The decommissioning plan of the Ignalina Nuclear Power Plant established the Programme work breakdown structure (Ignalina Nuclear Power Plant Decommissioning Activity and Projects Decomposition Hierarchical Structure). The first level of that structure consists of the following six items:
|
(a)
|
P.0 ‘Enterprise activity organisation’;
|
|
(b)
|
P.1 ‘Decommissioning preparation’;
|
|
(c)
|
P.2 ‘Facility dismantling/demolition and site restoration’;
|
|
(d)
|
P.3 ‘Spent Nuclear Fuel handling’;
|
|
(e)
|
P.4 ‘Waste handling’;
|
|
(f)
|
P.5 ‘Post-operation programme’.
|
Item P.0 ‘Enterprise activity organisation’ covers the enterprise management, surveillance and quality assurance, radiation and ecological monitoring, physical security, engineering consultancy and legal support for enterprise activities and public communication.
Item P.1 ‘Decommissioning preparation’ covers the provision of preliminary conditions for decommissioning (such as equipment inventory and radiological characterisation), the modification of infrastructure, the installation of equipment and the construction of facilities, the isolation of systems and equipment, and the decontamination of process systems, equipment and facilities.
Item P.2 ‘Facility dismantling/demolition and site restoration’ covers the dismantling of reactors, the dismantling of process equipment/systems and waste pre-treatment, the demolition of facilities, and site restoration.
Item P.3 ‘Spent Nuclear Fuel handling’ covers spent nuclear fuel handling and storage.
Item P.4 ‘Waste handling’ covers the treatment, conditioning, storage and disposal of very low, low and intermediate-level radioactive waste resulting from the operational and decommissioning activities.
Item P.5 ‘Post-operation programme’ covers the operation and maintenance of facilities, energy resources, the water supply, sewage and water purification.
