[en] The Neutron Radiography Reactor (NRAD) is located in the Hot Fuel Examination Facility (HFEF) at Argonne National Laboratory - West. HFEF comprises several large hot cells where both non-destructive and destructive examinations of highly irradiated reactor fuels are conducted in support of the LMFBR program. One of the non-destructive examination techniques utilized at HFEF is neutron radiography. The NRAD reactor is a TRIGA reactor and is presently operated at a steady state power level of 250 kW solely for neutron radiography and the development of radiography techniques. Radiographs are primarily taken at the NRAD facility using the indirect, or transfer method, whereby radiographs of a specimen are obtained without having to place gamma radiation-sensitive film next to the specimen. Thus, radiographs of irradiated as well as unirradiated specimens may be obtained. Techniques and procedures have been developed to perform track-etch radiography at the NRAD facility, which is a technique utilizing a cellulose nitrate type film in conjunction with a converter plate. Neutron tomography is one of the more recent techniques being perfected at the NRAD facility. In 1981 a new beam tube was added to the facility, which extends to a new radiography room where irradiated or unirradiated specimens are radiographed without having to be placed in the hot cell. The new beam tube has greatly extended the capability and utilization of the NRAD facility. Present plans for the NRAD reactor are to increase the operating power level from 250 kW to 1 MW in order to decrease radiography exposure times, which for tomography of large subassemblies are approximately 45 minutes
