The 4S is a fast neutron sodium reactor. It uses neutron reflector panels around the perimeter to maintain neutron density. These reflector panels replace complicated control rods, yet keep the ability to shut down the nuclear reaction in case of an emergency. Additionally, the Toshiba 4S utilizes liquid sodium as a coolant, allowing the ...
Small nuclear reactors, in comparison to conventional nuclear power plants, ... It was a potential deployment for the Toshiba 4S reactor. [193]
The project is intended to standardize the construction of nuclear power plants to cut down on cost and duration. According to the design, power plants could be built in as little as two years for $300 million. It is also a template, allowing for site-specific alterations with a plus or minus 20% cost predictability. [90]

In 2019, the Clinch River Nuclear Site was the first small modular reactor project to get an early site permit from the Nuclear Regulatory Commission, giving TVA the all-clear to move towards ...
U.K.-based Rolls-Royce SMR says its small modular reactors, or SMRs, are much cheaper and quicker to get running than standard plants, delivering the kind of energy security that many nations are ...
In April 2008, Marvin Yoder, a consultant on the project, said that Toshiba was planning to make the application to the Nuclear Regulatory Commission in 2009, and that if approval had been given in 2010 or 2011, the reactor could have been operational by 2012 or 2013. The company was also developing a 50 megawatt (electric) version of the reactor.
Hanford’s historic B Reactor, the world’s first full-scale nuclear reactor, went critical on Sept. 26, 1944. Wigner’s team had designed the Hanford reactors to house 1,600 process tubes.
