Hamann Construction, an El Cajon, Calif.-based general contractor, recently achieved LEED Gold certification from the U.S. Green Building Council on a 134,946 sq. ft. build-to-suit cold storage facility occupied by Innovative Cold Storage Enterprises Inc. (ICE).

The property, called ICE II, is situated on 6.78 acres in the Otay Mesa submarket of San Diego, Calif.

Used as a refrigerated warehousing and storage facility for pre-packaged food items, which are stored at 10 degrees Fahrenheit, the facility has a height of 60 feet, can hold 29,000 pallets and has a storage capacity of 7.5 million cubic feet.

"As the owner, general contractor and LEED administrator on ICE II, Hamann Construction is proud to have accomplished LEED Gold Certification after four full years of the design process and 14 months of construction," said Gregg Hamann, vice president and CFO of Hamann Cos. in a statement. "We not only value green building from an environmental standpoint, we value it from an economical one as well."

Energy efficient measures for ICE II provide an annual savings of more than 3.4 million kilowatt-hours and are estimated to save in annual energy costs of more than $408,000 at current prices, according to Hamann.

The interior of the freezer was designed with extremely narrow aisle racking to maximize the use of space. Additionally, efficient goods storage and retrieval is achieved through the use of radio frequency technology and electric forklifts that recharge their batteries with energy generated by the weight of the product being lowered from the racks.

Other energy-efficient features include day-lighting and high-efficiency controllable lighting, a cool roof, increased ventilation, carbon dioxide monitors, reflective concrete, and water re-use and conservation measures, among others. There is also approximately 5,000 sq. ft. of office space.

"Overall this facility is 62% more energy efficient than a baseline cold storage facility," says Phoebe Hamann Jones, a LEED accredited professional with Hamann Construction. "It is able to hold four times more product than ICE's original facility, however, it requires only half as much energy to operate."

Hamann and San Diego Gas & Electric (SDG&E) jointly developed a one megawatt solar photovoltaic system on the roof. The 504-kilowatt Hamann-owned system will produce approximately 883,008 kilowatt-hours per year, providing approximately 36% of the facility's energy requirements. A second 504-kilowatt system, also on ICE II's roof, is owned by SDG&E and will provide clean, locally generated power to the community.

The systems will reduce demand on the grid during peak energy times. Between the entire solar roof system and 10, one-kilowatt wind turbines mounted on the parapet, 73% of the facility's energy will be provided through renewable energy sources.

Each year the energy savings from the combined energy-efficient measures and renewable energy production will prevent 3,683 metric tons of carbon dioxide from entering the atmosphere, according to Hamann.

Tories 'taking the heart out of Manitoba Hydro' by promoting subsidiaries, scrapping low-cost pledges: NDP

Manitoba Hydro Privatization Debate centers on subsidiaries, Crown corporation governance, clean energy priorities, and electricity rates, as board terms shift oversight and transparency, sparking concerns about sell-offs and government control.

 

Key Points

A dispute over Hydro's governance, subsidiaries, electricity rates, and clean energy amid fears of partial privatization.

✅ Rewritten terms allow subsidiaries and shift board duties.

✅ Low rates and clean energy mandates softened in guidance.

✅ Govt cites Hydro Act; NDP warns of sell-off risks.

 

The board of Manitoba Hydro is being reminded it can divvy up some of the utility's work to subsidiaries — which the NDP is decrying as a step toward privatization. 

A sentence seemingly granting the board permission to create subsidiaries was included in the board's new terms of reference, which the NDP raised during question period Wednesday. 

The document also eliminated references asking Manitoba Hydro to keep electricity rates low, even as rate hike hearings proceed, and supply power in an environmentally-friendly fashion.

NDP raises spectre of Manitoba Hydro's privatization with new CEO
"They're essentially taking the heart out of Manitoba Hydro," NDP leader Wab Kinew said.

Cheap, clean energy is the basis by which the Crown corporation was formed, even as scaled-back rate increases are planned for next year, he said. 

"That's the whole reason we created this utility in the first place."

Another addition to the board's guidelines include stating the corporation is responsible to the government minister, who must be "proactively informed" when significant issues arise. 

The provincial government, however, says the rewritten terms of reference was the directive of the Manitoba Hydro board and not itself.

CBC's requests to the government for an interview were directed to Manitoba Hydro.

