Cameco's stock prices have dropped significantly since the announcement of the company's Cigar Lake Mine flooding and recent shutdown of the Port Hope facility's uranium hexafluoride (UF6) conversion plant, despite the uranium giant announcing its most profitable quarter ever, with $205 million in earnings on $725 million in revenues.

Share prices were at $52.15 on July 12 and, as of August 7, had hit a low of $40.37 on the Toronto Stock Exchange.

Another possible contributing factor to the stock's decline is the discovery of uranium contamination and subsequent shutdown of the Port Hope plant. The uranium and potassium was found under the plant's cooling tank July 13 and announced to the press and the public July 20.

But a possible alternative explanation behind the UF6 plant's shutdown has been advanced by local citizen Pat McNamara, a self-described "watchdog" who ran unsuccessfully for mayor in last November's municipal elections.

Mr. McNamara wrote in an e-mail to this newspaper he was contacted by "a senior Cameco employee" last year and told "the building is in danger of imminent collapse."

Mr. McNamara stated the unidentified employee "could not" go public with his concerns, "as it would have meant the end of his career in the nuclear industry."

Mr. McNamara theorized the recent revelation about contamination and need for remediation was being used as a "ruse to hide structural problems."

But United Steelworkers Local 13173 President Chris Leavitt said Mr. McNamara's comments are a "pile of hogwash" and that he "would walk into that building without a worry at any time.

"This is way over the top," Mr. Leavitt said during a phone interview.

"If the building was in imminent danger of collapsing, we couldn't hide that. I feel just as safe today as ever."

In 2005, the Canadian Nuclear Safety Commission (CNSC) hired Cyril Hare consultants to do an Emergency Response Evaluation of the facility.

According to Mr. McNamara, the report stated: "The site includes approximately 44 structures or activity areas. The structures that have been constructed since the 1960s should have been designed and constructed in compliance with one of the editions of the National Building Code. None of the structures were constructed in compliance with the edition of the National Building Code that was in effect at the time of the design and construction of the buildings."

However, "there was no evidence of specific violations provided by the consultant to substantiate the statement," said Sunni Locatelli, director of the CNSC's communications programs division, after confirming the quote in the report regarding the National Building Code.

"The consultant's findings resulted in recommendations for improvements to fire safety systems. Cameco responded to these recommendations to the satisfaction of the CNSC."

The Evening Guide forwarded Mr. McNamara's allegations to Doug Prendergast, spokesperson for Cameco, and he replied via e-mail, saying, "Cameco is not aware of any problems with the structural integrity of building 50."

He has not yet responded to a question on whether Golder Associates, the geo-technical consulting firm hired to explore the level of soil contamination at the UF6 plant, is also looking at the building's structural integrity.

Nor did he confirm whether equipment had to be moved from the upper floors, as suggested by Mr. McNamara.

"With regard to the recent contamination of the Port Hope Cameco site, CNSC staff visited the site on July 19 and July 26, met with Cameco staff and inspected the affected area of the plant," said Aurele Gervais, spokesperson for the CNSC. "Cameco is providing updates to CNSC staff daily on progress in investigating this issue. There is a weekly conference call between Cameco and CNSC staff."

Mr. Gervais said CNSC staff would do another inspection and "will continue with regular inspections until the (contamination) issue is fully understood."

Mr. Gervais added ongoing groundwater monitoring around the UF6 plant indicates the current situation does not pose a risk to public health or the environment; he said CNSC staff continues to monitor the situation to ensure it remains contained and is satisfied with the actions taken by Cameco to further investigate the matter.

"CNSC staff will present an update on this issue to the commission in September," said Mr. Gervais. "With regard to structural integrity, the UF6 facility was built to the appropriate codes in the early 1980s. The licensee is responsible to ensure that the facility continues to be maintained in a safe state and CNSC staff verifies this through our compliance program. The topic of adherence to the National Building Code of Canada and the National Fire Code of Canada was discussed extensively at the re-licensing hearing in the fall of 2006."

According to the approved licence application from March 1, 2007 to February 29, 2012, the CNSC is satisfied Cameco meets all of the requirements to carry on operations in a safe manner.

