Explosion at French nuclear plant of Marcoule
One person has been killed and four injured, one seriously, by an explosion at the southern French nuclear plant of Marcoule.
There were no radioactive leaks after the blast, caused by a fire near a furnace in a radioactive waste storage site, a French nuclear official said.
A security perimeter has been set up because of the risk of leakage.
The plant produces MOX fuel, which recycles plutonium from nuclear weapons, but does not include reactors.
It is a major site involved with the decommissioning of nuclear facilities.
The Centraco treatment centre belongs to a subsidiary of national electricity provider EDF.
The explosion hit the plant at 1145 local time (0945 GMT).
"For the time being nothing has made it outside," said a spokesman for France's Atomic Energy Commission (CEA).
Marcoule, one of France's oldest nuclear plants, is located in the Gard department in Languedoc-Roussillon region, near France's Mediterranean coast.
Nuclear energy provides more than 70% of France's energy needs.
All the country's 58 nuclear reactors have been put through stress tests in recent months, following the disaster at Japan's Fukushima nuclear plant which was hit by an earthquake and tsunami.
EDF's share prices fell by more than 6% as news of the blast emerged.
An explosion has occurred at a nuclear site in southern France, according to the country's nuclear safety watchdog.
The facility at Marcoule is a nuclear waste management site that does not include any reactors. The explosion took place near a furnace, an spokesperson for ASN, the watchdog, told Reuters.
Officials in the Gard region confirmed Monday's explosion but also said they could not give any more information.
The Marcoule site is located in Langedoc Roussillon, in southern France, near the Mediterranean coast.
