RICHLAND, Wash. – One of the Hanford Site’s most critical risk-reduction efforts continues at the Plutonium Finishing Plant’s (PFP) main processing facility.
Since April, workers with EM Richland Operations Office (RL) contractor CH2M HILL Plateau Remediation Company (CHPRC) have safely removed large sections of the main facility, including two stairwells, several sections of piping, and an associated concrete vault.
This time-lapse video highlights lower-risk demolition completed through mid-July.
Demolition resumed after crews finished removing debris that had been on the ground since December 2017, when work stopped after a spread of low levels of contamination. Since September 2018, crews with CHPRC have safely packaged and transferred nearly 7,000 tons of debris to Hanford’s onsite regulated landfill.
Demolition of the remaining lower-risk portions of the main processing facility is expected to be completed by the end of August and is being done under a revised demolition strategy and safety controls implemented last fall.
Photos from late June and early July show lower-risk demolition progress on the east end of the Plutonium Finishing Plant’s main processing facility. Demolition on the remaining lower-risk portions of the facility is expected to be completed by the end of August.
“PFP demolition continues to be a high priority, and I am encouraged by the safe and steady progress,” said Tom Teynor, RL project director. “The enhanced safety measures in place since lower-risk activities resumed nearly a year ago have proved effective in protecting workers, the environment, and the public.”
This animation shows the revised demolition approach and enhanced controls, reflecting worker input. Pauses are built into the schedule to review lessons learned and incorporate additional input before proceeding.
“The physical progress on this project is really exciting to see,” said Jason Casper, CHPRC vice president for the PFP closure project. “I’m proud of our team’s continued focus on safety over speed.”
