You have to apply a direct redstone signal to the reactor, I'm pretty certain that was stated in that thread
EDIT: It was even bolded, just skimming through it, it's hard to miss
QuoteBe advised that, for your own security, Uranium cells do only do 'something' when the reactor is receiving a direct redstone signal.

"integrated heat dispenser" are the old version of nuclear reactors, so no you cannot craft those anymore in the new version.
