A 40-year-old plant at Los Alamos National Laboratory that treats liquid radioactive waste had another leak last month as some members of Congress balk at the rising costs of the plant's replacement.
The leak happened when a plastic connector cracked, spilling 500 gallons of contaminated water onto the floor inside one of the plant's buildings, according to a report from federal nuclear safety officials. The water flowed into a sump inside the building, and none of it escaped, according to the report.
The incident highlights the increasingly fragile nature of the aging plant. In a report to Congress earlier this year, the National Nuclear Security Administration said portions of the plant's waste treatment systems "are over 40 years old and their reliability is significantly diminishing."
But a key House committee this week eliminated funding for major upgrades, complaining about "significant cost overruns" for the project.
The June incident is the second time in the last year that a similar plastic part cracked and caused a leak, according to a report from the Defense Nuclear Facilities Safety Board, a federal body that provides independent oversight at Los Alamos and other nuclear weapon sites.
The Radioactive Liquid Waste Treatment Facility, located in the lab's Technical Area 50, came online in 1963.
The plant, connected by a network of piping to 63 buildings at Los Alamos, treats water contaminated with radioactive materials as a result of work on nuclear weapons and other projects at Los Alamos.
Los Alamos spokesman Kevin Roark acknowledged that the plant "does not comply with current codes and standards," including seismic, building and electrical codes.
The Safety Board has argued that problems at the waste treatment plant threaten the lab's ability to carry out work with radioactive plutonium to maintain U.S. nuclear weapons, because continued breakdowns would leave no way to deal with the radioactive waste the work creates.
Roark said the spill was cleaned up within days and did not interrupt operations at the plant.
In 2006, the National Nuclear Security Administration estimated the cost for waste management upgrades at $80 million to $100 million, but a budget report sent to Congress this year said it was likely to rise. |
