Radioactive waste canisters corroded

@thelocalgermany– 10 October 2014    Inspectors in northern Germany have found that a third of barrels containing radioactive waste at a decommissioned nuclear plant are damaged, the Schleswig-Holstein Environment Ministry said on Thursday.

Vattenfall, the energy company which manages the Brunsbüttel site in Schlewswig-Holstein, reported that 102 of the 335 barrels stored in the site’s six underground chambers were corroded, leaking or had loose lids.

Some of the containers are so deformed that they can no longer be moved, as they no longer fit into the robotic gripping arms installed at the site, the inspectors reported…….

So far, Vattenfall has only inspected four of the six chambers using remote cameras.

The chambers themselves are built from concrete and have walls over a metre thick to prevent radiation escaping into the surrounding environment.

The energy company has sent a proposal to the Schlewsig-Holstein Environment Ministry for making the storage facility more secure, including by installing dehumidifiers to slow corrosion, which has yet to be approved by government experts.

“The chambers [at Brunsbüttel] were supposed to be a temporary storage facility,” Vattenfall said in a statement on Thursday. “They weren’t designed to for long-term containment.”

It was originally planned to store the barrels at Brunsbüttel until they were moved to the ‘Konrad’ mine shaft site in Lower Saxony.  https://www.thelocal.de/20141010/one-third-of-barrels-leak-at-nuclear-waste-site-brunsbttel
