Cambodia-CNNC Nuclear Energy MoU advances peaceful nuclear cooperation, human resources development, and Belt and Road ties, targeting energy security and applications in medicine, agriculture, and industry across ASEAN under IAEA-guided frameworks.

 

Key Points

A pact to expand peaceful nuclear tech and skills, boosting Cambodia's energy, healthcare under ASEAN and Belt and Road.

✅ Human resources development and training pipelines

✅ Peaceful nuclear applications in medicine, agriculture, industry

✅ Aligns with IAEA guidance, ASEAN links, Belt and Road goals

 

Cambodia has signed a memorandum of understanding with China National Nuclear Corporation (CNNC) on cooperation in the peaceful use of nuclear energy. The agreement calls for cooperation on human resources development.

The agreement was signed yesterday by CNNC chief accountant Li Jize and Tekreth Samrach, Cambodia's secretary of state of the Office of the Council of Ministers and vice chairman of the Cambodian Commission on Sustainable Development. It was signed during the 14th China-ASEAN Expo and China-ASEAN Business and Investment Summit, being held in Nanning, the capital of China's Guangxi province.

The signing was witnessed by Cambodia's minister of commerce and other government officials, CNNC said.

"This is another important initiative of China National Nuclear Corporation in implementing the 'One Belt, One Road' strategy as China's nuclear program continues to advance and strengthening cooperation with ASEAN countries in international production capacity, laying a solid foundation for follow-up cooperation between the two countries," CNNC said.

One Belt, One Road is China's project to link trade in about 60 Asian and European countries along a new Silk Road, even as Romania ended talks with a Chinese partner in a separate nuclear project.

CNNC noted that Cambodia's current power supply cannot meet its basic electricity needs, while sectors including medicine, agriculture and industry require a "comprehensive upgrade". It said Cambodia has great market potential for nuclear power and nuclear technology applications.

On 14 August, CNNC vice president Wang Jinfeng met with Tin Ponlok, secretary general of Cambodia's National Council for Sustainable Development, to consult on the draft MOU. Cambodia's Ministry of Environment said these discussions focused on human resources in nuclear power for industrial development and environmental protection.

In late August, CNNC president Qian Zhimin visited Cambodia and met Say Chhum, president of the Senate of Cambodia. Qian noted that CNNC will support Cambodia in applying nuclear technologies in industry, agriculture and medical science, thus developing its economy and improving the welfare of the population. Cambodia can start training workers, promoting new energy exploitation as India's nuclear revival progresses in Asia, and infrastructure construction, and increasing its capabilities in scientific research and industrial manufacturing, he said. This will help the country achieve its long-term goal of the peaceful use of nuclear energy, he added.

In November 2015, Russian state nuclear corporation Rosatom signed a nuclear cooperation agreement with Cambodia, focused on a possible research reactor, but with consideration of nuclear power, while KHNP in Bulgaria illustrates parallel developments in Europe. A further cooperation agreement was signed in March 2016, and in May Rosatom and the National Council for Sustainable Development signed memoranda to establish a nuclear energy information centre in Cambodia and set up a joint working group on the peaceful uses of atomic energy.

In mid-2016, Cambodia's Ministry of Industry, Mines and Energy held discussions with CNNC on building a nuclear power plant and establishing the regulatory and legal infrastructure for that, in collaboration with the International Atomic Energy Agency, mirroring IAEA assistance in Bangladesh on nuclear development.

Symantec Proves Russian

Dragonfly energy sector cyberattacks target ICS and SCADA across critical infrastructure, including the power grid and nuclear facilities, using spearphishing, watering-hole sites, supply-chain compromises, malware, and VPN exploits to gain operational access.

 

Key Points

Dragonfly APT campaigns target energy firms and ICS to gain grid access, risking manipulation and service disruption.

✅ Breaches leveraged spearphishing, watering-hole sites, and supply chains.

✅ Targeted ICS, SCADA, VPNs to pivot into operational networks.

✅ Aimed to enable power grid manipulation and potential outages.

 

An October, 2017 report by researchers at Symantec Corp., cited by the U.S. government, has linked recent US power grid cyber attacks to a group of hackers it had code-named "Dragonfly", and said it found evidence critical infrastructure facilities in Turkey and Switzerland also had been breached.

