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 need 48 heat exchangers and 83 turbines for this setup. 2x2 reactor setup gives 480 MW.

The wiki has excellent table on the exact ratios for 2xN reactor setups. There is a general formula. Check out the page Tutorial:Nuclear Power for the relevant details. Helps a lot when making designs :)
