Operations to open and soak two affected areas are in progress. An additional 21 rope access specialists are on standby. Three openings have been made, totaling approximately 2 square meters.
Three fire hoses are in operation, with continued soaking of the insulation and membrane. The situation is being monitored using a thermal imaging UAV.
The radiation levels at the Chornobyl NPP industrial site remain within permissible limits. On the NSC roof, at the worksite, the radiation level is 186.7 µSv/h.
A total of 85 SES personnel and 18 units of equipment are involved in the response.
