Reactor mass flow data base prepared for the nonproliferation alternative systems assessment program

This report presents charge and discharge mass flow data for reactors judged to have received sufficient technical development to enable them to be demonstrated or commercially available by the year 2000. Brief descriptions of the reactors and fuel cycles evaluated are presented. A discussion of the neutronics methods used to produce the mass flow data is provided. Detailed charge and discharge fuel isotopics are presented. U3O8, separative work, and fissile material requirements are computed and provided for each fuel cycle
