Book Description
This report explores the requirements for the design and analysis of concrete containment and shows how newer material technologies such as self-consolidating concrete (SCC) and fiber reinforcement could assist in the constructability and durability of new nuclear power plant facilities. SCC for example, enables concrete to flow in the forms around the reinforcement and provides a more uniform adhesion with the reinforcement. Additionally, fiber reinforcement in the concrete mix increases bonding capability, thus making the concrete less likely to fracture. In particular, the ease of constructability benefits offshore floating nuclear power plants and preapproved modular power plants. To differentiate, the offshore plant would employ the assembly line to make all the plants the same while the modular plant, designed to be used anywhere, is not site specific and is typically smaller. Regarding research method, the report starts with the history of the nuclear industry in the United States, including the last nuclear power plant constructed, clarifying that nuclear energy was first harnessed for a submarine propulsion system before being employed to generate electricity. After these early endeavors, two major accidents, Three Mile Island (March 28, 1979) and Chernobyl (April 26, 1986), provided information regarding the lack of safety of nuclear power plant design and operation. Since the containment building is the focus of this report, recognizing the loads and the load combinations for design was the next step in research. Following that, the next step was to determine the design considerations and analyze the containment structure. New material technologies clearly have opened the door to new construction techniques, and the combination of new materials and methods offers structural engineers opportunity to build inherently safer nuclear power plants.

Book Description
It was in 1978 that the former FIP (Fédération Internationale de la Précontrainte) published a state-of-art report on Containments for Nuclear Power Plants (NPPs). In 1996 the then FIP Commission 7 Concrete pressure vessels and containments discussed the necessity to up-date this document. After the merger of FIP with CEB (Comité Euro-International du Béton) into fib (fédération internationale du béton - international federation for structural concrete) had taken place in 1998, these activities were continued by a new fib Task-Group 1.3 Containment structures of fib Commission 1 Structures. The decision to update the 1978 report was kept with the intention to give a broad and well illustrated review of existing NPP containments as the most characteristic and complex building of nuclear power plants. Following the description of containments for different reactor systems the state-of-art report includes considerations on safety as the basic purpose of the containment, which underlies all design and construction aspects and necessitates a strict monitoring and inspection program during the whole life of the structure. Regulatory requirements and their evolution as well as recent developments, conceptual and technological, are presented. The report is complemented by two annexes on CD ROM giving some general information (on 160 NPPs built since 19972) and some more detailed data on six typical recent NPP containments. This work has been achieved during the years 1999 and 2000 thanks to the participation of members of fib Commission 1 and particularly of its Task Group 1.3, involving also further invited experts in the nuclear field from many countries all over the world.

Book Description
This book provides a general introduction to the topic of buildings for resistance to the effects of abnormal loadings. The structural design requirements for nuclear facilities are very unique. In no other structural system are extreme loads such as tornadoes, missile and loud interaction, earthquake effects typical in excess of any recorded historical data at a site, and postulated system accident at very low probability range explicitly, considered in design. It covers the whole spectrum of extreme load which has to be considered in the structural design of nuclear facilities and reactor buildings, the safety criteria, the structural design, the analysis of containment. Test case studies are given in a comprehensive treatment. Each major section contains a full explanation which allows the book to be used by students and practicing engineers, particularly those facing formidable task of having to design complicated building structures with unusual boundary conditions.

Book Description
The Structural Aging Program provides the US Nuclear Regulatory Commission with potential structural safety issues and acceptance criteria for use in continued service assessments of nuclear power plant safety-related concrete structures. The program was organized under four task areas: Program Management, Materials Property Data Base, Structural Component Assessment/Repair Technology, and Quantitative Methodology for Continued Service Determinations. Under these tasks, over 90 papers and reports were prepared addressing pertinent aspects associated with aging management of nuclear power plant reinforced concrete structures. Contained in this report is a summary of program results in the form of information related to longevity of nuclear power plant reinforced concrete structures, a Structural Materials Information Center presenting data and information on the time variation of concrete materials under the influence of environmental stressors and aging factors, in-service inspection and condition assessments techniques, repair materials and methods, evaluation of nuclear power plant reinforced concrete structures, and a reliability-based methodology for current and future condition assessments. Recommendations for future activities are also provided. 308 refs., 61 figs., 50 tabs.