Allegations that "insider trading" was responsible for the seven-day delay from the time the uranium leak was found to its public reporting have been deemed false, according to Gord Struthers of Cameco's head office in Saskatoon, Sask. Although he admitted Cameco employees do have stock options as part of their benefits program, there are certain times when employees are in a "blackout" situation and not allowed to trade their shares.

"At the time of this development, there was a planned blackout because of the quarterly report about to be released," said Mr. Struthers. "There is no possibility that the executive or the employees could have traded shares."

At this time, Cameco has yet to determine the impacts the minimum two-month plant closure will have on its earnings forecasts as presented in July.

"Our forecasted profits are still being assessed," said Mr. Prendergast.

New Mexico Could Reap $30 Billion Driving on Electricity

New Mexico EV Benefits highlight cheaper fuel, lower maintenance, cleaner air, and smarter charging, cutting utility bills, reducing NOx and carbon emissions, and leveraging incentives and renewable energy to accelerate EV adoption statewide.

 

Key Points

New Mexico EV Benefits are the cost, grid, and emissions gains from EV adoption and optimized off-peak charging.

✅ Electricity near $1.11 per gallon equivalent cuts fueling costs

✅ Fewer moving parts mean less maintenance and lifecycle costs

✅ Off-peak charging reduces utility bills and grid emissions

 

What would happen if New Mexicans ditched gasoline and started to drive on cleaner, cheaper electricity? A new report from MJ Bradley & Associates, commissioned by NRDC and Southwest Energy Efficiency Project, answers that question, demonstrating that New Mexico could realize $30 billion in avoided expenditures on gasoline and maintenance, reduced utility bills, and environmental benefits by 2050. The state is currently considering legislation to jump-start that transition by providing consumers incentives to support electric vehicle (EV) purchases and the installation of charging stations, drawing on examples like Nevada's clean-vehicle push to accelerate deployment, a policy that would require a few million dollars in lost tax revenue. The report shows an investment of this kind could yield tens of billions of dollars in net benefits.


$20 Billion in Driver Savings

EVs save families money because driving on electricity in New Mexico is the cost-equivalent of driving on $1.11 per gallon gasoline. Furthermore, EVs have fewer moving parts and less required maintenance—no oil changes, no transmissions, no mufflers, no timing belts, etc. That means that tackling the nation’s largest source of carbon pollution, transportation, could save New Mexicans over $20 billion by 2050 because EVs are cheaper to charge and maintain than gas powered cars, and an EV boom benefits all customers through lower rates.

Those are savings New Mexico can bank on because the price of electricity is significantly cheaper than the price of gasoline and also inherently more stable. Electricity is made from a diverse supply of domestic and increasingly clean resources, and 2021 electricity lessons continue to inform grid planning today. Unlike the volatile world oil market, New Mexico’s electric sector is regulated by the state’s utility commission. Adjusted for inflation, the price of electricity has been steady around the dollar-a-gallon equivalent mark in New Mexico for the last 20 years, while gas prices jump up or down radically and unpredictably.

$4.8 Billion in Reduced Electric Bills

While some warn that electric cars will challenge state power grids, New Mexico can charge millions of EVs without the need to make significant investments in the electric grid. This is because EVs can be charged when the grid is underutilized and renewable energy is abundant, like when people are sleeping overnight when wind energy generation often peaks. And the billions of dollars in new utility revenue from EV charging in excess of associated costs will be automatically returned to utility customers per an accounting mechanism that is already in state law that requires downward adjustment of rates when sales increase. Accordingly, widespread EV adoption could reduce every utility customer’s electric bill.

Thankfully, New Mexico’s electric industry is already acting to ensure utility customers in the state realize those benefits sooner rather than later. The state’s rural electric cooperatives have proposed an ambitious plan to leverage funds available as a result of the Volkswagen diesel scandal to build a state-wide public fast charging network that mirrors progress as Arizona goes EV across the Southwest. Additionally, New Mexico’s investor-owned utilities will soon propose transportation electrification investments as required by legislation NRDC supported last year that Governor Lujan Grisham signed into law.

