John,
I may be mistaken, but I believe the picture of Diablo Canyon (one of my personal favorites) you use at the top of your site is copywrited by Jim Zimmerman, and he does not take kindly to people using his photo's without permission and due credit/payment. He generaly is content with a $50 payment for usage if his images.
I visited your site and think what you are doing is great. I might even add your RSS feed to our Nuclear News tab. (I can't see a reason why not to.)
