Bilibino Nuclear Power Plant: Arctic Operations and Decommissioning

Overview

The Bilibino Nuclear Power Plant (Bilibino NPP) was a critical energy infrastructure asset located in the remote Chukotka Autonomous Okrug in the Russian Far East. Operational from 1974 until the final unit shutdown in December 2025, the facility served as the primary baseload power source for the region, supporting mining operations, transportation hubs, and the town of Bilibino. The plant consisted of four EGP-6 reactors, a specialized design developed by the Soviet Union to address the unique logistical challenges of Arctic energy production. With a total installed capacity of 144 MW, it held the distinction of being the northernmost operating nuclear power plant in the world for much of its service life, situated at approximately 68° North latitude.

The strategic importance of the Bilibino NPP extended beyond simple electricity generation; it was a cornerstone of Arctic energy security. The Chukotka region, characterized by permafrost, harsh winters, and limited road connectivity, relied heavily on the plant to stabilize the local grid. Prior to the full integration of the floating nuclear power station *Akademik Lomonosov*, the Bilibino NPP provided a continuous power supply that reduced the region's dependence on diesel generators and the volatile coal supply chain from the Kolyma basin. This reliability was essential for sustaining the aluminum smelting industry and gold mining sectors, which are energy-intensive and vital to the local economy.

Did you know: The EGP-6 reactors at Bilibino were unique in their design, utilizing a combination of natural circulation for coolant flow and graphite moderation, allowing for relative simplicity in maintenance compared to larger pressurized water reactors.

The decommissioning process, which began in March 2018 with the shutdown of the first unit, marks a significant transition in the energy landscape of the Russian Arctic. The final closure of the remaining three units in December 2025 completes the operational phase of the plant. The site is now entering a prolonged period of fuel removal and environmental rehabilitation. According to operator reports, all used nuclear fuel is scheduled to be removed by 2042, with full site rehabilitation expected to be completed by 2055. This timeline reflects the complexity of managing nuclear waste in a fragile permafrost environment, where thermal dynamics and geological stability are critical factors.

The replacement of the Bilibino NPP by the *Akademik Lomonosov* floating nuclear power station illustrates the evolving strategies for Arctic energy infrastructure. While the Bilibino plant was a fixed, land-based facility, the *Akademik Lomonosov* offers modular flexibility and reduced logistical burdens for fuel delivery. The transition underscores the ongoing need for reliable, low-carbon energy sources in the Russian North, where climate change and economic development pressures continue to shape energy policy. The legacy of the Bilibino NPP remains a key case study in the engineering and operational challenges of nuclear power in extreme environments.

History and Development

The decision to deploy nuclear power in the Chukotka Autonomous Okrug was driven by extreme geographical isolation and the limitations of conventional fossil fuels. Located in the far northeast of Russia, Bilibino is situated roughly 600 kilometers from the nearest major power grid. During the mid-20th century, the Soviet Union sought to consolidate its Arctic territory, relying heavily on coal, peat, and oil. However, transporting these fuels to the tundra was logistically expensive and vulnerable to seasonal disruptions. Nuclear energy offered a solution: a high energy-density fuel source that could be shipped in smaller volumes, primarily by air or via the seasonal Lena River route, to provide a stable baseload for the region’s mining operations and growing settlements.

Construction of the Bilibino Nuclear Power Plant began in the late 1960s, culminating in the commissioning of the first unit in 1974. The plant utilized four unique EGP-6 (Energetichesky Grebenchasty Reaktor, or "Energy Comb Reactor") units. Each reactor had a net capacity of approximately 36 MW, bringing the total installed capacity to 144 MW. This design was specifically engineered for the harsh Arctic conditions, featuring a compact layout and a once-through cooling system that drew water from the nearby Taimyrsky River. The plant became a critical infrastructure asset, not only for electricity generation but also for district heating, which was vital for keeping the town of Bilibino livable during the long, severe winters.

Background: The EGP-6 reactor was a specialized design that never saw widespread adoption elsewhere. Its unique "comb" structure allowed for efficient heat exchange in a compact footprint, making it ideal for the remote site, but also complicating the eventual decommissioning process due to the scarcity of spare parts and specialized engineering knowledge.

