Well, there are some alternatives to rewinding the materials back to their original state (which was also radioactive).
- Grind it all to dust, bin sort each atom (like they do to get U235) to get materials of interest. - Toss it all into a pocket-sized black hole, which will let it all evaporate out as something more mundane (while likely spraying the area with hard radiation at infall). - Bombard it with thermal neutrons until it gets really hot (make it into something with a shorter half-life). - Grind it and bake it into big ceramic cakes, insert thermopiles, and generate electricity - Let it sit and hope our children are smarter than we have been in the last 50 or so years. - More?

Residents in Bollene in the Vaucluse, a tourist area, have been told not to drink water or eat fish from nearby rivers, after 74kg of liquid uranium were spilled on July 7 at the Tricastin nuclear plant.

I'm still for it, though. Actually thousands die each year due to coal mining, mostly in coal mines in China.

Dear jim:

Coal-fired plants go up in months, while nuclear reactors take years.

Yes, because it makes profit sooner, many fewer permits, its radioactive waste is allowed to blow downwind, and the anti-nuke crowd doesn't seem to care.

Nah, its the "birth certificates" for every component and triple+ redundancy that carry the cost.

Some. More would go to wind, solar, and power generation from waste too.

No need. Cite the coal fired plants for releasing radioactive materials and arsenic. That will shut them down.

Coal kills thousands of people, mostly miners.
Nuclear reactors only take so long because of the bureaucrat foot-dragging.
If you know where to shop, and if the Gov't weren't wallowing in paranoia, you could buy one off the shelf, and have it set up in DAYS.

Same can be said for mining and refining operations for any nuclear fuel. Not selling, just point out...

Love the change of name for the US market - LOL !

" The Union of Concerned Scientists has referred to the EPR as the only new reactor design under consideration in the United States that "...appears to have the potential to be significantly safer and more secure against attack than today's reactors." "

"In 2006, Business Week magazine stated, "...,the [US] industry is aiming to build new plants for $1,500 to $2,000 per kilowatt of capacity,...". However, they also added, "Trouble is, the cheapest plants built recently, all outside the U.S., have cost more than $2,000 per kilowatt."[11]
2007 estimates have considerable uncertainty in overnight cost, and vary widely from $2,950/kWe (overnight cost) to a Moody's Investors Service conservative estimate of between $5,000 and $6,000/kWe (final or "all-in" cost).[12]
However, commodity prices have shot up recently, and so all types of plants will be more expensive than previously calculated[13] In June, 2008, Moody's estimated that the cost of installing new nuclear capacity in the U.S. might possibly exceed $7,000/kWe in final cost.[14]" _____________
Makes every kind of Solar look good from a cost POV.

Dear qrus19:
...

What were the last seven years then?

His mantra is and has been he would seek consensus. If there were facilities to process the waste, rather than bury it, then he'd have a positive option and his advisors (whoever they'd be) would know about it. But no telling where this will go with him.
Burying it in non-solid form is not "the best we can do".

Plenty of room out here in Arridzona. Bring your own water though...

Sounds about right - very long payback before the investment starts earning you benefits. Solar cell generation is still only truly practical for "Off Grid" uses, repeater sites on remote mountain tops and people living waaaaaaay out in the hinterlands, where the power lines don't even think about going.
You can cover the roof of an industrial building with solar cells, or plant large expanses of them on a swath of open land outside town, but it's more of a Feel Good "Green" gesture than huge savings.

And once built, would stay essentially untouched for decades.

Just a note - the 'one visit per month from the fuel truck' sounds suspiciously like they don't want to carry too much fissile material in any one truckload at any one time. So they spread it out to keep the shipments small.
Last I heard they only have to shut down Nuke Plants for refueling every 18 months to three years, depending.
