NDA’s Direct Research Portfolio for “Nuclear Materials and Spent Fuel (NM & SF)”

Eden Nuclear and Environment Ltd and our partners are delighted to have been awarded a place on the Nuclear Decommissioning Authority’s Direct Research Portfolio (2020-2024) for provision of “Nuclear Materials and Spent Fuels” services.

Our team, which includes Integrated Decision Management (IDM), NSG Environmental Limited, Nuclear-21, TÜV UK and the University of Bristol, is looking forward to supporting NDA on this important Framework over the next four years.

The Framework Contract is intended to support the full scope of R&D to develop and implement the Nuclear Materials & Spent Fuels (NM&SF) strategies as outlined in the NDA Strategy. The topics covered include:

  • Plutonium disposition: One of the most complex challenges facing the NDA in dealing with the UK’s nuclear legacy is the management and, ultimately, disposition of the inventory of separated plutonium held in the UK.
  • Uranics management: The size of the UK’s separated unirradiated and previously irradiated uranium-containing stocks is large and comes in a variety of chemical and material forms. The current strategic approach is continued safe and secure storage pending the identification of opportunities for sale for reuse where practicable or conditioning to an appropriate form for disposal.
  • Spent Fuels Management: The NDA inventory of spent nuclear fuels is diverse and consists of large quantities of Advanced Gas-cooled Reactor (AGR) fuels with smaller quantities of Magnox and non-standard diverse fuel types, which are referred to as ‘exotic fuels’. The fuels have a variety of enrichment and irradiation histories.

Dr Andy Baker, Managing Director of Eden Nuclear and Environment, said

“The NDA’s DRP Framework is vitally important to the delivery of the UK’s civil nuclear decommissioning mission. We look forward to joining with NDA and other teams to deliver collaborative projects utilising the deep and diverse expertise from our team and our new partners.”

A new Waste Metrics Dashboard for the National Waste Programme Office

Eden Nuclear and Environment Ltd recently produced a new version of the Waste Metrics Dashboard, including an accompanying Guidance Document and a Formula Booklet, for the National Waste Programme Office (NWPO).

The Waste Metrics Dashboard is a tool to report progress made by the UK radioactive waste industry in terms of the volume of radioactive waste managed via disposal and diversion; and any associated metrics such as CO2 avoidance and cost avoidance.  The Dashboard is produced on a monthly basis using a MS Excel spreadsheet (the Dashboard Spreadsheet).

Eden NE’s main emphasis throughout this project was developing documents and the Dashboard spreadsheet so that they could be used easily by people with little technical experience or experience of Excel.  A key advancement that Eden NE made to the Dashboard spreadsheet itself was the introduction of a number of reporting sheets that allow users to interrogate data for specific metrics, sites and time periods.

Cumbrian Alchemy book

Eden NE’s Paul Abraitis is proud to have provided a chapter to the Cumbrian Alchemy book on the natural history of radioactivity in Cumbria. The book is part of the Cumbrian Alchemy project by New York artist Bryan McGovern Wilson and University of Cumbria professor of fine art Robert Williams. The project was an ambitious contemporary art project which aimed to explore the relationship between the nuclear, mining and renewables industry of Cumbria, with the landscape archaeology and folklore of North Lancashire and Cumbria. In support of Paul and the project curators, Hannah attended a recent lecture given by author Robert Williams. The lecture highlighted the importance of maintaining records, knowledge and memory for a long term nuclear repository. Particular emphasis was placed on the preservation of language for the transmission of knowledge over deep time futures. The lecture also showcased the artwork featured in the book by Bryan McGovern Wilson as well as animations by Japanese artist Isao Hashimoto. It is hoped that these pieces will help preserve the memory of nuclear facilities over timescales that transcend time beyond human lifespans.
The Cumbrian Alchemy project has been exhibited throughout the UK and was featured alongside the Nuclear Cultures, Perpetual Uncertainty Exhibition in Sweden by Dr Ele Carpenter. Preservation of the memory of a nuclear repository over very long timescales is also an interest of Eden NE’s Shelly Mobbs who has supported Ele Carpenter’s work on Nuclear Culture for several years.
Robert and Bryan hope that their project will stimulate many more conversations on how we can communicate to people where our radioactive waste is stored 100 000 years from now.

We are very pleased to welcome two new associates who will be working with us in the future andwho’s expertise will be available to our clients.

