President of Ukraine Petro Poroshenko said this in the course of events held to commemorate the Chornobyl disaster, an Ukrinform correspondent reported.
"I would like to express gratitude to our international partners. With their support, a new safe confinement has already covered the old sarcophagus. The process of lifting the arch to its original position above the fourth power unit was completed in November 2016. We plan to put the confinement into operation in November of 2017," Poroshenko said.
The President stressed that after putting into operation "this guarantees a minimum of 100 years of safe use, and it will protect us, our children, grandchildren and great-grandchildren."
