Merry-go-round

These are the tornado-looking anomalies, which can be found all over the world. A handy place early-on which you'll probably find naturally through following the story is North-East of Zalissya in front of the "Radiation Hazard Signs Storage" on the path.

There are enemies in the building nearby - kill them and grab a body. Bring it to the anomaly, use your bolt to trigger it and then as it starts to finish drop the body in it. Job done :)
