The Treaty on the Non-Proliferation of Nuclear Weapons (NPT) requires non-nuclear weapon states to exclusively utilize nuclear materials and technologies for peaceful purposes. It also permits the International Atomic Energy Agency (IAEA) to establish safeguards for the purpose of verifying compliance with the NPT's obligations. In the context of emerging reactor designs, particularly the development of Small Modular Reactors (SMRs), the enhancement of existing safeguards and the examination of novel safeguards are of particular importance. By using the example of a container loaded with spent nuclear fuel, this simulation-based feasibility study demonstrates that the use of cosmic muons makes it possible to obtain information about a container with the muographic application of an antineutrino detector. Moreover, the energy of the muons can be analyzed to ascertain the contents of the container, particularly the materials within, by determining their density. The insights gained from this analysis will be further developed to apply them to the context of SMRs, integrating them with other verification technologies.
