Bangladesh's Nuclear Leap: Powering Progress with Challenges

Economic Drivers:

1. Meeting Increasing Energy Demand: Bangladesh's rapid economic growth has led to a surge in electricity demand. The RNPP, with its projected 2.4 GWe capacity, aims to fulfill approximately 10% of the nation's electricity needs and address the expanding power deficit. The 2021 Power System Master Plan outlines Bangladesh's goal to achieve a 40 GWe capacity by 2030, with the RNPP being a crucial step toward this target.
2. Diversifying Energy Sources: Concerns about national energy security and environmental impact due to overreliance on natural gas prompt efforts to reduce its share to 52% by 2030, with an increase in nuclear power's contribution to 10%. The RNPP plays a pivotal role in achieving this objective, reducing vulnerability to global energy market fluctuations and supply disruptions.
3. Economic Growth and Development: The construction and operation of the RNPP are anticipated to generate employment, stimulate local businesses, and contribute to infrastructure development in the Pabna region

Strategic Considerations:

1. Energy Independence and Security: Diminishing reliance on imported fossil fuels enhances Bangladesh's energy independence, a critical aspect for a nation susceptible to climate change-related disasters.
2. Technological Advancement and Prestige: Nuclear power development symbolizes significant progress in science and technology for Bangladesh, aligning with its vision of becoming a knowledge-based economy and positioning itself as a regional leader in nuclear energy.
3. International Cooperation and Partnerships: Collaborating with Russia on the RNPP project facilitates the transfer of technical expertise and strengthens economic and diplomatic ties between the two nations.
4. Providing Reliable Baseload Power: While Bangladesh has plans for renewable energy, the intermittent nature poses challenges for consistent power supply. The RNPP, operating continuously, provides stable and reliable baseload power crucial for industries and essential services, complementing the contribution of renewable energy. According to the World Bank, Bangladesh's peak demand in 2021 was around 18 GWe, and the RNPP's contribution can significantly stabilize baseload and reduce reliance on peaking gas-fired power plants.

‍Reduced Carbon Footprint: Nuclear power offers a low-carbon energy source compared to fossil fuels, aligning with Bangladesh's efforts for climate change mitigation.

A significant portion, amounting to 90% of the projected cost of USD 12.65 billion for the project, is funded through a Russian government loan agreement executed in 2016. The interest rate on this loan is determined as LIBOR + 1.75%, with a maximum cap of 4%. Repayment is slated to commence ten years following the initiation of commercial operation of the first unit, originally planned for 2023 but now expected in 2024. The remaining 10% of the project expenditure is covered by the Bangladesh government.

Recent sanctions imposed on Russia by Western nations have introduced complexities in adhering to conventional channels for loan repayments. Consequently, both parties are exploring alternative payment methods, including the possibility of utilizing Chinese Yuan or establishing barter arrangements.

Additionally, the project encompasses fuel supply agreements with Rosatom, the Russian nuclear energy corporation. Post-commissioning, Bangladesh will bear the operational and maintenance costs of the plant. To ensure economic viability, the government aims to establish long-term electricity purchase agreements with either private or public entities for the Rooppur Nuclear Power Plant.

The original target of commissioning Unit 1 in July 2023 and Unit 2 in September 2024 is likely to be missed. Current estimates suggest Unit 1 may come online by December 2024, with Unit 2 potentially delayed further. Factors contributing to delays include complications in transmission line construction and logistical challenges with procuring materials. Rising global costs of materials and construction could inflate the project's overall budget so ensuring financial viability of the project is a concern.

Unit 1 Construction:

• Nearing completion with most major installations finalized.
• Hydraulic tests for Unit 1 successfully completed.
• First shipment of uranium fuel rods arrived in October 2023, marking a significant milestone.

Unit 2 Construction:

• Foundation work and reactor building construction are progressing.
• Installation of major equipment scheduled to begin soon.

Transmission Infrastructure:

• Progressing steadily, with some sections completed and others nearing completion.
• Initial phases of the crucial river-crossing lines are underway.

Addressing nuclear waste poses a global challenge, and the International Atomic Energy Agency (IAEA) plays a crucial role by offering guidance and fostering international collaboration to ensure the implementation of safe and sustainable waste management practices. The effectiveness and transparency in dealing with such wastes are paramount for gaining public trust and acceptance. To comprehend the nature of the wastes involved, it is essential to delineate the types:

• High-Level Waste (HLW): This category encompasses spent fuel rods containing fission products and transuranic elements, referring to heavy elements with half-lives exceeding 30 years. Characterized as the most radioactive waste, HLW necessitates long-term, deep geological disposal methods.
• Intermediate-Level Waste (ILW): Materials that have undergone irradiation, such as reactor components and tools with moderate radioactivity, fall under this classification. Typically, these materials are stored on-site in concrete vaults for several decades before being disposed of in near-surface facilities.
• Low-Level Waste (LLW): This category includes slightly contaminated items like clothing, tools, and filters. Generally, the management of LLW involves methods such as shallow land burial, incineration, or recycling, particularly for items like metal components..
  
  

Waste Management Strategies: 

Storage: The most common practice is on-site storage for spent fuel and other radioactive materials. This allows for decay of radioactivity before final disposal. Some countries are building centralized storage facilities.

Deep Geological Disposal: The preferred method for HLW disposal is burying it in stable underground rock formations, isolating it from the environment for millions of years. Several countries are exploring this option, but no permanent repositories are operational yet. While geological disposal is considered the most promising long-term solution for high-level nuclear waste (HLW), it's not without its challenges and concerns. Here are some key considerations:

• Finding suitable sites: Identifying geological formations with the necessary stability, isolation, and suitable geochemical properties for millions of years is a complex task. Extensive geological surveys and modeling are required.

‍

• Engineering and construction: Building a deep underground repository is a major engineering feat, requiring advanced technology and expertise in excavation, waste characterization, and containment systems.
• Long-term performance: Predicting the behavior of the repository and surrounding environment over millions of years presents both scientific and engineering challenges.

‍

• Potential for leaks or contamination: Although unlikely, there's a theoretical risk of radioactive materials escaping the repository through unforeseen geological processes or engineering failures, potentially impacting groundwater or the environment.

‍

• Transportation risks: Safely transporting HLW from power plants to the repository requires robust safety protocols and secure transportation infrastructure.

‍

• High initial costs: Building and operating a geological repository is a significant financial undertaking, requiring long-term funding commitments and cost management strategies.

Treatment and Disposal: Techniques like vitrification (encasing in glass) and transmutation (converting long-lived isotopes into shorter-lived ones) can reduce waste volume and radioactivity. Treated waste can then be disposed of in near-surface facilities or reused in some cases.

The Bangladesh Atomic Energy Regulatory Authority (BAERA) monitors and enforces safety regulations for all aspects of nuclear power generation and waste management at RNPP. Overall, the Rooppur Nuclear Power Plant has the potential to transform Bangladesh's energy landscape, providing clean, reliable power, and fostering economic and technological advancement. However, addressing technical, financial, and social aspects remains crucial to maximize its benefits and ensure long-term acceptance.
