Scotland, Nuclear Energy Policy and Independence Raphael J. Heffron
Scotland, Nuclear Energy Policy and Independence EPRG Working Paper 1407 Cambridge Working Paper in Economics 1457 Raphael J. Heffron and William J. Nuttall Abstract This paper examines the role of nuclear energy in Scotland, and the concerns for Scotland as it votes for independence. The aim is to focus directly on current Scottish energy policy and its relationship to nuclear energy. The paper does not purport to advise on a vote for or against Scottish independence but aims to further the debate in an underexplored area of energy policy that will be of value whether Scotland secures independence or further devolution. There are four central parts to this paper: (1) consideration of the Scottish electricity mix; (2) an analysis of a statement about nuclear energy made by the Scottish energy minister; (3) examination of nuclear energy issues as presented in the Scottish Independence White Paper; and (4) the issue of nuclear waste is assessed. A recurrent theme in the analysis is that whether one is for, against, or indifferent to new nuclear energy development, it highlights a major gap in Scotland’s energy and environmental policy goals. Too often, the energy policy debate from the Scottish Government perspective has been reduced to a low-carbon energy development debate between nuclear energy and renewable energy. There is little reflection on how to reduce Scottish dependency on fossil fuels. For Scotland to aspire to being a low-carbon economy, to decarbonising its electricity market, and to being a leader within the climate change community, it needs to tackle the issue of how to stop the continuation of burning fossil fuels. -

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.

AREVA and MHI Agree on Collaboration in Nuclear Energy - Memorandum of Understanding Signed in Tokyo
AREVA and MHI Agree on Collaboration in Nuclear Energy - Memorandum of Understanding Signed in Tokyo - 2006-10-19 AREVA Group Mitsubishi Heavy Industries, Ltd Tokyo, October 19, 2006 -AREVA, the world's largest business group in the nuclear energy field, and Mitsubishi Heavy Industries, Ltd. (MHI) have agreed to collaborate in the area of nuclear energy, according to a memorandum of understanding signed today in Tokyo by Anne Lauvergeon, CEO of AREVA, and Kazuo Tsukuda, President of MHI. The "nuclear renaissance" has brought about new challenges for the whole nuclear industry, as growth and new expectations of clients require significant mobilization of large financial and human resources. Facing the tremendous market changes, AREVA and MHI have decided to establish a powerful and ground-breaking alliance built on their historical successful relationship* and respective human and industrial capabilities. As a first step, the two companies have already agreed to develop a 3rd-generation 1,000 MWe nuclear power plant expected to attract great market demand. The agreement covers other fields of possible cooperation such as procurement, services, fuel cycle and new types of reactors. AREVA CEO Anne Lauvergeon noted, "This alliance has been worked out on the ground of mutual trust and common vision. Our technical innovation capabilities and our geographical complementarities will bring to our clients, in the field of nuclear power plants and services, unequalled solutions." MHI President Kazuo Tsukuda stated, "We at MHI are all excited about this collaboration with AREVA. It will enable to provide the nuclear power plant technologies and experience accumulated by the two companies around the world in nuclear power generation. -
Waiting for the Nuclear Renaissance: Exploring the Nexus of Expansion and Disposal in Europe
Risk, Hazards & Crisis in Public Policy www.psocommons.org/rhcpp Vol. 1: Iss. 4, Article 3 (2010) Waiting for the Nuclear Renaissance: Exploring the Nexus of Expansion and Disposal in Europe Robert Darst, University of Massachusetts-Dartmouth Jane I. Dawson, Connecticut College Abstract This article focuses on the growing prospects for a nuclear power renaissance in Europe. While accepting the conventional wisdom that the incipient renaissance is being driven by climate change and energy security concerns, we argue that it would not be possible without the pioneering work of Sweden and Finland in providing a technological and sociopolitical solution to the industry’s longstanding “Achilles’ heel”: the safe, permanent, and locally acceptable disposal of high-level radioactive waste. In this article, we track the long decline and sudden resurgence of nuclear power in Europe, examining the correlation between the fortunes of the industry and the emergence of the Swedish model for addressing the nuclear waste problem. Through an in-depth exploration of the evolution of the siting model initiated in Sweden and adopted and successfully implemented in Finland, we emphasize the importance of transparency, trust, volunteerism, and “nuclear oases”: locations already host to substantial nuclear facilities. Climate change and concerns about energy independence and security have all opened the door for a revival of nuclear power in Europe and elsewhere, but we argue that without the solution to the nuclear waste quandary pioneered by Sweden and Finland, the industry would still be waiting for the nuclear renaissance.

