Seismic Proving Test of Heavy Component With Energy Absorbing Support: Proving Test Results

The Seismic Proving Test of Heavy Component with Energy Absorbing Support has been conducted to prove the reliability of advanced seismic technology, supporting heavy component such as PWR Steam Generator with large capacity energy absorbing supports. This paper introduces the result of the proving test, using 1/2.5 scale model of PWR Steam Generator supported by Lead Extrusion Damper (LED), conducted on 2000–2001. This project has been conducted by the Nuclear Power Engineering Corporation (NUPEC) since 1995, using a large-scale, high-performance shaking table at Tadotsu Engineering Laboratory under the sponsorship of the Ministry of Economy Trade and Industry. Up to 2.9 S₂ (extreme design earthquake), LED showed stable energy absorbing performance and Steam Generator- primary piping system indicate no meaningful damage.
