Due to the presence of debris, welds and protrusions, this is likely to be narrower than 25mm at points throughout, with an expected minimum of 20mm.

Internal inspection of long and narrow pipework

Routine visual inspection of existing assets across the Sellafield site is important to understand their condition, identify any defects, and manage the risk of failure. Internal inspection of narrow pipework can be particularly challenging due to bends, corrosion debris, lack of lighting, and the length of pipes.One example of such pipework is an overflow drain line that services the Sellafield Sealines. This drain line must be inspected every 2 years to ensure there is no damage or blockage. A solution is required that can provide live HD colour video of over 40m of pipework with an internal diameter of 20mm, navigating grit/sand, protruding circumferential welds and multiple bends.

Sellafield Ltd is seeking a technology capable of conducting internal visual inspection of long, narrow, convoluted pipework, providing live HD colour video to assess condition, identify any defects, and manage the risk of failure.

Non-intrusive characterisation of legacy waste drum contents

In preparation for the long-term disposal of legacy waste on the Sellafield site in a Geological Disposal Facility&nbsp;(GDF), waste package contents must be processed into a suitable safe and passive form. To process and treat the waste in the most safe, efficient and cost-effective way, Sellafield Ltd needs to fully understand the chemical, physical, radiological and fissile nature of the waste within the legacy packages.This challenge is focused on waste packages that contain untreated and unprocessed Plutonium Contaminated Material (PCM). Key to this challenge is the ability to obtain the required characterisation without opening or disturbing the contents of the PCM drums.

Sellafield Ltd is seeking methods to characterise legacy waste drums that contain Plutonium Contaminated Material (PCM) without opening or disturbing the drum contents.

In-situ real-time characterisation and measurement of materials for effective nuclear waste management

Waste on the Sellafield site must be classified and any hazardous properties identified before handling and disposal. Conducting measurements in situ enables faster, real-time data gathering and analysis, facilitating immediate decision-making regarding the treatment, storage, recovery or disposal of waste.With such varied waste materials at Sellafield, it is recognised that a ‘toolbox’ of different technologies may be required, preferably one that works over a wide range of environments, providing a large suite of data/analysis. Note that not all analysis requires a numerical value to be beneficial and determining an analyte to be below the relevant hazardous waste threshold may be sufficient.

Sellafield Ltd is pursuing innovative solutions to accelerate the characterisation and measurement of materials through in-field testing capabilities.

Lift it, shift it: An alternative approach to asbestos removal

A number of buildings and pieces of equipment due to be decommissioned at Sellafield contain asbestos. There is a high potential risk of operators inhaling asbestos fibres when dismantling asbestos-containing materials (ACM), so the building dismantling process at Sellafield is conducted under strict protocols for handling and transporting ACM.Any solution that can provide sufficient containment of ACM to allow transport of larger components for off-site disposal would reduce the extent of on-site dismantling required, reduce the risk to operators, provide significant cost savings and speed up decommissioning.

Sellafield Ltd requires a safe and cost-effective means to remove asbestos-containing materials from its site. This challenge is seeking solutions that provide encapsulation of these materials prior to their removal for decontamination and disposal.

Improvement of information management in Nuclear Safety Cases

The Nuclear Safety Case is the body of evidence that justifies and demonstrates that nuclear hazards are adequately managed, that operations are safe and that associated risks are reduced to As Low As Reasonably Practicable (ALARP). All related documents are subject to constant ongoing revision. There are no live links between these documents, which exist in a variety of formats.A solution is sought that accurately and efficiently manages the transfer of information within these Nuclear Safety Cases and associated documentation, as well as providing a verifiable audit trail for the changes it proposes.

Sellafield is a large, highly complex nuclear facility with a lot of structured data across its Nuclear Safety Cases, which require manual, resource-intensive processes to cascade changes. Sellafield Ltd is seeking technologies to improve the efficiency of managing its Nuclear Safety Cases and these processes.