For over four decades, the plant operated with relative stability, though it faced ongoing challenges related to maintenance and the aging of infrastructure. The remote location meant that specialized technicians and heavy equipment had to be flown in or transported over long distances, increasing operational costs. Despite these challenges, Bilibino remained the second northernmost nuclear power plant in the world, playing a crucial role in the economic viability of the Chukotka region. The plant's output was fed into a 220 kV transmission line that stretched over 500 kilometers to the town of Pevek, linking several smaller settlements in a unique Arctic grid.

The decline of the plant began in the early 21st century as Russia sought to modernize its Arctic energy infrastructure. The decision to decommission Bilibino was influenced by the high costs of maintaining the aging EGP-6 reactors and the introduction of more flexible nuclear solutions. The floating nuclear power station Akademik Lomonosov was commissioned to replace Bilibino, offering a more modern and adaptable power source for the region. The first unit at Bilibino was officially shut down in March 2018, marking the beginning of a phased closure. The remaining three units continued to operate to ensure grid stability during the transition, with the final unit ceasing operations in December 2025. This final shutdown concluded an era of fixed-site nuclear power in the far northeast, with plans in place for the complete removal of used nuclear fuel by 2042 and full site rehabilitation by 2055.

Technical Specifications and Reactor Design

The Bilibino Nuclear Power Plant utilized four EGP-6 (Energeticheskaya Glavnaya 6) reactors, a specialized design developed by the Kurchatov Institute for remote, cold-climate operations. Unlike the more common Pressurized Water Reactors (PWR) or Boiling Water Reactors (BWR), the EGP-6 is a graphite-moderated, light-water-cooled reactor. This configuration allows for a relatively large core volume, which provides inherent thermal inertia—crucial for stability in the extreme temperatures of the Chukotka Autonomous Okrug.

Each of the four units had a net electrical capacity of approximately 36 MW, summing to a total plant output of 144 MW. This modest scale made Bilibino the smallest nuclear power plant in the world at the time of its final decommissioning. The reactors were housed in individual buildings, a design choice that simplified maintenance and allowed for sequential shutdowns, as seen when the first unit ceased operation in March 2018 and the final three in December 2025.

The fuel cycle relied on low-enriched uranium (LEU), typically enriched to around 2.4% U-235. The fuel assemblies were arranged in a hexagonal lattice within the graphite moderator blocks. This layout optimized neutron economy, allowing the reactors to operate efficiently even with the lower enrichment levels compared to modern PWRs. The use of uranium fuel is consistent with the plant's classification as a uranium-based nuclear facility.

Caveat: The EGP-6 design is distinct from the RBMK reactors used at Chernobyl. While both are graphite-moderated, the EGP-6 uses water as the primary coolant in a single-loop system, whereas RBMKs use a two-loop system with separate steam generators. This difference significantly impacts the thermal-hydraulic behavior and safety profile of the reactors.

Cooling was achieved through a direct cycle system. The primary coolant, light water, circulated through the core, absorbing heat generated by fission. This heated water then passed directly into the steam turbine generator set. After expanding through the turbine, the steam was condensed back into water and returned to the reactor. This direct cycle simplified the plant layout but meant that the turbine hall was slightly radioactive, requiring specific shielding and maintenance protocols.

The design of the EGP-6 reactors was optimized for reliability in remote locations. The graphite moderator provided significant thermal mass, allowing the reactors to withstand short-term fluctuations in heat removal. This was particularly important in Bilibino, where the ambient temperature could drop below -40°C, affecting the efficiency of the air-cooled condensers. The plant's ability to maintain stable operation under these conditions was a testament to the robustness of the EGP-6 design.

Maintenance of the reactors involved periodic replacement of fuel assemblies and inspection of the graphite core. The hexagonal arrangement of the fuel channels allowed for relatively easy access for control rods and instrumentation. The control system utilized boron carbide control rods, which were inserted into the graphite core to regulate the neutron flux and, consequently, the power output. This mechanical control system was simple and reliable, reducing the need for complex electronic controls that might be susceptible to failure in the harsh Arctic environment.

The decommissioning process for the EGP-6 reactors is expected to continue until 2055. This timeline accounts for the removal of used nuclear fuel, which is projected to be completed by 2042. The fuel will be transported to central storage facilities in Russia, a logistical challenge given the plant's remote location. The site rehabilitation will involve the dismantling of the reactor buildings and the treatment of the graphite moderator, which has become slightly radioactive over the decades of operation.

How did the EGP-6 reactor design suit the Arctic environment?

