Comparative study of transient thermal–hydraulic characteristics of SCWRs with different core design
چکیده انگلیسی

The comparative studies of transient flow characteristics and the consequent safety performance for SCWRs with different flow path designs have been performed. Three different SCWR concepts SCWR-M, American SCWR and SSCWR are respectively selected as the representations of multi-pass core, one-pass core with water rods and one-pass core without water rods. The comparative analyses of loss of flow accident (LOFA) are carried out for the three SCWR concepts by TACOS code. The flow rate and cladding temperature behaviors are compared to each other. The results show that the SCWR-M and the American SCWR concepts have more complicated transient flow characteristics than the SSCWR. Under the assumed condition in the work, inverse flow occurs both in the SCWR-M and the American SCWR following the LOFA. The evaluation of the effect of AFS flow rate indicates that the flow path design of the SCWR-M would require larger injection flow rate than the other two concepts to mitigate the LOFA.


► Three SCWR concepts with different flow path designs are investigated.
► The comparative analyses of loss of flow are carried out for the three SCWRs.
► Inverse flow occurs both in the SCWR-M and the American SCWR.
► SSCWR has the simplest flow mode during the transient.
► The SCWR-M would require the largest injection flow rate.
