AbstractNFCSim is an event-driven, time-dependent simulation code modeling the flow of materials through nuclear fuel cycle. NFCSim tracks mass at level discrete reactor charges/discharges and logs history material as it progresses a detailed series processes facilities, generating life-cycle balances for any number reactors. ideal tool analysis - economics, sustainability, or proliferation resistance nonequilibrium, interacting, evolving fleets. The software couples with criticality burnup engine, LACE (Los Alamos Criticality Engine). implements piecewise-linear, reactor-specific reactivity model its calculations. This constructs fluence-dependent traces facility; designed to address economies in which either steady state never obtained poor approximation. operates transient equilibrium management regimes refueling batch level, derives reactor- cycle-dependent initial compositions, invokes ORIGEN2.x carry out
