Big Reactors not producing Heat

[Chief_Sunboyz]

So I recently created a 7x7x7 passively cooled (cryotheum) reactor for a map I'm making and it worked great! So I world edit copy/pasted another one next to the original. Problem is, that copy/pasted one doesn't produce any heat or energy. I have a ME System set to automatically input yellorium & output cyanite. When I turn on the reactor, the core has 100% fuel, all temps are 20 Degrees, and no energy is being created.
I have 5 fuel rods and no coolant access block or whatever it's called.
Here is what my reactor layout looks like:

X = Reactor Casing
C = Coolant
R = Fuel Rod

X X X X X X X
X C C C C C X
X C C R C C X
X C R R R C X
X C C R C C X
X C C C C C X
X X X X X X X

Any feedback is appreciated,
Thanks,
~~Chief
