Last week , a leak in a storage storage tank at the country ’s largest radioactive dumpsiteexpanded substantially , sparking concernsthat other tanks are on the verge of failing , too . This fear may have already been realise . Rumorsare flyingthat a moment of Hanford ’s 28 double - shell radioactive wastefulness tanks is exhibiting former sign of failure .

King-5 News , which broke the story of the expound wasteland leak at Hanford site ’s AY-102 storage tank , isnow report evidenceof a second tank rift , citing anonymous sources familiar with the position . The tank car in question , AY-101 , is the same age and has the same design as AY-102 , which began leaking in 2011 . Both armoured combat vehicle , along with ten others at the Hanford facility , share a building flaw identify by the Department of Energyseveral year backas a potential risk factor for loser .
Hanford is a legacy site that produced plutonium for the human beings ’s first atomic bomb , and for almost 60,000 more nukes during the Cold War . Its last nuclear reactor was switched off in 1987 , and a year later , it was taken over by the DOE , the Washington State Department of Ecology , and the EPA for long - term environmental remediation . Due to the internet site ’s maturate substructure , that remedy process has been slow and dangerous .
Today , 53 million gallons of toxic sludge from the dawn of the atomic age still sit down in decrepit tanks at Hanford , wait for the government activity to build a remediation plant . In the early 2000s , grounds of widespread leaking prompted the DOE to remove the bulk of the waste from 148 undivided shell armored combat vehicle built in the ‘ 40 and ‘ 50 to 28 large , twice - shell tanks build in the 1970s .

The hope was that the doubly - shell tanks would prove more rich , but in 2011 , tank AY-102 bound a leak . Last week , as the terminal drop of radioactive permissive waste were being transferred from the busted tank into others , facility workers notice that the passing water had expanded considerably . The solvent : an accumulation of eight inches of radioactive waste between the inner and out hull . Both the nation ’s Department of Ecology and the DOE told Gizmodo that this was an anticipated resultant of draining the armoured combat vehicle .
But now , King-5 News reports that another double - shelled armoured combat vehicle has recently exhibited some life-threatening sign :
germ evidence KING 5 that alarm go off last week to alert staff of the front of “ hot ” ( radioactive ) particles immobilise in filter of the tank ’s uninterrupted air admonisher ( CAM ) .
The sources say this is the first time readings of this sort have been detected in AY-101 , lead people very conversant with the storage tank to believe the tank is beginning to fail .
The environmental watchdog chemical group Hanford Challenge issued a insistence release today take that is own sources within the facility have confirmed elevated radiation therapy levels outside of AY-101 ’s inside shell ; something that should n’t occur if the tank is air-tight .
“ agree to people who work there , this is a very good indicator of failure , ” Tom Carpenter , the executive director of Hanford Challenge and former director of the Nuclear Oversight Campaign for the Government Accountability Office told Gizmodo . “ Now , it may be a small leak , but it does n’t count . If the tank fails , they have to straightaway attract together a plan to empty that tank . ”
And that would be a bighearted problem for Hanford , which does n’t have enough room in its 26 remaining tanks to accommodate the spare waste . The facility would need to install new tanks , a process that could take several years . Alternatively , it would need to vastly accelerate plan for a long - term remediation deftness , currently scheduled to descend online in 2036 .
Gizmodo has reached out to the DOE and the state ’s Department of Ecology for comment and will update if we hear back .
Update 4:30 post-mortem examination : DOE tank managing director Tom Fletcher told the AP that visual inspections of the tank have found no evidence of a leak , but that air samples show rarefied level of radiation between the tank ’s intimate and out hull . DOE officials are presently see into the matter .
Update 4/27 : A DOE interpreter has sent Gizmodo the next statement :
During quotidian filter inspections , higher than normal reading for taint were found on filter newspaper installed on a continuous atmosphere monitor for Hanford ’s two-fold - shell tank car AY-101 doughnut . While these reading were higher than normal , they were well below the alarm level .
