Computerized transportation model for the NRC physical protection project

A computerized model of the transportation system for shipment of nuclear fuel cycle materials is required to investigate the effects on fleet size and composition of changes in shipping requirements, security regulations, work rules, and vehicle capacity. Such a model must be sufficiently general to include all the major features of the transportation system, i.e., those pertaining to both vehicles and personnel. This paper describes the operation and capabilities of a transportation model which has been developed to provide these features. Examples of the results of applying this model to sample shipment schedules are presented. 2 refs
