This paper critically considers the history of nuclear energy in Australia, placing particular emphasis on the strong debate about uranium mining and exporting which occurred between the late 1960s and early 1980s. Though this topic has been already analyzed by different historical studies and through numerous methodological approaches, some issues of the Australian as well as international ‘atomic debate’ which involved civil uses of nuclear power in the second half of the 20th century remain under-investigated. This article, for instance, focuses on the little-known and seldom popularized history of Synroc which, in the late 1970s, was presented as the ‘geological perspective’ to deal with radioactive waste disposal. The matters under discussion here are particularly important because of their links with some key issues still prevalent in the international nuclear debate, such as nuclear safety, atomic weapons proliferation and the safe disposal of nuclear wastes.

Abstract. The Federal Office for the Safety of Nuclear Waste Management (BASE – Bundesamt für die Sicherheit der nuklearen Entsorgung) is the German federal regulatory authority for radioactive waste disposal. It supervises the German site selection process and is responsible for the accompanying public participation. Task related research is an integral part of BASE's activities. The projects MessEr and übErStand compiled the state-of-the-art science and technology regarding surface based exploration methods suitable for addressing the criteria and requirements specified in the German Site Selection Act. The results support BASE to review and define the surface-based exploration programs to be executed by the national implementer BGE (Bundesgesellschaft für Endlagerung mbH). To support BASE in reviewing the application of the exclusion criteria “active fault zones” according to the Site Selection Act, the project KaStör reviewed the current knowledge on active faults and fault zones in Germany and recommends methodological approaches to date and identify the activity of faulting. For the time being, the Site Selection Act defines 100 ∘C as a draft limit on the temperature at the outer surface of a repository container for all host rocks. The project Grenztemperatur studied the temperature dependency of the different thermal-hydraulic-mechanical-chemical/biological (THMC/B) processes according to available features-events-processes (FEP) catalogues for rock salt, clay stone, and crystalline rock and describes ways to defining host rock specific maximum temperatures based on specific disposal and safety concepts. Safety oriented weighting of different criteria and comparison of different potential regions and sites are key challenges during the siting process. The project MABeSt studied and reviewed methodological approaches to this weighting and comparison problem with special emphasis on multi criteria analysis (MCA) and multi criteria decision analysis (MCDA). A key requirement for safe geological disposal of nuclear waste is barrier integrity. The project PeTroS performed the first triaxial flow-through experiments on natural rock salt samples at disposal relevant p−T conditions and studied potential percolation mechanisms of fluids within rock salt. The data substantiate that the minimum stress criterion and/or the dilatancy criterion are the prime “percolation thresholds” in rock salt. The research results support BASE in fulfilling its tasks as national regulator according to state-of-the-art science and technology and are also relevant to other stakeholders of the siting process.

This article examines the emergence of an unusual coalition of opponents and proponents of nuclear power, united in their insistence that the EU's high-level radioactive waste (HLW) be disposed of within the EU, and in their opposition to the export of HLW beyond the EU. We argue that this odd coalition is best understood by considering the waste disposal issue within the context of the industry's entire production chain. The activist-industry consensus represents a coalition of “baptists and bootleggers, once removed” brought together not by opposition to HLW exports per se, but rather by the intersection of the issue of radioactive waste disposal with that of nuclear power generation. For quite different reasons, both partners believe that internalizing the EU's radioactive waste is more likely than export to advance their respective goals, be it the expansion or elimination of nuclear power.

Intensive development of the nuclear power generation industry creates the issue of radioactive waste disposal (RAW), which has a negative impact on the environment. Development of uranium deposits using underground mines produces openings, e.g. workings and stopes that can be used as reservoirs for RAW storage. This requires a geomechanical assessment of the condition of mine workings and stopes, evaluation of their total volume, compliance with the requirements for the nuclear waste disposal sites, necessary preparation, as well as evaluation of the limits of existing mining technologies and equipment.
