PREPRO 2012 Home Page

The ENDF/B Pre-processing codes (PREPRO), is a collection of 17 computer codes, which are designed to convert ENDF/B formatted neutron and/or photon data from the original distributed form to a form in which the data can be used in applications.

These codes also allow you to view the data, on-screen and/or hardcopy.

The ENDF/B Pre-Processing Codes run on virtually ANY Computer.

Here you can download the codes and documentation for ANY computer.

Here you can also download the BEST Input Parameters to use with each code.

Recent changes in ENDF/B-VII Format and procedures, as well as the evaluations themselves makes it impossible for versions of the ENDF/B pre-processing codes earlier than PREPRO 2012 (2012 Version) to accurately process current ENDF/B-VII evaluations.

The present codes can handle all existing ENDF/B-VII.0 and VII.1 evaluations.

Documentation is NOT included with downloaded codes for each computer. You must download documentation separately.
