Post Irradiation Examination (PIE) refers to the analysis and evaluation of nuclear materials, particularly spent nuclear fuel and irradiated materials, after they have been subjected to neutron irradiation in a reactor. This examination is crucial for understanding the changes that occur in materials due to irradiation, including chemical, structural, and isotopic alterations.