Challenge statement - Directional decontamination head deployment into large, congested, highly radioactive vessels.pdf

CP_47 web.jpg

CHALLENGE AIMSSellafield Ltd is looking for technology that can deploy an ultra-high pressure water jetting (UHPWJ) head or other tools into a vessel that can:<ul><li>Cover the full internal surface of the vessel including internal pipework and structures.</li><li>Operate from a nozzle to surface metal distance of 50mm to 100mm.</li></ul>The aim is to decontaminate the vessel by removing the entire internal surface layer of metal.Access into the vessel is achieved via 150mm inspection ports that pass through the 1.5m thick concrete cell wall, then through a 150mm diameter access port on the metal wall of the vessel itself.Technology is being developed to cut an access port into a vessel and then fit a removable access plug through which any technological solution could be deployed.Some vessels have open tops or engineered access ports, but many don’t and would need access to be created. Therefore, the smaller and lighter the solution the better.Aggressive chemicals can be deployed by filling the entire vessel undergoing POCO; however, this produces unacceptable volumes of effluent. The ability to spray chemicals onto the internal surfaces of the vessel would use less of the reagent and reduce the effluent challenge. Ultra-high pressure water jetting (UHPWJ) or electrochemical methods would remove the need for reagents, if the deployment challenge can be solved.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/996576919/"></iframe>The deadline for applications for this challenge is 2pm on Wednesday 21 August 2024.ASSESSMENT OF APPLICATIONSApplications are reviewed against set criteria by a panel of challenge owners, prospective end‐users from our partner organisations, and Game Changers project staff.

Directional decontamination head deployment into large, congested, highly radioactive vessels

Post Operational Clean Out (POCO) of the Sellafield site requires the internal cleaning of large, highly radioactive vessels with complex internal configurations. Sellafield Ltd is seeking innovative solutions for deploying vessel cleaning heads and ultra-high/high-pressure water jetting or spray nozzles to apply decontaminating chemicals and foams inside these structures.The vessels' internal structures can include cooling/heating coils; fluid mixing and transfer devices; instrument dip-legs; internal vessels; and pipe support brackets. All of these internal structures require full surface decontamination. Any tool deployed to clean these internal structures would need to be able to navigate around them whilst cleaning them.

Sellafield Ltd is seeking innovative solutions that will deliver improvements over the current techniques used for deploying vessel cleaning heads into large, highly radioactive vessels with complex internal configurations.

Challenge statement - Fixatives for containment of alpha contamination in gloveboxes.pdf

CP_57 web.png

CHALLENGE AIMSSellafield Ltd would like to identify a fixative that securely fixes airborne alpha particles in place, along with an application method that can be deployed through a 150mm diameter glove port. The fixative solution must be chemically compatible with the glovebox materials, stable under ambient conditions and be as long-lasting as possible. Further details can be found in the “Functional Requirements” section of the challenge statement.Due to the risks of a breach of containment posed by ageing gloveboxes, a solution is desired as soon as practicable. As operations at the Analytical Services Laboratory at Sellafield, which contains many alpha contaminated gloveboxes, are being phased out, this further exacerbates the need for a fixative solution. Other methodologies have been trialled; however, Sellafield Ltd is looking to improve upon these.The ideal scenario would be the capability to coat a glovebox sufficiently for it to be transported without an outer box or crate. Treatment that enables an empty glovebox to act as a container for waste would be an added benefit. Due to the complex states of gloveboxes across site, and the resulting requirements on fixative technology, Sellafield Ltd understands this will be a challenge.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/992847469/"></iframe>The deadline for applications for this challenge is 3pm on Thursday 15th August 2024.ASSESSMENT OF APPLICATIONSApplications are reviewed against set criteria by a panel of challenge owners, prospective end‐users from our partner organisations, and Game Changers project staff.

Fixatives for containment of alpha contamination in gloveboxes

There are approximately 800 gloveboxes across the Sellafield site, made up of a variety of materials such as steel, plastics and elastomers, that contain radioactive material including alpha particles. Due to the advanced age of many of the gloveboxes, they may fail within the next few years, leading to a breach of containment.Sellafield Ltd would like to explore options for effective, strong and durable fixatives that would provide containment of alpha contaminated material within gloveboxes selected for decommissioning, preventing the radioactive contamination from becoming airborne during preparation and transfer of the gloveboxes for processing.

