What is the most efficient setup for a 6 Chambered Reactor, and have it NEVER overheat.
Ideally I would not want the cooling components to meltdown either.
Please note the setup is for a SIX CHAMBERED REACTOR not six reactors.
The design shown below produces a signifigant 320 eu\t but this is the design given at the wiki. I'm sure there must be a better one.
Note that efficiency (EU/rod) and throughout (EU/t) are not related. A high throughput reactor is not necessarily efficient.
This answer considers efficiency as total EU/rod, which is what the reactor planner app defines as efficiency.
One very efficient design is this:
It has an efficiency factor of 7, or 14mEU / rod (throughput: 140 EU/t). (*)
In general, reflectors increase efficiency, cells increase throughout. Both increase heat.
(*) It does require 16 iridium, which is a pain to get
Note that this is can be further simplified in terms of resources required as follows:
