This Safety Guide, prepared jointly by the International Atomic Energy Agency (IAEA) and the International Labour Organization (ILO), provides guidance on fulfilling the requirements of the International Basic Safety Standards (IAEA Safety Standards Series No. GSR Part 3) with respect to occupational exposure. It provides general guidance on the development of occupational radiation protection programmes as appropriate for the sources of radiation likely to be encountered in the workplaces in question to fulfil the management's responsibility for protection and safety. Detailed guidance is also provided on the monitoring and assessment of workers' exposure due to external radiation sources and from intakes of radionuclides. The Safety Guide reflects the current internationally accepted principles and recommended good practices in occupational radiation protection, with account taken of the conceptual changes and technological enhancements that have occurred over the past decade.

The identification and assessment of threats provides an essential basis for the selection, design, and implementation of nuclear security measures. For nuclear material and other radioactive material that is under regulatory control, and associated facilities and activities, the results of this identification and assessment are expressed as a design basis threat or representative threat statement describing the intentions and capabilities of potential adversaries against which the materials and associated facilities and activities are to be protected. An Implementing Guide was issued in 2009 under the title of Development, Use and Maintenance of the Design Basis Threat which was updated and revised. The result of this revision is the current publication. It provides a stepbystep methodology for conducting a national nuclear security threat assessment including both physical and computer security aspects, and for the development, use and maintenance of design basis threats and representative threat statements.

Since the 1970s, the IAEA has been involved in the analysis of fuel failures in water cooled reactors in normal (nonaccident) operational conditions. This updated version of IAEA Nuclear Energy Series No. NFT2.1 provides information on all aspects of fuel failures in current nuclear power plant operations. It summarizes fuel failure occurrences and their mechanisms and root causes, as well as fuel failure prevention and management in plant operation for 97% of light and heavy water cooled nuclear power units operated worldwide during the period 2006-2015. Data on fuel failures from 1987 to 2006 extracted from three previous IAEA fuel failure reports are included and analysed in the present publication, together with the 2006-2015 fuel failure data, to reveal long term tendencies in fuel performance. In addition to fuel rod leakers, fuel structural damages and other fuel assembly issues are considered in the report.

Nuclear astrophysics is, in essence, a science that attempts to understand and explain the physical universe beyond the Earth by studying its smallest particles. "Cauldrons in the Cosmos," by Claus E. Rolfs and William S. Rodney, serves as a basic introduction to these endeavors. From the major discoveries in the field to a discussion of the makeup of stars to an explanation of standard lab techniques, this text provides students and scientists alike a thorough and fascinating survey of the accomplishments, goals, and methods of nuclear astrophysics. A classic in its field, "Cauldrons in the Cosmos" will surely remain an important reference in nuclear astrophysics for years to come.

""Written in an informal style that those uninitiated into the jargon of nuclear astrophysics and astronomy will find readable and illuminating. . . . A useful and long-awaited introduction to nuclear astrophysics."--G. J. Mathews, "Science

The Working Group "0ffshore Nuclear Power Plants" was established by the Commission of the European Communities in 1971. At that time it appeared that the option offered by creating new sites offshore should be explored. The present development of nuclear power has not, however, reached the stage where offs hore siting can be considered as a near or medium term proposition. The purpose of this report is to summarize the state of the art for the provision of floating or fixed structures, or man-made islands of the size needed for the construction of nuclear and other power stations. It describes the main factors which must be taken into account in the design and location of such islands and provides an indication of feasibility and cost for each design at the present time. It deals mainly with the civil engineering problems and not other major factors, such as the law of the sea, the rights of countries to locate nuclear establishments off their coast, their safety, security, the energy connection with the mainland, the marine ecology, the logistics, etc. ; many of these problems are directly related to the site and have major economic and political implications. By studying application examples the Working Group has occupied itself with these other factors.

