Hanford Nuclear Reservation

Workers are back on the job at the Hanford Nuclear Reservation’s waste treatment plant. Work stopped this week when radioactive soil was found under the nests of some swallows.

Swallows used some radioactive mud to make nests on exposed beamwork in Hanford’s waste treatment plant. That’s the $12 billion factory designed to bind-up radioactive sludge in glass logs. The nests were found during routine tests, but this is the first radioactive contamination of the new plant.

The people overseeing the cleanup of the Fukushima nuclear power plant disaster are learning some valuable lessons from the long-running cleanup at the Hanford Nuclear Reservation. A Japanese government delegation recently toured some of the southeast Washington site.

In Japan, workers in gloves and masks are grinding down sidewalks and roads, wiping down rooftops and bagging contaminated soil. Now, the problem is where to put all that radioactive waste from Fukushima.

Cleanup of a hazardous chemical called hexavalent chromium in the groundwater at the Hanford Nuclear Reservation in southeast Washington is going faster than expected.

Hexavalent chromium is the nasty stuff that made Erin Brockovich famous down in California. The chemical was used to inhibit rust in coolant water in Hanford’s reactors. But that water was dumped into the desert, and now the cancer-causer is making its way toward the Columbia River in large groundwater plumes.

RICHLAND, Wash. – It may take two to four years to even begin clearing radioactive waste from leaking tanks at the Hanford Nuclear Reservation. That’s according to Washington Governor Jay Inslee. He toured the southeast Washington nuclear site Wednesday.

RICHLAND, Wash. - Washington Gov. Jay Inslee says it may take two to four years to begin removing liquids from leaking tanks at the Hanford Nuclear Reservation. The Democratic governor made the comments Wednesday after a tour of the southeast Washington site.

The governor told reporters on the tour that there is no technology that can stop the leaks.

RICHLAND, Wash. – As many as 4,800 workers could be furloughed or laid off at the Hanford Nuclear Reservation in southeast Washington. It’s the result of the federal spending cuts known as the sequester. Hanford will need to cut $182 million in cleanup work according to a federal letter to Washington Governor Jay Inslee released Tuesday.

RICHLAND, Wash. – President Obama’s nominee for the next federal Energy Secretary is no stranger to the cleanup work at the Northwest’s Hanford Nuclear Reservation. Ernest Moniz was Energy undersecretary during the Clinton Administration and back in the late '90s he faced scrutiny about tank leaks at Hanford.

The problem -- and question then -- was whether about a million gallons of leaked radioactive tank waste had reached the groundwater and was headed toward the Columbia River. Or if it was staying put in a dry layer of soil, above the groundwater.

RICHLAND, Wash. – A new detail has emerged on the leaking tanks at the Hanford Nuclear Reservation. The federal Energy Department acknowledged last week that six single-shelled tanks are holding less radioactive waste than they used to. Monday the agency said those tanks are losing less than three gallons a day.

Worst case: Three gallons per day adds up to 1,095 gallons of radioactive waste per year. The Department of Energy says it doesn’t know yet how long these tanks might have been seeping waste.

RICHLAND, Wash. – A Hanford Nuclear Reservation watchdog says U.S. Energy officials have bigger problems than the waste that has possibly leaking from a tank in southeast Washington. The tank called T-111, is losing about 150 to 300 gallons of liquid waste a year.

Tom Carpenter heads the Seattle-based watchdog group Hanford Challenge. He says Friday’s news highlights the fact that there’s little space to move highly radioactive waste to.

RICHLAND, Wash. – A tank full of radioactive waste at the Hanford Nuclear Reservation in southeast Washington may be leaking. Friday the U.S. Department of Energy and its contractors say liquid levels in an underground radioactive waste tank are going down.

The single-hulled tank is called T-111. It’s located in central Hanford in a group of tanks called T-farm. The Department of Energy reports the rate of loss is about 150 to 300 gallons of liquid a year.

RICHLAND, Wash. - A bipartisan group of senior senators is drafting a bill to overhaul the U.S. nuclear-waste program. The group, which includes Oregon’s Democratic Senator Ron Wyden, is aiming to find a permanent home for the nation’s radioactive waste.

In childhood, our allegiances, our loves, are often black and white, simplistic. One of the difficult parts of becoming an adult is reconciling ourselves to the failings and flaws in what we have loved and admired. Sometimes the task involves recognizing our own complicity in those failings.

When Governor Chris Gregoire leaves office in January, she’ll take with her nearly a quarter-century’s worth of expertise on one of the most contaminated places on earth. Cleanup of the Hanford Nuclear Reservation has been one of her top priorities. Before Gregoire was governor, she worked on Hanford issues as the state’s attorney general and before that as ecology director.

Gregoire knows cleaning up Hanford is no easy task. She’s been involved longer than many of the top federal site managers. And despite all of the problems and complexities she’s still optimistic.

RICHLAND, Wash. – The federal government plans to release a major document early next week that could guide a couple of decades worth of cleanup at the Hanford Nuclear Reservation. This is important because it maps out decisions like where to bury the radioactive waste, and how much to leave in place.

The new document is huge -- 6,000 pages huge. And it’s taken about 10 years to draft.

Hanford Managers Mull Solutions For Leaky Tanks

Nov 15, 2012

RICHLAND, Wash. – Some of the decisions made over the last 40 years at the Hanford Nuclear Reservation are coming back to haunt the site’s current managers. A new report out this week examined why a double-hulled tank of radioactive waste recently sprung a leak in its inner shell. That has raised the possibility of having to pump out the waste from the tank.

The tank is called AY-102. And it’s about the size of a house. It’s buried in the sandy soil north of Richland.

RICHLAND, Wash. – Workers the Hanford Nuclear Reservation are readying pumping equipment at a slow-leaking radioactive waste tank in case the leak gets worse. A newly released report details why the tank became unstable.

Hanford officials say so far they’ve found no waste leaking into the environment from the tank called AY-102.

The new report says many of the tanks original welds from 40 years ago didn’t meet standards and had to be fixed before it was filled. Later, super-hot waste was added that was likely corrosive to the tank’s metal walls.

RICHLAND, Wash. – Energy Secretary Steven Chu is bolstering the scientific brain power at the Hanford Nuclear Reservation’s waste treatment plant. A memo released to employees Thursday says the aim is to solve nagging technical problems at the plant more quickly.

The massive factory at Hanford is supposed to treat 56 million gallons of radioactive waste. That goo is currently in leaking, aging underground tanks near the Columbia River.

RICHLAND, Wash. – Managers at the Hanford Nuclear Reservation have confirmed that a radioactive waste tank has a slow leak. That waste isn’t getting into the environment.

This house-sized vessel is known as AY-102. It’s made of steel and concrete and buried underground to shield workers from high levels of radiation. It’s full of hazardous radioactive sludge left over from plutonium production here.

It was designed to last for about 40 years, and it’s already had its 44th birthday. The tank is leaking into the space between its two hulls in two spots.
