THE DESIGN, CONSTRUCTION, AND EQUIPMENT OF A NEW HIGH LEVEL RADIATION LABORATORY AT NRL
Abstract
A new NRL High Level Radiation Laboratory is described, with special emphasis on the design, construction, and collateral equipment. This laboratory provides a means for safely handling and conducting research on gamma-active materials of interest to the Navy. The facility includes: five hot cells, with three designed for 1,000 curies and two designed for 10,000 curies of 1-Mev gamma; isolation cubicles back of cells; a 'warm' work area; a decontamination room; x-ray laboratory; radiochemistry laboratory; machine shop; isotope storage facilities; waste disposal system; 'cold' laboratories; and offices and utilities area. Design innovations discussed include: steel-lined cells; allglass windows with exceptional viewing angle and clarity; manually operated hinged steel shielding doors; internal and external transfer drawers; special receptacle panels in cells; cell lighting; underwall U-tubes; underwindow access ports; removable roof plugs; isotope storage; waste disposal system; and gas scrubber. Equipment discussed includes: heavy-duty master-slave manipulators; mechanical arm manipulators and bridge cranes in cells; through- the-wall periscope; throughthe-wall stereomicroscope; a remotely controlled shielded metallograph with through-the-wall specimen transporter; and metallographic specimen preparation equipment. Results of tests with a 9,500- curie Co-60 source on the shielding integrity of the facility are presented.
