The Near-Depleted Uranium Cell is a rarely produced by-product when Uranium Cells decay in the Nuclear Reactor. It can be enriched by creating a Depleted Isotope Cell and then charging it in the Nuclear Reactor, producing a Re-Enriched Uranium Cell. Another way to obtain the Near-Depleted Uranium Cells is to evenly distribute Refined Uranium between 8 Empty Cells. This way, it's possible to increase the energy yield of a single Refined Uranium up to 8-fold. The cell will produce one point of heat each reactor tick but will not interact with any of the adjacent components.
