Why Do We Need The ASO? E. Lessard Collider-Accelerator Department (C-AD) Brookhaven National Laboratory DOE Accelerator Safety Workshop to

ASO-ASE Operations Limits at C-AD  Radiation  Personnel and public exposure limits  Radiation detector interlock testing  Access interlock system testing  Inspection of activated soil caps  Environmental release limits  Oxygen Deficiency  ODH sensor and alarm testing  Fire  Fire detection system configuration  Fire alarm testing  Flammable gas detection system testing 2

ASO-Guide Operations Envelope at C-AD  Two operators at controls  Trained and qualified operators  All work must be planned  Environmental compliance  Modifications reviewed for safety  Controls for industrial hazards 3

4 What Value Does Order Bring To Contractors? To DOE?  Summary of bad events that caused shutdown at accelerators:  Fire  Electrical failure and injury to worker  Unplanned radiation levels  Electrical / mechanical failure  The ASO establishes appropriate operational readiness and change control to avoid these bad events  The ASO demonstrates contractor commitment to adhere to ASE Limits and Operations Envelope  The ASO improves line accountability  The ASO increases worker involvement in safety

Without The Order, What Regulatory Framework Would Accelerators Operate Under?  NRC would regulate non-incidental radioactive materials  Intentionally produced materials such as medical radionuclides  No authority to regulate possession or operation of accelerators  OSHA references DOE ASO Guide in SHIB  OSHA would regulate accelerator operations if not done by DOE  OSHA would regulate incidental radioactivity if not done by DOE  ESH rules that apply to accelerators with or without the ASO  10 CFR 835, DOE Regulations for Radiation Workers  10 CFR 851, DOE Regulations for Worker Safety and Health - ASME for pressure and vacuum vessels - OSHA for lasers, ODH, LOTO, electrical safety, non-ionizing radiation, egress, confined spaces, fire protection …  10 CFR 40, EPA Regulations  Other DOE Orders?
