If you wanted to design a use case where AR and VR deliver maximum value, nuclear energy would be a strong candidate. The environments are hazardous. Training opportunities on real equipment are limited. Inspections must be done quickly to minimise radiation dose. Procedures are complex, non-routine, and can’t be practised casually. And the cost of an error is catastrophic.

Which is why the nuclear sector has been quietly building out one of the more mature enterprise XR programmes of any industry, out of the public eye. It’s not glamorous in the way consumer AR is glamorous, but it’s real, funded, and delivering measurable results.

The Dose Reduction Case for AR

The dominant use case in nuclear operations is inspection with AR-assisted guidance. The core problem is ALARA: As Low As Reasonably Achievable. Every minute a worker spends in a high-radiation zone contributes to cumulative dose. If a worker can complete a maintenance or inspection task in 20 minutes instead of 60 because they have step-by-step AR guidance visible in their field of view rather than consulting a paper procedure document, that’s a meaningful dose reduction.

EDF Energy’s nuclear fleet in the UK has been trialling AR headset-based guided maintenance at multiple stations. Workers wear ruggedised AR headsets rated for industrial environments and receive step-by-step visual overlays on equipment components, with real-time video fed back to a remote expert who can annotate the worker’s view. The productivity gains are secondary to the dose reduction rationale, but they’re real too — first-time-right completion rates on maintenance tasks improve substantially when workers have visual confirmation of each step.

The challenge is headset certification. Nuclear plants are subject to the sort of electromagnetic interference considerations that mean consumer-grade devices don’t automatically qualify. Vendors including Honeywell, Daqri (before its closure), and more recently Trimble and RealWear have worked on nuclear-qualified AR hardware, but the certification process adds time and cost to deployment.

VR Training for Low-Frequency High-Stakes Procedures

Nuclear facilities deal with a particular training paradox: the most important procedures to practise are the ones that happen rarely or never. Emergency core cooling procedures, containment isolation, and loss-of-coolant accident response are critical — but you can’t practise them on live equipment, and simulator facilities are expensive to book and limited in availability.

VR simulation sidesteps this problem. A high-fidelity virtual replica of a reactor building, control room, or auxiliary system can be used for procedure practice as many times as needed, with variable scenarios including equipment failures, alarms, and radiation monitor readings that the instructor can control.

EDF’s Hinkley Point C has incorporated VR into its operator training programme from the construction phase — workers and eventual operators have been walking through virtual versions of the plant for years before the physical facility was complete. This is particularly valuable for familiarisation, building spatial memory of a complex multi-building site before setting foot in the real thing.

The fidelity requirements are high. If a valve is positioned incorrectly in the simulation, muscle memory built in VR could transfer to the physical environment as an error. Maintaining parity between digital twin and physical plant — especially during construction and commissioning when things change frequently — is a significant ongoing task.

Digital Twins for Plant Lifecycle Management

Beyond training, nuclear digital twins are becoming the backbone of plant lifecycle management. A comprehensive digital twin integrates as-built geometry, equipment data, maintenance history, and real-time sensor outputs into a navigable 3D model.

For inspection planning, this is transformative. Radiation surveys are overlaid on the digital twin, creating a dose-rate map that planners can walk through virtually before sending personnel in. Access routes, work station positioning, and equipment staging can be optimised in the model to minimise dose exposure before work begins.

Sellafield, responsible for one of the world’s largest nuclear decommissioning programmes, has invested heavily in digital twin technology. Areas of the site that are too contaminated for human inspection are modelled using robotic survey data, and the resulting digital twin allows remote planning of decommissioning operations without physical access.

Decommissioning Applications

Decommissioning is where XR may have the most long-term value in the nuclear sector. The UK alone has 17 nuclear sites in various stages of decommissioning under the Nuclear Decommissioning Authority. Decommissioning work involves dismantling structures that weren’t designed to be dismantled, in environments that may not have been physically entered for decades.

AR overlays that show historical building layouts (from archive drawings registered to the physical environment) help workers understand what’s behind walls and under floors before cutting or drilling. This is particularly important for avoiding unexpected contaminated material or sealed systems.

Remote inspection using robotics combined with XR visualisation is the emerging approach for areas that can’t be safely entered. A robot surveys the area, the data is processed into a navigable 3D model, and planners and engineers review it remotely in VR. This removes dose exposure from the planning phase entirely.

Current State and Constraints

The honest picture is that nuclear XR is mature in specific applications and immature in others. Guided maintenance with AR headsets is deployed at multiple UK and European stations and delivering results. VR operator training is widespread. Digital twin for inspection planning is operational at the leading sites.

What’s still limited is real-time sensor integration (radiation dose maps overlaid live into a headset view, rather than pre-planned), fully autonomous robotic inspection feeding live XR models, and consumer-grade AR hardware that meets nuclear qualification standards.

Hardware certification remains the primary constraint. RealWear’s HMT-1 and Navigator 500 are widely deployed in nuclear because they’ve gone through the qualification process and are designed for industrial environments. More capable headsets like the HoloLens 2 or Apple Vision Pro are used in planning and training contexts but aren’t qualified for use in controlled areas at most sites.

The economics are compelling, though. In nuclear, any technology that reduces dose exposure, prevents errors in high-consequence procedures, or shortens the time workers spend in hazardous environments pays for itself quickly. The sector is not a large market by unit volume, but it’s one where XR deployment makes clear and quantifiable sense.
