COMPONENT RELIABILITY DATA FOR USE IN PROBABILISTIC SAFETY ASSESSMENT

The IAEA Data Base was compiled using dBASEI commercial software; this software package is therefore needed to use the Data Base alone.
Using the dBASE software one can browse through records, list them, and retrieve information stored to the screen or print it in different ways. With dBASE III commands it is possible to select individual records or groups of records with given common characteristics (for example source, component type etc.).
The purpose of the Data Base for stand-alone use is to have readily available several data sources for each single component. The data base can also be used for assessing total ranges of data (extremes).
One of the peculiarities of the Data Base is that failure rates (as well as upper and lower bounds) are stored in the character format (instead of numerical), so direct calculation is not possible. The reason for it is that dBASE III software does not allow numbers to be presented in exponential format.
