Tier 2 safety Basis Document for the B151 Complex (B151, B152, and B154)
This Safety Basis Document (SBD) has been prepared for the B151 Complex at Site 200 to meet the current contractual requirements at Lawrence Livermore National Laboratory (LLNL). B151 Complex consists of three separate complex and distinct buildings: B151, B152, and B154, represented within this document as facility segments. Based upon its chemical and radiological inventories, Segment B151 is classified as a Low Hazard facility segment. All other hazards associated with Segment B151 operations have been determined to be LSI. Based upon their inventories, Segment B152 and Segment B154 are each classified as LSI facility segments. However, for operational flexibility involving radiological materials, CMS chooses to classify each of these as Low Hazard facility segments. Changes in operations, maximum inventories, materials, or release potential that could result in larger consequences, or that could negatively impact the safety of the facility, will necessitate a re-evaluation of these facility classifications. This SBD is governed by the LLNL Non-Nuclear Work Smart Standards (WSSs) requirements including the ES&H Manual, Document 3.1, Non-Nuclear Safety Basis Program [LLNL, 2004a] and the DOE Explosives Safety Manual (ESM) [LLNL, 2004b]. This SBD demonstrates that the three segments of B151 Complex can be operated as Low Hazard facility segments without undue risks to co-located workers, the public, or the environment. This SBD: (1) Provides a systematic identification of the safety and health hazards associated with operations in the B151 Complex, (2) Compares facility inventories of explosives, biological materials, chemicals, radioisotopes with LLNL threshold values for each facility hazard classification criteria, (3) Examines standard and non-standard industrial hazards, (4) Examines the hazards of greatest significance, (5) Qualitatively discusses the programs that evaluate and control these hazards to ensure the protection of co-located workers, the public, and the environment, and (6) Addresses the required administrative controls and design features that would eliminate, control, and/or mitigate the identified hazards.
