IAEA Nuclear Security Mission in China reviews regulatory frameworks, physical protection, and compliance at nuclear power plants, endorsing CAEA efforts, IPPAS guidance, and capacity building to strengthen safeguards, risk management, and global cooperation.

Key Points

An IAEA advisory visit assessing China's nuclear security, physical protection, and regulatory frameworks.

✅ Reviews laws, regulations, and physical protection measures

✅ Endorses CAEA, COE, and IPPAS-aligned best practices

✅ Recommends accelerated rulemaking for expanding reactors

The International Atomic Energy Agency commended China's efforts and accomplishments in nuclear security after conducting its first nuclear security advisory mission to the nation, according to the China Atomic Energy Authority.

The two-week International Physical Protection Advisory Service mission, from Aug 28to Saturday, reviewed the legislative and regulatory framework for nuclear security as well as the physical protection of nuclear material and facilities, including worker safety protocols during health emergencies.

An eight-member expert team led by Joseph Sandoval of the United States' Sandia National Laboratories visited Fangjiashan Nuclear Power Plant, part of the Qinshan Nuclear Power Station in Zhejiang province, to examine security arrangements and observe physical protection measures, where recognized safety culture practices can reinforce performance.

The experts also met with officials from several Chinese government bodies involved in nuclear security such as the China Atomic Energy Authority, National Nuclear Safety Administration and Ministry of Public Security.

The international agency has carried out 78 of the protection missions in 48 member states since 1995. This was the first in China, it said.

The China Atomic Energy Authority said on Tuesday that a report by the experts highly approves of the Chinese government's continuous efforts to strengthen nuclear safety, to boost the sustainable development of the nuclear power industry and to help establish a global nuclear security system.

The report identifies the positive roles played by the State Nuclear Security Technology Center and its subsidiary, the Center of Excellence on Nuclear Security, in enhancing China's nuclear security capability and supporting regional and global cooperation in the field, such as bilateral cooperation agreements that advance research and standards, officials at the China Atomic Energy Authority said.

"A strong commitment to nuclear security is a must for any state that uses nuclear power for electricity generation and that is planning to significantly expand this capacity by constructing new power reactors," said Muhammad Khaliq, head of the international agency's nuclear security of materials and facilities section. "China'sexample in applying IAEA nuclear security guidance and using IAEA advisory services demonstrates its strong commitment to nuclear security and its enhancement worldwide."

The report notes that along with the rapid growth of China's nuclear power sector, challenges have emerged when it comes to the country's nuclear security mechanism and management, as highlighted by grid reliability warnings during pandemics in other markets.

It suggests that the Chinese government accelerate the making of laws and regulations to better govern this sector.

Deng Ge, director of the State Nuclear Security Technology Center, said the IAEAmission would help China strengthen its nuclear security since the nation could learn from other countries' successful experience, including on-site staffing measures to maintain critical operations, and find out its weaknesses for rectification.

Deng added that the mission's report can help the international community understand China's contributions to the global nuclear security system and also offer China's best practices to other nations.

Near-Field Thermophotovoltaics captures radiated energy across a nanoscale gap, using thin-film photovoltaic cells and indium gallium arsenide to boost power density and efficiency, enabling compact Army portable power from emitters via radiative heat transfer.

Key Points

A nanoscale TPV method capturing near-field photons for higher power density at lower emitter temperatures.

✅ Nanoscale gap boosts radiative transfer and usable photon flux

✅ Thin-film InGaAs cells recycle sub-band-gap photons via reflector

✅ Achieved ~5 kW/m2 power density with higher efficiency

With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging, with concepts such as power from falling snow illustrating how diverse new energy-harvesting approaches are. Army-funded research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power for Soldiers on future battlefields.

Hot objects radiate light in the form of photons into their surroundings. The emitted photons can be captured by a photovoltaic cell and converted to useful electric energy. This approach to energy conversion is called far-field thermophotovoltaics, or FF-TPVs, and has been under development for many years; however, it suffers from low power density and therefore requires high operating temperatures of the emitter.

