REGIONAL SEISMIC MONITORING NETWORK FOR NUCLEAR POWER PLANT SITES Russian patent published in 2023 - IPC G01V1/00 

FIELD: seismic monitoring systems.

SUBSTANCE: invention can be used for seismic monitoring of operating nuclear power plants. The regional network of seismic control contains a centre for collecting and processing information, as well as points for recording and transmitting seismic data, located at the sites of operating nuclear power plants. Each of the points of registration and transmission of seismic data is made in form of a container installed on the foundation. Inside the container there is a pedestal buried in the ground below the level of seasonal freezing. The pedestal is covered with a sand cushion on four sides. An accelerometer and a velocimeter are placed on the pedestal. The data from the accelerometer and velocimeter are sent to a recorder located inside the container, and then, using an external antenna, they are transmitted to the information collection and processing centre in the form of accelerograms and velocigrams in real time.

EFFECT: increased reliability of seismic monitoring in real time.
