Scenery with eight, 120 metres high cooling towers at the nuclear power plant in Jaslovské Bohunice has visibly changed. To this day, the first of four shutdown cooling towers reaches the height of approximately 35 metres. Its demolition started on the 2nd of October 2017 and demolition works were temporarily stopped only for 5 working days due to fog or heavy snow. During the demolition works, visibility between the operator and demolition location cannot be less than 30 metres.
This year, the crane at the first cooling tower will be dismantled and then transferred to the cooling tower No. 2. Transfer is planned in a week from 10th of January – 15th of January 2018. Demolition of the cooling tower No. 1 will then continue using the standard ground-based demolition machinery. All internal parts of the cooling tower No. 2 are currently demolished. The concrete footing for the tower crane is prepared in it. To build the concrete footing, approximately 200 m3 of concrete were used. Demolition of the second cooling tower should commence in the second half of January 2018. At present, internal parts are demolished in the cooling towers No. 3 and No. 4.
Conventional method of demolition is used for the V1 NPP cooling towers demolition. This method involves gradual demolition of the towers. Construction waste from the cooling towers is not radioactive and from the viewpoint of the environment protection it is not hazardous. The aim of the cooling towers demolition project is to minimize the waste volume to the largest extent possible or recycle it. For this reason, demolished concrete material will be processed in a crushing plant and then used for backfilling after demolition. In this area, landscaping and grassing will be done.
Consistent removal of four cooling towers forms an inseparable part of the V1 NPP decommissioning process. Shutdown of both units of the V1 nuclear power plant was a commitment of Slovakia resulting from negotiations on access of Slovakia to the European Union. The process of shutdown started in 2006 and 2008 respectively, based on the Government Decree No. 801/1999 of the 14th of September 1999.
