Nuclear Reaction Kinetics

Because during fission the length of time between one neutron generation and the next is extremely short it might be expected that controlling a nuclear reactor would be quite difficult.

It indicates how solutions to the point kinetics equation may be obtained for a few simple cases.

Such situations arise during operational changes such as control rods motion environmental changes such as a change in boron concentration or due to accidental disturbances in the reactor steady state operation. This book contains nine chapters and begins with an introduction to some important mathematical theories related to nuclear engineering such as the laplace and fourier transforms. This chapter deals with nuclear reactor kinetics beginning with the onegroup neutron diffusion equation to derive the point kinetics equation.
