Condition monitoring in the nuclear industry

The UK nuclear industry demands the highest levels of reliability, safety, and operational efficiency. With long asset lifecycles and stringent regulatory oversight, unplanned downtime or equipment failure can have significant implications, not only for productivity and cost, but also for safety and compliance.

Implementing condition monitoring and predictive maintenance strategies allows nuclear operators to detect early signs of degradation, optimise maintenance schedules, and extend the life of critical assets, all while maintaining the highest safety standards.

The importance of condition monitoring in the nuclear sector

Condition monitoring plays a vital role in improving efficiency and reliability across both operating and decommissioning sites. The nuclear environment presents unique challenges, including radiation exposure, restricted access zones, and long-running plant operation, all of which make non-intrusive monitoring solutions particularly valuable.

Unexpected downtime in nuclear facilities can lead to:

  • Disruption to generation schedules 
  • Increased safety and compliance costs 
  • Operational inefficiencies and unplanned maintenance interventions

By applying continuous condition monitoring, maintenance teams gain a clear, data-driven understanding of asset health, allowing them to plan interventions based on actual condition rather than fixed intervals. This approach reduces unnecessary maintenance, increases equipment availability, and enhances the overall efficiency of plant operations.

Typical applications in the nuclear sector

Faraday Predictive’s Model-Based Voltage and Current (MBVI) technology enables non-invasive condition monitoring of electrical and rotating equipment, ideal for nuclear environments where physical access to equipment can be limited or hazardous.

Typical applications include:

  • Reactor cooling pumps and fans – critical to reactor safety and performance; early fault detection ensures reliability.
  • Feedwater and condensate pumps – identifying mechanical or electrical degradation before it affects efficiency. 
  • Air handling and ventilation systems – essential for maintaining clean and safe operational environments.
  • Turbine and generator systems – monitoring for imbalance, insulation issues, or bearing wear to maximise uptime.
  • Decommissioning equipment and remote-handling systems – ensuring continued reliability of critical support assets.

Advantages of Faraday Predictive systems for nuclear applications

Non-intrusive installation –

MBVI systems are installed in the electrical switchgear, meaning no sensors are placed in controlled or hazardous areas.

Supports life extension –

helps operators manage ageing assets more effectively and justify extended operational life.

Enhanced safety compliance –

reduces the need for physical access to radiological zones or confined spaces.

Cost-efficient –

eliminates expensive sensor cabling and minimises installation downtime.

Continuous 24/7 monitoring –

provides real-time visibility of asset condition without the need for manual inspection.

Supporting a reliable, efficient nuclear future

As the UK nuclear industry focuses on lifetime extension, safe operation, and sustainable performance, predictive condition monitoring plays a critical role in achieving these objectives.

Faraday Predictive helps operators:

  • Increase plant efficiency and equipment uptime 
  • Improve maintenance planning and asset reliability 
  • Reduce maintenance costs and safety risks 
  • Gain valuable insights into asset health and operational performance

By combining non-intrusive technology with advanced data analytics, Faraday Predictive provides a future-ready solution that supports the UK’s transition to a more efficient, reliable, and low-carbon energy system.
