Production Risk Evaluation Program (PREP) - summary

Kjeldgaard, E.A.; Saloio, J.H.; Vannoni, M.G.

Nuclear weapons have been produced in the US since the early 1950s by a network of contractor-operated Department of Energy (DOE) facilities collectively known as the Nuclear Weapon Complex (NWC). Recognizing that the failure of an essential process might stop weapon production for a substantial period of time, the DOE Albuquerque Operations office initiated the Production Risk Evaluation Program (PREP) at Sandia National Laboratories (SNL) to assess quantitatively the potential for serious disruptions in the NWC weapon production process. PREP was conducted from 1984-89. This document is an unclassified summary of the effort.
