a group of MIT Scientists found that recycling is more expensive than the once-through process Note that this recommendation is qualified in the paper: "over the next half century". After that time, they imply that uranium may be scarce/expensive enough that we will need an alternate approach. They also estimate that the plants we build will have lifespans of 40 years and that we will need a new Yucca Mountain-size waste storage facility every 3-4 years. It's a little troubling that our nuclear solutions to the energy problem won't last out the century, while the sites that we create for them will be polluted for thousands of years.
