  Increasing amounts of spent nuclear fuel are stored in dry storage casks for
prolonged periods of time. To date no effective technology exists to re-verify
cask contents should this become necessary. We explore the applicability of
Coherent-Elastic Neutrino-Nucleus Scattering (CEvNS) to monitor the content of
spent nuclear fuel (SNF) from dry storage casks. SNF produces neutrinos chiefly
from $^{90}$Sr decays. We compare these results with what can be achieved via
Inverse Beta Decay (IBD). We demonstrate that at low nuclear recoil energies
CEvNS events rates exceed the IBD event rates by 2--3 orders of magnitude for a
given detector mass. We find that a 10\,kg argon or germanium detector 3 meters
from a fuel cask can detect over 100 events per year if a nuclear recoil
threshold under 100 eV can be achieved.
