Fire out at Ukraine nuclear plant after Russian attack, officials say no radiation released

Ukrainian firefighters on Friday extinguished a blaze at Europe's biggest nuclear plant that was ignited by a Russian attack and no radiation was released, UN and Ukrainian officials said, as Russian forces pressed their campaign to cripple the country despite global condemnation.

The head of the United Nations' atomic agency said that a Russian "projectile" hit a training centre at the plant and that the Ukrainians have control of the reactor. Earlier reports indicated Russian control of the facility, located in Ukraine's south.

Ukraine's state nuclear regulator earlier said that no changes in radiation levels have been recorded so far after the Zaporizhzhia plant came under attack. International Atomic Energy Agency Director-General Rafael Mariano Grossi later said no radioactive material was released, but that two people were injured in the fire that broke out at the plant.

The attack caused worldwide concern — and evoked memories of the world's worst nuclear disaster, at Ukraine's Chornobyl.

The shelling of the plant came as the Russian military advanced on a strategic city on the Dnieper River near where the facility is located, and gained ground in their bid to cut the country off from the sea. That move would deal a severe blow to Ukraine's economy and could worsen an already dire humanitarian situation.

Initial reports conflicted over whether one or two fires broke out at the plant in the city of Enerhodar. Nuclear plant spokesperson Andriy Tuz told Ukrainian television overnight that shells fell directly on the facility, and set fire to reactor No. 1, which is under renovation and not operating, and to an administrative training building.

On Friday morning, officials only referenced a blaze at the training building when they said that all fires at the plant were out — which Grossi also confirmed. The regional military administration reported unspecified damage to the compartment of reactor No. 1, but said it does not affect the safety of the power unit.

The nuclear regulator said staff are studying the site to check for other damage.

Grossi confirmed Friday that the building hit was a training centre and "not part of the reactor." He said he did not know what hit the plant but called a "projectile" from Russian forces.

He said that only one reactor at the plant is operating, at about 60 per cent capacity.

The confusion itself underscored the dangers of active fighting near a nuclear power plant. It was the second time since the invasion began just over a week ago that concerns about a nuclear accident or a release of radiation materialized, following a battle at Chornobyl.

The regulator noted in a statement on Facebook the importance of maintaining the ability to cool nuclear fuel, saying the loss of such ability could lead to an accident even worse than 1986 Chornobyl disaster or the 2011 Fukushima meltdowns in Japan. It also noted that there is a storage facility for spent nuclear fuel at the site, though there was no sign that facility was hit by shelling.

The Zaporizhzhia regional military administration said that measurements taken at 7 a.m. local time Friday showed radiation levels in the region "remain unchanged and do not endanger the lives and health of the population." Nuclear officials from Sweden to China also said no radiation spikes have been reported.

"The fire at the (nuclear plant) has indeed been extinguished," Enerhodar Mayor Dmytro Orlov announced on his Telegram channel Friday morning. His office told The Associated Press that the information came from firefighters who were allowed onto the site overnight.
