We report the development of a program, called KtoMTran, that converts KENO input files to MCNP input files. The code is based on parser and lexical analyzers Bison and Flex for translation. It has been tested with the sample cases that are provided with the KENO code as part of the SCALE package by RSICC. The input file conversion program still lacks capability to identify and translate certain special features in KENO input files. However, twenty-six out of the thirty-two input files for KENO sample problems are converted correctly and do not need any manual "fixing" before they can be run with MCNP. Five cases required minor modifications due to special boundary conditions. Since the translator program is not yet capable of handling criticality problems with a hole at the center of the geometry, it is not able to translate one such case in the KENO package. We also report a comparison of results of some selected problems obtained using KENO and MCNP.
