A new class of topological superconductors, which are protected by nonsymmorphic crystalline symmetry, were theoretically proposed recently. In this class of topological superconductors, Majorana zero modes are protected by nonsymmorphic symmetry. In this work, we use Blonder-Tinkham-Klapwijk theory to study Andreev reflections in junctions consisting of a normal metal and a topological nonsymmorphic crystalline superconductor. Furthermore, we will analyze the Majorana zero mode signatures in Andreev reflection spectroscopy.
