According to recent statistics of the International Atomic Energy Agency (IAEA), there are more than 420 nuclear power reactors in operation worldwide. This includes 52 reactors in Japan (as of December 1998), where more than one third of the total electricity has been generated by nuclear power in 1998. It is estimated that 45% of total production will be nuclear- generated by the year 2010 (Figure 1-1). In November 1999, the Japan Nuclear Cycle Development Institute (JNC) submitted a series of technical reports to the Atomic Energy Commission of Japan (AEC). The overall intention of these reports, which together make up the Second Progress Report (H12) on Research and Development for the Geological Disposal of High-level Radioactive Waste (HLW), was to demonstrate the safety of geological disposal of HLW. Technical confidence in the reports is founded based mainly on the integrated results of generic research and development to date, in particular since PNC's (predecessor of JNC) Fir
