Modification of the Leopard Computer Program in Order to Improve Isotopic Inventory Prediction Accuracy

Periodically, it is necessary for personnel at a nuclear generating station to know such factors as the isotopic composition of reactor fuel in order to meet inventory and shipping requirements. In addition to this type of information, quick checks of reactor parameters are also often required. A large variety of computer programs exist for these purposes. These programs vary in accuracy, complexity, and required computer size and computer time. Often time is not available for lengthy data preparation and lengthy computer use scheduling. In order to cope with this type of a situation, a fast running and relatively accurate method of calculating reactor parameters is needed. The computer program Leopard is such a program.
