An international collaboration of scientists working with the FAIR Phase 0 program at the GSI Helmholtzzentrum für ...

Thermal nuclear weapon, also known as hydrogen bomb, is a type of nuclear weapon which is based on the nuclear fusion process ...

An NTI nuclear expert writes that it was disappointing to see used nuclear fuel reprocessing play prominently in executive ...

Nuclear fission is the process of breaking large ... count in its nucleus — of the heavy elements uranium or plutonium. The energy needed to kick start fission is around 7 to 8 million ...

More commonly, fission is used to generate energy within a nuclear power plant. Power plants typically use uranium and plutonium isotopes because these reactions are easiest to control ...

Subtle quantum effects within atomic nuclei can dramatically affect how some nuclei break apart. By studying 100 isotopes ...

A part of the fission energy carried away by ... from reactor designers to practitioners of nuclear medicine. “The PFBR uses plutonium recovered from CANDU spent fuel and so will contain ample ...

Outdone only by nuclear fusion, the process of nuclear fission releases enormous amounts of energy. The ‘spicy rocks’ that are at the core of both natural and artificial fission reactors are ...

If fission starts with a certain minimum amount — known as critical mass — of radioactive material such as uranium and plutonium, it causes a chain reaction, Zaijing Sun, a nuclear physicist ...

Nuclear power is generated by splitting atoms to release the energy held at the core, or nucleus, of those atoms. This process, nuclear fission, generates heat that is directed to a cooling agent ...

Weapons are supercritical: The plutonium is compressed enough to sustain chains of nuclear fission reactions, the splitting of atomic nuclei. The chain reactions occur because fission spits out ...

nuclear bombs, if there even is one ... such as refined uranium or plutonium, a fission chain reaction, where more and more atoms are split by the neutrons emitted from previous splits, can ...
