... The NRC Regulatory Guide 1.99 (R.G. 1.99) Revision 2 was based on 177 surveillance data points and the EPRI data base, where 76% of 177 data points and 60% of EPRI data base were from Westinghouse's data. Therefore, other vendors' radiation environment may not be properly characterized by R.G...

... Investigations of regulatory issues, such as vessel integrity over plant life, vessel failure, and plant license renewal, can be greatly expedited by the use of a well-designed computerized data base. Also, such a data base is essential for the validation of embrittlement prediction models...

.... However, because of differences in procedures and equipment, many of the data bases were incompatible. In 1964, as a step toward establishing more uniformity, the Bureau of the Budget (now the Office of Management and Budget, OMB) issued “Circular A-67” which presented guidelines for collecting water data...

... In the catalog, sorption isotherms are plotted for more than 100 materials. Measured sorption values from different sources are put into a data base, and for each set of values the best curve through desorption and adsorption measuring points are fitted using the extended Posnow equation. A page...

... The architecture of the Embrittlement Data Base (EDB) is described. This database contains a comprehensive collection of experimental data related to irradiations of reactor pressure vessel steels in surveillance capsules and test reactors. Software is being developed for easy retrieval...

... ASTM Committee E-49 on the Computerization of Materials Property Data was instituted in 1986 to provide guidance to individuals and organizations building machine-readable data bases and to aid in the development of compatible and consistent sources capable of a reasonable exchange...

... Recent trends in the development of materials data systems in Japan are reviewed. As the building of materials data bases is a major concern of industry, academic societies, and government laboratories and the sharing of materials information is a common need among interested parties...

... An integrated data base is the heart of an integrated manufacturing system. It serves as the glue to bind together heterogeneous component systems, which are often developed independently for supporting product design, process planning, manufacturing, product inspection and testing, and product...

... While the computer technology, both hardware and software, exists to allow easy and comprehensive access to computerized data on engineering materials, only a few data bases are publicly available today. The reason for this is a set of barriers based on socioeconomic factors that are only partly...

... Managing the data in a composite materials data base, such as the data base required for MIL-HDBK-17, is a complex task. MIL-HDBK-17, “Polymer Matrix Composites,” is a fully coordinated military document currently supported by the Army, the Air Force, and the Federal Aviation Administration...

... has been transferred from the Data Center's graphics workstations to a PC. Demonstration software has been developed for retrieving and plotting the phase diagrams on the PC's monitor from the PC-based Phase Diagram Data Base. In addition, the software allows the operator to retrieve data from...