$4.8 Billion in Societal Benefits from Reduced Pollution

The report estimates that widespread EV adoption would dramatically reduce emissions of greenhouse gases from passenger vehicles in New Mexico, and also cut emissions of NOx, a local pollutant that threatens the health off all New Mexicans, especially children and people with respiratory conditions. The report finds growing the state’s EV market to meet New Mexico’s long-term environmental goals would yield $4.8 billion in societal benefits.

The Bottom Line: New Mexico Should Act Now to Accelerate its EV Market

Adding it all up, that’s more than $30 billion in potential benefits to New Mexico by 2050. Here’s the catch: as of June 2019, there were only 2,500 EVs registered in New Mexico, which means the state needs to accelerate the EV market, as the American EV boom ramps up nationally, to capture those billions of dollars in potential benefits. Thankfully, with second generation, longer range, affordable EVs now available, the market is well positioned to expand rapidly as the state moves to adopt Clean Car Standards that will ensure EVs are available for purchase in the state.

Getting it right

New Mexico has enormous amounts to gain from a small investment in incentives that support EV adoption now. For that investment to pay off, it needs to send a clear and unambiguous signal. Unfortunately, the same legislation that would establish tax credits to increase consumer access to electric vehicles in New Mexico was recently amended so it would not be helpful for 80 percent of consumers who lease, instead of buying EVs. And it would penalize EV drivers at the same time—with a $100 annual increase in registration fees, even as Texas adds a $200 EV fee under a similar rationale, to make up for lost gas tax revenue. That’s significantly more than what drivers of new gasoline vehicles pay annually in gas taxes in the state. Consumer Reports recently analyzed the growing trend to unfairly penalize electric cars via disproportionately high registration fees. In doing so, it estimated that the “maximum justifiable fee” to replace gas tax revenue in New Mexico would be $53. Anything higher will only slow or stop benefits New Mexico can attain from moving to cleaner cars.

To be clear, everyone should pay their fair share to maintain the transportation system, but EVs are not the problem when it comes to lost gas tax revenue. We need a comprehensive solution that addresses the real sources of transportation revenue loss while not undermining efforts to reduce dependence on gasoline. Thankfully, that can be done.

Gas-electric hybrid vehicles get a boost in the US from Ford, others

U.S. Hybrid Vehicle Sales Outlook highlights rising hybrid demand as an EV bridge, driven by emissions rules, range anxiety, charging infrastructure gaps, and automaker strategies from Ford, Toyota, and Stellantis across U.S. markets.

 

Key Points

Forecast of U.S. hybrid sales shaped by EV adoption, emissions rules, charging access, and automaker strategies.

✅ S&P sees hybrids at 24% of U.S. sales by 2028

✅ Bridges ICE to EV amid range and charging concerns

✅ Ford, Toyota, Stellantis expand U.S. hybrid lineups

 

Hybrid gasoline-electric vehicles may not be dying as fast as some predicted in the auto sector’s rush to develop all-electric models.

Ford Motor is the latest of several top automakers, including Toyota and Stellantis, planning to build and sell hundreds of thousands of hybrid vehicles in the U.S. over the next five years, industry forecasters told Reuters.

The companies are pitching hybrids as an alternative for retail and commercial customers who are seeking more sustainable transportation, but may not be ready to make the leap to a full electric vehicle.

"Hybrids really serve a lot of America," said Tim Ghriskey, senior portfolio strategist at New York-based investment manager Ingalls & Snyder. "Hybrid is a great alternative to a pure electric vehicle (and) it's an easier sell to a lot of customers."

Interest in hybrids is rebounding as consumer demand for pure electrics has not accelerated as quickly as expected, with EV market share dipping in Q1 2024 according to some analyses. Surveys cite a variety of reasons for tepid EV demand, from high initial cost and concerns about range to lengthy charging times and a shortage of public charging infrastructure in many regions.

“With the tightening of emissions requirements, hybrids provide a cleaner fleet without requiring buyers to take the leap into pure electrics,” said Sam Fiorani, vice president at AutoForecast Solutions.

S&P Global Mobility estimates hybrids will more than triple over the next five years, accounting for 24% of U.S. new vehicle sales in 2028. Sales of pure electrics will claim about 37%, supported by strong U.S. EV sales into 2024 momentum, leaving combustion vehicles — including so-called “mild” hybrids — with a nearly 40% share.

