Upgrading Radiological Surveillance Systems in Nuclear Facilities
Omniflex upgrades faulty MPAS 90 alarms at a major cereal manufacturing facility in North Wales
The Obsolescence Challenge
Many nuclear facilities are now expected to operate for 80 to 100 years, but the control and monitoring systems installed decades ago were never designed with such longevity in mind. As legacy distributed control systems (DCSs) become obsolete, operators face the challenge of modernising critical radiation monitoring capabilities without introducing unnecessary risk, cost or disruption.
Why System Separation Matters
Industry best practice now recognises the importance of separating radiological surveillance systems (RSSs) from process control systems. Independent RSS platforms ensure radiation monitoring, alarms and evacuation functions remain operational regardless of issues elsewhere in the control architecture, improving both safety and resilience.
Modernisation Without Disruption
For over 30 years, Omniflex has helped UK nuclear sites modernise their monitoring infrastructure by enabling existing radiation detectors, cabling and field equipment to remain in service. This approach reduces project complexity, minimises disruption in radiation-controlled areas and provides a flexible, future-ready platform that can continue evolving alongside the facility for decades to come.
