Nuclear power plant control rod assembly cladding single-point wear relieving method

The invention relates to the technical field of nuclear power plant control rod assembly cladding single-point abrasion, and provides a nuclear power plant control rod assembly cladding single-point abrasion relieving method which comprises the steps that whether control rod full lifting rod position adjustment needs to be carried out or not is judged; determining an applicable object of the full-lifting rod position adjustment of the control rod; determining an upper limit of full-lifting rod position adjustment of the control rod; determining the lower limit of control rod full-lifting rod position adjustment; determining the minimum adjustment step number of the full lifting rod position of the control rod; determining an adjustment interval of a control rod full-lifting rod position; determining the adjustment period of the control rod full-lifting rod position; and implementing full-lifting rod position adjustment of the control rod. Long-term abrasion of the control rod at the same position is avoided b
