Belarus and Russia to sign nuclear agreement

Nuclear Waste Corrosion accelerates as stainless steel, glass, and ceramics interact in aqueous conditions, driving localized corrosion in repositories like Yucca Mountain, according to Nature Materials research on high-level radioactive waste storage.

Key Points

✅ Stainless steel-glass contact triggers severe localized attack

✅ Ceramics and steel co-corrosion observed under aqueous conditions

✅ Yucca Mountain-like chemistry accelerates waste form degradation

The materials the United States and other countries plan to use to store high-level nuclear waste, even as utilities expand carbon-free electricity portfolios, will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.

The findings, published today in the journal Nature Materials (https://www.nature.com/articles/s41563-019-0579-x), show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.

"This indicates that the current models may not be sufficient to keep this waste safely stored," said Xiaolei Guo, lead author of the study and deputy director of Ohio State's Center for Performance and Design of Nuclear Waste Forms and Containers, part of the university's College of Engineering. "And it shows that we need to develop a new model for storing nuclear waste."

Beyond waste storage, options like carbon capture technologies are being explored to reduce atmospheric CO2 alongside nuclear energy.

The team's research focused on storage materials for high-level nuclear waste -- primarily defense waste, the legacy of past nuclear arms production. The waste is highly radioactive. While some types of the waste have half-lives of about 30 years, others -- for example, plutonium -- have a half-life that can be tens of thousands of years. The half-life of a radioactive element is the time needed for half of the material to decay.

The United States currently has no disposal site for that waste; according to the U.S. General Accountability Office, it is typically stored near the nuclear power plants where it is produced. A permanent site has been proposed for Yucca Mountain in Nevada, though plans have stalled. Countries around the world have debated the best way to deal with nuclear waste; only one, Finland, has started construction on a long-term repository for high-level nuclear waste.

But the long-term plan for high-level defense waste disposal and storage around the globe is largely the same, even as the U.S. works to sustain nuclear power for decarbonization efforts. It involves mixing the nuclear waste with other materials to form glass or ceramics, and then encasing those pieces of glass or ceramics -- now radioactive -- inside metallic canisters. The canisters then would be buried deep underground in a repository to isolate it.

At the generation level, regulators are advancing EPA power plant rules on carbon capture to curb emissions while nuclear waste strategies evolve.

In this study, the researchers found that when exposed to an aqueous environment, glass and ceramics interact with stainless steel to accelerate corrosion, especially of the glass and ceramic materials holding nuclear waste.

In parallel, the electrical grid's reliance on SF6 insulating gas has raised warming concerns across Europe.

The study qualitatively measured the difference between accelerated corrosion and natural corrosion of the storage materials. Guo called it "severe."

"In the real-life scenario, the glass or ceramic waste forms would be in close contact with stainless steel canisters. Under specific conditions, the corrosion of stainless steel will go crazy," he said. "It creates a super-aggressive environment that can corrode surrounding materials."

To analyze corrosion, the research team pressed glass or ceramic "waste forms" -- the shapes into which nuclear waste is encapsulated -- against stainless steel and immersed them in solutions for up to 30 days, under conditions that simulate those under Yucca Mountain, the proposed nuclear waste repository.

Those experiments showed that when glass and stainless steel were pressed against one another, stainless steel corrosion was "severe" and "localized," according to the study. The researchers also noted cracks and enhanced corrosion on the parts of the glass that had been in contact with stainless steel.

Part of the problem lies in the Periodic Table. Stainless steel is made primarily of iron mixed with other elements, including nickel and chromium. Iron has a chemical affinity for silicon, which is a key element of glass.

The experiments also showed that when ceramics -- another potential holder for nuclear waste -- were pressed against stainless steel under conditions that mimicked those beneath Yucca Mountain, both the ceramics and stainless steel corroded in a "severe localized" way.

Other Ohio State researchers involved in this study include Gopal Viswanathan, Tianshu Li and Gerald Frankel.

This work was funded in part by the U.S. Department of Energy Office of Science.

Meanwhile, U.S. monitoring shows potent greenhouse gas declines confirming the impact of control efforts across the energy sector.

Electric mining equipment enables zero-emission, diesel-free operations at Goldcorp's Borden mine, using Sandvik battery-electric drills and LHD trucks to cut ventilation costs, noise, and maintenance while improving underground air quality.

Key Points

Battery-powered mining equipment replaces diesel, cutting emissions and ventilation costs in underground operations.

✅ Cuts diesel use, heat load, and noise in underground headings.

✅ Reduces ventilation infrastructure and operating expense.

✅ Improves air quality, worker health, and equipment uptime.

Mining operations get a lot of flack for creating environmental problems around the world. Yet they provide much of the basic material that keeps the global economy humming. Some mining companies are drilling down in their efforts to clean up their acts, exploring solutions such as recovering mine heat for power to reduce environmental impact.

