Pursuant of modern concept on radioactive waste management applied in IAEA Member States all radioactive wastes produced during the BN- 350 operation and decommissioning are subject to processing in order to be transformed to a form suitable for long-term storage and final disposal. In accordance with the decision of Kazakhstan Government, three basic stages for BN- 350 reactor decommissioning are envisaged: First stage - Placement of BN- 350 into long-term storageīN- 350 decommissioning problems of radioactive waste management They are carried out to achieve a progressive and systematic reduction in radiological hazards and are undertaken on the basis of planning and assessment in order to ensure safety decommissioning operations. These actions involve decontamination, dismantling and removal of radioactive materials, waste, components and structures. Decommission is defined as a complex of administrative and technical actions taken to allow the removal of some or all of regulatory controls over a nuclear facility. Actions provided for in the plan include the following: Development of BN- 350 Reactor Decommissioning Plan Accident prevention during the period of transition Unloading nuclear fuel from reactor and draining the coolant from the heat exchange circuits. To determine the activities required for ensuring reactor safety and in preparation for decommission in the period prior, the development and ensuring approval by the Republic of Kazakhstan Government of the decommissioning plan, a 'Plan of Priority Actions for BN- 350 Reactor Decommissioning' was developed and approved.

Because the decision on reactor decommissioning was adopted before the end of scheduled operation (2003), the plan to decommission the BN- 350 reactor has not yet been developed. 456 'On Decommissioning of the Reactor BN- 350 in the Aktau City of the Mangystau Region'. Taking into account technical, financial and political issues, the Government of Kazakhstan enacted the Decree no. It was commissioned in 1973 and intended for weapon-grade plutonium production and as stream supply to a water desalination facility and the turbines of the Mangyshlak Atomic Energy Complex. The experimental and commercial BN- 350 NPP equipped with a fast neutron sodium cooled reactor is located in Kazakhstan near the Aktau city on the Caspian Sea coast.
