Enforcement Letter issued to CH2M HILL Plateau Remediation Company related to Radiological Work Control Deficiencies at the Plutonium Finishing Plant and 105 K-East Reactor Facility at the Hanford Site

The Office of Hea1th, Safety and Security's Office of Enforcement and Oversight has evaluated the facts and circumstances of a series of radiological work deficiencies at the Plutonium Finishing Plant (PFP) and the 105 K-East Reactor Facility (105KE Reactor) by CH2M HILL Plateau Remediation Company (CHPRC).  The radiological work deficiencies at PFP are documented in the April 29, 2011, Department of Energy Richland Operations Office (DOE-RL) Surveillance Report S-11-SED-CHPRC-PFP-002, Planning and Execution of Radiological Work. S-11-SED-CHPRC-PFP-002 documented four examples where inadequate hazard analysis resulted in airborne radioactivity that exceeded the limits of the controlling radiological work permit.
