Nuclear Power

In this book, the author provides a deep study into multiscale and multiphysics modeling of nuclear facilities, underscoring the critical role of uncertainty quantification and sensitivity analysis to ensure the confidence in the numerical results and to identify the system characteristics. Through an in-depth study of the liquid metal cooling system from the TALL-3D loop to the SMDFR core, the research highlights the natural circulation instability, strong coupling effects, perturbation tolerance, and system stability. The culmination of the research is the formulation of an optimized uncertainty-based control scheme, demonstrating its versatility beyond the nuclear domain to other energy sectors. This groundbreaking work not only advances the comprehension and utilization of coupling schemes and uncertainty methodologies in nuclear system modeling but also adeptly bridges the theoretical constructs with tangible application, positioning itself as an indispensable resource for design, safety analysis, and advanced numerical modeling in the broader energy sector.

Reliability and safetyare core issues that must be addressed throughout the life cycle of engineeringsystems. Reliability and Safety Engineering presents an overview of the basicconcepts, together with simple and practical illustrations.The authors presentreliability terminology in various engineering fields, viz., electronicsengineering, software engineering, mechanical engineering, structuralengineering and power systems engineering. The book describes the latestapplications in the area of probabilistic safety assessment, such as technicalspecification optimization, risk monitoring and risk informed in-serviceinspection. Reliability and safety studies must, inevitably, deal withuncertainty, so the book includes uncertainty propagation methods: Monte Carlosimulation, fuzzy arithmetic, Dempster-Shafer theory and probability bounds.Reliability and Safety Engineering also highlights advances in system reliabilityand safety assessment including dynamic system modeling and uncertaintymanagement. Case studies from typical nuclear power plants as well as fromstructural, software and electronic systems are also discussed.Reliability and SafetyEngineering combines discussions of theexisting literature on basic conceptsand applications with state-of-the-art methods used in reliability and riskassessment of engineering systems. It is designed to assist practicingengineers, students and researchers in the areas of reliability engineering andrisk analysis.

THE EURATOM WORKING GROUP ON REACTOR DOSIMETRY AND THE ASTM-EURATOM SYMPOSIA The Euratom Working Group on Reactor Dosimetry (EWGRD) started around 1960 with members having been nominated by the governments, from each European la­ boratory working in reactor physics and technology. The goal was to exchange di­ rectly experience and know-how in reactor dosimetry and related programmes. A need for normalisation was felt in order to guarantee that: the same nuclear data is used; measurements in different laboratories give the same results (need for in­ tercalibration experiments and standards); results are expressed such that a com­ parison with results from other laboratories is possible. In sub-groups, specific arguments were discussed resulting in final recommenda­ tions. These final recommendations were then discussed in a plenary meeting and accepted as a recommendation for European usage. Several of these recommenda­ tions were published, e.g. radiation damage dosimetry guidebooks, and a nuclear data guidebook. Also a programme, executed by the BCMN GEEL, for the produc­ tion and selling of Reference Materials for Neutron Dosimetry is sponsored by the EWGRD. Workshops in the field of radiation damage and on the pressure vessel steels programme in Europe were successfully organised. The group works in close contact with ASTM (American Society for Testing of Mate­ rials). Altogether seven symposia were jointly organized, and held, alternatively in Europe and USA. The next symposium, the eighth, will be organized by ASTM in 1993 in the USA.

This thesis deals with the problem of ion confinement in thermonuclear fusion devices. It is a topic of general interest, as it helps to understand via numerical simulations the ion confinement properties in complex geometries, in order to predict their behavior and maximize the performance of future fusion reactors. The main work carried out in this thesis is the improvement and exploitation of an existing simulation code called ISDEP.  This code solves the so-called ion collisional transport in arbitrary plasma geometry, improving in this sense other existing codes. Additionally, it presents outstanding portability and scalability in distributed computing architectures, such as Grid or Volunteer Computing.The main physical results can be divided into two blocks. First, the study of 3D ion transport in ITER is presented. ITER is the largest fusion reactor (under construction) and most of the simulations so far assume the axis-symmetry of the device. Unfortunately, this symmetry is only an approximation because of the discrete number of magnetic coils used. ISDEP has shown, using a simple model of the 3D magnetic field, how the ion confinement is affected by this symmetry breaking.Secondly, ISDEP has been applied successfully to the study of fast ion dynamics in fusion plasmas. The fast ions, with energies much larger than the thermal energy, are a product of the device¿s heating system. Thus, a numerical predictive tool can be used to improve the heating efficiency. ISDEP has been combined with the FAFNER2 code to study such ions in stellarator (TJ-II, LHD) and tokamak (ITER) geometries. It has also been validated by experimental results. In particular, comparisons with the CNPA diagnostic in the TJ-II stellarator are remarkable.

