But in a statement issued on Wednesday, the International Atomic Energy Agency (IAEA) sought to calm fears.

"Due to time elapsed since the 1986 Chernobyl accident, the heat load of the spent fuel storage pool and the volume of cooling water contained in the pool is sufficient to maintain effective heat removal without the need for electrical supply."

Meanwhile, radiation levels around the Zaporizhzhia nuclear power plant - the largest in Europe - and which was seized by Russian forces last week, are said to be normal.

Repairs are being carried out on a block damaged by fighting, Petro Kotin, the head of state nuclear firm Energoatom, said.
