October 31, 2013 the first block of Ventilation Stack (VS-2) of ChNPP 2 generation has been dismantled. Weight of the dismantled block is 33 tons. The block is located at specially prepared site where it will be fragmented to move it in Unit 3 Turbine Hall for temporary storage.
Radiation situation parameters were monitored continuously during the work. Controllable parameters of the radiation situation do not exceed the design control levels. Additional radiation survey of dismantled block and its preparation for fragmentation is underway.
Dismantling of VS-2 will be performed by sequentially removing of separate blocks using the high capacity crane DEMAG. In total 7 blocks will be dismantled with weight 330 tons.
Planned completion date for VS-2 dismantling is December 10, 2013.
