CNTs can protect metals against radiation damage - Materials Today
One of the main reasons for limiting the operating lifetimes of nuclear reactors is that metals exposed to the strong radiation environment near the reactor core become porous and brittle, which can lead to cracking and failure. Now, a team of researchers at the Massachusetts Institute of Technology (MIT) and elsewhere has found that, at least in some reactors, adding a tiny quantity of carbon nanotubes (CNTs) to the metal can dramatically slow this breakdown process.