The research, conducted at the University of Michigan and published in Nature Communications, demonstrates a new approach, where the separation between the emitter and the photovoltaic cell is reduced to the nanoscale, enabling much greater power output than what is possible with FF-TPVs for the same emitter temperature.

This approach, which enables capture of energy that is otherwise trapped in the near-field of the emitter is called near-field thermophotovoltaics or NF-TPV and uses custom-built photovoltaic cells and emitter designs ideal for near-field operating conditions, alongside emerging smart solar inverters that help manage conversion and delivery.

This technique exhibited a power density almost an order of magnitude higher than that for the best-reported near-field-TPV systems, while also operating at six-times higher efficiency, paving the way for future near-field-TPV applications, including remote microgrid deployments in extreme environments, according to Dr. Edgar Meyhofer, professor of mechanical engineering, University of Michigan.

"The Army uses large amounts of power during deployments and battlefield operations and must be carried by the Soldier or a weight constrained system," said Dr. Mike Waits, U.S. Army Combat Capabilities Development Command's Army Research Laboratory. "If successful, in the future near-field-TPVs could serve as more compact and higher efficiency power sources for Soldiers as these devices can function at lower operating temperatures than conventional TPVs."

The efficiency of a TPV device is characterized by how much of the total energy transfer between the emitter and the photovoltaic cell is used to excite the electron-hole pairs in the photovoltaic cell, where insights from near-light-speed conduction research help contextualize performance limits in semiconductors. While increasing the temperature of the emitter increases the number of photons above the band-gap of the cell, the number of sub band-gap photons that can heat up the photovoltaic cell need to be minimized.

"This was achieved by fabricating thin-film TPV cells with ultra-flat surfaces, and with a metal back reflector," said Dr. Stephen Forrest, professor of electrical and computer engineering, University of Michigan. "The photons above the band-gap of the cell are efficiently absorbed in the micron-thick semiconductor, while those below the band-gap are reflected back to the silicon emitter and recycled."

The team grew thin-film indium gallium arsenide photovoltaic cells on thick semiconductor substrates, and then peeled off the very thin semiconductor active region of the cell and transferred it to a silicon substrate, informing potential interfaces with home battery systems for distributed use.

All these innovations in device design and experimental approach resulted in a novel near-field TPV system that could complement distributed resources in virtual power plants for resilient operations.

"The team has achieved a record ~5 kW/m2 power output, which is an order of magnitude larger than systems previously reported in the literature," said Dr. Pramod Reddy, professor of mechanical engineering, University of Michigan.

Researchers also performed state-of-the-art theoretical calculations to estimate the performance of the photovoltaic cell at each temperature and gap size, informing hybrid designs with backup fuel cell solutions that extend battery life, and showed good agreement between the experiments and computational predictions.

"This current demonstration meets theoretical predictions of radiative heat transfer at the nanoscale, and directly shows the potential for developing future near-field TPV devices for Army applications in power and energy, communication and sensors," said Dr. Pani Varanasi, program manager, DEVCOM ARL that funded this work.

EU Electricity Market Reform advances two-way CfDs, PPAs, and fixed-price tariffs to cut volatility, support renewables and nuclear, stabilize investor revenues, and protect consumers from price spikes across wholesale power markets.

Key Points

An EU plan expanding two-way CfDs, PPAs, and fixed-price contracts to curb price swings and support low-carbon power.

✅ Two-way CfDs return excess revenues to consumers

✅ Boosts PPAs and fixed-price retail options

✅ Targets renewables, nuclear; limits fossil exposure

The European Union wants to expand the use of contracts that pay power plants a fixed price for electricity, a draft proposal showed, as part of an electricity market revamp to shield European consumers from big price swings.

The European Commission pledged last year to reform the EU's electricity market rules, after record-high gas prices, caused by cuts to Russian flows, sent power prices soaring, prompting debates over gas price cap strategies in response.

