ABSTRACT
Thus far, our discussions have focused on xed-source problems that are observed in the areas of radiation shielding, dosimetry, and nuclear security. In this chapter, we will introduce the Monte Carlo method as applied to eigenvalue problems that are encountered in reactor physics as well as nuclear safeguards and nonproliferation. The major difference between the two problem types is that, in the eigenvalue problems, source distribution is unknown and, therefore, there is a need for an extra layer of computation to obtain the source distribution.
