AUKUS
Aston Martin cars use AMG engines, it doesn't make them Mercedes.
RR got major input from the US on how to improve the design of the PWR3, leading to a 30% in the number of parts, but that doesn't make it an American reactor.
Designed, built and fuelled at Derby so not dependent on the USA for support during it's service life.

UK does it through https://en.wikipedia.org/wiki/Urenco_Group
Also note the US doesn't do nuclear enrichment, they are running from a stockpile of enriched uranium they purchased from Ex USSR / russian decommissioned warheads. At current rate they are expecting to need to restart enrichment in / around 2050. Also US has a license for a SILEX (Separation of Isotopes by Laser EXcitation) that was developed in australia in the late 90's

Urenco currently just produced HEU for civilian use.
The UK has a reported stockpile of 22 tons of HEU, each PWR3 reactor contains around 200Kg of HEU which it burns at the rate of 6.06Kg per year during its working life.
Working on the basis of 4 Dreadnaught, 5 SSNA for Australia and 7 for the UK as Astute replacements will need around 3 tons over the next 30 years. So there is no rush to restart production.

The option for 2 additional Virginia’s is only there in case there are lengthy delays with the SSN-A program & are thus needed to fill the gaps as the Collins class retires. I’m sure that everyone involved is hoping that they are not necessary due to the high additional costs.
The aim is for the RAN to end up with a single fleet of 8 SSN-A’s with the Collins & Virginia’s retired.
I would not be surprised if, assuming funding becomes available, the RN will want more than 7 SSN-A’s as they are finding their current fleet is stretched.

Hopefully, Australia will learn that the smart way to build big things like subs is to always have one on the production line. If they have a 33-year lifespan, we need to be building one every 4 years. When we need a newer model down the track, we modify the existing production line. Not close it down, sack everyone and then go "oh, wow, look how much it's gonna cost us to start a whole new sub-building industry again".

What is the planned size of the Australian production hall?
If it’s similar to that at Barrow it would hold 3 subs in construction - one finishing build, one mid-build and one starting. Assuming a 10-12 year build time that’s one entering service every 5-6 years, which with a 30 year life would be able to maintain a fleet size of 5-6 boats.
An experienced team might get that down to 8 years - the current time to build a Virginia class, rolling one off the stocks every 4 years, which would maintain a fleet of 7-8 boats.
After that you are looking a hall/line able to build 4 at a time.

This pic shows the planned development for the Osborne site. The olive green buildings are existing and the white buildings (& grey paved area) are planned to be built.
The large green shed on the left is where final construction of the Hunter/Type 26 Frigates is underway (capable of two side by side) with further buildings not shown where sections are assembled. The surface ship building area is known as ASC South.
The slightly smaller green building leading to a ship lift is where the, now cancelled, Attack class submarines were to have been built and is the site where the Collins class were originally built and now have their 2 year Full Cycle Docking (every 10 years). This is where ASC North (submarine) starts and will be expanded very significantly.
Those buildings will give a reference for the size of all the planned buildings. It is a massive area of land and, when it’s complete, it will be a very modern, digital, parts manufacturing and submarine assembly complex. The final assembly hall is on the right side adjacent to a very high capacity ship lift. The area is considerably larger than what is in use at Barrow.
The unused section in the middle is the Mutton Cove Conservation Reserve which is off limits to any development.
Future plans for ASC North
Hunter class frigate final assembly hall

I posted some shots of the undeveloped site in #1448 back in October. Its a massive area alright and should allow for an optimised layout .
Its going to be a major employer just building the place.
I know a lot of S Australians are hoping it will restore some engineering jobs that were lost there from the 1970's onwards

I'd be surprised if there aren't some people with Australian accents setting up job shops in Barrow & Derby
More infrastructure in support of Defence members involved with the Submarine and Frigate construction has been announced.

The Royal Navy’s latest Astute Class submarine has been officially named at BAE Systems’ Submarines site in Barrow-in-Furness, Cumbria. Agamemnon - named after the ancient Greek king - is the sixth of seven Astute submarines being built by the Company. Here's the video.

We have China's attention. Let's hope they take it seriously.
AUKUS expansion to 'undermine peace' (ecns.cn)
China is gravely concerned about the potential expansion of the Australia-United Kingdom-United States trilateral security alliance, saying that it would severely undermine peace and stability in the Asia-Pacific region, the Ministry of National Defense said on Thursday.
Wu Qian, the ministry's spokesman, made the remarks at a news conference in Beijing in response to reports that Japan has expressed its intention to join AUKUS and that Canada is considering starting negotiations on joining the security alliance.
"We are open to normal military cooperation between any countries, but we firmly oppose relevant countries forming exclusive groupings, building bilateral or multilateral military alliances targeting China, creating division and stoking bloc confrontation,"
