The protective shield over the Chornobyl disaster nuclear reactor in Ukraine, which was hit by a drone in February, can no longer perform its main function of blocking radiation, the International Atomic Energy Agency (IAEA) has announced.
In February a drone strike blew a hole in the “new safe confinement”, which was painstakingly built at a cost of €1.5bn ($1.75bn) next to the destroyed reactor and then hauled into place on tracks, with the work completed in 2019 by a Europe-led initiative. The IAEA said an inspection last week of the steel confinement structure found the drone impact had degraded the structure.
The 1986 Chornobyl explosion – which happened when Ukraine was under Moscow’s rule as part of the Soviet Union – sent radiation across Europe. In the scramble to contain the meltdown, the Soviets built over the reactor a concrete “sarcophagus” with only a 30-year lifespan. The new confinement was built to contain radiation during the decades-long final removal of the sarcophagus, ruined reactor building underneath it and the melted-down nuclear fuel itself.
The IAEA director general, Rafael Grossi, said an inspection mission “confirmed that the [protective structure] had lost its primary safety functions, including the confinement capability, but also found that there was no permanent damage to its load-bearing structures or monitoring systems”.
