摘要：

To verify the safety of the reactor, the limit of rod drop time for control rod drive line (CRDL) shall be set in the design of reactor. Only horizontal seismic load was considered in the seismic test and rod drop analysis research at present. In this paper analysis and test research on the effect of the rod drop under the vertical seismic load was conducted. The result shows that the vertical seismic load added the complexity of the rod drop, and the vertical seismic load would cause obvious effect on the rod drop time of the control rod. © 2017, Editorial Board of Journal of Nuclear Power Engineering.