This Safety Practices publication, a part of the lAEA’s Radioactive Waste Safety Standards (RADWASS) programme, provides guidance on those application of internationally agreed principles for determining those levels of radionuclides in materials below which they can be exempted from regulatory control and can be recycled or reused without any further restriction. lt illustrates a methodology by which practical exempt quantities for the recycle and reuse of these materials may be derived and gives typical exempt values based on a generic assessment.

There is no silver bullet for the climate crisis-but that hasn't stopped people searching. Seizing its chance, the nuclear power industry wants us to believe that theirs is the only technical fix for our deliverance. The public, politicians and the media have been easily swayed.This should come as no surprise. After all, the pro-nuclear PR campaign is richly funded and has an army of lobbyists sowing myths while the industry reaps the rewards of taxpayer-funded subsidies.No To Nuclear calls the industry's bluff. Blasting aside its claims to be safe and green, Linda Pentz Gunter makes the irresistible case that nuclear power is too slow, too expensive, too dangerous and too integrally connected to the nuclear weapons complex, to serve as a rational energy choice.The book also delves into the lives of Indigenous peoples and communities of colour, who have been harmed the most by the nuclear sector, and questions whether the way we devalue nature and the environment is costing us the chance of a genuinely just energy transition.

Wie konnte ein Hochtechnologieland seine zuverlässigste CO2-freie Stromquelle aufgeben - und dafür alle bazahlen lassen?Wie konnte ein Hochtechnologieland seine zuverlässigste CO2-freie Stromquelle aufgeben - und dafür bezahlen alle? Ulrich Gräber, einst Vorstand und später Deutschland-Chef eines der größten Kerntechnik-Unternehmen, nimmt Sie mit hinter die Kulissen von Politik, Medien und Energiekonzernen. Er zeigt, warum nicht der Klimaschutz das Problem ist, sondern eine Energiepolitik, die physikalische Realitäten ignoriert - mit teuren Irrwegen, Industrieabwanderung und wachsender Abhängigkeit von Importen als Folge. Aus der Perspektive eines Verantwortlichen, der Planung, Bau und Betrieb deutscher Kernkraftwerke selbst mitgestaltet hat, erzählt Gräber die ganze Geschichte: vom rasanten Einstieg über politische Kehrtwenden bis zum "Kniefall vor der Unvernunft" - und was jetzt geschehen muss, damit Deutschland wieder zu einer sicheren, bezahlbaren und klimafreundlichen Stromversorgung findet.Dieses Buch ist kein Wutpamphlet, sondern ein faktenreicher, klarer Weckruf - für alle, die Energiepolitik endlich verstehen und mitreden wollen. Wer die Zukunft unseres Wohlstands sichern will, sollte diese Analyse lesen.

The climate crisis has inspired new hope in nuclear energy. Its advocates claim we already have the technology of the future, ready to be perfected and deployed. But as M. V. Ramana argues in this urgent and lucid book, such think­ing is not only naïve but dangerous.<BR><BR>Beyond the horrific risk of severe accidents and the intrac­table problem of waste disposal, nuclear energy fails the two key tests for any climate solution: cost and time. More expensive than wind and solar, it is also far slower to bring online. A typical plant takes a decade to build; permitting and financing often add another. These are years we do not have.<BR><BR>Nuclear Is Not the Solution dismantles the myth of cheap, clean atomic energy and exposes the vested interests that seek to profit from the technology while offloading its costs and risks onto the public.
