Initially a reactor is operating at a steady-state power level P₀. Using the point reactor kinetics equation with one equivalent group of delayed neutrons, determine the stable reactor period T for a positive step reactivity insertion of 1$. Use the fact that lL/b << 1 to simplify your answer. Calculate a numerical value for T in the case in which l=0.1 sec^-1 and L=0.001sec^-1.
