Pressurizer (nuclear power) - Wikipedia
WebIn a pressurized water reactor plant, the pressurizer is basically a cylindrical pressure vessel with hemispherical ends, mounted with the long axis vertical and directly connected by a single run of piping to the reactor coolant system. It is located inside the reactor containment building.
Pressurizer | Definition & Characteristics | nuclear-power.com
WebNov 30, 2014 · A pressurizer is a component of a pressurized water reactor. Pressure in the primary circuit of PWRs is maintained by a pressurizer, a separate vessel that is connected to the primary circuit (hot leg) and partially filled with water which is heated to the saturation temperature (boiling point) for the desired pressure by submerged electrical ...
Pressuriser - an overview | ScienceDirect Topics
WebJun 3, 2010 · A pressurizer is used to regulate the primary coolant pressure (≈ 150 bars) in PWRs and CANDU reactors. The pressurizer is connected to one of the hot leg pipings with a long surge line. Fig. 10.4 shows a typical pressurizer. Because of the contact between steam and liquid water, the water is also at the saturation temperature at steady state.
WebPRESSURIZER STEAM GENERATOR REACTOR A two-loop Westinghouse plant has two steam generato rs, two reactor coolant pumps, and a pressurizer. The two-loop units in the United States are Ginna, Kewaunee, Point Beach 1 and 2, and Prairie Island 1 and 2. Each of these plants has 121, 14 x 14 fuel assemblies arranged inside a reactor vessel that has