The EGP-6 reactor design was fundamentally shaped by the harsh realities of the Chukotka Autonomous Okrug. Located in one of the most remote regions on Earth, the Bilibino plant faced challenges that standard nuclear designs, such as the VVER or PWR, would struggle to manage without massive infrastructure investments. The engineering choices made for the EGP-6 were not merely incremental improvements but radical adaptations to ensure survival in the Arctic permafrost, extreme cold, and seismic activity. This approach prioritized reliability and maintainability over pure thermal efficiency, a necessary trade-off for a region where a single failure could mean months of darkness for thousands of residents.

Natural Circulation Cooling

The most distinctive feature of the EGP-6 (Energeticheskii Gidrolokalnyy, or "Energy Hydrolocal") reactor is its reliance on natural circulation for primary cooling. Unlike pressurized water reactors (PWRs) that depend on large electric pumps to drive coolant through the core, the EGP-6 utilizes the density difference between heated and cooled water. Hot water rises from the core through the steam generator and into the upper plenum, while cooler, denser water sinks back down through the downcomers. This design eliminates the need for massive, power-humping circulation pumps, which are prone to mechanical failure and require significant maintenance—both critical concerns in a remote Arctic setting.

This natural circulation mechanism provides inherent safety and operational simplicity. In the event of a power outage, the cooling loop continues to function as long as the temperature gradient is maintained. This passive safety feature is particularly valuable in Bilibino, where grid stability can be influenced by the very plant it supports. The design reduces the number of moving parts, thereby lowering the frequency of maintenance interventions. For a plant located thousands of kilometers from major industrial centers, minimizing the need for spare parts and specialized technicians is a significant operational advantage. The simplicity of the system allows for quicker diagnosis and repair, reducing downtime and ensuring a more consistent power supply to the local grid.

Caveat: While natural circulation offers reliability, it limits the thermal power output. The EGP-6's net capacity of approximately 36 MW per unit is modest compared to modern large-scale reactors, reflecting the design's focus on adaptability over sheer power generation.

Seismic Resilience and Structural Design

Seismic activity is a constant threat in the Chukotka region, where the interaction of tectonic plates creates frequent ground movements. The EGP-6 reactors were designed with significant seismic resilience in mind. The reactor building is constructed from reinforced concrete, providing a robust shield against external forces. The design incorporates flexible supports and dampening mechanisms to absorb and distribute seismic energy, reducing the stress on critical components such as the pressure vessel and steam generators. This structural integrity ensures that the reactor can withstand moderate earthquakes without compromising the integrity of the primary cooling loop or the containment structure.

The layout of the plant also contributes to its seismic resilience. The four EGP-6 units are housed in a single, large building, which allows for shared infrastructure and centralized control. This compact arrangement reduces the exposure of piping and cabling to external elements, minimizing the points of potential failure during ground movement. The design also includes redundant safety systems, such as emergency core cooling systems, which can be activated automatically in response to seismic sensors. These systems are designed to function even if the main power supply is interrupted, ensuring that the reactor core remains cooled and the fuel is protected from overheating.

Adaptation to Extreme Cold

Operating in an environment where temperatures can drop below -40°C requires specialized engineering solutions. The EGP-6 design incorporates extensive insulation and heating systems to protect critical components from freezing. The primary cooling loop is designed to maintain a stable temperature, preventing the coolant from becoming too viscous or forming ice crystals that could obstruct flow. The steam generators and turbines are also equipped with tracing heaters and insulated casings to maintain optimal operating temperatures. These measures ensure that the plant can start up quickly and operate efficiently even during the harshest winter months.

The plant's location on the permafrost also presents unique challenges. The foundation of the reactor building is designed to accommodate the seasonal thawing and freezing of the ground, which can cause significant shifts in the terrain. Pile foundations are used to anchor the structure deep into the permafrost, providing stability and reducing the risk of settlement. The design also includes drainage systems to manage meltwater and prevent the formation of ice lenses that could exert pressure on the foundation. These adaptations ensure that the plant remains stable and functional despite the dynamic nature of the Arctic landscape.

The EGP-6 design represents a thoughtful integration of nuclear technology and Arctic environmental conditions. By prioritizing natural circulation, seismic resilience, and cold-weather adaptations, the engineers created a reactor that could thrive in one of the most challenging environments on Earth. This design philosophy not only ensured the reliable operation of the Bilibino plant for over five decades but also provided valuable insights into the future of nuclear energy in remote regions. The success of the EGP-6 demonstrates that with the right engineering choices, nuclear power can be a viable and sustainable energy source even in the harshest climates.

