An aging nuclear reactor that produces the bulk of the global supply of medical isotopes will be out of service for at least three months as officials try to find out what is wrong and how to fix it.

Atomic Energy of Canada Ltd. extended an unexpected shutdown of the nuclear reactor at Chalk River, Ont., after discovering a heavy water leak on May 15.

"Sophisticated diagnostic procedures are required to determine the exact nature and extent of the repairs before returning the NRU reactor safely to service," Bill Pilkington, chief nuclear officer at AECL, said in a statement. "Based on our preliminary findings to date, we now believe that the NRU reactor will be out of service for at least three months."

Natural Resources Minister Lisa Raitt said she is still talking to other countries that produce medical isotopes to figure out how to fill the gap in supply.

"I continue to lead productive discussions with my counterparts in other isotope-producing countries that have some ability to assist with this supply issue," Raitt said in a statement. "These countries all have different constraints and capacity that we are working through, but we will continue using all resources available to us to manage this shortfall."

Federal Health Minister Leona Aglukkaq said she is working with her provincial and territorial counterparts to see how hospitals can best cope with the shortage of the radioisotopes needed for crucial diagnostic tests. Isotopes are used in some cancer treatments.

"The real problem is that those other reactors don't have the excess capacity that (Chalk River) has," said Robert Atcher, president of the Society of Nuclear Medicine.

Atcher told Reuters there are also fears AECL will find other corrosion problems in the reactor that will lengthen the shutdown or force a permanent closure.

"To say we're concerned is an understatement," Atcher said.

Hugh MacDiarmid, AECL's chief executive, said: "Until all investigations are completed, it is premature at this point to set a definitive timeline for the return to service of the NRU reactor."

Here's what we know about the mistaken Pickering nuclear alert one week later

Pickering Nuclear Alert Error prompts Ontario investigation into the Alert Ready emergency alert system, Pelmorex safeguards, and public response at Pickering Nuclear Generating Station, including potassium iodide orders and geo-targeted notification issues.

 

Key Points

A mistaken Ontario emergency alert about the Pickering plant, now under probe for human error and system safeguards.

✅ Investigation led by Emergency Management Ontario

✅ Alert Ready and Pelmorex safeguards under review

✅ KI pill demand surged; geo-targeting questioned

 

A number of questions still remain a week after an emergency alert was mistakenly sent out to people across Ontario warning of an unspecified incident at the Pickering Nuclear Generating Station. 

The province’s solicitor general has stepped in and says an investigation into the incident should be completed fairly quickly according to the minister.

However, the nuclear scare has still left residents on edge with tens of thousands of people ordering potassium iodide, or KI, pills that protect the body from radioactive elements in the days following the incident.

Here’s what we know and still don’t know about the mistaken Pickering nuclear plant alert:

Who sent the alert?

According to the Alert Ready Emergency Alert System website, the agency works with several federal, provincial and territorial emergency management officials, Environment and Climate Change Canada and Pelmorex, a broadcasting industry and wireless service provider, to send the alerts.

Martin Belanger, the director of public alerting for Pelmorex, a company that operates the alert system, said there are a number of safeguards built in, including having two separate platforms for training and live alerts.

"The software has some steps and some features built in to minimize that risk and to make sure that users will be able to know whether or not they're sending an alert through the... training platform or whether they're accessing the live system in the case of a real emergency," he said.

Only authorized users have access to the system and the province manages that, Belanger said. Once in the live system, features make the user aware of which platform they are using, with various prompts and messages requiring the user's confirmation. There is a final step that also requires the user to confirm their intent of issuing an alert to cellphones, radio and TVs, Belanger said.

Last Sunday, a follow-up alert was sent to cellphones nearly two hours after the original notification, and during separate service disruptions such as a power outage in London residents also sought timely information.

What has the investigation revealed?

It’s still unclear as to how exactly the alert was sent in error, but Solicitor General Sylvia Jones has tapped the Chief of Emergency Management Ontario to investigate.

"It's very important for me, for the people of Ontario, to know exactly what happened on Sunday morning," Jones said.

Jones said initial observations suggest human error was responsible for the alert that was sent out during routine tests of the emergency alert.

“I want to know what happened and equally important, I want some recommendations on insurances and changes we can make to the system to make sure it doesn't happen again,” Jones said.

Jones said she expects the results of the probe to be made public.

Can you unsubscribe from emergency alerts?

It’s not possible to opt out of receiving the alerts, according to the Alert Ready Emergency Alert System website, and Ontario utilities warn about scams to help customers distinguish official notices.