S&P estimates hybrids will account for just 7% of U.S. sales this year, and pure electrics 9%, underscoring that EV sales still lag gas cars as internal combustion engine (ICE) vehicles take more than 80%.

Historically, hybrids have accounted for less than 10% of total U.S. sales, with Toyota’s long-running Prius among the most popular models. The Japanese automaker has consistently said hybrids will play a key role in the company's long-range electrification plans as it slowly ramps up investment in pure EVs.

Ford is the latest to roll out more aggressive hybrid plans. On its second-quarter earnings call in late July, Chief Executive Jim Farley surprised analysts, saying Ford expects to quadruple its hybrid sales over the next five years after earlier promising an aggressive push into all-electric vehicles.

“This transition to EVs will be dynamic,” Farley told analysts. “We expect the EV market to remain volatile until the winners and losers shake out.”

Among Ford’s competitors, General Motors appears to have little interest in hybrids in the U.S., while Stellantis will follow Toyota and Ford’s hedge by offering U.S. buyers a choice of different powertrains, including hybrids, until sales of pure electric vehicles start to take off after mid-decade, a potential EV inflection point according to forecaster GlobalData.

In a statement, GM said it, echoing leadership's view that EVs won't go mainstream until key issues are addressed, "continues to be committed to its all-electric future ... While we will have hybrid vehicles in our global fleet, our focus remains on transitioning our portfolio to electric by 2030.”

Stellantis said hybrids now account for 36% of Jeep Wrangler sales and 19% of Chrysler Pacifica sales. In addition to new pure electric models coming soon, "we are very bullish on hybrids going forward," a spokesperson said.

This year, manufacturers are marketing more than 60 hybrids in the U.S. Toyota and its premium Lexus brand are selling at least 18 different hybrid models, enabling the Japanese automaker to maintain its stranglehold on the sector.

Hyundai and sister brand Kia offer seven hybrid models, with Ford and Lincoln six. Stellantis offers just three, and GM’s sole entry, due out later this year, is a hybrid version of the Chevrolet Corvette sports car.

But hybrids remain in short supply at many U.S. dealerships.

Andrew DiFeo, dealer principal at Hyundai of St. Augustine, south of Jacksonville, FL, doesn't see EV adoption hitting the levels the Biden administration wants until EV charging networks are as ubiquitous as gas stations.

"Hybrids are a great bridge to whatever the future holds,” said DiFeo, adding, “I've got zero in stock (and) I've got customers that want all of them."

UK Anticipates a 16% Decrease in Energy Bills in April

UK Energy Price Cap Cut 2024 signals relief as wholesale gas prices fall; Ofgem price cap drops per Cornwall Insight, aided by LNG supply, mild winter, despite Red Sea tensions and Ukraine conflict impacts.

 

Key Points

A forecast cut to Great Britain's Ofgem price cap as wholesale gas falls, easing typical annual household bills in 2024.

✅ Cap falls from £1,928 to £1,620 in April 2024

✅ Forecast £1,497 in July, then about £1,541 from October

✅ Drivers: lower wholesale gas, LNG supply, mild winter

 

Households in Great Britain are set to experience a significant reduction in energy costs this spring, with bills projected to drop by over £300 annually. This decrease is primarily due to a decline in wholesale gas prices, offering some respite to those grappling with the cost of living crisis.

Cornwall Insight, a well-regarded industry analyst, predicts a 16% reduction in average bills from the previous quarter, potentially reaching the lowest levels since the onset of the Ukraine conflict.

The industry’s price cap, indicative of the average annual bill for a typical household, is expected to decrease from the current £1,928, set earlier this month, to £1,620 in April – a reduction of £308 and £40 less than previously forecasted in December, as ministers consider ending the gas-electricity price link to improve market resilience.

Concerns about escalating tensions in the Red Sea, where Houthi rebels have disrupted global shipping, initially led analysts to fear an increase in wholesale oil prices and subsequent impact on household energy costs.

Contrary to these concerns, oil prices have remained relatively stable, and European gas reserves have been higher than anticipated during a mild winter, with European gas prices returning to pre-Ukraine war levels since November.

