Decommissioning of nuclear installations

04/12/2023 - 08/12/2023
Boeretang 201


As the final step of the nuclear facility life, decommissioning differs quite significantly from the operational period of life. Changing environment, development of new tools, “one shot” operations, production of huge amounts of waste, discrepancies between original design and the final layout of the facility, need for a global risk management with evolving radiation protection programme are some characteristics operators, health physicists, technicians are faced with when processing with dismantling operations. Moreover, regulatory requirements, choice for a dismantling strategy, safety and waste management, assessment and follow-up of doses, financial provisions and human resources management give still rise to many questions when a decommissioning project has to be set up.

The main objective of the training course is to provide the participants with the basic requirements regarding the management of a decommissioning project and to share experience from ongoing decommissioning projects.

This course frames within the European ELINDER project (European Learning Initiatives for Nuclear decommissioning and Environmental Remediation).

Lectures will be provided by several SCK CEN experts.


The lectures will address the following topics:

  • Legal and regulatory framework;
  • Strategies for decommissioning;
  • Decommissioning project management;
  • Safety aspects and management;
  • Inventory, facility and site characterization;
  • Case studies (BR3,BN,Thetis);
  • Dismantling operations;
  • Optimization tools;
  • Material management and characterization;
  • Final survey plan and safety report;
  • Decontamination techniques.

The course will be given face-to-face. In addition to lectures, ample time is foreseen for practical exercises, group discussions and technical visits.

Groupe cible

All stakeholders such as regulators, plant managers and operators, health physicists, technical support organisations (already involved by decommissioning operations or planning such operations in the coming months of years) should take benefit from this event whose main aim is to be as close as possible to the practices by sharing experience from ongoing decommissioning projects.
