Birds, including swans, swim in a water reservoir of the Khmelnytskyi Nuclear Power Plant (KhNPP) near the town of Ostroh, Ukraine February 17, 2021. The reservoir, which turned into a local tourist spot, attracts dozens of swans every winter as it never freezes over due to the warm waters discharged from the plant.