“Given the importance of warning Canadians of imminent threats to the safety of life and property, the CRTC requires wireless service providers to distribute alerts on all compatible wireless devices connected to an LTE network in the target area,” the website reads.

The agency explains that unlike radio and TV broadcasting, the wireless public alerting system is geo-targeted and is specific to the a “limited area of coverage”, and examples like an Alberta grid alert have highlighted how jurisdictions tailor notices for their systems.

“As a result, if an emergency alert reaches your wireless device, you are located in an area where there is an imminent danger.”

The Pickering alert, however, was received by people from as far as Ottawa to Windsor.

Is the Pickering Nuclear Generating Station closing?

The Pickering nuclear plant has been operating since 1971, and had been scheduled to be decommissioned this year, but the former Liberal government -- and the current Progressive Conservative government -- committed to keeping it open until 2024. Decommissioning is now set to start in 2028.

It operates six CANDU reactors, and in contingency planning operators have considered locking down key staff to maintain reliability, generates 14 per cent of Ontario's electricity and is responsible for 4,500 jobs across the region, according to OPG, while utilities such as Hydro One's relief programs have supported customers during broader crises.

What should I do if I receive an emergency alert?

Alert Ready says that if you received an alert on your wireless device it’s important to take action “safely”.

“Stop what you are doing when it is safe to do so and read the emergency alert,” the agency says on their website.

“Alerting authorities will include within the emergency alert the information you need and guidance for any action you are required to take, and insights from U.S. grid pandemic response underscore how critical infrastructure plans intersect with public safety.”

“This could include but is not limited to: limit unnecessary travel, evacuate the areas, seek shelter, etc.”

The wording of last Sunday's alert caused much initial confusion, warning residents within 10 kilometres of the plant of "an incident," though there was no "abnormal" release of radioactivity and residents didn't need to take protective steps, but emergency crews were responding.

“In the event of a real emergency, the wording would be different,” Jones said.

5,000 homes would be switched to geothermal energy free of charge

Manitoba NDP Geothermal Conversion Program offers full-cost heat pump installation for 5,000 homes, lowering electricity bills, funding contractor training and rebates, and cutting greenhouse gas emissions via geothermal energy administered by Efficiency Manitoba.

 

Key Points

A plan funding 5,000 home heat pump conversions to cut electricity bills, reduce emissions, and expand installer capacity.

✅ Covers equipment and installation for 5,000 homes

✅ Cuts electricity bills up to 50% vs electric heat

✅ Administered by Efficiency Manitoba; trains contractors

 

An NDP government would cover the entire cost for 5,000 families to switch their homes to geothermal energy, New Democrats have promised.

If elected on Oct. 3, the NDP will pay for the equipment and installation of new geothermal systems at 5,000 homes, St. James candidate Adrien Sala announced outside a St. Boniface home that previously made the switch. 

The homes that switch to geothermal energy could save as much as 50 per cent on their electricity bills, Sala said.

"It will save you money, it will grow our economy and it will reduce greenhouse gas emissions. And I think we can safely call that a win, win, win," Sala said.

Geothermal energy is derived from heat that is generated within the Earth.

The NDP said each conversion to geothermal heating and cooling would cost an estimated $26,000, and comes as new turbine investments advance in Manitoba, and it would take four years to complete all 5,000 conversions.

The program would be administered through Efficiency Manitoba, the Crown corporation responsible for conserving energy, as Manitoba Hydro's new president navigates changes at the utility. The NDP estimates it will cost $32.5 million annually over the four years, at a time of red ink at Manitoba Hydro as new power generation needs loom. Some of that money would support the training of more contractors who could install geothermal systems.


Subsidies get low pickup: NDP
Sala wouldn't say Wednesday which homeowners or types of homes would be eligible.

He said the NDP's plan would be a first in Canada, even as Ontario's energy plan seeks to address growing demand elsewhere.

"What we've seen elsewhere is where other jurisdictions have used a strict subsidy model, where they try to reduce the cost of geothermal, and while Ontario reviews a halt to natural gas generation to cut emissions, approaches differ across provinces. We really haven't seen a lot of uptake in those other jurisdictions," Sala said.

"This is an attempt at dealing with one of those key barriers for homeowners."

Efficiency Manitoba runs a subsidy program for geothermal energy through ground source heat pumps, supporting using more electricity for heat across the province, valued at up to $2.50 per square foot. It is estimated a 1,600 sq. ft. home switching from an electric furnace to geothermal will receive a rebate of around $4,000 and save around $900 annually on their electricity bills, the Crown corporation said.anitoba homeProgressive Conservative spokesperson Shannon Martin questioned how NDP Leader Wab Kinew can afford his party's numerous election promises.

