Method for calculating generating capacity and capability factor of nuclear power plant unit

The invention particularly relates to a nuclear power plant unit generating capacity and capability factor calculation method. The method comprises the steps of obtaining nuclear power plant overhaul planning data; and according to the nuclear power plant overhaul planning data, calculating and displaying the generating capacity and the capacity factor of each unit in each year and the total generating capacity and the average capacity factor of the multiple units in each year in the nuclear power plant overhaul planning. The invention also relates to a system for calculating the generating capacity and the capability factor of the nuclear power plant unit, computer equipment and a computer readable storage medium. According to the method, the generating capacity and the capacity factor of each year of each unit and the total generating capacity and the average capacity factor of the multiple units of each year in the nuclear power plant overhaul planning data are efficiently and accurately calculated and are
