IAEA head Rafael Grossi acknowledged that the scenario in Ukraine's vitality system is the worst since September 2024, when substation monitoring started. Fixed instability within the energy grid undermines nuclear security, and the Zaporizhzhia Nuclear Energy Plant has misplaced exterior energy provide 12 instances.
The scenario within the vitality system is presently within the worst state since September 2024, when the Worldwide Atomic Power Company (IAEA) started monitoring substations vital to nuclear security and safety in Ukraine. This was acknowledged by the top of the company, Rafael Grossi, stories UNN.
The assaults on Ukraine's energy grid look like coordinated for optimum disruption, and their frequency and scale underscore that the general stability of the grid is deteriorating, not enhancing.
– Grossi mentioned.
He once more known as for optimum army restraint.
Nobody needs a nuclear accident and nobody advantages from it.
– mentioned the IAEA Director Basic.
He emphasised that the newest mission, carried out from December 1 to December 12, 2025, included visits to greater than ten substations – vital for making certain nuclear security by offering nuclear energy crops with the electrical energy wanted to chill the reactor and different security methods.
The mission's aim was to evaluate the injury, evaluation restore work, and determine sensible steps to reinforce the resilience of exterior energy sources for the nation's nuclear energy crops.
The IAEA Director Basic acknowledged that nuclear security on the three working nuclear energy crops within the territory managed by Ukraine stays beneath strain attributable to ongoing army actions and associated injury to vitality transmission infrastructure.
Over the previous weekend, energy grid outages brought on energy fluctuations and momentary disconnections of energy traces on the Khmelnytskyi, Rivne, and South Ukrainian NPPs, he famous. Based on him, in a number of instances, models operated at diminished energy to take care of grid stability and forestall gear injury.
The fixed instability in Ukraine's energy grid continues to undermine nuclear security. Though backup methods have functioned correctly, repeated losses of exterior energy and restricted redundancy enhance the chance and reinforce the necessity for dependable exterior energy provide.
– Grossi famous.
The IAEA staff additionally confirmed that steady and deliberate assaults on vital grid infrastructure have had a cumulative impression on NPP operations and personnel working circumstances. Energy outages have an effect on the cities the place station personnel stay, worsening residing circumstances and straight impacting personnel by disruptions to electrical energy, heating, and water provide.

As well as, it’s famous that the Russian-occupied Zaporizhzhia Nuclear Energy Plant (ZNPP) of Ukraine quickly misplaced exterior energy provide for the twelfth time for the reason that starting of the full-scale aggression early within the morning of December 13, as each the principle 750 kV Dniprovska energy transmission line and the backup 330 kV Ferroalloy-1 energy transmission line have been disconnected. All obtainable emergency diesel mills routinely began, making certain steady cooling and different necessary security features. Each exterior energy traces supplying the NPP – the most important in Europe – have since been reconnected, and the diesel mills have been returned to standby mode, the company clarified.

It additionally reported that on December 15, regardless of the ZNPP retaining entry to the 2 remaining exterior energy traces, one other incident highlighted the delicate nuclear security scenario on the plant. Energy transmission between the ZNPP switchyard and the Zaporizhzhia Thermal Energy Plant (ZTPP) switchyard by way of an autotransformer turned unavailable, considerably decreasing the pliability and resilience of the power's electrical configuration. Following an investigation carried out by the ZNPP, injury was discovered to the facility line between the autotransformer and the ZTPP switchyard, which was reportedly brought on by army exercise.
The ZNPP knowledgeable the IAEA staff on the plant that entry to the affected space couldn’t be granted for security causes. As of right now, the ZNPP continues to be exploring methods to restore the road.
