The Testing and Application of Continuous-Energy Neutron Cross Section Library HENDL-ADS/MC

A point-wise cross-section data library HENDL-ADS/MC (Hybrid Evaluated Nuclear Data Library) has been produced by FDS team to do the nuclear analysis for the ADS system. The HENDL-ADS/MC library contained 408 nuclide cross-section files including actinides, fission products and structural materials for neutron energy up to 150 MeV. The nuclear library also contained several sub-libraries with different temperatures. A series of neutron integral experiments and critical safety benchmarks have been performed to test the availability and reliability of the HENDL-ADS/MC data library. To validate and qualify the reliability of the high neutron energy cross section for HENDL-ADS/MC library further, a series of high neutron shielding experiments have been performed using MCNP. The testing results indicated the accuracy and reliability of HENDL-ADS/MC library.Copyright

Preliminary Fuel Cycle Analysis of a Fusion-Driven Subcritical Reactor

The levelized cost of electricity (LCOE) has been performed to compare two fuel cycle scenarios: a once-through cycle (LWR OT) and a fusion Cdriven reactor, namely FDS-SFB, recycling employing PUREX (Purex-SFB). In order to estimate the LCOEs, the mass flows based on an equilibrium mode were analysed. The sensitivity of the results to variations in key parameters was also performed. A simple dynamic model was also constructed to consider other important factors that characterize a fuel cycle, e.g. resource utilization, environmental effects.The results of economics are as flows: LWR OT 29mills/KWh, Purex-SFB 48.19mills/KWh. It was found that the capital cost accounts for the largest proportion of the LCOEs. The fuel cycle cost analysis indicates that the FDS-SFB fuel cycle cost will be competitive with the once-through fuel cycle. Also, sensitivity analysis indicates that fuel cycle cost of LWR would be higher than that of the LWR-SFB fuel cycle with the uranium Price rising. Dynamic model analysis indicates that Purex-SFB could reduce the amounts of MA and the amounts of natural uranium considerably compared with LWR OT.Copyright
