Senator Express Concern about Waste Storage Tanks at Hanford

摘要

While one of the newer double-walled nuclear waste storage tanks at a Washington state complex has leaked, six others have "significant construction flaws" that could lead to additional leaks, according to documents obtained by The Associated Press.One of those giant tanks was found to be leaking in 2012. But subsequent surveys of the other double-walled tanks performed for the U.S. Department of Energy by one of its Hanford contractors found at least six shared defects with the leaking tank that could lead to future leaks, the documents said. Thirteen additional tanks also might be compromised, according to the documents.
