Title: HYDRAZINE PROCESS DEVELOPMENT. Interim Technical Engineering Report, August through October 1962

Technical Report ·
OSTI ID:4737278

Progress is reported on a program to develop, design, construct, and operate a continuous, in-reactor, hydrazine production loop based on the fissiochemical process approach. Fission fragment distribution studies, colloidal UO/sub 2/ preparation, improvements in uranium and hydrazine analytical techniques, in-reactor loop design modifications, flssion fragment deposition measurements for a variety of sources, correlation of experimental heat transfer data, and a parametric reactor systems analysis are discussed. Gas disengagement development is essentially complete. PVT relationships for nitrogen- hydrogenammonia mixtures are being experimentally determined over the 500 to 1000 psia, 100 to 200 deg F range. Distribution studies performed on the fission products of BMI slurry irradiations show that virtually all of the I/sup 131/ and about half of the Ru/sub 103/ are found in the decanted liquid phase; remaining non-volatile activity is adsorbed on the fuel particle surface. Three methods were evolved for converting aqueous UO/sub 2/ sols to colloidal UO/sub 2/ dispersible in liquid NH/sub 3/. Pump bearing lifetime was extended as the result of impeller shroud flange modifications. Specific area of enriched, particulated UO/sub 2/ increased from 0.6 to 2.0 m/sup 2/ grams during 0.06% burnup in the BMI slurry irradiation. Inreactor loop design was modified to incorporate a compact equipment cubicle within the MTR biological shield. The flux-measuring element was completed and delivered to the MTR. The hydrazine removal and fission gas holdup system was designed. The basic equation for the loop automatic control analysis has been translated into an analog format. Polarographic analysis showed no uranium contaraination in liquid samples filtered from LPTR irradiation capsules. Statistically reliable hydrazine G- values as high as 2.2 were obtained in recent LPTR runs. More accurate calibration of energy deposition showed G/sub NF/sub 3/ to be 4 in the N/sub 2/-F/ sub 2/-UF/sub 4/ irradiation. The solid state detection system was used to determine fission fragment energy deposition efficiency for U/sub 3/O/sub 8/- loaded glass fibers, UO/sub 2/ powders and plates, U metal plates, and U-Al plates. A variation of the Lyon equation was applied to correlate the data derived from heat transfer loop operations. A parametric reactor systems analysis was conducted on an unreflected, spherical, slurry reactor model at diameters of 8 through 10 feet. (auth)
