The invention provides a nuclear emergency
system of a
nuclear power plant, and belongs to the technical field of
nuclear power plant emergency planning and preparing. The
system comprises portable individual emergency devices, a fixed
nuclear radiation monitoring device, an emergency refuge and a control center. The portable individual emergency device and the fixed
nuclear radiation monitoring device can position and measure current
radiation data and send the data to the control center. The control center judges whether leakage happens or not, confirms the accident location and
radiation range, and plans the retreating and emergency refuge
route according to positions of all workers through summarization and analysis, and sends the information to the corresponding portable individual emergency devices to be displayed on a map through display modules, and safe retreating of the workers is ensured. The
system is simple in structure, complete in function, rapid, efficient and high in
safety coefficient, greatly improves nuclear emergency reaction capacity and increases the
survival rate of the workers on site, and meanwhile can be used as a nuclear emergency
command system of the
nuclear power plant.
