Quadriga-general and powerful lattice code calculation framework

Popis výsledku v původním jazyce

Lattice codes, used for calculation of macroscopic homogenized cross-sections, are - on the user side - indisputably the most difficult part of the reactor analysis computation stack. The geometry of fuel assembly must be described in great detail, variety of fuel assembly designs (enrichment, profiling) is infinite and the lattice code options and parameters are complex. This is a challenge for the analytical team: everyone in need of a library for new fuel designs should either be familiar with the lattice code or would be dependent on the lattice code expert. Moreover it is very challenging to have consistent versions of lattice code calculations: The analyst needs to be sure that the data libraries prepared five years ago by his colleague follow the same methodology and use the same models as those he is building right now. To solve the aforementioned issues we have developed QUADRIGA - a general and powerful lattice code calculation framework. The core element of QUADRIGA is a sophisticated templating system, based on a parameterized templates. The templates, using a domain specific language, are prepared by a lattice code expert and the end user, preparing libraries for the fuel variants does not need to know the lattice code itself to run any calculations needed. He uses a graphical user interface to build lattice code input files and also to run the calculations on a computer cluster - all these tasks are managed by the software. The current generation of the QUADRIGA framework features many exciting capabilities, including multiple lattice code support, uncertainty sampling and both triangular and square lattice geometry tools. The paper presents QUADRIGA features, interesting parts of it internals and usage scenarios.