In an interview, Manitoba Hydro spokesperson Scott Powell said the energy utility has undergone no legislative changes, and is still governed by the Manitoba Hydro Act. 

The terms of reference were altered to align the board's duties with the new act overseeing Crown corporations, Powell said.

"Whether you have one or two words different in the terms of reference, the essence of the company hasn't changed."

While the new terms of reference no longer instructs the corporation to ensure an "environmentally responsible supply of energy for Manitobans," it encourages the board to "promote economy and efficiency in all phases of power generation and distribution."

On the cost to ratepayers, the updated directions asks the utility to deliver "safe, reliable energy services at a fair price," a standard clarified by a recent appeal court ruling on First Nations rates, but the board is not specifically instructed with keeping electricity rates low. 

Kinew contends the added sentence on subsidiaries permits Hydro to be broken off and sold for parts, although the terms of reference does not specify if any subsidiary would be wholly owned by Hydro or contracted to a private company.

Powell said Manitoba Hydro has been permitted to create subsidiaries since 1997, and nothing has changed since.

Kinew warned about Hydro's privatization last week when Jay Grewal was announced as Hydro's incoming CEO and president.

She was employed with B.C. Hydro when then-premier Gordon Campbell — hired by the Manitoba government to investigate costly overruns on two electricity megaprojects — sold off segments of the utility.

She then became managing director of Accenture, a global management consulting firm, which acquired several B.C. Hydro departments.

During question period Wednesday, Pallister disputed that Manitoba Hydro is bound to be sold.

He slammed the NDP's "Americanization strategy" of producing more electricity than it is capable of selling, which has saddled ratepayers with billions in debt and prompted proposed 2.5% annual increases in coming years. 

The makeup of the Hydro board has undergone a complete turnover in under a year, a contrast to Ontario's Hydro One shakeup vow during that period.

Nine of the 10 members resigned en masse this March over an impasse with the Pallister government. The lone holdover, Cliff Graydon, was dismissed from his post last month after the Progressive Conservatives removed him from caucus.

Salmon and electricity at center of Columbia River treaty negotiations

Columbia River Treaty Negotiations involve Canada-U.S. talks on B.C. dams, flood control, hydropower sharing, and downstream benefits, prioritizing ecosystem health, First Nations rights, and salmon restoration while balancing affordable electricity for northwest consumers.

 

Key Points

Talks to update flood control, hydropower, and ecosystem terms for fair benefits to B.C. and U.S. communities.

✅ Public consultations across B.C.'s Columbia Basin

✅ First Nations priorities include salmon restoration

✅ U.S. seeks cheaper power; B.C. defends downstream benefits

 

With talks underway between Canada and the U.S. on the future of the Columbia River Treaty, the B.C. New Democrats have launched public consultations in the region most affected by the high-stakes negotiation.

“We want to ensure Columbia basin communities are consulted, kept informed and have their voices heard,” said provincial cabinet minister Katrine Conroy via a press release announcing meetings this month in Castlegar, Golden, Revelstoke, Nakusp, Nelson and other communities.

As well as having cabinet responsibility for the talks, Conroy’s Kootenay West riding includes several places that were inundated under the terms of the 1964 flood control and power generation treaty.

“We will continue to work closely with First Nations affected by the treaty, to ensure Indigenous interests are reflected in the negotiations,” she added by way of consolation to Indigenous people who’ve been excluded from the negotiating teams on both sides of the border.

The stakes are also significant for the province as a whole. The basics of the treaty saw B.C. build dams to store water on this side of the border, easing the flood risk in the U.S. and allowing the flow to be evened out through the year. In exchange, B.C. was entitled to a share of the additional hydro power that could be generated in dams on the U.S. side.

B.C.’s sale of those downstream benefits to the U.S has poured almost $1.4 billion into provincial coffers over the past 10 years, albeit at a declining rate these days amid scrutiny from a regulator report on BC Hydro that raised concerns, because of depressed prices for cross-border electricity sales.

Politicians on the U.S. side have long sought to reopen the treaty, believing there was now a case for reducing B.C.’s entitlement.

They did not get across the threshold under President Barack Obama.

Then, last fall his successor Donald Trump served notice of intent, initiating the formal negotiations that commenced with a two day session last week in Washington, D.C. The next round is set for mid-August in B.C.

