The power station operates two nuclear reactors in Louisa County, Va. Dominion Energy’s Surry Power Station previously received NRC approval in 2021 to extend its operating license through 2053. Combined, Surry and North Anna generate 40% of Virginia’s electricity and account for about 90% of the carbon-free power in the state.

“For more than 50 years, nuclear power has been the most reliable workhorse of our fleet and the largest source of carbon-free power in Virginia,” said Eric Carr, Dominion Energy’s chief nuclear officer. “North Anna operates around the clock and generates the reliable, clean energy that powers our customers’ homes and businesses every day. With this 20-year extension, our customers can continue counting on North Anna for reliable, carbon-free power for another generation to come.”

Dominion Energy said it is conducting numerous upgrades at the station, including replacing the reactors’ main generators and condensers, refurbishing reactor coolant pumps, and converting instrument and control systems from analog to digital. The company is also implementing 80 enhancements to station procedures, such as additional inspections and equipment testing.

The North Anna units were originally licensed to operate for 40 years in 1978 and 1980. Their licenses were renewed for an additional 20 years in 2003, after a federal review process. Under its current licenses, North Anna reactors 1 and 2 could have operated through 2038 and 2040, respectively. With the renewed licenses, the units can operate through 2058 and 2060, respectively. 

Dominion Energy said it plans to seek recovery of the costs associated with the license extension from the Virginia State Corporation Commission later this year.

The nuclear units at North Anna Power Station are both three-loop Westinghouse pressurized water reactors – capable of providing nearly 2,000 MW at peak capacity, or about 17% of the electricity delivered to Dominion Energy Virginia customers.

Dominion Energy’s affiliated companies also plan to seek NRC approval to extend to 80 years the operating licenses of the V.C. Summer Power Station in South Carolina and Millstone Power Station in Connecticut.

Earlier this year, Dominion Energy Virginia issued a Request for Proposals (RFP) from nuclear technology companies to evaluate the feasibility of developing a small modular reactor (SMR) at the North Anna Power Station. While Dominion stressed the RFP is not a commitment to build this SMR, the company said it is an important first step in evaluating the technology and the North Anna site.

COLUMBIA, S.C. (AP) — The South Carolina Senate on Thursday started its homework assignment of coming up with a comprehensive bill to guide energy policy in a rapidly growing state and amid a quickly changing power- generation world.

The Special Committee on South Carolina’s Energy Future plans several meetings through October. On Thursday, the committee heard from the leaders of the state’s three major utilities. Future meetings will bring in regular ratepayers, environmentalists, business leaders and experts on the latest technology to make electricity,

The Senate took this task upon itself. They put the brakes a massive 80-plus page energy overhaul bill that passed the House in March in less than six weeks, and the bill died at the end of the session.

Many senators said the process earlier this year was rushed. They remembered the last time they trusted an overhaul bill backed by utilities.

State-owned Santee Cooper and private South Carolina Electric & Gas used those rules passed 15 years ago to put ratepayers on the hook for billions of dollars spent on two new nuclear reactors that never generated a watt of power before construction was abandoned because of rising costs.

But those dire memories are being mixed with dire predictions of a state running out of power.

Unusually cold weather on Christmas Eve 2022 along with problems at a generating facility nearly led to rolling blackouts in South Carolina. Demand from advanced manufacturing and data centers is rising. If electric cars grow in popularity, more power is needed. And a state that added 1.3 million people since 2000 has a lot more air conditioners, washing machines and charges for devices, the utility leaders said.

Senators stopped Duke Energy’s president in South Carolina, Mike Callahan, in middle of his presentation after he told them his utility’s most recent predictions for growth in electricity usage over the rest of this decade were eight times more than they were just two years ago.

“Growth is here, and much more is coming. We need clear energy policy to plan for that growth,” Callahan said,

The utility leaders told senators their companies need to know what kind of sources of power — natural gas, solar, nuclear, wind or others — the state wants to emphasize. They would like to have a stable rules from regulators on how they operate.

“A quick no is a lot better to us than a long-term maybe,” Santee Cooper CEO Jimmy Staton said.

Another complicating factor are federal rules that may require utilities to shut down power plants that use coal before there are replacements with different sources online, Staton said.

Others aren’t so sure the state needs a rapid increase in power generation. Environmentalists have suggested the 2022 problems that led to blackouts were made worse because power plants were nowhere near capacity and better cooperation in the grid would allow electricity to get to where its needed easier.

