Аnalysis of seismic and vibration capacities of the WWER-1000 control rod drive system
Transactions of the 14th SMIRT, Lyon, France, August 1997
This paper presents the results of experimental and computer analyses of seismic margin capacity and operability under abnormal vibration of PWR (WWER) Control Rod Drive System (CRDS). A special PC computer program “SEISM-2000” for non-linear dynamic analysis of CRDS has been developed and verified regarding to shaking table experiment of the CRDS ¼ scale model. The result of experiment and analysis show high sensitivity of the PWR CRDS operability to seismic and vibration loading.
