The purpose of PR-EDB is to provide the technical bases for voluntary consensus standards, regulatory guides, standard review plans, and computer codes.
PR-EDB Version 3.0 upgrades the previous Version 2.0, which was released in January 1994. The first compilation of embrittlement data for power reactors was completed in 1989 and was subsequently submitted to the Electric Power Research Institute (EPRI) for additional verification and quality assurance by the reactor vendors.
The current version of the PR-EDB lists test results of 104 heat-affected-zone (HAZ) materials, 115 weld materials, and 141 base materials, including 103 plates, 35 forgings, and 3 correlation monitor materials that were irradiated in 321 capsules from 106 commercial power reactors. The data files are given in MS Access format and can be accessed with any personal computer using the Windows operating system. "User-friendly" utility programs have been written to investigate radiation embrittlement using this database. Utility programs allow the user to retrieve, select and manipulate specific data, display data to the screen or printer, and fit and plot Charpy impact data.