Cornwall Insight anticipates that energy prices will continue to be comparatively low through 2024. They predict a further decline to £1,497 for a typical annual bill from July, followed by a slight increase to £1,541 starting in October.

This forecast is a welcome development for Britons who have been dealing with increased expenses across various sectors, from food to utilities, amidst persistently high inflation rates, with energy-driven EU inflation hitting lower-income households hardest across member states.

Energy bills saw a steep rise in 2021, which escalated further due to the Ukraine conflict in 2022, driving up wholesale gas prices. This surge prompted government intervention to subsidize bills, with the UK price cap estimated to cost around £89bn to the public purse, capping costs to a typical household at £2,500.

Cornwall Insight noted that the supply of liquified natural gas to Europe had not been as adversely affected by the Red Sea disruptions as initially feared. Moreover, the UK has been well-supplied with gas from the US, which has become a more significant supplier since the Ukraine war, even as US electricity prices have risen to multi-decade highs. Contributing factors also include lower gas prices in Asia, mild weather, and robust gas availability.

Craig Lowrey, a principal consultant at Cornwall Insight, remarked that concerns about Red Sea events driving up energy prices have not materialized, allowing households to expect a reduction in prices.

On Monday, the next-month wholesale gas price dropped by 4% to 65p a therm.

However, Lowrey cautioned that a complete return to pre-crisis energy bill levels remains unlikely due to ongoing market impacts from shifting away from Russian energy sources and persistent geopolitical tensions, as well as policy changes such as Britain’s Energy Security Bill shaping market reforms.

Richard Neudegg, director of regulation at Uswitch, welcomed the potential further reduction of the price cap in April. However, he pointed out that this offers little solace to households currently struggling with high winter energy costs during the winter. Neudegg urged Ofgem, the energy regulator, to prompt suppliers to reintroduce more competitive and affordable fixed-price deals.

ERCOT Issues RFP to Procure Capacity to Alleviate Winter Concerns

ERCOT Winter Capacity RFP seeks up to 3,000 MW through generation and demand response to bolster Texas grid reliability during peak load, leveraging Reliability Must-Run, incentive factors, and EEA risk mitigation for the 2023-24 season.

 

Key Points

An ERCOT initiative to procure 3,000 MW of generation and demand response to reduce EEA risk and improve reliability.

✅ Targets 3,000 MW from generation and demand response

✅ Uses RMR-style contracts with flexible incentive factors

✅ Aims to lower EEA probability below 10% this winter

 

The Electric Reliability Council of Texas (ERCOT) issued a request for proposals to stakeholders to procure up to 3,000 MW of generation or demand response capacity to meet load and reserve requirements during the winter 2023-24 peak load season (Dec. 1, 2023, through Feb. 29, 2024), amid ongoing Texas power grid challenges across the region.

ERCOT cited “several factors, including significant peak load growth since last winter, recent and proposed retirements of dispatchable Generation Resources, and recent extreme winter weather events, including Winter Storm Elliott in December 2022, Winter Storm Uri in February 2021, and the 2018 and 2011 winter storms, each of which resulted in abnormally high demand during winter weather.” It now seeks additional capacity under its “authority to prevent an anticipated Emergency Condition,” reflecting nationwide blackout risks identified by grid experts.

In its notice regarding the RFP, ERCOT identified a number of mothballed and recently decommissioned generation resources that may be eligible to offer capacity under the RFP. It further stated that offers must comport with the format of its “Reliability Must-Run” agreement but could include a proposed “Incentive Factor” that reflects the revenues the unit owners determine would be necessary to bring the unit back to operation. It added that the Incentive Factor is not necessarily limited to 10%. Providers of eligible demand response can submit offers based on similar principles that are not necessarily constrained by cost. The notice identifies potential acceptable sources of demand response, describes certain parameters for the kinds of demand response that are permitted to respond to the RFP, and outlines the time periods during which ERCOT must be able to deploy the demand response resources to improve electricity reliability across the system.

To meet the Dec. 1, 2023, service start date, ERCOT developed an aggressive timeline to solicit and evaluate proposals through the RFP. Responses to the RFP are due Nov. 6, 2023. ERCOT’s schedule provides that it will notify market participants that obtain awards on Nov. 23, 2023. Expect contracts to be executed by Nov. 30, 2023.

