Is there a cost effective way to move that heat to where it could be used?

Nuclear reactors can produce very high temperatures, but in most reactors the heat is moved to turbines using water. Are there ways to move the heat at the high temperatures required to melt steel? (AFAIK, even molten salt is too cold.)

People have been talking about this since at least the 1970s, but no existing reactors have high enough temperatures. There are various concepts on paper that could do it.
