Supercritical water exists at temperatures above 374 °C and pressures above 220 atmospheres. Diagram of a supercritical water-cooled nuclear reactor. A supercritical steam generator is a type of boiler that operates at supercritical pressure and temperature, frequently used in the production of electric power.

The inverted U-tube bundle of a Combustion Engineering steam generator. A steam generator (aka nuclear steam raising plant ('NSRP')) is a heat exchanger used to convert water into steam from heat produced in a nuclear reactor core. It is used in pressurized water reactors (PWRs), between the primary and secondary coolant loops.
Steam generator (auxiliary boiler), a steam-powered boiler used on ships to produce a low-pressure steam, heated by a high-pressure steam supply rather than a flame. Steam generator (boiler), an oil- or gas-fired boiler, based on a low-water content monotube coil. Steam generator (nuclear power), a heat exchanger in a pressurized water nuclear ...
The SCWR operates at supercritical pressure. The reactor outlet coolant is supercritical water.Light water is used as a neutron moderator and coolant. Above the critical point, steam and liquid become the same density and are indistinguishable, eliminating the need for pressurizers and steam generators (), or jet/recirculation pumps, steam separators and dryers ().
Diagram showing the main components of a quick-acting stand-by power plant with a Velox steam generator. In a Velox steam generator used for electrical generation, flue gases from the combustion chamber are used to turn a gas turbine which is connected to a compressor which together make up the charging set.
Supercritical steam generators are frequently used for the production of electric power. They operate at supercritical pressure. In contrast to a "subcritical boiler", a supercritical steam generator operates at such a high pressure (over 3,200 psi or 22 MPa) that the physical turbulence that characterizes boiling ceases to occur; the fluid is ...
The Clayton forced-circulation steam generator does not have a steam drum in the typical sense. A series of small tubes that are part of one giant coil, usually made of steel, have feed water pumped through at great speed. The water is pumped from the top of the steam generator down to the bottom and out.
