Control rod cladding wear prediction method after control rod full lifting rod position adjustment

The invention relates to the technical field of control rod cladding wear prediction, and provides a control rod cladding wear prediction method after control rod full-lifting rod position adjustment in order to solve the problem that under the control rod full-lifting rod position adjustment condition, an existing method is difficult to predict the control rod cladding wear rate and the residual wall thickness. Comprising the following steps: predicting and calculating a reactor core wear rate under a full-lifting rod position adjustment condition; and predicting and calculating the residual wall thickness of the cladding under the condition of full-lifting rod position adjustment. The method can accurately and conservatively calculate the residual wall thickness of the control rod under any reactor core arrangement under the condition that the nuclear power plant adopts the measure of regularly adjusting the full lifting rod position of the control rod, and is used for guiding the reactor entering scheme de
