Structural integrity recovery testing

The Reentry Control (REC) process carefully controls work and testing within the SUBSAFE boundary, that is, the structures, systems, and components that are critical to the watertight integrity and recovery capability of the submarine. The purpose of REC is to provide maximum reasonable assurance that the areas disturbed have been restored to their fully certified condition. The procedures used provide an identifiable, accountable, and auditable record of the work performed.
