Leak in massive Hanford nuclear waste tank getting worse via King5.com

RICHLAND, Wash. — Workers have found more waste leaking between the walls of a nuclear storage tank on the Hanford Nuclear Reservation.

The waste was found in a new place between the walls of one of the 28 double shell tanks at the site. The US Dept. of Energy, which owns Hanford, says the waste is covering an area of 7 feet by 21 inches. The double shell tanks were built to be the most robust tanks at Hanford. They were constructed with the intent to be able to safely store the dangerous wastes until the technology to permanently dispose of the liquids is developed. A leak in a double shell tank is seen as one of the biggest setbacks to the cleanup program at Hanford in the last decade.

It’s been nearly two-and-a-half years since recently retired WRPS worker, Mike Geffre, found the first signs of the leak in October, 2011. To date, there is no solid plan on how to mitigate the leak or pump the contents of the tank to a safer holding vessel. Geffre says the company is stalling.

“Instead of being pro-active they become defensive. You need to handle everything as if it’s real. You may respond to a few false alarms but that’s the way it is. You cannot handle things, in the wait and see (mode). In the radiation world and the nuclear world that is extremely irresponsible,” said Geffre.

The Washington State Dept. of Ecology, which is a regulator at Hanford, has given the US Dept. of Energy until Friday, March 7, to submit a revised pumping plan for AY-102. The plan originally submitted by the USDOE in June, 2013 was highly criticized by the Dept. of Ecology. A top Ecology official wrote a scathing letter to federal officials in January. “We are deeply disappointed,” wrote the state’s Nuclear Waste Program director, Jane Hedges. “You appear to have no plan” and “we cannot support merely waiting for conditions to worsen before taking action.”

After the announcement of the newest leak identified in the tank, Dept. of Ecology Director Maia Bellon said this is further evidence that the contents of the tank must be emptied as soon as possible.

“We believe the law is clear. We are anxiously awaiting tomorrow’s new plan from the federal government to remove the waste. If it’s not acceptable, Ecology will consider the need for further action, including possible enforcement. Based on information provided by the U.S. Department of Energy to date, there is no indication that waste from AY-102 has reached the environment. The state fully expects the federal government to provide all details about this leak as their investigation continues,” wrote Bellon in a statement to KING 5.
