The Creation

Trends in the development of the nuclear-industrial complex and radioactive waste management are analyzed. Among the main problems of development of the nuclear-industrial complex and radioactive waste management are the imperfection of the legal framework, lack of investment. The contribution of the nuclear industry of Ukraine to the creation of gross domestic product is not significant, but its role is important in ensuring economic security and achieving energy independence of the country. The state of the nuclear-industrial complex in other countries of the world has been studied. It is expedient to use an innovative approach for the development of the nuclear-industrial complex. This approach is presented as a set of three interrelated blocks, namely: methodological and informational; diagnostic and orientation; evaluation and procedural. Directly, the nuclear-industrial complex, which is a leading link in the nuclear-energy complex of Ukraine, can be considered a complex sector of the national economy, including: uranium production, which creates a basis for meeting the needs of nuclear power plants in natural uranium in the medium and long term; zirconium production, which involves the establishment of zirconium production. The results of the implementation of the regional program for the development of the nuclear-industrial complex should include the following: increasing the competitiveness of enterprises in key strategic industries: nuclear, mining, metallurgy, chemical and mechanical engineering; increasing the innovation of production through the development of scientific potential of the region, the commercialization of the scientific process; development of enterprises on the basis of the latest technologies of industrial waste processing, including for the development of the region's infrastructure; reduction of man-caused load on the environment; creating more attractive and diverse jobs; ensuring the stabilization of social processes in the mining regions. One of the directions of modernization of the nuclear-industrial complex of Ukraine is the creation of SMR reactors (Smallmodularreactor) and its installation instead of the existing ones. Their production must be carried out at Ukrainian enterprises. The necessity of increasing the volume of uranium production, the level of its enrichment and at the same time solving environmental issues on waste disposal is substantiated.

Potential Health

In Central Asia (CA) the radioactive waste comes mainly from uranium mining and milling, nuclear weapon testing and nuclear power development and other ionizing sources. This waste was produced, to a greater extent, by the military-industrial complex and the uranium and non-uranium industry, and, to a lesser extent, by the nuclear industry and in the process of use of isotope products. Exploitation and mining of uranium and thorium deposits produce a large amount of solid and liquid radioactive waste, as well volatile contaminants which need a proper management. In Central Asia the wastes are mainly stored at the surface in large piles and represent a long-term potential health and environmental hazard. The process of remediating legacy sites of the past and reducing the threats is now getting under way, with the design and implementation of remediation activities, partly with international support. However, there is a significant lack in the regulatory basis for carrying out such remediation work, including a lack of relevant radiation and environmental safety norms and standards, licensing procedures and requirements for monitoring etc., as well as expertise to transform such a basis into practice. Accordingly, the objective of the proposed project is to assist the relevant regulatory authorities in Kazakhstan, Kirgizstan and Tajikistan to develop national robust and adequate regulations and procedures, taking into account the international guidance and Norwegian experience with regulatory support projects in Russia. Specific expected results in the project period include: a threat assessment report identifying priority areas for regulatory development, based on the status of current regulatory documents and the hazard presented by the different sites and facilities; development of national radioactive waste management strategies in each country; development of an enhanced regulatory framework for supervision of nuclear matters, and an enhanced safety culture.

