This publication is a compilation of the main results and findings of an IAEA coordinated research project (CRP). In particular, it discusses an innovative variation of neutron activation analysis (NAA) known as large sample NAA (LSNAA). There is no other way to measure the bulk mass fractions of the elements present in a large sample (up to kilograms in mass) non-destructively. Examples amenable to LSNAA include irregularly shaped archaeological artefacts, excavated rock samples, large samples of assorted ore, and finished products, such as nuclear reactor components. Advantages of LSNAA applications, limitations and scientific and technological requirements are described in this publication, which serves as a reference of interest not only to the NAA experts, research reactor personnel, and those considering this technique, but also to various stakeholders and users such as researchers, industrialists, environmental and legal experts, and administrators.

Seismic isolation technology has the potential to significantly reduce the overall risk posed by earthquake ground motions to nuclear power plants. A testing programme is an integral part of a seismic isolation project. Not only must the isolating devices be characterized for design purposes, but also validation of the analytical procedures used in design is required. Hybrid simulation is a testing technique which is a good candidate to experimentally assess the behaviour of an isolation system. The method combines the computation of the response of the isolated structure with the experimental determination of the behaviour of full-scale isolators under the demand imposed by the movement of ground and structure. This publication contributes to the assessment of the method as a tool for the design and safety demonstration of base-isolated nuclear facility buildings.

Almost from the moment in 1940 that Otto Frisch and Rudofl Peierls suggested, from their small office in the University of Birmingham, that an atomic weapon could be miniaturized and delivered to its target by aircraft, the concept of atomic espionage can be said to have existed. No sooner had the famous Frisch-Peierls Memorandum been received by the British War Cabinet than a Soviet mole, John Cairncross, passed the details on to his Soviet contact. And 70 years later with the International Atomic Energy Authority (IAEA) estimating that up to 40 countries now have the capability of building nuclear weapons, the need to monitor this activity remains crucial. The Historical Dictionary of Atomic Espionage relates the history of atomic espionage through a chronology, an introductory essay, and cross-referenced dictionary entries on the agencies, agents, and operations. This book is an excellent access point for students, researchers, and anyone wanting to know more about atomic espionage.

Following the acquisition of the atomic bomb by five states, the United Nations began drafting several treaties to limit nuclear proliferation. These efforts failed, as four more states also acquired nuclear weapons. In a similar vein, an attempt to limit atomic weapons - primarily within the two superpowers - was initiated.While the number of weapons has decreased, the new bombs now being manufactured are more powerful and more precise, negating any reduction in numbers. In the field of civil nuclear use, all nuclear facilities (reactors, factories, etc.) have a limited lifespan. Once a plant is permanently shut down, these facilities must be decommissioned and dismantled.These operations are difficult, time-consuming and costly. In addition, decommissioning generates large volumes of radioactive waste of various categories, including long-lived and high-activity waste. Risks to the environment and to health are not negligible during decommissioning. The International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency (NEA) of the Organisation for Economic Co-operation and Development (OECD) have produced numerous publications with recommendations. Each state has its own decommissioning strategy (immediate or delayed) and final plan for the site - whether it be returning it to greenfield status or obtaining a nuclear site license with centuries-long monitoring.

Armageddon is a contemporary epic poem about the major event of our own time. Written in blank verse, it narrates the defining event for civilisation today: the American President Bush's struggle against the Islamic extremism of Osama bin Laden and al-Qaeda, in the course of which Bush transforms himself, the US and the world. It follows the War on Terror from September 11, 2001 through the wars in Afghanistan and Iraq, which some believe were illegally waged for reasons of oil. Covertly supported by Iran, bin Laden is shown as possessing at least 20 nuclear suitcase bombs (a purchase confirmed by Hans Blix of the IAEA in 2004), some of which he plans to explode simultaneously in 10 American cities - hence the title. The poem presents all sides of the War on Terror and makes sense of the first decade of the 21st century. Armageddon is Nicholas Hagger's second poetic epic. It is the successor to his Overlord, which was the first major poetic epic in the English language since Milton's Paradise Lost. Overlord was about the Second World War from D-Day to the dropping of the atomic bomb and also followed an American hero, Eisenhower. Like Overlord, Armageddon is also in the tradition of Homer's Iliad and Virgil's Aeneid, and its epic sweep includes higher and lower worlds in the Universalist manner. Both qualify as American epics, though written by an English poet. The only other poet to have written two major poetic epics is Homer.

