What Does IASCC Stand For?

IASCC stands for Irradiation Assisted Stress Corrosion Cracking

Irradiation Assisted Stress Corrosion Cracking (IASCC) is a material degradation phenomenon that occurs in certain metals and alloys, particularly in nuclear environments. It is characterized by the combined effects of radiation exposure and tensile stress leading to the formation of cracks in the presence of corrosive environments. IASCC poses significant challenges for the integrity and longevity of components used in nuclear reactors, where both radiation and corrosive conditions are prevalent. Understanding and mitigating IASCC is essential for ensuring the safe operation of nuclear facilities and prolonging the lifespan of reactor materials.
