Remote equipment technology. Final report for GFY 1880

An interactive graphics terminal and a desk-top computer were utilized to perform a Computer Aided Remote Maintenance simulation of a hypothetical equipment item. The equipment item included an electrical connection, hydraulic fitting, and simple bolt pattern which were maintained by remote manipulators during the simulation. These remote maintenance operations demonstrated that the Computer Aided Remote Maintenance simulation technology could be extended to complex equipment items. As a result, these equipment items can be evaluated from the standpoint of remote operation and maintenance prior to purchase or installation in a remote processing or cell arrangement

High-burnup performance of mixed-oxide fuel rods clad in type 316SS of 0. 010- and 0. 015-inch wall thickness. [LMFBR]

Two short mixed-oxide fuel rods of LMFBR design configuration were irradiated to a burnup of approx. 12.5 atom % in GETR. Profilometry at several intervals during the test indicated that the rod with a 0.010 inch thick cladding exhibited a diametral strain of 0.17% per atom % burnup, while the rod with a 0.015 inch thick cladding exhibited a lower diametral strain rate of 0.12% per atom % burnup. These data present the opportunity for analytical methods to evaluate fuel rod dimensional changes without the complicating effect of metal swelling. Also, the rods incorporated a large plenum space so that pressure from released fission gases was extremely low. These measured strain rates are consistent with the range of fuel diametral strain rates that are associated with solid fission product swelling

Joint plant instrumentation program and integrated safeguards experiment. Final report

Mixed (uranium-plutonium) oxide standards were prepared and utilized to qualify available nondestructive assay equipment (gamma spectrometers, neutron counters, and calorimeters). Equipment was evaluated during normal operation in a plutonium facility. Measured material balances were calculated for two separate fabrication campaigns. Plutonium material unaccounted for values of less than 0.5% based on the total throughput was obtained in the final balance. A special test was undertaken to compare the plutonium content of single pellets determined by available nondestructive assay methods with controlled potential coulometric values. The implications of both programs on safeguards are summarized. (auth
