Book Description
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 Description
The events described in this report illustrate different malfunctions that have occurred at pressurized water reactors involving control rods or control rod drives. All malfunctions were detected during testing periods; none compromised safety of the plant. In one instance, deposits of epoxy-like material on the faces of the clutches in control rod drive mechanisms (CRDM's) caused failures of single control rods to drop on signal. In a second case, CRDM's were damaged when they were dropped with the hydraulic dashpots either empty or only partially filled because of inadequate venting through housing seals. Third, intermittent response to withdraw and insert signals on one control rod was traced to a dragging motor brake on the CRDM. Finally, loose dowel pins used to position the stationary brake discs were found to be the cause of mis-positioned control rods.

Book Description
The control rod drive mechanisms and associated instrumentation in the Shippingport PWR were in satisfactory operating condition. Deficiencies that were observed during the test and subsequently corrected were: no positive indication of movement in rods 11, 82, 62, 53, and 14, as shown on the rod position indicating lights; and the bottom indicator coil for rod 81 was connected improperly. After the deficiencies were corrected, the test was rerun for the rods in question and all operated satisfactorily. (auth).
