4.13 Maintaining Effective Security during the Decommissioning of Nuclear Power Plants

This guide outlines the stages of decommissioning, the potential security risks and security arrangements to be implemented at each stage, including information security, cybersecurity and changing requirements for the physical protection system. It will also look at how to re-evaluate nuclear security requirements as decommissioning progresses and the inventory of nuclear and other radioactive material is reduced and the potential consequences from theft of radioactive material or sabotage of the facility change.

The target audience for this Best Practice Guide includes executives and other senior leaders who need to make decisions related to decommissioning from all sides including regulatory requirements, cost and effectiveness of the decommissioning strategy. It also includes security managers, nuclear facility managers, and other project managers who are either planning or undertaking decommissioning of a nuclear power plant.
