September 11, 2022, at 03:41 am, ZNPP power unit No. 6 was disconnected from the grid. Arrangements for its cooling and transfer to a cold state are underway.
Over the past three days, the 6th power unit has been operating in an island mode powering exclusively the ZNPP in-house needs at a critically low capacity level (from 114 to 140 MW), since all transmission lines linking the Zaporizhzhya NPP to the Ukrainian power system were damaged due to russian shelling.
Yesterday evening, after one of these transmission lines was restored to its operational capacity, it became possible to power the ZNPP's in-house needs from the energy system of Ukraine. Therefore, a decision was made to shut down power unit No. 6 and transfer it to the safest state – cold shutdown.
In case of repeated damage to the transmission lines linking the facility to the power system, the risk of which remains high, the ZNPP's in-house needs will be powered by diesel generators, the service life of which is limited by the technological resource and the amount of available diesel fuel.
SE «NNEGC «Energoatom» takes all possible measures to organize the supply of additional batches of diesel fuel to the ZNPP.
In order to prevent an emergency situation at the power plant, it is necessary to stop the russian shelling of the transmission lines linking the ZNNP to the power system and establish a demilitarized zone around it. After that, it will be possible to repair the transmission lines, to ensure the connection to the grid and further safe operation of the ZNPP.