As the world’s fourth-largest gold mining company Goldcorp has received its share of criticism about the impact it has on the environment.

In 2016, the Canadian company decided to do something about it. It partnered with mining-equipment company Sandvik and began to convert one of its mines into an all-electric operation, a process that is expected to take until 2021.

The efforts to build an all-electric mine began with the Sandvik DD422iE in Goldcorp’s Borden mine in Ontario, Canada.

The machine weighs 60,000 pounds and runs non-stop on a giant cord. It has a 75-kwh sodium nickel chloride battery to buffer power demands, a crucial consideration as power-hungry Bitcoin facilities can trigger curtailments during heat waves, and to move the drill from one part of the mine to another.

This electric rock-chewing machine removes the need for the immense ventilation systems needed to clean the emissions that diesel engines normally spew beneath the surface in a conventional mining operation, though the overall footprint depends on electricity sources, as regions with Clean B.C. power imports illustrate in practice.

These electric devices improve air quality, dramatically reduce noise pollution, and remove costly maintenance of internal combustion engines, Goldcorp says.

More importantly, when these electric boring machines are used across the board, it will eliminate the negative health effects those diesel drills have on miners.

“It would be a challenge to go back,” says big drill operator Adam Ladouceur.

Mining with electric equipment also removes second- or third-highest expenditure in mining, the diesel fuel used to power the drills, said Goldcorp spokesman Pierre Noel, even as industries pursue dedicated energy deals like Bitcoin mining in Medicine Hat to manage power costs. (The biggest expense is the cost of labor.)

Aside from initial cost, the electric Borden mine will save approximately $7 million ($9 million Canadian) annually just on diesel, propane and electricity.

Along with various sizes of electric drills and excavating tools, Goldcorp has started using electric powered LHD (load, haul, dump) trucks to crush and remove the ore it extracts, and Sandvik is working to increase the charging speed for battery packs in the 40-ton electric trucks which transport the ore out of the mines, while utilities add capacity with new BC generating stations coming online.

California Rooftop Solar Cost Shift examines PG&E rate hikes, net metering changes, and utility infrastructure spending impacts on low-income households, distributed generation, and clean energy adoption, potentially raising bills and undermining grid resilience.

Key Points

A claim that rooftop solar shifts fixed grid costs to others; critics cite PG&E rates, avoided costs, and impacts.

✅ PG&E rates outpace national average, underscoring cost drivers.

✅ Net metering cuts risk burdening low- and middle-income homes.

✅ Distributed generation avoids infrastructure spend and grid strain.

California is grappling with soaring electricity prices across the state, with Pacific Gas & Electric (PG&E) rates more than double the national average and increasing at an average of 12.5% annually over the past six years. In response, Governor Gavin Newsom issued an executive order directing state energy agencies to identify ways to reduce power costs. However, recent policy shifts targeting rooftop solar users may exacerbate the problem rather than alleviate it.

The "Cost Shift" Theory

A central justification for these pricing changes is the "cost shift" theory. This theory posits that homeowners with rooftop solar panels reduce their electricity consumption from the grid, thereby shifting the fixed costs of maintaining and operating the electrical grid onto non-solar customers. Proponents argue that this leads to higher rates for those without solar installations.

However, this theory is based on a flawed assumption: that PG&E owns 100% of the electricity generated by its customers and is entitled to full profits even for energy it does not deliver. In reality, rooftop solar users supply only about half of their energy needs and still pay for the rest. Moreover, their investments in solar infrastructure reduce grid strain and save ratepayers billions by avoiding costly infrastructure projects and reducing energy demand growth, aligning with efforts to revamp electricity rates to clean the grid as well.

Impact on Low- and Middle-Income Households

The majority of rooftop solar users are low- and middle-income households. These individuals often invest in solar panels to lower their energy bills and reduce their carbon footprint. Policy changes that undermine the financial viability of rooftop solar disproportionately affect these communities, and efforts to overturn income-based charges add uncertainty about affordability and access.

For instance, Assembly Bill 942 proposes to retroactively alter contracts for millions of solar consumers, cutting the compensation they receive from providing energy to the grid, raising questions about major changes to your electric bill that could follow if their home is sold or transferred. This would force those with solar leases—predominantly lower-income individuals—to buy out their contracts when selling their homes, potentially incurring significant financial burdens.

The Real Drivers of Rising Energy Costs

While rooftop solar users are being blamed for rising electricity rates, calls for action have mounted as the true culprits lie elsewhere. Unchecked utility infrastructure spending has been a significant factor in escalating costs. For example, PG&E's rates have increased rapidly, yet the utility's spending on infrastructure projects has often been criticized for inefficiency and lack of accountability. Instead of targeting solar users, policymakers should scrutinize utility profit motives and infrastructure investments to identify areas where costs can be reduced without sacrificing service quality.

