Modern RECONR Module

The RECONR module is used to reconstruct resonance cross sections from resonance parameters and to reconstruct cross sections from ENDF nonlinear interpolations schemes. The output is written as a pointwise-ENDF (PENDF) file with all cross sections on a unionized energy grid suitable for linear interpolation to within a specified tolerance. Redundant reactions are reconstructed to be exactly equal to the sum of their reconstructed and linearized parts at all energies.

This is the documentation for the modern RECONR module 1. Please see the following pages for more information.


Much of this documentation was taken from the NJOY2016 manual and adapted as needed for the modern module in NJOY21.
