Leak worsens in massive Hanford tank holding nuclear waste

A leak in a massive nuclear waste storage tank at the Hanford Site has expanded significantly, KING 5 learned this weekend.

After leak detector alarms sounded early Sunday morning, crews at Hanford lowered a camera into the two-foot-wide space between the tank's inner and outer walls. They discovered 8.4 inches of radioactive and chemically toxic waste has seeped into the annulus.

The U.S. Department of Energy released a statement Monday calling the leak an "anticipated" outcome of an ongoing effort to empty the tank in question. The Washington state Department of Ecology said, "There is no indication of waste leaking into the environment or risk to the public at this time."

But one former tank farm worker said the leak should be considered a major problem.
