Plan Yuan Class Aip & Kilo Submarine Thread

Are there any good guesses how much power such a system should generate ?

If I'm not wrong, "normal" AIP systems generate a few hundred KW of power.
A reactor for a "normal" SSN would generate at least 5MW of usable power (shaft/electric) which would be >15MW thermal (for a rather "underpowered" SSN).

I guess a "nuclear AIP" should fit the following demands:
- enough power to be worth the trouble (at least as much power as a "normal AIP")
- significantly smaller and cheaper than "real nuclear propulsion"
- lower maintenance needs than "real nuclear propulsion", perhaps some way to change the whole "power pack" at once after opening a big hatch
- no need for "nuclear engineers" in the crew (or at least significantly reduced compared to "real nuclear propulsion")

Could something like a 500KW (electric) reactor (perhaps 2MW thermal) fit these requirements ?
Maybe 600kW?

There is an estimate of 38KW required for a stationary Yuan.

Then there is the smaller Gotland submarine which has 150KW of Stirling Engines for a sustained speed of 5knots.
And the Type-212 has a total of 600KW of fuel cells. It did a 2800km journey in 2weeks at 4-5knots as well.
Plus the Soviets tested 600KW VAU-6 auxiliary reactors on their diesel-electric submarines.

With later and later pictures, I see less and less of the square sailed Yuans. Either the number of the curved sail Yuans are increasing --- no way to track the new builds --- or older ones are being refitted to the new form. Or both is happening.

Was it stretched for movie purposes? Or was the boat the navy lent out for filming stretched to begin with?
