On the 12th of November 2013 the fifth block (B-5) of the ChNPP II Generation Ventilation Stack (VS-2) weighting 48 tons was dismantled.
SIP PMU “New Ventilation Stack” Project Manager Vitaliy Shurygin noted that works on VS-2 are unique, because they are carried out under conditions of ionizing radiation and radioactive contamination, as well as in confined spaces in the area with a large number of overhead passes, buildings of different purpose and transportation lines. With the objective to reduce the dismantling time, it is performed in larger units by the crane with lifting capacity of 1,600 tons.
Fragmentation of the previously dismantled blocks is underway within the specially prepared areas. The monitored radiation parameters do not exceed the design-based reference levels.
