Director General of the International Atomic Energy Agency (IAEA) Rafael Grossi said on October 31 that a small water leak was detected at one of the six reactors of the Zaporizhzhia NPP from the pulse line connected to the first circuit of the power unit. UNN reported this with reference to the IAEA press service.
Repairs are underway at Ukraine's Zaporizhzhya Nuclear Power Plant (ZNPP) at one of its six reactors after a small water leak was detected from a pulse line - essentially a small pipe connected to the unit's first circuit. The work is expected to be completed by the end of this week
A group of IAEA experts deployed at ZNPP reportedly visited Unit 1 on Tuesday after receiving information that one of the pulse lines that are part of the reactor's coolant pump support system had leaked and needed to be repaired. To carry out this work, it was necessary to reduce the pressure in the first circuit to atmospheric levels.
Currently, the welding work is supposedly complete and radiographic inspection of the welds is underway.
"The Agency will continue to closely monitor this issue, although we do not see any immediate nuclear safety concerns. In general, we have determined that regular maintenance of equipment, which is vital to ensure sustainable nuclear safety, is a challenge for Zaporizhzhia NPP during the conflict," said Director General Grossi.
Like almost every week, the team continued to hear explosions every day, although there were no reports of damage to the station.
Recall
On October 25 , Zaporizhzhia Nuclear Power Plant (ZNPP), which is under the control of the Russian occupiers, lost connection to the only 330 kilovolt (kV) backup power line for the second time in a month. The outage lasted more than a day.
