The International Atomic Energy Agency has outlined the scale of the damage caused by a drone strike and subsequent fires to the giant shelter built over the ruins of Chernobyl’s unit 4.

The agency said that investigations continue to determine the extent of the damage sustained by the arch-shaped New Safe Confinement (NSC) shelter following the drone strike on 14 February.

The impact caused a 15-square-metre hole in the external cladding of the arch, with further damage to a wider area of about 200-square-metres, as well as to some joints and bolts. It took about three weeks to fully extinguish smouldering fires in the insulation layers of the shelter.

n its update on the situation, the International Atomic Energy Agency (IAEA) said: “It took several weeks to completely extinguish the fires caused by the strike. The emergency work resulted in approximately 330 openings in the outer cladding of the NSC arch, each with an average size of 30-50 cm.

“According to information provided to the IAEA team at the site, a preliminary assessment of the physical integrity of the large arch-shaped building identified extensive damage, for example to the stainless-steel panels of the outer cladding, insulation materials as well as to a large part of the membrane – located between the layers of insulation materials – that keep out water, moisture and air.”

The main crane system, including the maintenance garage area, was damaged and it is not currently operational, the IAEA said. The heating, ventilation and air conditioning systems are functional but have not been in service since the strike. Radiation and other monitoring systems remain functional, the IAEA said. There has been no increase in radiation levels at any time during or since the drone strike.

IAEA Director General Rafael Mariano Grossi said: “We are gradually getting a more complete picture of the severe damage caused by the drone strike. It will take both considerable time and money to repair all of it.”

…………………………………………………………………………………The New Safe Confinement was financed via the Chernobyl Shelter Fund which was run by the European Bank for Reconstruction and Development (EBRD). It received EUR1.6 billion (USD1.7 billion) from 45 donor countries and the EBRD provided EUR480 million of its own resources.

On 4 March the EBRD allocated EUR400,000 from the administrative budget of the continuing fund for specialist-led damage assessment……………………………..https://www.world-nuclear-news.org/articles/chernobyl-shelters-drone-damage-includes-330-openings-in-outer-cladding
