Significant Finding Investigations were addressed in DOE/IG-0535 Audit Report Management of the Stockpile Surveillance Program's Significant Finding Investigations December 2001. The Directors of the three nuclear weapons laboratories annually assess and report the condition of the weapon systems for which their laboratories are responsible. A critical event in this process is the identification of a defect or malfunction during surveillance testing. This is especially important when dealing with an aging weapons stockpile. Departmental procedures require preliminary tests or evaluations to establish whether a Significant Finding Investigation SFI should be initiated. Such investigations are then conducted to determine the identified problem's cause and impact and to recommend corrective actions. Weapons surveillance began in the US in the mid-1960s when weapons testing was done through underground explosions of nuclear devices. Such testing continued until the early 1990s. If tests on a weapon system show an anomaly - a possible problem with a part that could jeopardize the system operation - with a system evaluation engineer SEE is notified. It is the SEE's job to determine if the anomaly could affect the surety safe use or reliability of the weapon. If the SEE makes that determination he/she opens a "significant finding investigation SFI. The responsibility of the investigation team is to determine the cause and impact of the defect and to make recommendations for corrective actions.
