Structural, thermal analyses and safety test evaluation for dry storage system

This is contract result report conducted by KAERI under the contract with NETEC for structural and thermal evaluation of dry storage system for spent nuclear fuel. This report contains the thermal, structural and seismic tests and analyses for verification of safety evaluation for storage cask. Thermal tests for storage cask were conducted under normal, off-normal and accident conditions. There were good agreements between the thermal analysis and test results. Structural tests were conducted under drop and turn-over conditions. The measured strain and acceleration from the tests are slightly lower than the analysis results. The results of the seismic test also accord with the analysis results. Therefore, it was shown that the analysis method and procedure were successfully established to evaluated the safety for the storage cask. Safety analysis procedures has been established to evaluate the thermal, structural and seismic safeties of storage cask
