I think I need some coffee. Check out this resource for your environmental classroom at http://pubs.acs.org/journals/esthag/index.html
It may be a little over high level for most of my kids, but if you teach AP Environmental, add it to your list of required reading if you have not already done so.

Reshaping nuclear fuel
Doughnut-shaped fuel can cut nuclear energy's environmental impact.
light-water nuclear reactors
When used as fuel for light-water nuclear reactors, the hollow 14-mm cylinders shown here can increase efficiency by 50%.
By reconfiguring nuclear-fuel pellets into "dough nuts", scientists from the Massachusetts Institute of Technology (MIT) have found a way to boost the amount of energy that nuclear reactors produce by 50%. The new design also helps diminish the chance of meltdown by slashing the temperature at which reactors must be operated, and it renders the spent fuel more proliferation-resistant.