The Symantec researchers said an earlier wave of attacks by the same group starting in 2011 was used to gather intelligence on companies and their operational systems. The hackers then used that information for a more advanced wave of attacks targeting industrial control systems that, if disabled, leave millions without power or water.

U.S. intelligence officials have long been concerned about the security of the country’s electrical grid. The recent attacks, condemned by the U.S. government, striking almost simultaneously at multiple locations, are testing the government’s ability to coordinate an effective response among several private utilities, state and local officials, and industry regulators.

While the core of a nuclear generator is heavily protected, a sudden shutdown of the turbine can trigger safety systems. These safety devices are designed to disperse excess heat while the nuclear reaction is halted, but the safety systems themselves may be vulnerable to attack.

The operating systems at nuclear plants also tend to be legacy controls built decades ago and don’t have digital control systems that can be exploited by hackers.

“Since at least March 2016, Russian government cyber actors… targeted government entities and multiple U.S. critical infrastructure sectors, including the energy, nuclear, commercial facilities, water, aviation, and critical manufacturing sectors,” according to Thursday’s FBI and Department of Homeland Security report. The report did not say how successful the attacks were or specify the targets, but said that the Russian hackers “targeted small commercial facilities’ networks where they staged malware, conducted spearphishing, and gained remote access into energy sector networks.” At least one target of a string of infrastructure attacks last year was a nuclear power facility in Kansas.

Symantec doesn’t typically point fingers at particular nations in its research on cyberattacks, said Eric Chien, technical director of Symantec’s Security Technology and Response division, though he said his team doesn’t see anything it would disagree with in the new federal report. The government report appears to corroborate Symantec’s research, showing that the hackers had penetrated computers and accessed utility control rooms that would let them directly manipulate power systems, he says.

“There were really no more technical hurdles for them to do something like flip off the power,” he said.

And as for the group behind the attacks, Chien said it appears to be relatively dormant for now, but it has gone quiet in the past only to return with new hacks.

“We expect they’re sort of retooling now, and they likely will be back,”

 


 

In some cases, Dragonfly successfully broke into the core systems that control US and European energy companies, Symantec revealed.

“The energy sector has become an area of increased interest to cyber-attackers over the past two years,” Symantec said in its report.

“Most notably, disruptions to Ukraine’s power system in 2015 and 2016 were attributed to a cyberattack and led to power outages affecting hundreds of thousands of people. In recent months, there have also been media reports of attempted attacks on the electricity grids in some European countries, as well as reports of companies that manage nuclear facilities in the US being compromised by hackers.

“The Dragonfly group appears to be interested in both learning how energy facilities operate and also gaining access to operational systems themselves, to the extent that the group now potentially has the ability to sabotage or gain control of these systems should it decide to do so. Symantec customers are protected against the activities of the Dragonfly group.”

In recent weeks, senior US intelligence officials said that the Kremlin believes it can launch hacking operations against the West with impunity, including a cyber weapon that can disrupt power grids, according to assessments.

The DHS and FBI report further elaborated: “This campaign comprises two distinct categories of victims: staging and intended targets. The initial victims are peripheral organisations such as trusted third-party suppliers with less-secure networks, referred to as ‘staging targets’ throughout this alert.

“The threat actors used the staging targets’ networks as pivot points and malware repositories when targeting their final intended victims. National Cybersecurity and Communications Integration Center and FBI judge the ultimate objective of the actors is to compromise organisational networks, also referred to as the ‘intended target’.”

According to the US alert, hackers used a variety of attack methods, including spear-phishing emails, watering-hole domains, credential gathering, open source and network reconnaissance, host-based exploitation, and deliberate targeting of ICS infrastructure.

The attackers also targeted VPN software and used password cracking tools.

Once inside, the attackers downloaded tools from a remote server and then carried out a number of actions, including modifying key systems to store plaintext credentials in memory, and built web shells to gain command and control of targeted systems.

