This report documents the results of an independent oversight review of the Los Alamos National Laboratory (LANL) Technical Area 55 Plutonium Facility safety class fire suppression system (FSS), concurrent with a scheduled Los Alamos Field Office vital safety system assessment. The review was performed April 29 through May 20, 2013, by the U.S. Department of Energy’s (DOE) Office of Safety and Emergency Management Evaluations, which is within the DOE Office of Health, Safety and Security.  The independent review was one part of a targeted assessment of fire protection at nuclear facilities across the DOE complex, including National Nuclear Security Administration sites.