Unlike Regional Transmission Organizations in the Northeastern United States, ERCOT does not have a capacity market. Instead, ERCOT relies on a high price cap of $5,000 per MWh for its energy market (decreased from the $9,000 per MWh cap in effect during Winter Storm Uri) and an Operating Reserve Demand Curve adder that pays additional funds to generators supplying power and ancillary services, an area recently scrutinized for improper payments when supply conditions are tight. In the wake of Winter Storm Uri, some calls were made to have ERCOT adopt a capacity market for reliability reasons, and a number of legal battles continue to play out in the wake of Winter Storm Uri. (See recent McGuireWoods legal alert “Winter Storm Uri Power Dispute Reaches the Supreme Court of Texas.”) Though a capacity market was not adopted, the Texas Legislature approved a $7.2 billion loan program, widely described as an electricity market bailout for generators, to build up to 10,000 MW of dispatchable generation. The legislature also approved a version of the Public Utility Commission of Texas’ proposal to establish a “Performance Credit Mechanism,” but with a cost cap of $1 billion.

The loss of life and economic impacts of Winter Storm Uri in 2021, along with the energy crunches and calls for conservation this past summer, are driving changes to ERCOT’s “energy-only” market, including electricity market reforms under consideration. Texas policymakers are providing multiple financial incentives to promote investment in dispatchable on-demand generation, and voters will consider funding to modernize generation measures this year to make the Texas grid more reliable and able to deal with power demand from a growing economy and increased demand for electricity driven by weather. In the meantime, ERCOT’s plan to procure 3,000 MW through this RFP process is a stopgap measure intended to bolster reliability for the upcoming winter season and lower the probability of load shed in the event of severe winter weather.

Ameren, Safe Electricity urge safety near downed lines

Downed Power Line Vehicle Safety: Follow stay-in-the-car protocol, call 911, avoid live wires and utility poles, and use the bunny hop to escape only for fire. Electrical hazards demand emergency response caution.

 

Key Points

Stay in the car, call 911, and use a bunny hop escape only if fire threatens during downed power line incidents.

✅ Stay in vehicle; tell bystanders to keep back and call 911.

✅ Exit only for fire; jump clear and bunny hop away.

✅ Treat all downed lines as live; avoid paths to ground.

 

Ameren Illinois and Safe Electricity are urging the public to stay in their cars and call 911 in the event of an accident involving a power pole that brings down power lines on or around the car.

In a media simulation Tuesday at the Ameren facility on West Lafayette Avenue, Ameren Illinois employees demonstrated the proper way to react if a power line has fallen on or around a vehicle, as some utilities consider on-site staffing measures during outbreaks. Although the situation might seem rare, Illinois motorists alone hit 3,000 power poles each year, said Krista Lisser, communications director for Safe Energy.

“We want to get the word out that, if you hit a utility pole and a live wire falls on your vehicle, stay in your car,” Lisser said. “Our first reaction is we panic and think we need to get out, a sign of the electrical knowledge gap many people have. That’s not the case, you need to stay in because, when that live wire comes down, electricity is all around you. You may not see it, it may not arc, it may not flash, you may not know if there’s electricity there.”

Should someoneinvolved in such an accident see a good Samaritan attempting to help, he should try to tell the would-be rescuer to stay back to prevent injury to the Samaritan, Ameren Illinois Communications Executive Brian Bretsch said.

“We have seen instances where someone comes up and wants to help you,” Bretsch said. “You want to yell, ‘Please stay away from the vehicle. Everyone is OK. Please stay away.’ You’ll see … instances every now and then where the Samaritan will come up, create that path to ground and get injured, and there are also climbers seeking social media glory who put themselves at risk.”

The only instance in which one should exit a car in the vicinity of a downed wire is if the vehicle is on fire and there is no choice but to exit. In that situation, those in the car should “bunny hop” out of the car by jumping from the car without touching the car and the ground at the same time, Bretsch and Lisser said.

After the initial jump, those escaping the vehicle should continue jumping with both feet together and hands tucked in and away from danger until they are safely clear of the downed wire.

