A method for wireless acceleration sensor for detecting the dynamic response of the graphite reactor internals under earthquake conditions is proposed, and it can make a clear assessment of integrity of the graphite structure under seismic conditions. Test results show the consistence of the detection result of wireless acceleration sensor and the cable acceleration sensor detection when all the conditions for the seismic experiments are satisfied. The wireless detection technology avoids the disadvantages of high installation cost, and poor reliability and safety of the graphite structure detection system based on the traditional wired network.
