Physicists Just Found The Lightest Known Form of Uranium, And It Has Unique Behaviors

Physicists Just Found The Lightest Known Form of Uranium, And It Has Unique Behaviors MARA JOHNSON-GROH, LIVE SCIENCE 4 MAY 2021 Scientists have discovered a new type of uranium that is the lightest ever known. The discovery could reveal more about a weird alpha particle that gets ejected from certain radioactive elements as they decay.   The newfound uranium, called uranium-214, is an isotope, or a variant of the element, with 30 more neutrons than protons, one fewer neutron than the next-lightest known uranium isotope. Because neutrons have mass, uranium-214 is much lighter than more common uranium isotopes, including uranium-235, which is used in nuclear reactors and has 51 extra neutrons. 

Doubts voiced about CGN nuclear project

Go-ahead will depend on several factors because of fallout from Sino-US situation There is uncertainty about the proposed China-involved construction of a nuclear power station near Bradwell in Essex in the United Kingdom, according to a minister with knowledge of the situation. The Financial Times reported on Wednesday that Gerry Grimstone, a minister in the Department for International Trade s Department for Business, Energy and Industrial Strategy, said questions hang over the proposed construction of the China-designed HPR1000 reactor. The plant has been proposed by General Nuclear System Limited, a joint venture involving China s State-owned China General Nuclear Power Group, or CGN, and the French state-owned energy company EDF.
