Naval Reactors Physics Handbook. Volume 1. Selected Basic Techniques

The purpose of this work is to present the most pertinent parts of the body of physics knowledge which has been built up in the course of the Naval and Shippingport (PWR) Reactor Programs, with the aim of providing a background of understanding for those interested in nuclear core design. Volume 1 of this handbook was planned to bring together topics in the basic theoretical and experimental material which are of especially wide interest, including those common to both thermal and intermediate neutron energy reactor types. The physics design of light water-moderated and -cooled reactors is covered in Volume 2 (classified), and that of intermediate neutron-energy power reactors in Volume 3. The emphasis in Volume 1 is thus on light water reactor systems, and as many recent advances in reactor physics of the Naval and Shippingport Reactor Programs as possible have been included

Void coefficient in a unit cell for U-Pu water breeder reactors

The possibility of breeding with the Pu-U fuel cycle in light or heavy water has been established. For such lattices the void coefficient in a unit cell was calculated. It was found that for light water lattices the void coefficient is negative whereas for heavy water lattices the void coefficient is positive. However, it was shown that by introducing a relatively small amount of light water to the heavy water, a negative void coefficient is obtained while retaining many of the heavy water lattice properties. The results of an investigation of the value of the void coefficient during burnup in a unit cell of the heavy/light water lattices was investigated and the results are presented
