The H17 project represents a status overview at a transition point between the generic phase of the Japanese HLW programme, which ended with the H12 project, and the truly site-specific phase which will commence when volunteers come forward allowing NUMO's staged implementation approach to be initiated. As such, the three technical reports document progress made during this period following the format of past progress reports. However, the present report puts this work in context by outlining a new approach which will applied to plan, structure and prioritise future R&D. Fundamentally, there will be a paradigm shift in the supporting R&D programme associated with completion of the movement to an active HLW implementation process at specific volunteer sites. Active site characterisation programmes will be complemented by development of repository concepts tailored to these sites within a structured, stepwise process. This will be associated also with the structural integration of JNC with JAERI to form Japan Atomic Energy Agency (JAEA) - an organisation which will be charged with the management of the fundamental knowledge base to support all stakeholders with interests in the HLW programme (implementer, regulator, academic and professional bodies, politicians and the general public). To facilitate such changes, a concept associated with a move to a formal KMS has been developed and is documented in this report. The KMS can be structured to interface with a user's RMS. In the absence of such an RMS, the important example of structuring to support development (or review) of a safety case has been illustrated. By mapping the knowledge produced by the H12 / H17 projects against the requirements for the next expected safety case in Japan (to support PIA selection), the extent to which all needs are covered can be analysed.

This report describes the results of the hydrochemical investigation of groundwater and hydrochemical modeling around MIU Construction Site in 2003. In this report, we considered about characteristics, evolutionary processes, pH, and redox condition of two types GW (Si-Na-Ca-SO4-HCO3 type and Na-Cl type). And it was cleared that, in Phase 2 (Construction phase of MIU), we must investigate carefully about degassing of dissolved gas in GW, because it may be strongly concernd about redox condition.

The final disposal of spent nuclear fuel or other high level long-lived radioactive waste is an enormous scientific, engineering and socio-political undertaking. To build a repository for radioactive waste we need the acceptance of the scientific community, the regulatory authorities, and the public for the disposal method to be applied and the site where the repository will be located. Furthermore, a successful implementation of a repository requires acceptance from a broad majority of people in all groups involved in the process. The issue of radioactive waste management has been with us for more than three decades and during this time considerable progress has been made. An international consensus has been reached that deep geological disposal is the preferred strategy for deailng with the high level or long-lived radioactive waste. There is also a general view that the scientific feasibility of geological has been demonstrated and that the technology is mature. The remaining task is industrial implementation and this will imply new challenges both technologically and, not least, socio-politically.

Tono Geoscience Center has been carrying out the Mizunami Underground Research Laboratory (MIU) Project, which is planned for broad scientific study of the deep geological environment as a basis of research and development for geological disposal of nuclear wastes. The Surface-based Investigation phase (Phase I) of the MIU project will be finished in the FY 2004, and URL Construction (Phase II)below about 50m depth will be started in the early of 2005.The paper is to be summarized concept and procedure of geoscientific research in the MIU project from FY 2003 to FY 2005.
