In terms of the heat treatment operating standards and heat treatment process for nuclear power control rod driving mechanism and reactor internal components,the analysis was conducted,in combination with heat treatment production experience.It is concluded that the types of heat treatment of control rod driving mechanism and reactor internal components are divided into stress relief heat treatment(i.e."dimensional stabilizing heat treatment"),heat treatment for improving material properties,annealing(including bright annealing),aging,local heat treatment,achieving the operating standards and processes that guide heat treatment of nuclear power control rod driving mechanism and reactor internal parts(components).
