Regulatory approach and nuclear safety requirements for termination of operations and decommissioning of nuclear power plants in Lithuania

The decision to shut down Unit 1 of the Ignalina Nuclear Power Plant (INPP) was taken on 5 October 1999, when the 'National Energy Strategy' was adopted by the Seimas (Parliament). In the accession negotiations and according to the position statement, Lithuania has committed to the closure of Unit 2 by 2009. The European Union is in solidarity with Lithuania and is ready to continue to provide adequate additional assistance for the decommissioning effort even after Lithuania's accession to the European Union.The early termination of operations at INPP initiated an elaboration: of the policy; requirements; guidance; capabilities of the regulatory bodies; and technical support organizations in the area of decommissioning safety, waste management, disposal strategy, and the technology of dismantling. A legal basis has been promulgated and regulatory documents issued. Planning has been performed. However, a lack of experience specific to RBMK reactors, and limited financial and human resources, have created an environment of concern with regard to the current uncertainties. VATESI is looking forward to solving the remaining problems using the practices of other countries. The paper describes the activities of the Lithuanian authorities in the establishment of the regulatory framework, the approach for the licensing process, safety assessment of decommissioning projects, and overseeing the safety issues in the final phase of the entire nuclear fuel cycle.
