This is a list of my designed reactors. Not the best but they work for me.
Currently im planning on bulding the Mk II-5 EC
Mark V EA Breeder
Running Time: 55 seconds unheated/32 seconds heated
Cooling time: 70 Minutes unheated/3 minutes heated
Power: 720 EU/t (144,000,000/cycle)
Efficiency: 4.22 (Class A)
Outside Cooling?: Yes (20 water blocks)
Notes:
Isotope cells can be removed augmenting the reactor to a Mark V EA that has the following edited specs,
Running time: 1 minute
Cooling Time: 80 minutes
Heated level is 6,000 heat (141 buckets of lava).\
Inner cooling cells can be replaced with isotope cells for more breeding of uranium. Please note that this decreases running time as well as cooling time and in some cases may become impossible to run.
Mark II - 5 EC
Running Time: 5 cycles
Cooling time: 22 Minutes
Power: 120 EU/t (24,000,000/cycle)
Efficiency: 2.00 (Class C)
Outside Cooling?: Yes (20 water blocks)
Notes:
Placing a Ice Block in the empty slot will augment the reactor to a Mark II-E-SUC EC and change the following stats,
Running time: 33 cycles
Cooling Time: 4 minutes
Mark I - O ED
A 6 chamber reactor with no excess heat buildup. Capable of running for a indefinent amount of time. Relies on outside cooling (water). Outputs 100 EU/t and has a efficiency of 1.67.
Mark I - O ED
Same as above except it has no excess chambers (pure reactor) and only outputs 50 EU/t. Good for all those new to nuclear. Only requires 16 blocks of water to cool compared to the above 20.