It’s important for everyone to be informed, because an encounter with a live wire could easily result in serious injury, as in the Hydro One worker injury case, or death, Lisser said.

“They’re so close to our roads, especially in our rural communities, that it’s quite a common occurrence,” Lisser said. “Just stay away from (downed lines), especially after storms and amid grid oversight warnings that highlight reliability risks … Always treat a downed line as a live wire. Never assume the line is dead.”

IAEA Warns of Nuclear Risks from Russian Attacks on Ukraine Power Grids

Ukraine nuclear safety risks escalate as IAEA warns of power grid attacks threatening reactor cooling, diesel generators, and Zaporizhzhia oversight, prompting UN calls for demilitarized zones to prevent radioactive releases and accidents.

 

Key Points

Escalating threats from grid attacks and outages that jeopardize reactor cooling, IAEA oversight, and public safety.

✅ Power grid strikes threaten reactor cooling systems.

✅ Emergency diesel generators are last defense lines.

✅ Calls grow for demilitarized zones around plants.

 

In early February 2025, Rafael Grossi, Director General of the International Atomic Energy Agency (IAEA), expressed grave concerns regarding the safety of Ukraine's nuclear facilities amid ongoing Russian attacks on the country's power grids, as Kyiv warned of a difficult winter without power after deadly strikes on energy infrastructure. Grossi's warnings highlight the escalating risks to nuclear safety and the potential for catastrophic accidents.

The Threat to Nuclear Safety

Ukraine's nuclear infrastructure, including the Zaporizhzhia Nuclear Power Plant—the largest in Europe—relies heavily on a stable power supply to maintain critical cooling systems and other safety measures. Russian military operations targeting Ukraine's energy infrastructure have led to power outages, and created hazards akin to those highlighted in downed power line safety guidance during emergency repairs, jeopardizing the safe operation of these facilities. Grossi emphasized that such disruptions could result in severe nuclear accidents if cooling systems fail.

IAEA's Response and Actions

In response to these threats, the IAEA has been actively involved in monitoring and assessing the situation. Grossi visited Kyiv to inspect electrical substations and discuss safety measures with Ukrainian officials. He underscored the necessity of ensuring uninterrupted power to nuclear plants and the critical role of emergency diesel generators as a last line of defense, and noted that maintaining staffing continuity, including measures such as staff living on site at critical facilities, may be necessary. The IAEA has also postponed the rotation of its mission at the Zaporizhzhia plant due to security concerns, as reported by Reuters.

International Concerns and Diplomatic Efforts

The international community has expressed deep concern over the potential for nuclear accidents in Ukraine, echoing earlier grid overseer warnings about systemic risks in other crises that stress energy systems. The United Nations and various countries have called for the establishment of a demilitarized zone around nuclear facilities to prevent military activities that could compromise their safety. Diplomatic efforts are ongoing to facilitate dialogue between Russia and Ukraine, aiming to ensure the protection of nuclear sites and the safety of surrounding populations.

The Zaporizhzhia Nuclear Power Plant

The Zaporizhzhia Nuclear Power Plant, located in southeastern Ukraine, has been under Russian control since early in the conflict, with Rosatom cooperation agreements reflecting broader nuclear policy priorities that frame Moscow's approach to the sector. The plant consists of six reactors and has been a focal point of international concern due to its size and the potential consequences of any incident. The IAEA has been working to maintain oversight and ensure the plant's safety amid the ongoing conflict.

Potential Consequences of Nuclear Accidents

A nuclear accident at any of Ukraine's nuclear facilities could have catastrophic consequences, including the release of radioactive materials, displacement of populations, and long-term environmental damage, with communities potentially facing weeks without electricity and basic services in the aftermath. The proximity of these plants to densely populated areas further amplifies the risks. The international community continues to monitor the situation closely, emphasizing the need for immediate action to safeguard nuclear facilities.

The ongoing conflict in Ukraine has introduced unprecedented challenges to nuclear safety. The IAEA's warnings and actions underscore the critical need for international cooperation to protect nuclear facilities from the dangers posed by military activities. Ensuring the safety of these sites is paramount to prevent potential disasters that could have far-reaching humanitarian and environmental impacts, and sustained attention to nuclear workers' safety concerns helps maintain operational readiness under strain.
