SRS waste tank project takes step forward

  • Follow Metro

A $1.4 million Recovery Act-funded project to prepare one of Savannah River Site's radioactive waste tanks for permanent closure was completed this month.

The modifications, which included repairing a ventilation system and replacing a pump on the 750,000-gallon tank, are part of a plan to close 22 of the site's remaining 49 tanks within eight years.

Originally, there were 51 underground tanks at the site's H and F areas. Two were closed in the 1990s, and the remaining tanks still contain 36 million gallons of decaying waste left behind by decades of Cold War nuclear weapons production.

John Lindsay, a spokesman for liquid waste contractor Savannah River Remediation, said six tanks are in some phase of closure activity.

"Right now we're working on 5 and 6, and those will be followed by 18 and 19 and then we will move to 4 and 12," he said.

The company, with about 1,765 employees, took over management of the liquid waste cleanup program in July.

The waste in the aging tanks includes thick liquids, sludge with a consistency similar to peanut butter and a caustic material that turns to salt.

Twelve of the tanks are leaking, but the leaking areas are contained to prevent material from entering the environment.

Disposal programs include emptying the tanks, processing the waste and then filling in the aging, carbon-steel vats with a specialized grout and leaving the tanks buried forever.

Each tank is 86 feet across and 44 feet deep, and all are buried 10 to 12 feet below ground level.

The huge increase in the rate

The huge increase in the rate of tank closure sounds good but if they can't pull it off the new company, Savannah River Remediation, should be penalized severely.

The Dollars never end. I

The Dollars never end. I worked for 28 years on projects to clean up SRS waste tanks. Every time we get a new Pres. on Sec. Of Energy the plan changes and funding is cut and work stopped. Other than the Defense Waste Processing facility the rest of the place is one be experiment gone bad. If the DOE would stick to the plan and let the employees that are do there job, those tanks would have been empted yeras ago.I stand to be corrected!
