DRiMa Project

International Project on Decommissioning Risk Management

Background

During the implementation of the two IAEA International Projects on decommissioning safety assessment (DeSa, 2004-2007, and FaSa, 2008-2011) it was recognized that in addition to the safety and technology challenges in decommissioning, management of project risks in decommissioning is an important area that requires more attention.

There was a demonstrated need to collect and exchange related experiences and to provide recommendations on application of risk management methodology to decommissioning projects. This data would assist decommissioning planners and implementers in making well-informed project-related decisions. In recognition of this need, the IAEA launched a new International Project on Decommissioning Risk Management - DRiMa.

The DRiMa project commenced in 2012 andand was completed in 2015.

Scope

The term "risk" in the context of the DRiMa project included all the relevant types of project related risks (strategic, political, organizational, regulatory, technical, safety, commercial/financial, stakeholder related, etc.) that may affect the progress of a decommissioning project, cause delays, and/or jeopardize the achievement of the project objectives. The project addressed risk management in decommissioning based on the existing risk management methodologies applied in other industries and based on their application within the decommissioning projects in the Member States. It covered management of risks at two levels – strategic and operational.

DRiMa project reviewed and defined the factors that influence decommissioning project risks, such as assumptions, constraints and interdependencies. It illustrated how a graded approach can be incorporated and used within the risk management methodology, and how this can result in the effective use of the available resources and in reduction of the overall project risk.

Objectives

The DRiMa project aimed to:

  • Collect and analyse experiences in management of risks related to decommissioning projects
  • Examine the applicability of risk management methodologies applied in other industries
  • Provide recommendations based on collection and analysis of the above
  • Illustrate the application of risk management in specific decommissioning tasks and actions
  • Aid decision making on strategic and operational levels for planning and implementation of decommissioning
  • Promote and encourage the sharing of risk management experience among participants

Outcome

One outcome of the project was establishment of recommendations on risk management for the decommissioning of facilities using radioactive material. These recommendations provided Member States with practical examples of the practices and procedures used for risk management in the planning and execution of decommissioning.

Specific outcomes of the project included:

  • Identification of good practices based on Member States’ experiences in project risk management, including examples from the application of risk management methodologies in other industrial sectors
  • Recommendations for application of the general risk management methodology to decommissioning, and on maintenance of a risk management system for decommissioning
  • Illustration of the role of risk management for decision making related to planning and execution of decommissioning of nuclear facilities
  • Illustration of the optimization of risk treatment strategies and how these can minimize threats and maximize opportunities during decommissioning. This would include development of contingency plans
  • Improved information exchange and enhanced capacities in the Member States for decommissioning risk management

The project outcomes and related recommendations are summarized in the project report (draft available here). Supporting information and practical examples drawn from Member States’ national experiences are provided in the draft report.

Project implementation

The DRiMa project was scheduled to run for three years. It was launched during the First Annual Meeting of the DRiMa project was held in Vienna from 17 to 21 December 2012. An Interim Meeting of the Working Groups was held in Cologne, Germany, from 13 to 16 May 2013, followed by a meeting of the Coordination Group of the DRiMa project. The Second Annual Meeting was held in Vienna from 7 to 11 October 2013. In 2014 an Interim Meeting of the Working Groups and a meeting of the Coordination Group was held in Zadar, Croatia, 2-6 June. The Third Annual Meeting of the DRiMa project was held from 17 to 21 November 2014, at the premises of the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) in Cologne, Germany. The Third Interim Meeting of the Working Groups and a meeting of the Coordination Group was held in Brussels, Belgium, 8-12 June 2015. The Fourth (and the final) Annual Meeting of the DRiMa project was held in Vienna from 2 to 6 November 2015.

The project was implemented through the individual meetings of project working groups and through the annual DRiMa technical meetings where the working groups met collectively.
