ZAPORIZHZHIA - UN inspectors arrived at a Russian-held nuclear plant in southern Ukraine Thursday despite an early shelling attack, as the ICRC warned the consequences of a strike on the facility could be “catastrophic”. After crossing the frontline into Russian-held territory, the 14-strong team from the International Atomic Energy Agency (IAEA) reached the facility around 3:00 pm, the agency said on Twitter. “IAEA’s support and assistance mission to #Zaporizhzhya (ISAMZ) led by Director General Rafael Grossi has just arrived at Zaporizhzhya nuclear power plant to conduct indispensable nuclear safety and security and safeguards activities,” it said. Wearing bright blue flak jackets and helmets, they had vowed to press ahead to reach Europe’s biggest nuclear facility despite early-morning shelling in the area that forced the closure of one of its six reactors. Energoatom, Ukraine’s nuclear agency, said it was “the second time in 10 days” that Russian shelling had forced the closure of a reactor. It said the plant’s emergency protection system kicked in shortly before 5:00 am (0200 GMT), shutting reactor five, “due to another (Russian) mortar shelling” and that a backup power supply “was damaged” in the attack. The area around the plant, which lies on the southern banks of the Dnipro River, has suffered repeated shelling, with both sides blaming the other, sparking global concern over the risk of an accident.
