- Summary
- Vibratory compaction of ThO/sub 2/ in 3/8-in.-OD stainlesssteel tubes with a pneumatic air-operated piston type vibrator gave densities from 8.7 to 9.0 g/cc. Thorium dioxide pellets, being developed for HR Blanket use, attained the highest densities when fired in an atmosphere of 75% N/sub 2/ and 25% CO. Thorium dioxide particles produced by flame denitration remained in the size range 1 to 2 mu when several different reflector temperatures and atomizing gas flows were tried. Four semicontinuous cyclic Sulfex declad and Thorex core dissolution of prototype Consolidated Edison fuel assemblies were made for determining reaction rates, dissolution rates, declad time, product loading, crosscontamination of the clad and core dissolvents and its effect on passivation and throium, and uranium losses to the declad solution. The mechanical equipment to dejacket the SRE fuel operated satisfactorily in initial mechanical tests. Commercial radiation protective coatings were evaluated under radiation up to 3 x 10/sup 9/ r. Vapor-liquid equilibrium data were obtained for boiling uranyl nitrate solutions. Detection of suspended granular dense solids is possible with a simple pneumatic density probe. Yankee Atomic flowsheet HETS values are reported for sieve and nozzle plates. A method of forming a bed in the horizontal section of a movable sodium fluoride bed for the volatility process was developed. A mathematical model was developed to describe the deposition of solids during the pot calcination of Darex waste. (For preceding period see CF- 60-2-56.) (auth)
