MCNPy

A Python package for working with MCNP input and output files. MCNPy provides a lightweight alternative to mcnptools, offering essential functionality for parsing, analyzing, and manipulating MCNP files in Python.

Features

• Parse and manipulate MCNP input files (materials, PERT cards)
• Read and analyze MCTAL output files
• Compute sensitivity data
• Generate and visualize sensitivity profiles
• Create Sensitivity Data Files (SDF)

Installation

pip install mcnpy

Quick Start

import mcnpy

# Read an MCNP input file
inputfile = "path/to/input_file"
input_data = mcnpy.read_mcnp(inputfile)

# Read a MCTAL file
mctalfile = "path/to/mctal_file"
mctal = mcnpy.read_mctal(mctalfile)

# Access materials
materials = input_data.materials

# Compute sensitivity data
from mcnpy.sensitivities import compute_sensitivity
sens_data = compute_sensitivity(inputfile, mctalfile, tally=4, nuclide=26056, label='Sensitivity Fe-56')
