The reactor coolant piping and components are generally referred to as the reactor coolant system, even though the RCS also includes the reactor vessel and the components directly attached to the reactor vessel.
The primary system (also called the Reactor Coolant System) consists of the reactor vessel, the steam generators, the reactor coolant pumps, a pressurizer , and the connecting piping. A reactor coolant loop is a reactor coolant pump, a steam generator, and the piping that connects these components to the reactor vessel.
Each reactor coolant pump (RCP) is a high-inertia, high-reliability, low-maintenance, hermetically sealed canned-motor pump that circulates reactor coolant through the RV, loop piping, and SGs.
Pressurized Water Reactor (PWR):Major Systems
The reactor coolant system of the pressurized water reactor (PWR) consists of a reactor vessel, steam generators, reactor coolant pumps, a pressurizer, and other elements. These principal components are interconnected by the reactor coolant piping to form a loop configuration.
Pipe and tube products are widely used within a nuclear power plant. From PCC Energy Group we supply many of those essential products, including: Primary and secondary reactor coolant loop piping, surge lines, steam generator tubing, essential service water, and turbine feed lines.
PWR Reactor Coolant System - Nuclear Tourist
Mar 15, 2001 · The sketch below illustrates the Reactor Coolant System's major components- Reactor Vessel, Steam Generators, (Reactor) Coolant Pump, and Pressurizer. Click to see a 51K detailed drawing of the RCS with parts identified.
Two to four loops connect to the RPV. Each loop consists of a steam generator, reactor coolant pump, and piping. The piping between the RPV and the steam generator is called the “hot leg.” The piping from the steam generator to the reactor coolant pump and back to …
Reactor Cooling Systems-PWR/BWR - Nuclear Tourist
Cool the reactor from the hot normal operating temperature (~ 500F) to the cold or refueling shutdown temperature. The Reactor Cooling System design varies with type: This design uses high pressure (1500 to 3000 pounds per square inch) piping nominally 1.5 to 3 feet (0.5 to 1 meter) in diameter.
Flow rate of primary coolant that carries heat away from the nuclear fuel is an important measurement in pressurized water reactors (PWRs). Insufficient cooling can result in fuel damage, core melt, and radioactive release to the environment, if unmitigated.
The primary system (also called the reactor coolant system) consists of the reactor vessel, steam generators, reactor coolant pumps, a pressurizer, and connecting piping (Figure 1.2-1). A reactor coolant loop is a reactor coolant pump, a steam generator, and the piping that connects
