The present volume reaffirms nuclear physics as an experimental science since the authors are primarily experimentalists and since the treatment of the topics might be said to be "experimental." (This is no reflection on the theoretical competence of any of the authors.) The subject of high-spin phenomena in heavy nuclei has grown much beyond the idea of "backbending" which gave such an impetus to its study five years ago. It is a rich, new field to which Lieder and Ryde have contributed greatly. The article "Valence and Doorway Mechanisms in Resonance Neutron Capture" is, in contradistinction, an article pertaining to one of the oldest branches of nuclear physics-and it brings back one of our previous authors. The Doppler-shift method, reviewed by Alexander and Forster, is one of the important new experimental techniques that emerged in the previous decade. This review is intended, deliberately, to describe thoroughly a classic technique whose elegance epitomizes much of the fascination which nuclear physics techniques have held for a generation of scientists. This volume concludes the work on the Advances in Nuclear Physics series of one of the editors (M. Baranger), whose judgment and style characterize that which is best in the first ten volumes. Many of our readers and most of our authors will be grateful for the high standards which marked his contributions and which often elicited extra labor from the many authors of the series.

This book addresses current activities in strong-motion networks around the globe, covering issues related to designing, maintaining and disseminating information from these arrays. The book is divided into three principal sections. The first section includes recent developments in regional and global ground-motion predictive models. It presents discussions on the similarities and differences of ground motion estimations from these models and their application to design spectra as well as other novel procedures for predicting engineering parameters in seismic regions with sparse data. The second section introduces topics about the particular methodologies being implemented in the recently established global and regional strong-motion databanks in Europe to maintain and disseminate the archived accelerometric data. The final section describes major strong-motion arrays around the world and their historical developments. The last three chapters of this section introduce projects carried out within the context of arrays deployed for seismic risk studies in metropolitan areas. Audience: This timely book will be of particular interest for researchers who use accelerometric data extensively to conduct studies in earthquake engineering and engineering seismology.

This book is intended as an introductory exposition of those nuclear energy systems concepts which are characterized by an integrated utiliz ation of complementary nuclear processes. Basic to such systems is the notion of synergism, which herein implies the cooperative interaction of selected nuclear reactions and system components so as to provide overall advantages not possible otherwise. While the concept of nuclear energy synergism has in recent years become the focus of an increasing number of conferences, scientific papers, and institutional in-house reports, no text which encompasses the major topics of the subject at a conceptual and analytical level has appeared. It is our aim to present a systematic characterization of these emerging nuclear energy concepts suitable for the senior university student of nuclear science and engineering as well for the active pro fessional involved in nuclear energy systems planning and analysis. In addressing the subject of nuclear energy synergism we have become most conscious of the tension between realism and vision in nuclear energy technology. As developed here, our perception of nuclear energy synergism is firmly rooted in the present and then seeks to proceed toward a heightened degree of compatibility and efficacy based on an enhanced integration of relevant nuclear processes. It is our view that such conceptual considerations must assume a greater role in the emerging techological orientation of nuclear energy systems planning.

The depth and breadth of the treatment is such that the book may be used as a text book for graduate and post-graduate courses, and will also be useful to those involved in decommissioning projects and radioactive waste management practices, such as project managers, engineers, health physicists and regulators. Although the general perception is that decommissioning is nothing more than dismantling and demolition of existing facilities, the book demonstrates that there are more to it and there are challenging technical issues to face. The book has been divided into three parts. Part One (Radiation Science) is the enabling part covering radiation, biological effects of radiation, radiological protection, and statistical methods. These subject matters are used and referred to throughout the rest of the book. Part Two incorporates the whole aspect of decommissioning covering decommissioning planning, regulatory aspects in decommissioning, project management, safety aspects, environmental impact assessment, decontamination and dismantling techniques etc.The last part includes radioactive waste management covering regulatory aspects, treatment and conditioning, storage and transportation, waste disposal etc.

The Erice International School of Fusion Reactor Techno logy held its 1981 course on - Unconventional Approaches to Fusion - in combination with the IAEA Technical Committee meeting on - Critical Analysis of Alternative Fusion Concepts -. The two events took place in the second half of March with an overlap of a few days only. The present proceedings include the first week's papers; those presented during the second week will be summarised in Nuclear Fusion. Right from the beginning of the course, and in particular In R. Carruthers' opening talk, it was clear that an uncon ventional approach was considered stimulating insofar as its con ception presented advantageous aspects with respect to the To kamak. Indeed the Tokamak was recognized as an - imper fect frame of reference- (K. H. Schmitter) in the sense that, al though it deserves to be considered as a frame of reference for the other devices because it is the most advanced in the scientific demonstration of controlled thermonuclear fusion, as a fusion reactor, however, the Tokamak does not seem to be completely satisfactory either from an economic or from an operational point of view, if compared with that - enticing ogre -, the proven fission reactor (less enticing to the public). Comparison of a Tokamak reactor with a PWR can be founded on considerations of such a basic nature that it becomes almost automatic to ask how far the various unconventional ap proaches to fusion are exempt from the Tokamak's drawbacks."

