Is Nuclear Power in America Reviving - or Flailing? (msn.com) 209

Last week America's energy secretary cheered the startup of a fourth nuclear reactor at a Georgia power plant, calling it "the largest producer of clean energy, and the largest producer of electricity in the United States" after a third reactor was started up there in December.

From the U.S. Energy Department's transcript of the speech: Each year, Units 3 and 4 are going to produce enough clean power to power 1 million homes and businesses, enough energy to power roughly 1 in 4 homes in Georgia. Preventing 10 million metric tons of carbon dioxide pollution annually. That, by the way, is like planting more than 165 million trees every year!

And that's not to mention the historic investments that [electric utility] Southern has made on the safety front, to ensure this facility meets — and exceeds — the highest operating standards in the world....

To reach our goal of net zero by 2050, we have to at least triple our current nuclear capacity in this country. That means we've got to add 200 more gigawatts by 2050. Okay, two down, 198 to go! In building [Unit] 4, we've solved our greatest design challenges. We've stood up entire supply chains.... And so it's time to cash in on our investments by building more. More of these facilities. The Department of Energy's Loan Programs Office stands ready to help, with hundreds of billions of dollars in what we call Title 17 loans... Since the President signed the Inflation Reduction Act and the Bipartisan Infrastructure Law, companies across the nation have announced 29 new or expanded nuclear facilities — across 16 states — representing about 1,600 potential new jobs. And the majority of those projects will expand the domestic uranium production and fuel fabrication, strengthening these critical supply chains...

Bottom line is, in short, we are determined to build a world-class nuclear industry in the United States, and we're putting our money where our mouth is.

America's Energy Secretary told the Washington Post that "Whether it happens through small modular reactors, or AP1000s, or maybe another design out there worthy of consideration, we want to see nuclear built." The Post notes the Energy department gave a $1.5 billion loan to restart a Michigan power plant which was decommissioned in 2022. "It would mark the first time a shuttered U.S. nuclear plant has been reactivated."

"But in this country with 54 nuclear plants across 28 states, restarting existing reactors and delaying their closure is a lot less complicated than building new ones." When the final [Georgia] reactor went online at the end of April, the expansion was seven years behind schedule and nearly $20 billion over budget. It ultimately cost more than twice as much as promised, with ratepayers footing much of the bill through surcharges and rate hikes...

Administration officials say the country has no choice but to make nuclear power a workable option again. The country is fast running short on electricity, demand for power is surging amid a boom in construction of data centers and manufacturing plants, and a neglected power grid is struggling to accommodate enough new wind and solar power to meet the nation's needs...

As the administration frames the narrative of the plant as one of perseverance and innovation that clears a path for restoring U.S. nuclear energy dominance, even some longtime boosters of the industry question whether this country will ever again have a vibrant nuclear energy sector. "It is hard for me to envision state energy regulators signing off on another one of these, given how badly the last ones went," said Matt Bowen, a nuclear scholar at the Center on Global Energy Policy at Columbia University, who was an adviser on nuclear energy issues in the Obama administration.

The article notes there are 19 AP1000 reactors (the design used at the Georgia plant) in development around the world. "None of them are being built in the United States."

        With enough solar panel demands, you also get systems which are more easy to install. The current generation of solar panels is already much easier to deploy than the models 10 or even 20 years ago.

        In Europe, the Balcony Panel is all the rage. Just hang the panels down your balcony, plug the power into one wall outlet, and you are done. For electrical security reason, this is limited to 800 Watt, but still, you get solar power you can install yourself.

      That's great for us rich folks in the suburbs. With huge lots and expansive roofs on which to locate solar. But what about the poor people in cities, resigned to living in commie blocks? A poor ratio of roof to living square footage. And you can't mount solar on walls because, with the demise of interspersed open space (parking lots), walls are in continual shade. Oh yeah. The heat load of high rises is greater (occupied volume vs envelope surface area), so we need that roof for air conditioning equipment.

      • There is something called "community solar", which my utility happens to offer among many others. The panels are in a solar farm, where they are cheap and easy to install vs rooftops. You lease or buy a block of panels. Whatever they produce is subtracted from your residential meter reading.

    $40B comes out to a capital LCOE of $0.16/kWh. In rough terms that means the total wholesale operating cost of energy is in the $0.35-0.40/kWh range. (That assumes that decommissioning cost is equal in dollar terms to the construction cost today, 30 years from now.)

    If you want to make nuclear viable you need to get that capital LCOE down by about 75%. You can save about half that with extremely streamlined permitting process, but the balance of the delta needs to come from construction efficiency improvements. The only way to do that is with less material (less total mass) and tremendous simplification of systems.

    Then you are going to need to improve operations and fuel cost to get them down as well, likely by about 50%.

    This isn't an easy problem to solve, and it is not something that is magically going to happen building another 12 of them. (Using the same construction requirements and assuming that materials and labor rates remain constant you might gain 10-15% efficiency after 12.)

    • We can also try building more than say 2 every 40 years, you have to continue doing something to refine a process. I actually don't think it is a hard process, as you mentioned this is more of an issue of political will and we're only starting getting some of that recently

      • If you are lucky that will reduce construction cost by 10%. You need more fundamental changes. You are plagued by mega-project syndrome with any reactor today-- a Bechtel or whomever cannot pull off 10 at the same time because of the capital risk and duration. You really need modular prefabrication of major components, so that things can be automated more, but radiation poses a few challenges there.

Your exact scenario though is why I really think we should just accept that these things are going to be large public projects, pretty much what TVA does.

    Nuclear power power has high costs (construction, maintenance, fuel, decommissioning). The usual calculations assume at least 30, often 40 or 50 years of service life, generating a net profit after 15 - 30 years (some sources even claim it is never profitable). I don't even want to discuss these numbers, that's not even my point. The main "problem" I see is the price and growth of solar power. In Germany, in several summer months the price of electricity drops below zero during the day (in 2020 it was 300 hours with negative pricing already), since solar systems produce a lot more than is needed, especially at noon. This already has started to affect the nuclear industry in France, who already had to decrease their nuclear energy output during the day. (You can find data about this eg. here https://energy-charts.info/cha... [energy-charts.info] ). That effect wasn't there at all in 2020, but go a few years into the future, the effect will increase and even though it mostly affects the summer months, it will make nuclear power even less attractive in the future. Please note that you can't quickly turn nuclear power plants on and off and when you turn them off, it is costly. On top of that, batteries have become really cheap. I am actually pondering buying a little system myself, it should pay off in a few years AND make me mostly independent in the summer months. Enough storage to get me through the night. When it rains a few days and in winter, I need utilities, sure. What I don't see yet is a nice solution for the winter months, but using nuclear power only in winter is not attractive commercially. So, building new plants feels quite risky to me.
