The work of the Zaporizhzhya NPP was completely stopped
The plant will be safely brought into cold shutdown mode. Energoatom explained that the previously damaged communication lines were restored, after which it became possible to power the nuclear power plant from the energy system of Ukraine and turn off the last unit 3/15/756628827687153.jpg 673w” media=”(max-width: 320px) and (-webkit-min-device-pixel-ratio: 2), (max-width: 320px) and (min-resolution: 192dpi) ” >
< p>The last operating unit at the Zaporozhye NPP— sixth— was stopped, according to the message of the Ukrainian Energoatom, under whose control the nuclear power plant is formally located.
This was also confirmed in a comment to Interfax by advisor to the head of the Rosenergoatom concern; Renat Karchaa.
“The unit is stopped, it is currently transitioning to a cold state,” — he noted, adding that the shutdown was carried out in a soft, safe mode.
In Energoatom; clarified that the power unit was turned off on the night of September 11 at 3:41. Preparations are underway for its cooling and transfer to a cold state.
For the past three days, the sixth power unit has provided only the needs of the nuclear power plant itself, operating at a critically low level (from 114 to 140 MW), since the lines of communication with Ukraine were damaged due to shelling, Energoatom said.
«Last night, after the resumption of operation of one of these communication lines, power supply for the ZNPP's own needs became possible from the energy system of Ukraine. Consequently, it was decided to turn off power unit No. 6 and transfer it to the safest state— cold stop»,— said in the message of the state company.

They explained that in the event of repeated damage to communication lines, the ZNPP will be powered by diesel generators. Their service life is limited by the technological resource and the volume of available diesel fuel. In “Energoatom” assured that they are taking all possible measures to supply additional batches of fuel to the station.
The state company called for the creation of a demilitarized zone around the station and an end to the shelling, which it blames on Russian troops. After that, they say, it will be possible to carry out repairs and safely restore the operation of the nuclear power plant. Russia denied that its military was shelling the station.
Energodar reported that the city's power supply is carried out in the normal mode, Interfax reports. “Partly, in some areas, work is underway to turn on transformers, but this mainly concerns the industrial zone. The residential sector is fully lit, & mdash; said the head of the city administration Alexander Volga.
Zaporozhye nuclear power plant— Europe's largest nuclear power plant in terms of installed capacity and the third largest in the world. It is located on the banks of the Kakhovka reservoir on the Dnieper, not far from Energodar in the Zaporozhye region of Ukraine. The station consists of six VVER-1000 power units, the first of which was put into operation in December 1984, the sixth— in October 1995.
The Zaporozhye NPP accounts for six out of 15 operating nuclear power units in Ukraine. The plant annually generates 40–42 billion kW·h of electricity, which is almost 21% of Ukraine's electricity production and 50% of its production at nuclear power plants.
Zaporozhye NPP is connected to the united energy system of Ukraine by three power lines 750 kV and one 330 kV. It supplies electricity to Dnepropetrovsk, Zaporozhye, Nikolaev, Kherson and Odessa regions, and until November 2015— also to the Crimea (in 2015, a power line was blown up on the border with the Kherson region, through which energy was supplied to the peninsula). According to its own data, the nuclear power plant supplied electricity to 10 million people, as well as dozens of large industrial enterprises, including ArcelorMittal Kryvyi Rih; (former Kryvorizhstal), Zaporizhstal, Dneprospetsstal, as well as the Motor Sich aircraft building association. But some of them also receive electricity from the South Ukrainian NPP in the Mykolaiv region.
On September 10, Vladimir Rogov, a member of the main council of the pro-Russian military-civilian administration of the Zaporozhye region, announced that Ukraine had unilaterally stopped receiving energy from nuclear power plants. According to him, at that time, energy continued to be supplied to the Russian-controlled territories of the Zaporozhye and Kherson regions.
In early September, the station was visited by an IAEA delegation headed by the head of the agency, Rafael Grossi. According to the initial assessments of specialists, the NPP buildings were damaged as a result of shelling in several places.
Later, the agency published a report on the visit to the NPP. It said that the experts did not see signs of the spread of radiation, but the ongoing shelling poses a threat to nuclear safety. The agency called for the creation of a protected zone around the facility.
In early September, the fifth power unit was turned off at the nuclear power plant after shelling of the station's communication lines.
