This is not entirely correct, alpha and beta radiation damage the crystaline and quasi-crystaline structures of metals and other materials Even when the reactors themselves, generally rest on light or heavy water, the steel, titanium and other metals and materials nearby the pellets or rods suffer greatly as a consequence of radiation, so it is not a matter of just neutron degradation, but a generalized problem of the physical interaction between radiation and the molecular structures of the materials Sadly for my case, my materials science course on University was very, very weak, but last year I found this MITOpenCourse which covers this topic on detail, I would highly recommend it to absolutely everyone interested on the topic https://www.youtube.com/watch?v=CjZjVUWMEz0 https://www.youtube.com/watch?v=CjZjVUWMEz0
