<p>Arktis Radiation Detectors has reached a significant milestone in the advancement of its Waste Assay Neutron Detection System (WANDS). An active demonstration was successfully delivered in May this year, bringing the technology closer to potential deployment for nuclear waste characterisation.</p><p>With funding and support through Game Changers, WANDS has developed as an approach to addressing the <a href="https://www.gamechangers.technology/challenge/Condition_monitoring_and_inspection" rel="noopener noreferrer" target="_blank">challenge</a> of characterising legacy waste drums. WANDS has the potential to significantly improve how the amounts of fissile material within waste drums are measured, particularly in the case of dense or heavy metal alpha-contaminated wastes. By enabling more accurate waste classification, WANDS could allow more efficient waste handling and disposal, providing better options for Sellafield’s decommissioning mission.</p><h2>Addressing a Complex Waste Characterisation Challenge</h2><p>Sellafield manages thousands of legacy waste drums that require characterisation before they can be appropriately sentenced for disposal. Currently, waste drums must be transported within Sellafield site from their current location to a specialist facility for analysis – this is inherently labour intensive, time consuming, costly and potentially hazardous.</p><p>Existing drum analysis techniques are challenged when it comes to providing sufficient confidence in fissile material content when assessing dense or heavy metal alpha-contaminated wastes. This can result in waste being assigned a higher classification than necessary, increasing disposal costs.</p><p>WANDS has been specifically developed to solve this challenge. Using fast neutron detection technology based on Helium-4, the system is designed to improve the measurement of fissile material in challenging waste streams. The whole system is compact and fully mobile, around the size of a wheelbarrow. This would enable WANDS deployment at the site at which waste drums are currently stored, thereby negating the need to transport drums for assessment.</p><p><strong>WANDS has the potential to support the reclassification of some Plutonium Plant Decommissioning Wastes from Plutonium Containing Material (PCM) to Low Level Waste (LLW), with potential savings estimated in the region of £5–20 million.</strong></p><blockquote class="ql-align-center">Simon Malone, Measurement &amp; Analysis R&amp;D Lead at Sellafield, said:</blockquote><blockquote class="ql-align-center">“With our current methods, if we're not certain how a waste packages should be classified, we have to assign it to the higher classification category, which can cost around 10 times more. Technologies such as WANDS have the potential to improve confidence in waste characterisation and help us better distinguish between low level waste and plutonium-containing material. Greater confidence in classification could ultimately deliver savings of tens of millions of pounds.”</blockquote><h2>Active Demonstration Marks a Major Milestone</h2><p>In May, Arktis transported WANDS to the radiological facility operated by Mirion Technologies (UK) at Birchwood Park, where the system was integrated into an active interrogation setup.</p><p>The demonstration successfully tested the technology’s concept of operation and energy calibration in an active environment and was attended by representatives from Sellafield Ltd, AtkinsRéalis and AWE.</p><p><strong>Video available soon</strong></p><p>The demonstration represents another important step in evaluating the technology and understanding how it could support future waste characterisation activities. It also highlights the progress made through sustained collaboration between Arktis, Sellafield and the Game Changers programme.</p><blockquote class="ql-align-center">Ulisse Gendotti, CEO of Arktis Radiation Detectors Ltd, said:</blockquote><blockquote class="ql-align-center">“This demonstration represents an important step in the development of WANDS and shows the potential of our approach to improve the efficiency and accuracy of waste characterisation. The system has been designed to be deployed close to the point where waste is being stored, reducing the need to transport material for analysis. The support we've received through Game Changers has been fundamental in helping us develop the technology from an early concept to an actively demonstrated system, and we're looking forward to continuing its evaluation alongside future stakeholders.”</blockquote><h2>Continuing the Journey Towards Operational Validation</h2><p>Later this year, WANDS will undergo a further measurement campaign using radioactive sources transported from Sellafield to Mirion’s specialist facility. Successful completion of this work will see the technology achieve Technology Readiness Level 6 (TRL6), demonstrating that it has been actively tested in a relevant environment.</p><p>This milestone will conclude WANDS’ development journey through the Game Changers programme, following a sustained period of support from Sellafield’s Central Technical team and Game Changers.</p><p>The next stage will be to further validate the technology through operational trials. Alongside other emerging approaches to waste characterisation, WANDS could provide Sellafield with additional options for improving the assessment of challenging waste streams, ultimately, supporting efficient waste management and reducing costs.</p><p>Game Changers continues to support the development and demonstration of innovative technologies that address complex challenges across Sellafield and the wider nuclear sector, helping organisations evaluate new approaches and progress promising solutions towards future application.</p><p>WANDS now requires support from relevant facility stakeholders to help progress onsite validation and further explore the potential benefits of this technology.</p>

<p>A successful active demonstration of WANDS has marked a major milestone, showing how Game Changers support is helping advance mobile nuclear waste characterisation technology towards operational validation and potential future deployment.</p>