This paper provides an overview of the current status of radioactive waste management in the UK from the point of view of Nirex, the organisation responsible for providing safe, environmentally sound and publicly acceptable options for the long-term management of radioactive materials. Essentially, it argues that: • the waste exists and must be dealt with in an ethical manner; • legitimacy is the key to public acceptance of any attempt to solve the waste issue; and • credible options and a new political will allow, and indeed, compel this generation to deal with it. In doing this, the paper takes account of a number of recent announcements and ongoing developments in the UK nuclear industry, in particular: • the recent announcement that Nirex is to be made independent of industry; • the Department of Environment, Food and Rural Affairs and Devolved Administrations’ Managing Radioactive Waste Safely consultation exercise; • the creation of the Committee on Radioactive Waste Management to oversee the consultation; • the creation of the Nuclear Decommissioning Authority to manage the civil nuclear site clean-up programme; • proposals for improved regulation of Intermediate Level Waste conditioning and packaging; and • proposals by the European Commission for a new radioactive waste Directive. These institutional and policy changes amount to an evolution of the back-end of the fuel cycle that represents the most radical transformation in the UK nuclear industry for many years. In a large part, this is a transformation made necessary by past failures in trying to impose a solution on the general public. Therefore, in order for these changes to result in a successful long-term radioactive waste management programme, it is necessary to pay as much attention to political and social concerns as scientific and technical ones. Primarily it is crucial that all parties involved act in an open and transparent manner so that the decisions made achieve a high degree of legitimacy and thus public acceptance. Crucially too, the problem must be framed in the correct term — that the waste exists irrespective of the future of nuclear power and that this is an issue that must be addressed now. Thus there is a legitimacy of purpose and scope in moving forward that addresses the ethical imperative of this generation dealing with the waste. Put together with the action the government is taking to create the necessary institutional framework, Nirex believes that for the first time in a generation the UK has the building blocks in place to find a publicly acceptable, long-term solution for radioactive waste.

ABSTRACTAn overview is given on research activities on cementitious materials for radioactive waste management systems based on the IAEA Coordinated Research Project (CRP) held in 2007-2010. It has been joined by 26 research organizations from 22 countries which shared their research and practical activities on use of cementitious materials for various barrier purposes. The CRP has initially formulated the research topics considered within four specific streams: A) Conventional cementitious systems; B) Novel cementitious materials and technologies; C) Testing and waste acceptance criteria; and D) Modelling long term behaviour.The CRP has analysed both barrier functions and interactions envisaged between various components with focus on predisposal stage of waste management. Cementation processes have achieved a high degree of acceptance and many processes are now regarded as technically mature. A large body of information is currently available on proven waste conditioning technologies although novel approaches are continuing to be devised.Most of the existing technologies have been developed for conditioning of large amounts of operational radioactive waste from nuclear power plants and other nuclear fuel cycle facilities. However new waste streams including those resulting from legacy and decommissioning activities required improved material performance and technologies.The most important outcome of CRP was the exchange of information and research co-operation between different institutions and has contributed towards general enhancement of safety by improving waste management practices and their efficiency. The paper presents the most important results and trends revealed by CRP participants. The research contributions of participating organizations will be published as country contributions in a forthcoming IAEA technical publication.

ABSTRACTSince its creation in 1950, the Argentine Atomic Energy Commission (CNEA), has worked on the development of applications for the peaceful use of nuclear energy. They include, among others, research and development activities in basic and nuclear technology areas, the operation of important facilities for the production of radioisotopes and the performance of tasks in connection with the nuclear fuel cycle, mining and uranium processing activities, manufacturing of fuel elements, production of heavy water and the operation of two nuclear power plants. Also demonstrating reprocessing programs have been developed.As a result of the above mentioned activities performed in the nuclear field by private and public entities, various types of radioactive waste have been and are produced during operation and maintenance of facilities and plants, and will be produced in their future decommissioning. CNEA is also responsible for the environmental remediation of the closed uranium mining and milling facilities and for the management of disused sealed sources from medical and industrial applications.Activities concerning radioactive waste management are carried on according not only to Nuclear Regulatory Authority requirements and International Atomic Energy Agency recommendations, but also to the national legal framework.The Law Nº 25.018, "Radioactive Waste Management Regime“(1998), created the National Program for Radioactive Waste Management (PNGRR), as part of CNEA organization.

The difficulty occurred in nuclear power plants that the accumulated radioactive solid waste is beyond the design capacity and unable to be sent to disposal is focused on in this paper. The deep reasons for the difficulty occurred are concluded to be the unclear responsibility for disposal of radioactive waste and the divided national function of nuclear power development and radioactive waste management, by analyzing the disposal demand of radioactive solid waste caused by continuous development of nuclear power and the current situation and existing problems for the disposal of low-intermediate level radioactive solid waste in China. The policy suggestions of issuing the disposal siting plan of radioactive solid waste, forming independent firms of radioactive waste storage and disposal and improving radioactive waste management fund system are proposed based on above analysis and investigation.
