I think it's 100% U235, otherwise it would read just "uranium" and would represent the energy density of a mix of U235 and U238. This comic is drawn by Randall Munroe, a former NASA guy. He tends to get the science right. Wikipedia has the energy density of U235 at 83,140,000 MJ/KJ, so the comic was apparently being conservative. Most US Powerplants (Pressurized Water Reactors) run at low enrichment (say around 4%). Submarine reactors are really the only reactors that run with very high U-235 enrichment levels for a number of reasons. Spot price is typically quoted for natural uranium.

It's official. Dell has joined the dividend club. $0.08 dividend to be paid on October 22nd to shareholders as of October 1st. Give or take around a 3% yield currently. I still don't agree with starting a dividend policy now after they've resisted for so long as they stressed buybacks. Given the low share price I would much rather see buybacks now (as I think a lot of others would). Ah well, guess I can just reinvest the dividends myself after paying the tax / commission. Sigh... http://www.foxbusiness.com/technology/2012/09/06/dell-details-first-ever-dividend-payout/