Challenge statement - Non-invasive imaging of in-ground structures.pdf

Full Image Silo ws.jpg

CHALLENGE AIMSSellafield Ltd are looking for a solution to provide a 3D image/model of the subsurface around buildings where as-built records may not be as comprehensive as desired.It is anticipated that successful solution providers should be able to provide a desk study to demonstrate the feasibility of a non-invasive technique.Sellafield Ltd are interested in emerging technologies and techniques such as muon tomography, quantum hall sensing and quantum micro gravity. Please note that the scope of this challenge is not restricted to making use of these specific examples.It may be possible to deploy a device in one of the blind tubes, within the wider Sellafield blind-tube network, for a number of weeks before moving it to another in order to build up information and potentially stitch together surveys. It is acknowledged that there would likely be the need to reconstruct a significant amount of information for presentation or interrogation.A solution to this challenge would be considered to have broad applicability across the site and the mapping of buried services would provide an additional benefit.However, there is a current imperative to gather better information in relation to a known leak from a building on the Sellafield site, which is the single biggest source of in-ground contamination. The current leak from the Magnox Swarf Storage Silo Original Building (MSSS OB) and first extension was declared in 2019. The Magnox Swarf Storage Silos (MSSS) at Sellafield comprise an Original Building constructed in 1962 and three subsequent extensions constructed between 1972 and 1982. The silos contain magnesium cladding or ‘swarf’ that was stripped from Magnox fuel prior to reprocessing and stored under a layer of cover water. The leak rate is around 2.5m3 per day from the Original Building, which is embedded in the ground by approximately 6m.Due to the method of building construction and subsequent, poorly documented, interventions in the ground around the MSSS OB and first extension, the form of in-ground engineering is poorly constrained. There is evidence to suggest that engineering features may be influencing the migration of contamination away from the leak site, and gaining a better understanding of these features would help with developing mitigation strategies.The Original Building goes about 6m underground. Concrete screeding to stop the collapse of excavated slopes was used during construction and these features may be influencing leak migration. The first evidence of a leak occurred when building the first extension at which time considerable excavation and backfilling was undertaken. However, only limited records of the full extent of these works are available. The construction method used changed between the first extension and second extension being built.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/933652837/"></iframe> The deadline for applications for this challenge is 4pm on Friday 26th April 2024 (revised from Friday 19th April).

Non-invasive imaging of in-ground structures

Sellafield Ltd is seeking technologies and approaches to identify the presence and composition of subsurface structures in the vicinity of buildings on the Sellafield site.Like many industrial sites of its age, Sellafield has a complex history of site use including the addition and removal of buildings over an extended period of time. This has resulted in a legacy of redundant physical forms both above and below ground level. This challenge is focussed on emerging technologies and techniques that can produce a 3D image/model of structures beneath ground, in particular around legacy waste storage facilities such as the Magnox Swarf Storage Silos (MSSS).

Challenge statement - Measuring waste bed liquor levels.pdf

Waste bed web.jpg

CHALLENGE AIMSSellafield Ltd needs to ascertain where the liquor level sits within a waste bed of sludge that is being stored under a damp/dry storage regime. This is analogous to measuring the level of groundwater in clay or soil.If there were large differential liquor levels between the six compartments in the MSSS OB, an imbalance of loading would be created on the internal walls due to different hydrostatic pressures on either side of the wall. The capability to confidently measure the liquor levels within the waste bed would allow mitigating action to be taken to ensure that the structural integrity of the internal walls is not exceeded.Sellafield Ltd are open to approaches that either measure the water level directly or infer the water level via other methods of measurement. Measurement of the pressure being exerted on the walls that does not provide measurement of the liquor level in the waste bed would not be discounted but would only partially satisfy the requirements of this challenge.Any solutions to this challenge deployed within the storage compartments of the MSSS OB would need to be radiation tolerant as the compartments contain Intermediate Level Waste (ILW). Sellafield Ltd are open to both in-situ and ex-situ solutions to this challenge.Sellafield Ltd are seeking solutions that can reach the end of the Game Changers Proof of Concept project phase by the middle of 2025. At this point, it is expected that a design scheme would be available with the technology ready for active deployment.FIND OUT MOREPlease download the challenge statement for full details of this opportunity.You can watch a webinar and Q&amp;A session with the challenge owners for more information and details of how to apply.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/923467866/"></iframe>The deadline for applications for this challenge is 4pm on Wednesday 27th March 2024.

Measuring waste bed liquor levels

Sellafield Ltd would like to explore techniques and technology which may be used to measure the liquor level within sludge beds inside waste storage silos. Approaches that either measure the water level directly or infer the water level via alternative methods of measurement are of interest. In-situ and ex-situ solutions to this challenge are invited.The Magnox Swarf Storage Silo (MSSS) Original Building (OB) has six compartments containing corroded sludge consisting mainly of magnesium hydroxide, uranium and uranium oxide. The compartments are regularly topped up with water to keep the sludge under a head of liquor. It is important to be able to measure liquor levels within the waste bed to understand the pressures being applied to the walls of the MSSS OB. The essence of this challenge is to find a method of measuring the liquor level within a waste bed that has been allowed to drain naturally.

