What is Thermal Fatigue in Reactor Piping Analysis about?
Thermal fatigue case studies document three cases of thermal fatigue cracking: 1) Circumferential cracking in 347 stainless steel moderator piping due to fluctuating cool zones creating thermal stress. 2) Crack in desuperheater piping due to cyclic wetting of surface from boiler feedwater sprayer creating thermal stress variations. 3) Desuperheater crack located 1.8 diameters from midpoint in high stress zone, caused by improper atomization of boiler feedwater at nozzle onto pipe wall.
