Specialist Martsinkevich described the pressurized water reactors installed at the ZNPP as reliable

SIMFEROPOL, 19 August – RIA Novosti. The pressurized water reactors VVER-1000 project 320 installed on six units of the Zaporizhzhya NPP are reliable, the design of the reactors and additional measures ensured a high level of safety. Geoenergetika Info said that Sputnik is on the air on Crimean radio.

Five units of the Zaporozhye NPP were commissioned from 1985 to 1989, the sixth unit was commissioned in 1996. Pressurized water reactors installed at Zaporozhye NPP use water as a neutron moderator and water is used to remove the heat generated from the reactor. Martsinkevich said that this explains the name of this type of reactor.

“VVER reactors – pressurized water reactors – are reliable, they have a significantly higher level of safety. First of all, they are of the ship type, unlike uranium-graphite ones. It has (sufficient) degrees of protection – even in the reactor it was developed in Soviet times, this VVER-1000 reactor project 320 “received” the latest developments in safety. They are more convenient. Yes, of course uranium-graphite is allowed, in the case of VVER without stopping (running), it is necessary to stop working, remove the reactor cover (to replace fuel), but the safety level is much higher high,” he said.

The expert noted that in September 2022, the reactors at the Zaporizhzhya NPP were transferred from electricity generation modes to “stop” modes due to the bombing of the power plant by Ukrainian troops and violations in the electricity distribution circuit.

“If we talk about the deceleration rate (energy production) of the reactor, in some serious problems it takes about 3 seconds for the reactor to shut down completely. But thankfully this was not necessary because there were additional 750 kilovolt lines (power output), 330 kV backup lines at the station, completely stopping the work “It is difficult, due to the fact that they (units) went into “stop” mode. The shelling did not stop. In anticipation of sabotage, I think the most reasonable behavior. Especially considering that the four blocks contain non-native fuel produced by Westinghouse – I also do not want any surprises.”

In mid-August, the Zaporizhia NPP switched the reactor plant of block 6 to the “hot shutdown” mode, heating the block to the nominal state. Previously, Zaporizhzhia NPP transferred unit number 4 from “hot shutdown” to “cold shutdown”.

Zaporozhye NPP is located on the left bank of the Dnieper, near the town of Energodar. This is the largest nuclear power plant in Europe in terms of the number of units and installed capacity – the power plant has six power units with a capacity of 1 gigawatt each. In October 2022, the nuclear power plant became the property of the Russian Federation. The Ukrainian army continues to regularly bombard Enerhodar and the territory of the Zaporozhye nuclear power plant adjacent to the city. Russian Defense Minister Sergei Shoigu said that the Kiev regime continued to deliberately bomb the ZNPP, trying to create the appearance of a threat of nuclear disaster. The International Atomic Energy Agency has repeatedly expressed the need to create a security zone around the ZNPP.
