Esta es la historia de una España que pudo haber sido y no fue. ¿La razón? La indecisión de quien tuvo que autorizar que contase con su propia fuerza de disuasión nuclear, con lo que se hubiera ganado el respeto de todos y el temor de algunos, pero sobre todo que hubiera propiciado ulteriores logros cientificos y tecnologicos. Y todo ello sucedio cuando ya se habia concluido el proyecto y desarrollado algunos de los componentes de una bomba atomica de plutonio.Guillermo Velarde, autor de esta obra con la valiosa colaboracion de Natividad Carpintero y director del citado proyecto, llevo a cabo posteriormente un dificil y complejo trabajo de investigacion que le permitio en 1966 redescubrir el metodo Ulam-Teller base de las verdaderas bombas termonucleares, gestado en 1952 por Stanislaw Ulam y Edward Teller en los Estados Unidos. En 1954, Andrei Sajarov lo redescubriria en la URSS y, en 1966, Robert Dautray en Francia y P. Huanwu en China lo harian asimismo, con trascendentes consecuencias para sus paises. España hubiera sido entonces el quinto pais del mundo con capacidad para desarrollar bombas termonucleares. A pesar de todo, Franco decidio posponer indefinidamente el Proyecto. Cientifica a la vez que autobiografica, Proyecto Islero es una reveladora obra que aborda la evolucion cientifica en nuestro pais durante el pasado siglo, y que narra como España pudo llegar a ser una potencia nuclear pero desistio de ello en el ultimo momento, evitando asi que nuestro pais alcanzara un desarrollo tecnologico que hubiera supuesto un punto de inflexion de magnitudes historicas.

Una visión global del problema energético y de la necesidad de reabrir el debate sobre la energía nuclear.El futuro de la energía es uno de los mayores retos del siglo XXI. Los combustibles fósiles se acaban y son muy contaminantes, las energias renovables aun estan en desarrollo y la controvertida energia nuclear vive en el alambre: esta sujeta a una moratoria en paises como España o Alemania, se ha prohibido en algunos y es clave en otros como Francia y Suecia.Lozano Leyva se enfrenta, con este libro, a los prejuicios que a menudo impiden un debate sereno e informado, y nos habla de la energia nuclear sin eludir sus aspectos mas espinosos: su historia, su papel en la naturaleza, su uso militar y pacifico, los problemas de residuos, seguridad, contaminacion y proliferacion. Es un libro que no esta a favor ni en contra de la energia nuclear, sino que defiende la necesidad de informacion veraz a fin de que cada uno pueda tener su propia opinion en una cuestion clave para nuestras sociedades.Reseña: Uno de nuestros mejores cerebros.ABC

The role of organizational culture in international efforts to stop the spread of nuclear weapons.In Transforming Nuclear Safeguards Culture, Trevor Findlay investigates the role that organizational culture may play in preventing the spread of nuclear weapons, examining particularly how it affects the nuclear safeguards system of the International Atomic Energy Agency (IAEA), the paramount global organization in the non-proliferation field. Findlay seeks to identify how organizational culture may have contributed to the IAEAs failure to detect Iraqs attempts to acquire illicit nuclear capabilities in the decade prior to the 1990 Gulf War and how the agency has sought to change safeguards culture since then. In doing so, he addresses an important piece of the nuclear nonproliferation puzzle: how to ensure that a robust international safeguards system, in perpetuity, might keep non-nuclear states from acquiring such weapons. Findlay, as one of the leading scholars on the IAEA, brings a valuable holistic perspective to his analysis of the agencys culture. Transforming Nuclear Safeguards Culture will inspire debate about the role of organizational culture in a key international organizationa culture that its member states, leadership, and staff have often sought to ignore or downplay.

Sitting near four significant fault lines on the coastline of California, Diablo Canyon is just one of 65 nuclear power plants in the United States. After the nuclear meltdown in Fukushima, Japan, Americans are now asking, "Could it happen here?"This e-book original, based on an in-depth investigation commissioned exclusively for Prevention magazine by the award-winning photojournalist team of Chanan Tigay and Colin Finlay, explores the risks--to our planet and ourselves--of the plant and its impact on the people who live and work in the "happiest place in America."

