As described in Part 1 of this paper, [1], CAP1400 is a 1400 MWe pressurized water reactor developed by SNERDI to be the next series of nuclear power plants in China. As a part of the feasibility study, a 1/6 scale model test, conducted in Chengdo, China, of the CAP1400 pressure vessel and its internals was carried out to study the flow induced vibration (FIV) characteristics.
This paper describes the predictive study on the structural responses of the core barrel vibration with particular emphasis on using the “Fourier node” method in modeling the hydrodynamic mass effect. It is noted that this is the second part of a two-part series and is focusing on the structural response calculation using the forcing functions described in Part 1, [1], and the comparison with the measured data.
