Locating a radioactive waste repository in the ring of fire
Locating a radioactive waste repository in the ring of fire
The scientific, technical, and sociopolitical challenges of finding a secure site for a geological repository for radioactive wastes have created a long and stony path for many countries. Japan carried out many years of research and development before taking its first steps in site selection.

H12: Project to Establish the Scientific and Technical Basis for HLW Disposal in Japan Project Overview Report
As outlined in the overall program for high-level waste (HLW) management in Japan, defined by the Atomic Energy Commission (AEC), HWL separated from spent nuclear fuel during reprocessing will be immobilized in a glass matrix and stored for a period of 30 to 50 years to allow cooling; it will then be disposed of in a stable deep geological formation.
Evaluating Site Suitability for a HLW Repository
Evaluating Site Suitability for a HLW Repository
The primary objective of government policy, and of NUMO in implementing this policy, is to
ensure that a repository for Japan’s high-level radioactive waste is located so as to provide
secure isolation of the waste and adequate safety for present and future generations. This
means that the site has to be chosen carefully, taking full account of all its characteristics. In
order to address these characteristics in an orderly and structured manner, we have established

H12: Project to Establish the Scientific and Technical Basis for HLW Disposal in Japan Supplementary Report Background of Geologic Disposal
Radioactive waste is produced from a wide range of human activities. The wastes arising from the nuclear fuel cycle occur as a wide range of materials and in many different physical and chemical forms, contaminated with varying activities of radionuclides. Their common feature is the potential hazard associated with their radioactivity and the need to manage them in such a way as to protect the human environment. The safe disposal of radioactive waste is a key reequirement of the nuclear industry worldwide.
The NUMO Structured Approach to HLW Disposal in Japan
The NUMO Structured Approach to HLW Disposal in Japan
The constraints set by the Japanese HLW disposal programme – particularly associated with
the decision to initiate siting by an open call for volunteers to host a geological repository –
pose particular challenges for repository project management. In order to maintain the
flexibility required to respond to the conditions found at volunteer sites, NUMO has not
published reference designs or site characterisation plans, as is normal for programmes
progressing by site nomination. Instead, we have developed a methodology – the NUMO

Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, Second National Report of Lithuania in Accordance with Article 32 of the Convention
Lithuania has signed this Convention on 30 September 1997 and ratified it on 18 December 2003. This Convention entered in force in Lithuania on 14 June 2004. This is the second report of Lithuania for this Convention. The aim of the report is to give the information on the fulfillment of obligations of this Convention to other Contracting Parties. This report will be discussed in the Third Review Meeting to be held in Vienna on 11-22 May 2009. This report was prepared according the Guidelines Regarding the Form and Structure of National Reports.

Impact of Nuclear Information on Young People's Knowledge and Attitudes: Methods/Participatory tools in an Educational Program WP1
Despite in Romania nuclear research activities were started in early 50s, the nuclear power is very young. First NPP, Cernavoda Unit 1, about 600 MWe, was in operation since 1996. Next unit (Cernavoda Unit2) will be in operation at the end of 2007. Therefore, a relative low amount of high level waste was produced. However, some problems already exists in Romania, mainly related to historical radioactive wastes released by nuclear industry and research.

Geological Problems in Radioactive Waste Isolation Second Worldwide Review Part 2 Ch 10 - 17
The first world wide review of the geological problems in radioactive waste isolation was published by Lawrence Berkeley National Laboratory in 1991. This review was a compilation of reports that had been submitted to a workshop held in conjunction with the 28th International Geological Congress that took place July 9-19,1989 in Washington, D.C.

Nuclear waste management from a local perspective: Reflections for a Better Governance Final Report
Nuclear waste management from a local perspective: Reflections for a Better Governance Final Report
During the 1990s, nuclear waste programmes in nearly every concerned country met many difficulties. Nuclear waste management was seen as a technical issue, and the local communities were only involved in the last stage of the decision-making process when almost all components of the decision were already fixed. The management of high level radioactive waste is now recognised as a complex decision-making process entailing technical, ethical, social, political and economic dimensions where no solution can be reached solely on the basis of technical considerations.

Summary of National and International Radioactive Waste Management Programs 1979
Many nations and international agencies are working to develop improved technology and industrial capability for nuclear fuel cycle and waste management operations. The effort in some countries is limited to research in university laboratories on treating low-level waste from reactor plant operations.
