The U.S. currently has no permanent disposal facility for that radioactive waste, the NRC says. That means all waste from nuclear reactors — including SMRs and microreactors that could be built in ...

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 ...

Deep Fission’s reactors would be lowered on cables down a 30-inch, one-mile deep borehole. The reactors are pressurized-water designs, a common approach used in everything from nuclear ...

Although to most the term ‘fission reactor’ brings to mind something close to the commonly operated light-water reactors (LWRs) which operate using plain water (H 2 O) as coolant and with ...

Chinese scientists sustain plasma at 100 million degrees C for 1,066 seconds in EAST, advancing nuclear fusion research.

Several of the lighter, long-lived byproducts of fission, such as 99 Tc and 129 I, are more soluble in moist soil and therefore can more easily be transported to underground water supplies ...

Siemens Energy will be the sole supplier of steam turbines, generators and other auxiliary systems for Rolls Royce's future ...

Nuclear fission does not release the greenhouse gas, carbon dioxide. A controlled nuclear fission reaction releases one million times more energy per kg than a chemical reaction such as burning ...
