Study reveals single-step strategy for recycling used nuclear fuel

A typical nuclear reactor uses only a small fraction of its fuel rod to produce power before the energy-generating reaction naturally terminates. What is left behind is an assortment of radioactive elements, including unused ...

Opening access to explore the synthetic chemistry of neptunium

Leftovers from nuclear reactors contain the element neptunium. To safely store the waste, scientists need to know more about how to control neptunium's chemistry. Knowing the stability of different oxidation states is central ...

Researchers discover new way of 'locking up' radioactive material

Researchers at The University of Manchester have discovered that an iron oxide mineral, hematite, reacts with radioactive neptunium to 'lock it up' within its structure. This could have profound implications for the environmental ...

Encouraging minerals to capture troubling radionuclides

Associated with contamination in certain spots around the world, pentavalent neptunium does not always behave the same as its stand-in when moving through the soil, according to scientists at University of Notre Dame and ...
