Ukraine war keeps nuclear safety on a knife-edge, UN watchdog warns

Russian forces have been carrying out strikes on critical infrastructure amid freezing winter temperatures as their full-scale invasion approaches the four-year mark next month. 

IAEA Director-General Rafael Grossi said the electrical grid was again the target of military activity this past weekend, leading to significant impacts to several regions and nuclear power plant operations. 

Power lines down 

The fighting caused power lines linking Ukraine with neighbouring countries to be disconnected, which in turn knocked out supplies inside Ukraine.  

As a result, a unit at one nuclear power plant disconnected from the grid due to fluctuations and automatically shut down, while other units at other plants were forced to reduce power. 

The Chornobyl site – where the world’s worst nuclear disaster occurred in 1986 – experienced a complete loss of offsite power and relied on its emergency diesel generators for roughly an hour. 

‘Ever-present risks’ 

“This latest grid event in Ukraine is a stark reminder of the ever-present risks to nuclear safety and security arising from deteriorating grid conditions,” said Mr. Grossi. 

He stressed that extensive repairs are needed to improve the reliability of power supply to nuclear power plants and strengthen their resilience. 

“Once again, I call for maximum military restraint, as well as full observance of the Seven Indispensable Pillars to enable these essential repairs to take place.” 

Seven safety principles 

The IAEA developed the seven pillars for nuclear safety in Ukraine in March 2022, just weeks after the war began – the first time ever that armed conflict has occurred amid the facilities of a major nuclear power programme. 

Measures include maintaining the physical integrity of facilities, ensuring offsite power supply from the energy grid, and implementing effective radiation monitoring systems. 

Operating staff must also be able to fulfill their safety and security duties and to make decisions without any undue pressure. 

Vital inspections 

As military activity increases impacting the electricity grid in Ukraine, three IAEA teams are conducting a two-week mission visiting 10 substations critical to nuclear safety and security.  

The objective is to assess the continuing damage to the grid, review repair efforts and identify practical steps to strengthen the resilience of off-site power supplies to nuclear power plants.  

This marks the second IAEA mission in as many months.  A mission this past December confirmed the effects of cumulative impacts on nuclear power plant operations and staff conditions.

Syria: Political transition on ‘a knife-edge’ amid military skirmishes

Geir Pedersen told ambassadors that in Sweida governate, where sectarian violence in July also spurred conflict in the capital Damascus, the 19 July ceasefire has come under strain, but the conflict has not resumed so far.

However, “we are still seeing dangerous hostilities and skirmishes on the margins of Sweida, and violence could resume at any moment,” he said.

In northeast Syria, efforts to implement the 10 March agreement between the interim security forces and the mostly-Kurdish Syrian Democratic Forces (SDF) continue. Just this month, there have been spikes in violence between the two militaries in the Aleppo governorate.

While attempts to convene the two sides outside of the country have been unsuccessful, Mr. Pedersen welcomed reports of contacts between officials.

Despite these security incidents, Mr. Pedersen stressed that the situation has been relatively calm this month, applauding the efforts of those who have worked to tamp down hostilities.

However, in terms of the political situation, “the country remains deeply fragile and the transition remains on a knife-edge.

Political transition?

After 13 years of civil war, Mr. Pedersen underscored the need for an inclusive, Syrian-led political transition that enables the Syrian people determine their own future peacefully, independently and democratically.

Syrians need to feel that this transition is not a series of ad hoc arrangements and isolated institutions, but a clear and comprehensive path, based on inclusion and transparency, to implement the principles of resolution 2254,” he said.

To encourage the voluntary, safe return of refugees and internally displaced persons, Mr. Pedersen stressed the need for coordinated support to repair Syria’s depleted infrastructure.

The best way to secure such support is through a genuine political transition that lays the path for long-term stability and sustainable governance. Indeed, without credible reforms, stronger institutions, and a firm commitment to the rule of law, international support risks being squandered or misdirected,” he stressed.

Humanitarian situation still dire

Amid the precarious military and political situation, 16 million Syrians across the country need humanitarian aid, according to Emergency Relief Coordinator Tom Fletcher.

Additionally, over 185,000 people have been displaced across Sweida, Dar’a, Rural Damascus and beyond.

The overall situation is dire. We need to sustain urgent delivery of food, health, shelter, clean water, fuel, restoration of water and electricity infrastructure, education. In some areas, those arriving now outnumber the existing population. Services are overwhelmed,” said Mr. Fletcher.

Teams from the UN humanitarian aid coordination office (OCHA) have visited Sweida and other towns, delivering aid and assessing needs.

OCHA has also provided emergency food packages, flour and essential household items to tens of thousands of people.

However, insecurity and road closures have disrupted the supply of aid from the UN, NGO partners and the Syrian Arab Red Crescent.

“We need better humanitarian and commercial access. And most of all, we need safety,” Mr. Fletcher stressed, particularly referring to attacks on aid convoys, health facilities, medics and ambulances.

Drastic cuts

Nevertheless, “despite funding and security challenges, the UN and partners are delivering as much lifesaving support as we can with the resources we have,” reaching 3.5 million people on average each month, a noticeable increase from last year.

But with the 2025 humanitarian appeal in the country only 14 per cent funded, ongoing aid cuts in many Western capitals are projected to lead to reduced staffing of at least 40 per cent across the humanitarian community inside Syria.

The UN relief chief emphasised that without more funding, “we won’t be able to sustain these vital efforts, let alone expand them to more people who need them.”

Furthermore, while he urged humanitarian support, he also stressed that long-term development investment is needed in Syria “to reduce and ultimately end reliance on humanitarian aid.”
