Ukrainian President Volodymyr Zelenskiy said the world narrowly avoided a radiation disaster as electricity to Ukraine’s Zaporizhzhia nuclear power plant was cut for hours due to Russian shelling in the area.
A failure at the Zaporizhzhia plant could “kill hundreds or thousands of people, and damage environmentally a far larger area reaching into Europe,” Paul Bracken, a national security expert and professor at the Yale School of Management said.
Moscow denied UKraine’s allegations.
Zelenskiy said Russian shelling on Thursday sparked fires in the ash pits of a nearby coal power station that disconnected the reactor complex, Europe’s largest such facility, from the power grid.
Back-up diesel generators ensured power supply that is vital for cooling and safety systems at the plant, he said, praising the Ukrainian technicians who operate the plant under the gaze of the Russian military.
“If our station staff had not reacted after the blackout, then we would have already been forced to overcome the consequences of a radiation accident,” he said in an evening address.
“Russia has put Ukraine and all Europeans in a situation one step away from a radiation disaster.”
Vladimir Rogov, a Russian-appointed official in the occupied town of Enerhodar near the plant, blamed Ukraine’s armed forces for a fire in a forest near the plant.
He said towns in the area lost power for several hours on Thursday.
“This was caused by the disconnection of power lines from the Zaporizhzhia nuclear power station as a result of provocations by Zelenskiy’s fighters,” Rogov wrote on Telegram.
“The disconnection itself was triggered by a fire and short circuit on the power lines.”
Ukrainian state nuclear company Energoatom said it had been the first complete disconnection in the plant, which has become a hotspot in the six-month-old war.
Russia invaded Ukraine in February, captured the plant in March and has controlled it since, although Ukrainian technicians still operate it.
The United Nations is seeking access to the plant and has called for the area to be demilitarised. International Atomic Energy Agency (IAEA) officials are “very, very close” to being able to visit Zaporizhzhia, agency Director-General Rafael Grossi said on Thursday.
Russia and Ukraine have accused each other of shelling the site, fuelling fears of a nuclear disaster.
Nuclear experts have warned of the risk of damage to the plant’s spent nuclear fuel pools or its reactors. Cuts in power needed to cool the pools could cause a disastrous meltdown.
Paul Bracken, a national security expert and professor at the Yale School of Management, said the concern was that artillery shells or missiles could puncture the reactor walls and spread radiation around potentially a large area, much like the 1986 accident involving the Chornobyl reactor.
“Russian Roulette is a good metaphor because the Russians are spinning the chamber of the revolver, threatening to blow out the brains of the reactor all over Europe,” Bracken said.
