The global nuclear sector is entering a new phase of growth, fuelled by the rising need for reliable base-load power to support AI infrastructure, data centres, and national decarbonisation goals.
Among the many technologies enabling safe and efficient operation, one stands out for its enduring reliability — the mosaic control system. For decades, mosaic panels have formed the backbone of operator interfaces in nuclear control rooms, valued for their modularity, clarity, and lifespan of over 30 years.
Yet this critical technology now faces a supply chain challenge. Expertise in mosaic systems has long been concentrated among a handful of established European manufacturers. As ownership structures shift and investment in legacy support declines, nuclear operators are increasingly concerned about long-term availability of spare parts and qualified service.
At the same time, global demand for new nuclear capacity is rising sharply — placing pressure on a supply chain already stretched thin.
To ensure the continuity and safety of mosaic technology, diversification and innovation are vital. New manufacturers — particularly in emerging engineering economies — are filling the gap with modern production techniques, robust QA systems, and internationally recognised seismic and nuclear certifications.
India’s Werner Elektrik is one such example, producing high-quality mosaic systems that meet stringent European standards while offering enhanced manufacturing flexibility and cost efficiency. As the global energy landscape becomes increasingly interconnected, the challenge is no longer technical capability but building trust through transparency, qualification, and long-term partnerships.
The future of mosaic systems depends on how the industry embraces collaboration, open standards, and shared quality benchmarks. By doing so, we can safeguard this proven, safety-critical technology and ensure it continues to support the next generation of nuclear power plants worldwide.
