Study on the Difference between ORIGEN-S and ORIGEN2

Abstract:

The ORIGEN-S and ORIGEN2 codes were described in this paper, which were used to calculate the source term in the reactor core. The differences between ORIGEN-S and ORIGEN2 codes were compared and analyzed. The most significant difference was the methodology used to prepare and provide the neutron data for the codes, which directly affected the accuracy of calculation results of the ORIGEN2 code under different values of the parameters. Finally, the radioactivity of the actinide and fission products was calculated by changing the fuel enrichment, burnup and specific power of PWR, which was used to make quantitative analysis of the difference of results calculated by ORIGEN-S and ORIGEN2 and verify the degree of influence of various parameters on the results.