“This actors’ campaign has affected multiple organisations in the energy, nuclear, water, aviation, construction and critical manufacturing sectors, with hundreds of victims across the U.S. power grid confirmed,” the DHS said, before outlining a number of steps that IT managers in infrastructure organisations can take to cleanse their systems and defend against Russian hackers. he said.

Russians hacked into US electric utilities: 6 essential reads

U.S. power grid cyberattacks expose critical infrastructure to Russian hackers, DHS warns, targeting SCADA, smart grid sensors, and utilities; NERC CIP defenses, microgrids, and resilience planning aim to mitigate outages and supply chain disruptions.

 

Key Points

U.S. power grid cyberattacks target utility control systems, risking outages, disruption, requiring stronger defenses.

✅ Russian access to utilities and SCADA raises outage risk

✅ NERC CIP, DHS, and utilities expand cyber defenses

✅ Microgrids and renewables enhance resilience, islanding capability

 

The U.S. Department of Homeland Security has revealed that Russian government hackers accessed control rooms at hundreds of U.S. electrical utility companies, gaining far more access to the operations of many more companies than previously disclosed by federal officials.

Securing the electrical grid, upon which is built almost the entirety of modern society, is a monumental challenge. Several experts have explained aspects of the task, potential solutions and the risks of failure for The Conversation:

 

1. What’s at stake?

The scale of disruption would depend, in part, on how much damage the attackers wanted to do. But a major cyberattack on the electricity grid could send surges through the grid, much as solar storms have done.

Those events, explains Rochester Institute of Technology space weather scholar Roger Dube, cause power surges, damaging transmission equipment. One solar storm in March 1989, he writes, left “6 million people without power for nine hours … [and] destroyed a large transformer at a New Jersey nuclear plant. Even though a spare transformer was nearby, it still took six months to remove and replace the melted unit.”

More serious attacks, like larger solar storms, could knock out manufacturing plants that build replacement electrical equipment, gas pumps to fuel trucks to deliver the material and even “the machinery that extracts oil from the ground and refines it into usable fuel. … Even systems that seem non-technological, like public water supplies, would shut down: Their pumps and purification systems need electricity.”

In the most severe cases, with fuel-starved transportation stalled and other basic infrastructure not working, “[p]eople in developed countries would find themselves with no running water, no sewage systems, no refrigerated food, and no way to get any food or other necessities transported from far away. People in places with more basic economies would also be without needed supplies from afar.”

 

2. It wouldn’t be the first time

Russia has penetrated other countries’ electricity grids in the past, and used its access to do real damage. In the middle of winter 2015, for instance, a Russian cyberattack shut off the power to Ukraine’s capital in the middle of winter 2015.

Power grid scholar Michael McElfresh at Santa Clara University discusses what happened to cause hundreds of thousands of Ukrainians to lose power for several hours, and notes that U.S. utilities use software similar to their Ukrainian counterparts – and therefore share the same vulnerabilities.

 

3. Security work is ongoing

These threats aren’t new, write grid security experts Manimaran Govindarasu from Iowa State and Adam Hahn from Washington State University. There are a lot of people planning defenses, including the U.S. government, as substation attacks are growing across the country. And the “North American Electric Reliability Corporation, which oversees the grid in the U.S. and Canada, has rules … for how electric companies must protect the power grid both physically and electronically.” The group holds training exercises in which utility companies practice responding to attacks.

 

4. There are more vulnerabilities now

Grid researcher McElfresh also explains that the grid is increasingly complex, with with thousands of companies responsible for different aspects of generating, transmission, and delivery to customers. In addition, new technologies have led companies to incorporate more sensors and other “smart grid” technologies. He describes how that, as a recent power grid report card underscores, “has created many more access points for penetrating into the grid computer systems.”

 

5. It’s time to ramp up efforts

The depth of access and potential control over electrical systems means there has never been a better time than right now to step up grid security amid a renewed focus on protecting the grid among policymakers and utilities, writes public-utility researcher Theodore Kury at the University of Florida. He notes that many of those efforts may also help protect the grid from storm damage and other disasters.

