Book excerpt: Materials in a nuclear environment are exposed to extreme conditions of radiation, temperature and/or corrosion, and in many cases the combination of these makes the material behavior very different from conventional materials. This is evident for the four major technological challenges the nuclear technology domain is facing currently: (i) long-term operation of existing Generation II nuclear power plants, (ii) the design of the next generation reactors (Generation IV), (iii) the construction of the ITER fusion reactor in Cadarache (France), (iv) and the intermediate and final disposal of nuclear waste. In order to address these challenges, engineers and designers need to know the properties of a wide variety of materials under these conditions and to understand the underlying processes affecting changes in their behavior, in order to assess their performance and to determine the limits of operation. Comprehensive Nuclear Materials, Second Edition, Seven Volume Set provides broad ranging, validated summaries of all the major topics in the field of nuclear material research for fission as well as fusion reactor systems. Attention is given to the fundamental scientific aspects of nuclear materials: fuel and structural materials for fission reactors, waste materials, and materials for fusion reactors. The articles are written at a level that allows undergraduate students to understand the material, while providing active researchers with a ready reference resource of information. Most of the chapters from the first Edition have been revised and updated and a significant number of new topics are covered in completely new material. During the ten years between the two editions, the challenge for applications of nuclear materials has been significantly impacted by world events, public awareness, and technological innovation. Materials play a key role as enablers of new technologies, and we trust that this new edition of Comprehensive Nuclear Materials has captured the key recent developments. Critically reviews the major classes and functions of materials, supporting the selection, assessment, validation and engineering of materials in extreme nuclear environments Comprehensive resource for up-to-date and authoritative information which is not always available elsewhere, even in journals Provides an in-depth treatment of materials modeling and simulation, with a specific focus on nuclear issues Serves as an excellent entry point for students and researchers new to the field

Book excerpt: A high pressure rig designed to perform dynamic calibrations of pressure measuring systems was constructed and commissioning tests with various differential pressure measurement assemblies were conducted. although the test results are not general enough in nature to be used for the design of other pressure measuring systems, they have demonstrated the usefulness of the calibrating rig in testing fairly complex assemblies. in addition, these tests have provided experience which will prove valuable for future work in this area.

Abstract: Abstract of thesis entitled POSITRON ANNIHILATION SPECTROSCOPIC STUDIES OF UNDOPED N-TYPE ZINC OXIDE SINGLE CRYSTAL submitted by HUI CHUN WAI for the Degree of Master of Philosophy at The University of Hong Kong in August 2006 Positron lifetime spectroscopy and coincidence Doppler broadening spectroscopy (CDBS) were used to study the defects in two pieces of hydrothermal (HT) grown ZnO single crystal samples (HT1 and HT2) obtained from two different companies, namely University Wafer, US, and MaTecK, Germany. Single component model could offer good fitting to the lifetime spectra of HT1 and HT2 at temperatures ranging from 25K to 285K. The room temperature positron lifetimes of HT1 and HT2 were found to be 191ps and 181 ps, respectively. The observation was associated with saturated positron trapping into two different Zn-vacancy related defects existing in the two samples. For HT1, the lifetime was observed to be temperature independent. However for HT2, the lifetime had constant value with temperature higher than 200K. It then decreased with decreasing temperature and reached the value of 172ps at 30K. This temperature dependence of lifetime could be explained by the presence of an additional positron shallow trap. Positron-electron autocorrelation function (AF) was extracted from the CDBS spectra. The obtained AF mappings of HT1 and HT2 at room temperature confirmed that the defects existing in HT1 and HT2 should have different microstructures. Positron lifetime spectroscopy was also performed on undoped pressurized melted grown n-type ZnO single crystal. Two-component model was required to give good description to the lifetime spectra. The two lifetime components were found to have temperature independent values of 181ps and 366ps, which were attributed to saturated positron trapping into two defects, V related defect and vacancy cluster respectively.
