The Japan Nuclear Cycle Development Institute (JNC) was established on 1st October 1998 as the successor to the Power Reactor and Nuclear Fuel Development Corporation (PNC). In this report, PNC and JNC are referred to collectively as JNC. JNC is now preparing a second progress report (entitled H12) on research and development (R&D) for geological disposal of high-level radioactive waste (HLW) in Japan. H12 documents progress made since the publication of the first progress report (H3) in 1992 and will be presented to the Japanese Government for assessment by the year 2000. The purpose of the work was specified in a report published in April 1997 by the Advisory Committee on Nuclear Fuel Cycle Backend Policy of the Atomic Energy Commission (AEC). This report of AEC entitled "Guidelines on Research and Development Relating to Geological Disposal of High-Level Radioactive Waste in Japan" (AEC Guidelines) specified that the primary objective of H12 is to Present an outline of "the technica