Those less bullish on the overhaul also are urging the state not to lock in on one source of power over another because technology could leave South Carolina with too much power generation in inefficient ways.

There will likely be plenty of discussion of data centers that use a lot of electricity without the number of jobs, property taxes or other benefits a manufacturer provides.

Staton estimated about 70% of Santee Cooper’s increased demand is from data centers.

“We clearly need them. I don’t want to go back in time,” committee chairman Republican Senate Majority Leader Shane Massey said. “What I’m trying to get at is a better understanding, a better handle on how much of the projected growth is based on data centers or on everything else.”

Massey has been hard on Dominion Energy, which bought South Carolina Electric & Gas after the abandoned nuclear project at the V.C. Summer Nuclear Station. But Dominion Energy South Carolina President Keller Kissam said it is important that all options, including a new nuclear plant, remain on the table.

“Everybody thinks if we build anything that we’re going to absolutely repeat what we did with V.C. Summer” Kissam said. “Well, I promise you, that ain’t gonna happen. OK? I’ll pack up and leave.”

Massey said he appreciated Kissam’s candor and felt he was a straight shooter, but there are a lot of other people involved in the failed project who lied and hid problems.

“I can’t put that behind me. And I don’t think a lot of people can put that behind them,” Massey said.

Massey’s goal is to have a bill ready by the time the 2025 session starts in January.

TVA has now approved a total of $350 million in nuclear funding for the SMR project. The federal utility approved an initial $200 million at its February 2022 board meeting.

TVA is among the investors in GE Hitachi’s BWRX-300 SMR, a 300 MWe water-cooled, natural circulation reactor with passive safety systems that leverage the design and licensing basis of GEH’s ESBWR boiling water reactor.

The BWRX-300 leverages a unique combination of existing fuel that is currently used in operating reactors (and does not require HALEU), plant simplifications, proven components and a design based on already licensed reactor technology. 

TVA is currently preparing a construction permit application for a BWRX-300 at the Clinch River Site. The utility is also exploring additional sites in the TVA service area for potential SMR deployments.

“We believe advanced nuclear technologies will play a critical role in our region and nation’s drive toward a clean energy future,” said Jeff Lyash, TVA President and CEO. “Small modular reactors are an energy innovation technology that America must dominate – for our energy security, which is really our national security.”

The TVA Board also took action to accelerate the agency’s deployment of clean technologies, including 10,000 MW of solar by 2035. The Board approved TVA’s FY25 budget, which includes a rate increase to support sustained growth and ongoing construction of nearly 3,500 MW of additional generation.

Utilities everywhere are projecting increased demand, and TVA is no exception. According to TVA, the region’s population is growing three times faster than the national average. To address the need for more electricity, TVA is investing nearly $16 billion through FY27 to build new generation and infrastructure and enhance the reliability of existing assets.

TOKYO (AP) — An attempt to use an extendable robot to remove a fragment of melted fuel from a wrecked reactor at Japan’s tsunami-hit Fukushima Daiichi nuclear power plant was suspended Thursday due to a technical issue.

The collection of a tiny sample of the debris inside the Unit 2 reactor’s primary containment vessel would start the fuel debris removal phase, the most challenging part of the decades-long decommissioning of the plant where three reactors were destroyed in the March 11, 2011, magnitude 9.0 earthquake and tsunami disaster.

The work was stopped when workers noticed that five 1.5-meter (5-foot) pipes used to maneuver the robot were placed in the wrong order and could not be corrected within the time limit for their radiation exposure, the plant operator Tokyo Electric Power Company Holdings said.

The pipes were to be used to push the robot inside and pull it back out when it finished. Once inside the vessel, the robot is operated remotely from a safer location.

The robot can extend up to about 22 meters (72 feet) to reach its target area to collect a fragment from the surface of the melted fuel mound using a device equipped with tongs that hang from the tip of the robot.

The mission to obtain the fragment and return with it is to last two weeks. TEPCO said a new start date is undecided.

“It seems to me a basic mistake,” TEPCO spokesperson Kenichi Takahara said of the pipe setup problem. He said officials are investigating and the retrieval mission will resume only after they find the cause and have preventive measures “so a problem like this should never be repeated.”