"He will have no choice but to raise taxes, and history shows the NDP will raise them all," said Martin, the McPhillips MLA who isn't seeking re-election.

Wednesday's announcement was the first for the NDP in which Kinew wasn't present. The party has criticized the Progressive Conservatives for leader Heather Stefanson showing up for only a few announcements a week.

Sala said Kinew was busy preparing for the debate later in the day.

"This stuff is near and dear to Wab's heart, and frankly, I think he's probably hurting that he's not here with us right now."

More Polar Vortex 2021 Fallout (and Texas Two-Step): Monitor For ERCOT Identifies Improper Payments For Ancillary Services

ERCOT Ancillary Services Clawback and VOLL Pricing summarize PUCT and IMM actions on load shed, real-time pricing adders, clawbacks, and settlement corrections after the 2021 winter storm in the Texas power grid market.

 

Key Points

Policies addressing clawbacks for unprovided AS and correcting VOLL-based price adders after load shed ended in ERCOT.

✅ PUCT ordered clawbacks for ancillary services not delivered.

✅ IMM urged price correction after firm load shed ceased.

✅ ERCOT's VOLL adder raised costs by $16B during 32 hours.

 

Potomac Economics, the Independent Market Monitor (IMM) for the Electric Reliability Council of Texas (ERCOT), filed a report with the Public Utility Commission of Texas (PUCT) that certain payments were made by ERCOT for Ancillary Services (AS) that were not provided, even as ERCOT later issued a winter reliability RFP to procure capacity during subsequent seasons.

According to the IMM (emphasis added):

There were a number of instances during the operating days outlined above in which AS was not provided in real time because of forced outages or derations. For market participants that are not able to meet their AS responsibility, typically the ERCOT operator marks the short amount in the software. This causes the AS responsibility to be effectively removed and the day-ahead AS payment to be clawed back in settlement. However, the ERCOT operators did not complete this task during the winter event, echoing issues like the Ontario IESO phantom demand that cost customers millions, and therefore the "failure to provide" settlements were not invoked in real time.

Removing the operator intervention step and automating the "failure to provide" settlement was contemplated in NPRR947: Clarification to Ancillary Service Supply Responsibility Definition and Improvements to Determining and Charging for Ancillary Service Failed Quantities; however, the NPRR was withdrawn in August 2020 amid ongoing market reform discussions because of the system cost, some complexities related to AS trades, and the implementation of real-time co-optimization.

Invoking the "failure to provide" settlement for all AS that market participants failed to provide during the operating days outlined above will produce market outcomes and settlements consistent with underlying market principles. In this case, the principle is that market participants should not be paid for services that they do not provide, even as a separate ruling found power plants exempt from providing electricity in emergencies under Texas law, underscoring the distinction between obligations and settlements. Whether ERCOT marked the short amount in real-time or not should not affect the settlement of these ancillary services.

On March 3, 2021, the PUCT ordered (a related press release is here) that:

ERCOT shall claw back all payments for ancillary service that were made to an entity that did not provide its required ancillary service during real time on ERCOT operating days starting February 14, 2021 and ending on February 19,2021.

On March 4, 2021, the IMM filed another report and recommended that:

the [PUCT] direct ERCOT to correct the real-time prices from 0:00 February 18,2021, to 09:00 February 19, 2021, to remove the inappropriate pricing intervention that occurred during that time period.

The IMM approvingly noted the PUCT's February 15, 2021 order, which mandated that real-time energy prices reflect firm load shed by setting prices at the value of lost load (VOLL).1

According to the IMM (emphasis added):

This is essential in an energy-only market, like ERCOT's, where the Texas power grid faces recurring crisis risks, because it provides efficient economic signals to increase the electric generation needed to restore the load and service it reliably over the long term.

Conversely, it is equally important that prices not reflect VOLL when the system is not in shortage and load is being served, and experiences in capacity markets show auction payouts can fall sharply under different conditions. The Commission recognized this principle in its Order, expressly stating it is only ERCOT's out-of-market shedding firm load that is required to be reflected in prices. Unfortunately, ERCOT exceeded the mandate of the Commission by continuing to set process at VOLL long after it ceased the firm load shed.

