Potential scenarios for broadening stakeholder involvement in the implementing geological disposal technology platform

This paper analyses the potential for the involvement of different types of stakeholders in the Implementing Geological Disposal Technology Platform (IGD-TP). This analysis was conducted as part of the InSOTEC project, a three-year (2011- 2014) collaborative research project funded under the 7. Euratom Framework Programme (Grant Agreement nr. 269906). In our analysis, we consider the extent to which the IGDTP's practice as regards to stakeholder involvement matches its discourse, and what potential for improvement exists given its structural organisation as a European Technology Platform (ETPs). Technology Platforms (TPs) can be understood as knowledge networks, deliberately set up to influence (research) policy in a specific domain. We therefore use knowledge networks as a conceptual approach and look at the IGD-TP as a complex network which includes actors, knowledge and practices across different countries, focusing on a very specific topic (i.e. implementing geological disposal). We compare the way different stakeholders are involved in the IGD-TP to the practice of other ETPs, and explore how the IGD-TP is viewed by its members and by outsiders to the platform Applying Callon's framework of knowledge co-production (1999) we come to define different degrees of interaction between science, society and policy in view of defining research and development (R and D) priorities [1]. Subsequently we describe how these interactions could be conceptualised and interpreted for the IGD-TP. The current approach of the IGDTP can be mainly understood as classical model involving mainly expert stakeholders and scientists. Where there seems to be a good representation among IGD-TP members of industry, research institutes, and some members of the academic community this is not the case for other types of stakeholders, such as public authorities or civil society. At this stage, the overall approach of the IGD-TP would seem to restrict the scope of stakeholder involvement, as it narrows participation down to uniquely technology experts, hindering socio-technical manifestations. Our analysis nevertheless shows that there is room for engaging with a broader range of stakeholders in the field of radioactive waste management, if this is the intention of the IGD-TP. However, this would require a commitment to developing a common knowledge base including other stakeholders through a process of mutual adjustment and negotiation. (authors)

Brexit, Euratom and Nuclear Liabilities - 18643

The outcome of the UK referendum on withdrawal from the European Union has resulted in a UK government decision that the UK must withdraw from Euratom. As at the date of the Waste Management Symposia, half of the 2-year programme for agreeing the terms of exit and putting in place replacement arrangements will have passed. If no agreement is reached by 29 March 2019 and no extension of that deadline is agreed the UK will automatically exit Euratom on that date. Aside from potential trade tariffs, Euratom exit will create binary questions on acceptability of nuclear trade and collaboration with the UK, reflecting current reliance on the UK's status as a Euratom member in establishing and implementing acceptable safeguarding requirements, ensuring inclusion of the UK within the scope of existing Euratom nuclear cooperation agreements, and as a basis for current UK bilateral nuclear cooperation agreements. This in turn risks disruption of international nuclear cooperation and trade, including provision of resources and know-how in support of the UK waste and decommissioning effort and international movement of waste for treatment. The paper will consider the current status of negotiations for UK withdrawal from Euratom, development of replacement safeguarding arrangements and replacement of international nuclear cooperation agreements essential to future nuclear cooperation and trade with the UK, taking into account: - the current and future legal basis of UK safeguarding obligations, including potential changes to the UK's Voluntary Offer Safeguards Agreement under the Non-Proliferation Treaty and likely acceptability of replacement arrangements to key nuclear trading partners; - practical arrangements for meeting those obligations post Euratom reliance via independent safeguarding arrangements; and - the need for and challenges in replacement of the UK's current reliance on its status as a Euratom member in taking the benefit of the existing US / Euratom s123 Agreement and other Euratom nuclear cooperation agreements. The paper will also provide a brief update on recent developments in international nuclear liabilities. The last 2 years have seen significant changes, with the Convention on Supplementary Compensation finally entering into force on 15 April 2015 and significant progress towards ratification of the 2004 Protocols to the Paris and Brussels Conventions. These changes are to be welcomed as beneficial to international cooperation, but also bring changes to liabilities risks associated with international movement of nuclear materials. Despite clear advances nuclear liabilities risks remain a significant consideration in negotiation of international nuclear contracts, recognising beneficial changes as well as on-going areas of risk and uncertainty.

Diagnostics for machine protection of DEMO

DEMO aims to (i) integrate, demonstrate and validate all relevant technology necessary to convert fusion energy to electrical energy and (ii) that the machine and its operations are economically and environmentally acceptable. To maintain the efficiency and availability of the machine, there are several physics and combined physics/technology issues as well as the engineering issues. Machine Protection (also known as Protection of Investment) addresses both the risks to plant (to avoid costly repair or replacement) and the risks to normal operating time (to avoid loss of productivity and the return on investment). The plasma-related Machine Protection issues involve measurement and control of plasma stability, plasma purity, and plasma-wall interactions. Machine Protection aims to avoid hitting catastrophic limits by using early warning alarm systems, and controlled termination or avoidance, involving coordinated actions of the magnets, gas and auxiliary heating or current-drive systems. This article outlines the key processes, some of which are used in present-day tokamaks and some of which are new specifically for DEMO (e.g. First wall and divertor power handling) and reveals the need to research and develop new science and technology for Machine Protections in DEMO's high radiation and thermal fields. This work was funded by the RCUK Energy Programme under grant EP/I501045 and the European Communities under the contract of Association between EURATOM and CCFE and conducted partly under EFDA PPPT (WP13-DAS04).

The EU Approach for Responsible and Safe Management of Spent Fuel and Radioactive Waste - 12118

In July 2011 legislation on responsible and safe management of spent fuel and radioactive waste was adopted in the European Union (EU). It aims at ensuring a high level of safety, avoiding undue burdens on future generations and enhancing transparency. EU Member States are responsible for the management of their spent fuel and/or radioactive waste. Each Member State remains free to define its fuel cycle policy. The spent fuel can be regarded either as a valuable resource that may be reprocessed or as radioactive waste that is destined for direct disposal. Whatever option is chosen, the disposal of high level waste, separated at reprocessing, or of spent fuel regarded as waste should be considered. The storage of radioactive waste, including long-term storage, is an interim solution, but not an alternative to disposal. To this end, each Member State has to establish, maintain and implement national policy, framework and programme for management of spent fuel and/or radioactive waste in the long term. Member States will invite international peer reviews to ensure that high safety standards are achieved. The EU approach is anchored in internationally endorsed principles and requirements of the IAEA safety standards and the Joint Convention and in this context makes them legally binding and enforceable in the EU. The EU approach of regulating the management of spent fuel and radioactive waste is anchored in the competence of the national regulatory authorities and in the internationally endorsed principles and requirements of the IAEA Safety Standards and the Joint Convention. Member States have to report to the Commission on the implementation of Directive 2011/70/Euratom for the first time by 23 August 2015, and every 3 years thereafter, taking advantage of the review and reporting under the Joint Convention. On the basis of the Member States' reports, the Commission will submit to the European Parliament and the Council a report on progress made and an inventory of radioactive waste and spent fuel present in the EU territory and the future prospects. Directive 2011/70/Euratom is a logical next step after the Council Directive 2009/71/Euratom on the nuclear safety of nuclear installations. The EU is the first major regional actor providing a binding legal framework on nuclear safety and on responsible and safe management of spent fuel and radioactive waste, and thus is a real model to progress spent fuel and waste management in a safe and responsible manner.
