Small reactors, big impact: why Small Modular Reactors are becoming essential in the energy transition

More energy security and affordable prices

Belgium is densely populated. Space for wind and solar farms is limited. Small Modular Reactors offer an intriguing addition to the energy mix: they take up less space, produce less nuclear waste per unit of energy, are modularly deployable and can respond flexibly to fluctuations in supply and demand.

For industry and energy-intensive sectors, this means stable, low-CO₂ electricity at predictable prices, even on cloudy or windless days. This technology helps keep energy costs under control and ensures supply, which is crucial for our competitive position.

How SMRs fit into the bigger picture

Small Modular Reactors perfectly complement renewable sources. We see them as part of a symbiotic energy system. They contribute to grid stability by acting as ‘always-on’ base load power or by stepping in during peaks.

We’re also not just talking about a single technology, but a family of solutions. Some designs provide high-temperature steam for industrial processes; others are suitable for hydrogen production or decentralised energy supply. This versatility makes SMRs valuable for diverse needs: industries requiring guaranteed process heat, data centres demanding maximum continuity, or projects in remote locations that are not easily connected to the grid.

Thinking about permits and pilot projects now

At the system level, studies show that the smart deployment of Small Modular Reactors can reduce the total costs of the transition, provided that siting, technology choice and regulation are well planned. Construction and permitting processes take time. Starting early with pilot projects, feasibility studies, and supply chain development is essential for SMRs to effectively contribute to Belgium’s climate goals by 2030-2040.

That’s why we need to think now about permits and what space can be reserved for building such plants. This could be existing nuclear sites or industrial clusters in port areas. The chemical industry needs not only electricity but also heat that can be directly sourced from nuclear energy.

Belgium is already taking steps towards market-ready solutions, with a goal of possibly starting pilot projects by 2030, which offers a concrete window of opportunity.

From site analysis to Balance of Plant

We bring a practical and balanced approach, combining a strong local presence with an international network of nuclear expertise. While technology is often delivered by Original Equipment Manufacturers (OEMs) as a black box, we are ready to design and manage the boundary conditions: from site research, permits and environmental impact studies to civil and utility infrastructure and the engineering of the Balance of Plant (BoP). We guide you through feasibility studies and pre-licensing to construction and operational preparation, including supply chain assessments and collaboration with SMR developers.

For the Balance of Plant engineering, we specifically assist you with:

• Government consultations and permitting processes
• SMR technology selection
• Site and case feasibility
• Joint venture structure
• Pre-licensing agreements
• Supply chain assessments
• Basic and detailed design
• Construction licence
• Supply chain qualification
• Operating licence
• Preparation for construction, operation and maintenance

Local anchoring, global nuclear expertise

Our strength lies in experience and collaboration. We have global nuclear expertise in-house, including from Finland. At the same time, we provide local advice that takes into account the unique Belgian context: limited space, a dense network of stakeholders, and the need for integration with existing industry and grid structures. In short, we’re small enough to care and big enough to cope.

We think along with you about technology choice, joint venture structures and the gradual scaling of projects so that cost efficiency and permitting processes go hand in hand.

Ready for the next step in energy security

Small Modular Reactors are not a magic bullet, but in combination with renewable energy, smart grids and industrial flexibility, they form a strong lever towards climate neutrality. Those who prepare today avoid delays tomorrow and gain time, certainty and efficiency. Are you a technology provider, project developer or policymaker? Our experts will accompany you on the journey: we work together on a scalable, safe and future-oriented deployment of nuclear technology.
