I posted this on reddit, but I thought I'd also post this here.
Due to me being bored last night(Internet is turned off until tommorow. I'm making this post from my school's internet), I decided to do a bit of testing on reactorcraft pebble beds, made by the amazing Reika. Before I start however, note that most of this is conclusions I have come to that ay very well be incorrect. Anyways, here goes. So first of all, the boilers, pebble bed cores, and exchangers are multiblock in that they connect vertically and share temp and data. A single pebble bed with a single carbon dioxide exchanger and 3 boilers can produce up to roughly 30 MW(not posting RF/t due to me not remembering the conversions). That same pebble bed, with 4 carbon dioxide exchangers and boilers attached to all of them produced 90 MW. But! It took forever to get to the right temperature to produce steam, so not very efficient if you want to keep it turned off when not needed. Stacking this design right ontop of itself(so the blocks combined) cranked out 180-270 MW. But, it worked best with pellets in both cores(which requires roughly 50 pellets.) so efficient? Not at first. But cranks out a lot of power. Can run an extractor at a decent speed with a CVT unit set to speed mode at a 4:1 ratio. You can also do 8:1 and maybe 16:1(but the torque will fluctuate a lot so the extractor may not get the minimum amount required for all stages constantly. Pictures of my setups will come tommorow. Tell me if you have any questions or if I've made any mistakes!
To add on to this post, I asked Reika some questions about the pebble beds so I have some things to add.
1. Number of pellets in the core only affect burn time, not heat
2. If you stack cores on-top of each other, you do in fact need pellets in both cores for max effect.
3. Depleted pellets do not affect efficiency.
4. Adding the cores speed up consumption of pellets.

I'd probably use the hub instead to keep it clean, but yeah that's an option
