CONFIDENCE dissemination meeting: summary on the scenario-based workshop

The CONFIDENCE dissemination workshop “Coping with uncertainties for improved modelling and decision making in nuclear emergencies” was held in December 2–5, 2019 (Bratislava, Slovak Republic). About 90 scientists and decision makers attended the workshop. The dissemination workshop allowed the presentation of the CONFIDENCE project results, demonstration of the applicability of the developed methods and tools in interactive discussion sessions and the collection of feedback from the participants. The results were disseminated not only in the form of presentations and posters but also through interactive workshops where all participants were involved in round table working groups. A fictive accidental release scenario taking place at a nuclear power plant was developed and used by each work package in the workshop to provide the basis for interactive sessions and discussions

The work programme of NERIS in post-accident recovery

NERIS is the European platform on preparedness for nuclear and radiological emergency response and recovery. Created in 2010 with 57 organisations from 28 different countries, the objectives of the platform are to: improve the effectiveness and coherency of current approaches to preparedness; identify further development needs; improve "know how" and technical expertise; and establish a forum for dialogue and methodological development. The NERIS Strategic Research Agenda is now structured with three main challenges: (i) radiological impact assessments during all phases of nuclear and radiological events; (ii) countermeasures and countermeasure strategies in emergency and recovery, decision support, and disaster informatics; and (iii) setting up a multi-faceted framework for preparedness for emergency response and recovery. The Fukushima accident has highlighted some key issues for further consideration in NERIS research activities, including: the importance of transparency of decision-making processes at local, regional, and national levels; the key role of access to environmental monitoring; the importance of dealing with uncertainties in assessment and management of the different phases of the accident; the use of modern social media in the exchange of information; the role of stakeholder involvement processes in both emergency and recovery situations; considerations of societal, ethical, and economic aspects; and the reinforcement of education and training for various actors. This paper emphasises the main issues at stake for NERIS for post-accident management

Emergency preparedness for long lasting releases – overview and conclusions

The Fukushima accident has demonstrated the possibility of long-lasting releases of radionuclides from a nuclear power plant over several weeks. Within the framework of the “PREPARE” research project one work package focused on testing emergency preparedness arrangements in various countries for the special case of long lasting emissions. The aim of this study was to test whether protection strategies included in current nuclear emergency planning in various European countries could adequately reduce the radiological consequences of Nuclear Power Plant accidents with long lasting severe releases. This paper presents an overview and the conclusions of this study, more details of the work can be found in the following articles

Assessing radiation risk perception by means of a European stakeholder survey

It is increasingly recognized that stakeholder views can be essential to ascertain the credibility of those entrusted with protection of the public and workers against radiation risks, the robustness of the approaches to protection and the relevance of research underpinning radiation protection. The CONCERT European Joint Programme of radiation protection research included consideration of stakeholder views. These were surveyed by means of a publicly available survey that was made available in fifteen languages to help encourage responses from a wide range of European countries. The survey ran in 2017 and received some 1961 responses over many countries, though response rates varied widely between countries. The survey respondents were largely highly educated with many having a professional connection to radiation protection or the use of radiation in medicine or industry. Survey results indicated a high level of scientific/technical knowledge relevant to radiation protection and indicated a general trust of most actors involved in the radiation protection field, perhaps unsurprisingly given the nature of the sampled population. Most expressed a reasonable level of satisfaction with the information available to them on radiation risk, but there is clearly room for improvement. Additionally, the survey identified potential training needs amongst the groups responding. It is concluded that, while the survey results are limited by the non-representativeness of the respondents by comparison with the EU population as a whole, it has been successful in gaining insights into areas where communication could be improved, where professional training gaps are present and where research could help to build wider trust in radiation protection

Decision aiding handbooks for managing contaminated food production systems, drinking water and inhabited areas in Europe.

Three handbooks have been developed, in conjunction with a wide range of stakeholders to assist in the management of contaminated food production systems, inhabited areas and drinking water following a radiological incident. The handbooks are aimed at national and local authorities, central government departments and agencies, emergency services, radiation protection experts, the agriculture and food production sectors, industry and others who may be affected. The handbooks include management options for application in the different phases of an incident. Sources of contamination considered in the handbooks include nuclear accidents and radiological dispersion devices; the most relevant radionuclides are included. The handbooks are divided into several sections which provide supporting scientific and technical information; an analysis of the factors influencing recovery; compendia of comprehensive, state-of-the-art datasheets for around 100 management options and guidance on planning in advance. A decision-aiding framework comprising colour coded selection tables, look-up tables and decision trees and several worked examples are also included. The handbooks can be used as a preparatory tool, under non-crisis conditions, to engage stakeholders and to develop local and regional plans. The handbooks can also be applied as part of the decision-aiding process to develop a recovery strategy following an incident. In addition, the handbooks are useful for training purposes and during emergency exercises. To realise their full potential, the handbooks should be customised at national, regional and local levels

Stakeholder involvement through national panels and surveys to address the issues and uncertainties arising in the preparedness and management of the transition phase

Under the framework of the CONFIDENCE project, work package 4 was focusing on the transition to long-term recovery, involving stakeholders in decision-making processes. The essential research was performed using a participatory approach, which combined scenario-based stakeholder discussion panels and transnational stakeholder surveys following the Delphi methodology. The objective was to identify and address the issues and uncertainties arising in the preparedness and management of the transition phase and to explore ways to facilitate the incorporation of stakeholders' expertise, points of view and interests in the decision-making processes. The final goal was to build best practices for planning optimal remediation strategies during the transition phase considering stakeholder involvement in the decision-making process. The results obtained from the work undertaken in nine European countries are presented.</p
