UWB1

Fast nuclear fuel depletion code

Overview

UWB1 is a fast nuclear fuel depletion code developed by Czech universities (University of West Bohemia in Pilsen and Czech Technical University in Prague). Although the code is intended for fuel design optimization with burnable absorbers, it can be used to calculate fuel depletion calculations in general.


Features

The code's main features include:

burnup solver utilizing CRAM method

parallelized Monte Carlo transport solver

2sPC depletion scheme

data libraries based on ENDF/B-VII.1 nuclear data

Currently, arbitrary 2-D geometry described by concentric cylinders in square or triangular lattice is supported. The code is able to calculate fuel inventory and multiplication factor during depletion.