In recent years the effort devoted to assuring both the safety and reliability of commercial nuclear fission power reactors has markedly increased. The incentives for performing this work are large since the resulting im provement in plant productivity translates into lower fuel costs and, more importantly, reduced reliance on imported oil. Reliability and availability of nuclear power plants, whether fission or fusion, demand that more attention be focused on the behavior of materials. Recent experiences with fission power indicate that the basic properties of materials, which categorize their reliable behavior under specified conditions, need reinforcement to assure trouble-free operation for the expected service life. The pursuit of additional information con tinues to demand a better understanding of some of the observed anom alous behavior, and of the margin of resistance of materials to unpre dictable service conditions. It is also apparent that, next to plasma heating and confinement, materials selection represents the most serious chal lenge to the introduction of fusion power. The recognition of the importance of materials performance to nu clear plant performance has sustained a multimillion dollar worldwide research and development effort that has yielded significant results, both in quantification of the performance limits of materials in current use and the development and qualification of new materials. Most of this infor mation appears in the open literature in the form of research reports, journal articles, and conference proceedings."

The Editors take pleasure in presenting a further vol ume in their Annual Review Series. The present volume con tains six papers that may be said to span from the theory of design to the practice of operation of modern nuclear power stations, therefore concentrating on nuclear energy as a source of electrical power. Starting with the most mathem atical, and proceeding in the direction of technology, we have the Chudley and Brough account of a new interpretation of (linear) Boltzmann transport theory in terms of the characteristic or ray approach. This seems to be new in application here, but of course the method is the child of many classical studies in the solution of partial differen tial equations and proves to remarkably well-suited to modern computers and their numerical bases. We might put the article by Dickson and Doncals on the design of heterogeneous cores next, with its significance for fast reactors of the future. The various "central worth" discrepancies, with their implication for safety and relia bility founded on, inter alia, the Doppler effect, have made this a major area for resolution: to see that we can develop design methods and codes that will reconcile theory and exper, . . . iment to the point at which theoretical designs could be accepted for building without the need for a full-scale mock up, as had to be done in the 1950's for the light water re actors."

The use of tritium as a basic fuel material in a thermonuclear fusion reactor raises particular safety issues due to the combined effects of its physicochemical properties and its radioactive nature. Furthermore, the possibility of attaining further significant progress in developing and demonstrating the feasibility of tritium burning devices relies on the handling of tritium macroquantities, say tens of grams, in a safe and reliable manner. It is also certain that, apart from technological constraints, any validation and exploitation of thermonuclear fusion as a source of energy will be strongly conditioned by the application of stringent operational and environmental safety criteria derived from the norms of modern legislation and public acceptance considerations. This publication illustrates the most prominent safety aspects associated with the safe operation, maintenance and experimental utilization of a tritium handling facility. Besides the need for safe and reliable systems for tritium containment, monitoring and storage, particular attention is devoted to problems linked with tritium--material interaction and tritium processing, according to the different options applicable both to the tritium handling laboratory and future fusion devices. Selected topics, such as biological hazard, dosimetry, radiological protection and environmental safety are reviewed with particular attention to implications for operators and general public. Finally, outstanding experience gained during the recent JET operation and after many years of dismantling tritiated facilities at CEN--Valduc are illustrated. The book is principally addressed to scientists concerned with tritium R&D activities, as well as to designers and operators of tritium handling plants.

Such hazards occur during operation and maintenance, in normal or accidental conditions, and during decommissioning at the end of the life time of installations. The year 1989 has represented, for Teleoperation, an important landmark with the closure of the first commercial nuclear power stations which have reached the end of their life time.

