The best-estimated methodology is applied for CAP1400 LBLOCA. Based on the sampling and calculation results, the influence of uncertainty parameters including plant initial conditions parameters, core power distribution parameters, global system thermal-hydraulic parameters and local hot rod parameters are evaluated. The major uncertainty parameters are figured out. Moreover, all uncertainty parameters considered in CAP1400 LBLOCA are ranked by their influences. The analysis results show that the break area, relative power of middle third of core, the accumulator initial pressure give the most contribution to PCT of CAP1400 LBLOCA. The uncertainty parameters could be optimized according this paper in the future.
