as soon as  you ask who would do this all things must be considered, like who is loosing, who has attacked nuke facilities in the past, and what would this accomplish;

The protective shelter over the reactor at Chernobyl Nuclear Power Plant can no longer guarantee radiation containment, the International Atomic Energy Agency (IAEA) has said. The agency added that urgent major repairs are now required.

The warning follows an inspection prompted by a drone strike in February, which marked the first major attack on the shelter. Moscow said the strike was a provocation orchestrated by Kiev, while the Ukrainian government blamed Russia.

The strike had pierced the outer shell of the massive steel arch known as the New Safe Confinement (NSC) and triggered a fire. While the initial damage did not cause a radiation leak, the new assessment shows the structural breach has degraded the shelter’s ability to contain nuclear material.

The IAEA confirmed on Friday that the NSC, a 36,000-tonne steel structure built over the destroyed Unit 4 reactor at Chernobyl, “had lost its primary safety functions, including the confinement capability.” ..........more..........
