Small modular reactors (SMR s) are a class of small nuclear fission reactors, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations. The term SMR refers to the size, capacity and modular construction. Reactor type and the nuclear processes may vary.
NuScale Power Corporation. NuScale Power Corporation is a publicly traded American company that designs and markets small modular reactors (SMRs). It is headquartered in Portland, Oregon. A 50 MWe version of the design was certified by the US Nuclear Regulatory Commission (NRC) in January 2023. [3] The current scalable 77 MWe SMR VOYGR design ...
e. Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay. Nuclear fission was discovered by chemists Otto Hahn and Fritz Strassmann and physicists Lise ...
Reactor Overview. Small, sealed, transportable, autonomous reactor (SSTAR) is a proposed lead-cooled nuclear reactor being primarily researched and developed in the United States by Lawrence Livermore National Laboratory. It is designed as a fast breeder reactor that is passively safe.
The technical specifications of the 4S reactor are unique in the nuclear industry. [2] The actual reactor would be located in a sealed, cylindrical vault 30 m (98 ft) underground, while the building above ground would be 22×16×11 m (72×52.5×36 ft) in size. This power plant is designed to provide 10 megawatts of electrical power with a 50 MW ...
Energy Multiplier Module. The Energy Multiplier Module ( EM² or EM squared) is a nuclear fission power reactor under development by General Atomics. [ 1] It is a fast-neutron version of the Gas Turbine Modular Helium Reactor (GT-MHR) and is capable of converting spent nuclear fuel into electricity and industrial process heat. [ 2]
The US is dismantling nuclear warheads to power the next generation of reactors. Ella Nilsen, CNN. September 9, 2024 at 1:41 PM. Inside a highly classified facility in Oak Ridge, Tennessee — the ...
Safe affordable fission engine (SAFE) were NASA 's small experimental nuclear fission reactors for electricity production in space. [ 1] Most known was the SAFE-400 reactor concept intended to produce 400 kW thermal and 100 kW electrical using a Brayton cycle closed-cycle gas turbine. [ 2] The fuel was uranium nitride in a core of 381 pins clad ...
