     Japan's plutonium inventory practically doubled between 1993 and 1996 from almost 11 tonnes to over 20 tonnes. The largest increase stems from overseas reprocessing in particular at the French La Hague plant. Unfortunately, figures for 1996 are not yet available as detailed as for the other years. However, the evolution of the Japanese plutonium stock is a clear demonstration of the lack of adaptability in the planning departments of utilities and government.