The study which fonns the second volume of this series deals with the interplay of groups and composite particle theory in nuclei. Three main branches of ideas are de- veloped and linked with composite particle theory: the pennutational structure of the nuclear fermion system, the classification scheme based on the orbital partition and the associated supennuitiplets, and the representation in state space of geometric trans- fonnations in classical phase space. One of the authors (p. K.) had the opportunity to present some of the ideas under- lying this work at the 15th Solvay Conference on Symmetry Properties of Nuclei in 1970. Since this time, the authors continued their joint effort to decipher the conceptual struc- ture of composite particle theory in tenns of groups and their representations. The pattern of connections is fully developed in the present study. The applications are carried to the points where the impact of group theory may be recognized. The range of applications in our opinion goes far beyond these points.

Resonances are a common feature of many systems in nature. They reveal much about the structure of such systems. This book provides a comprehensive and up-to-date account of a similar phenomenon in atomic nuclei, the giant resonances. It describes experimental facts, how these are obtained, and how they fit into existing theoretical models. It also includes a short history and an overview of the main achievements in this field.

The present European success in neutron physics and in neutron scattering applied to condensed matter research rests upon the subtle interaction of new instrument requirements for an expanding scientific program in Physics, Chemistry and Biology and the programme of invention of neutron instruments, which has long been a characteristic of neutron physics, particularly in Germany. Although this distinction between the role played by the instrument demands of "problem oriented" scientists and the interest of "instrument inventors" is somewhat facile, I believe it to be worthwhile since progress needs both components; many of the uses of a new method only becoming evident as it is improved under the conditions of real experiment. The Institut Laue Langevin in Grenoble brings both streams together and a measure of its importance on the or1d scene can be seen in Figure 1, which charts the world publications in Neutron Physics and Neutron Scattering since the neutron's discovery. This figure also clearly shows the correlation between innovation (and publication) in neutron science and the flux of neutrons available. hi1st in 1936 it was possible to demonstrate the wave properties and diffraction of neutrons(1)(2) it was not until 1944 with the "pile" CP3 at Argonne National Laboratory that intensities were high enough to stimulate the construction of the first neutron diffractometer and development 22 c 900 A_ UJ DIDO, SACLAY, GARCHING LL en WORLD TOTAL::: i 700 m ORRR, NRU, NlO:: B_ LL.

A Conference is one thing, its Proceedings is another issue. The 1976 Neutrino Conference at Aachen met with friendly approval, within and beyond the brotherhood of neutrino physicists. The generally well informed "Frankfurter Allgemeine Zeitung" spoke of a "Sternstunde" of Science . . . And even without invoking the stars, we may register with some satisfaction that several important developments came to an end. "Charm is found " - hailed Alvaro de Rujula the most spectacular event of the Conference. The organizers held this opinion even before, as is evidenced by the Conference badge: a little aluminum tetra hedron, symbolizing the four quarks, and fastened by a three-coloured string. In fact, the history of the discovery of charm goes a long way back, perhaps even back to the first CERN neutrino experiment in 1963/64, when indications of charged lepton pairs were recognized - long before charm was taken serious. Muon pairs were established by the Harvard-Pennsylvania-Wisconsin Group in 1974, and correctly inter preted in terms of charm. At the Paris Neutrino Meeting in 1975 the BNL event came, confirming the con nection with strangeness and suggesting charm production to occur at quite low energies."

This Safety Guide provides recommendations and guidance on achieving and demonstrating compliance with IAEA Safety Standards Series No. SSR-6 (Rev. 1), Regulations for the Safe Transport of Radioactive Material (2018 Edition), which establishes the requirements to be applied to the national and international transport of radioactive material. Transport is deemed to comprise all operations and conditions associated with and involved in the movement of radioactive material, including the design, fabrication and maintenance of packaging, and the preparation, consigning, handling, carriage, storage in transit, shipment after storage and receipt at the final destination of packages. The Advisory Material is not a stand-alone text. It is to be used concurrently as a companion to the IAEA Safety Standards Series No. SSR-6 (Rev. 1) and each paragraph of this guide is numbered correspondingly to the paragraph of the Regulations to which it most directly relates.