Game Changers Technology Talk webinars are aimed at anyone who is interested in technical innovation in the nuclear industry, learning about cutting-edge research developments and understanding how the Game Changers programme helps solve challenges which can’t be met with off-the-shelf solutions.Scroll down for a link to a recording of this month's talks which featured:<h2>The creation, development and future of the FIRMArm modular equipment deployment device</h2>Access is a common issue in the nuclear decommissioning industry. Hazardous environments and hard-to-reach areas and buildings need to be inspected using safe, accurate and repeatable methods.Sheffield-based FIRMA Engineering have created FIRMArm, a flexible and cost-effective platform for use in the nuclear industry and beyond. The portable, easy-to-assemble, modular system can be tailored to each application, with quick assembly and no lifting equipment required. The segmented arm itself, which can extend more than 7m into a cell, can be fitted with an array of end-effectors, such as cameras, radiation monitors, suction devices and 3D scanners. The device is also able to deliver existing instruments and tools to remote locations, in a precise and stable manner.The FIRMArm talk will tell the story of development, from genesis to the present day, as well as touching on future work in the pipeline.<h2>Groundwater and contaminant passive flux estimates</h2>In this talk, Andy Gillett will outline the work conducted by GHD, in collaboration with Cavendish Nuclear, iFLUX and Sellafield, to help refine future groundwater remediation requirements at the Sellafield site.Conventional monitoring techniques of groundwater typically rely on a snapshot ‘spot monitoring’ approach, which may not fully represent groundwater conditions. This can result in a limited understanding of overall solute distribution and transport, leading to inefficient risk assessment and unsuitable remediation plans.Solute mass flux measurements can provide a technically more robust approach to assessing solute transport within groundwater. In this Game Changers funded project, GHD, in collaboration with Cavendish Nuclear, iFLUX and Sellafield, tested a new device using groundwater optimised to specific contaminants of concern. The innovative, simple, disposable device, which is left in-situ, has the potential to provide estimates of groundwater and contaminant flux using the existing borehole network at Sellafield.Key findings from the research conducted as part of this collaboration, along with comparisons to traditional methods and learning points, will be described in this talk.<h2>Watch the recording now:</h2><iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/838719448/"></iframe><h2>﻿</h2>

If you missed this month's talks and would like to catch up, there's a recording link available at the bottom of this page.Use of near-infrared photo spectrometry to identify and quantify organic compounds at distance and in restricted access locations - I﻿mperial College LondonDuring POCO operations, there is a growing need to identify organic compounds in liquids, cruds, and other solids. In particular, the detection of Tributyl Phosphate (TBP), Dibutyl Phosphate (DBP) and Odourless Kerosene (OK). The analysis of these compounds is often complicated due to the limited access to their location. Commonly, the liquids and solids of interest are located within vessels whose only access is via narrow, long lengths of pipework.Imperial College has developed a novel near-infrared spectrometry with miniaturised probes and extended fibre optic cables. This system allows at distance analysis of most organic compounds of interest (including TBP, DBP and OK). The probe and fibre optic cable can pass through pipes as narrow as 15mm ID over distances of at least 20m.The system can also be used to identify the presence and location of immiscible layers in vessels such as pneumercators.This talk will demonstrate how the novel NIR system can be deployed and used to characterise organic compounds during POCO operations.Contaminated concrete removal using controlled heat-induced spalling - The U﻿niversity of SheffieldIn this talk a team of researchers from The University of Sheffield will discuss the work undertaken within the Proof of Concept phase of the Game Changers project “Contaminated concrete removal using controlled heat-induced spalling”. The project proposes a novel approach to remove layers of contaminated concrete, using heat-induced spalling of concrete as the driving mechanism. Traditionally seen as an uncontrolled and undesirable mechanism in structural fire engineering, heat-induced spalling is here exploited to induce and control the removal of the contaminated concrete layer.Jointly funded by Sellafield Ltd and Dounreay Site Restoration Ltd, The University of Sheffield’s proof of concept project focussed on understanding the main challenges, advancing the proposed technology and producing a prototype system.The talk will outline the proposed technology, highlight scientific and technological challenges and discuss opportunities for further development.<iframe class="ql-video" frameborder="0" allowfullscreen="true" src="https://player.vimeo.com/video/813243916/"></iframe>