A draft of the EU executive's proposal, seen by Reuters on Tuesday and due to be published on Mar. 16, steered clear of the deep redesign of the electricity market that some member states have called for, even as nine EU countries opposed sweeping reforms as a fix earlier in the crisis, suggesting instead limited changes to nudge countries towards more predictable, fixed-price power contracts.

If EU countries want to support new investments in wind, solar, geothermal, hydropower and nuclear electricity, for example - a point over which France and Germany have wrestled - they should use a two-way contract for difference (CfD) or an equivalent contract, the draft said.

The aim is to provide a stable revenue stream to investors, and help make consumers' energy bills less volatile, even though rolling back electricity prices is tougher than it appears. Restricting this support to renewable and low-carbon electricity also aims to speed up Europe's shift away from fossil fuels.

Two-way CfDs offer generators a fixed "strike price" for their electricity, regardless of the price in short-term energy markets. If the market price is above the CfD strike price, then the extra revenue the generator receives should be handed out to final electricity consumers, the draft EU document said.

Countries should also make it easier for power buyers to sign power purchase agreements (PPA) - another type of long-term contract to directly buy electricity from a generator.

Governments should also make sure consumers have access to fixed-price electricity contracts - echoing France's new electricity pricing scheme to reassure Brussels - giving them the option to avoid a contract that would expose them to volatile prices swings in energy markets, the draft said.

If European energy prices were to spike to extreme levels again, the Commission suggested allowing national governments to temporarily intervene to fix prices while weighing emergency measures to limit prices where needed, and offer consumers and small businesses a share of their electricity at a lower price.

Hydro-Québec Northeast Clean Energy Transmission delivers surplus hydropower via HVDC interconnections to New York and New England, leveraging long-term contracts and projects like CHPE and NECEC to support carbon-free goals, GHG cuts, and grid reliability.

Key Points

An initiative to expand HVDC links for Quebec hydropower exports, aiding New York and New England decarbonization.

✅ 37,000 MW hydro capacity enables firm, low-carbon exports

✅ Targets NY and NE via CHPE, NECEC, and upgraded interfaces

✅ Backed by long-term PPAs to reduce merchant transmission risk

With roughly 37,000 MW of installed hydro power capacity, Quebec has ample spare capacity that it would like to deliver into Northeastern US markets where ambitious clean energy goals have been announced, but expanding transmission infrastructure is challenging.

Register Now New York recently announced a goal of receiving 100% carbon-free energy by 2040 and the New England states all have ambitious greenhouse gas reduction goals, including a Massachusetts law requiring GHG emissions be 80% below 1990 levels by 2050.

The province-owned company, Hydro Quebec, supplies power to the provinces of Quebec, Ontario and New Brunswick in particular, as well as sending electricity directly into New York and New England. The power transmission interconnections between New York and New England have reached capacity and in order to increase export volumes into the US, "we need to build more transmission infrastructure," Gary Sutherland, relationship manager in business development, recently said during a presentation to reporters in Montreal.

TRANSMISSION OPTIONS

Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, as the province has closed the door on nuclear power and continues to prioritize hydropower, Sutherland said.

The company is looking to sign long-term power supply contracts that could help alleviate some of the investment risk associated with these large infrastructure projects.

"It`s interesting to recall that in the 1980s, two decade-long contracts paved the way for construction of Phase II of the multi-terminal direct-current system (MTDCS), a cross-border line that delivers up to 2,000 MW from northern Quebec to New England," Hydro Quebec spokeswoman Lynn St-Laurent said in an email.

Long-term prices have been persistently low since 2012, following the shale gas boom and the economic decline in 2008-2009, St-Laurent said. "As such, investment risks are too high for merchant transmission projects," she said.

Northeast power market fundamentals "remain strong for long-term contracts," on transmission projects or equipment upgrades that can deliver clean power from Quebec and "help our neighbors reach their ambitious clean energy goals," St-Laurent said.

NEW ENGLAND

In March 2017 an HQ proposal was selected by Massachusetts regulators to supply 9.45 TWh of firm energy to be delivered for 20 years. HQ`s proposal consisted of hydro power supply and possible transmission scenarios developed in conjunction with US partners.

