RICHLAND, Wash.– In this video, recorded May 20, Hanford Site workers place a protective cover over Tunnel 1 at the Plutonium Uranium Extraction Facility (PUREX), where a portion of the tunnel roof was discovered collapsed May 9. For reinforcement, crews strung cables across the cover, which is providing additional protection to workers and the environment while EM’s Richland Operations Office and contractor CH2M HILL Plateau Remediation Company develop and implement further risk mitigation measures.
