| Radioactive material has been found between two layers of a double-shelled storage tank at the Hanford Nuclear Reservation in Richland, Wash. (Shannon Dininny/Associated Press / August 21, 2012 |
Los Alamos Canyon runs past runs past the old Manhattan Project site in town and a 1940s era dump site where workers are near the end of a clean-up project of low-level radioactive waste. The World War II Manhattan Project developed the first atomic bomb, and workers from the era dumped hazardous and radioactive waste in trenches along six acres atop the mesa where the town sits.But a report produced by the Alliance for Nuclear Accountability found:
“The threat is pretty limited,” said Kevin Smith, the Department of Energy’s National Nuclear Security Administration site manager for Los Alamos, which over sees the lab. “Most of the materials have been dug up.”
Approximately 18 million cubic feet of radioactive and chemical solid wastes onsite were disposed of since 1943. “All of the radioactive waste and most of the chemical waste have been buried on the mesas of Pajarito Plateau where LANL is located. Radioactive liquid wastes were discharged to the canyons, initially with little treatment.”No wonder people have warned that the trees and soil in the areas surrounding the Los Alamos Laboratory may themselves now be radioactive. See this and this.
For many years, one method of disposal was “kick-and-roll”. The back of a truck was brought to the edge of a hole and barrels of waste were kicked. Wherever the barrels rolled tow as their final resting place.
No protection was put in place to ensure contaminants did not spread from the barrel. It is not clear that today’s practices are more protective.
An estimated 899,000 curies of low-level transuranic [i.e. radioactive elements heavier than uranium, such as plutonium] wastes were buried at Los Alamos. It is difficult to estimate exactly the quantity of radionuclides buried onsite due to the inaccurate record keeping and alterations in the definitions of low-elevel waste in the intervening years. Disposal continues today in unlined pits and shafts, a practice declared illegal by the New Mexico Attorney General’s office in 2011...
Tons of plutonium were processed at LANL in the early years of development and again in the 1980s. After the Savannah River Site, LANL contains the second largest volume of plutonium-238 in the US nuclear weapons complex: this type of plutonium has a 90-year half-life, a very high activity and is extremely hazardous...

The anti-nuclear watchdog group Concerned Citizens for Nuclear Safety, however, said the fire appeared to be about 3 1/2 miles from a dumpsite where as many as 30,000 55-gallon drums of plutonium-contaminated waste were stored in fabric tents above ground. The group said the drums were awaiting transport to a low-level radiation dump site in southern New Mexico.
Lab spokesman Steve Sandoval declined to confirm that there were any such drums currently on the property. He acknowledged that low-level waste is at times put in drums and regularly taken from the lab to the Waste Isolation Pilot Project site in Carlsbad. [2]

| 6/28/11 -- LOS ALAMOS FIRE MAP -- shows just how close the fire is to some serious waste! | |
I came across the most recent survey map of the wildfire in Los Alamos at the following site: [link to wildfiretoday.com] I thought it would be informative to overlay this map with a map showing the technical areas (TAs) and material disposition areas (MDAs) on the Los Alamos National Lab reservation. Check this out: [link to www.flickr.com] The fire is located within the hatched orange outline shown in the lower left-hand corner of the picture. I don't know the exact scale of this map but it is about 11 miles from Los Alamos to White Rock so that should give you some sense of distance. It appears that the fire, as of June 28th, is about a mile or so from TA-16 and TA-28. TA-16 is a tritium and high explosives processing facility according to: [link to www.lasg.org] TA-28 is an explosives storage area. As far as the MDAs go, the fire is closest to MDA-R, MDA-S, MDA-Z and MDA-AB. These contain various toxic metals, organics, high explosives and radioactive wastes mostly buried in pits. All of those 30,000 drums of low-level radioactive waste we have been hearing about are in MDA-G, which is further away from the fire at the moment. But, oddly, what we haven't heard much about is the storage site for transuranic waste which is in MDA-C. This one is a little scary. Here is the description from the LASG site: ------------------------------------------------ [link to www.lasg.org] Location: Technical Area (TA) -50 Period of use: Pits (6): June 1948 to December 1964 Shafts (107): 1958 to April 1974 Size: 11.8 acres Number and type of disposal units: Pits 1- 4: 610 by 40 feet Pit 5: 705 by 110 feet by about 18 feet Pit 6: 505 by 100 feet by about 23 feet Chemical pit: 180 by 25 feet by about 12 feet Vary between 1 to 2 feet in diameter, and 10 to 25 feet deep Specific wastes and quantities: Estimated Volume: 3,186,000 ft3 of TRU waste Pits contain, as of January 1973: 25 Curies (Ci) of uranium 26 Ci of plutonium-239 149 Ci of americium-241 Shafts contain: 49,136 Ci of tritium 40 Ci sodium-22 20 Ci of cobalt-60 31 Ci of strontium-90 5 Ci of uranium-233 50 Ci fission products 200 Ci of induced activity Also contains quantities of mercury, copper, cobalt, boron, beryllium, and silver. (2) Potential environmental impacts: Lies near Ten-Site Canyon New Mexico Environment Department's (NMED) Hazardous and Radioactive Material Bureau (HRMB) ranks this MDA as an area with a high probability of contaminant mobilization and a moderate to high potential of release to the groundwater. -------------------------------------------------- That is an insane amount of highly radioactive waste. And notice at the end there that it is ranked as HIGH probability of contaminant mobilization! Just a heads up for you guys. We really need to watch this thing! | |

Station Log:
6/27/11 Significant increase detected in gross beta gamma levels. System tests provide normal results. Radon levels are down currently and not correlative to increased beta / gamma.

The EPA announced in early May that it would cease testing air, rainwater, tap water and milk, as iodine 131 levels, the isotope with the shortest half-life, had fallen to normal atmospheric levels (EPA test results here). It has been reported at several websites that both NILU and the EPA were pressured to discontinue testing -- or at least to discontinue publication of the test results. The "pressure" has been variously attributed to the U.S. government, the Japanese government and the United Nations, although I have seen no hard evidence to substantiate any of those claims.[1]

...The media contact for Los Alamos National Lab when asked refused to confirm the statement by Concerned Citizens for Nuclear Safety:
The anti-nuclear watchdog group Concerned Citizens for Nuclear Safety, however, said the fire appeared to be about 3 1/2 miles from a dumpsite where as many as 30,000 55-gallon drums of plutonium-contaminated waste were stored in fabric tents above ground.

...The wildfire has already encroached upon the grounds of Los Alamos National Lab, having burned part of Tech Area 49, which in the 1960's was used to conduct underground testing of high explosives and radioactive materials.[1]
Lab spokesman Steve Sandoval declined to confirm that there were any such drums currently on the property. He acknowledged that low-level waste is at times put in drums and regularly taken from the lab to the Waste Isolation Pilot Project site in Carlsbad.[1]
