This report provides a summary of the results of studies on design and engineering technology for a deep geological repository for vitrified high-level radioactive waste (HLW) that have been conducted by the Japan Nuclear Cycle Development Institute (JNC). The Japanese multibarrier system is illustrated in Figure 1. The purpose of this H12 Supporting Report 2 is to address the objectives and issues on repository design and engineering that are described in a report published in 1997 by the Advisory Committee on Nuclear Fuel Cycle Backend Policy of the Atomic Energy Commission of Japan, entitled "Guidelines on Research and Development Relating to the Geological Disposal of High-Level Radioactive Waste in Japan" (the "AEC Guidelines"). For H12, the specific objectives are: to propose design requirements for a safe, reliable engineered barrier system (EBS) and disposal facility and, to show that the EBS and disposal facility can be reasonably constructed using currently available engine
