The last operating reactor at the Zaporizh* nuclear power plant in southern Ukraine has been completely shut down and disconnected from the grid, the Ukrainian operator Ener*oatom said on Sunday.

"Arrangements for its cooling and transfer to a cold state are underway," Energoatom said, adding that in recent days the sixth -- and last operating -- reactor at the plant had been powering exclusively the facility's in-house needs because "all transmission lines linking the Zaporizhzhya NPP to the Ukrainian power system were damaged due to Russian shelling."

"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," Energoatom said.

On September 11, at 03:41, power unit No. 6 of the ZNPP was disconnected from the power grid. Preparations are underway for its cooling and transfer to a cold state.

Details: The agency explains that for the past three days, the 6th power unit has been operating in island mode, feeding only its own needs of the ZNPP at a critically low power level, as all communication [?] lines of the Zaporizh* NPP with the Ukrainian power system were damaged due to Russian shelling.

Literally: "On the evening of September 10, after one of these communication lines was restored to its operational capacity, power supply for ZNPP's own needs became possible from the energy system of Ukraine....

Prehistory:
• On September 1, the mission of the International Atomic Energy Agency  arrived at the Zaporizh* NPP  in occupied Ener*odar. On September 5, four of the six participants of the IAEA mission completed their work at the station, while  two representatives of the organization were supposed to[!] remain there . ...

Zaporozhye NPP was switched to power from diesel generators, said the chairman of the movement "We are with Russia", a member of the main council of the military-civilian administration of the Zaporozh* region Vladimir Rogov.

"Now, in order to maintain technological processes, the power supply of the Zaporizh* NPP has been switched to diesel generators. This is a temporary solution," the politician told RIA Novosti.

According to him, this is due to the fact that "the K*v authorities deliberately fired on and disabled the power lines that feed the nuclear power plant, and also did not accept the energy generated at the nuclear power plant, artificially [?] blocking the flow to the right bank of the Dnieper."...

The sixth reactor "was stopped at 3:45 am. Now it doesn't generate electricity," Vladimir Rogov, a member of the Zaporozh* Region administration, told RIA-Novosti.

Ukrainian state-owned company Ener*oatom has also confirmed the so-called `cold shutdown' of the last unit, with the Zaporozh* facility coming to a complete halt. The largest nuclear power plant in Europe has been controlled by Russian forces since March, but is still operated by Ukrainian staff. Despite the shutdown of the Zaporozh* nuclear power plant, energy supply to the nearby town of Ener*odar is continuing as usual, the local authorities assured.