Operational Challenges and Environmental Impact

Operating a nuclear facility at 68°N latitude introduced logistical complexities that defined the plant’s lifecycle. The remote location in the Chukotka Autonomous Okrug meant that standard supply chains were often insufficient, requiring a blend of maritime and aerial transport. Fresh uranium fuel and critical spare parts were frequently flown in by aircraft, a costly necessity given the seasonal freezing of the sea route to the nearby port of Pevek. This reliance on air freight significantly increased the operational expenditure compared to continental nuclear sites, a cost that was partially offset by the high price of thermal coal, which the plant was originally designed to compete with.

Fuel Logistics and Waste Management

The management of spent nuclear fuel presented a persistent challenge. Unlike larger plants that might ship fuel annually, Bilibino often stored used fuel on-site due to the high cost of transport. The plant utilized EGP-6 reactors, which were pressurized water reactors designed specifically for the harsh northern environment. The spent fuel was typically stored in cooling pools and later moved to dry cask storage. According to decommissioning plans, all used nuclear fuel is expected to be removed by 2042. This long timeline reflects the need to coordinate transport vessels during the short Arctic summer window when ice breakers can navigate the Kolyma River and the Laptev Sea. The delay in removing fuel increases the on-site criticality risk and the need for continuous monitoring, adding to the long-term liability of the site.

Caveat: The term "decommissioned" for Bilibino refers to the cessation of power generation. The physical dismantling and full site rehabilitation are projected to continue until 2055, meaning the site remains an active nuclear facility for several more decades.

Environmental monitoring in the tundra and permafrost required specialized protocols. The permafrost foundation demanded careful thermal management to prevent the ground from thawing, which could destabilize the reactor buildings. Engineers had to monitor the temperature of the ground beneath the plant to ensure that the heat from the reactors and the cooling systems did not create a "thermal halo" that would soften the permafrost. This required a network of thermometers and periodic drilling to measure the depth of the active layer. Any significant thawing could lead to subsidence, potentially affecting the alignment of the reactor vessels and the integrity of the containment structures.

The surrounding ecosystem, dominated by tundra vegetation and reindeer herds, was sensitive to both thermal and radiological discharges. The plant discharged cooling water into the Kolyma River, which was then released into the Laptev Sea. Monitoring stations tracked the temperature of the river to prevent thermal shock to the aquatic life. Radiological monitoring focused on the three main isotopes: Caesium-137, Strontium-90, and Iodine-137. These isotopes were measured in water, soil, and local flora, including the lichen that forms the base of the reindeer's diet. Reindeer herds were a particular concern because they could accumulate radioactive isotopes through the lichen-grass-reindeer chain, potentially exposing the local Evenki population to higher doses than the general population.

Despite these challenges, the plant was generally considered to have a relatively low environmental impact compared to the coal alternatives. The coal mines in the region were often open-pit operations that released significant amounts of sulfur dioxide and particulate matter. In contrast, the nuclear plant's emissions were primarily in the form of low-level liquid and gaseous discharges. The shutdown of the plant, completed in December 2025, was driven by economic factors and the availability of the floating nuclear power station Akademik Lomonosov. The transition to the floating station allows for a more centralized management of fuel and waste, potentially reducing the logistical burden on the remote Chukotka grid. The legacy of Bilibino remains a case study in the feasibility of nuclear power in extreme environments, highlighting the trade-offs between energy security and operational complexity.

Decommissioning Strategy and Timeline

The decommissioning of the Bilibino Nuclear Power Plant represents one of the most complex nuclear engineering challenges in the Arctic region. As the second northernmost nuclear facility in the world, its shutdown involves not only the standard cooling-down and dismantling of four EGP-6 reactors but also the logistical nightmare of removing spent fuel from a remote location in the Chukotka Autonomous Okrug. The process is strictly phased, spanning several decades to ensure radiological safety and environmental rehabilitation.

The operational lifecycle concluded with the sequential shutdown of its four units. The first reactor ceased operation in March 2018, initiating the cooling phase. The final three units were shut down in December 2025, marking the end of electricity generation for the plant. This staggered approach allowed operators to manage grid stability in the region, particularly with the integration of the floating nuclear power station *Akademik Lomonosov* as its successor.