After Years of Stagnation, Nuclear Power Is On
5 Vaunted hopes Climate Change and the Unlikely Nuclear Renaissance joshua William Busby ft er years oF s TaGNaTioN, Nucle ar P oWer is oN The atable again. Although the sector suffered a serious blow in the wake of the Fukushima Daiichi nuclear meltdown that occurred in Japan in early 2011, a renewed global interest in nuclear power persists, driven in part by climate concerns and worries about soaring energy demand. As one of the few relatively carbon-free sources of energy, nuclear power is being reconsid- ered, even by some in the environmental community, as a possible option to combat climate change. As engineers and analysts have projected the poten- tial contribution of nuclear power to limiting global greenhouse gas emis- sions, they have been confronted by the limits in efficiency that wind, water, and solar power can provide to prevent greenhouse gas emissions from rising above twice pre-industrial levels. What would constitute a nuclear power renaissance? In 1979, at the peak of the nuclear power sector’s growth, 233 power reactors were simultaneously under construction. By 1987, that number had fallen to 120. As of February 2012, 435 nuclear reactors were operable globally, capable of producing roughly 372 gigawatts (GW) of electricity (WNA 2012). Some analysts suggest that, with the average age of current nuclear plants at twenty-four years, more than 170 reactors would need to be built just to maintain the current number in 2009 1 Copyright © 2013.

The Nuclear Renaissance and AREVA's Reactor Designs for the 21 Century: EPR and SWR-1000
The Nuclear Renaissance and AREVA’s Reactor Designs for the 21st Century: EPR and SWR-1000 Zoran V. STOSIC AREVA NP Koldestr. 16, 91052 Erlangen, Germany [email protected] ABSTRACT Hydro and nuclear energy are the most environmentally benign way of producing electricity on a large scale. Nuclear generated electricity releases 38 times fewer greenhouse gases than coal, 27 times fewer than oil and 15 times fewer than natural gas [9]. On a global scale nuclear power annually saves about 10% of the global CO2 emission. European nuclear power plants save amount of CO2 emissions corresponding with the annual emission of CO2 from all European passenger cars [16]. Also, that is approximately twice the total estimated quantity to be avoided in Europe under the Kyoto Protocol during the period 2008–2012. In respect to main drivers – such as concerns of the global warming effect, population growth, and future energy supply shortfall, low operating costs, reduced dependence on imported gas – it is clear that 30 new nuclear reactors currently being constructed in 11 countries and another 35 and more planed during next 10 years confirm the nuclear renaissance. Participation in the construction of 100 reactors out of 443 worldwide operated in January 2006 and supplying fuel to 148 of them AREVA helps meet the 21st century’s greatest challenges: making energy available to all, protecting the planet, and acting responsibly towards future generations. With EPR and SWR- 1000, AREVA NP has developed advanced design concepts of Generation III+ nuclear reactors which fully meet the most stringent requirements in terms of nuclear safety, operational reliability and economic performance. -

Reactor Types[Edit]
methods of control of rate of fusion reaction The only known way to control a fusion reaction is with an extremely strong and shaped/focused magnetic field. With today's technology we cannot yet make it strong enough. It breaks up in milliseconds after the reaction, stopping the reaction. types of nuclear materials Nuclear material refers to the metals uranium, plutonium, and thorium, in any form, according to the IAEA. This is differentiated further into "source material", consisting of natural and depleted uranium, and "special fissionable material", consisting of enriched uranium (U- 235), uranium-233, and plutonium-239. fissile and fertile materials Fertile material Fertile material is a material that, although not itself fissionable by thermal neutrons, can be converted into a fissile material by neutron absorption and subsequent nuclei conversions In nuclear engineering, fertile material (nuclide) is material that can be converted to fissile material by neutron. Nuclear reactors elements A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self- sustained nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. Heat from nuclear fission is passed to a working fluid (water or gas), which in turn runs through steam turbines. These either drive a ship's propellers or turn electrical generators' shafts. Nuclear generated steam in principle can be used for industrial process heat or for district heating. Some reactors are used to produce isotopes for medical and industrial use, or for production of weapons-grade plutonium. As of early 2019, the IAEA reports there are 454 nuclear power reactors and 226 nuclear research reactors in operation around the world. -
