I think this is an urban legend. One of the things we H.E. physics geeks used to do in college was sit around the Union building designing really high yield, or really dirty, or really clean, or really small fission devices, and then critique each other's designs. At the time, SDI seemed to be very realizable (an EMP powered X-ray laser, using a tin wire in a lead rod was the design of one of the people in the group; needless to say, it was a one-time-use-only design). This was back before the bottom fell out of the weapons design market, and most of us ended up becoming professional computer scientists, instead. I still think SDI could be made to work... It hasn't been a design problem for a very long time; it's a materials availability problem, which is one of the main reasons nuclear materials are so highly regulated in the U.S. -- surprising, actually, given the number of fast breeder reactors in Japan and France.
