The motivations for the Zero degree calorimeter (ZDC) use at MPD are discussed. ZDC is intended for the measurements of the geometry (centrality) and the reaction plane of nucleus-nucleus collisions. Two identical calorimeters would be placed at the opposite sides of MPD to detect the non-participating fragments or spectators. ZDC is modular hadron calorimeter with high granulation in both transverse and longitudinal directions. Each ZDC module consists of the lead/scintillator sandwiches with the sampling ratio 4:1 that ensures the compensation condition of the hadron calorimeter. The light readout of the ZDC would be done by novel silicon photomultipliers, SiPMs with high pixel density and large dynamic range. The parameters of the calorimeter are discussed.
