Title: RAPID TRANSIT--A REACTIVITY SURVEY PROGRAM FOR THE IBM-704

Technical Report ·
DOI:https://doi.org/10.2172/4257148· OSTI ID:4257148

>The program described computes the reactivity changes associated with slurry settling in a one-region cylindrical slurry reactor. Nuclear-data computation has been included in the program in order to avoid tedious hand calculations and to reduce the amount of input data required. About 3000 cases may be processed pcr hour of machine time. Certain modifications to the conventional two-group method and techniques employed in improving the rate of convergence of certain iterative procedures are discussed in detail. Sample input sheets, output sheets and instructions for input data preparation are included. (auth)
