Reactor physics

This textbook is prepared for a lecture of the reactor physics in Nuclear Professional School of The University of Tokyo. In Chapter 1, the characteristics of nucleus and the interaction between nucleus and neutron were described. In Chapter 2, the fission reaction, its chain reaction and a concept on criticality were described. Chapter 3 described about the fundamental study on a diffusion equation to treat the neutron spatial distributions in a substance. In Chapter 4, the application of a diffusion equation was shown to learn the feature of neutron distribution in a substance with homogeneous composition. Chapter 5 described the physics of neutron slowing-down in a substance and Chapter 6 investigated the neutron slowing-downed to become in thermal equilibrium state in the substance. Chapter 7 considered the effect of the practical heterogeneous composition from the homogeneous one to the criticality. The JENDL-4.0 library was referred for the nuclear reaction cross section data.
