Does anybody have a 250% Nuclear power setup that actually works?

Does anybody have a 250% Nuclear power setup that actually works? With "actually works" I mean not getting water starved and running at 98-99%, how can you prevent the unpredictable water physics in the game messing up the flow rate?

After testing the suggestions I have the following feedback, solutions are ranked from leas effective to most:

- Replace all pipes between pipe crosses instead of adding pipecrosses to excising pipes.: - Makes no difference - Intake over the plant no buffer: Doesn't seem to make much of a difference - Buffer inline with plant, connected to the same pipe cross as the plant: Maybe makes a small difference, but not much. - Buffer above the plant intake on the line into the plant: - Slows down the problem quite a bit, goes from maybe 98% efficiency to well above 99. With a large buffer the problem slows down even more, would have to look at it for at least 30 minutes i think for it to idle. - Buffer on pipes from extractors before joining pipes together. Slows down the problem quite a bit, goes from maybe 98% efficiency to well above 99. - MK1 pipes from extractors to the pipe cross in front of plant: Seems to solve the problem 100% and is easy to implement.

Hypothesis: The problem is that for some reason (even if network is completely prefilled) sometimes water flows from one extractor to the other, filling up the extractor to 200 m3, when this happens, the extractor idles for a short while and the system looses water, the more is buffered up in the system the more times this can happen before the plant gets a water problem, but it will eventually happen. This is prevented with mk1 pipes as there is no room for water flowing "backward" to a pump as the whole capacity is used by the pump having a 300m2 flow from its side.

Thanks for all the suggestions, and hopefully this might be useful for someone.

EDIT 2: Tested removing all pipes between pipe crosses and rebuilding instead of putting crosses on excisting pipes, didn't help

EDIT 3: Replacing the pipes from the extractors with mk1 pipes shows promise. Has anyone tried this alone as a solution? Presumably it prevents uneven flow from the 2 extractors.

EDIT 4: Tested with 2 mk2 pipes from extractor up to a fluid buffer above the plant, and then feed the plant from the buffer, this does not seem to solve the problem itself, you still get periodes where the extractors shut off, the buffer delays the problem, but doesn't seem to prevent it. (The delay is very big though, so it helps a lot)
