Experience from decommissioning projects suggests that the decommissioning of nuclear power plants could be made easier if it received greater consideration at the design stage and during the operation of the plants. Better forward planning for decommissioning results in lower worker doses and reduced costs. When appropriate design measures are not taken at an early stage, their introduction later in the project becomes increasingly difficult. Hence, their early consideration may lead to smoother and more effective decommissioning. It is now common practice to provide a preliminary decommissioning plan as part of the application for a licence to operate a nuclear facility. This means, in turn, that decommissioning issues are being considered during the design process. Although many design provisions aiming at improved operation and maintenance will be beneficial for decommissioning as well, designers also need to consider issues that are specific to decommissioning, such as developing sequential dismantling sequences and providing adequate egress routes. These issues and more are discussed in this report.
