NorDec

Activity name NorDec - Challenges and opportunities for improving Nordic nuclear decommissioning
Project summary

Approaching large-scale nuclear decommissioning projects in the Nordic countries make it important for both regulators and operators to build new capabilities for handling up-coming challenges. Sweden and Finland both have a mixed legacy of nuclear sites, including plants and research reactors in different stages of operation or decommissioning, whereas in Denmark, some decommissioning projects have been completed for research reactors and others are well on the way to completion. In Norway, while no immediate decommissioning activities are foreseen, the existing decommissioning plans and regulations can be improved by means of the information and lessons learned from the other Nordic countries.

 

This project will conduct a study on how decommissioning is regulated, planned and performed in the Nordic countries, identify where the main challenges lie, collect best practices and share experiences between the Nordic participants. The contributions for this project will come from regulators, operators and contractors, thus having a wide span of stakeholder involvement. The Norwegian Radiation Protection Authority (NRPA), Swedish Radiation Safety Authority (SSM), Danish Health Authority (SIS), Finnish Radiation and Nuclear Safety Authority (STUK), the energy companies Fortum and Vattenfall, the consulting firm ŇF of Sweden, VTT Technical Research Center of Finland, and Institute For Energy Technology (IFE) in Norway are participating in the project. The project will involve collecting experiences from completed and ongoing decommissioning-related activities in Sweden, Finland, Denmark and Norway. The experiencesí evaluation aims to identify possible improvements in processes, methods and tools. The project will foster collaboration among Nordic stakeholders through sharing of challenges and best practices.

 

Activity 1: Decommissioning of Nordic legacy sites

Data collection to identify main challenges and best practices for planning of decommissioning of legacy sites in Nordic countries

  • Main challenges identified
  • Interactions between regulatory body, licensees and contractors regarding decommissioning approaches and practices
  • Lessons learned in a Nordic setting

 

Activity 2: Large scale decommissioning in a Nordic setting

Data collection to identify main challenges and best practices for planning of decommissioning of commercial reactors. Use Nordic experiences as well as the NorDec participants' collected knowledge of international lessons learned.

  • Interactions between regulatory body, licensees and contractors regarding decommissioning approaches and practices
  • Foreseen challenges and needs for future research and technology development
  • Experiences with international decommissioning that may be transferred to Nordic projects

 

Activity 3: Nordic collaboration arena

Comparisons based on an analysis of the insights from Nordic decommissioning regulators, utilities, contractors and research organizations. Specific and common issues and practices among and within Nordic countries from a regulatory, licensee, contractor and research organization perspective.

  • Common interests among Nordic countries for collaborative developments for solving issues and share experience and results, including adapting international lessons learned to a Nordic setting
  • Ways for shortening the gap between different stakeholders in each country by collaboration around identified issues
  • Issues and practices related to decommissioning strategy, e.g. immediate and deferred dismantling. Which considerations, such as radiation protection optimization, co-implementation of the decommissioning with other nuclear facilities, or the availability of disposal facilities, support the chosen strategy?
