Abstract: The reactor control rod drop time is an important parameter for the safety analysis and significant to the power plant safe operation. In order to get the control rod drop time history, in this paper, the kinetics equation and calculation Method is established. The complicated fluid and mechanical friction forces during rod drop course are described and analyzed in detail, and the drop time is deduced. The comparison of the calculation results and relative validation tests showed that the calculation result is conservative and reliable.