ERCOT recalled the last of the firm load shed instructions at 23:55 on February 17, 2021. Therefore, in order to comply with the Commission Order, the pricing intervention that raised prices to VOLL should have ended immediately at that time. However, ERCOT continued to hold prices at VOLL by inflating the Real-Time On-Line Reliability Deployment Price Adder for an additional 32 hours through the morning of February 19. This decision resulted in $16 billion in additional costs to ERCOT's market, prompting legislative bailout proposals in Austin, of which roughly $1.5 billion was uplifted to load-serving entities to provide make-whole payments to generators for energy that was not needed or produced.

However, at its March 5, 2021, open meeting (related discussion begins around minute 20), although the PUCT acknowledged the "good points" raised by the IMM, the PUCT was not willing to retrospectively adjust its real-time pricing for this period out of concerns that some related transactions (ICE futures and others) may have already settled and for unintended consequences of such retroactive adjustments.

National Grid to lose Great Britain electricity role to independent operator

UK Future System Operator to replace National Grid as ESO, enabling smart grid reform, impartial system planning, vehicle-to-grid, long duration storage, and data-driven oversight to meet net zero and cut consumer energy costs.

 

Key Points

The UK Future System Operator is an independent ESO and planner, steering net zero with impartial data and smart grid coordination.

✅ Replaces National Grid ESO with independent system operator

✅ Enables smart grid, vehicle-to-grid, and long-duration storage

✅ Supports net zero, lower bills, and impartial system planning

 

The government plans to strip National Grid of its role keeping Great Britain’s lights on as part of a proposed “revolution’” in the electricity network driven by smart digital grid technologies.

The FTSE 100 company has played a role in managing the energy system of England, Scotland and Wales, including efforts such as a subsea power link that brings renewable power from Scotland to England (Northern Ireland has its own network). It is the electricity system operator, balancing supply and demand to ensure the electricity supply. But it will lose its place at the heart of the industry after government officials put forward plans to replace it with an independent “future system operator”.

The new system controller would help steer the country towards its climate targets, at the lowest cost to energy bill payers, by providing impartial data and advice after an overhaul of the rules governing the energy system to make it “fit for the future”.

The plans are part of a string of new proposals to help connect millions of electric cars, smart appliances and other green technologies to the energy system, and to fast-track grid connections nationwide, which government officials believe could help to save £10bn a year by 2050, and create up to 10,000 jobs for electricians, data scientists and engineers.

The new regulations aim to make it easier for electric cars to export electricity from their batteries back on to the power grid or to homes when needed. They could also help large-scale and long-duration batteries play a role in storing renewable energy, supported by infrastructure such as a 2GW substation helping integrate supply, so that it is available when solar and wind power generation levels are low.

Anne-Marie Trevelyan, the energy and climate change minister, said the rules would allow households to “take control of their energy use and save money” while helping to make sure there is clean electricity available “when and where it’s needed”.

She added: “We need to ensure our energy system can cope with the demands of the future. Smart technologies will help us to tackle climate change while making sure that the lights stay on and bills stay low.”

The energy regulator, Ofgem, raised concerns earlier this year that National Grid would face a “conflict of interest” in providing advice on the future electricity system because it also owns energy networks that stand to benefit financially from future investment plans. It called for a new independent operator to take its place.

Jonathan Brearley, Ofgem’s chief executive, said the UK requires a “revolution” in how and when it uses electricity, including demand shifts during self-isolation to help meet its climate targets and added that the government’s plans for a new digital energy system were “essential” to meeting this goal “while keeping energy bills affordable for everyone”.

A National Grid spokesperson said the company would “work closely” with the government and Ofgem on the role of a future system operator, as well as “the most appropriate ownership model and any future related sale”.

The division has earned National Grid, which has addressed cybersecurity fears in supplier choices, an average of £199m a year over the last five years, or 1.3% of the group’s total revenues, which are split between the UK – where it operates high-voltage transmission lines in England and Wales, and the country’s gas system – and its growing energy supply business in the US, aligned with investment in a smarter electricity infrastructure in the US to modernize grids.

Indian government takes steps to get nuclear back on track

India Nuclear Generation Shortfall highlights missed five-year plan targets due to uranium fuel scarcity, commissioning delays at Kudankulam, PFBR slippage, and PHWR equipment bottlenecks under IAEA safeguards and domestic supply constraints.

 

Key Points

A gap between planned and actual nuclear output due to fuel shortages, reactor delays, and first-of-a-kind hurdles.

✅ Fuel scarcity pre-2009-10 constrained unsafeguarded reactors.

