The seismic monitoring system is set up to preserve the 10MW High Temperature Reactor running normally or can be safely shut-down under the seismic status.The system is deigned for unattended station.This system is composed of high sensibility accelerometer,high reliability industry control unit(ICU) and ripe software for seismic analysing.It also uses new techniques in seismic data processing.Nine time history acceleartion signals in three positions are provided to this system.The peak accelerate value will be computed out after the system confirmed the seismic condition.The master-control room will get alarm signal with sound and light as the peak accelerate value above the threshold value.The system will also calculate computing response spectrum and design response spectrum.After the comparison with this two value and theory response spectrum,a final seismic report will be printed.With performance test on the MTS vibrating table of Tongji University,It has shown that Ⅰ type seismic design bases can be carried out with such system.The performance of this system is proved to be better than the assembly unit of many other seismic monitoring instruments.