TEPCO President Tomoaki Kobayakawa said the priority was safety rather than rushing the process.
The goal of the operation was to bring back less than 3 grams (0.1 ounce) of an estimated 880 tons of fatally radioactive molten fuel. The small sample will provide key data to develop future decommissioning methods and necessary technology and robots, experts say.

Better understanding of the melted fuel debris is key to decommissioning the three wrecked reactors and the entire plant.

The government and TEPCO are sticking to a 30 to 40-year cleanup target set soon after the meltdown, despite criticism it is unrealistic. No specific plans for the full removal of the melted fuel debris or its storage have been decided.

As we’ve reported, OPG is planning to build a total of four SMRs at the Darlington nuclear site and would use GE Hitachi’s BWRX-300 reactor technology. The four units once deployed would produce a total 1,200 MW of electricity.

In its latest filings, the provincial utility said it completed early-phase site preparation work for the first SMR and site clearing activities for the three planned additional SMRs in March 2024. Now, the project has commenced main site preparation activities.

OPG said the project completed the tunnel boring machine launch shaft retaining wall for the condenser cooling water system in June 2024. The company has now begun to drill for the reactor building shaft retaining wall. OPG is also planning for the procurement of long-lead items such as the fabrication of the reactor pressure vessel (RPV).

In October 2022, OPG submitted the License to Construct application to the Canadian Nuclear Safety Commission (CNSC) for the first SMR. In April 2024, Canadian regulators announced that the existing environmental assessment for the project is applicable to the BWRX-300 technology. The CNSC will hold a two-part second public hearing in October 2024 and January 2025 to consider OPG’s application.

Darlington refurbishment update

OPG also provided updates on the Darlington Refurbishment project, which began in 2016 to extend the lives of the station’s four units by at least 30 years. Refurbishment of Unit 2 was completed in June 2020, with Unit 3 completed in July 2023.

Work on Unit 1 began February 2022. In April 2024, OPG completed the lower feeder installation series and the lower body supports installation series for the Unit 1 refurbishment, signaling the end of reassembly. The loading of new fuel into the reactor was completed in May 2024.

The project is currently working to restore the reactor vault, which includes removing the bulkheads to reconnect Unit 1 back to the operating units. Vault restoration is on track for completion in August 2024. OPG said this would represent the completion of construction work and transition of the unit to start-up activities.

OPG said Unit 1 is expected to be returned to service by late 2024, ahead of its original schedule set for the second quarter of 2025.

Unit 4 refurbishment activities are currently in disassembly. The removal of the fuel channel assemblies is expected finished in the third quarter of 2024 with the removal of pressure tubes and calandria tubes. Refurbishment of Unit 4 is scheduled to be complete by the end of 2026.

OPG said the refurbishments of Units 1 and 4 incorporate the learnings from Units 2 and 3. The utility said it continues to assess the impact of the COVID-19 pandemic on the project’s total cost, which is tracking toward its $12.8 billion budget.

In May 2024, OPG applied to renew the operating license for the Darlington GS for a period of 30 years beyond November 2025. The two-part public hearing is scheduled to be held by the CNSC in March 2025 and June 2025.

Westinghouse said this development allows better nuclear fuel efficiency, longer times between reactor refuels and lower operating costs.

U.S. pressurized water reactors currently operate on 18-month fuel cycles, and Westinghouse said this new higher burnup fuel will enable reductions in feed batch size, thereby improving fuel cycle economics. This is the first time nuclear fuel batch reloads in the United States will be able to exceed a burnup limit of 62 GWd/MTU.

“We are very pleased to receive approval from the Nuclear Regulatory Commission for incremental burnup in our nuclear fuel,” said Tarik Choho, Westinghouse President of Nuclear Fuel. “This milestone marks the start of production of nuclear fuel with increased capacity for Pressurized Water Reactors, vastly improving fuel costs for U.S. utility customers.”

The incremental burnup approval also represents a milestone for the Encore Accident Tolerant Fuel Program, an initiative started in 2012 and funded by the Department of Energy, aimed at increasing performance and safety of nuclear reactors in support of U.S. energy security and climate goals.

Of the 650 MW announced during the second quarter of this year, 600 MW were for data center projects. Earlier this year, Oklo signed a pre-agreement with data center colocation company Equinix to provide up to 500 MW of nuclear power. The company has signed an LOI with Wyoming Hyperscale to deliver 100 MW through its data centers.

