Decommissioning of Facilities - Assistance to Member States


Publications address both technological aspects of decommissioning, including techniques for measuring levels of radioactivity, and decontamination and dismantling of plant and structures, as well as non-technological aspects such as planning, cost estimation and project management.

The decommissioning publications can be downloaded on the publications page, where the publications are organised according to the following themes:

  • Technology;
  • Management;
  • Implementation;
  • Development; and
  • Special Topics.

Management of Human Resources during Decommissioning with a Focus on Motivation Aspects

Over the years there has been increasing attention paid to the organisational and human factors that are an integral part of a nuclear organisation, contributing to its successes and failure in both safety and business performance. With motivated staff it is not only levels of output that improves, motivated staff work to higher standards of quality as they care what they are doing, learn faster and have more ideas. They are less likely to be involved in accidents, make mistakes or get involved in conflicts.

The IAEA has published guidance on all aspects of organisational and human factors along with the consideration of nuclear safety culture. This document (in an early phase of elaboration) forms part of this suite of guidance, focusing on the motivational factors that directly affect the safe and successful decommissioning of nuclear facilities.[top]

Lessons Learned from Deferred Dismantling of Nuclear Facilities

The objective of this report will be to provide information, experience and assistance on how to plan for a safe enclosure strategy and manage nuclear facilities after they have been transformed into Safe Enclosures and what needs to be considered in the decommissioning plans. Technical aspects will be those mainly addressed in this report. Safety and security considerations will be briefly introduced with relevant IAEA references provided.[top]

Decommissioning of Particle Accelerators

Nearly all Member States use particle accelerators for medical industrial and research applications. Over a service lifetime that can reach decades, accelerators become activated through the impact of (primary and secondary) particles on equipment and structures. Surface contamination may result from deposition of radioactive substances e.g. aerosols on accelerator components and nearby structures. In a longer term, this is a decommissioning issue. Noteworthy, the radioactive inventory – and the scale of decommissioning – are strongly dependent on the type of the accelerators, ranging from almost nil to significant.

Although cases of accelerator decommissioning have been sporadically described in the technical literature, no systematic treatment of decontamination/dismantling strategies/technologies for all types of accelerators is available. The report is intended to collect information on experience and lessons learned from implementation of decommissioning projects for particle accelerators. Based on this information, and highlighting typical issues and concerns, the report will provide practical guidance for all those having a role in this process.[top]
