Winchester Engineering And Analytical Center

Also Known As: U.S. Public Health Service; N.E. Radiological Laboratory, Northeastern Radiological Health Laboratory, National Lead Co., AEC Raw Materials Development Laboratory
State: Massachusetts
Location: Winchester
Time Period: 1952-1961
Facility Type: Department of Energy

Facility Description

The Winchester Engineering and Analytical Center, built in 1952 under sponsorship of the AEC, was used to continue development of methods for extraction of uranium and thorium form ore and to prepare metal grade uranium tetrafluoride. Massachusetts Institute of Technology (MIT) began the work in 1946 at Cambridge, MA and continued the work after it was transferred later that year to Watertown Arsenal, Watertown, MA. American Cyanamid Company succeeded MIT in operating the project at Watertown Arsenal from 1951 until October 1952, when it was transferred to the Winchester Facility. In 1954, National Lead Company, Inc. took over operations under AEC contract AT(49-6)-924. Beginning in 1959, facility use shifted to laboratory testing of environmental analysis methods pertaining to uranium waste. In 1961, the work was discontinued, and the facility was transferred to the Department of Health, Education and Welfare (HEW) for use as a low-level environmental radiation surveillance laboratory and for analysis of radiopharmaceuticals. The facility is now run by the Food and Drug Administration.

CONTRACTORS: National Lead Company (1954-1961); American Cyanmid (1952-1954)

Site Description

The research facilities of the Raw Materials Development Laboratory were located at Winchester, Massachusetts, a residential community about 15 miles from Boston. The laboratory building, constructed in 1952, is a modern, single-story, cement block and brick building with a floor area of 31,400 square feet (Figure 1). The building was divided into approximately thirty laboratories, work areas,shops and offices and was equipped and staffed for conducting awide variety of metallurgical, chemical and analytical investigations. Figure 3 shows a floor plan of the laboratory. A small test plant was available for continuous unit process testing. Well equipped machine and instrument shops provided for the maintenance and construction of standard and specialized equipment.

The laboratory was divided into three departments: Metallurgical, Chemical, and Analytical. The laboratory was equipped for investigations into acid and alkaline leaching techniques, ion exchange, solvent extraction, and precipitation processes. Facilities were also available for conducting mineralogical studies, flotation,gravity concentration, magnetic and electrostatic separations. A

well equipped crushing and sampling laboratory assured careful preparation and sampling of the ores received for testing. Figure 4and 5 show the mineral dressing laboratory and the sample preparation room, respectively.

The analytical facilities contained besides the usual equipment for wet-chemical analyses a complete emission spectrograph laboratory,spectrophotometers and polarographs of both the recording and non-recording types, radiometric counting equipment, and other modern analytical instruments. Figures 6 through 9 show views of some of the chemical and analytical facilities.
