National Research Corp.

Cambridge, Massachusetts

ALSO KNOWN AS: NRC

TIME PERIOD: 1944-1952; Residual Radiation 1953-1987


FACILITY DESCRIPTION: DOE Office of Health, Safety and Security Website:

National Research Corp. had Manhattan Engineer District experience in working with vacuum centrifugal castings, in developing jets and baffles for diffusion pumps, and in developing cold trap systems. National Research's work with vacuum centrifugal castings (contract W-7405-eng-293) involved casting tube alloy (uranium metal) using the "lost wax" technique. In 1948, National Research did work for Mallinckrodt involving the vacuum melting of approximately 500 pounds of uranium.

A December 1946 letter indicates that National Research Corp. requested a "leak detector for use in connection with some special development work on beryllium." It is not clear whether this work was ever actually done.


DISCUSSION:

Documentation reviewed indicates a potential for significant residual contamination outside of the period in which weapons-related production occurred. The location and/or facility and associated equipment used for these activities is described as a “shack” adjacent to the 70 Memorial Drive laboratory. Records indicate that the shack was demolished and replaced with an apartment building sometime prior to 1987.
