Nuclear weapons require the periodic replacement of tritium, a radioactive gas that decays at approximately 5.5 percent per year. Since 1989 the United States has no tritium supply facility, and, because of the decay of tritium, its inventory was expected to fall below the required reserve level is 2011.

This paper describes the decision ...
