Working on the point of use design got me thinking about that prior suggestion for rotating reactors. However my goals are different:
Thank you Talon for the excellent reactor planner which allowed me to so easily toy with designs and then collect these numbers.
0) My Metascore = AverageOutput * Eff^3 / (1.5*Iron + 2 * LapisLazui + 4.4 * GlowStoneDust / Eff)
I'll determine runtime by diving the excess heat by the cooling rate; which then determines the number of reactors needed.
I produced these designs, targeting various runtimes using the best design I could deduce within a few moments; it might be possible to get a little more out of them, but the true advantage is in having enough cooling water cells, and enough IHDs touching them, that it's possible to constantly use all the water cells; thus absolute fine-tuning doesn't matter nearly as much as not leaving any hotspots. The formula for evaluating these was deduced after collecting all of the data and adjusted based on my goals to reach the correct range; no design was favored in the weighting.
I noticed that 5 of my designs had issues with isolated cooling water cells. I -believe- I have reviewed and fixed them, but am not entirely sure. In any event, it turns out that the most effective design still is (it simply needed IHDs to replace hull-plating, since the hull-plating would eventually overheat and thus be consumed/suddenly make it explode).
Assumptions: A torch beneath a block providing redstone signal from under the reactor will 'shut down' the reactor. (this allows for 24 blocks of water around the chamber.)
Here's the forumas and table in CSV format, you can edit your weighting and re-sort to see which design works best for /your/ needs.

In case you were wondering how to limit the reactor; it /should/ be possible within a single 16x16x16 chunk (for SMP) even without RedPower 2; however RedPower 2 makes this /FAR/ easier and safer.
If you do choose to set this up, remember to test the output with a torch and confirm it's doing what you want.
T-FlipFlop Design H as a clock divider (double the length).