Another notable agreement could result in Oklo providing 50 MW of power to oil & gas company Diamondback Energy in the Permian Basin in Texas.

The company is working to convert these LOIs into power purchase agreements toward the end of this year and beginning of next, the company said in recent filings to the SEC.

Oklo is developing next-generation nuclear power plants called “powerhouses.”

The company’s Aurora powerhouse design is a fast neutron reactor that would transport heat from the reactor core to a power conversion system and is designed to run on material from used nuclear fuel known as HALEU, or “high assay, low-enriched uranium.” The reactor builds on the Experimental Breeder Reactor-II and space reactor legacy.

The Aurora powerhouse is designed to scale to 15 MW and 50 MW offerings today. Oklo is also evaluating a 100 MW or larger offering that we’re developing.

“We are targeting 15 and 50 megawatt ranges to start because based on the feedback we’ve seen from our customers, that’s a really great size range to be in to meet their needs,” said Oklo Founder and CEO Jacob DeWitte on this week’s earnings call.

DeWitte said the company can scale up with data center projects, which generally don’t come online all at once.

“We can build up to match where our customers are going as they grow their order book and their demand in a phased way, while also building an extra reactor that is providing power on standby for them when they need it,” he said.

Oklo’s first Aurora powerhouse is targeted for deployment in 2027 at the Idaho National Laboratory (INL). Oklo obtained a site use permit from the U.S. Department of Energy (DOE) for the INL site in 2019. The company applied with the U.S. Nuclear Regulatory Commission (NRC) in March 2020 to build and operate the INL reactor. This was the first combined license application ever accepted by the NRC for an advanced non-light water reactor.

In January 2024, the company announced that DOE had reviewed and approved the Safety Design Strategy (SDS) for its Aurora Fuel Fabrication Facility at INL. The Aurora Fuel Fabrication Facility is being designed to demonstrate the reuse of recovered nuclear material to support the reactor demonstration.

Oklo has also formed a non-binding strategic partnership with Atomic Alchemy, which aims to combine Oklo’s expertise in building and operating fast reactors and fuel recycling with Atomic Alchemy’s expertise in isotope production.

The company plans to build its second and third plants in southern Ohio, on land owned by the Southern Ohio Diversification Initiative (SODI). Earlier this year, Oklo entered into land agreements with SODI, which built on the companies’ initial agreement from May 2023.

The Ohio and Idaho projects are for powerhouses at the 15 MW size. But more recently, there has been more interest in the company’s 50 MW offering, Oklo officials said.

The fire, described as small by Georgia Power Co. spokesperson John Kraft, broke out about noon and could have threatened the electrical supply to the heating and cooling system for the control room of one of the complex’s two older nuclear reactors, Vogtle Unit 2.

The fire was put out by plant employees, Georgia Power officials said, and the alert ended just after 2:30 p.m. The cause of the fire hasn’t yet been determined, Kraft said.

Dave Gasperson, a U.S. Nuclear Regulatory Commission spokesperson, said the fire was contained and did not affect any of the plant’s operating systems, and a backup power system remained available for the heating and cooling system. Gasperson said the commission’s onsite inspector monitored the situation and the commission, a federal agency which oversees nuclear power plants, is determining whether additional follow-up inspections are needed.

Officials said the fire caused no injuries and didn’t threaten the safety or health of employees or members of the public. All four of the nuclear reactors onsite continued to produce electricity at full power, Kraft said.

An alert is the second-least serious category of emergency out of four categories designated by the U.S. Nuclear Regulatory Commission, an agency that oversees nuclear power plants. That category could reduce a plant’s level of safety but isn’t supposed to affect the public. The plant returned to normal operations after terminating the alert.

Georgia Power said workers are coordinating recovery with federal, state and local officials. Georgia Power owns the plant along with partners Oglethorpe Power Corp., Municipal Electric Authority of Georgia and Dalton city utilities. It supplies electricity to almost all Georgians, as well as some utilities in Florida and Alabama.

The two older nuclear reactors were completed in 1987 and 1989. If they lose primary electricity from the outside grid, as well as backup electricity from a diesel generator, the reactors can overheat and melt down. A diesel generator was never needed Tuesday, Kraft said.

Vogtle’s two newer nuclear reactors are designed to avoid a meltdown from a power loss. Those reactors were completed this year and are the first new reactors built from scratch in the United States in decades. They cost the owners $31 billion, finishing seven years late and $17 billion over budget. Add in $3.7 billion that original contractor Westinghouse paid Vogtle owners to walk away from construction, and the total nears $35 billion.

