Fernald Feed Materials
I want to introduct something about Natural Style Plate. Design: Imitation Stone Chinaware Tableware Origin: China Features: 1. Can supply a variety of ceramic plates. 2. Special design and sizes for Europe and America and other countries. 3. Unbelievable high quality, reasonable prices 4. OEM or ODM are welcome 5. Roughly finished stoneware for a more primitive, visceral experience. EQICHINA, The Famous Supply of China Hospitality Industry. (Redirected from Fernald, Ohio)The neutrality of this article is disputed. Please see the discussion on the talk page. Please do not remove this message until the dispute is resolved. (April 2008)The Fernald Feed Materials Production Center (commonly referred to simply as Fernald) was a uranium processing facility located near the rural town of Fernald, in Hamilton County, Ohio, about 20 miles northwest of Cincinnati, which fabricated uranium fuel cores for the U.S. nuclear weapons production complex from 1951 to 1989.Contents1 History 2 Production facilities 2.1 Plant 1 2.2 Plant 2/3 2.3 Plant 4 2.4 Plant 5 2.5 Plant 6 2.6 Plant 7 2.7 Plant 8 2.8 Plant 9 2.9 Pilot Plant 3 See also 4 References 5 External links // HistoryThe neutrality of this article is disputed. Please see the discussion on the talk page. Please do not remove this message until the dispute is resolved. (April 2008)In 1948 the Atomic Energy Commission, predecessor to the U.S. Department of Energy, established large scale integrated facility for the production of fabricated uranium fuel cores by chemical and metallurgical techniques." The plant was known as the Feed Materials Production Center since the uranium fuel cores it produced were the eed for the AEC plutonium production reactors.1 These nuclear reactors were located at Oak Ridge in Tennessee, the Savannah River Site in South Carolina and at Hanford in the state of Washington. The uranium metal produced was in the form of derbies, ingots, billets and fuel cores.1 The FMPC also served as the country central repository for another radioactive metal, Thorium.The plant was located in the rural town of Fernald which is about 20 miles northwest of Cincinnati, Ohio and occupies 1,050 acres. This location was chosen because it was between the uranium ore delivery ports of New York and New Orleans, and it was accessible to the other main AEC sites. In addition, the site was close to Cincinnati large labor force, the landscape was level making the site construction easy, it was isolated which provided safety and security, and it was located 30 to 50 feet above a large water aquifer which supplied the water needed for uranium metal processing.From 1951 to 1989 Fernald converted uranium ore into metal, and then fabricated this metal into target elements for nuclear reactors. Annual production rates ranged from a high in 1960 of 10,000 metric tons to a low in 1975 of 1,230 metric tons.2 Refining uranium metal was a process requiring a series of chemical and metallurgical conversions that occured in nine specialized plants at the site.Releases from the Fernald site to the surrounding area resulting in exposure to community residents included ionizing radiation, soluble and insoluble forms of uranium, and various other hazardous chemicals. The Centers for Disease Control and Prevention (CDC) has conducted a historical exposure characterization and developed dose estimation models through the Fernald Dose Reconstruction Project, with an endpoint of developing an algorithm to estimate doses to individual persons who lived within the exposure assessment domain (the area within a ten kilometer radius from the center of the plant site). In addition to radioactive materials, many other non-radiological toxic substances were present in the production area as materials, by-products or products. Workers were exposed to chlorinated and non-chlorinated solvents, metals and metal salts, and nuisance dusts.3-10 Community residents may have been exposed to these substances through ground water pathways, soil contamination, and air dispersion of emissions from the site.Two separate medical surveillance programs, for former workers and community residents, have been funded by settlements of class action litigation against National Lead of Ohio, a contractor for the DOE. These Fernald Settlement Funds are administered by the US Federal Court, which maintains oversight of the Fernald Medical Monitoring Programs. The Fernald (Residents) Medical Monitoring Program (FMMP) is a voluntary ongoing medical surveillance program for community residents living within five miles of the perimeter of the Fernald site, and the Fernald Workers Medical Monitoring Program (FWMMP) is a program for former workers who were employed when National Lead of Ohio was the contractor. Activities of the medical monitoring programs include both periodic medical examinations and diagnostic testing and yearly questionnaire data collection.As of January 1, 2007 there were 9764 persons enrolled in the FMMP and 2716 former workers enrolled in the FWMMP. The FMMP has an extensive computer database available for research studies. Samples of whole blood, serum, plasma and urine were obtained from all FMMP participants at the time of the initial...(and so on) To get More information , you can visit some products about sullair air compressor, refractory products, .
