This blog often covers nuclear topics. For those who would like to learn more, the University of Pittsburgh is offering a free online course in Nuclear Science and Technology (Hat tip: Nuke Pro). The course starts on 3 March 2014 (there are future rounds as well) and runs for eight weeks in English and with subtitles. You can sign up here. All it will cost you is the textbook, which is here. It is also available at many different libraries, listed here (get the 1992 second edition or its 2008 reprint). And you might need to brush up on your basic physics and differential equations.
