Introduction

Hello,

Welcome to our GitHub repository. We are members of the reactors physics laboratory at the Federal University of Rio de Janeiro (UFRJ/COPPE) and this is our modifications in the nuclear data processing code called FRENDY, developed by the Japan Atomic Energy Agency (JAEA). Our primary goal is to generate deformed neutron cross-sections using the Kaniadakis statistics.

(This topic will be continually improved with the involved theory)

How to run

In order to TEST these modifications, it is mandatory to install the FRENDY code in your machine. The following website explains how to do that: https://rpg.jaea.go.jp/main/en/program_frendy/

These are the files that will be modified inside FRENDY in order to calculating deformed cross-sections using the Kaniadakis distribution

Utilized folders inside FRENDY:

  • frendy_XXXXXXXX\tests\ReconResonance (File "ResonanceXSCalculatorTest.cpp" and Folder "for_test" )

  • frendy_XXXXXXXX\frendy\ReconResonance (Files "ResonanceXSCalculator.cpp" and "ResonanceXSCalculator.hpp")

Folder to see the results files:

  • frendy_XXXXXXXX\tests\ReconResonance\comp_njoy

Folder to start the compilation (Windows, via 'wsl' command):

  • frendy_XXXXXXXX\tests\ReconResonance

The Fadeeva Package

In order to calculate some critical Faddeeva functions inside our analytical solution for the deformed Doppler broadening function, we implemented the Faddeeva Package, developed by the MIT. Consequently, the modifications will only work with the Faddeeva files in both aforementioned folders. We thank Professor Steven G. Johnson for his incredible work.