Developed from the Global Foundation's International Conference on Environment and Nuclear Energy, held in October 1997, this volume examines the impact of nuclear energy on regional and global environmental issues under a variety of scenarios. These include competition in deregulated energy environments, constraints levied upon use of fossil energy, and possible expansion of nuclear power into energy sectors beyond the generation of electricity, process heat, and fuels production. It also assesses the overall role of nuclear energy in meeting future energy needs arising from growing world populations and economic development.

th This workshop was the 15 in a series that addresses the subject of the dynamics of nuclear reactions. These workshops are dedicated to the concept that bringing together scientists from diverse areas of nuclear reactions promotes the vibrant exchange of ideas. This workshop hosted presentations from experimentalists and theorists, intermediate energy to ultrarelativistic energies, and final results to recent speculations. Many of these scientists would not normally be exposed to the work done in other subfields. Thus the Winter Workshop on Nuclear Dynamics plays a unique role in information exchange and the stimulation of new ides. The field of nuclear dynamics has a bright future. New accelerators are being planned and completed around the world. New detectors are being constructed. New models and theories are being developed to describe these phenomena. The Winter Workshop on Nuclear Dynamics will continue to promote this lively and compelling field of research. WOLFGANG BAUER AND GARY D. WESTFALL v Previous Workshops The following table contains a list of the dates and locations of the previous Winter Workshops on Nuclear Dynamics as well as the members of the organizing committees. The chairpersons of the conferences are underlined.

The Tenth International Workshop on "Laser Interaction and Related Plasma Phenomena" was held November 11-15, 1991, at the Naval Postgraduate School, Monterey, California. This conference joined physicists from 11 countries (Australia, Canada, China, France, Israel, Italy, Spain, Switzerland, united Kingdom, USA, and the USSR). This meeting was marked by the inauguration of the EDWARD TELLER MEDAL FOR ACHIEVEMENTS IN FUSION ENERGY. This medal served as a celebration of the tenth conference in the 22-year series and as an opportunity to honor one of the world's greatest physicists and a leading pioneer in this field: Edward Teller. Four medals were awarded in the inaugural ceremony. The first recipient of the medal was Nobel Laureate Nikolai G. Basov, who served for many years as Director of the LebedevPhysical Institute of the Academy of Sciences of the USSR. In his address to Edward Teller, Dr. Basov underlined that Dr. Teller was the first in history to produce an exothermal nuclear fusion reaction, the mechanism that may now lead to an inexhaustive, environmentally clean, and low cost energy source in the future. This goal, he stressed, becomes more crucial as the greenhouse effect may not permit burning of fossil fuels for much longer. Basov also reviewed events leading the International Quantum Electronics Conferences of 1963 where he disclosed the first publication on laser fusion and that of 1968 where he reported the first observation of fusion neutrons using a laser-irradiated target. The second recipient was John H.

A survey of recent developments in the field of plutonium disposal by the application of advanced nuclear systems, both critical and subcritical. Current national R&D plans are summarized. The actinide-fuelled critical reactors are associated with control problems, since they tend to have a small delayed neutron fraction coupled with a small Doppler effect and a positive void coefficient. Current thinking is turning to accelerator-driven subcritical systems for the transmutation of actinides. The book's conclusion is that the various systems proposed are technically feasible, even though not yet technically mature. The book presents a unique summary and evaluation of all relevant possibilities for burning surplus plutonium, presented by experts from a variety of different disciplines and interests, including the defence establishment. The obvious issue - the non-proliferation of nuclear weapons - is vital, but the matter represents a complex technological challenge that also requires an assessment in economic terms.

Chemical pretreatment of nuclear wastes refers to the sequence of separations processes used to partition such wastes into a small volume of high-level waste for deep geologic disposal and a larger volume of low-level waste for disposal in a near-surface facility. Pretreatment of nuclear wastes now stored at several U. S. Department of Energy sites ranges from simple solid-liquid separations to more complex chemical steps, such as dissolution of sludges and removal of selected radionuclides, e. g. , 90Sr, 99Tc, 137CS, and TRU (transuranium) elements. The driving force for development of chemical pretreatment processes for nuclear wastes is the economic advantage of waste minimization as reflected in lower costs for near-surface disposal compared to the high cost of disposing of wastes in a deep geologic repository. This latter theme is expertly and authoritatively discussed in the introductory paper by J. and L. Bell. Seven papers in this volume describe several separations processes developed or being developed to pretreat the large volume of nuclear wastes stored at the US DOE Hanford and Savannah River sites. These papers include descriptions of the type and amount of important nuclear wastes stored at the Hanford and Savannah River sites as well as presently envisioned strategies for their treatment and final disposal. A paper by Strachan et al. discusses chemical and radiolytic mechanisms for the formation and release of potentially explosive hydrogen gas in Tank 241-SY-101 at the Hanford site.