American objectives in the talks include “continued, careful management of flood risk; ensuring a reliable and economical power supply; and better addressing ecosystem concerns,” with recognition of recent BC Hydro demand declines during the pandemic.

“Economical power supply,” being a diplomatic euphemism for “cheaper electricity for consumers in the northwest states,” achievable by clawing back most of B.C.’s treaty entitlement.

On taking office last summer, the NDP inherited a 14-point statement of principles setting out B.C. hopes for negotiations to “continue the treaty” while “seeking improvements within the existing framework” of the 54-year-old agreement.

The New Democrats have endorsed those principles in a spirit of bipartisanship, even as Manitoba Hydro governance disputes play out elsewhere in Canada.

“Those principles were developed with consultation from throughout the region,” as Conroy advised the legislature this spring. “So I was involved, as well, in the process and knew what the issues were, right as they would come up.”

The New Democrats did chose to put additional emphasis on some concerns.

“There is an increase in discussion with Canada and First Nations on the return of salmon to the river,” she advised the house, recalling how construction of the enormous Grand Coulee Dam on the U.S. side in the 1930s wiped out salmon runs on the upper Columbia River.

“There was no consideration then for how incredibly important salmon was, especially to the First Nations people in our region. We have an advisory table that is made up of Indigenous representation from our region, and also we are discussing with Canada that we need to see if there’s feasibility here.”

As to feasibility, the obstacles to salmon migration in the upper reaches of the Columbia include the 168-metre high Grand Coulee and the 72-metre Chief Joseph dams on the U.S. side, plus the Keenleyside (52 metres), Revelstoke (175 metres) and Mica (240 metres) dams on the Canadian side.

Still, says Conroy “the First Nations from Canada and the tribes from the United States, have been working on scientific and technical documents and research to see if, first of all, the salmon can come up, how they can come up, and what the things are that have to be done to ensure that happens.”

The New Democrats also put more emphasis on preserving the ecosystem, aligning with clean-energy efforts with First Nations that support regional sustainability.

“I know that certainly didn’t happen in 1964, but that is something that’s very much on the minds of people in the Columbia basin,” said Conroy. “If we are going to tweak the treaty, what can we do to make sure the voices of the basin are heard and that things that were under no consideration in the ’60s are now a topic for consideration?”

With those new considerations, there’s still the status quo concern of preserving the downstream benefits as a trade off for the flooding and other impacts on this side of the border.

The B.C. position on that score is the same under the New Democrats as it was under the Liberals, despite a B.C. auditor general report on deferred BC Hydro costs.

“The level of benefits to B.C., which is currently solely in the form of the (electricity) entitlement, does not account for the full range of benefits in the U.S. or the impacts in B.C.,” says the statement of principle.

“All downstream U.S. benefits such as flood risk management, hydropower, ecosystems, water supply (including municipal, industrial and agricultural uses), recreation, navigation and other related benefits should be accounted for and such value created should be shared equitably between the two countries.”

No surprise if the Americans do not see it the same way.  But that is a topic for another day.

Rooftop Solar Grids

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

 

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

 

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

Nuclear helps Belgium increase electricity exports in 2019

Belgium Energy Mix 2019 shows strong nuclear output, rising offshore wind, net electricity exports, and robust interconnections, per Elia, as the nuclear phaseout drives 3.9GW new capacity needs after improved reactor availability.

 

Key Points

High nuclear share, offshore wind, net exports, interconnections; 3.9GW capacity needed amid nuclear phaseout.

✅ Nuclear supplied 48.8% of generation in 2019.

✅ Net exporter: 1.8 TWh, aided by interconnections.

✅ Elia projects 3.9GW new capacity for phaseout.

 

Belgium's electricity transmission system operator, Elia, said that the major trends in 2019 were a steady increase in (mainly offshore) renewable power generation, illustrated by EU wind and solar records across the bloc, better availability of nuclear-generating facilities and an increase in electricity exports.

In 2019, 48.8% of the power generated in Belgium came from nuclear plants. This was in line with the total for 2017 (50%) and significantly more than in 2018 (31.2%) when several reactors were unavailable amid stunted hydro and nuclear output in Europe as well.

