Dec 29 (Reuters) - An external power link has been restored to the Russian-held Zaporizhzhia nuclear power station in Ukraine after the completion of repairs, the plant's Russian management said on Monday.
A statement said the line had been put out of action by "fire from the Ukrainian armed forces". Repairs were carried out with monitors present from the U.N. nuclear watchdog, the International Atomic Energy Agency. It said the situation at the plant was under control, with normal radiation levels.
The station is connected to the power grid by two lines -- the second had remained in operation through the repair work.
In September and October, the plant was without external power for 30 days, relying on backup diesel generators, until a damaged line was reconnected during a local ceasefire arranged with the IAEA's help.
Russian forces seized the nuclear plant, Europe's largest, in the early weeks of Moscow's invasion of Ukraine and each side regularly accuses the other of actions endangering safety there.
The plant is not producing electricity but relies on external power to keep nuclear fuel cool and avoid a meltdown.
The future of the plant's operations is one of the sticking points in talks to resolve the nearly four-year-old conflict pitting Moscow against Kyiv.
Almost all countries consider that it belongs to Ukraine but Russia says it is owned by Russia and a unit of Russia's state-owned Rosatom nuclear corporation runs the plant.
Ukrainian President Volodymyr Zelenskiy said in December that the U.S. had proposed joint trilateral operation of the nuclear power plant with an American chief manager.

A nuclear power plant is a facility that generates electricity using nuclear reactions. It relies on nuclear fission to produce heat, which is then used to generate steam that drives turbines.
External power refers to the electricity supplied to a nuclear power plant from the grid, which is essential for cooling systems and maintaining safety protocols.
The IAEA is an international organization that promotes the peaceful use of nuclear energy and aims to prevent the proliferation of nuclear weapons. It provides regulatory oversight and safety standards for nuclear facilities.
Radiation in nuclear power refers to the energy emitted from nuclear reactions, which can be in the form of particles or electromagnetic waves. Monitoring radiation levels is crucial for safety.
