Ukraine’s Zaporizhia NPP (ZNPP) suffered a complete loss of external power for 11 hours recently, International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi said in his latest update. This forced the plant to rely on emergency diesel generators for reactor cooling and other essential nuclear safety and security functions. ZNPP lost all off-site electricity at the site when its last remaining 750 kilovolt (kV) line was disconnected following reports of missile strikes across Ukraine. This was the sixth time the plant has been running on emergency diesel generators during the ongoing military conflict, he told the IAEA Board of Governors.

Both the stations, in the north of England, have been operating since the 1980s. EDF announced in September 2022 it was reviewing the case for a short extension.
The two stations were originally due to end generation in 2014. EDF Energy said it invested significant resources to enable the forecast to move to 2024. This has now been moved by a further two years to March 2026.
Heysham A and Hartlepool A both have two advanced gas-cooled reactor units. According to the Intrnational Atomic Energy Agency they all began full commercial operation in 1989, although the IAEA says they were first connected to the grid in either 1983 or 1984.
According to International Atomic Energy Agency data, the net capacity of all four units combined in 2,245 MW.

The incident led the agency’s director-general Rafael Grossi to tell its board of governors today that he was “astonished” by the complacency. “What are we doing to prevent this happening? We are the IAEA, we are meant to care about nuclear safety,” Grossi said.
The six-unit station’s only remaining back up 330 kilovolt line had already been damaged a few days ago and is under repair.
As a result, all 20 of the site’s emergency diesels generators were activated. The site’s essential power is now being provided by eight of those diesels with the rest now in standby mode. Grossi said there is enough diesel on site for 15 days of operation
The two out of six units that were in hot shutdown are moving to cold shutdown. When a reactor is in cold shutdown, the fuel and control rods can be safely removed and exchanged, and maintenance can be performed. However, once a reactor has gone into a cold shutdown, it requires more time and energy to restart the reaction than if it had been hot.

External power has been restored to Europe's largest nuclear power plant, Zaporizhzhia. The loss of external power, which meant 10 hours spent relying on emergency diesel generators for essential safety functions, followed missile strikes on Ukraine. The International Atomic Energy Agency's (IAEA's) director general warned that action is needed or "one day our luck will run out".

A senior Russian diplomat says that talks on a security zone around the Zaporizhzhia nuclear power plant "are losing momentum" while Ukraine's energy minister says that diplomatic steps to return it to Ukraine have "reached a dead end".

A long-delayed rotation of International Atomic Energy Agency (IAEA) at the Zaporizhia NPP (ZNPP) has finally taken place on the fourth attempt. IAEA Director General Rafael Mariano Grossi said the delay had complicated efforts to support nuclear safety and security during the military conflict in Ukraine.

The International Atomic Energy Agency (IAEA) has issued a report on Nuclear Safety, Security & Safeguards in Ukraine, covering the period between February 2022 and February 2023. The 52-page report provides an overview of the situation and the IAEA’s activities to reduce the likelihood of a nuclear accident during the armed conflict.

Petro Kotin told the My-Ukraina (“We are Ukraine”) news channel that Russia’s shelling of the station and the area around it since the invasion began in February 2022 is “an act of nuclear terrorism”.
He said Zaporizhzhia – which has six Soviet era reactors and is the largest commercial nuclear facility in Europe – had operated safely for almost 40 years, but since Russia took control “we have had 20 very serious events, including those on the [International Atomic Energy Agency’s] emergency scale”.
Kotin said Russia had seized the nuclear station and all the infrastructure used to detect and respond to possible nuclear radiation incidents.
“They are all seized, all this infrastructure is broken,” he said. Kotin added that staff are being pressured to sign a contract to work for Russia’s Rosenergoatom, the nuclear plant operations subsidiary of Atomenergoprom, itself a subsidiary of state-owned nuclear corporation Rosatom.

International Atomic Energy Agency (IAEA) Director General Rafael Mariano Grossi has appealed for constructive efforts by all involved parties to facilitate this month’s already delayed rotation of experts to and from Ukraine’s Zaporizhia NPP (ZNPP). Grossi stressed the vital importance of the continued presence of the IAEA Support & Assistance Mission to Zaporizhia (ISAMZ) at Europe’s largest NPP.
