Impressive, most impressive. The only things I personally would've done differently would be to give the switchyard a combination of LV, MV, and HV outputs instead of 3x HV, possibly gone for a whole-hog Mark I-I-SUC reactor layout (which would require a frankly terrifying amount of ice generation and even more safeties, IMO), and maybe even incorporated a lapotron charger that moves empty lapotrons from one ender chest and deposits full ones in another for long-distance energy transfer.
