Abstract

Protection Nets have been clarified as one of the countermeasures to protect facilities of Nuclear Power Plants against Tornado Missile. The capturing performance of the Net Protection System with Ring Nets has been c larified by free -fall test.This research proved, that analytical evaluation is thought to be efficient for the net system by multiple case of reproducing simulation of the free-fall test using a general purpose structural analysis program/L S-DYNA , and comparing the dynamic response about the impacting force and deformation of components with the test results.