Decommissioning Milestones

The removal of used nuclear fuel is the most critical intermediate phase. All spent fuel is scheduled to be removed by 2042. This involves transporting fuel assemblies from the on-site storage pools to the nearest reprocessing facility, likely in Siberia, via a combination of rail, road, and potentially sea transport. The harsh Arctic climate and limited infrastructure in Chukotka make this logistics chain particularly vulnerable to delays.

Caveat: The timeline for fuel removal is ambitious. Delays in transport infrastructure or changes in national nuclear policy could extend the 2042 target, potentially keeping the site in a "cold shutdown" state longer than initially planned.

Following fuel removal, the site will undergo full rehabilitation, targeted for completion by 2055. This phase includes the dismantling of the reactor buildings, the treatment of liquid and solid radioactive waste, and the restoration of the local tundra ecosystem. The EGP-6 reactors, which were graphite-moderated, water-cooled, and water-moderated, present unique challenges due to the activation of the graphite core over decades of operation. The graphite must be carefully extracted and classified as low- or intermediate-level waste.

The entire decommissioning effort is managed by Rosatom, which has integrated Bilibino into its broader strategy for managing legacy nuclear assets in Russia. The success of this project will serve as a benchmark for future Arctic nuclear decommissioning efforts, influencing how other remote facilities are managed in the coming decades.

What replaced Bilibino in the Chukotka energy mix?

The closure of the Bilibino Nuclear Power Plant did not result in a singular replacement but rather a strategic diversification of the Chukotka Autonomous Okrug’s energy infrastructure. As Bilibino’s four EGP-6 reactors were phased out—starting with Unit 1 in March 2018 and concluding with the final units in December 2025—the region shifted toward a hybrid model combining advanced floating nuclear technology and persistent diesel generation. This transition reflects the unique geographical and economic constraints of Russia’s most northeastern federal subject, where grid connectivity to the main European or Siberian systems remains limited.

The Akademik Lomonosov: A Floating Nuclear Solution

The primary nuclear successor to Bilibino is the Akademik Lomonosov, a floating nuclear power station (FNPS) moored in Pevek Bay, near the administrative center of Chukotka. Unlike Bilibino, which served a dispersed population across the tundra, the Akademik Lomonosov was designed to provide concentrated power to the port city of Pevek and the nearby nickel-copper mining operations of the Norilsk Nickel company. The vessel houses two KLT-40S pressurized water reactors, each with a net electrical capacity of approximately 35 MW, bringing the total output to around 70 MW. This capacity is slightly less than half of Bilibino’s original 144 MW total, indicating that nuclear power alone no longer dominates the regional mix as it did in the 1970s.

Background: The Akademik Lomonosov represents a significant technological shift from Bilibino’s land-based EGP-6 reactors. While Bilibino utilized graphite-moderated, pressurized water reactors similar in design to the RBMK series but smaller in scale, the Akademik Lomonosov employs KLT-40S reactors, which are essentially scaled-down versions of the VVER-1000 design used in many Russian mainland plants. This change simplifies fuel logistics and enhances safety through passive cooling systems, a critical feature for an Arctic environment.

The Akademik Lomonosov began commercial operation in 2019, providing a stable baseload power source that reduces reliance on volatile diesel prices. Its floating nature allows for potential mobility, although it is currently anchored to serve the Pevek region. The station also provides district heating, a crucial benefit in an Arctic climate where thermal energy demand is nearly as high as electrical demand. By replacing some of the diesel generation in Pevek, the FNPS has significantly lowered carbon emissions in the immediate vicinity, although its overall impact on the entire autonomous okrug is limited by its location.

The Persistent Role of Diesel Generation

While the Akademik Lomonosov serves Pevek, much of the rest of Chukotka continues to rely heavily on diesel-fired power plants. Bilibino’s closure left several remote settlements, including Anadyr, Uelen, and Lavrentiya, without direct nuclear power. These communities operate smaller, often aging diesel generators that supply electricity through local mini-grids. The diesel dependency is driven by the logistical challenges of transporting fuel to the far north, primarily via the summer sea route or air freight during the winter ice season.