Georgia Power is celebrating Generation Appreciation Month, a time to recognize the more than 1,100 team members who “work tirelessly in power plants across state to keep reliable energy flowing to the grid on hot summer days, cold winter mornings and every hour in between.”

“In life, as well as with Georgia Power’s power generation facilities, there is no one-size-fits-all option,” said Rick Anderson, senior vice president and senior production officer for Georgia Power. “From the existing facilities that have powered Georgia for decades, to newer sources of generation such as renewable energy, cleaner natural gas and battery storage, Georgia Power’s diverse generation mix continues to evolve to meet the needs of a growing Georgia. To keep the energy flowing, we need a workforce that is just as advanced and diverse.”

Based on available opportunities, a career in power generation offers many possibilities for those who join the team, Georgia Power said. Career paths exist in the areas of operations, maintenance, electrical, instrumentation, engineering and more. Last year, the company hired over 80 team members across generation facilities and expects the hiring trend to continue in the coming years. Strong training programs exist in Operations, along with apprenticeships in Mechanical and Electrical, which develop experienced journeymen who work safely to keep energy flowing to the grid, 24/7.

Georgia Power also highlighted the “continuous learning” it offers, including the Rockmart training facility where electrical, mechanical, and instrumentation and control technicians hone their skills each year. In 2023, this facility conducted nearly 3,000 hours of both hands-on and classroom instruction. Subject matter experts from both Southern Company and external entities visited to assist in this training program.

Constellation, which operates the largest nuclear fleet in the U.S., is working with data center customers on potential co-location deals, Dominguez said during the company’s second-quarter earnings call this week.

Data centers project to be significant drivers of growth in electricity demand. According to a study recently released by EPRI, data centers could consume up to 9% of U.S. electricity generation by 2030 — more than double the amount currently used.

“The simple fact is that data centers are coming, and they’re essential to America’s national security and economic competitiveness,” said Dominguez.

The rapidly growing data center industry has sparked an active and even divisive discussion among policymakers and stakeholders about how to powering them.

Notably, Exelon and American Electric Power (AEP) are protesting a proposal that would result in the co-location of an Amazon Web Services (AWS) data center at Talen Energy’s Susquehanna nuclear plant in northeast Pennsylvania.

In a filing to the Federal Energy Regulatory Commission (FERC) last month, the parties said the proposed Interconnection Service Agreement (ISA) raises unresolved questions and could result in unfair cost burdens on ratepayers and negatively impact market operations and reliability.

FERC is now seeking more information about the amended ISA. Last week the federal agency called for a technical conference in the fall to discuss co-locating large loads like data centers with generators.

Constellation (a former Exelon entity) believes co-location allows significant new load to be served without requiring expensive system upgrades, especially when grid operators are struggling to integrate new resources faster.

“Friday’s actions at FERC may have slowed things, but ultimately will be constructive in our view,” said Dominguez on the investor call. “We think the benefits [of co-location] are compelling.”

In terms of any co-location deals of its own, Dominguez said Constellation wouldn’t be timebound by any FERC rulemaking on the Talen ISA. He did acknowledge a tightening in the market and more urgency for participants to lock up supply.

“We independently are working on contractual provisions that will allow us to manage whatever outcome comes out of those proceedings,” he said.

Dominguez noted PJM Interconnection’s latest capacity auction, which saw energy prices skyrocket more than 800%. Insufficient future transmission planning, the retirement of fossil-fired generation, long interconnection queues and the implementation of FERC market reforms are all contributing to the hikes.

The auction sends a build signal to generators, but Dominguez said nuclear power specifically could emerge a winner from PJM’s skyrocketing prices. Constellation operates eight nuclear plants (16 reactors) in PJM territory.

“We expect to see higher sustained pricing for capacity to address reliability needs and send more accurate price signals to retain, operate and relicense our plants,” he said.

Meanwhile, PJM utilities have now identified at least 50 GW of expected data center load growth, Dominguez reported.

He said despite disagreement on the vehicle to power data centers, there is a great opportunity for Constellation to work with utilities to bring both grid-connected and co-located projects along.

“We’re still fairly early innings in terms of understanding all of the different use cases and how our resources will interact with the grid,” he said.
