Transition from operation to decommissioning of NPP units in the Russian Federation on the example of units 1 and 2 Leningrad NPP
1. Introduction
In Russian Federation in operation -11 NPPs (36 power units), Total - 30.5 GW. NPP produced over 20% of all power generated in Russian Federation. At 2022 – 9 power units are shut down for decommissioning, of which: 2 NPP – at decommissioning stage (decommissioning license granted); 7 NPP– at decommissioning preparation stage. By 2032, 17 power units are to be shut down for decommissioning.
2. Regulatory Framework
• Federal Law on the Use of Atomic Energy No. 170-FZ (∑ ~ 16 Federal laws and decrees)
• Safety Rules for Decommissioning of a Nuclear Power Plant Unit, NP-012-16 (∑ ~ 19 Codes/ Rules and Safety Guidelines)
• “Rosatom” Concept of Nuclear Facilities Decommissioning
• “Rosenergoatom” Concept of Power Units Decommissioning
• Leningrad NPP Concept of Power Units Decommissioning
• Programs of Leningrad NPP Power Units Decommissioning (individually for each Unit)
3. DECOM Preparation Stage
Rationale for “immediate dismantling” selection:
• Lower costs
• Higher radiation and technical safety
• Possibility for the NPP workforce retention
4. Prospects
• Development, try-out, implementation and improvement of new technologies for uranium-graphite reactors decommissioning;
• Extension to other NPPs;
• Personnel training in new technologies and techniques;
• RW interim storage and processing;
• Waste decontamination, fragmentation and conditioning facility.
