RSICC DATA PACKAGE DLC-198

1. NAME AND TITLE OF DATA LIBRARY

TR-EDB: Test Reactor Embrittlement Data Base, Version 1.

2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS

The data can be accessed by the provided menu-driven software or by any program that can access dBASE files.

3. CONTRIBUTOR

Oak Ridge National Laboratory, Oak Ridge, Tennessee, through the Energy Science and Technology Software Center, Oak Ridge, Tennessee.

4. HISTORICAL BACKGROUND AND INFORMATION

TR-EDB is a collection of results from irradiations in materials test reactors. It complements the Power Reactor Embrittlement Data Base (PR-EDB), whose data are restricted to the results from the analysis of surveillance capsules in commercial power reactors. The rationale behind this restriction was the assumption that the results of test reactor experiments may not be applicable to power reactors and could, therefore, be challenged if such data were included.

5. APPLICATION OF THE DATA

The current data collection of TR-EDB contains primarily Charpy test data, which are accompanied in most cases by tensile tests for the same irradiation conditions.

6. SOURCE AND SCOPE OF DATA

Information is available for 1230 different irradiated sets, 797 of which are from base material (plates and forgings), 378 from welds, and 55 from heat-affected-zone materials. The chemistries of the investigated materials span also a fairly wide range, particularly in the content of copper and nickel, which are considered the most important contributors to embrittlement sensitivity. Complete chemistry information is available for 1095 of the 1230 samples (after discarding the HAZ information).

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAM

Compiled executable menu-driven software facilitates maintenance, processing, plotting, and evaluations of the data. Running the EDB utilities requires an IBM-compatible PC, preferably with 80286 (AT) or 80386 processor, and a hard disk. At least 512 K RAM is recommended. A matching coprocessor 80287/80387 is also required. The graphics programs are written for an EGA or VGA screen with 640 x 350 pixel resolution. The user will also find that dBASE compatible software and a utility to dump the screen to a printer are useful.

This package was submitted initially released by ESTSC in June 1994 and was not modified when it was transferred to RSICC and released in February 2002. The database installs and executes without error. Only executables, data base files and dBASE support files are supplied.

8. DATA FORMAT AND COMPUTER

dBASE III PLUS format for the main data files, IBM-compatible MS-DOS systems. (D00198/IBMPC/00).

9. TYPICAL RUNNING TIME

Dependent on user input.