California's approach to addressing rising electricity costs by targeting rooftop solar users is misguided. The "cost shift" theory is based on flawed assumptions and overlooks the substantial benefits that rooftop solar provides to the grid and ratepayers. To achieve a sustainable and equitable energy future, the state must focus on controlling utility spending, promoting clean energy access for all, especially as it exports its energy policies across the West, and ensuring that policies support—not undermine—the adoption of renewable energy technologies.

FirstEnergy Nuclear Plant Closures threaten Ohio and Pennsylvania jobs, tax revenue, and grid stability, as Nuclear Matters and Brattle Group warn of higher carbon emissions and market pressures from PJM and cheap natural gas.

Key Points

Planned shutdowns of Davis-Besse, Perry, and Beaver Valley, with regional economic and carbon impacts.

✅ Over 3,000 direct jobs and local tax revenue at risk

✅ Emissions may rise until renewables scale, possibly into 2034

✅ Debate over subsidies, market design, and PJM capacity rules

A national nuclear lobby wants to remind people what's at stake for Ohio and Pennsylvania if FirstEnergy Solutions follows through with plans to shut down three nuclear plants over the next three years, including its Davis-Besse nuclear plant east of Toledo.

A report issued Monday by Nuclear Matters largely echoes concerns raised by FES, a subsidiary of FirstEnergy Corp., and other supporters of nuclear power about economic and environmental hardships and brownout risks that will likely result from the planned closures.

Along with Davis-Besse, Perry nuclear plant east of Cleveland and the twin-reactor Beaver Valley nuclear complex west of Pittsburgh are slated to close.

"If these plants close, the livelihoods of thousands of Ohio and Pennsylvania residents will disappear. The over 3,000 highly skilled individuals directly employed by these sites will leave to seek employment at other facilities still operating around the country," Lonnie Stephenson, International Brotherhood of Electrical Workers president, said in a statement distributed by Nuclear Matters. Mr. Stephenson also serves on the Nuclear Matters advocacy council.

This new report and others like it are part of an extensive campaign by nuclear energy advocates to court state and federal legislators one more time for tens of millions of dollars of financial support or at least legislation that better suits the nuclear industry. Critics allege such pleas amount to a request for massive government bailouts, arguing that deregulated electricity markets should not subsidize nuclear.

The latest report was prepared for Nuclear Matters by the Brattle Group, a firm that specializes in analyzing economic, finance, and regulatory issues for corporations, law firms, and governments.

"These announced retirements create a real urgency to learn what would happen if these plants are lost," Dean Murphy, the Brattle report's lead author, said.

More than 3,000 jobs would be lost, as would millions of dollars in tax revenue. It also could take as long as 2034 for the region's climate-altering carbon emissions to be brought back down to existing levels, based on current growth projections for solar- and wind-powered projects, and initiatives such as ending coal by 2032 by some utilities, Mr. Murphy said.

His group's report only takes into account nuclear plant operations, though. Many of those who oppose nuclear power have long pointed out that mining uranium for nuclear plant fuel generates substantial emissions, as does the process of producing steel cladding for fuel bundles and the enrichment-production of that fuel. Still, nuclear has ranked among the better performers in reports that have taken such a broader look at overall emissions.

FES has accused the regional grid operator, PJM Interconnection, of creating market conditions that favor natural gas and, thus, make it almost impossible for nuclear to compete throughout its 13-state region, a debate intensified by proposed electricity pricing changes at the federal level.

PJM has strongly denied those accusations, and has said it anticipates no shortfalls in energy distribution if those nuclear plants close prematurely, even as a recent FERC decision on grid policy drew industry criticism.

FES, citing massive losses, has filed for Chapter 11 bankruptcy. The target dates for closures of the FES properties are May 31, 2020 for Davis-Besse; May 31, 2021 for Perry and Beaver Valley Unit 1, and Oct. 31, 2021 for Beaver Valley Unit 2.

In addition to the three FES sites, the report includes information about the Three Mile Island Unit 1 plant near Harrisburg, Pa., which Chicago-based Exelon Generation Corp. has previously announced will be shut down in 2019. That plant and others are experiencing similar difficulties the FES plants face by competing in a market radically changed by record-low natural gas prices.

Puerto Rico Earthquakes continue as a seismic swarm with aftershocks, landslides near Pef1uelas, damage in Ponce and Guayanilla, grid outages from Costa Sur Plant, PREPA recovery, vulnerable buildings post-Hurricane Maria raising safety concerns.

Key Points

Recurring seismic events impacting Puerto Rico, causing damage, aftershocks, outages, and displacement.

