The degradation of control rods is investigated and the cracking mechanisms in a cladding tube near the tips is determined. Temperature and load analysis was carried out to obtain data on life time estimation for cladding tube cracking by absorber swelling of PWR RCCA rodlets. For operating temperature range, tensile and creep tests are also done. Based on the investigation the life estimation for cladding tube crackings by absorber swelling is shown.
