OSTI ID:4315401
Measurements were completed in the Lid Tank on the short experiment to ald in the design of control-instrument plugs. The plug was designed to increase the thermalneutron flux locally in the water beyond the pressure shell. This was accomplished by penetrating the water reflector and the steel and water thermal shield with an 8-in. diameter steel pipe fllled with lead, steel, or air. The measurements are compared with those of the unperforated shield. Neutron measurements were taken in water along the axis of the plug and also along the line perpendicular to and intersecting the plug axis. Gamma measurements were taken beyond the air-filled plug only. Neutroninduced secondary rays are predominant in determining the attenuation rate of the pressnre shell. (D.E.B.)
