Russian troops have detained Ihor Murashov, director of Ukraine's Zaporizhzhia nuclear power plant, state nuclear regulator Enerhoatom said, as per a media report.
It says Murashov was held as his car was on its way from the facility to the nearby town of Enerhodar on Friday.
He was then blindfolded and taken to an unknown location, Enerhoatom says, BBC reported.
Russia has not commented. Moscow seized Europe's biggest nuclear plant in March, and kept on its Ukrainian staff.
Both Ukraine and Russia accuse each other of repeatedly shelling the plant, amid global concerns that this could lead to a major radiation incident in Europe.
Enerhoatom president Petro Kotin said that Murashov "bears main and exclusive responsibility for the nuclear and radiation safety" of the nuclear plant.
He said Friday's detention "jeopardises the safety of operation of Ukraine and Europe's largest nuclear power plant".
Kotin appealed to the International Atomic Energy Agency to demand the immediate release of the plant's chief, accusing Russia of "nuclear terrorism".
The six-reactor Zaporizhzhia nuclear plant is located near Enerhodar, in the occupied part of Ukraine's southern Zaporizhzhia region.
Ukraine says Russian troops are using the station as a military base and that employees are in effect held at gunpoint. Moscow denies the claim.
On Friday, Russian President Vladimir Putin declared the annexation of the Zaporizhzhia, Kherson, Donetsk and Luhansk regions - a move widely condemned by Ukraine and the West.
Moscow does not fully control any of the four regions in Ukraine's east and south, BBC reported.

At an annual memorial, Guterres warned of the risk posed by crises in Ukraine, the Middle East and the Korean peninsula as he described the horrors endured by the Japanese city.
"Any attack to a nuclear plant is a suicidal thing," Guterres told a news conference in Japan, where he attended the Hiroshima Peace Memorial Ceremony on Saturday to commemorate the 77th anniversary of the world's first atomic bombing.
The nuclear plant, which is Europe's biggest, was captured by Russian forces in March shortly after the start of Moscow's invasion of Ukraine. Ukraine has accused Russia of deploying soldiers and storing ammunition and armoured vehicles there.
Captured by Russian troops in March but run by Ukrainian staff, Zaporizhzhia has been a hotspot in a conflict that has settled into a war of attrition fought mainly in Ukraine's east and south six months after Russia launched its invasion.
