I have a minor suggestion about Kinetic Steam Generator. I think steam should be allowed to flow through it to the next block when steam turbine is not present. So when one turbine fails reactor won't blow up 5 sec later.
Instead of adding another function to it, IC2 should have proper steam (and steam only) pipes that have immense throughput. Also modify the steam generator (aka boiler) to accept fractioned portions of heat, to produce steam/s instead of steam/t
