FACILITY DESCRIPTION: DOE Office of Health, Safety and Security Website:
Chapman Valve supplied valves to the MED and the AEC. In 1948, Chapman Valve machined uranium rods into slugs for the Brookhaven National Laboratory. Uranium slugs were used as reactor fuel. Chapman may also have conducted rolling operations on uranium metal in 1949. Bechtel National, Inc., with Interstate Nuclear Services and Thermo Nutech as subcontractors, performed remediation in 1995 as part of the Formerly Utilized Site Remediation Action Program (FUSRAP)
Documentation indicates that a radiological survey was performed at this site in 1991 with uranium contamination identified on floors, walls and overhead beams. Remediation actions were undertaken and a verification survey was completed in 1995 and confirmed that the remedial actions were successful in decontaminating the plant to applicable guidelines for unrestricted use.
Sources of information reviewed during this evaluation included:
DOE Office of Health, Safety and Security Website
Results of the Independent Radiological Survey at the Former Chapman Valve Company; Issued July 1992
Results of the Independent Radiological Survey at the Former Chapman Valve Manufacturing Company; Issued May 1997
Documentation reviewed indicates that there is a potential for significant residual contamination outside of the period in which weapons-related production occurred.
