The anatomy of a program to develop a first nuclear weapon was analyzed as a precursor to comparison of potential counter-proliferation activities. In this talk we discuss this precursor task. The weapon and path selected for this analysis was covert development of a gun-type fission device using uranium enriched by centrifuge technology. The rationale for this selection is described. The anatomy was developed by identifying and sequencing each task required to ultimately assemble a single working nuclear explosive device and to provide a limited follow-on production capability. Tasks involve acquisition of materials, design and development of components including manufacturing tools and equipment, design and construction of facilities, operation of the facilities, assembly and integration of the components, and test and evaluation of the components and assembled device. Critical aspects of these steps will be discussed in the presentation. For each task the resources required (time, manpower, utilities, feed materials, and equipment) and their associated costs were estimated. These were inserted into standard project management tools. This permitted easy determination of overall costs and program duration as well as establishing a critical program path. The significance of this information and its use in one potential counter-proliferation activity is described as are potential extensions of this process to analysis of other proliferation pathways.

Robert C. Harney is an associate professor of systems engineering at the Naval Postgraduate School and is the Naval Sea Systems Command Chair of Total Ship Systems Engineering (Combat Systems). He received the BS degree in chemistry and physics from Harvey Mudd College in 1971 and the PhD in applied science from the University of California, Davis in 1976. His entire career has been spent in the field of national defense, working at Lawrence Livermore National Laboratory, M.I.T. Lincoln Laboratory, and Martin Marietta Corporation before joining the Naval Postgraduate School in 1995. He teaches courses in sensor systems, weapon systems, and systems engineering. His primary research interests are in advanced sensor systems, unconventional weapons of mass destruction, and counter-terrorism.
