<< The problem is that it is not in the middle of the desert, it is close to Las Vegas (I live in LV). The other huge problem is that we have very limited access to that location which means that much of it will be trucked right through town on its way there. We have over 1.5 million people living here not counting the hundreds of thousands of tourists that pass through. >>
4 inches of rain a year, with no measureable recharge to the water table, seems to qualify as a desert in most books. The "70 miles" must mean by air to the outskirts of town -- looks more like 90 miles to me. I've done the drive from Vegas through the Mohave, and the site sure seems like it's out in the middle of nowhere. If you can find an alternative place, on federal land, with no significant aquifer underneath, and no population centers within 70 miles, please recommend it.
In my personal opinion, the most sensible thing would be to build bunkered storage at the current sites, let the stuff decay 500 years, then reuse it. When I express this opinion to anyone in about 39 other states, they aren't too happy, and they come up with lots of pretty good reasons why they don't like the idea. In some cases, laws make the situation silly, and make it almost impossible to process waste into a safe form, until it has a place to go. Las Vegas should take a trip to Fernald, Ohio, where 4000 Ci of Radium, dating back to 1944, sits in leaking, concrete silos flanked by two streams, upstream from the town and in the middle of farm country. (Don't worry Las Vegans -- you successfully blocked that waste from going into the Nevada desert -- it's going into shallow, less safe storage in Utah, instead.)
Transportation is the only real issue, and it is mainly an issue of perception. Even if, in Shelley Berkeley's nuttiest scenario, a terrorist gets a direct hit with a missile and puts a grapefruit sized hole in the _outer_ shipping canister... so what? People act as if it will be Pandora's Box, with instant death for miles. In reality, even after a missile hit, the chance of a significant leak is zip, since the fuel rods are solid and still contained in other protective layers. Those canisters are incredibly tough, for good reasons.
But look at some of the other things that transport through Vegas every day -- like tanker trucks full of gasoline and propane. Suppose one of those blew up, just off The Strip? Do you recall that event at the Mediteranean resort some years back, whwre hundreds died after a tanker explosion? There have been two spectacular tanker accidents, one in Reno and one in Vegas, in recent years. With the one in Vegas, it is a miracle that more didn't incinerate.
<< I may be wrong here but I am sure there are other locations that are easier to access and not near such a huge city. My two cents. >>
