Abstract: In a pressurized water reactor operation method, a fuel assembly including first fuel rods that operates for a preset first operation time and second fuel rods that operates for a second operation time longer than the first operation time is prepared. An operation schedule of a pressurized water reactor is created by mixing the first operation time of the first fuel rods and the second operation time of the second fuel rods. The pressurized water reactor operates by repeating the operation schedule.
