The Tricastin Nuclear Power
Nuclear power
Nuclear power is the use of sustained nuclear fission to generate heat and electricity. Nuclear power plants provide about 6% of the world's energy and 13–14% of the world's electricity, with the U.S., France, and Japan together accounting for about 50% of nuclear generated electricity...

Incidents

In July 2008, 18,000 litres (4,755 Gallons) of Uranium solution containing natural uranium
Natural uranium
Natural uranium refers to refined uranium with the same isotopic ratio as found in nature. It contains 0.7 % uranium-235, 99.3 % uranium-238, and a trace of uranium-234 by weight. In terms of the amount of radioactivity, approximately 2.2 % comes from uranium-235, 48.6 % uranium-238, and 49.2 %...

 were accidentally released. Due to cleaning and repair work the containment system for a uranium solution holding tank was not functional when the tank filled. The inflow exceeded the tank's capacity and 30 cubic meters of Uranium solution leaked with 18 cubic metres spilled to the ground. Testing found elevated uranium levels in the nearby rivers Gaffière and Lauzon. The liquid that escaped to the ground contained about 75 kg of unenriched uranium which is toxic as a heavy metal while possessing only slight radioactivity. Estimates for the releases were initially higher, up to 360 kg of natural uranium, but lowered later.
Ground and surface water tests indicated that levels of radioactivity were 5% higher than the maximum rate allowed. In the near vicinity and above ground, the local watchdog group CRIIRAD has detected unusually high levels of radiation.
French authorities banned the use of water from the Gaffière and Lauzon for drinking and watering of crops. Swimming, water sports and fishing were also banned. This incident has been classified as Level 1 on the International Nuclear Event Scale

In July 2008, approximately 100 employees were exposed to radioactive particles that escaped from a pipe in a reactor that had been shut down. Additionally, a nuclear waste leak that apparently had remained undiscovered since 2005 spilled into a concrete protective shell in Romans-sur-Isere. Areva

, who owns the site, ensured that the leak had not caused harm to the environment, but the issue sparked discussion about an old French army terrain, where nuclear waste was deposited in shielded dumps.
