The purpose of EHS Procedure 703.4, Unreviewed Safety Issue Process, is to define the institutional-level Unreviewed Safety Issue (USI) Process for Lawrence Berkeley National Laboratory (LBNL), ensuring compliance with U.S. Department of Energy (DOE) Order 420.2D, Safety of Accelerators (hereafter “Accelerator Safety Order,” or “ASO”).
The procedure applies to accelerators at LBNL that operate above 10 MeV and works in conjunction with an accelerator facility’s current Safety Assessment Document (SAD), DOE-approved Accelerator Safety Envelope (ASE), and facility-specific implementing procedures. Accelerators that operate at 10 MeV or below, or have a DOE-approved exemption from ASO’s Contractor Requirements Document Section 2(b).3, are not subject to the USI Process but may choose to apply the process nonetheless.