Chaque année on produit de grandes quantités de déchets dangereux, mais seule une faible proportion est constituée de déchets radioactifs. Si, globalement, on a trouvé des solutions satisfaisantes pour la gestion des dechets dangereux, certaines categories posent des problemes analogues au stockage des dechets radioactifs et exigent aussi un stockage de longue duree. Avec cette etude, lAEN entend mettre en perspective la gestion des dechets radioactifs, dabord par une comparaison des caracteristiques entre dechets radioactifs et dangereux et les politiques et strategies de gestion qui leur sont appliquees, puis a travers lanalyse du cas particulier des dechets provenant du captage et du stockage du carbone issu de combustibles fossiles. Il sagit ainsi de fournir aux decideurs une vue densemble des similitudes et differences entre les dechets radioactifs et dangereux et leurs strategies de gestion.

Avec la construction de centrales nucléaires dans plusieurs pays et des projets de construction additionnels pour répondre à la demande croissante d’électricité, les ressources en uranium, sa product

Large volumes of hazardous wastes are produced each year, however only a small proportion of them are radioactive. While disposal options for hazardous wastes are generally well established, some types of hazardous waste face issues similar to those for radioactive waste and also require long-term disposal arrangements. The objective of this NEA study is to put the management of radioactive waste into perspective, firstly by contrasting features of radioactive and hazardous wastes, together with their management policies and strategies, and secondly by examining the specific case of the wastes resulting from carbon capture and storage of fossil fuels. The study seeks to give policy makers and interested stakeholders a broad overview of the similarities and differences between radioactive and hazardous wastes and their management strategies.

With several countries currently building nuclear power plants and planning the construction of more to meet long-term increases in electricity demand, uranium resources, production and demand remain topics of notable interest. In response to the projected growth in demand for uranium and declining inventories, the uranium industry the first critical link in the fuel supply chain for nuclear reactors is boosting production and developing plans for further increases in the near future. Strong market conditions will, however, be necessary to trigger the investments required to meet projected demand.The Red Book, jointly prepared by the OECD Nuclear Energy Agency and the International Atomic Energy Agency, is a recognised world reference on uranium. It is based on information compiled in 40 countries, including those that are major producers and consumers of uranium. This 23rd edition provides a comprehensive review of world uranium supply and demand as of 1 January 2009, as well as data on global uranium exploration, resources, production and reactor-related requirements. It provides substantive new information from major uranium production centres around the world, as well as from countries developing production centres for the first time. Projections of nuclear generating capacity and reactor-related uranium requirements through 2035 are also featured, along with an analysis of long-term uranium supply and demand issues.

Hydrogen has the potential to play an important role as a sustainable and environmentally acceptable energy carrier in the 21st century. This report describes the scientific and technical challenges associated with the production of hydrogen using heat and/or electricity from nuclear power plants, with special emphasis on recent developments in high-temperature electrolysis and the use of different chemical thermodynamic processes. Economics and market analysis as well as safety aspects of the nuclear production of hydrogen are also discussed.

These workshop proceedings highlight the significant amount of work accomplished over the past decade in delivering transparent, proportionate regulation for geological disposal, and identify important differences between national regulations even if these are not in contradiction with international guidance. They also underline the importance of R&D carried out on behalf of the regulator. In addition to the contributed papers, these proceedings trace the numerous discussions that formed an integral part of the workshop. They constitute an important and unique documentary basis for researchers and radioactive waste management specialists. Themes addressed include duties to future generations, timescales for regulation, stepwise decision making, roles of optimisation and best available techniques (BAT), multiple lines of reasoning, safety and performance indicators, recognition of uncertainties and the importance of stakeholder interactions.

Le renouveau dintérêt pour lénergie nucléaire résultant des préoccupations causées par le changement climatique global et la sécurité dapprovisionnement, qui est susceptible dentraîner une croissance

The renewed interest in nuclear energy triggered by concerns about global climate change and security of supply could lead to substantial growth in nuclear electricity generation and expanded interest in fast neutron reactors with closed fuel cycles. Moving from the current fleet of thermal neutron reactors to fast neutron systems will require many decades and extensive RD&D efforts. This book identifies and analyses key strategic and policy issues raised by such a transition, and provides guidance to decision makers on the best approaches for implementing transition scenarios.

Geological settings selected as potential host formations for the deep geological disposal of radioactive waste are chosen for, among other assets, their long-term stability and buffering capacity against destabilising events and processes. These proceedings present the outcomes of a geosphere stability workshop, held in November 2007, that focused on crystalline and other types of hard, fractured rocks. The workshop underscored the fact that many such rocks are intrinsically stable environments that evolve extremely slowly and provide good buffering against external events and processes.The proceedings show a good understanding of the processes and events that can affect crystalline rocks and, although there is less confidence in predicting exactly when and where such events will occur and the volume of rock that will be affected, the extent of the impacts on a geological repository can be confidently addressed using bounding approaches supported by geological information from similar sites around the world.