✅ Kudankulam delays from protests, litigation, and remobilisation.

✅ FOAK PHWR equipment bottlenecks and PFBR slippage.

 

A lack of available domestically produced nuclear fuel and delays in constructing and commissioning nuclear power plants, including first-of-a-kind plants and the Prototype Fast Breeder Reactor (PFBR), meant that India failed to meet its nuclear generation targets under the governmental plans over the decade to 2017, even as global project milestones were being recorded elsewhere.

India's nuclear generation target under its 11th five-year plan, covering the period 2007-2012, was 163,395 million units (MUs) and the 12th five-year Plan (2012-17) was 241,748 MUs, Minister of state for the Department of Atomic Energy and the Prime Minister's Office Jitendra Singh told parliament on 6 February. Actual nuclear generation in those periods was 109,642 MUs and 183,488 MUs respectively, Singh said in a written answer to questions in the Lok Sabah.

Singh attributed the shortfall in generation to a lack of availability of the necessary quantities of domestically produced fuel during the three years before 2009-2010; delays to the commissioning of two 1000 MWe nuclear power plants at Kudankulam due to local protests and legal challenges; and delays in the completion of two indigenously designed pressurised heavy water reactors and the PFBR.

Kudankulam 1 and 2 are VVER-1000 pressurised water reactors (PWRs) supplied by Russia's Atomstroyexport under a Russian-financed contract. The units were built by Nuclear Power Corporation of India Ltd (NPCIL) and were commissioned and are operated by NPCIL under International Atomic Energy Agency (IAEA) safeguards, with supervision from Russian specialists, while China's nuclear program advanced on a steady development track in the same period. Construction of the units - the first PWRs to enter operation in India - began in 2002.

Singh said local protests resulted in the halt of commissioning work at Kudankulam for nine months from September 2011 to March 2012, when he said project commissioning had been at its peak. As a consequence, additional time was needed to remobilise the workforce and contractors, he said. Litigation by anti-nuclear groups, and compliance with supreme court directives, impacted commissioning in 2013, he said. Unit 1 entered commercial operation in December 2014 and unit 2 in April 2017.

Delays in the manufacture and supply by domestic industry of critical equipment for first-of-a-kind 700 MWe pressurised heavy water reactors -  Kakrapar units 3 and 4, and Rajasthan units 7 and 8 - has led to delays in the completion of those units, the minister said, as well as noting the delay in completion of the PFBR, which is being built at Kalpakkam by Bhavini. In answer to a separate question, Singh said the PFBR is in an "advance stage of integrated commissioning" and is "expected to approach first criticality by the year 2020."

Eight of India's operating nuclear power plants are not under IAEA safeguards and can therefore only use indigenously-sourced uranium. The other 14 units operate under IAEA safeguards and can use imported uranium. The Indian government has taken several measures to secure fuel supplies for reactors in operation and under construction, amid coal supply rationing pressures elsewhere in the power sector, concluding fuel supply contracts with several countries for existing and future reactors under IAEA Safeguards and by "augmentation" of fuel supplies from domestic sources, Singh said.

Kakrapar 3 and 4, with Kakrapar 3 criticality already reported, and Rajasthan 7 and 8 are all currently expected to enter service in 2022, according to World Nuclear Association information.

 

Joint venture discussions

In February 2016 the government amended the Atomic Energy Act to allow NPCIL to form joint venture companies with other public sector undertakings (PSUs) for involvement in nuclear power generation and possibly other aspects of the fuel cycle, reflecting green industrial strategies shaping future reactor waves globally. In answer to another question, Singh confirmed that NPCIL has entered into joint ventures with NTPC Limited (National Thermal Power Corporation, India's largest power company) and Indian Oil Corporation Limited. Two joint venture companies - Anushakti Vidhyut Nigam Limited and NPCIL-Indian Oil Nuclear Energy Corporation Limited - have been incorporated, and discussions on possible projects to be set up by the joint venture companies are in progress.

An exploratory discussion had also been held with Oil & Natural Gas Corporation, Singh said. Indian Railways - which has in the past been identified as a potential joint venture partner for NPCIL - had "conveyed that they were not contemplating entering into an MoU for setting up of nuclear power plants," Singh said.

Perry presses ahead on advanced nuclear reactors

Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.

 

Key Points

Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.

✅ DOE test facility at Idaho National Laboratory

✅ Small modular reactors with passive safety systems

✅ University simulators train next-gen nuclear operators

 

Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.

The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.

“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.

With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.

A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.

“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.

The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.

On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.

The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.

NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”
