Hmm; this might work - the black hole could be surrounded by a small fusion disk, generating enough energy to run the civilisation, the suprashell and the refrigeration system. All waste heat from these three systems could be dumped back into the black hole. Would this work, or am I dreaming? The minimum temperature of the whole system would be the black body temperature of the black hole itself, but since it is surrounded by a large radiating suprashell, that temperature could be lowered to CMBR values or beyond.
As for stabilising a wormhole, send heat one way and matter the other. A few more gigatons of iron wouldn't make much difference to the inhabited end of the wormhole, even if it isn't cooled to 2.7K and dumped outside, yet the energy equivalent would support the present day human civilization for a billion years.
