Over many years TÜV SÜD Nuclear Technologies have become a trusted partner to SLCs in the development and underpinning of compliant waste management strategies. We add value by our understanding of the technical issues and the ability to quickly and efficiently identify the underpinning work required to deliver complex and challenging projects.
We bring together our comprehensive knowledge of site operations, decommissioning and waste requirements, environmental and safety compliance and stakeholder awareness in order to support the client with robust decision making.
Many of TÜV SÜD Nuclear Technologies staff members have undertaken roles in client organisations where they are responsible for reviewing safety or environmental case documentation either independently or as part of a project sanctioning committee. Having high caliber technical staff is supplemented by a range of tools based on a "Waste Led" philosophy that aid the identification and understanding of the technical risks of a project. Furthermore, these tools can be used to remove uncertainty and focus work on what is actually needed. "Waste Led", however, is equally applicable to Fuel and Nuclear Materials and encompasses Decommissioning as a step in the project lifecycle.
The tools used are:
- Process Wiring Diagrams (PWD) with associated R&D Tables
- Data Quality Objectives (DQO) processes
- R&D Identification
- Strategy Development Tool
- Decision Logic Diagrams
- Technology Roadmaps
- Technology / Process Maturity Assessment
Each tool can be undertaken independently, however, an integrated approach ensures a robustly underpinned strategy that is readily defensible.
TÜV SÜD Nuclear Technologies has applied its Waste Led philosophy to several subjects and with most clients across the nuclear industry.
TÜV SÜD Nuclear Technologies personnel have a broad and in-depth perspective of the issues associated with the management of spent irradiated fuel and the technical solutions to these challenges.
We have extensive experience and understanding of wet fuel storage operations and of reprocessing facility operations. This includes the treatment and passivation of the subsequent waste streams. We also have extensive knowledge of advanced reprocessing technologies.
We are able to support our clients in
- development of spent fuel management strategies and planning
- definition and management of R&D
This is performed without bias and prejudice and with a thorough and in depth understanding of the challenges that are faced.
TÜV SÜD Nuclear Technologies have been involved in several projects associated with spent fuel including but not limited to:
- Nuclear Fuels Support (NDA)
- Exotic Fuels Support (NDA)
- Review of Options for Irradiated Fuel Container Packaging & Cask Loading (DSRL)
- Technical Specification for the Removal of Fuel (Magnox Ltd)
- Development of Oxide Fuel Strategy (NDA)
- Strategic support through the development of baseline strategies and identification of needs, risks and opportunities in the delivery of those baselines for the irradiated and un-irradiated (including special nuclear materials) transfers from Dounreay to Sellafield (DSRL).
- Support to Sellafield Pile Fuel Storage Project in development of strategies for the characterisation and management of their fuels
- Provision and technical and strategy support to the Sellafield First Generation Magnox Storage Pond Project.
- Support to the development of a BAT and ALARP scheme for fuel and fuel bearing material as part of the Enterprise Fuels Study (SL).
TÜV SÜD Nuclear Technologies have worked closely with the NDA on spent fuel strategy for several years and consequently have a good understanding of the current and emergent issues the NDA estate faces regarding Spent Fuel Management.
TÜV SÜD Nuclear Technologies have been utilising the principles of the DQO process since 2008 when we applied it to the Chapelcross ILW characterisation and strategy project. The process had originated in the US EPA for contaminated land sampling however we adapted it for a waste focused management of higher activity waste specifically to ensure a logical development of planning of the collection and management of underpinning data required for the technology development.
We have continued to develop the approach and have applied it to several different projects and challenges, for example, TÜV SÜD Nuclear Technologies have undertaken several workshops for the Sellafield BEP project where a series of decision logic diagrams were created to ensure that the underpinning data requirements (trials) identified previously in a Functional Requirements Workshop could be validated and any additional requirements identified captured. The data logic process was a systematic process that ensured all relevant underpinning trials could be identified and assist in the removal of nugatory work from the programme.
It was important to note that the purpose of the workshops was to identify the questions to be answered in terms of the work that was required to be done and it was not intended to provide the answers as these would be provided by the relevant research organisations. It was anticipated that once the trials were in progress there may have been additional or subsequent requirements identified however the DQO process could be iterated to ensure continuous capture of data needs. Indeed, the DQO process follows a seven-step systematic approach, where one, several or all steps may be reconsidered as new information become available. Therefore, DQO logic diagrams could be revisited through the task's lifecycle as new information on the problems studied arose.
TÜV SÜD Nuclear Technologies have significant experience in the application of BAT (England and Wales) and BPM (Scotland) to various nuclear operators and SLCs in the UK. We also understand the close link between BAT and ALARP and where possible bring together our environmental and safety expertise to aid project delivery.
We offer a range of services including:
- Option assessment, including use of the NDA value framework
- Claims argument evidence assessment
- Strategic BAT Analysis
- Tactical BAT Analysis
- Workshop facilitation
- Strategy development incorporating EA, ONR and Joint Regulatory guidance.
We have supported significant projects at Sellafield including BEP, FGMSP and PFSP and undertaken numerous studies at Magnox, DSRL and EDF.
