OECD/NEA intercomparison of deterministic and monte carlo cross-section sensitivity codes using sneak-7 benchmarks
Abstract : A sensitivity benchmark exercise was organized within the scope of the Uncertainty Analysis
in Modeling (UAM) project of the OECD/Nuclear Energy Agency (NEA) to develop and
compare methods for the sensitivity and uncertainty computations of the effective
multiplication factor (keff) and the effective delayed neutron fraction (eff). Several solutions
were received using different codes, both deterministic (SUSD3D, SNATCH) and Monte
Carlo (TSUNAMI-3D, XSUSA, SERPENT2, MCNP6). In this paper the performances of
several codes and methods for the keff sensitivity and uncertainty computations are intercompared. The sensitivity and uncertainty codes were applied to the SNEAK-7A and -7B fast
neutron benchmark experiments from the IRPhE database. Good general agreement
between the sensitivities, both for integral values and sensitivity profiles, was observed.
