The solution of the shielding problems encountered in the Enrico Fermi Reactor are given. The shield has been designed from common materials whose durability over the expected life of the plant is known and whose cost is low. These are graphite, steel, and concrete, all used in the primary, secondary, and biological shields. Special shields are necessary around the 30-in. primary- coolant outlet lines because of the large neutron leakage. Two materials were considered for this shield: (a) borated, diatomaceous-earth-aggregate lumnite concrete and (b) pressed calcium borate mnterial. The lntter was chosen as the shield. Temperatures to be expected in the primary-coolant pump and heat- exchanger plugs preclude the use of ordinary concrete as plug shields. The present design calls for a concrete made from serpentine rock aggregnte in lumnite cement within the plug containers. Costs of the shielding materials are given. Elevation and plane views of the reactor give the locations of the shields. The shielding properties of the shields are presented graphically. (T.B.A.)