The two leading options include a route through New Hampshire called Northern Pass and New England Clean Energy Connect through Maine.

The New Hampshire Site Evaluation Committee in March 2018 voted unanimously to deny approval of the $1.6 billion Northern Pass Transmission project, which is a joint venture between HQ and Eversource Energy`s transmission business. Eversource has been fighting the decision, with the New Hampshire Supreme Court accepting the company`s appeal of the NHSEC decision in October.

Briefs are being filed and oral arguments are likely to begin late spring or early summer, spokesman William Hinkle said in an email Tuesday.

After the Northern Pass permitting delay, Massachusetts chose the New England Clean Energy Connect project, which is a projected 1,200 MW transmission line, with 1,090 MW contracted to Massachusetts, leaving 110 MW for use on a merchant basis, according to St-Laurent.

NECEC is a joint venture between HQ and Central Maine Power, which is a subsidiary of Avangrid, a company affiliated with Spain`s Iberdrola. The NECEC project has received opposition from some environmental groups and still needs several state and federal permits.

NEW YORK

"The 5% of New York`s load that we furnish year in and year out ... is mostly going into the north of the state, it`s not coming down here," Sutherland said during a discussion at Pace University in New York City in 2017.

One potential project moving through the permitting phase, is the $2.2 billion, 1,000-MW Champlain Hudson Power Express transmission line being pursued by Transmission Developers -- a Blackstone portfolio company -- that would transport power from Quebec to Queens, New York.

Under New York`s proposed Climate Leadership Act which calls for the 100% carbon-free energy goal, renewable generation eligibility would be determined by the Public Service Commission. The PSC did not respond to a question about whether hydro power from Quebec is being considered as a potential option for meeting the state`s clean energy goal.

Geothermal Power Plant Risks include hydrogen sulfide leaks, toxic gases, lava flow hazards, well blowouts, and earthquake-induced releases at sites like PGV and the Geysers, threatening public health, grid reliability, and environmental safety.

Key Points

Geothermal Power Plant Risks include toxic gases, lava impacts, well failures, and induced quakes that threaten health.

✅ Hydrogen sulfide exposure can cause rapid pulmonary edema.

✅ Lava can breach wells, venting toxic gases into communities.

✅ Induced seismicity may disrupt grids near PGV and the Geysers.

If lava reaches Hawaii’s PGV geothermal power plant, it could release of deadly hydrogen sulfide gas. That’s the latest potential danger from the Kilauea volcanic eruption in Hawaii. Residents now fear that lava flow will trigger a meltdown at the Puna Geothermal Venture (PGV) power plant that would release even more toxic gases into the air.

Nobody knows what will happen if lava engulfs the PGV because magma has never engulfed a geothermal power plant, Reuters reported. A geothermal power plant uses steam and gas heated by lava deep in the earth to run turbines that make electricity.

The PGV power plant produces 25% of the power used on Hawaii’s “Big Island.” The plant is considered a source of clean energy because geothermal plants burn no fossil fuels and produce little pollution under normal circumstances, even as nuclear retirements like Three Mile Island reshape low-carbon options.

The Potential Danger from Geothermal Energy

The fear is that the lava would release chemicals used to make electricity at the plant. The PGV has been shut down and authorities moved an estimated 60,000 gallons of flammable liquids away from the facility. They also shut down wells that extract steam and gas used to run the turbines.

Another potential danger is that lava would open the wells and release clouds of toxic gases from them. The wells are typically sealed to prevent the gas from entering the atmosphere.

The most significant threat is hydrogen sulfide, a highly toxic and flammable gas that is colorless. Hydrogen sulfide normally has a rotten egg smell which people might not detect when the air is full of smoke. That means people can breathe hydrogen sulfide in without realizing they have been exposed.

