  • Magnox Electric Plc's Strategy for Decommissioning Its Nuclear
    A review by HM Nuclear Installations Inspectorate Magnox Electric plc’s strategy for decommissioning its nuclear licensed sites A review by HM Nuclear Installations Inspectorate Magnox Electric plc’s strategy for decommissioning its nuclear licensed sites Published by the Health and Safety Executive February 2002 Further copies are available from: Health and Safety Executive Nuclear Safety Directorate Information Centre Room 004 St Peter’s House Balliol Road, Bootle Merseyside L20 3LZ Tel: 0151 951 4103 Fax: 0151 951 4004 E-mail: [email protected] Available on the Internet from: http://www.open.gov.uk/hse/nsd ii FOREWORD This report sets out the findings of a review by the Health and Safety Executive’s Nuclear Installation Inspectorate, in consultation with the environment agencies, of the Magnox Electric plc (Magnox Electric) decommissioning and waste management strategies for its nuclear licensed sites. The review was undertaken in accordance with the 1995 White Paper “Review of Radioactive Waste Management Policy: Final Conclusions”, Cm 2919, which stated that the Government would ask all nuclear operators to draw up strategies for the decommissioning of their redundant plant and that the Health and Safety Executive (HSE) would review these strategies on a quinquennial basis in consultation with the environment agencies. The Magnox Electric strategy upon which this review is based was prepared subsequent to the merger of Magnox Electric with British Nuclear Fuels plc (BNFL) but whilst it still remained a separate nuclear site licensee under the Nuclear Installations Act 1965 (as amended). This report therefore considers Magnox Electric’s decommissioning and waste management strategies as of April 2000 for its nuclear licensed sites at: Berkeley, Bradwell, Dungeness A, Hinkley Point A, Hunterston A, Oldbury, Sizewell A, Trawsfynydd and Wylfa; and at the Berkeley Centre; and for the financial liabilities for waste and decommissioning on other nuclear licensed sites (e.g.

Box 100 A-1400 Vienna, Austria NUCLEAR FUEL CYCLE INFORMATION SYSTEM: A DIRECTORY OF NUCLEAR FUEL CYCLE FACILITIES 2009 EDITION IAEA, VIENNA, 2009 ISBN 978–92–0–102109–0 ISSN 1011–4289 © IAEA, 2009 Printed by the IAEA in Austria April 2009 FOREWORD In recent years, there have been rising expectations for nuclear power all over the world to meet the ever increasing demand for electricity. Several countries with nuclear power have declared intentions to build new nuclear power plants to replace their existing capacities or to add new capacities. Several other countries without nuclear power are taking an active interest in launching nuclear power programmes. Nuclear power and nuclear fuel cycle go hand in hand. Hence implementations of such nuclear power programmes cannot be considered without parallel development in the nuclear fuel cycle area. The worldwide nuclear fuel cycle industry comprises several global players which are operating on a commercial basis in more than one country and many other domestic players which are active only in their respective countries. Knowing the current status and the future outlook of the nuclear fuel cycle industry is important not only for meeting the needs of global nuclear power development but also for facilitating the multilateral approach to the nuclear fuel cycle currently being discussed with a focus on ‘assurance of fuel supply’ and ‘non-proliferation of nuclear materials’.

  • Signature Research on Legacy Management at the National Nuclear Laboratory, United Kingdom - 10362
    Signature Research on Legacy Management at the National Nuclear Laboratory, United Kingdom - 10362 A. W. Banford National Nuclear Laboratory, Risley, Warrington, Cheshire, WA3 6AS, United Kingdom ABSTRACT The United Kingdom (UK) National Nuclear Laboratory (NNL) is establishing four Signature Research Areas, which will underpin the future requirements of the UK nuclear Industry. The management of radioactive waste, nuclear plant and sites at the end of operations is a significant challenge in the UK and internationally. Therefore the NNL Signature Research Area on Legacy Management aims to address this challenge. The key theme of the research area is to inform and underpin the development of strategies for legacy management through an understanding of the nature of the waste inventory, the potential endpoints and the identification of possible processing options. This strategic approach aims to identify the key challenges, identify required evolutionary changes to existing technologies and identify areas in which revolutionary change could make most impact. This paper provides a technical overview of the UK’s National Nuclear Laboratory Signature Research Area on Legacy Management; which will focus on the range of technical areas notably; • strategy development • waste, facility and land characterisation • waste behaviour • decontamination • retrieval and remote deployment • decommissioning techniques • contaminated land and site end points. INTRODUCTION A series of four Signature Research Areas have been identified as being central to the United Kingdom National Nuclear Laboratory mission, to provide independent, authoritative advice on nuclear issues. These areas encompass activities which are of strategic significance to the NNL and both the UK and international nuclear industry. The four areas are defined as follows, • Fuel and Reactors • Spent Fuel and Nuclear Materials [1] • Legacy Waste and Decommissioning • Waste Processing, Storage and Disposal Collectively these areas cover most of the nuclear fuel cycle.

