Description: The Kewaunee nuclear plant occupies a 900-acre site in Carlton, Wisconsin, about 35 miles southeast of Green Bay. Management of the site was consolidated with the Point Beach units. Kewaunee was the fourth nuclear plant built in Wisconsin, and the 44th built in the United States. In June 2005, the plant was acquired by Dominion from its previous owners, Wisconsin Public Service Corporation and Alliant Energy. The Virginia-based company owns the North Anna and Surry plants in its home state, and acquired one other out-of-state plant, Millstone (in Connecticut). Kewaunee, Unit 1
Nuclear Steam System Supplier (NSSS Vendor) = Westinghouse Electric 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, containment type for Kewaunee’s PWR is dry, ambient pressure.1 _________________________________________ 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. |