The energy mix in Chukotka is therefore fragmented. Pevek benefits from nuclear stability, while other towns face higher energy costs and greater carbon footprints due to diesel use. This disparity has prompted discussions about further grid extensions or additional small modular reactors (SMRs) to serve more remote areas. However, as of 2026, no new land-based nuclear plants have been commissioned to replace Bilibino’s broader regional coverage. The diesel plants remain critical for energy security, providing redundancy and flexibility that the single floating station cannot fully offer across the vast, sparsely populated territory.

The transition from Bilibino to the Akademik Lomonosov and diesel hybrids illustrates a pragmatic approach to Arctic energy. It balances the high capital cost and technological complexity of nuclear power with the operational flexibility of diesel. This model ensures that while nuclear energy remains a cornerstone of Chukotka’s power supply, it is no longer the sole provider, allowing for a more resilient, albeit more complex, energy infrastructure. The full rehabilitation of the Bilibino site, expected to be completed by 2055, will further solidify this new energy landscape, removing the legacy of the EGP-6 reactors while the Akademik Lomonosov continues to power the region’s economic hub.

Legacy and Lessons for Arctic Nuclear Energy

The operational history of the Bilibino Nuclear Power Plant provides a critical case study for the deployment of nuclear energy in extreme Arctic environments. As the northernmost nuclear facility in the world, its design and operation addressed unique challenges related to permafrost stability, extreme cold, and logistical isolation. The plant utilized four EGP-6 reactors, a specialized design featuring natural circulation for cooling, which reduced reliance on mechanical pumps compared to standard Pressurized Water Reactors (PWRs). This technology choice was driven by the need for reliability in a region where grid stability was historically fragile.

Technological Adaptations for the Arctic

The EGP-6 reactor design incorporated features specifically tailored to the Chukotka Autonomous Okrug’s harsh climate. The natural circulation cooling system allowed the reactors to maintain heat removal even during power outages, a crucial safety feature for remote locations. Additionally, the plant’s layout and infrastructure were engineered to withstand temperatures dropping below -40°C and significant snow loads. The decommissioning process itself has become a technological benchmark, requiring the removal of used nuclear fuel and site rehabilitation under conditions that challenge standard construction and logistics. The timeline for full site rehabilitation, projected to extend to 2055, highlights the long-term commitment required for Arctic nuclear projects.

The decision to replace Bilibino with the floating nuclear power station Akademik Lomonosov reflects a strategic shift in how Russia approaches Arctic energy infrastructure. The floating station offers modularity and the ability to be towed to different locations, potentially reducing the fixed infrastructure costs associated with land-based plants. However, this transition also introduces new engineering challenges, such as maintaining structural integrity against ice pressure and managing brine discharge in a sensitive marine ecosystem. The comparison between the fixed Bilibino plant and the floating Lomonosov station provides valuable insights into the trade-offs between stability and flexibility in Arctic nuclear deployment.

Caveat: While floating nuclear power stations offer logistical advantages, their long-term operational data in the Arctic is still accumulating. Bilibino’s multi-decade operation provides a more extensive dataset for understanding the durability of nuclear infrastructure in extreme cold.

Environmental and Logistical Considerations

Environmental management at Bilibino involved addressing the unique challenges of waste disposal in a permafrost-dominated landscape. The plant’s operations required careful monitoring of thermal pollution and the potential impact on local wildlife, including migratory caribou and marine species. The decommissioning process has emphasized the need for robust waste management strategies, including the temporary storage of spent fuel and the eventual transport of waste to centralized repositories. The logistical complexity of moving materials to and from Bilibino, often relying on air and sea routes, underscores the importance of supply chain resilience in remote nuclear projects.

The lessons from Bilibino also extend to workforce management and local community engagement. Operating a nuclear plant in such a remote location required specialized training for staff and the development of support infrastructure for both workers and the local population. The plant contributed to the economic stability of the Chukotka region, providing jobs and energy security. As the region transitions to new energy sources, maintaining this economic and social stability remains a key consideration for future projects.

Future Arctic nuclear projects will likely draw on the technical and operational experiences gained at Bilibino. The emphasis on natural circulation cooling, robust structural design, and comprehensive environmental monitoring provides a template for new builds. However, the evolving climate conditions in the Arctic, including the thawing of permafrost and changes in ice cover, will require ongoing adaptation of these strategies. The decommissioning of Bilibino serves as a reminder that the lifecycle of a nuclear plant extends well beyond its operational phase, necessitating long-term planning for fuel management and site rehabilitation.
