Full reactor-E-N-load-review of the hazards from a chemical viewpoint

Description: chemical Research and Development Operation was contacted by R. Nilson of Irradiation Processing Department in order to obtain an analysis from a chemical viewpoint of the worst credible accident to a full E-N reactor loading. This analysis would be used to present to the ACRS directly or would be abstracted to prepare a supplementary report. The primary purpose of this report is to present an analysis of the chemical behavior of an E-N loading in the event of the sudden loss of coolant to the … more

Velocity Study of Centrifugal Pump Impellers

Description: A study was made to determine the magnitude of the velocities existing in the various slurry pumps currently in use and to determine possible methods of reducing the velocities in order to obtain longer life. The maximum velocities of the lOOA, 200A, and 300A pumps are between 39 and 53.6 fps with the exception of the lOOA absolute discharge velocity which is 80.6 fps. For large slurry pumps, it is recommended that lower speeds be used in order to reduce the impeller relative velocities. (auth)

Hazards Summary Report for the GCRE Critical-Assembly Experiments

Description: Critical experiments are described, and the hazards attendant to these experiments are evaluated for a gascooled water-moderated reactor design. Shutdown control of the critical assembly is achieved by cadmium control blades and by dumping the water into a storage tank. The maximum normal rats of reactivity addition is limited to an estimated 0.04 per cent per sec for all remotely controlled operations. The system is interlocked to insure that safe operational procedures are followed, Hazard ca… more

REFLECTIONS ON THE HOT-ZONE ATTACK OF INCONEL BY FUSED FLUORIDE

Description: Evidence is presented that the hot-zone attack of nickel-base alloys in contact with fused fluorides occurs by a grain-boundary diffusion process. Predictions based on tbe grain-boundary diffustion model are shown to copmpare favorably with existting data. Certain anomalies are pointed out with regard to the corrosion of Inconel by Fuel No. 20 (NaF-UF/sub 4/-ZrF/sub 4/) and tests which would lead to a better understanding of fused-salt corrosion are outlined.

DESIGN FEATURES OF CAPSULES FOR HIGH-TEMPERATURE IRRADIATIONS

Description: An analysis was made of the problems of control and measuremeat of specimen temperature and heat generation in a NaK-filled capsule containing a fuel specimen. A specific problem is used in this report to demonstrate the large uncertainties normally encountered even in capsules containing thermocouples. This analysis indicates that an improvement by a factor of more than three (i.e., from an uncertainty of plus or minus 7O F to plus or minus 2O F in the example used) may be obtained by use of a… more
