Monte Carlo methodologies for neutron streaming in diffusion calculations - Application to directional diffusion coefficients and leakage models in XS generation
… calculations at core level. In this thesis, the Serpent 2 Monte Carlo reactor physics burnup calculation code is used in order to test a set of diffusion coefficient models, as well as neutron leakage methodologies at assembly level. The tests include novel anisotropic diffusion coefficient and …

Neutronics and thermal-hydraulics analysis of transatomic power molten salt reactor (TAP MSR) core under load following operations
… operations using a Monte Carlo code, Serpent 2, as well as a UIUC-developed MOOSE-based code, Moltres. A simulation method was developed to determine the operational bounds of the TAP MSR core and its transient behavior under rapid power ramps using both fresh fuel salt and fuel salt …

Advancement and verification of Moltres for molten salt reactor safety analysis
… Monte Carlo neutron transport results from Serpent 2. The multiplication factors k_eff, delayed neutron fractions beta, temperature reactivity coefficient alpha_T, and the six-group neutron energy spectra from Moltres agreed with the high fidelity simulation results from Serpent 2. The k_eff …

Advanced online fuel reprocessing simulation for thorium-fueled molten salt breeder reactor
… SaltProc couples with the Monte Carlo code, SERPENT 2, for neutron transport and depletion calculations. SaltProc capabilities include a generic geometry capable of modeling multi-region and multi-flow systems, time-dependent feeds and removals, and specific separation efficiency for each …

Impact of nuclear data libraries for criticality calculation of HTGR
… Test Reactor (HTTR) and HTR-10 reactor models. Serpent 2 was used to calculate criticality and its uncertainty due to nuclear data, using data from evaluated nuclear data libraries ENDF/B-VIII.1 and JENDL-5. Uncertainty quantification demonstrates that for both HTTR and HTR-10, keff uncertainty …
