Officials say 6 barrels of waste in Texas tied to nuke dump leak

SANTA FE, N.M. (AP) — Scientists investigating a mysterious radiation leak at the federal government's underground nuclear waste dump have identified five other potentially explosive containers of waste from Los Alamos National Laboratory that are being stored at a site in West Texas, New Mexico Environment Secretary Ryan Flynn told a legislative panel Tuesday.

Flynn told lawmakers that scientists have been unable to replicate the chemical event believed to have a caused a drum to breach at the Waste Isolation Pilot Plant on Feb. 14, contaminating 22 workers. But they have tied the barrel to a waste stream from Los Alamos with an unusually high acid level, he said.

That waste was packed into a total of six drums, including the one at the Waste Isolation Pilot Plant in Carlsbad, New Mexico. The rest are among more than 100 that were shipped from Los Alamos to Waste Control Specialists in Andrews, Texas, after the leak indefinitely shuttered the New Mexico facility, which is the federal government's only permanent repository for waste from decades of building nuclear bombs.


Asked if the public should be worried, Flynn said: "Every member of the community should be concerned. ... But I don't think they should be worried. I don't think people should be panicked about another drum exploding because we required (the U.S. Department of Energy) to plan for that and have a system in place to protect the public."

Chuck McDonald, spokesman for Waste Control Specialists, said all the drums there have been specially packed and are under constant monitoring.

Extra precautions are being taken with barrels that have been identified as potentially more problematic, McDonald said. Los Alamos and Waste Control Specialists took a series of extra measures to secure the more than 100 drums left in limbo by the Waste Isolation Pilot Plant's closure because they were packed with cat litter to absorb moisture. A leading theory is that a switch by Los Alamos from inorganic to organic cat litter helped fuel the "heat event" that popped the lid off the 55-gallon barrel that leaked at the nuclear waste dump.

The Department of Energy has dozens of the world's finest scientists trying to identifying what type of reaction could have caused the leak, Flynn said after the hearing. But he estimated it would be months before a definitive cause is determined.

Until then, Flynn said, it is hard to speculate on what if any action can be taken to finish getting the last of thousands of barrels of decades-old waste off the Los Alamos campus in northern New Mexico. The lab had been under orders to have the waste shipped to the Waste Isolation Pilot Plant before wildfire season peaks. But given the uncertainty of what caused the radiation leak, transporting the waste now is seen as too risky.

Flynn said it also remains unclear how long the Waste Isolation Pilot Plant will be closed or how long it will take the plant to seal off the rooms where more than 350 other barrels of suspect waste from Los Alamos are currently stored.

"We just don't have any clear answers," he said.

"Of all the dispositions and habits which lead to political prosperity, religion and morality are indispensable supports. In vain would that man claim tribute to patriotism who should labor to subvert these great pillars of human happiness -- these firmest props of the duties of men and citizens. . . . reason and experience both forbid us to expect that national morality can prevail in exclusion of religious principles."
George Washington

Don't you guys cast your barrels?

SOP here for nuclear waste is to put the slop after separation of the useful isotopes into 20 gallon barrels, then cast the barrels in lead glass blocks. They go about a mile underground, each layer covered in and surrounded by a sand/graphite mix. Still toxic as hell, but less than bare waste.

There is a new thing catching on. Its called geomelting.Geomelting is the process by which dangerous, contaminated material (such as radioactive waste and heavy metals) is mixed with clean soil and melted down to create an extremely hard glass product. I believe that you are describing that method. You can see a form of it at the "Trinity" site in Los Alamos. The sand around the "Trinity" site and other sites has turned into glass
