Abstract:
11UKT in Tian Wan nuclear power station is the temporal storehouse of radioactive solidification waste.When operator directly operates the crane to load in the storehouse,the operator will be subjected to nuclear radiation,with intensive workload and poor orientation precision.In this paper,the crane for the storehouse of radioactive solidification waste 11UKT is improved technically,based on the laser measurement instrument,variable frequency speed regulation technology and PLC.After the improvement,the orientation precision of the crane is up to ±2mm.Operation is computerized,and the operator can complete the orientation by hitting the mouse.It may reduce the workload of operators,and thus avoid excessive nuclear radiation to the operators.
