Lithium has potential value as a heat-transfer fluid for high power-density nuclear reactors. The lithium-7 isotope, the more common stable isotope, has a low nuclear cross section (that is, it absorbs neutrons very poorly) and thus has potential as a primary coolant for nuclear reactors in which coolant temperatures above about 800 °C (1,500 ...