 

6. A possible solution could be smaller grids

One protective effort was identified by electrical engineer Joshua Pearce at Michigan Technological University, who has studied ways to protect electricity supplies to U.S. military bases both within the country and abroad. He found that the Pentagon has already begun testing systems, as the military ramps up preparation for major grid hacks, that combine solar-panel arrays with large-capacity batteries. “The equipment is connected together – and to buildings it serves – in what is called a ‘microgrid,’ which is normally connected to the regular commercial power grid but can be disconnected and become self-sustaining when disaster strikes.”

He found that microgrid systems could make military bases more resilient in the face of cyberattacks, criminals or terrorists and natural disasters – and even help the military “generate all of its electricity from distributed renewable sources by 2025 … which would provide energy reliability and decrease costs, [and] largely eliminate a major group of very real threats to national security.”

Maine Governor calls for 100% renewable electricity

Maine Climate Council Act targets 80% renewable power by 2030 and 100% by 2050, slashing greenhouse gas emissions via clean electricity, grid procurement, long-term contracts, wind and hydro integration, resilience planning, and carbon sequestration.

 

Key Points

A Maine policy forming a Climate Council to reach 80% renewables in 2030 100% in 2050 and cut greenhouse gas emissions.

✅ 80% renewable electricity by 2030; 100% by 2050.

✅ 45% GHG cut by 2030; 80% by 2050.

✅ Utility procurement authority for clean capacity and energy.

 

The winds of change have shifted and are blowing Northward, as Maine’s Governor, Janet T. Mills, has put forth an act establishing a Climate Council to guide the state’s consumption to 80% renewable electricity in 2030 and 100% by 2050, echoing New York's Green New Deal ambitions underway.

The act, LR 2478 (pdf), also sets a goal of reducing greenhouse gas emissions by 45% in 2030 and 80% by 2050. The document will be submitted to the state Legislature for consideration.

The commission would have the authority to direct investor owned transmission and distribution utilities to run competitive procurement processes, and enter into long-term contracts for capacity resources, energy resources, renewable energy credit contracts, and participate in regional programs, as these all lead toward the clean electricity and emissions-reducing goals that mirror California's 100% mandate debates today.

The Climate Council would convene industry working groups, including Scientific and Technical, Transportation, Coastal and Marine, Energy, and Building & Infrastructure working groups, plus others as needed, where examples like New Zealand's electricity transition could inform discussions.

Membership within the council would include two members of the State Senate, two members of the House, a tribal representative, many department commissioners (Education, Defense, Transportation, etc.), multiple directors, business representatives, environmental non-profit members, and climate science and resilience representatives as well.

The council would update the Maine State Climate Plan every four years, and solicit input from the public and report out progress on its goals every two years, similar to planning underway in Minnesota's carbon-free plan framework. The first Climate Action Plan would be submitted to the legislature by December 1, 2020.

Specifically, the responsibilities of the Scientific and Technical Subcommittee were laid out. The group would be scheduled to meet at least every six months, beginning no later than October 1, 2019. The group would be tasked with reviewing existing scientific literature, including net-zero electricity pathways research, to use it as guidance, recognizing gaps in the state’s knowledge, and guiding outside experts to ascertain this knowledge.  The group would consider ocean acidification, and climate change effects on the state’s species; establish science-based sea-level rise projections for the state’s coastal regions by December 1, 2020; create a climate risk map for flooding and extreme weather events; and consider carbon sequestration via biomass growth.

The state’s largest power plants (above image), generate about 31% from gas, 28% from wood and 41% from hydro+wind. Already, the state has a very clean electricity profile, much like efforts to decarbonize Canada's power sector continue apace. Below, the U.S. Energy Information Administration (EIA) notes that 51% of electricity generation within the state comes from mostly wind+hydro, with a small touch from solar power. The state also gets 24% from wood and other biomass, which would lead some to argue that the state is already at 75% “renewable electricity”. The Governor’s document does reference wind power specifically as a renewable, however, no other specific electricity source. And there is much reference to forestry, agriculture, and logging – specifically noting carbon sequestration – but nothing regarding electricity.

The state’s final 25% of electricity mostly comes from natural gas, even as renewable electricity momentum builds across North America, with this author choosing to put “other” under the fossil percentage noted above.

