Experimental and computer analyses of control rod drive systems seismic capacity
- 1. CKTI-Vibroseism (CVS), St. Petersburg (Russian Federation)
Description
The experimental and computer analyses of the 1/4 scale Control Rod Drive System (CRDS) model of WWER-440 reactor has been carried out. The experimental study has been undertaken on CVS 20 ton's capacity shaking table with modeling operability of CRDS during earthquake and operational vibration. A special PC computer program has been developed for evaluation of CRDS seismic and vibration margins. The program enables estimation of different nonlinear effects in bearings and gaps of CRDS including shocks and friction that highly influence on dynamic capacity of CRDS. The results of these investigations are presented in this paper. (author)
