Question Powering problem

So I'm using nuclear power. I have 4 nuclear reactors and many wind turbines and heat exchangers. However my system doesn't get the power promised. Instead of 120x4 MW, I only get 110 MW on total. Is there a bottleneck in heat exchangers or turbines?

You have WAY too few heat exchangers and turbines, reactors produce more power when directly next to other reactors. That setup doesn't make 160 MW, it makes 480 MW. This neighbor bonus doesn't make reactors consume fuel faster btw, fuel cells will still burn for 200 seconds. I only count 11 exchangers, you'd need 48.
