AbstractAn integral part of decommissioning the Nuclear Decommissioning Agency's (NDA) Dounreay site is the management of the solid low level radioactive waste (LLW). The United Kingdom Atomic Energy Authority (UKAEA) has developed and progressed a technical and stakeholder programme that has enabled it to submit a robust Planning Application to Highland Council (HC) for New LLW Disposal Facilities at Dounreay and to submit substantive preliminary safety and environmental cases to the Nuclear Installations Inspectorate (NII) and the Scottish Environment Protection Agency (SEPA). To UKAEA’s knowledge this is the most advanced project in the UK for new LLW disposal facilities. Experience has been gained in progressing the Best Practicable Environmental Option (BPEO) Study, working with regulators in unfamiliar areas, and undertaking groundbreaking stakeholder consultation. Key lessons learnt are that stakeholders should be engaged in dialogue on the project as early as possible, documentation must be high quality and tailored to its audience, and internationally respected and credible consultants must be involved.

The independent monitoring of solid low level radioactive waste (LLW) in the United Kingdom is undertaken by NNC Limited on behalf of The Environment Agency to ensure that disposals are within the authorised limits. Waste consignments are seized by the Agency prior to disposal and are transported to the Waste Quality Checking Laboratory (WQCL) at Winfrith, where the contents are analysed and assessed by destructive and non-destructive testing. All work performed at the laboratory is qualified by a Quality Assurance System which has been accredited by the United Kingdom Accreditation Service (UKAS). This paper outlines the regulatory framework for control of LLW disposals in the UK and describes the techniques used at WQCL for radioactive waste assessment.

The UK National Low Level Waste Repository (LLWR) is located near to the village of Drigg in West Cumbria. It is the principal site for disposal of solid Low Level Radioactive Waste (LLW) in the United Kingdom. This paper describes the program of work currently being undertaken by the site’s operators, (LLW Repository Ltd and its newly appointed Parent Body Organisation), to extend the life of the LLWR and reduce the overall cost of LLW management to the UK taxpayer. The current focus of this program is to prevent disposal capacity being taken up at LLWR by waste types which lend themselves to alternative treatment and/or disposition routes. The chosen approach enables consignors to segregate LLW at source into formats which allow further treatment for volume reduction or, (for wastes with lower levels of activity), consignment in the future to alternative disposal facilities. Segregated waste services are incorporated into LLW Disposal commercial agreements between the LLWR operator and waste consignors.

AbstractThe safe implementation of geological disposal must be underpinned by sound science. This paper describes the approaches taken by the Nuclear Decommissioning Authority Radioactive Waste Management Directorate, the implementing body for geological disposal in the UK, to build an evidence base of scientific data and understanding which is robust to scrutiny and so provides confidence in the safety of geological disposal.

Nirex is the organisation responsible for long-term radioactive waste management in the UK. Our Mission is to provide the UK with safe, environmentally sound and publicly acceptable options for the long-term management of radioactive materials. The United Kingdom has a significant legacy of long-lived intermediate level radioactive waste. This has arisen from 50 years of investigation and exploitation of nuclear technology. Some of the waste is stored in old facilities that do not provide the standards of containment that would be incorporated in modern facilities. Also the risk to people and to the environment from the inventory in these facilities will increase with time as the structures age and degrade, increasing the chance of containment failure. There is, therefore, a need to retrieve this raw waste and process and package it to make it demonstrably safe for continued storage, pending a decision on disposal of radioactive waste. This packaging should, as far as is practicable, be compatible with the UK long-term waste management strategy. Nirex has developed its Phased Disposal Concept for intermediate and low-level radioactive waste. Based on that concept, Nirex has developed waste package specifications and carries out assessments of waste packaging proposals. For legacy wastes it may not always practicable to demonstrate full compliance with all Nirex disposal criteria. This paper describes an approach, agreed between Nirex and BNFL, for managing these wastes. The proposed approach takes account of long-term waste management issues whilst recognising the need for timely improvement of storage conditions.

Checking low level wastes requires the detection of sub-milligram levels of plutonium. This is an extreme challenge for passive neutron coincidence counting as the levels of true signal are close to the background signal caused by cosmic ray interactions. The origin of cosmic-induced background is discussed. We describe the Hexagon 2000 passive neutron coincidence counter that has been designed and built for waste quality checking of low-level radioactive waste in the UK for the Environment Agency. The instrument uses computed neutron coincidence counting and improved filtering of high multiplicity cosmic-induced events. The instrument also correlates background signal with atmospheric pressure to further increase sensitivity. Preliminary measurements of background data and of test drums containing small amounts of plutonium are described.

