Personally I don't think that nuclear is dead but I am in wait mode here to see how it all shakes out after this event. If you have to own 1 stock then HAT - Hathor would be the one for me.
Most of the Uranium stocks are at good entry points currently but I have decided to wait until the summer doldrums to see if some of these stock don't drift into extreme undervalued territory before I add any. I expect a pull back on the S&P.
Dennison is currently the largest producer of uranium in the US and there has been some controversy in there permits for expansion. They also have probably the richest deposit in Saskatchewan. This makes them a hybrid but they would still be my second choice because of the Megatons to Megawatts program ending and the US will need supply.
