Abstract

PURPOSE: To heighten the earthquake resistance of pipe, by developing a vibration- proof device of high reliability for high temperature and radioactivity.
CONSTITUTION: When a supported structure undergoes acceleration by earthquake, a liquefied metal 13 in cylinder chmbers 1a, 1b is held from flowing into gaps by a labyrinth seal 2-1, 2-2 between a cylinder 1 and a piston 2 and another labyrinth seal 1-1, 1-2 between the cylinder and a suspended rod 3. The resistance of thin feed/discharge passages 14, 15 rises against the rapid flow of the liquefied metal 13 to stop the flow. Therefore, the motion of the piston 2 is hindered. Shield members 5, 6 and annular radiator fins 10 block r-rays emitted from a radiation source to protect each part from radiation damage. The shield member 6, the fins 10 and other fins 12 transfer to the atmosphere the heat of part heated by the r-rays
