This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims to investigate sites where corrosion initiates on an austenitic stainless steel used to encapsulate advanced gas-cooled nuclear reactor fuel when in long term pond storage and subsequently provide insight into what happens when corrosion propagates. The combination of both a critical temperature and radiation dose within the reactor core may lead to very small quantities of this stainless steel becoming sensitised. The first chapter is a discussion on the literature and past study on the subject. Within the second chapter, analysis of the stainless steel in an as-received format is undertaken, and is relevant, given that only a very small quantity of cladding may be rendered sensitised. This chapter includes an investigation into Cl- concentration and temperature dependence.The third chapter focuses on identifying the initiation points of localised intergranular corrosion (IGC) in freely corroding and perturbed environments. An in-situ time-lapse microscopy and scanning vibrating electrode technique investigation are used in conjunction with post corrosion microscopy to study areas affected by IGC. The fourth chapter describes a higher resolution approach to investigating the initiation point of IGC. A scanning Kelvin probe force microscope is used to map the surfaces for areas in which corrosion may occur, while an atomic force microscope was used to provide high resolution images of tens of grains undergoing in-situ IGC. The aim of the final chapter is to provide an insight into reducing corrosion rates using an NaOH pre-treatment. NaOH is used in two different concentrations to study the effect on the free corrosion and breakdown potentials (Ecorr and Eb) on as-received and sensitised 20/25/Nb.This study will provide a scientic backbone that the industry may use to target areas of further research, helping provide ongoing safe storage of spent nuclear fuel in the UK.

Download or read book The Corrosion of Aluminum clad Spent Nuclear Fuel in Wet Basin Storage written by and published by . This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Large quantities of Defense related spent nuclear fuels are being stored in water basins around the United States. Under the non-proliferation policy, there has been no processing since the late 1980's and these fuels are caught in the pipeline awaiting stabilization or other disposition. At the Savannah River Site, over 200 metric tons of aluminum clad fuel are being stored in four water filled basins. Some of this fuel has experienced visible pitting corrosion. An intensive effort is underway at SRS to understand the corrosion problems and to improve the basin storage conditions for extended storage requirements. Significant improvements have been accomplished during 1993-1996. This paper presents a discussion of the fundamentals of aluminum alloy corrosion as it pertains to the wet storage of spent nuclear fuel. It examines the effects of variables on corrosion in the storage environment and presents the results of corrosion surveillance testing activities at SRS, as well as discussions of fuel storage basins at other production sites of the Department of Energy.

Book excerpt: The factors affecting the optimal water chemistry of the Savannah River Site spent fuel storage basin must be determines in order to optimize facility efficiency, minimize fuel corrosion, and reduce overall environmental impact from long term spent nuclear fuel storage at the Savannah River Site. The Savannah River National Laboratory is using statistically designed experiments to study the effects of NO3−, SO42−, and Cl− concentrations on alloys commonly used not only as fuel cladding, but also as rack construction materials The results of cyclic polarization pitting and corrosion experiments on samples of Al 6061 and 1100 alloys will be used to construct a predictive model of the basin corrosion and its dependence on the species in the basin. The basin chemistry model and corrosion will be discussed in terms of optimized water chemistry envelope and minimization of cladding corrosion.

This book was released on 2006-09-12 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: DOE Tank Waste: How clean is clean enough? The U.S. Congress asked the National Academies to evaluate the Department of Energy's (DOE's) plans for cleaning up defense-related radioactive wastes stored in underground tanks at three sites: the Hanford Site in Washington State, the Savannah River Site in South Carolina, and the Idaho National Laboratory. DOE plans to remove the waste from the tanks, separate out high-level radioactive waste to be shipped to an off-site geological repository, and dispose of the remaining lower-activity waste onsite. The report concludes that DOE's overall plan is workable, but some important challenges must be overcomeâ€"including the removal of residual waste from some tanks, especially at Hanford and Savannah River. The report recommends that DOE pursue a more risk-informed, consistent, participatory, and transparent for making decisions about how much waste to retrieve from tanks and how much to dispose of onsite. The report offers several other detailed recommendations to improve the technical soundness of DOE's tank cleanup plans.
Download or read book Decommissioning of Pools in Nuclear Facilities written by International Atomic Energy Agency and published by IAEA Nuclear Energy. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pools or ponds are usually an integrated part of a more complex nuclear facility, but in some particular cases pools may be considered as a separate nuclear facility with a specific license. A number of nuclear installations utilize pools for the cooling of spent fuel, or the shielding of research reactor cores or irradiator sources. Over a service lifetime that can span decades, nuclear pools may become contaminated as a result of the deposition of radioactive substances. Relevant aspects of pool decommissioning covered in this publication include project planning and management, health and safety, and the management of resulting waste.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book discusses the eroding economics of nuclear power for electricity generation as well as technical, legal, and political acceptance issues. The use of nuclear power for electricity generation is still a heavily disputed issue. Aside from technical risks, safety issues, and the unsolved problem of nuclear waste disposal, the economic performance is currently a major barrier. In recent years, the costs have skyrocketed especially in the European countries and North America. At the same time, the costs of alternatives such as photovoltaics and wind power have significantly decreased.
