Nuclear Reaction Data

Modern technologies based on nuclear processes, such as nuclear weapons, power reactors, radiation and materials detectors, medical imaging devices, and radiation therapies, often require more accurate and complete knowledge of nuclear reaction dynamics and nuclear structure. Group members measure, collect, and evaluate nuclear data and incorporate these data into libraries (databases), which are used in LLNL simulations.

The data are usually presented in one of three formats:

Support for ENDL can be found here. To view ENDL and ENDF data, visit the NADS graphical data plotter. More detail on the translated ENDF data can be found on the ENDF translation page.

Software tools to generate and manage the nuclear reaction databases are provided by the group. An example is FUDGE, which allows researchers to examine the sensitivities of the computed results to variations in the underlying nuclear reaction data. Other tools format the data to be used more efficiently in specific applications:

• NADS Nuclear and Atomic Data System - This project organizes and presents nuclear and atomic data as a web tool.
• FUDGE For Updating Data and Generating ENDL - Highly customizable Python program that reads and modifies ENDL data.
• FETE From ENDF/B-VI To ENDL - Translation project.
• Actinides - Comparison of evaluation actinide cross sections to EXFOR data
• ENDEP Tool to calculate ENergy DEPosits.
