This book was released on 1999 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Storage of aluminum-clad spent nuclear fuel at the Savannah River Site (SRS) and other locations in the U.S. and around the world has been a concern over the past decade because of the long time interim storage requirements in water. Pitting corrosion of production aluminum-clad fuel in the early 1990''s at SRS was attributed to less than optimum quality water and corrective action taken has resulted in no new pitting since 1994. The knowledge gained from the corrosion surveillance testing and other investigations at SRS over the past 8 years has provided an insight into factors affecting the corrosion of aluminum in relatively high purity water. This paper reviews some of the early corrosion issues related to aluminum-clad spent fuel at SRS, including fundamentals for corrosion of aluminum alloys. It updates and summarizes the corrosion surveillance activities supporting the future storage of over 15,000 research reactor fuel assemblies from countries over the world during the next 15-20 years. Criteria are presented for providing corrosion protection for aluminum-clad spent fuel in interim storage during the next few decades while plans are developed for a more permanent disposition.

This book was released on 2003 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes research performed in ten laboratories within the framework of the IAEA Co-ordinated Research Project on Corrosion of Research Reactor Aluminium Clad Spent Fuel in Water. The project consisted of exposure of standard racks of corrosion coupons in the spent fuel pools of the participating research reactor laboratories and evaluation of the coupons after predetermined exposure times, along with periodic monitoring of the storage water. A group of experts in the field contributed a state of the art review and provided technical supervision of the project. Localized corrosion mechanisms are notoriously difficult to understand, and it was clear from the outset that obtaining consistency in the results and their interpretation from laboratory to laboratory would depend on the development of an excellent set of experimental protocols. These experimental protocols are described in the report, together with guidelines for the maintenance of optimum water chemistry to minimize the corrosion of aluminium clad research reactor fuel in wet storage.

Available in PDF, EPUB and Kindle. Book excerpt: Spent nuclear fuels from foreign and domestic research and test reactors are being returned to the Savannah River Site for storage with other nuclear materials in the L-Basin. Recent efforts have consolidated the fuel storage systems and L-Basin has become the SRS site for wet storage of spent nuclear fuels. Corrosion surveillance of coupons in this basin is being performed to provide assurance of safe storage of spent fuel. This paper describes the highlights of recent studies on these aluminum coupons after immersion for more than 7 years in L-Basin. Selected coupons were metallurgically characterized to establish the existence of general corrosion and pitting. Minor pitting corrosion was observed on the intentionally galvanically coupled samples and creviced coupons, thus demonstrating that localized concentration cells were formed during the exposure period. In these cases, the susceptibility to pitting was not attributed to aggressive basin water chemistry but to localized conditions--crevices and galvanic coupling--that allowed the development of oxygen and/or metal ion concentration cells that produced locally aggressive waters. General corrosion was also observed on some of the coupons. None of the coupons were pre-oxidized to form a protective oxide as compared to the spent fuel which was oxidized during reactor operations. This enables the coupons to react to basin water chemistry in a relatively short period of time whereas spent fuel is protected against such reactions. The coupon observations demonstrate that, even when the basin water chemistry is rigorously controlled, localized aggressive conditions can develop, emphasizing the importance of a routine surveillance program.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Aluminum-clad spent nuclear fuel will be transported for processing in the 70-ton nuclear fuel element cask from L Basin to H-canyon. During transport these fuels would be expected to experience high temperature aqueous corrosion from the residual L Basin water that will be present in the cask. Cladding corrosion losses during transport were calculated for material test reactor (MTR) and high flux isotope reactors (HFIR) fuels using literature and site information on aqueous corrosion at a range of time/temperature conditions. Calculations of the cladding corrosion loss were based on Arrhenius relationships developed for aluminum alloys typical of cladding material with the primary assumption that an adherent passive film does not form to retard the initial corrosion rate. For MTR fuels a cladding thickness loss of 33 % was found after 1 year in the cask with a maximum temperature of 260 °C. HFIR fuels showed a thickness loss of only 6% after 1 year at a maximum temperature of 180 °C. These losses are not expected to impact the overall confinement function of the aluminum cladding.

Download or read book Radiochemistry and Nuclear Chemistry written by Gregory Choppin and published by Elsevier. This book was released on 2016-01-26 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear chemistry comprises isotope chemistry, radiochemistry, radiation chemistry and nuclear reaction chemistry, along with applications. These interrelated fields are all covered in this textbook for chemists and chemical engineers. This new editionof the standard work 'Nuclear Chemistry' has been completely rewritten and restructured to suit teaching and learning needs in a wide range of chemistry courses, such as basic courses in radiochemistry, or more advanced nuclear chemistry courses.The book is divided into sections that closely fit teaching demands. The first chapter gives a broad introduction and background to the subject, and the second chapter covers stable isotopes. Chapters 3 to 9 comprise what is generally regarded as'radiochemistry'. Chapters 10 to 17 offer a course in nuclear reaction chemistry. Chapter 18 deals with biological radiation effects for the chemist. The last four chapters give a guide to nuclear energy: energy production, fuel cycle, waste management,the largest applied field of nuclear chemistry. Over 200 exercises, with model answers, remain largely unchanged from the first edition, so teachers working from the earlier text should find only advantages in switching to this new restructured coursebook on all aspects of nuclear chemistry. 'The book fully meets the authors objectives, it is well written in a logical, objective, thought-provoking and quite easily readable style. It should appeal to the serious student of radio- and nuclearchemistry at either undergraduate or postgraduate level, as well as to readers with a more general interest in nuclear science and its impact on the environment.' - Applied Radiation and Isotopes, July 1995 'This book is an excellent, readable accountof a significant part of the scientific achievements of more than half this century. The authors have dedicated the book to Nobel Laureate Glenn T. Seaborg and its scholarship makes it a fitting tribute.' - Radiological Protection Bulletin, December 1995

Available in PDF, EPUB and Kindle. Book excerpt: This publication is a revision by amendment of IAEA Safety Standards Series No. SSG-15 and provides recommendations and guidance on the storage of spent nuclear fuel. It covers all types of storage facility and all types of spent fuel from nuclear power plants and research reactors. It takes into consideration the longer storage periods beyond the original design lifetime of the storage facility that have become necessary owing to delays in the development of disposal facilities and the reduction in reprocessing activities. It also considers developments associated with nuclear fuel, such as higher enrichment, mixed oxide fuels and higher burnup. Guidance is provided on all stages in the lifetime of a spent fuel storage facility, from planning through siting and design to operation and decommissioning. The revision was undertaken by amending, adding and/or deleting specific paragraphs addressing recommendations and findings from studying the accident at the Fukushima Daiichi nuclear power plant in Japan.