UKAEA’s mission at its Dounreay establishment in the north of Scotland is to restore the site so that it can be used for other purposes, with a minimal effect on the environment and requiring minimal attention by future generations. A Dounreay Site Restoration Plan (DSRP) has been produced. It sets out the decommissioning and radioactive waste management activities to restore the site within the next 60 years. Management of solid low level radioactive waste (LLW) that already exists, and that which will be produced as the DSRP progresses is an essential site restoration activity. Altogether around 150,000m3 (5.3Mft3) of untreated LLW could arise. This will then need to be treated, packaged and managed, the resulting volume being around 200,000m3 (7Mft3). A project to develop a long term strategy for managing all Dounreay’s existing and future LLW was initiated in 1999. The identification of complete solutions for management of LLW arising from the site restoration of Dounreay, an integrated reactor and reprocessing site, is novel in the UK. The full range of LLW will be encountered. UKAEA is progressing this specific project during a period when both responsibility and policy for UK decommissioning and radioactive waste management are evolving in the UK. At present, for most UK nuclear operators, there are no recognised routes for disposing of significant volumes of decommissioning LLW that has either lower or higher radioactivity than the levels set by BNFL for disposal at the UK national LLW disposal site at Drigg. A large project such as this has the potential to affect the environmental and social conditions that prevail in the area where it is implemented. Local society therefore has an interest in a project of this scale and scope, particularly as there could be a number of feasible solutions. UKAEA is progressing the project by following UK established practice of undertaking a Best Practicable Environmental Option (BPEO) study. UKAEA has no preconceptions of the outcome and is diligently not prejudging issues prematurely. The BPEO process draws experts and non-experts alike into the discussions and facilitates a structured analysis of the options. However to permit meaningful debate those options have to be at first generated, and secondly investigated. This has taken UKAEA two and a half years in technical assessment of options at a cost of around £23/4M. The options and issues have been investigated to the depth necessary for comparisons and valid judgements to be made within the context of the BPEO study. Further technical evaluation will be required on those options that eventually emerge as the BPEO. UKAEA corporate strategy for stakeholder participation in BPEO studies is laid out in “Restoring our Environment”, published in October 2002. This was developed by a joint approach between project managers, Corporate Communications, and discussion with the regulators, government departments and Scottish Executive. An Internal Stakeholder Panel was held in March 2003. The Panel was independently facilitated and recorded. Eight Panel members attended who provided a representative cross-section of people working on site. Two External Stakeholder Panels were held in Thurso at the end of May 2003. A Youth Stakeholder Panel was held at which three sixth form students from local High Schools gave their views on the options for managing Dounreay’s LLW. The agenda was arranged to maximise interactive discussion on those options and issues that the young people themselves considered important. The second External Stakeholder Panel was based on the Dounreay Local Liaison Committee. Additional participants were invited in acknowledgement of the wider issues involved. As the use of Drigg is an option two representatives from the Cumbrian local district committee attended. From all the knowledge and information acquired from both the technical and stakeholder programmes UKAEA will build up the objective line of argument that leads to the BPEO emerging. This will be the completion of this first stage of the project and is planned for achievement in March 2004. Once the BPEO has been identified the next stage will be to work up the applications for the authorisations that will be necessary to allow implementation of the BPEO. Any facilities needed will require planning permission from the appropriate planning authority. The planning application could be called in by a Minister of State or a planning inquiry convened. During this next stage attention will be paid to ensure all reports and submissions are consistent and compliant with regulations and possible future legal processes. Stakeholder dialogue will continue throughout this next stage moving on from disussion of options to the actual developments. The objective will be to resolve as many issues stakeholders might raise prior to the submissions of applications and prior to the regulators’ formal consultation procedures. This will allow early attention to those areas of concern. Beyond the submission of applications for authorisations it is unwise to speculate as nuclear decommissioning will be then organised in the UK in a different way. The Nuclear Decommissioning Authority will most probably be in overall control and, particularly for Dounreay, the Scottish Executive may have developed its policy for radioactive waste management in Scotland.

The early ’80s UK programme for deep geological disposal of high-level radioactive waste was advanced and at the stage of characterising potential sites. When this project was put on hold in the mid ’80s, much expertise in this field was lost. In Japan R&D in the ’80s resulted in major generic safety assessments to demonstrate feasibility in the ’90s. This led to the establishment of NUMO (Nuclear Waste Management Organization of Japan) and the initiation of siting based on volunteerism. This novel approach required more flexible methodology and tools for site characterisation, repository design and safety assessment. NUMO and supporting R&D organisations in Japan have invested much time and effort preparing for volunteers but, unfortunately, no discussions with potential host communities have yet developed to the point where technical work is initiated. Presently, the UK is moving forward; with the NDA RWMD (Nuclear Decommissioning Agency Radioactive Waste Management Directorate) adopting a NUMO-style volunteering approach and a flexible design catalogue. Communities have already shown interest in volunteering. The situation is thus ideal for collaboration. The paper will expand on the opportunities for the UK and Japan to benefit from an active collaboration and discuss how this can be most efficiently implemented.

AbstractThis paper gives an overview of the geosphere research studies being undertaken by the Radioactive Waste Management Directorate (RWMD) of the Nuclear Decommissioning Authority. The approach of the RWMD in the current generic phase of the UK managing radioactive waste safely (MRWS) programme is to maintain an understanding of key processes and to carry out research and development into techniques so capability can be built. Although RWMD can demonstrate a general understanding of geosphere processes at this stage in the UK project, it is recognized that this will need to be made site-specific as the MRWS programme progresses. An understanding of the geosphere at the selected site(s) will be an important part of the future programme. Where possible, the RWMD will participate in international studies so that relevant site-based information can be accessed. In this way, the RWMD will be prepared for site-specific work in stage 5 of the MRWS process.