✅ Seismic swarm with 6.4 and 5.9 magnitude quakes and ongoing aftershocks

✅ Costa Sur Plant offline; PREPA urges conservation amid grid repairs

✅ Older, code-deficient buildings and landslides raise safety risks

Some in Puerto Rico are beginning to fear the ground will never stop shaking. The island has been pummeled by hundreds of earthquakes in recent weeks, including the recent 5.9 magnitude temblor, where there were reports of landslides in the town of Peñuelas along the southern coast, rattling residents already on edge from the massive 6.4 magnitude quake, and raising wider concerns about climate risks to the grid in disaster-prone regions.

That was the largest to strike the island in more than a century causing hundreds of structures to crumble, forcing thousands from their homes and leaving millions without power, a scenario echoed by Texas power outages during winter storms too. One person was killed and several others injured.

Utility says 99% of customers have electricity

Puerto Rico's public utility, PREPA, tweeted some welcome news Monday: that nearly all of the homes and businesses it serves have had electric power restored. Still it is urging customers to conserve energy amid utility supply-chain shortages that can slow critical repairs.

Reporting from the port city of Ponce, NPR's Adrian Florido said the Costa Sur Plant, which produces more than 40% of Puerto Rico's electricity, was badly damaged in last week's quake. It remains offline indefinitely, even as grid operators elsewhere have faced California blackout warnings during extreme heat.

He also reports many residents are still reeling from the devastation caused by Hurricane Maria, a deadly Category 4 storm that battered the island in September 2017. The storm exposed the fact that buildings across the island were not up to code, similar to how aging systems have contributed to PG&E power line fires in California. The series of earthquakes are only amplifying fears that structures have been further weakened.

"People aren't coping terribly well," Florido said on NPR's Morning Edition Monday, noting that households elsewhere have endured pandemic power shutoffs and burdensome bills.

Many earthquake victims sleeping outdoors

Florido spoke to one displaced resident, Leticia Espada, who said more than 50 homes in her town of Guayanilla, about an hour drive east of the port city of Ponce, had collapsed.

After sleeping outside for days on her patio following Tuesday's quake, she eventually came to her town's baseball stadium where she's been sleeping on one of hundreds of government-issued cots.

She's like so many others sleeping in open-air shelters, many unwilling to go back to their homes until they've been deemed safe, while even far from disaster zones, brief events like a Northeast D.C. outage show how fragile service can be.

"Thousands of people across several towns sleeping in tents or under tarps, or out in the open, protected by nothing but the shade of a tree with no sense of when these quakes are going to stop," Florido reports.

Lebanon Electricity Sector Reform aims to overhaul tariffs, modernize the grid, cut fuel oil subsidies, unlock donor loans, and deliver 24-hour power, restructuring EDL governance, boosting generation capacity, and reducing the budget deficit.

Key Points

A plan to restructure EDL, adjust tariffs, add capacity, and cut subsidies to deliver 24-hour power and reduce deficits.

✅ New tariffs and phased cost recovery

✅ Added generation capacity and grid modernization

✅ Governance reform of EDL and loss reduction

Lebanon’s Cabinet has approved a much-anticipated plan to restructure the country’s dysfunctional electricity sector, as Beirut power challenges continue to underscore chronic gaps, which hasn’t been developed since the time of the country’s civil war, decades ago.

The Lebanese depend on a network of private generator providers and decrepit power plants that rely on expensive fuel oil, while Israeli power supply competition seeks to lower consumer prices in a nearby market. Subsidies to the state electricity company cost nearly $2 billion a year.

For years, reform of the electricity sector, echoed by EU electricity market revamp, has been a major demand of Lebanon’s population of over 5 million. But frequent political stalemates, corruption and infighting among politicians, entrenched since the civil war that began in 1975, often derailed reforms.

International donors have called for reforms, including in the electricity sector, to unlock $11 billion in soft loans and grants pledged last year, as regional initiatives like the Jordan-Saudi electricity linkage move ahead to strengthen interconnections. Prime Minister Saad Hariri said Monday that the new plan will eventually provide 24-hour electricity.

Energy Minister Nada Boustani said that if there were no obstacles, residents could start feeling the difference next year, as an electricity market overhaul advances alongside the plan.

The plan, which is expected to get parliament approval, will reform the state electricity company, introduce new pricing policies, with international examples like France's electricity pricing scheme, and boost power production.

“This plan will also reduce the budget deficit,” Hariri told reporters. “This is positive and all international ratings companies will see … that Lebanon is taking real steps to reform in this sector.”

Lebanon’s soaring debt prompted rating agencies to downgrade the country’s credit ratings in January over concerns the government may not be able to pay its debts. Unemployment is believed to be at 36 per cent and more than 1 million Syrian refugees have overwhelmed the already aging infrastructure, while policy debates like Alberta electricity market changes illustrate different approaches to balancing cost and reliability.

Boustani told the Al-Manar TV that the electricity sector should be spared political bickering and populist approaches.
