摘要：

The purpose of this dynamic characteristic test is to verify that the damping ratio used in the seismic analysis of the battery connection cable that constantly stores the emergency power of a nuclear power plant is 5 % or higher, and to confirm that the structural integrity of the cable supplied to the nuclear power plant is safe. The dynamic characteristic test method of the cable was performed using the same sample as the cable installed in the battery for a nuclear power plant, and the dynamic characteristic test was performed with reference to the Korean standard (KS B ISO 7626 [1, 2, 3], KS I ISO 10846 [4], KS M 6665 [5]). The test results proved that the damping ratio of 5 % applied to the seismic analysis of cables so far is reliable.
