AkhkharuXul : yes. Mine can do that configuration, as well as simply fuel rods covering all but the top row.
This configuration is an example : http://test.vendaria.net/index…UXUIUIUXUIUIUXXXXXXXXXXXX
So I can also do lesser cases like the one you showed. Note that the breeding configuration you showed gives less than half the power of just filling the reactor with uranium. And with enough massfabs that have an uninterrupted feed of scrap, you can massfab fresh uranium directly with 37.5% of the energy the reactor produces.
The difference between mine and rick are :
1. I use 2 filters to pull empty buckets out, increasing the rate I can pump full buckets in.
2. I use a timer instead of a sequencer for control of key steps because a timer is much faster.
3. I use 4 deployers for filling buckets instead of just 1 (to be certain that the bottleneck is elsewhere)
4. I recirculate filled buckets that pop out the top of the reactor directly back in.
This makes my reactor larger and more complex than Rick's. But my peak power is higher (640 EU/tick) and efficiency slightly better (4.27)
