Pumping plants

Fig. 1 Map of the Delta in central California, USA with the California state map inset to show location within the state. The Delta is formed at the confluence of the Sacramento River and the San Joaquin River. Export of water from the Delta occurs mainly from the State Water Project pumping plant and the Central Valley Project pumping plant in the south Delta...

Fig. 2 The Harvey O. Banks pumping plant, which pumps Delta water into the California aqueduct, is shown. The plant can pump up to 300 m /s and lifts the water about 73 m to begin the transit southward through the 710 km of canals, tunnels, and pipelines that constitute the California aqueduct...

A very extensive field research program was completed early in 1979, and the final report (prepared for the U.S. Army Corps of Engineers by Woodward-Clyde Consultants) was made available to the public in 1980 [1]. Within the limiting parameters determined by the contract, the specific purpose of the researchf and the grout pumping plant,J an extensive amount of data was gathered to evaluate not only the effectiveness of field procedures but the precision of various methods for evaluation of grouting effectiveness. 

J The grout pumping plant, although well engineered and sophisticated, was designed to be used as a volume control system. A pressure control system would have been more appropriate. 

He returned then to Stockton, where he had until 1897 his private practice. He became associated with the San Joaquin and Sacramento Rivers, and was retained for the reclamation of swamp land in their delta regions. He built 30 km of levees, 5 km of main canal, and large pumping plants for drainage.

Cornell University, Ithaca NY, a teaching career that lasted until 1942. Seery was promoted to assistant professor in 1907, and full professor of hydraulic engineering in 1918. He taught courses in water supply, hydraulic construction, water power and pumping plants, hydrauhc engineering, and reclamation problems. 

Several plants of this type exist in Geimany where the steam is used in industrial plants close by. This would be the case for the Schwarze Pumpe plant in Germany. 

The steam produced in the reactor pressure vessel is directed to the high-pressure part of the turbine downstream, the condensate formed on the high-pressure turbine is separated and directed to the heater drains. The residual steam powers the low-pressure part of the turbine and, finally, is completely condensed in the main condenser. The main condensate is purified in the condensate demineralizers where corrosion products and ionic impurities are retained. The feedwater then is recycled via preheaters to the reactor pressure vessel. In older BWR plants, all the condensates are purified in the condensate polishing system in the newer, forward-pumped plants only the main condensate is purified there, while the heater drains are directly pumped to the feedwater tank. In some of the BWR plants the feed-water tank is equipped with an electromagnetic filter for removal of suspended corrosion products (mainly iron oxides).