This book of proceedings collects the papers presented at the workshop on "Diagnostics for Experimental Fusion Reactors" held at Villa Monastero, Varenna (Italy) September 4-12, 1997. This workshop was the seventh organized by the International School of Plasma Physics "Piero Caldirola" on the topic of plasma diagnostics and the second devoted to the diagnostic studies for the International Thermonuclear Experimental Reactor (ITER). The proceedings of the first workshop on ITER diagnostics were published by Plenum Press in 1996 with the title "Diagnostics for Experimental Thermonuclear Fusion Reactors". While many of the ideas and studies reported in the first workshop remain valid, there has been sub stantial progress in the design and specification of many diagnostics for ITER. This moti vated a second workshop on this topic and the publication of a new book of proceedings. ITER is a joint venture between Europe, Japan, Russia and USA in the field of con trolled thermonuclear fusion research. The present aim of ITER is to design an experimental fusion reactor that can demonstrate ignition and sustained burn in a magnetically confined plasma. To achieve this goal, a wide range of plasma parameters will have to be measured reliably. It is also anticipated that diagnostics will be used much more extensively as input to control systems on ITER than on present fusion devices and this will require increased relia bility and long-term stability.

Californium-252 is a neutron emitter with a high specific activity, making it useful in a variety of applications, the most spectacular of which is in brachytherapy for cancer patients. Radiation oncology has exhausted nearly every option for treating radioresistant tumors by photon brachytherapy, and therefore new types of radiation need to be studied to improve the curability of cancer. Audience: Californium brachytherapy is used in only a few radiation therapy centers in the world, so the book will be highly instructive for radiation oncologists, medical physicists and radiobiologists. The nuclear techniques used in clinical applications may also interest nuclear physicists and engineers.

A IUTAM symposium on 'Waves in Liquid/Gas and Liquid/Vapor Two-Phase Systems' was held in Kyoto, Japan, 9-13 May 1994. Sixty-three scientists partici pated coming from ten countries, and forty-two lectures were presented. The list of participants and the program are included in this volume. The symposium was held in response to the request of the participants in the IUTAM symposium 'Adiabatic Waves in Liquid-Vapor System' held at Gottingen in 1989. At that time, the need for another symposium in about five years had been indicated by all the participants. This symposium intends to develop the subject of wave properties in more general liquid-gas two-phase systems. Topics in this symposium may be classified as (1) waves in liquid-gas bubble systems including interfacial effects, (2) waves in gas( vapor )-droplets systems, (3) waves in films or stratified systems, (4) waves with liquid-vapor transition, (5) waves with vapor-liquid transition, (6) wave propagation near the critical point and (7) waves with low pressure effect. As for topic (1), experiments, numerical simulations and analytical approaches to waves in bubly liquids were discussed. The importance of interbubble interactions through the liquid-field is now well established at least in terms of potential theory. There was also a progress concerning the well-posedness of governing equations for void waves. For pressure waves there were some new phenomena, such as bubble cluster formation and the occurrence of three-dimensional structures, in addition to a progress from more qualitative studies to quantitative ones."

With the end of the Cold War, new opportunities for interaction have opened up between the United States and the countries of the Former Soviet Union. Many of these important initiatives involve the US Department of Energy (DOE) and the Ministry of the Russian Federation for Atomic Energy (MINA TOM). Currently, collaboration is under way which involves reactor safety, the disposition of fissile materials from the weapons program, radioactive waste disposal, and the safety of nuclear warheads. Another fruitful area of interchange resulted from the radiochemical storage tank accident at the site of the Siberian Chemical Compound at Tomsk-7 in 1993. DOE and MINATOM agreed to meet and exchange information about the accident for the purposes of improving safety. A meeting on the Tomsk tank accident was held in Hanford, Washington in 1993, followed by a second meeting in st. Petersburg, Russia in 1994 in which the agenda expanded to include radiochemical processing safety. A third exchange took place in 1995 in Los Alamos, New Mexico, and additional papers were presented on nonreactor nuclear safety. Following a planning session in 1996 in Seattle, Washington, it was decided to hold a fourth technical exchange on the broader subject of nuclear materials safety management. Through a grant from the North Atlantic Treaty Organization (NATO) Disarmament Programme, the meeting took place on March 17- 21, 1997, in Amarillo, Texas as a NATO Advanced Research Workshop (ARW) through grant no. DISRM 961315.

