Hanford nuclear waste tanks at risk of explosionSubmitted by ecard71 on Thu, 04/04/2013 - 23:44
"US residents near the Hanford Nuclear Reservation may be in grave danger: a nuclear safety board found that the underground tanks holding toxic, radioactive waste could explode at any minute, due to a dangerous buildup of hydrogen gas.
After Sen. Ron Wyden (D-Ore.) asked the Defense Nuclear Facilities Safety Board (DFNSB) about the risks posed by the nuclear site, board members relayed their concerns about the potential for hydrogen gas buildup within the walls of a tank – particularly those with double walls.
"All the double-shell tanks contain waste that continuously generates some flammable gas," the board said in a letter received by Wyden on Monday. "This gas will eventually reach flammable conditions if adequate ventilation is not provided."
The safety board had previously issued a warning about their concerns, which have not yet been addressed. In September, the board sent a letter to the Department of Energy, claiming that there were no adequate safeguards to protect against the buildup of flammable gasses inside Hanford’s waste storage tanks. The letter, which outlines the concerns shared with Sen. Wyden on Monday, was declassified on Tuesday.
If the tanks were to explode, there would be flammable releases that would “have considerable radiological consequences, endanger personnel, contaminate portions of the Tank Farms, and seriously disrupt the waste cleanup mission,” the previously classified DFNSB report states.
Hanford’s double-shelled tanks contain some of the deadliest mixtures of nuclear and chemical waste left over from World War II and Cold War-era plutonium production. The Hanford Nuclear Reservation has been a serious cause of concern, since six of the facility’s tanks were found to be leaking about 1,000 gallons of nuclear waste each year. The Department of Energy discovered the leaks years ago, but has failed to address the problem."
