7/2/2011 Radioactive Waste Dumped in Open Pits Outside Los Alamos National Lab

Source: Washington's Blog
Date: 7/1/2011

To understand why a raging wildfire near the Los Alamos National Laboratory is a big deal, you must understand how wastes were disposed.
AP writes today:
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.
“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.”
But a report produced by the Alliance for Nuclear Accountability found:
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.”

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...
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.

7/2/2011 Transformer explodes at Tricastin nuclear power plant in Southern France

Date: 7/2/2011

I could not find any English reports on the fire so I piped some German and French articles through Google Translate. Following are the results.

Explosion in Atomkraftwerk Tricastin

Fire brought under control

Paris - In the southern French nuclear plant Tricastin it came to French media reports of an explosion. A fire had broken out, but this has been brought under control in the afternoon, it said on the website of the newspaper "Dauphine Libere." People were not injured. The explosion is said to have occurred in a transformer outside the nuclear zone. (APA)
From BFMTV.com:

A fire hit on Saturday afternoon, the transformer unit to stop the nuclear Tricastin in the Drôme. Large plumes of black smoke escaped but according to EDF, there will be consequences on the environment.

An explosion at the plant Tricastin

A transformer of the power plant Tricastin, Saint-Paul-Trois-Châteaux (Drôme), exploded Saturday afternoon. The fire was quickly brought under control and the damage appears to no effect on the operation of the site.
"The fire was quickly extinguished." The prefecture of the Drôme, interviewed by leJDD.fr , has sought to reassure about an explosion on Saturday at the site of the nuclear plant Tricastin, in the commune of Saint-Paul-Trois-Chateaux. According to EDF, also contacted, an electrical transformer outside the nuclear zone, exploded around 15:30, causing the temporary shutdown of the plant. Material was then caught fire, releasing a large black smoke, which was witnessed by many residents and road. "The wind has not pressed the smoke on the ground and no motorist was annoyed," assures the prefecture.
Internal services of EDF responded immediately, locking the access to the site. Firefighters responded just minutes later to control the fire, confined at 15:55. "No one was hurt and there was no damage to the environment," says the prefecture.
Tricastin plant is subject to careful monitoring of the nuclear safety authority (ASN). The latter, in a 2007 report, stated that "the site had yet to make progress on the management of training, development permits and fire response times in case of fire that remain too long." A year later, the release of carbon, in June and September, and a leak of uranium in July, had caused great concern. ASN also announced last Thursday, have imposed new security requirements concerning the EDF reactor No. 1 of the plant. Commissioned in 1980, it might work for another ten years if the EDF gives the standards. The explosion took place Saturday in the Unit 1 power plant, fueled by the reactor 1.

There have in the past been safety concerns and incidents at this particular nuclear power plant, as per Reuters and Wikipedia. A recent Bloomberg article dated 7/1/2011 details that EDF (Electricite de France SA) France's largest operator of nuclear power plants was ordered to improve the Tricastin nuclear power plant's defense against natural disasters (floods, earthquakes and fires):
...
EDF must reinforce the earthquake buffers at the Tricastin reactor as well as improve anti-flooding measures, according to a report released yesterday by the national atomic watchdog. Nobody from EDF could be reached for comment today.
