Abstract

Under the Coordinated Research Program on 'Intercomparison of LMFBR seismic analysis codes' organised by IAEA/IWGFR, benchmark analysis using the experimental data supplied by France, Italy and Japan have been carried out in order to verify and validate the computer codes developed for the core seismic analysis. In this context, the special purpose computer code 'CORE-SEIS' has been developed at IGCAR, Kalpakkam, which has many novel features so as model the complex phenomenon that are associated with the seismic motions of LMFBR subassemblies. The analysis has been performed for the following cases. Rapsodie (France) tests on free standing core in air and water. PEC (Italy) data on: i) tests with single PEC fuel subassembly (in air and water) ii) tests with a small cluster (7 and 19 subassemblies) in air and water. Monju (Japan) data on: i) impact and vibration tests on single subassembly ii) vibration tests on 37 subassembly cluster and 29 subassemblies in a row. Most of the experimental results are satisfactorily predicted by CORE-SEIS. The CORE-SEIS predictions also have shown good comparison with other core seismic analysis codes used in the CRP.
