Energy Net on 28 Jun 10"Hanford workers have resumed digging up temporarily buried transuranic waste in central Hanford with improved technology that should take some of the surprises out of the work. Retrieval of the transuranic waste -- typically debris contaminated with plutonium -- was stopped in February by CH2M Hill Plateau Remediation Co. when it ran into problems. Since then the Department of Energy contractor has been working on improvements to its processes. In 1970 Congress ordered transuranic waste sent to a national repository. But until the Waste Isolation Pilot Plant in New Mexico opened, Hanford workers have been storing waste suspected of being transuranic, often by temporarily burying it. Much of the waste that Hanford workers have dug up so far to ship to New Mexico was buried in tidy rows and information about what's underground has been available. But within the last year CH2M Hill has been progressing to more difficult burial trenches, and that's contributed to problems."