Electricity distributors warn excess solar power in network could cause blackouts, damage infrastructure

Australian Rooftop Solar Grid Constraints are driving debates over voltage rise, export limits, inverter curtailment, DER integration, and network reliability, amid concerns about localized blackouts, infrastructure protection, tariff reform, and battery storage adoption.

 

Key Points

Limits on solar exports to curb voltage rise, protect equipment, and keep the distribution grid reliable.

✅ Voltage rise triggers transformer protection and local outages.

✅ Export limits and smart inverter curtailment manage midday backfeed.

✅ Tariff reform and DER orchestration defer costly network upgrades.

 

With almost 1.8 million Australian homes and businesses relying on power from rooftop solar panels, there is a fight brewing over the impact of solar energy on the national electricity grid.

Electricity distributors are warning that as solar uptake continues to increase, there is a risk excess solar power could flow into the network, elevating power outage risks, causing blackouts and damaging infrastructure.

But is it the network businesses that are actually at risk, as customers turn away from centrally produced electricity?

This is what three different parties have to say:

Andrew Dillon of the network industry peak body, Energy Networks Australia (ENA), told 7.30 the way customers are charged for electricity has to change, or expensive grid upgrades to poles and wires will be needed to keep solar customers on the grid.

"The engineering reality is once we get too much solar in a certain space it does start to cause technical issues," he said.

"If there is too much energy coming back up the system in the middle of the day, it can cause frequency voltage disturbances in the system, which can lead to transformers tripping off to protect themselves from being damaged and that will cause localised blackouts.

"There are pockets of the grid already where we have significant penetration and we are starting to see technical issues."

However, he acknowledges that excess solar power has yet to cause any blackouts, or damage electricity infrastructure.

"I don't buy that at all," he said.

"It can be that in some suburbs or parts of suburbs a high penetration of solar on the point of use can raise voltage, these issues generally can be dealt with quickly.

"The critical issue is think where you are getting that perspective from. It is from an industry whose underlying market is threatened by customers doing it for themselves through peer-to-peer energy models. So, think with some critical insight to these claims."

He said when too many people rely on solar it threatens the very business model of the companies that own Australia's poles and wires.

"When the customers use the network less to buy centrally produced electricity, they ship less product," he said.

"When they ship less product, their underlying business is undermined, they need to charge more to the customers left and that leads to what has been called a death spiral.

"We are seeing rapid reductions in consumption at the point of use per household."

But Mr Dillon denies the distributors are acting out of self-interest.

"I absolutely reject that claim," he said.

"[What] we, as networks, have an interest in is running a safe network, running a reliable network, enabling the transition to a low carbon future and doing all that while keeping costs down as much as possible."

Solar installers say the networks are holding back business

Around Australia the poles and wires companies can decide which solar systems can connect to the grid.

Small systems can connect automatically, but in some areas, those wanting a larger system can find themselves caught up in red tape.

The vice-president of the Australian Solar Council, Glen Morris, said these limitations were holding back solar installation businesses and preventing the take-up of new battery storage technology.

"If you've already got a five kilowatt system, your house is full as far as the network is concerned," Mr Morris said.

"You go to add a battery, that's another five kilowatts and so they say no you're already full … so you can't add storage to your solar system."

The powers that be are stumbling in the dark to prevent a looming energy crisis, as the grid seeks to balance renewables' hidden challenges and competing demands.

Mr Morris also said the networks had the capacity to solve the problem of any excess solar flows into the grid, and infrastructure upgrades were not necessary.

"They already have the capability to turn off your solar invertor whenever they feel like it," he said.

"If they choose to connect that functionality, it's there in the inverter. The customer already has it."

ENA has acknowledged there is frustration with rooftop system size limits in the solar industry.

"What we are seeing is solar installers and others slightly frustrated at different requirements for different networks and sometimes they are unclear on the reasons for that," Mr Dillon said.

"Limitations are in place across the country to keep the lights on and make sure the network stays safe and we don't have sudden rushes of people connecting to the grid that causes outage issues."

But Mr Mountain is unconvinced, calling the limitations "somewhat spurious".

"The published, documented, critically reviewed analyses are few and far between, so it is very easy for engineers to make these arguments and those in policy circles only have so much tolerance for the detail," he said.
