The Jefferson Lab Accelerator Safety Program is used to analyze the hazards associated with accelerator operations and provided a description of the associated mitigation methods. All hazards associated with operations at Jefferson Lab are analyzed using "worst-case" scenarios associated with credible, but hypothetical events; these include accidents initiated by natural phenomena. From these analyses, engineered and administrative controls, including limits on key operating conditions for the CEBAF, LERF and UITF accelerators, are developed. Primary controls, that ensure safe accelerator operations within the associated Accelerator Safety Envelope (ASE), are identified, documented and approved by the DOE. Operation within the safety envelope provides an adequate assurance of safety for workers, the public, and the environment.
In compliance with the requirements of the Department of Energy (DOE) Accelerator Safety Order (ASO), DOE O 420.2C, this Final Safety Assessment Document (FSAD) provides a qualified safety assessment of the hazards specific to the operation of the Continuous Electron Beam Accelerator Facility (CEBAF), the Low Energy Recirculator Facility (LERF), and the Upgraded Injector Test Facility (UITF).
DOE Order 420.2C Safety of Accelerator Facilities defines and establishes accelerator specific safety requirements and approval authorities which, when supplemented by other applicable safety and health requirements, promote safe operations. Jefferson Lab conducts a hazard analysis to determine its accelerator-specific safety risks. The controls necessary to mitigate those risks are provided in the Jefferson Lab Final Safety Assessment Document (FSAD). These credited controls form the bounding conditions for the Accelerator Safety Envelope (ASE).