TÜV SÜD Nuclear Technologies has extensive experience in successfully supporting site licensees in their applications for discharge authorisations/permits under the Environmental Permitting (England and Wales) Regulations 2010 and its legislative predecessor RSA 93. The authorisations/permits are periodically reviewed by the regulator and TÜV SÜD Nuclear Technologies has provided support to a range of licensees including input to the new nuclear build programme. This includes supporting EDF NNB Genco in the preparation of initial environmental permit applications for Hinkley Point C and progressively building appropriate company processes and capability for compliance.
TÜV SÜD Nuclear Technologies also supported EDF in the preparation of an Environmental Permit application to allow the discharge and disposal of radioactive waste from Hinkley Point C. The EA indicated, as part of the GDA process, that the sampling and monitoring systems for the EPR reactor must be demonstrated as BAT and a definition and justification of the proposed radioactive discharge sampling and monitoring arrangements was required to support the application. The following tasks were completed by TÜV SÜD Nuclear Technologies.
- Gap Analysis to identify the work required for the Environmental Permit.
- Completion of Draft Definition and Justification Document - The information requirements for the Permit Application, review of Sizewell B practices and the subsequent Gap Analysis report.
- Completion of Final Document which included a justified definition of the proposed discharge monitoring regime in a form suitable for use in support of the Environmental Permit application.
TÜV SÜD Nuclear Technologies has also supported Sellafield Ltd in meeting their environmental permitting requirements in relation to the receipt of Nuclear Material from the Harwell site for storage and treatment at Sellafield. The scope of work involved ensuring that any new environmental permits, or variations to existing permits, are obtained as necessary in accordance with EPR RSR. The focus was on aerial discharges and assessing the environmental impact as a result of increased storage requirements and processing throughput. In addition, compliance with Article 37 of the Euratom Treaty and non-radioactive environmental legislation was covered within the scope of the support provided by TÜV SÜD Nuclear Technologies.
TÜV SÜD Nuclear Technologies also supported Horizon Nuclear Power's Assurance function in the independent review of the EP-RSR application and ensured consistency with the Site Licence Application documentation.
Support has included independent review and inspection of a new build operator's EP-RSR permit and supporting management arrangements. This included review of the station discharges and limit setting; BAT case, environmental monitoring and management arrangements chapters underpinning the EP-RSR permit application and other environmental permit applications.
This also included an inspection of Horizon environmental management arrangements through a series of audits and inspection interviews with the Horizon senior management team and project delivery units at the Horizon technical office, Gloucester.
TÜV SÜD Nuclear Technologies have experience of Environmental Impact Assessment as applied to the requirements for Nuclear Reactors (Environmental Impact Assessment for Decommissioning) Regulations, 1999 and as applied to the Design Consent Order (DCO) required by the planning inspectorate for Nationally Significant Infrastructure Projects (NSIPs).
EIADR is a legal instrument that requires the environmental impact of decommissioning nuclear power stations, and other nuclear reactors, to be considered in detail before consent for the decommissioning work to go ahead is given. TÜV SÜD Nuclear Technologies have first-hand experience of EIA-DR as applied to the decommissioning reactor fleet in the UK and have delivered enabling studies for currently operational stations prior to their planned decommissioning.
We have consults who have been directly involved in the DCO for Horizon Nuclear Power's Wylfa Newydd Nuclear Power Station in a management of the DCO process itself and in the independent review of parts of the DCO application and its consistency with other Environmental Permits.
TÜV SÜD Nuclear Technologies has many years experience in production and assessment of documentation for the handling, storage and transport of radiological materials.
We have detailed knowledge of IAEA Transport Regulations, have been involved in developing the RWM Generic Waste Package Specification and have undertaken Transport Package Safety Assessments on behalf of RWM.
Additionally,TÜV SÜD Nuclear Technologies are supported by its Parent organisation TÜV SÜD, who have extensive experience preparing Transport Package Design Safety Reports for Competent Authority Approval in Germany. This has included assessments of:
- Heat removal, tightness and integrity
- Incident studies e.g. aircraft crash
- Impact, thermal and structural analyses of packages
- Impact evaluation of impact drop heights
TÜV SÜD Nuclear Technologies provides an extensive range of services, relating to the production and management of LoC submissions and their review. These are required to ensure that when waste is packaged by waste producers it is in a form which is suitable for safe storage, transport, handling and potential disposal. We also assist in the development of future waste management strategies including the provision of advice on RWM requirements. Over several years we have had a number of staff seconded into client organisations and RWM itself supporting the production of LoC documentation.
Examples of our work for NDA RWM:
- The assessment of waste packaging submissions from waste producers.
- Production of RWM Guidance Notes on a range of subjects including the management of tritium bearing wastes and the use of organic polymers to encapsulate ILW.
Examples of our work for waste producers and site licensees:
- Facilitating formal discussions with RWM on waste packaging proposals.
- Gathering data required to support the production of waste packaging submissions (e.g. waste inventory studies).
- Preparing formal waste packaging submission documents.
- Managing interactions with RWM during their assessment of LoC submissions.
