=n0 and a reactivity insertion occurs such that =t, then the reactor response is approximately: n0n(t)=e2A2A{1+2e22[Erf(2t)+Erf(2)]}