Safety web.jpg

In response to a Game Changers <a href="https://www.gamechangers.technology/challenge/Improvement_of_information_management_in_Nuclear_Safety_Cases" rel="noopener noreferrer" target="_blank">challenge</a> focused on enhancing information management, three feasibility projects have been awarded funding to develop innovative solutions for Sellafield Ltd. The initiative aims to improve the accuracy, efficiency, and traceability of information transfers within Nuclear Safety Cases and their associated documentation.The Nuclear Safety Case is a critical body of evidence that ensures nuclear hazards are adequately managed, operations remain safe, and risks are minimised to As Low As Reasonably Practicable (ALARP). The associated documents undergo continuous revisions and currently exist in various formats without live links between them. This can result in time consuming processes to maintain consistency and traceability.To address this challenge, three companies have been funded to conduct feasibility studies:<h2>Eigen Ltd – Safety Case Management and Visualisation</h2>Eigen Ltd has proposed a feasibility assessment of the Eigen Safety Barriers application, a commercial off-the-shelf (COTS) solution designed for managing, visualising, and retrieving documents related to Major Accident Hazards (MAHs) in the oil &amp; gas industry. With similarities between MAHs and Nuclear Safety Cases, an adaptation of this solution for Sellafield’s requirements is expected to enhance information management and visualisation for nuclear safety documentation.<h2>Amentum – ThreadSafe: Robust Golden Thread Alignment</h2>Amentum aims to introduce ThreadSafe, an advanced information management approach that automatically captures the relationships and dependencies within safety cases, operating instructions, and maintenance instructions. Utilising advanced natural language processing (NLP) and machine learning tools, ThreadSafe will seek to extract entities and relationships from text-based and unstructured documents, improving data consistency and accessibility.<h2>Cerberus Nuclear Ltd – ClearThread: Providing Clarity in Safety</h2>Cerberus Nuclear Ltd is developing ClearThread, a concept aimed at streamlining Nuclear Safety Case management using large language models (LLM) and optical character recognition (OCR). This system aims to automate the extraction, analysis, and organisation of document content into a centralised database. By processing large volumes of documents in varying formats – including PDFs, Word files, and scanned images – ClearThread is being developed to enable previously non-searchable documents and document structures to become intuitively presented, accessible and therefore easier to manage.﻿The feasibility studies will conclude in April 2025 with pitches for proof-of-concept funding. These projects mark a significant step toward valuable solutions for the integrity and efficiency of nuclear safety documentation management, ensuring enhanced compliance and operational safety for Sellafield Ltd.

Three feasibility projects have been awarded funding to develop innovative solutions aimed at improving the accuracy, efficiency, and traceability of information transfers within Nuclear Safety Cases at Sellafield Ltd.

Fixatives web.png

Sellafield Ltd is tackling the <a href="https://www.gamechangers.technology/challenge/Fixatives_for_containment_of_alpha_contamination_in_gloveboxes" rel="noopener noreferrer" target="_blank">challenge of managing alpha-contaminated gloveboxes</a> as part of its decommissioning programme. The goal is to identify effective, durable fixatives that can prevent alpha particles from becoming airborne during the handling and processing of these gloveboxes. With over 800 gloveboxes slated for decommissioning, ensuring safe containment during transportation and dismantling is a top priority. To address this, Sellafield Ltd initiated a challenge through the Game Changers innovation programme to explore new solutions.Out of thirteen proposals received, the following projects have been awarded funding to develop potential solutions:&nbsp;<h2>FEVDI Nuclear&nbsp;</h2>Based in France and specialising in decontamination, FEVDI Nuclear will focus on adapting their existing LP3 fixative – a widely used product in the nuclear sector&nbsp;– with a focus on enhanced properties and bespoke future-proofing of the fixative. &nbsp;<h2>Cyclife EDF UK&nbsp;</h2>This project will evaluate the application of various fixatives in glovebox environments, emphasising robotic deployment. Spray trials and material compatibility tests will help determine the effectiveness, limitations, and optimal use of the fixatives in real-world scenarios.&nbsp;<h2>Applied Nuclear Physics&nbsp;</h2>Leveraging recent breakthroughs in 3D printing enabling technologies, the team aims to develop an innovative solution for containment integrated with a deployment system. &nbsp;These feasibility studies aim to develop solutions that could enhance containment practices at Sellafield, contributing to safer and more efficient nuclear decommissioning.&nbsp;Given the age and condition of many gloveboxes, there is a strong focus on achieving practical solutions within the next 12 months to minimise potential radiological contamination risks. If these feasibility studies show promising results, further funding could support advancing the projects to the proof-of-concept stage, enabling the development of active containment systems to meet this timeline.&nbsp;

Three solutions receive feasibility funding to tackle the challenge of managing alpha-contaminated gloveboxes as part of Sellafield's decommissioning programme.
