After three years of the power plant operation, we were asked to inspect the actual condition of the supporting steel structures, reactors and related flue gas ducts for units 1 and 2. These structures were designed by our company in 2019. In particular, the actual state of the structure was checked, whether there is no degradation of the structures, whether the elements of the structure were not released and, in particular, whether there were any unauthorized modifications of the structures during operation. Finally, a report on the inspection including photo documentation was prepared.
