Python Interfaces for Reactor Simulations

Project description


(P)ython (I)nterfaces for (R)eactor (S)imulations

The package provides Python interface to nuclear reactor simulation codes with the primary goal to organize data flow.

Cuurently implemented are MCNP and SCF interfaces; they can be used to organize coupled neutronics- and thermohydraulic calculations.

Documentation sources are in docs. An HTML version (possibly outdated) can be found in


PIRS evolved from a set of Python scripts helping to read/write MCNP-related files. It was mainly developed and applied for coupled MCNP-SCF simulations of square PWR assemblies and parts of the core. Documentation found in docs refers to large extent to that state of the code.

Occasionally, some modules were modified to meet other needs, without thorough checking of back compatibility and without reflecting the changes in documentation.


The package shall be refactored to fix the mentioned above incompatibilites. Some code (e.g. for reading meshtal files) was rewritten from scratch in another packages (see numjuggler, tovtk). Refactoring should take this into account and extract code with the same functionality into separate packages.
