CONTROLLED ELASTOPLASTIC DAMPER FOR EQUIPMENT AND PIPELINES OF NUCLEAR POWER STATION REACTOR PRIMARY CIRCULATION CIRCUIT Russian patent published in 2012 - IPC F16F1/14 F16F7/12 F16F15/04 

FIELD: machine building.

SUBSTANCE: damper comprises hollow twin torsion made from alloy with memory effect. Said torsion is coupled with equipment and pipelines attachment bracket lever. Nuclear power station reactor floor bed accommodates vibration transducer connected with control unit and power supply. Smaller feed pipelines are connected with torsion and filled with heat carrier and communicated with heat and cold heat carrier bypass valves. Bypass valves are communicated via cable lines with control unit. Hot heat carrier bypass valve of the main circulation circuit is communicated via small feed pipeline with nuclear power station reactor outlet circuit. Cold heat carrier bypass valve is communicated with main circulation pump outlet circuit. Temperature transducer thermocouple is secured on torsion, connected with control unit by cable line.

EFFECT: high thermal capacity, efficient damping, reusability.