The year 2018 marked the 90th anniversary of induced mutagenesis in plants. The FAO/IAEA International Symposium on Plant Mutation Breeding and Biotechnology held in 2018 reviewed achievements in crop improvement through mutation breeding in several countries across the globe, and discussed innovations in mutation induction, precision phenotyping and genomics applications. Induced genetic variation is important for crop improvement especially in instances where there is limited variation in existing germplasm pools to achieve desired levels of crop performance, and where techniques such as hybridization cannot be easily applied. Its application becomes further significant as the dual threats of population growth and climate change increasingly challenge global food and nutrition security. Higher production of nutritional food and reduction of crop losses imposed by extreme events like droughts, high temperatures, floods, diseases and pests call for induced novel genetic variation. While recent breakthroughs in whole genome-based mutation detection technologies increase the efficiency and precision of breeding in all crops, in vitro techniques coupled with mutagenesis broaden the genetic base of vegetative and horticultural tree crops and reduce their breeding cycles. In this book an international team of expert authors review achievements, new developments, trends and challenges in the field of plant mutation breeding, across the scientific community and the private sector. Chapters highlight specific challenges, such as emerging transboundary threats to crop production, and assess the overall importance of mutation breeding to food security. Coverage includes: · Contribution and impact of mutant varieties to food security. · Mutation breeding for adaptation to climate change in seed propagated crops. · Mutation breeding for ornamental and vegetatively propagated crops. · Enhancing agro biodiversity through new mutation induction techniques. · New challenges and technologies in plant genomics and breeding. This book is a comprehensive and essential resource for students, researchers and professionals in plant breeding.

The Iranian regime is in the midst of a dangerous nuclear poker game with the West, playing for the highest possible stakes. Iran, ruled today by Ali Khamenei, the Guide of the Revolution, and the recently elected President Ahmadinejad, has no intention of yielding to international pressure exhorting it to suspend all uranium enrichment activity, a necessary but intermediate step in the process of building nuclear weapons. Iran is also seeking to join the WTO and it had been offered this incentive by the United States and the EU '3' (France, Britain and Germany) in exchange for a promise to cease enrichment. However, President Ahmadinejad's 12 April announcement that Iran has successfully enriched uranium takes the crisis to a higher plane. It also leaves many questions unanswered, above all, how the international community should respond to this unwelcome development. In this hard-hitting analysis of Tehran's intentions, Therese Delpech, one of the world's leading authorities on international nuclear security, outlines how Iran has successfully beguiled the international community for years, aided and abetted by China and Russia, both of which are eager to benefit commercially from Iran acquiring nuclear power. She dissects Iran's nuclear programme in minute detail, drawing on her inside knowledge. The first section of the book retraces the history of Iran's nuclear project from the 1970s -- one that was launched by the former Shah with help from several Western countries -- till today, when national pride, exemplified by Ahmadinejad's bellicose rhetoric, makes it highly unlikely that Tehran will bow to the diktats of the international community. She also examines the period when the programme was resumed, during Iran's war with Iraq (1985-90). The second section picks apart the strategy of the various actors in this global crisis: Iran, the EU '3', the United States, Russia, China and the IAEA (the International Atomic Energy Agency). In the third section, she sets out the various possible solutions in terms of their feasibility, practically and politically: dismantling by force, supervised third party reprocessing, referral to the Security Council, Iranian appeasement. In conclusion, Delpech unravels the tangled regional and international dimensions of the crisis, setting out the enormous impact it is having on the Persian Gulf, Turkey, Israel, America's presence in Iraq and the wider Middle East and the future of the much weakened Nuclear Non-Proliferation Treaty (NTP).
