nuclear reactor (MK I-O) generating 120 EU/t

Both of these are low-efficiency generators -- you're only getting 10 EU/t from each lone uranium cell, and 20 EU/t from the two linked ones in the first nuke. The problem with that is that you're massively wasting uranium, which has the potential to give you up to 50 EU/t from a single cell (surrounded by four others), just to keep from dealing with the cooling requirements (130 heat generated per cycle).

It's much better to build multiple high-efficiency reactors than one low-efficiency one, since your uranium gets closer to producing those ideal amounts of power from each cell. Look at Rick's thread of excellent reactor designs, for instance -- two of his 70 EU/t reactors will output more than either of your reactors, and will only need six uranium cells in total, where you're using 10 for each!

Considering the one-time cost of building the reactor is amortized over time and approaches zero, the only real cost of nuclear engineering is how much uranium you put in over time, and with Rick's designs you're getting more power for less uranium.

I measure fail level of reactor designs like this by amount of heating plates that can be removed, without touching anything else, so reactor will still works exactly same.
8 of 17. Ouch. not a record by far, though.

Strange, I was able to find 18 HDs and remove 9 of them. http://www.talonfiremage.pwp.b…g13nbkhtogcnma96xe75d569s

I also keep posting this one. It has highest effective EU i have seen on Mark I and is in my opinion brilliant design, if uranium is not the problem.

you could fill it up with coolant cells
