    小型飛翔体／海外 ［Format 2］ Technical Catalog Category Airborne contamination sensor Title Depth Evaluation of Entrained Products (DEEP) Proposed by Create Technologies Ltd & Costain Group PLC １．DEEP is a sensor analysis software for analysing contamination. DEEP can distinguish between surface contamination and internal / absorbed contamination. The software measures contamination depth by analysing distortions in the gamma spectrum. The method can be applied to data gathered using any spectrometer. Because DEEP provides a means of discriminating surface contamination from other radiation sources, DEEP can be used to provide an estimate of surface contamination without physical sampling. DEEP is a real-time method which enables the user to generate a large number of rapid contamination assessments- this data is complementary to physical samples, providing a sound basis for extrapolation from point samples. It also helps identify anomalies enabling targeted sampling startegies. DEEP is compatible with small airborne spectrometer/ processor combinations, such as that proposed by the ARM-U project – please refer to the ARM-U proposal for more details of the air vehicle.

  • Beauly to Loch Buidhe 275Kv Overhead Line Reinforcement
    Beauly to Loch Buidhe 275kV Overhead Line Reinforcement About Scottish Hydro Electric (SHE) Transmission plc Scottish and Southern Energy Power Distribution is part of the SSE plc group pf companies. We own, maintain and invest in the electricity networks in the north of Scotland – the electricity transmission network (132kV and above) and the electricity distribution network (below 132 kV). In Scotland, Scottish and Southern Energy Power Distribution is made up of two businesses: Scottish Hydro electric Transmission (SHE Transmission) owns and maintains the electricity transmission network across the north and west of Scotland, in some of the UKs most challenging terrain; and Scottish Hydro Electric Power Distribution (SHEPD) operates the high and low voltage electricity network that distributes electricity to around 700,000 customers in north mainland Scotland and Scottish islands. SHE Transmission owns around 5,000km of electricity transmission infrastructure which spans about 70% of the land mass in Scotland. Electricity networks like this provide a physical link between electricity generators and electricity users. We have three main objectives over the next decade: To keep the lights on for our customers To invest for a greener future; and To minimise, as far as possible, our impact on the environment. Our network crosses some of the UK’s most challenging terrain – including some circuits which are over 750 metres above sea level and up to 250km long. The landscape and environment that contribute to the challenges we face also give the area a rich resource for renewable energy generation. There is enough demand to connect from new wind, hydro and marine generators which rely on us to provide a physical link between the new sources of power and electricity users.

  • Royal Society of Edinburgh Inquiry Into Scotland's Energy Future: Nuclear Industry Association Response the Nuclear Industry A
    Royal Society of Edinburgh inquiry into Scotland’s Energy Future: Nuclear Industry Association response The Nuclear Industry Association (NIA) welcomes this opportunity to respond to the Royal Society of Edinburgh’s inquiry into Scotland’s Energy Future. As the RSE notes, this is propitious timing for such a survey given the major changes taking place in the Scottish energy sector and in the light of the Scottish Government’s proposed new energy strategy. About the NIA NIA is the trade association, information and representative body for the civil nuclear industry in the UK. It represents about 260 companies operating across all aspects of the nuclear fuel cycle, including several Scottish companies. Many of these companies actively support the UK’s nuclear sector, including the operation of Hunterston B and Torness nuclear power stations, and decommissioning activities at Hunterston A, Dounreay and Chapelcross. Future Scottish Energy Mix As a trade body representing the nuclear industry the NIA is not in a position to respond to all of the detailed questions set out in the RSE’s consultation. We should however like to make some broader points relating to the future Energy Mix question. As we noted in response to their consultation earlier this year the NIA supports the Scottish Government’s strong commitment to fighting climate change and to devising an integrated energy strategy, including decarbonisation, to deliver this. However we strongly believe that a decarbonisation target (for providing 50% of Scotland’s energy consumption), rather than a simple renewables target, would be the best means of achieving this. This would facilitate the most efficient and cost effective mix of low carbon technologies, and benefit the Scottish consumer.

  • 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.

This report is the first part of this study and deals with plutonium. The scope of this initial review, in line with Government initiatives on openness, provides information on the movement of plutonium to and from the Atomic Weapons Establishment (AWE) Aldermaston where all fissile components for nuclear warheads have been manufactured. This work complements the SDR announcement of the current stock of nuclear material, held outside international safeguards, for national security purposes. The SDR also announced that surplus stock would be placed under Euratom safeguards and made liable to inspection under the terms of the safeguards agreement between the UK, Euratom and the IAEA. The plutonium stored at Sellafield has now been placed under safeguards and the process of transferring the 0.3t of surplus weapons grade plutonium from Aldermaston to a civil nuclear site, and bringing into safeguards, has commenced.

  • Dounreay 2021 Britain Emerged from the Second World War Intent on Harnessing Nuclear Energy to Power Its Recovery
    Dounreay 2021 Your guide to Scotland's centre of excellence in nuclear decommissioning 2021 Dounreay 2021 Britain emerged from the Second World War intent on harnessing nuclear energy to power its recovery. But uranium was scarce and its use prioritised for weapons production, so the country launched one of its most visionary scientic experiments – to research and develop a new type of power station that would create more fuel than it consumed. Dounreay was chosen as the test site for this new technology of fast breeder nuclear reactors. Over the next 40 years, scientists and engineers proved that plutonium could be harvested from a reactor and recovered in adjacent chemical works to create new fuel to generate electricity. 1 2021 As the 20th century drew to a close, and uranium prices continued to fall, the economics of electricity from plutonium became uncompetitive and the UK Government withdrew from the technology. Today, after leading the world for four decades in research and development of nuclear technology, Dounreay is again at the forefront of science and engineering – this time in the skills and innovation needed to dismantle one of the most complex and hazardous legacies of the 20th century. Dounreay today is a site of major construction, demolition and waste management. The experimental facilities are being cleaned out and knocked down, and the environment is being made safe for future generations. 2 2021 The story so far 1954 1955 1955 1955 1956 UK Government selects wartime aireld UK Atomic Energy Authority begins Craft
