The invention belongs to the technical field of nuclear power plant equipment reliability, and particularly relates to a preventive maintenance project optimization method for a nuclear power plant. Comprising the following steps: step 1, according to the number of preventive maintenance item setting conditions of a nuclear power plant and equipment fault conditions occurring during daily operation of various types of equipment, determining the type of equipment which is preferentially subjected to preventive maintenance optimization; 2, collecting actual fault data of the selected equipment type; and step 3, according to the historical reliability data of the equipment, evaluating the prevention effect of the current preventive maintenance on the equipment fault and the like. The method has the beneficial effects that the actual reliability data of a certain type of equipment of the nuclear power unit is subjected to statistical analysis, the preventive maintenance items and the preventive maintenance period
