The world's first and only nuclear power plant that put Gen IV reactors into commercial use is Shidao Bay Nuclear Power Plant. The reactor is a high-temperature gas-cooled reactor , started its building process on September 21 2014, [ 75 ] started to generate power December 20, 2021, [ 76 ] and was put into commercial operation in December 12 ...
The nuclear powered steam generator started as a power plant for the first nuclear submarine, the USS Nautilus. It was designed and built by the Westinghouse Electric Company power company for the submarine; from there the company started its development and research of nuclear-powered steam generators. [ 3 ]
BONUS was a prototype whose objective was to assess the economic and technical feasibility of the integral boiling superheating advanced reactor concept. [3] At the time, it was expected that developing higher-temperature reactors that could superheat steam was the next major step toward the achievement of a competitive status for nuclear power plants relative to fossil-fueled power plants.

The nuclear fuel cycle employs a full actinide recycle with two major options: One is an intermediate-size (150–600 MWe) sodium-cooled reactor with uranium-plutonium-minor-actinide-zirconium metal alloy fuel, supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor.
An LPCI is an emergency system which consists of a pump that injects a coolant into the reactor vessel once it has been depressurized. In some nuclear power plants an LPCI is a mode of operation of a residual heat removal system, also known as an RHR or RHS but is generally called LPCI. It is also not a stand-alone valve or system.
The AP1000 design traces its history to two previous designs, the AP600 and the System 80.. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in each ...
A nuclear reactor coolant is a coolant in a nuclear reactor used to remove heat from the nuclear reactor core and transfer it to electrical generators and the environment. Frequently, a chain of two coolant loops are used because the primary coolant loop takes on short-term radioactivity from the reactor.
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in inadvertant criticality.
