Hanford has 56 million gallons of radioactive waste in those 177 underground tanks at this remote decommissioned nuclear production site near the Columbia River in Benton County.
Those leak-prone tanks are arguably the most radiologically contaminated place in the Western Hemisphere.
At least 1 million gallons of radioactive liquids have leaked into the ground, seeping into the aquifer 200 feet below and then into the Columbia River, roughly seven miles away. Since the mid-1990s, Hanford's plans involve mixing the waste in the tanks with benign melted glass and then storing it in glass logs.
Today, the project's budget is at least $17 billion, and the first glassification plant for low-activity waste is scheduled to start up in late 2023. So far, the federal government has spent $11 billion on the glassification project, according to the Government Accountability Office, the investigative agency of Congress.
That one plant, however, will only handle 40% to 50% of the low-activity wastes, depending on who is doing the estimating. A second low-activity waste plant or a stil-to-be-determined new approach is needed to the remaining wastes.is What will happen to the rest of the waste is still up for debate.
All of the single-shell tanks and the majority of the double-shell tanks are way past their design lives
Cleaning up nuclear waste at Hanford: Secrecy, delays and budget debates
A plan to turn radioactive waste into glass logs has raised a lot of questions, many of which don't appear to have public answers. CrossCut, by John Stang, August 16, 2021 Stephen Wiesman has worked for about three decades on the Hanford Nuclear Reservation's project to convert the radioactive waste in its huge underground tanks into safer glass logs.
Although he's retired now and involved in an advisory capacity, he understands the project — and its ongoing challenges — better than almost anyone.
Wiesman sees this task with a mix of cautious optimism, frustration, sympathy for the people dealing with its complexities, and a deep belief that the tank wastes must be dealt with. "There isn't an emotion that I haven't felt," he said.
The project faces a cluster of challenges: financial, technical and political. And the secrecy around the plans to solve these issues makes it difficult for anyone to gauge whether the most polluted spot in the nation will ever become a benign stain on the landscape of eastern Washington.
