METHODOLOGY, VERIFICATION, AND PERFORMANCE OF THE CONTINUOUS-ENERGY NUCLEAR DATA SENSITIVITY CAPABILITY IN MCNP6

摘要

A continuous-energy sensitivity coefficient capability has been introduced into MCNP6. The methods for generating energy-resolved and energy-integrated sensitivity profiles are discussed. Results from the verification exercises that were performed are given, and these show that MCNP6 compares favorably with analytic solutions, direct density perturbations, and comparisons to TSUNAMI-3D and MONK. Run-time and memory requirements are assessed for typical applications, and these are shown to be reasonable with modern computing resources.
