Natural fission requires specific environmental factors, including rich uranium deposits and groundwater, in combination with the correct geological makeup, to support the nuclear chain reaction. How ...

AI gives a thumbs up to Brett Bellmore innovative modifications to Robert Zubrin’s Nuclear Salt Water Rocket (NSWR).

Thermal neutrons are excellent for sustaining fission in reactors like TRIGA or thermal ... to drive a rapid, supercritical chain reaction, as seen in nuclear weapons or fast-spectrum reactors. A ...

For decades, the U.S. has led the race to clean, limitless nuclear fusion energy. Now China is catching up, spending twice as ...

Chinese engineers identify a design flaw in NASA's lunar nuclear reactor, suggesting improvements that could boost efficiency ...

Nuclear fission reactors struggle with two key problems: poor fuel utilization and complicated radioactive waste handling. To ...

In nuclear fission, atoms such as U-235 or Pu-239 split when a neutron hits them, releasing energy in the form of heat (along with more neutrons that can continue the chain reaction). This heat ...

Molten Salt Reactors (MSRs) are nuclear fission reactors in which either the fuel and/or the coolant is a molten salt. Molten salt is salt which liquifies at elevated temperatures and can store ...

Criticality refers to the state in which a nuclear fission chain reaction continues to occur within the reactor and the number of neutrons reaches equilibrium. A reactor that reaches a critical ...

A team from the Hefei Institutes of Physical Science, Chinese Academy of Sciences, has successfully developed a key system ...

Often called the holy grail of clean energy, nuclear fusion creates four times more energy per kilogram of fuel than traditional nuclear fission and ... to harness fusion reactions for power ...
