Predictive Study of CAP1400 Core Barrel Flow-induced Vibration-Parti: Turbulence induced Forcing Function

摘要

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 of the pressure vessel and its internals was conducted to study the flow induced vibration (FTV) characteristics. This paper describes the predictive study in calculating the core barrel vibration magnitudes and its successful comparison to the test measurements. It is noted that this is the first part, which describes the forcing function development and its successful comparison with the pressure pulsations measured from the scale model test, of a two-part series. The structural aspects, i.e., the core barrel vibration predictive study and their comparison with the test results, will be described in the second part of this series.
