Title:
METHOD AND DEVICE FOR REDUCING VIBRATION IN NUCLEAR REACTOR CONSTITUTIVE COMPONENT
Document Type and Number:
Japanese Patent JP2006017715
Kind Code:
A
Abstract:

To provide a device for reducing vibration in a constitutive component of a nuclear reactor by removing vibrational energy.

This device coupled operably with the constitutive component and containing a magnet 340 is operated in an inside of a conductive cylinder 330 to reduce the vibration in the constitutive component. One or more of eddy currents are generated to bring an attenuation function for removing the vibrational energy from the constitutive component by the operation, so as to change a vibration characteristic of the constitutive component. A spring mechanism 232 and a mass regulate the vibration characteristics of the constitutive component by introducing the attenuation function for removing the vibrational energy in the constitutive component.
