Approval for American Companies to Build Nuclear Reactors in India

Why in News? 

Nuclear Reactors in India: Recently, the United States granted Holtec International permission to design and build nuclear reactors in India. This approval was given under U.S. regulations, paving the way for expanding commercial opportunities under the India-U.S. Civil Nuclear Agreement.

Key Points of the Approval of Build Nuclear Reactors in India 

• Holtec International has received approval from the U.S. Department of Energy (DOE) to design and build nuclear reactors in India.
• The company has been granted permission under the 10CFR810 regulation to transfer declassified Small Modular Reactor (SMR) technology to three private Indian companies.
• This approval is valid for 10 years, with a review every 5 years.
• The technology will be used by companies like Holtec Asia, Tata Consulting Engineers, and Larsen & Toubro.
• The technology and information will only be used for peaceful nuclear activities, under the security measures of the International Atomic Energy Agency (IAEA).
• There will be no access to enrichment technology or sensitive nuclear technology.
• The transfer of this technology to any other country or entity is prohibited without U.S. approval.
• Holtec will be required to send quarterly reports to the Department of Energy (DOE).

Why is this Agreement Important for India?

• Technological Advancement and Global Competitiveness: This deal is important for India as it allows for significant progress in the field of Small Modular Reactors (SMRs). India’s current nuclear program, based mainly on Pressurised Heavy Water Reactors (PHWRs), lags behind global standards.
• Private Sector Participation and Domestic Production: The deal boosts the role of the private sector in India, with companies like Holtec, Larsen & Toubro, and Tata Consulting Engineers involved. This collaboration will strengthen India’s domestic manufacturing capabilities for SMR components, moving the country toward self-reliance and increasing local production.
• Energy Security and Independence: This agreement will help India achieve its energy security goals. The construction of SMRs will provide an alternative energy source and increase the stability of energy supply, particularly as the demand for clean energy grows.
• Expansion of India-U.S. Nuclear Cooperation: This deal strengthens the India-U.S. nuclear relationship, following the 123 Agreement of 2007. The deal enables India to collaborate with U.S. companies on advanced reactor designs and equipment, enhancing the strategic partnership between the two nations.

What are Small Modular Reactors (SMRs)?

• • Small Modular Reactors (SMRs) are modern nuclear reactors designed to enhance safety and efficiency.
  • Their power generation capacity typically ranges from less than 30 MWe to 300 MWe.
  • The main objective is to provide small, safe, and cost-effective nuclear energy, which can be deployed at various locations.
  • Globally, over 80 SMR designs are in development or licensing stages, with some already operational.
• Key Features
  • SMRs are smaller than conventional nuclear reactors, making them easier to deploy at different locations.
  • They are designed to be modular, allowing for pre-assembly in factories, making transportation and installation simpler.
  • SMRs use nuclear fission to generate heat for electricity production.
• Types of SMRs
  • Land-based Water-Cooled SMRs: These include Pressurised Water Reactors (PWRs), using mature and established technologies.
  • Marine-based Water-Cooled SMRs: Designed for use in marine environments, such as floating reactors on barges or ships.
  • High-Temperature Gas-Cooled SMRs (HTGRs): These reactors can generate heat above 750°C, making them effective for electricity generation and industrial use.
  • Liquid Metal-Cooled Fast Neutron Spectrum SMRs (LMFRs): These reactors use sodium and lead as coolants, allowing them to operate at high temperatures.
  • Molten Salt Reactor SMRs (MSRs): These reactors use molten salts as coolants, allowing for long fuel cycles and online refuelling.
  • Microreactors (MRs): Extremely small SMRs, generating up to 10 MWe of electrical power.

Key Features of Holtec International’s Advanced SMR-300

• The SMR-300 is an advanced Pressurised Light-Water Reactor (PLWR), using low-enriched uranium fuel to generate electricity through nuclear fission.
• It provides at least 300 MWe of electric power, making it an effective and reliable solution for energy production.
• The compact design of SMR-300 requires much less land compared to traditional reactors, making it suitable for sites where space is limited, such as existing coal plants in India.
• The SMR-300 offers a clean energy alternative to fossil fuels like coal and gas, making it a key option for meeting India’s growing energy needs, particularly in sectors like Artificial Intelligence and data centers.
• It provides technological and economic benefits, being a cost-effective and environmentally friendly solution for meeting increasing energy demands.

Importance of Small Modular Reactors (SMRs) in India’s Nuclear Future

• Power Generation Capacity: SMRs can be scaled up or down based on energy needs. This flexibility can help solve India’s growing energy crisis. SMRs can be integrated with existing thermal power stations or used to rebuild old stations as zero-emission fuel.
• Lower Fuel Requirement: SMRs can operate for longer periods without needing fuel refills. While traditional power plants require fuel replacement every 1 to 2 years, SMR-based plants can go for 3 to 7 years before needing a refuel. This reduces India’s dependence on fuel supply, enhancing energy security.
• Automatic Safety Features: SMRs have passive safety features that use physics to shut down and cool the reactor without electricity or human intervention. This could address safety concerns with large reactors in India.
• Economic and Environmental Benefits: The cost of installing SMRs is lower compared to traditional large reactors. Additionally, they are more cost-effective in terms of operation and maintenance, making them an attractive option for energy production. SMRs could help meet India’s growing energy demands while addressing environmental challenges.

Challenges Related to SMR Construction in India

• Legal Barriers: The Civil Nuclear Liability Act (2010) and Atomic Energy Act (1962) create obstacles for foreign investors. These laws make it difficult for foreign companies to invest in India’s nuclear energy sector due to the legal provisions on risk and liability. Furthermore, nuclear energy production is limited to government entities, restricting private companies’ involvement.
• Regulatory Challenges: There are various technical and regulatory challenges in implementing SMR technology. Different SMR designs require different rules and standards, which makes large-scale implementation difficult. India’s current nuclear infrastructure, primarily based on heavy water reactors and natural uranium, does not align with the light water reactors (LWRs) commonly used worldwide. This requires developing new technical expertise and capacity.
• Waste Management: SMRs produce radioactive waste, which needs safe disposal and storage. Suitable facilities are required for proper waste management, but India’s infrastructure for waste disposal is not fully developed, leading to potential social and political resistance.
• External Costs: SMR construction, operation, and disposal come with high external costs. These costs are not only related to technical and safety measures but also to waste disposal, reducing environmental impacts, and proper maintenance. These challenges make SMR projects more economically difficult.
