"A second tunnel storing radioactive waste at the Hanford nuclear reservation has structural problems and is at risk of failing, according to a U.S. Energy Department investigation released Friday.
This tunnel is more than four times longer than the smaller Hanford tunnel that suffered a partial roof collapse May 9, triggering an order for more than 4,800 employees to stay indoors.
Officials say the May 9 event did not trigger any radioactive releases. But it did escalate safety concerns about the storage of high-hazard materials left from the legacy of Hanford’s plutonium production."
