Establishing Sitewide Risk Perspectives Due To Cumulative Impacts From Ab Ep And Nepa Hazard Analyses

With the end of the Cold War in 1992, the mission for the Rocky Flats Environmental Technology Site (Site) was changed from production of nuclear weapon components to special nuclear materials (SNM) and waste management, accelerated cleanup, reuse and closure of the Site. This change in mission presents new hazards and risk management challenges. With today's shrinking DOE budget, a balance needs to be achieved between controlling those hazards related to SNM and waste management and interim storage, and those hazards related to accelerated closure of the Site involving deactivation, decontamination, and decommissioning (DD and D) of surplus nuclear facilities. This paper discusses how risk assessments of normal operations and potential accidents have provided insights on the risks of current operations and planned closure activities.
