Westinghouse's world headquarters are located in the Pittsburgh suburb of Cranberry Township, Pennsylvania. The company's main product is the AP1000, a modern pressurized water reactor (PWR) design with many passive safety features and modular construction intended to lower construction time and cost. Twelve AP1000 reactors are currently in ...
Steam turbine generator: The first commercial Westinghouse steam turbine-driven generator, a 1,500 kW unit, began operation at Hartford Electric Light Co. in 1901. The machine, nicknamed Mary-Ann, was the first steam turbine generator to be installed by an electric utility to generate electricity in the US.
More recently, the cost of solar in Japan has decreased to between ¥13.1/kWh to ¥21.3/kWh (on average, ¥15.3/kWh, or $0.142/kWh). [133] The cost of a solar PV module make up the largest part of the total investment costs. As per the recent analysis of Solar Power Generation Costs in Japan 2021, module unit prices fell sharply.
The Westinghouse Combustion Turbine Systems Division (CTSD), part of Westinghouse Electric Corporation's [1] Westinghouse Power Generation [2] group, was originally located, along with the Steam Turbine Division (STD), in a major industrial manufacturing complex, referred to as the South Philadelphia Works, in Lester, Pennsylvania near to the Philadelphia International Airport.
It generates electricity from one 1,190-megawatt Westinghouse four-loop pressurized water reactor and a General Electric turbine-generator. The Ameren Corporation owns and operates the plant through its subsidiary Ameren Missouri. It is one of several Westinghouse reactors designs called the "Standard Nuclear Unit Power Plant System," or SNUPPS ...
The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side.
The AP1000 design traces its history to two previous designs, the AP600 and the System 80.. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in each ...
At 9:56 a.m., after trying multiple times to start the 1-A EDG normally, plant operators performed an emergency startup of the EDG by activating the generator's emergency start "break-glass" which bypassed most of the EDG's safeties and forced it to start. The startup was successful. RHR-A was then started using power from EDG-A.
