Zircalloy cladding is not commonly reused and neither is fission product zirconium, which could be used in cladding as its relatively weak radioactivity would be of no major concern inside a nuclear reactor. Despite its high yield and long live, Zr-93 is generally not deemed to be of major concern as it is not chemically mobile and emits little radiation.
In the context of nuclear reactors, zircalloy cladding typically does not get reused, and fission product zirconium is rarely used in cladding because its low radioactivity levels are insignificant within the reactor environment. Although Zr-93 has a high yield and long duration of activity, it is generally not viewed as a significant issue due to its chemical stability and minimal radiation emission.
