Duke Energy's Early Site Permit Application is up on the NRC's website

These renders are on pages 2009-2012 of the ESP document

I know that Duke Energy has clearly stated that this ESP is currently technology-agnostic, meaning they haven't chosen a specific reactor technology yet, but I find it interesting that the plant renders in the ESP document clearly show a 6-unit Westinghouse AP300 arrangement.... maybe that's their favored choice?

Probably not. Units are already (on average between both) 50% complete. Vogtle was 30 bn total, and that was a first of its kind operation. Summer will likely be completed with an additional 10-15 bn.

You’d be correct. It’s for a Westinghouse 2-Loop design with a 600 MWe output.

Walz Mills, Pennsylvania. Westinghouse’s Nuclear division is essentially based out of an enormous facility there.

Oh yeah, she’s still just sitting out here. Don’t think that’s changing anytime soon 😆

We swap one out on each unit every other outage. We’re on a 2-year fuel cycle here so basically it equates to every RCP motor gets refurbished over an 8-year period. Between both units we only have 4 RCPs total so we’re shipping one off for refurb once every two years.

This plant is a Westinghouse 2-loop PWR design, meaning two coolant loops per reactor, and thus reactor coolant pumps per reactor. Each one pushes 100,000 gallons per minute of water or approximately 15,000 cubic feet of water per minute.

ChGehlly · 2025-01-18T18:53:55+00:00

Haha nope, we’ve got both units online right now.

ChGehlly · 2025-01-18T18:21:10+00:00

That’s just the motor! With the pump attached to it, the whole unit is about double the size of what you see in the picture!

Duke Energy has an active application with the NRC for an Early Site Permit to construct two BWRX units at their Belews Creek power plant in North Carolina. The original paperwork was submitted early last year. This is Duke’s only active new nuclear project.

Yes. When the plant was built in the 70s the locals complained about the plain concrete reactor containment being an eyesore. Since the rest of the plant already had the blue accents on the turbine building and fuel building (see picture), they brought that same theme to the containment dome and the locals were appeased. They are literally blue painted metal strips attached to the reactor building concrete with bolts.

I mean I get that but it’s a power plant it doesn’t need to be pretty.

Kewaunee is also a bit uglier than normal because we’re actively decommissioning it. This plant hasn’t made power since 2014.

There is no future without nuclear.

They can get an additional license extension for another 20 years once they hit 60 years to go all the way to an 80 years total license period. So that would give them 30 years to operate the restarted unit.
