I decided to reconstruct and slightly improve the old plan "Nuclear Island (~1.44GW)". How it did, see for yourself on the video "New Nuclear Island (=1.44GW)". The rated power of the NPP is 1.44GW, the maximum critical is 1.44GW, because there are no additional steam turbines on the plan. I simplified fuel supply to reactors.

Write what you would like to add to the plan.
All my videos about tests and not only can be seen on the young Youtube channel: https://www.youtube.com/channel/UC8PzCIkPQl4oGtxTDX66KEw
Tip: if you want to quickly gain temperature in nuclear reactors, just turn off the water supply to the heat exchangers. Do not forget then to return the water supply back. ;)
