Improvements in neutron radiography equiment at TREAT

A number of deficiencies became apparent in the Transient Reactor Test Facility neutron-radiography equipment after the system was in operation for several years. The deficiencies primarily resulted from changes in operating requirements. A new radiography-shield enclosure was built to incorporate automated transfer-foil insertion and provide adequate structural support of casks. It also precluded much of the time-consuming shield reconfiguration for various specimens. Reactor fuel-shortage holes were adapted for storage of most radiography specimens. This modification resulted in increased efficiency by decoupling the radiography operation from the specimen shipment operations
