A Two-Dimensional Transport Theory Program in a Modular System Environment

摘要

IT is a general purpose two-dimensional, multigroup, multiregion, reactor phsics code capable of solving several approximations of the neutron transport equation. A modular system environment for IT's development has contributed greatly to the incorporation of a large variety of approximations for rectangular, hexagonal, and azimuthally-symmetric geometrical configurations in both the energy and spatial domain. Complementary to its use for obtaining accurate transport theory scalar flux solutions, IT is a research tool for examining the accuracy of various approximations of the transport equations. (Author)
