Monte Carlo Approaches for Uncertainty Quantification of Criticality for System Dimensions
X-Computational Physics Division, Los Alamos National Laboratory, P.O. Box 1663, Los Alamos, NM 87545
MCNP6 is used to estimate uncertainties from geometric tolerances using forward and adjoint methods. Results are obtained and the forward and adjoint approaches appear to agree in some cases where the responses are not non-linearly correlated. In other cases, the uncertainties in k disagree for reasons not yet known.
Key words: MCNP / adjoint / perturbation / sensitivity
