In 2022, STUK’s operating expenses were EUR 40.2 million. About 42 pro cents (16.9 million) of the funding came from the taxpayers via the government budget. Almost one half (20.7 million) of the operating expenses was collected by STUK as regulatory oversight fees, of which 19.9 million came from the regulatory oversight of nuclear energy use and the rest from the control of radiation activities.
