First New US Nuclear Reactor Since 2016 is Now in Operation (eia.gov) 161

U.S. Energy Information Administration, in a press release: A new reactor at Georgia's Vogtle nuclear power plant is now in commercial operation, according to an announcement from Georgia Power, one of the plant's owners. It is the first new nuclear reactor to start up in the United States since the Tennessee Valley Authority's Watts Bar 2 was commissioned in 2016. The new 1,114 megawatt (MW) Unit 3 reactor joins two existing reactors at Plant Vogtle, which is jointly owned by Georgia Power and three other electric utility companies. The plant's first two reactors, with a combined 2,430 MW of nameplate capacity, came online in the late 1980s.

Georgia Power expects another similar-sized fourth reactor, Vogtle Unit 4, to begin operation sometime between November 2023 and March 2024. The two new reactors will make Plant Vogtle the largest nuclear power plant in the country, surpassing the 4,210 MW Palo Verde plant in Arizona. Construction at the two new reactor sites began in 2009. Originally expected to cost $14 billion and begin commercial operation in 2016 (Vogtle 3) and 2017 (Vogtle 4), the project ran into significant construction delays and cost overruns. The total cost of the project is now estimated at more than $30 billion.

      They probably could but then they'd have to decide whether it's the Plant itself that gets to travel in time, all the homes connected to it that do, or perhaps both?

      That'd be an interesting film or TV series actually, reactor mishap causes an entire modern town circa 2023 and their power plant to travel back to the US Mid-West circa 1700s around the time of America's founding.

  • still a long way from 21.1JW
  • that's 2.5x the size of the entire offshore wind project in Rhode Island that just got cancelled but in one single nearly zero emissions plant.
  • Vogtle 3 has been operational for several months.

    was fighting off greenie lawsuits and extrajudicial agitation?

    Pretty fucking dishonest when the supposed environtmental experts telling you nuclear is cost-prohibitive are also the ones driving up the costs of nuclear by agitating against it at the state and municipal level.

    And who benefits? The Saudis, the Chinese, the Russians, the Venezuelans, and everyone else whose sitting on oil and gas and coal and doesn't give a flying fuck about emissions or pollution if it means their electricity stays cheap and their factories keep running while ours close.

    Charge them all as saboteurs and traitors.

    • Near where I live, there is a Native American tribe and their entire tribal income comes from griefer lawsuits. Want to build something? You are going to pay one way or another.

    • "was fighting off greenie lawsuits and extrajudicial agitation?"

      None of it was, dimwit. This additional nuke plant was built alongside two others that have been running for many years.

      Not much, apparently. Hardly surprising, given that this site already had reactors, so all the environmental issues would have been resolved for those.

      From Wikipedia:

      "Two additional units utilizing Westinghouse AP1000 reactors were under construction since 2009, with Unit 3 being completed in July 2023.[9][10][11] This last report blames the latest increase in costs on the contractor not completing work as scheduled. Another complicating factor in the construction process is the bankruptcy of Westinghouse i

    • was fighting off greenie lawsuits and extrajudicial agitation?

      Few. This was an expansion project on an existing site. There's little additional costs from external "agitation". Don't underestimate how much the industry can and has fucked itself.

      - Expertise is non-existent. Most people in the nuclear industry left to go to industries that actually still operated and built things. Many of the expert services companies were bought and sold multiple times and are now in the hands of investment bankers (like Westinghouse was), in the case of the licensor of Vogtle 3 it is

    Many people think that LCOE is good metric. But not all power is equal, what people want is dispatchable power which nuclear provides. Most Nuclear plants have capacity factors or over 90%.
    Wind and Solar may or may not be there when you flick a switch, so you either have to move it through time with a battery, or space with transmission grids. They are intermittent and have low capacity factors.
    Also intermittency creates extra costs, it's like driving a car in a steady state or driving stop/go fashion, stop/go uses way more fuel.
    So firmed Wind and Solar actually means Wind + Solar + battery backup + fossil gas + extra transmission. This is far more expensive.

    And by the way the gas turbines need to be kept idling so they can spool up to take the load if required. This means extra CO2 emissions.
    And your reserve power need to be much larger as all of the solar and wind might disappear for an extended period, this is unlike nuclear or coal where you might lose a reactor.
    Even worse all the gas turbines are fed by common pipelines, when these lack capacity it takes out multiple sources of generation. Nuclear plants go two years without refuelling so they have power on site. This is what happened to the Texas grid.

    • Agree with most of what you said, but the caveat on the nat gas was they needed to put in more heaters. When they reduce the gas pressure, it chills the gas and since there is some moisture in the gas, actually freezes things up. They needed to do more winterizing for the big freeze by adding heaters for the gas depressurizing points. Of course they also needed to winterize the turbines. As I've said frequently, everything failed. Everything. Even the nuke had to go down as the inlet coolant water pipes fro
    • Nuclear plants have multiple vulnerabilities and can shut down for many reasons. Just like the South Texas Project Unit 1, which failed during Snowmageddon. And on top of that, "Approximately 35 GWe of installed thermal generating capacity was not producing electricity".

    • Gas turbines absolutely do NOT need to be kept at idle for peaking. This is why they are used for peaking - because they don't have the multi-hour startup time of thermal power plants. To wit: companies operating natgas peaking plants in "open cycle" sell 10 minute reserve service to grid operators, meaning they can be spun up and synchronized to the grid in under 10 minutes when called upon.

      "Combined Cycle" turbines are more fuel efficient and have a longer startup time, so the play is to start both type

    • See the green line in the graph. That is solar plus wind. There are only 138 MW of solar installed, so it's mostly wind. Wind installed capacity is 2800 MW.

      I posted previously in another article that wind capacity in November was just ove 17% of rating, including a three day run of dead calm.

    Another way to look at it - you need about an acre of solar panels to generate a megawatt of power, conservatively. So this one power plant produces a combined total of over 3,000 acres worth of solar power. That's about a fifth of Manhattan.

    "The new 1,114 megawatt (MW) Unit 3 reactor..." They really couldn't have squeeze 96 more MW out of it so it could be "1.21 jiggawatts"? Missed chances...
  • ...Though, I don't really believe in nuclear accidents--because humans have to work so hard to create a nuclear accident.
  • The owners are projected to pay $31 billion in capital and financing costs. There is no way this nuke plant can generate electricity at competitive prices and that's unfortunate, because nuke plants have to run full time at maximum capacity just to have any hope of earning enough money to pay off the debt.

    This thing will have to be heavily subsidized by Georgia ratepayers.

    "Calculations show Vogtle’s electricity will never be cheaper than other sources Georgia Power could have chosen, even after the fe

    • Carbon taxes will fix the low cost of other sources quickly. Also you might want to look at a map of wind power availability for Georgia, and a cloud cover map. They are not exactly overwhelmed with alternatives.

        Coal, yes, but wind has about the sane g/CO2e per kWh
