Abstract: RED-100 is a two-phase emission detector with an active volume containing 126~kg of liquid xenon. The detector was exposed to the antineutrino flux of about $1.4 \cdot 10^{13}~$cm$^{-2}$s$^{-1}$ at a distance of 19~m from the 3.1~GW Kalinin Nuclear Power Plant (KNPP) reactor core. The comparison of data from 331~kg$\cdot$days with the reactor on and 106~kg$\cdot$days with the reactor off shows no statistically significant excess and allows to put constraints on coherent elastic interactions of antineutrinos with xenon nuclei.
