Description: According to the Callaway Plant Media Guide, the plant design utilizes the Standardized Nuclear Unit Power Plant System (SNUPPS). Ameren owns 7,200 acres of land at the site, of which 6,300 acres is administered by the Missouri Department of Conservation. The plateau on which the plant is located is 300 feet above the Missouri River. The reactor containment building is 205 feet tall, 150 feet in diameter, and constructed of concrete and reinforced with steel. The cooling tower is 553 feet tall (the media guide notes that it is only 77 feet shorter than the Gateway Arch in St. Louis, Missouri). The tower cools approximately 585,000 gallons per minute. The Missouri River supplies the water. Units Name
Nuclear Steam System Supplier (NSSS Vendor) = Westinghouse Electric Company
Pressurized-Water Reactor (PWR) In a typical commercial pressurized light-water reactor (1) the reactor core generates heat, (2) pressurized-water in the primary coolant loop carries the heat to the steam generator, (3) inside the steam generator heat from the primary coolant loop vaporizes the water in a secondary loop producing steam, (4) the steam line directs the steam to the main turbine causing it to turn the turbine generator, which produces electricity. The unused steam is exhausted to the condenser where it is condensed into water. The resulting water is pumped out of the condenser with a series of pumps, reheated, and pumped back to the steam generator. The reactors core contains fuel assemblies which are cooled by water, which is force-circulated by electrically powered pumps. Emergency cooling water is supplied by other pumps, which can be powered by onsite diesel generators. Other safety systems, such as the containment cooling system, also need power.
Containment: According to the U.S. Nuclear Regulatory Commission, the containment is dry, ambient pressure. _________________________________________ 1Dry, Ambient Pressure: a reactor containment design whose safety has been evaluated on the basis of having a dry air atmosphere at ambient pressure (0 psig) prior to the onset of a loss of coolant accident or steam pipe break. The containment design (concrete and steel tendons) must be able to take the full thermal and pressure stresses associated with the rapid energy release (steam) from a major pipe break. |
