Risk Management for the Nuclear and Energy Sectors
Much of the UK’s nuclear and energy infrastructure is approaching or has exceeded its original design life, reflecting an era of significant investment several decades ago.
Nuclear power stations, conventional thermal plants, transmission assets and supporting civil infrastructure are subject to long‑term degradation mechanisms such as material ageing, corrosion, fatigue, radiation effects, concrete deterioration and obsolescence of systems and components. These ageing processes are compounded by increasingly demanding operating conditions, tighter regulatory requirements and heightened expectations around safety, security and environmental performance.
As a result, asset owners face growing technical and operational challenges in ensuring that critical infrastructure continues to operate safely, reliably and in compliance with strict regulatory frameworks.
In this context, maintaining, optimising and extending the useful life of existing nuclear and energy assets has become a strategic priority for the UK. Life‑extension programmes, condition‑based maintenance and data‑driven asset management offer cost‑effective alternatives to premature decommissioning or large‑scale replacement, while supporting energy security and the transition to a low‑carbon energy system.
By investing in enhanced inspection, monitoring, modelling and predictive assessment, operators can better understand asset condition, anticipate degradation, and target interventions where they deliver the greatest benefit. This proactive approach not only reduces unplanned outages and safety risks, but also maximises return on historic investment and ensures that vital energy infrastructure remains resilient and fit for purpose well into the future.
Precision, Safety, and Assurance for the Nuclear Industry
At Sixense Limited, we deliver specialist monitoring, engineering, and digital asset management solutions to support the safe design, construction, operation, extended lifecycle and eventual decommissioning of nuclear facilities.
Working in one of the world’s most demanding and regulated industries, we provide the data, insight, and control needed to manage complex risks and maintain the highest standards of safety and reliability. Our expertise covers new build programmes, existing plant monitoring, waste storage facilities, and decommissioning projects across the UK.
Advanced Monitoring and Engineering Expertise
Sixense provides high-precision structural and environmental monitoring systems designed for the unique requirements of nuclear sites. Our technologies measure ground movement, vibration, settlement, strain, and temperature — delivering real-time data that supports safety-critical decisions and regulatory compliance.
We design and operate bespoke instrumentation systems for sensitive environments, including radiologically controlled areas, where accuracy, traceability, and reliability are paramount.
Coupled with our structural and geotechnical engineering expertise, we help clients mitigate risks, validate design performance, and protect both people and assets.
Environmental Noise Management in the energy sector
Our acoustic modelling and measurement services provide operators in the nuclear and energy sectors with a robust, evidence‑based understanding of sound and vibration environments within and around sensitive facilities. Using software compliant with ISO 9613 and incorporating site‑specific meteorological data, we deliver realistic assessments of noise propagation from plant, equipment and operational activities. These insights support environmental impact assessments, safety case development and regulatory compliance for both new‑build projects and operational assets, where control of environmental and occupational noise is critical to maintaining safe, licensable operations.
We design and advise on proportionate mitigation and monitoring solutions aligned to CAPEX and OPEX constraints, operational requirements and production continuity. Our extensive equipment fleet enables rapid deployment and sustained monitoring campaigns, with all instrumentation meeting the highest accuracy and calibration standards required in regulated energy environments. Supported by specialist expertise in environmental acoustics, internal noise mapping and occupational noise and vibration risk reduction, our services are delivered exclusively by HSE‑certified personnel, ensuring that all work is undertaken to the highest safety and quality standards demanded by the nuclear and wider energy sectors.
Digital Asset Management and Lifecycle Support
Beyond construction and commissioning, Sixense supports nuclear operators through digital inspection, asset intelligence, and long-term structural health monitoring. Using 3D laser scanning, photogrammetry, and digital twin technology, we capture and visualise detailed data on the condition of concrete structures, containment systems, and underground assets. Our data-driven approach enhances maintenance planning, improves traceability, and extends asset life while supporting full regulatory compliance. With Sixense as your partner, your nuclear infrastructure benefits from proven technical assurance, innovation, and an unwavering commitment to safety at every stage of its lifecycle.
