Description
Ignalina INPP has two units with RBMK-1500 reactors. Unit 1 was shut down in 2004 and Unit 2 – in 2009. Pursuant to the provisions of the Law on Nuclear Safety the Ignalina NPP Units operation licences are valid as long as nuclear fuel is there. All spent nuclear fuel is removed from the Unit 1 and Unit 2 storage pools to a dry storage facilities in 2022.
The State Enterprise Ignalina NPP (thereinafter – SE Ignalina NPP) during transition period from operation to decommissioning undertake activities to prepare for decommissioning as well as building necessary infrastructure for radioactive waste management. Implementation of a number of dismantling and decontamination (D&D) projects related to equipment no more needed started at this transition period as well. State Nuclear Power Safety Inspectorate (thereafter – VATESI) developed legislative framework allowing to proceed dismantling activities within the frame of operational licence. Hence, authorisation of decommissioning activities is implemented by the granting of the licence for decommissioning as well as granting permissions for individual dismantling and decontamination projects.
Safety evaluation is a key issue for authorisation of decommissioning activities. Aspects of a safety assessment for granting of decommissioning licence as well as authorisation of dismantling and decontamination projects (e.g. overview of content of safety analysis reports) based on exemples from Ignalina NPP decommissioning projects to be presented.
VATESI established procedures for authorization of release of buildings and site from regulatory control, including site and buildings investigation process and required VATESI agreements on radiological characterization programmes and reports. Main aspects of this process to be presented.
