In commercial power plants, there are two to four steam generators per reactor; each steam generator can measure up to 70 feet (21 m) in height and weigh as much as 800 tons. Each steam generator can contain anywhere from 3,000 to 16,000 tubes, each about .75 inches (19 mm) in diameter. The coolant (treated … Visa mer 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. They are used in pressurized water reactors (PWR) between … Visa mer Westinghouse and Combustion Engineering designs have vertical U-tubes with inverted tubes for the primary water. Canadian, Japanese, French, and German PWR suppliers use the vertical configuration as well. Russian VVER reactor designs use horizontal steam … Visa mer • Nuclear power plant • Power station • Steam turbine Visa mer Unlike PWRs, boiling water reactors (BWRs) do not use steam generators. The primary coolant is allowed to boil directly in the reactor core, and the steam is simply passed through a steam turbine. While theoretically simple, this has a downside for maintenance. … Visa mer Various high-performance alloys and superalloys have been used for steam generator tubing, including type 316 stainless steel, Alloy 400, Alloy 600MA (mill annealed), … Visa mer • John M. Dyke and Wm. J. Garland, Evolution of CANDU Steam Generators – a Historical View • Backgrounder on Steam Turbine Issues, Nuclear Regulatory Committee (March 21, 2014) Visa mer WebbThe causes and types of failures of steam generators manufactured by the two mentioned corporations are described. The failure causes include stress corrosion weakening of … WebbSince 1988, B&W has supplied 26 replacement PWR recirculating steam generators for non-B&W PWR's.
