摘要：The demand of natural uranium of two different cycle options of China's PWRs were calculated in this paper, the once-through cycle route (OTC) is 197.2 t/8.702 TWh and the partial recycling in PWR route (PRR) is 131.0 t/8.702 TWh. The fuel cycle component (LCOETotal fuel cycle) of the levelised cost electricity (LCOE) for NPPS under different capacity, different cycle routes and different discount rate was calculated. In addition, the sensitivity analysis was made to identify the most influential parameters in the final price. Also, the breakeven price of uranium was calculated to be 130 $/kgU (59 $/lb) for PRR fuel cycle with a fleet generating 100 TWh/year at 4% discount rate and 74 $/kgU (34 $/lb) at 2% discount rate with reference to the OTC option. Then, the uncertainty analysis was made by EXCEL&Crystal software.
