Available in PDF, EPUB and Kindle. Book excerpt: TRIXY is a computer program that provides a multigroup analysis of nuclear reactors in three space dimensions. The program can be run on an IBM 704 computer that has at least 8192 words of memory and six tape units. The input data consist of cross-sections, geometrical configurations describing the location of material within the reactor, control rod positions, mesh spacing for the three axes, and boundary conditions. For each energy group, g, the program computes phi, the neutron flux, by a numerical approximation to the age- diffusion equation. When phi has been calculated for all groups, the fission source is computed. The criticality and source error are calculated and printed.