REACH web 1.png

<p>A significant step has been achieved in the development of REACH, an advanced remote access, characterisation and handling technology with the potential to address restricted-access challenges across Sellafield and the wider NDA estate, and with relevance to other industrial settings where access is restricted.</p><p>Developed by Eadon Consulting, REACH – Remote Extendable Access, Characterisation and Handling – was recently demonstrated to stakeholders from across the NDA estate at Eadon’s facility in Cockermouth. The demonstration showed how an initial challenge-led concept has progressed through Game Changers into a maturing engineered system capable of being remotely deployed, extended and articulated to reach spaces that are difficult, unsafe or impossible for people to enter directly.</p><p>The technology was originally developed in response to the challenge of <a href="https://www.gamechangers.technology/challenge/Post_Operational_Clean_Out" rel="noopener noreferrer" target="_blank">Post Operational Clean Out</a>, where limited access to complex, highly radioactive environments can restrict inspection, characterisation and data collection. As James Hill from Eadon Consulting explained, “REACH will enable remote data collection and sampling from locations it hasn’t been possible to access previously.” The system has been designed to help address this challenge by providing a flexible remote capability that can navigate constrained spaces, move through complex and off-axis geometries, and carry sensors or tooling to locations where direct access is not possible.</p><h2>Innovation in the Making</h2><p>The stakeholder demonstration represented the culmination of the second Proof of Concept phase and highlighted the significant progress made through Game Changers. Working closely with Sellafield stakeholders over a number of years, the project has moved through iterative design, build and testing phases, towards a more mature engineered system with potential for active deployment.</p><blockquote><span style="color: black;">“Without the Game Changers programme and FIS360 team working alongside us, this project would not have been as successful as it is. They have guided us through the process and pushed us to think about the next steps to commercialisation along the way,” said James Hill from Eadon Consulting.</span></blockquote><h2>Putting REACH Through its Paces</h2><p>During the demonstration, attendees saw the 110mm diameter carbon-fibre tube modules extend the system’s reach, while hinge and swivel modules enabled off-axis movement and rotation. The system is designed to carry payloads of up to 25kg over a span of up to 10m, supporting the deployment of interchangeable sensors and manipulator end-effectors for inspection, mapping, sampling, handling and data collection tasks.</p><p>Cockermouth-based robotics and sensors firm Createc supplied a mock N-VISAGE radiation sensor device, matched in size and weight to the operational tooling intended for a future active demonstration. This allowed the team to show how a representative payload could be carried and manoeuvred by REACH. The system’s Power over Ethernet capability was also demonstrated using a camera feed displayed live to the audience.</p><iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1210177445/"></iframe><h2>A Technology with Potential Across the NDA Estate</h2><p>The event brought together operations, engineering, characterisation, robotics, remediation and technology stakeholders to explore potential use cases and deployment requirements. Feedback captured during the demonstration will inform the next stage of development towards active use.</p><blockquote><span style="color: black;">Sellafield challenge owners said: “This kind of technology could have a really significant impact beyond just remediation. It's not just a solution for one area – across our business portfolios, we've all got challenges where we need to reach difficult-to-access locations. The ability to deploy sensors into those areas is a significant capability, and understanding what material we have is the first step to being able to effectively treat it.”</span></blockquote><h2>One Step Closer to Active Deployment</h2><p>Through Game Changers, REACH has progressed from Technology Readiness Level (TRL) 2 to TRL6, demonstrating the value of a structured innovation pathway that connects real nuclear sector challenges with specialist technology developers and end users. The project has advanced from early feasibility work into a demonstrable capability with the potential to reduce worker exposure, improve characterisation, support better decommissioning planning and reduce the need for bespoke access solutions.</p><p>The next planned stage is an active demonstration. Insights from the stakeholder event will be used to refine integration and deployment requirements, with potential for technology capability of this type to be applied more widely across Sellafield and the wider NDA estate where long reach, constrained access, off-axis navigation or remote characterisation and handling are required.</p>

