1010 Powah!
Wolfe knew that he didn't need to generate an actual nuclear reaction inside the reactor, all he had to do was generate intense heat, and the coolant circulating as steam through the turbines. The whole reactor complex was self-contained, while the coolant lines ran in a large loop underground to cool the fluid naturally as it returned.
Wolfe began building the first of the arrays in front of him, where he could see what he was doing, though it was just simple air and gravity magic to make the steam carry more force as it hit the turbine. Then he added layers of gravity magic for the turbine to spin more freely, and electromagnetism to the actual generator coils.
That was enough to set up the output side of the reactor, and Wolfe nodded in satisfaction as he laid the spell over the Reactor Two complex.
