Monte Carlo method and its variance reduction techniques for on-stream coal slurry parameter determination

The special purpose Monte Carlo program McMesh was used to study neutron transport in coal slurries for on-stream determination of the slurry parameters. McMesh uses the mesh weight window method as the major variance reduction technique with other methods such as exponential transforms and correlated sampling included as options. There was good agreement between the calculated results from McMesh and from MCNP, a general Monte Carlo program, but McMesh was more efficient and more convenient.
