Insights

Decommissioning Leadership Sellafield operates the UK’s largest restoration and decommissioning program and is the only site that safely manages all forms of nuclear waste. This creates demand for end-to-end program management, engineering services, regulatory compliance, and risk and safety analytics to deliver complex, mission-critical projects on schedule.

Cybersecurity Readiness Recent cybersecurity failings and penalties highlight a critical need for robust cybersecurity governance, incident response, and OT/ICS security for nuclear infrastructure. This presents opportunities to provide security assessments, managed security services, training, and regulatory/compliance programs tailored to the sector.

Simulation Training Funding for a digital and gaming hub signals appetite for digital twins, VR/AR training, and simulation-based safety programs to upskill staff and improve operational readiness across decommissioning and waste management activities.

Waste Management Tech Being the sole site capable of safely managing all nuclear waste and storing spent fuel creates demand for advanced waste treatment technologies, robotics and remote handling, containment monitoring, storage cask solutions, and data-driven waste characterization.

Strategic Partnerships Recognitions as a nuclear excellence center and active community engagement open doors for joint R&D, public-private partnerships, and regional procurement initiatives. This enables partnerships to supply specialized equipment, software, and services aligned with government-funded nuclear programs.
