Pir

Pir, or Pir (Post-Irradiation Recovery), is a process used to assess the durability of materials, particularly in nuclear reactors. It involves exposing a material to radiation and then allowing it to recover or stabilize over time. By studying how the material's properties change during this period, scientists can understand its long-term behavior, resilience, and potential for degradation. This information helps ensure that materials used in nuclear environments remain safe and effective throughout their service life. In essence, Pir provides insights into how materials perform and adapt after exposure to harsh radiation conditions.