  • Directions to NDA in Respect of Springfields Nuclear Site
    ENERGY ACT 2004 Directions to the Nuclear Decommissioning Authority (the NDA) in respect of the Springfields Nuclear Site Made under sections 3, 4 and 16 of the Energy Act 2004 SPRINGFIELDS SITE SUMMARY This summary is not part of the direction This summary is only intended to provide background information in respect of the Springfields Nuclear Site. It sets out the nature of the operations carried out at the site and the cleaning-up or decommissioning work that may be carried out there. However, subject to Ministerial agreement it is for the NDA, following consultation, to determine what the cleaning-up or decommissioning objectives for the site will be and to describe these in its strategy. Under the Energy Act 2004 where the NDA has been given a responsibility it can secure that such a responsibility is carried out by others. The Springfields site, situated near Preston, is the home of BNFL’s fuel manufacturing operations. Fuel manufacturing represents the vast majority of the operations on site and is the core activity of UK Fuels Business (UKFB). The site’s main product streams are Advanced Gas-Cooled Reactor (AGR) fuel, Magnox fuel, Uranium Hexafluoride (Hex) and enriched intermediate products. It is planned that the production of Hex and Magnox fuel will cease before the production of AGR fuel and enriched intermediate products. The other key site activities include clean-up in the form of decommissioning various facilities and processing of uranic residues. Significant decommissioning work has already been undertaken and completed on the site, however the major tranche of site decommissioning will be carried out after the cessation of Hex conversion and Magnox fuel production on the site.

  • Environment Agency (A Non-Departmental Public Body, Partly-Sponsored by Defra) Regulates Radioactive Substances and Radioactive Waste in England
    SPRINGFIELDS FUELS LIMITED (SFL) SITE STAKEHOLDER GROUP REPORT FOR THE PERIOD NOVEMBER 2014 – MARCH 2015 FOREWORD This report is a brief summary of our regulatory activities relating to Springfields since the last regular site stakeholder group meeting. The Environment Agency (a non-departmental public body, partly-sponsored by Defra) regulates radioactive substances and radioactive waste in England. On nuclear sites such as Springfields, we regulate radioactive waste disposals by determining applications and granting Permits under the Environmental Permitting (England and Wales) Regulations 2010. These Regulations cover the disposal of gaseous and liquid radioactive wastes and the disposal and transfer of solid radioactive wastes. Many of the site’s activities, including operation of chemical plant and combined heat and power plant, fall within a different section of the Environmental Permitting Regulations, for which a separate Environment Agency Permit is in force. In our capacity as joint Competent Authority with the Office for Nuclear Regulation (ONR), we regulate the Springfields site under the Control of Major Accident Hazards Regulations 1999 (COMAH). We also determine and issue regulatory permissions under the Transfrontier Shipment of Radioactive Waste and Spent Fuel Regulations 2008 and the Greenhouse Gas Emissions Trading Regulations 2012. We help produce the annual “RIFE” Report. “Radioactivity in Food and the Environment” is a collaboration between the Food Standards Agency and the UK Environment Agencies (ourselves, the Scottish Environment Protection Agency, the Northern Ireland Environment Agency and Natural Resources Wales); it summarises the previous year’s results of all the Agencies’ radiological monitoring of food and the environment. Routine Matters We carried out a visit to discuss the operator’s approach to decommissioning redundant facilities, including a visit to the former Magnox fuel canning plant.
