The tank farms at the Hanford Nuclear Reservation in southeast Washington have the all-clear for work to resume after a high-radiation incident briefly shut down much of the site last month.
In late August, Hanford workers responded to an emergency of a high radiation reading near a tank known as C-101. In a new letter to Hanford workers, tank-farm manager Kevin Smith says it turns out there was no leak. He says “pre-existing contamination” on some concrete near the tank “could have been exposed when insulating blankets shifted.”
There is a four-inch square of contamination where elevated beta radiation levels were detected, he says. Smith says a Hanford contractor is preparing to re-start pumping activities. And some pre-pumping work will begin this week. Washington State Ecology officials say they are encouraged that radioactive waste removals will start up again and that the delays were fairly brief.