The greatest danger from hydrogen sulfide is pulmonary edema; the accumulation of fluid in the lungs, which causes a person to stop breathing. People have died of pulmonary edema after just a few minutes of exposure to hydrogen sulfide gas. Many victims become unconscious before the gas kills them. Long-term dangers that survivors of pulmonary edema face include brain damage.

Hydrogen sulfide can also cause burns to the skin that are similar to frostbite. Persons exposed to hydrogen sulfide can also suffer from nausea, headaches, severe eye burns, and delirium. Children are more vulnerable to hydrogen sulfide because it is a heavy gas that stays close to the ground.

Geothermal Danger Extends Far Beyond Hawaii

The danger from geothermal energy extends far beyond Hawaii. The world’s largest collection of geothermal power plants is located at the Geysers in California’s Wine Country, and regulatory timelines such as the postponed closure of three Southern California plants can affect planning.

The Geysers field contains 350 steam production wells and 22 power plants in Sonoma, Lake, and Mendocino counties. Disturbingly, the Geysers are located just north of the heavily-populated San Francisco Bay Area and just west of Sacramento, where preemptive electricity shutdowns have been used during extreme fire weather. Problems at the Geysers might lead to significant blackouts because the field supplies around 20% of the green energy used in California.

Another danger from geothermal power is earthquakes because many geothermal power plants inject wastewater into hot rock deep below to produce steam to run turbines, a factor under review as SaskPower explores geothermal in new settings. A geothermal project in Switzerland created Earthquakes by injecting water into the Earth, Zero Hedge reported. A theoretical threat is that quakes caused by injection would cause the release of deadly gases at a geothermal power plant.

The dangers from geothermal power might be much greater than its advocates admit, potentially increasing reliance on natural-gas-based electricity during supply shortfalls.

India spot electricity prices surged on Q3 demand, lifting power tariffs in the spot market as discoms scrambled for supply; Sembcorp SGPL boosted PLF and short-term PPA realizations, benefiting from INR per kWh peaks.

Key Points

India spot electricity prices hit Q3 records amid demand spikes, lifting tariffs and aiding Sembcorp SGPL via PLF gains.

✅ Record 10.6 cents/kWh average; 15-minute peak 20.7 cents/kWh

✅ SGPL shifted output to short-term PPA at 7.3 cents/kWh

✅ PLF ramped above 90%, cutting core losses by 30-40%

Electricity prices in India, now the third-largest electricity producer globally, bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3.

A jolt in Indian spot electricity prices could save Sembcorp Industries' Indian business from further losses, even though demand has occasionally slumped in recent years, UOB Kay Hian said.

The firm said spot electricity prices in India bolted to a record high of 10.6 cents/kWh (INR5.1/kWh) in Q3 and even hit a 15-minute peak of 20.7 cents/kWh (9.9/kWh). The spike was due to a power supply crunch on higher electricity demand from power distribution companies, alongside higher imported coal volumes as domestic supplies shrank.

As an effect, Sembcorp Industries' Sembcorp Gayatri Power Limited's (SGPL) losses of $26m in Q1 and $29m in Q2 could narrow down by as much as 30-40%.

On a net basis, SGPL will recognise a significantly higher electricity tariff in 3Q17. By tactically shutting down its Unit #3 for maintenance, Unit #4 effectively had its generation contracted out at the higher short-term PPA tariff of around 7.3 cents/kWh (Rs3.5/kWh).

SGPL also capitalised on the price spike in 3Q17 as it ramped up its plant load factor (PLF) to more than 90%.

“On the back of this, coupled with the effects of reduced finance costs, we expect SGPL’s 3Q17 quarterly core loss to shrink by 30-40% from previous quarters,” UOB Kay Hian said.

Whilst electricity prices have corrected to 7.1 cents/kWh (INR3.4/kWh), the firm said it could still remain elevated on structural factors, even as coal and electricity shortages ease nationwide.

Sembcorp Industries' India operations brought in a robust performance for Q3. PLF for Thermal Powertech Corporation India Limited (TPCIL) hit 91%, whilst it reached 73% for SGPL, echoing the broader trend of thermal PLF up across the sector.
