Comparison between Simulation of Reduced Scale Vertical Concrete Cask under the Earthquake Effect and Experimental Result

Abstract:

The setup programme of dry storage of using spent fuel is that transportable storage canister (TSC) packing by using spent fuel placed in vertical concrete cask (VCC), then conveyed VCC from plant to site and put concrete pad. After VCC is in position, place the add-on-shell (AOS).This research analyses and simulate the behavior of VCC and AOC during earthquake by LS-DYNA which is dynamic transient structural analysis of finite element method. The main issue is the shaking response of VCC under earthquake while there is a hump on the bottom floor. From the result, the perturbation of dynamic stability of VCC and AOS have been occurred when the hump existed onto the floor. The construction specification of VCC/AOC bottom flatness should be considered
