1. Reasons for Amendment

This amendment aims to enhance safety by advancing the submission period of the periodic safety review report before the base date for review (every 10th anniversary of the issuance date of the operating license) to preemptively confirm the safety of nuclear power plants for the next 10 years, changing the submission period of the continuous operation safety review report to 10 - 5 years before the date of expiration of the design lifespan to secure sufficient review period by regulatory bodies and ensure that improvements such as facility improvement are carried out at an early stage.