OVA web 2.png

<p>Sellafield’s Special Nuclear Materials (SNM) portfolio, as part of its digital transformation strategy, is investigating methods to simplify and enhance training and engineering walkdowns using novel technologies such as VR/AR. Technologies of this type, including platforms such as StellarX, have strong potential to help operators rehearse key tasks in a risk-free digital twin before live execution. Members of the SNM team and other Sellafield stakeholders recently joined OVA Inc at Sellafield’s Engineering Centre of Excellence for a demonstration of StellarX, OVA’s AI-powered VR/MR platform.</p><p>The demonstration formed part of an ongoing Game Changers proof-of-concept project designed to test the potential of immersive training in high-hazard environments, improving operator readiness while reducing reliance on costly and risky physical training environments. The session introduced the StellarX platform and its application for complex operational training scenarios. The event brought together operational stakeholders, technical specialists, and training leads to explore how AI-enhanced VR can transform preparedness for a range of safety-critical tasks.</p><h2>Addressing the Challenge of High-Risk Training Environments</h2><p>Training for high-hazard operational tasks presents a consistent challenge across the nuclear industry. Whether dealing with glovebox operations or other controlled environments, organisations must balance the need for realism with strict safety requirements. Physical mock-ups are expensive to build and maintain, and even controlled settings can introduce unnecessary risk exposure during rehearsal of complex procedures.</p><p>As Chris Ballard, Senior Technical Manager at Sellafield, noted during the session, “It’s the application of VR that’s being done differently here. So for us this is absolute cutting edge technology, something that we need to bring in.” His comment reflected a broader organisational desire to modernise training approaches across a variety of technical and hazardous tasks.</p><p>The aim of the project was therefore to assess whether immersive VR could provide a safe, repeatable, and scalable method of preparing operators for complex operations across multiple domains, while maintaining procedural accuracy and confidence.</p><h2>Building a Flexible Digital Training Environment</h2><p>OVA’s platform, StellarX, was deployed to create realistic virtual training environments tailored to Sellafield’s operational requirements. The VR platform further enables creators to make immersive experiences with intuitive no-code tools, enabling training teams to build and modify scenarios without specialist programming skills.</p><p>This flexibility was central to the design approach. As OVA explained during development, “VR has a clear role to play in high-risk training environments, particularly where safety, procedural accuracy, and confidence are critical. It allows learners to practise complex procedures in a realistic but controlled environment before entering operational settings.”</p><p>The platform also supports guided interactive training and collaborative learning, allowing users to experience procedural workflows in structured yet adaptable environments. According to OVA, “immersive training can help modernise technical training by making it more engaging, repeatable, and accessible – learners experience real procedures rather than only reading about potential ones.”</p><h2>Demonstration at the Engineering Centre of Excellence</h2><p>The live demonstration combined a structured presentation with hands-on VR experience. Sellafield introduced the session before OVA walked attendees through the StellarX platform, highlighting scenario creation tools and demonstrating how training environments can be adapted quickly using no-code functionality across different operational use cases.</p><p>Attendees then used VR headsets to experience a simulated glovebox training scenario directly, while others observed the training flow on display screens. This dual setup allowed the wider group to assess user interaction, procedural realism, and training effectiveness in real time across multiple perspectives.</p><iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/1198897491/"></iframe><p>The response was overwhelmingly positive. As Paul Nichol, Director of SNM Portfolio at Sellafield Ltd, observed, “This technology brings to life the factory of the future. I’m so encouraged by what I’ve seen.”</p><h2>Outcomes and Validation from Stakeholders</h2><p>The project’s success was underpinned by close engagement with plant glovebox and training subject matter experts, whose input ensured that the virtual environments accurately reflected real procedures and constraints across the selected scenarios. Their involvement helped validate both the technical fidelity and practical relevance of the simulations.</p><p>The live demonstration at Sellafield’s Engineering Centre of Excellence proved pivotal in demonstrating value to stakeholders and end users. Observers were able to see not only the realism of the environment but also how quickly users adapted to the interface and training tasks, reinforcing confidence in its broader applicability.</p><h2>Benefits for Sellafield and the Wider Nuclear Sector</h2><p>The project highlighted a unique opportunity to visualise a facility that is not yet built or in operation, giving a new potential tool to enable pre-visualisation and operational process simulation across the portfolio for new and existing facilities. Immersive VR training enables safer rehearsal of hazardous tasks, reduces exposure to operational risk, and improves operator confidence before live execution. These benefits extend across multiple types of high-consequence procedures, not limited to any single operational area.</p><p>It also supports more efficient refinement of procedures, allowing teams to test and iterate training scenarios in a digital environment before deployment in real-world settings.</p><p>The no-code nature of StellarX further enhances its value by reducing reliance on specialist developers and enabling faster updates to training content. This creates potential for more responsive and continuously improving training systems across diverse operational environments.</p><h2>Scaling Impact and Future Direction</h2><p>The collaboration highlighted the value of structured innovation pathways. OVA noted that “without the Game Changers programme, we would have had a much harder time demonstrating the value we could bring to Sellafield,” adding that support from FIS360 helped “create the right conditions for a productive project by supporting introductions, facilitating meetings, and structuring the path forward.”</p><p>Looking ahead, the project has opened pathways for broader adoption of immersive training across Sellafield operations and potentially wider nuclear industry applications. Future work will explore how such technology can be scaled with additional scenarios, expanded across teams and sites, and integrated into longer-term digital training strategies.</p>

<p>Demonstrated live at Sellafield’s Engineering Centre of Excellence, OVA’s StellarX immersive VR platform showcased how realistic virtual environments could transform training, improve preparedness, and reduce risk across high-hazard nuclear operations.</p>
