HUKARI prepared a Safety Assessment Document (SAD) and Accelerator Safety Envelope (ASE) per DOE O 420.2B for demolishing Building 51 and the Bevatron accelerator at Lawrence Berkeley National Laboratory (LBNL). Hukari’s scope included:

• Review of existing characterization reports and used them to the extent possible in completing the SAD and ASE and supporting document deliverables

• Review of demolition contractor plans to evaluate techniques and associated hazards

• Assessment the state of the current facility, and the proposed end state
  Conducting site walk-downs, gathered documents and information, reviewed safety management programs

• Completion of accident consequence analyses of the facility

• Development of draft SAD and ASE documents, incorporated LBNL comments, and reviewed existing LBNL documents to ensure consistency with SAD and ASE

• Development of an Unreviewed Safety Issue (USI) procedure

• Meeting the accelerated schedule (3 weeks) for preparing the SAD and ASE which were subsequently approved by DOE.

This effort was the first SAD and ASE developed under DOE O 420.2B for decommissioning and demolishing an accelerator and is being used by DOE as an example of how to write them.
