The probabilistic safety assessment (PSA) model of the third generation nuclear power technology (AP1000) is built with CAFTA code

while the RiskSpectrum code is used in our institute.Based on the analysis of the data files of the two codes

the conversion code CAFTA2RS is developed to extract information from the PSA model built with CAFTA

modify the data format that incompatible with RiskSpectrum

convert the gate type

such as AANB

EQU and so on

to the gate type acceptable with RS

and finally convert the PSA model from the format of CAFTA code to the format of RiskSpectrum code automatically.
