  1. Take 5 for Safety E. Lessard June 10, 2014

  2. CAS for Safety of Accelerator Facilities, DOE Order 420.2C • “the contractor must demonstrate to the satisfaction of the Field Element Manager that the following processes are in place: • A Contractor Assurance System (CAS) that maintains an internal assessment process • A Facility Configuration Management Program that is related to accelerator safety • Credited controls and appropriate administrative processes related to accelerator safety (e.g. training, procedures, etc.)”

  3. DOE O 420.2C CAS and Subject Areas at the Institutional Level • BNL Subject Area: A topic identified as being part of BNL's work processes; contains requirements and general guidance • About 7 Subject Areas address institutional CAS relevant to accelerator safety Order (DOE O 420.2C) • Conduct of Operations (training and procedures) • Facility Hazard Analysis (relationship between risk and controls) • Document Control (safety bases and authorizations) • Accelerator Safety (SAD, ASE, USI Process, Exemption Process) • Engineering Design (Credited Controls) • Configuration Management (Credited Controls) • Interlock Safety for High Risk Hazards (Credited Controls) • About 160 Subject Areas address CAS for control of standard industrial hazards covered in 10CFR851 and 10CFR835

  4. Credited Controls at the C-AD Accelerator Facility Level • Radiation Shielding • Access Controls Systems • Ventilation Systems • Stack Monitoring Systems • ODH Monitoring, Alarm and Shutoff Valve Systems • Soil Caps

  5. CAS Internal Assessment Process Related to DOE Order 420.2C • C-AD’s USI Process is a CAS • Procedure changes are reviewed for impact on Credited Controls • Design Review Questionnaire begins an assessment process for new projects or modifications to review impact on existing Credited Controls or help determine the need for additional Credited Controls • Work Planning and Control for Experiments and Operations begins a process to review jobs and experiments for impact on existing Credited Controls • Critique/Occurrence procedures begin a process to examine events to determine if they resulted from failures in Credited Controls or are outside the ASE or safety bases in the SAD • Document Control is a CAS and it is applied to drawings, safety analyses, calibration records, procedures and authorizations associated with tangible Credited Controls
