This field is the main technical department of the power plant, including operation, maintenance, technical support, equipment management and other departments. Nuclear power plants also have nuclear safety departments and radiation protection departments. The overall bonus of the technical department is higher than that of the comprehensive department and the party building department, and the operation department of the nuclear power plant also needs three shifts. The nuclear power plant implements six shifts and three shifts, with a large class every 42 days, and each large class will arrange training courses for about 3 days. Operators need to work night shifts, which is hard, so they have shift allowance every month.
