Regional Workshop on Complementary Safety Assessment of Research Reactors Following the Lessons Learned from the Fukushima Daiichi Accident
9–13 December 2013
BackgroundIn the two years since the Fukushima Daiichi accident, IAEA Member States have been carrying out safety reassessments (‘stress tests’) of their nuclear installations to evaluate their ability to withstand the effects of extreme external events that had previously not been considered in the design basis. Although the primary focus of these reassessments has been on nuclear power plants, many Member States have extended the scope of safety reassessments to include research reactors.
The International Conference on Research Reactors: Safe Management and Effective Utilization that was held in Rabat, Morocco, from 14 to 18 November 2011 recommended that the operating organizations of research reactors take a proactive approach towards examining their design basis and safety analysis to evaluate what, if any, changes and improvements should be made to withstand multiple severe external events as appropriate for their site and facility characteristics. The conference also recommended that a meeting be organized by the IAEA to discuss the methods and results of ‘stress tests’ carried out on research reactors and to prepare a summary of the results and lessons of post-Fukushima safety analyses. In response to these recommendations, the IAEA organized the Technical Meeting on the Implications of the Fukushima Daiichi Accident on the Safety of Research Reactors at its Headquarters in Vienna, Austria, from 14 to 18 May 2012. Reports on safety reassessments and actions carried out or planned in the light of the Fukushima Daiichi accident were provided by 27 countries, reflecting an important part of the research reactor community’s response to the accident.
In order to promote harmonization of the approach towards safety reassessments of research reactors taking into account the feedback from the Fukushima Daiichi accident, a guidelines document was drafted in May 2012 and reviewed by the participants in the above-mentioned Technical Meeting. After incorporation of the comments and changes recommended by the participants and internal review by the IAEA Secretariat, the guidelines will be published as an IAEA Safety Report with the title: Safety Reassessment for Research Reactors in the Light of the Accident at the Fukushima-Daiichi Nuclear Power Plant. This Safety Report was approved and is currently in printing.
The Regional Workshop on Complementary Safety Assessment of Research Reactors Following the Lessons Learned from the Fukushima Daiichi Accident will take place at the Argonne National Laboratory, United States of America, from 9 to 13 December 2013. The participants in this workshop will discuss, exchange information and share knowledge on the performance of safety reassessments, the results of these reassessments, the implications of the Fukushima Daiichi accident on research reactor operation and utilization, and the actions that need to be taken by Member States.
Objectives of the WorkshopThe objective of the ANSN workshop is to provide the participating Member States with practical knowledge and information on performing safety reassessments of research reactors in the light of the feedback from the Fukushima Daiichi accident, with a focus on methods and approaches for performing analysis of extreme external events, combined and consequential events, and beyond design basis events for different reactor types. The participants from each country will be expected to provide a presentation on the results of safety reassessments (completed, in progress or planned) of research reactors based on the experience from the Fukushima-Daiichi accident. The presentations should address the successful methods and approaches used in the safety reassessments of beyond design basis events, such as extreme external events, combined and consequential events, as well as areas in which difficulty was encountered or assistance is needed. The presentations should address the following topics outlined in the above-mentioned and soon to be published Safety Report, as appropriate:
- Regulatory aspects of the safety reassessment
- Reassessment of the reactor facility:
- Review of the design basis of the reactor facility
- Assessment of beyond design basis events
- Reassessment of the site:
- Review of the site characteristics
- Site-wide events
- Reassessment of the emergency preparedness and response arrangements
- Application of a graded approach
- Implementation of the safety reassessment findings
Nature of the WorkshopThe workshop will consist of lectures, country report presentations and working group sessions. The workshop will include presentations by IAEA representatives on the status of the IAEA’s response to the Fukushima Daiichi accident with respect to the implications of the accident on research reactor safety and feedback from the recent relevant IAEA activities. Additional presentations by IAEA representatives and external experts will be provided to address methods and approaches for performing safety reassessments. Participants’ working groups will be formed to discuss and compare the methods, approaches and results of their safety reassessments and ways to improve the safety reassessment of research reactors in cases of extreme external events. Discussions in the working groups will cover the identification of methods and approaches, as well as issues and challenges of common concern and possible means to address these challenges.
The information will be available soon.
