Talk of nuclear revival rekindles waste concerns

That’s what lurks 10 feet underground at this Normandy plant: More than 7,000 cylindrical steel canisters, each about the height of a parking meter, stacked and sealed upright in holes beneath the slick floor. Some contain compacted radioactive metal, the others hold spent fuel that has been vitrified into glass.

Among other ideas once floated for disposing of nuclear waste have been shooting it into space (deemed too risky because of the volatile rocket fuel) or injecting it in the ocean floor (stalled because testing its feasibility is too costly), or shipping all the world’s waste to a collective nuclear dump.

The last idea proved too diplomatically delicate. But Greenpeace and Norwegian environmental group Bellona say European nations have for years been illegally shipping radioactive waste to Russia and leaving it there.

Current research in industry leader France — which relies on nuclear energy for more than 70 percent of its electricity, more than any other country — is focusing on new chemical processes that would shrink nuclear waste and cool it faster.

It will be at least 2040, though, before these might be put to use, scientists estimate. Schneider says scientists are “creating work for themselves” by researching methods that may never be commercially feasible or do much to solve the long-term waste quandary.

The World Nuclear Association, an industry group, disagrees, citing increasing interest in waste research by governments. The managers at the Normandy plant say long-held taboos about the industry are fading.

“We have the best scientific solution for treating waste,” deputy director Eric Blanc said, referring to the plant’s vitrification process and network of cooling pools. “Others are coming all the time to study it.”

Visitors to the plant must wear special uniforms and trek through a maze of security and radioactivity checkpoints.

Webcams gone after 9/11
The plant used to have Webcams and “open house” days for people from nearby communities, but both practices were stopped after 9/11. Now the Defense Ministry regularly monitors the plant, and vets all visitors.

Meanwhile, new reactor clients are lining up.

China signed a staggering $11.7 billion deal last month for two nuclear reactors from Areva. Areva later said the deal included a feasibility study for a waste treatment and recycling facility in China that would cost another $22 billion.

Areva already makes $2.2 billion in revenues a year on treating and recycling waste. The plant at Beaumont-Hague takes in 22,000 tons of spent nuclear fuel a year, from France, Japan, Germany, Switzerland, Belgium, the Netherlands, Italy and Australia. The foreign fuel by law must be returned to its owners once it has been reprocessed into a more stable form that — through lack of alternatives — is buried or held in storage.

The French fuel stays in Normandy indefinitely, while bulkier, lower-level nuclear waste is piling up in dumps worldwide.

Nuclear scientists’ dream is a wasteless reactor, and some sketches for the next crop of reactors, the Generation IV, include those that recycle 100 percent of their refuse.

Both nuclear fans and foes agree, however, that it will take a few more human generations for that dream to come true.
