Jul 26, 2018 · A reactor coolant loop is a reactor coolant pump, a steam generator, and the piping that connects these components to the reactor vessel. The primary function of the reactor coolant system is to transfer the heat from the fuel to the steam generators. A second function is to contain any fission products that escape the fuel.

Steam generator (nuclear power) - Wikipedia

The coolant (treated water), which is maintained at high pressure to prevent boiling, is pumped through the nuclear reactor core. Heat transfer takes place between the reactor core and the circulating water and the coolant is then pumped through the primary tube side of the steam generator by coolant pumps before returning to the reactor core.

Operation and Performance Analysis of Steam Generators in .

Mar 25, 2016 · Steam generators are components in which heat produced in the reactor core is transferred to the secondary side, the steam supply system, of the nuclear power plant (NPP). Steam generators (SGs) have to fulfil special nuclear regulatory requirements regarding their size, selection of materials, pressure loads, impact on the NPP safety, etc. The primary-side fluid is liquid water at the .

Boiling Water Reactor (BWR) Systems

Boiling Water Reactor Plant Inside the boiling water reactor (BWR) vessel, a steam water mixture is produced when very pure water (reactor coolant) moves upward through the core abso rbing heat. The major difference in the operation of a BWR from other nuclear systems is the steam voi d formation in the core. The steam-water mixture

Iceland Seeking 'Supercritical Steam' For Power Source .

The need to run on "dry" steam for efficiency is known at least from steam locomotives. The only modern power-generating subcritical steam systems I know of are some nuclear power plants where the reactor expects some of the cooling water in it to stay liquid (read: dense) because it serves as neutron moderator as well.