Belgium exported more electricity in 2019, as neighbors like Germany saw renewables overtake coal and nuclear generation, with net exports of 1.8TWh (2.1% of the energy mix), in contrast to 2018 when Belgium imported 17.5TWh (20%).

Elia said this “should be viewed in its wider context, of declining nuclear capacity in Europe and regional market shifts, against the backdrop of an increasingly Europeanised market, and can be explained primarily by the good availability of Belgium's generating facilities (especially its nuclear power stations).”

The development of interconnections was also a key factor in the circulation of these electricity flows, as seen with Irish grid price spikes highlighting regional stress, Elia noted.

“Belgium had not been a net exporter of electricity for almost 10 years, the last time being in 2009 and 2010, when total net exports represented 2.8% and 0.2% respectively of Belgium’s energy mix,” it said.

Belgian has seven nuclear reactors – three at Tihange near Liege and four at Doel near Antwerp – and, regionally, nuclear-powered France faces outage risks that influence cross-border reliability.

In 2003, Belgium decided to phase out nuclear power and passed a law to that effect, with neighbors like Germany navigating a balancing act during their energy transition, which was reaffirmed in 2015 and 2018.

A commission appointed to assess the impact of the nuclear phaseout is scheduled to be completed in 2025 but has yet to report any findings.

Elia estimates that some 3.9GW of new power generating capacity will be needed to compensate for Belgium's nuclear phaseout.

Calgary electricity retailer urges government to scrap overhaul of power market

Alberta Capacity Market Overhaul faces scrutiny over electricity costs, reliability targets, investor certainty, and AESO design, as UCP reviews NDP reforms, renewables integration, and deregulated energy-only alternatives impacting generators, ratepayers, and future power price volatility.

 

Key Points

A shift paying generators for capacity and energy to improve reliability; critics warn of higher electricity costs.

✅ UCP reviewing NDP plan and subsidies amid market uncertainty

✅ AESO cites reliability needs as coal retires, renewables grow

✅ Critics predict overprocurement and premature launch cost spikes

 

Jason Kenney's government is facing renewed pressure to cancel a massive overhaul of Alberta's power market that one player says will needlessly spike costs by hundreds of millions of dollars, amid an electricity sector in profound change today.

Nick Clark, who owns the Calgary-based electricity retailer Spot Power, has sent the Alberta government an open letter urging it to walk away from the electricity market changes proposed by the former NDP government.

"How can you encourage new industry to open up when one of their raw material costs will increase so dramatically?" Clark said. "The capacity market will add more costs to the consumer and it will be a spiral downwards."

But NDP Leader Rachel Notley, whose government ushered in the changes, said fears over dramatic cost increases are unfounded.

"There are some players within the current electricity regime who have a vested interest in maintaining the current situation," Notley said

Kenney's UCP vowed during the recent election to review the current and proposed electricity market options, as the electricity market heads for a reshuffle, with plans to report on its findings within 90 days.

The party also promised to scrap subsidies for renewable power, while ensuring "a market-based electricity system" that emphasizes competition in Alberta's electricity market for consumers.

The New Democrats had opted to scrap the current deregulated power market — in place since the Klein era — after phasing out coal-fired generation and ushering in new renewable power as part of changes in how Alberta produces and pays for electricity under their climate change strategy.

The Alberta Electric System Operator, which oversees the grid, says the province will need new sources of electricity to replace shuttered coal plants and backstop wind and solar generators, while meeting new consumer demand.

After consulting with power companies and investors, the AESO concluded in late 2016 the electricity market couldn't attract enough investment to build the needed power generation under the current model.

The AESO said at the time investors were concerned their revenues would be uncertain once new plants are running. It recommended what's known as a capacity market, which compensates power generators for having the ability to produce electricity, even when they're not producing it.

In other words, producers would collect revenue for selling electricity into the grid and, separately, for having the capacity to produce power as a backstop, ensuring the lights stay on. Power generators would use this second source of income to help cover plant construction costs.

Clark said the complex system introduces unnecessary costs, which he believes would hurt consumers in the end. He said what's preventing investment in the power market is uncertainty over how the market will be structured in the future.

"What investors need to see in this market is price certainty, regulatory ease, and where the money they're putting into the marketplace is not at risk," he said.

"They can risk their own money, but if in fact the government comes in and changes the policy as it was doing, then money stayed away from the province."

