Thousands of gallons of radioactive waste are estimated to have leaked at a Manhattan Project-era nuclear storage tank in Washington State over the weekend, triggering an alarm and causing one former worker to label it as “catastrophic."
‘Catastrophic’: Up to 3,500 gallons of nuclear waste leak at Washington State storage site

The expanded leak was first detected after an alarm went off at the Hanford Nuclear Reservation on Sunday, and on Monday workers were preparing to pump the waste out of the troubled area, AP reported. They were also trying to determine why the leak became worse.
It’s unclear exactly how much waste spilled out, but estimates place the amount at somewhere between 3,000 and 3,500 gallons, according to the Tri-City Herald.
"There is no indication of waste leaking into the environment or risk to the public at this time,” the Washington Department of Ecology said in a statement.
The problem occurred at the double-wall storage tank AY-102, which has actually been leaking since 2011. At the time, the leak was extremely small, and the waste would dry up almost right after spilling out between the inner and outer walls, leaving a salt-like substance behind.
In March, the US Department of Energy began pumping what was left in the storage tank, which originally held some 800,000 gallons of waste. However, during this process – and after the alarms at Hanford went off – workers discovered that the leaked waste between the storage walls had reached a depth of 8.4 inches.
Pumping work on the tank has been halted as officials reevaluate the situation and figure out how to get to the leaked radioactive waste. It’s possible that the leak was made worse when the pumping began, but that has not been confirmed.
While the Department of Energy called the leak “anticipated” and the state Ecology Department said there was no danger to the public, the former Hanford worker who first discovered the leak had a different analysis.
“This is catastrophic,” Mike Geffre told King5 News. “This is probably the biggest event to ever happen in tank farm history. The double shell tanks were supposed to be the saviors of all saviors (to hold waste safely from people and the environment).”
After Geffre first discovered the leak, the government contractor managing the tanks, Washington River Protection Solutions, did not acknowledge the problem until 2012. The state has been pushing the federal government to remove the remaining waste since then, but work didn’t start on the project until last month.
According to the state Ecology Department, there are roughly 20,000 gallons of waste left inside the AY-102 tank.
Fortunately, there has been no indication that waste has made its way into a leak detection pit outside of the tank itself, the Seattle Times reported.
The Hanford Nuclear Reservation was originally constructed in 1943 as part of the Manhattan Project. After decades of producing plutonium for weapons, including the atomic bomb that was dropped on Nagasaki, Japan, millions of gallons of radioactive waste was generated by the time production stopped at the end of the Cold War. It is expected to cost billions of dollars to clean up the site over the course of decades.
‘Construction flaws’ in six Hanford nuclear waste tanks, 13 more may be compromised – report (Video)

Back dated March 1, 2014 - After one of the 28 huge underground double shelled tanks was found to be leaking in 2012, subsequent surveys performed for the US Department of Energy by one of its Hanford contractors found that at least six of the other tanks shared the same defects, according to the documents. A further 13 tanks may also be compromised, the inspectors found.
“It is time for the Department (of Energy) to stop hiding the ball and pretending that the situation at Hanford is being effectively managed," Senator Ron Wyden, D-Ore, who until recently was chairman of the Senate Energy and Natural Resources Committee, wrote Friday in a letter to Energy Secretary Ernest Moniz.
According to him, the six double-walled tanks which have construction flaws similar to those at the leaking tank contain about 5 million gallons of radioactive wastes.
Wyden also criticized the Department of Energy for not mentioning the flaw in the double walled tanks in a September framework plan for a cleanup in Hanford.
Hanford is located on the Columbia River in Washington State near the border with Oregon and contains 53 million gallons of high-level nuclear waste from the production of plutonium for the US nuclear weapons program. It was built during World War Two as part of the Manhattan Project to build the nuclear bomb. There are some 177 underground storage tanks on the site, many of which date back to World War Two. These are single skinned and many have already leaked. The 28 double walled tanks were built as replacement between the 1960’s and 1980’s.
