First nuclear reactors since 1970s approved in US

The US Nuclear Regulatory Commission has approved the first nuclear reactors to be built in the country since 1978.

The commission voted 4-1 in favour of Southern Co building two nuclear reactors at an existing Georgia plant.

But Chairman Gregory Jaczko voted against, expressing concern that the licence was being approved "as if Fukushima never happened".

The reactors are expected to cost $14bn (?8.8bn) and could begin operating as early as 2016 or 2017.

No reactors have been approved for construction since a year before the accident at Three Mile Island, a nuclear power plant in Pennsylvania, in 1979.

'Binding commitment'

Safety concerns around nuclear power have risen following a meltdown at Japan's Fukushima power plant in March 2011 after an earthquake and tsunami damaged safety features.

In the wake of the Japanese disaster the commission launched a review into whether existing and new US reactors could withstand natural disasters like earthquakes and floods.

Mr Jaczko said he believes approving the reactors "requires some type of binding commitment" that safety enhancements planned from the review would be in place before the reactors opened.

Southern's project is considered a test of whether the industry can avoid costly delays that plagued previous reactors.

The Obama administration has offered Southern and its partners $8.3bn in federal loan guarantees, helping lowering financing costs.

The reactor design, approved separately in December, will also be used by utility companies in Florida and South Carolina currently in the approval process.

"as if Fukushima never happened"

Saying this is as dumb as saying that it's a shame that airplanes are still being produced after 9/11

I wouldn't call coal safe, those plants can put out a fair bit of radioactive material.

On top of the massive amount of any other kind of pollution that's guaranteed with burning fossil fuels. Nuclear only poses a safety risk in the case of a leak or other disaster which is actually pretty rare, just big news when it does happen. Fossil fuels on the other hand pollute and cause air quality issues all day every day.

At least someone in the US has some sense.

Meanwhile in the EU, "Green people" are more and more successful at shutting down existing nuclear power plants. In a few years time we will probably be burning wood again to heat ourselves and use candles for lighting.

More likely in a few years we'll be buying energy from countries that produce it with nuclear plants.

This is already happening in Italy where nuclear energy has been banned in the 80's after chernobyl disaster. Nowadays we buy energy from France. Energy produced in nuclear plants located near italian borders. :rolleyes:

If a Coal plant explodes, then the surround area is usable again within a relatively short time compared to using Nuclear.

I'm not against Nuclear, but i'm just point that fact out. Modern nuclear designs are far safer than they used to be. (Y)

Most modern reactor designs are not capable of doing a Cherynobl or Fukushima - they passively safe themselves.

Then there is my favorite: liquid salt thoroum reactors; the fuel is molten naturally, so there is no structure to damage. This plus the benefits of the thorium fuel cycle.

I watched a TED video about this. It sounds highly promising.

If that's the design I'm thinking of, then it's naturally self moderating. As it heats up the fuel expands, extending outside the main reactor core, slowing down the reaction and letting it cool down and contract again.

Awesome design, but at the same time it increases the risk of processing accidents while decreasing the risk of operating accidents (Since the fuel is liquid, it's easy to spill, vs. a solid rod or such)

Edit: The CANDU design is similar in how it handles that situation, the fuel rods are mounted horizontally so if they start overheating and melting, they bend out of shape and slow down the reaction (And the CANDU design can run on just about anything, natural uranium, spent fuel from other reactors, dismantled nuclear warheads, thorium, etc.)

    • Are they marketed as an entry into astronomy or astrophotography? I do astrophotography. With big rigs, lots of computers, cables and headaches. I love it. And by learning this ridiculously complex hobby, I’ve learned about the objects I’m shooting. Astronomy followed from photography.
    • Microsoft confirms Recycle Bin bug across all versions of Windows by Usama Jawad A couple of days ago, we reported that the latest Patch Tuesday update has seemingly resulted in a lot of issues for many users, including OneDrive and Dropbox access problems, BitLocker recovery lockouts, and BSODs. Although Microsoft is yet to acknowledge these bugs, it has confirmed another, relatively smaller issue across all supported versions of Windows. In an update on its Windows Release Health Dashboard, Microsoft has confirmed that after installing June's Patch Tuesday update (KB5094126), you'll experience unexpected behavior when leveraging Recycle Bin. Basically, when you attempt to delete an item from the Recycle Bin, the confirm dialog will show you the internal file name of that content rather than the actual name. For example, the file may be named abc.png, but the confirm dialog will ask if you're sure that you want to permanently delete $Rxxxxx.png from the Recycle Bin. This is pretty much it for the scope of the bug itself; it just displays the wrong name in the confirm dialog. The correct name will be shown in the list view of the Recycle Bin and if you restore the file, it will return with the correct name as well. This issue affects pretty much all supported versions of Windows client and server, including: Client: Windows 11, version 26H1; Windows 11, version 25H2; Windows 11, version 24H2; Windows 11, version 23H2; Windows 10, version 22H2; Windows 10 Enterprise LTSC 2021; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSB 2016 Server: Windows Server 2025; Windows Server 2022; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012 As things currently stand, Microsoft is working on a concrete solution that will be released in a "future" Windows update. It remains to be seen if the firm will wait till the next Patch Tuesday or roll out an out-of-band (OOB) fix. The good news is that commercial customers can deploy a workaround right now, but they will have to reach out to Microsoft Support for Business for additional details.
    • They said by this time everyone will have flying cars. WELL...
    • A study by physicist Henry Tye of Cornell University suggests that the universe may not expand forever. Instead, it could eventually stop expanding, begin contracting and end in a "Big Crunch" roughly 20 billion years from now. Maybe not as we now know that time can flow backwards.
    • Of course. Simply reverse the polarity.