Notley said a capacity market would not increase power bills but would avoid big price swings, with protections like a consumer price cap on power bills also debated, while bringing greener sources of energy into Alberta's grid.

"Moving back to the [deregulated] energy-only market would make a lot of money for a few people, and put consumers, both industrial and residential, at great risk."

Clark disagrees, citing Enmax's recent submissions to the Alberta Utilities Commission, in which the utility argues the proposed design of the capacity market is flawed.

In its submissions to the commission, which is considering the future of Alberta's power market, Enmax says the proposed system would overestimate the amount of generation capacity the province will need in the future. It says the calculation could result in Alberta procuring too much capacity.

The City of Calgary-owned utility says this could drive up costs by anywhere from $147 million to $849 million a year. It says a more conservative calculation of future electricity demand could avoid the extra expense.

An analysis by a Calgary energy consulting firm suggests a different feature of the proposed power market overhaul could also lead to a massive spike in costs.

EDC Associates, hired by the Consumers' Coalition of Alberta, argues the proposal to launch the new system in November 2021 may be premature, because it could bring in additional supplies of electricity before they're needed.

The consultant's report, also filed with the Alberta Utilities Commission, estimates the early launch date could require customers to pay 40 per cent more for electricity amid rising electricity prices in the province — potentially an extra $1.4 billion — in 2021/22.

"The target implementation date is politically driven by the previous government," said Duane Reid-Carlson, president of EDC Associates.

Reid-Carlson recommends delaying the launch date by several years and making another tweak: reducing the proposed target for system reliability, which would scale back the amount of power generation needed to backstop renewable sources.

"You could get a result in the capacity market that would give a similar cost to consumers that the [deregulated] energy-only market design would have done otherwise," he said.

"You could have a better risk profile associated with the capacity market that would serve consumers better through lower cost, lower price volatility, and it would serve generators better by giving them better access to capital at lower costs."

The UCP government did not respond to a request for comment.

Can Europe's atomic reactors bridge the gap to an emissions-free future?

EU Nuclear Reactor Life Extension focuses on energy security, carbon-free electricity, and safety as ageing reactors face gas shortages, high power prices, and regulatory approvals across the UK and EU amid winter supply risks.

 

Key Points

EU Nuclear Reactor Life Extension is the policy to keep ageing reactors safely generating affordable, low-carbon power.

✅ Extends reactor operation via inspections and component upgrades

✅ Addresses gas shortages, price volatility, and winter supply risks

✅ Requires national regulator approval and cost-benefit analysis

 

Shaken by the loss of Russian natural gas since the invasion of Ukraine, European countries are questioning whether they can extend the lives of their ageing nuclear reactors to maintain the supply of affordable, carbon-free electricity needed for net-zero across the bloc — but national regulators, companies and governments disagree on how long the atomic plants can be safely kept running.

Europe avoided large-scale blackouts last winter despite losing its largest supplier of natural gas, and as Germany temporarily extended nuclear operations to bolster stability, but industry is still grappling with high electricity prices and concerns about supply.

Given warnings from the International Energy Agency that the coming winters will be particularly at risk from a global gas shortage, governments have turned their attention to another major energy source — even as some officials argue nuclear would do little to solve the gas issue in the near term — that would exacerbate the problem if it too is disrupted: Europe’s ageing fleet of nuclear power plants.

Nuclear accounts for nearly 10% of energy consumed in the European Union, with transport, industry, heating and cooling traditionally relying on coal, oil and natural gas.

Historically nuclear has provided about a quarter of EU electricity and 15% of British power, even as Germany shut down its last three nuclear plants recently, underscoring diverging national paths.

Taken together, the UK and EU have 109 nuclear reactors running, even as Europe is losing nuclear power in several markets, most of which were built in the 1970s and 1980s and were commissioned to last about 30 years.

That means 95 of those reactors — nearly 90% of the fleet — have passed or are nearing the end of their original lifespan, igniting debates over how long they can safely continue to be granted operating extensions, with some arguing it remains a needed nuclear option for climate goals despite age-related concerns.

Regulations differ across borders, with some countries such as Germany turning its back on nuclear despite an ongoing energy crisis, but life extension discussions are usually a once-a-decade affair involving physical inspections, cost/benefit estimates for replacing major worn-out parts, legislative amendments, and approval from the national nuclear safety authority.
