In　order　to　consider　the　propagation　characteristics　of　the　source　in　the　probabilistic　seismic　hazard　analysis,　the　method　of　combining　stochastic　simulation　with　probabilistic　seismic　hazard　analysis　was　proposed,　considering　the　effect　of　source　mechanism,　path　and　site　effect,　and　could　get　more　accurate　uniform　hazard　spectrum　(UHS).　A　method　to　simulate　the　historical　earthquake　in　the　site-specific　of　the　nuclear　power　plant　(NPP)　and　develop　the　UHS　with　an　equal　rate　of　being　exceeded　was　proposed.　To　compare　the　NPP　seismic　performance　of　different　ground　motions　generated　by　existing　site　spectrum　(SL-2),　the　UHS　generated　by　the　safety　evaluation　report　and　the　US　RG1.60　spectrum,　three-dimensional　finite　element　model　was　created　to　dynamic　analysis.　The　results　show　that　the　response　of　different　spectra　to　the　structure　is　quite　different.　The　response　of　UHS　is　closer　to　SL-2　and　slightly　larger　than　the　SL-2,　but　UHS　is　less　than　US　RG1.60　spectrum.　The　UHS　based　on　stochastic　simulation　method　can　provide　a　reference　for　the　seismic　design　of　NPP.　©　2018,　Editorial　Board　of　Atomic　Energy　Science　and　Technology.　All　right　reserved.