The surplus of plutonium in the world is both an important security issue, and a fact with implications for nuclear energy and environmental policy internationally. The two perspectives are inextricably intertwined in considering options for dealing with the plutonium surplus. It was for this reason that two research programmes at the Royal Institute of International Affairs - respectively on Energy and Environment, and on International Security - jointly approached NATO with a view to organising a work shop on the issue. It was most welcome then to learn that the NATO Science Programe was already supporting plans for a workshop on the issue, initiated by Richard Garwin, and we were pleased to accept the resulting invitation to host that workshop. DrGarwin prepared the initial agenda and established contacts and initial approaches to many of the participants; we were able to develop the agenda further and extend participation in some complementary ways. The result was a most lively and broad-ranging internation al and inter-disciplinary discussion. As the hosts, the RIIA was also given lead responsibility for producing the pro ceedings of the workshop as a publication for NATO. Many of the papers to the work shop are more technical than usually involved in a workshop at the Royal Institute. Yet this is an area in which the policy options are unusually dependent upon a good under standing of the technical issues. which themselves are often a matter of dispute."

Modern nuclear physics is a well developed branch of physical science, with wide-ranging applications of its results in engineering and industry. At the same time, the development of a consistent theory of nuclei and nuclear processes presents certain problems. It is well known that the most important aim of nuclear physics is the study of nuclear structure and the explanation of properties on the basis of the interaction between nucleons which constitute nuclei. Difficulties of a modern theory of the nucleus are caused by both an insufficient knowledge of nuclear interactions and the multi particle character of nuclear systems. Experimental data on nuclear interactions do not contradict the hypothesis of the pair character of nuclear forces. However, the absence of rigorous meth ods of calculations of many particle nuclear systems with strong interaction makes it necessary to use macroscopic nuclear models to describe particular nuclear properties. Nuclear models have been developed in different ways, and the models themselves have been modified and complicated. In spite of the visible discrepancy, different models of the nucleus significantly supple ment one another. The development of nuclear models has led to considerable progress in the understanding of atomic nuclei. The current results of theo retical nuclear physics are reported in numerous scientific papers. The most important and relevant experimental and theoretical results can be found in many monographs, the best of which are written by well-known experts in the field."

The first part of the conference explores two major environmental concerns that arise from fuel use: (1) the prospect that the globe will become warmer as a result of emissions of carbon dioxide, and (2) the effect upon health of the fine particles emitted as combustion products. The conference focused on the fact that there was lack of data direct enough to enable us to predict an entirely satisfactory result, and that makes policy options particularly difficult. With regard to (1) above, in the second half of the 20th century there were major increases in anthropogenic C02 emissions, and it is generally agreed that these were responsible for an increase in C02 concentrations. But the relationship between global temperature and CO2 concentrations remains murky. The principal problem is that water vapor is a more important greenhouse gas than C02 and that the concentrations of water vapor vary widely in time and space. The approach to this problem is probably, but not certainly, a positive feedback effect: as temperature increases so does the water vapor leading to further temperature increases. Scientists associated with the Intergovernmental Panel on Climate Change (IPCC) tend to believe the general features of the models. Other scientists are often less convinced.

This conference proceedings explores issues surrounding the replacement of existing nuclear power plants when they reach the end of their useful life. Topics covered include: Nuclear competitiveness regarding politics and power plant evolution; social acceptance regarding communication, information, waste, and safety proliferation; and durability regarding resources and effects on the environment.

This volume contains the proceedings of an International Conference on "Spin and Isospin in Nuclear Interactions," which was held in Telluride, Colorado USA, 11-15 March 1991. This was the fifth in a series of conferences held in Telluride every three years since 1979. In attendance at the conference were just under 100 participants, representing a total of 43 institutes from 12 different countries. In keeping with previous Telluride conferences, the role of spin and isospin degrees of freedom in both nuclear structure and nuclear interactions remained an important theme. Topics covered included new results on the spin- and isospin-dependent terms in the free and effective nucleon-nucleon interaction, Gamow-Teller excitations, charge and spin exchange with hadronic probes, and spin measurements with leptonic probes. Recent progress in the development of polarized sources, polarized targets, and po larimetry was also discussed, as were applications to neutrino physics and astrophysics. Whereas earlier Telluride conferences had dealt primarily with nucleon-nucleus inter actions, this meeting included extensive discussions on the role of spin and flavor in particle interactions, and on ways of "bridging the gap" between concepts usually as sociated with particle physics and the domain of more conventional nuclear physics. The conference consisted of morning and evening scientific sessions, leaving the afternoons free for informal discussions, recreation, and enjoyment of the scenic beauty of the Telluride area. In addition to the invited talks, time was allotted for contributed talks on new results."
