Query: Does the nuclear spin relaxation rate in superconductors depend on
  disorder?   We calculate the relaxation rate of a nuclear spin in s-wave superconductor
with nonmagnetic impurities, including the strong-coupling effects. We show
that in a weakly disordered three-dimensional system the corrections due to
disorder are negligibly small.
