due to its long half-life (4.5 Ga), the behavior of uranium and of its resultant decay chain will be important to any safety case for geological disposal over extended time frames. It is, therefore, ...

Using a mechanical system that alters the water-to-uranium fuel ratio, their reactor causes uranium-238 to absorb excess neutrons and produce plutonium to be used as fuel. This process recycles ...

An international team of scientists has identified an unexpected region of heavy, neutron-deficient isotopes in the nuclear chart where ... primary beam of uranium-238 at 87.6 percent of the ...
