50th Anniversary of U-233 Start of Molten Salt Reactor

Somehow I overlooked the 50th anniversary of the Oak Ridge National Lab's Molten Salt Reactor going critical using Uranium-233.  In retrospect, Glenn Seaborg (on the right in the above photo with Alvin Weinberg) wrote that killing this research was probably a mistake.  Read Kirk Sorensen's write-up on this milestone by clicking here.  One issued that should be noted is that the Dept. of Energy is currently working on disposing of the ORNL stockpile of U-233 in a radioactive disposal site Nevada National Security Site.  This is being done due to the cost of securing the U-233 stockpile.  Let us hope that the disposed U-233 can be retrieved some day, if needed.