Pete BurgessPete Burgess (Radiation Metrology Ltd) has spent his working life since leaving Aberdeen trying to produce equipment and techniques for making the measurement of ionising radiation better, easier, safer and cheaper, as well as teaching people to do the same.  During this time, he invented the detection method for the Thermo EPD, one of the world’s leading electronic dosemeters, and performed the first delicensing review for many years for the NII.   He has contributed many scientific papers, advised the HSE, EA, NII and ONR, found radium paint contamination, stuck dosemeters on and performed measurements in Ukrainian coal trains for IAEA, worked out why the RBE associated with pi mesons seemed erratic and has worked inside the reactor compartment of a nuclear submarine. He is a regular contributor to SRP meetings, has co-authored many of the NPL GPG series on ionising radiation measurement and chaired the group that produced the SRP guidance on dealing with radioactive legacies.

John HeathcoteJohn Heathcote has a broad background in physical sciences and chemistry and is a hydrogeologist by profession.  He has been involved in the nuclear industry for over twenty-five years.  John’s first involvement was in the hydrogeological characterisation of the 1000 m thick sedimentary cover sequence for the possible deep waste repository at Sellafield, including evolution of the flow system over glacial cycles.  Latterly, John has specialised in the characterisation of radioactively contaminated land and the preparation of environmental safety cases for site closure of a nuclear site.  His work at Dounreay over the last ten years or so has seen him cover most things to do with the ground, including the parts of buildings attached to it: contaminated land, waste disposal to ground, groundwater pollution assessment, ground and surface water management. John has developed a number of skills during his career such as : radioactive ground characterisation (radiochemical analysis design, interpretation and statistics); chemically contaminated land; interpretation of complex datasets; hydrogeology and hydrology; and Scottish environmental legislation.  He was a member of Dounreay’s top-management technical review committee for nine years up to retirement and has some knowledge of most things nuclear, from criticality control to ventilation requirements.  He has even used this knowledge in optimisation of house thermal design.  He now seeks to use these skills to support a range of clients dealing with similar issues.

Eden NE is happy to work with Pete and John and to be able to share their expertise with our clients.

New Quality Management System for Eden Nuclear and Environment Ltd.

ISOQAR (200x148px)Eden Nuclear and Environment has completely reviewed and updated its Quality Management System during 2014, led by Alex Rankine; not only in order to comply with the requirements of ISO9001, but also to be a more useful tool for the company. The new system is based on ‘issosmart’ developed by Rosewood Keen Management Services.

Following its introduction a new programme of internal audits was initiated followed by an external audit early in September by our new registration company ISOQAR. Evidence given throughout the audit convinced the auditors that plans are in place to manage and maintain the quality system effectively. The audit team concluded that Eden Nuclear and Environment has established and maintained its management system in line with the requirements of the standard and demonstrated to the audit team that it has the ability to systematically achieve the requirements for products and or services within the scope of its activities and in accordance with its policy and objectives. Our registration has been renewed until October 2017, with a surveillance audit planned to take place in July 2015.

In particular we have established an expertise in the provision of Environmental Cases and advice relating to regulatory requirements under the provisions of the Town and Country Planning Act and the Euratom Treaty.

Working in association with our partners, Golder Associates and WRc, we have delivered reviews of local beach use, coastal particles analysis, provision of Environmental Impact Assessments and associated Environmental Statements, advice relating to regulatory regimes and Permitting, options for the disposal of Low Level Wastes and the transfer of materials enabling decommissioning of older facilities on site.

Plymouth Large Scale Housing Transfer – Environmental Risk & Liability Assessment

Durham (200x145px)Eden NE has completed an environmental risk and liability assessment of 18,548 dwellings and c6million m2 of land. Eden NE used advanced technologies and skills to map housing related assets and environmental hazards to allow assessment and profiling of key risks and the calculation of financial liability.

The approach assessed over 100 spatial datasets and evaluated contaminated land, flooding, subsidence, natural hazards and asbestos containing materials for every individual asset, calculated the risks and the financial liability associated with the risks. The core work was subsequently extended to include an assessment of over 36 parcels of additional land which were allocated for the specific purpose of housing development. The assessment included a more enhanced constraints assessment and financial evaluation based on housing development.

The work was undertaken on time within 12 weeks and within the Council budget. The work undertaken emphasises Eden NE’s skills in environmental data, risk modelling, asset management and liability assessment.

Eden NE has supported the Radioactive Services Division of Augean PLC in the development of the East Northants Resource Management Facility since 2012. Initially providing input to the planning enquiry and then producing an Environmental Safety Case (ESC) to support revision of a Permit for the receipt and disposal of low level radioactive waste disposal at the site.  An ESC is a requirement of the Environment Agency that shows how a near-surface facility for solid radioactive waste disposal meets their requirement that people and the environment are protected from the hazards associated with disposals to the facility. The assessments undertaken to support the ESC cover operational and post-closure periods and future development of the site.
