PREPARATION OF STOICHIOMETRIC URANIUM MONOCARBIDE CYLINDERS

Description: Employing a modified arc-melting technique, homogeneous cylinders of stoichiometric UC were consistently produced. The cylinders ranged in size from 0.25-in. dia. by 1 in. long to 0.375-in. dia. by 3 in. long. The top 10% of nearly all cylinders did, however, contain shrinkage voids that could not be eliminated. UC buttons previously prepared by arc melting the elements were placed over a graphite-mold cavity, but in contact with Cu in an Aratmosphere arc furnace. When the UC charge became full… more

PHASE I REPORT OF DEVELOPMENT TECHNIQUES FOR POWER PRODUCTION FROM MIXED FISSION PRODUCTS

Description: An investigation was made into the various processes for the fixation of mixed fission products as solids in order to determine the extent they could be utilized as heat sources for thermoelectric generators. Generators of up to ten watts can be designed and built with state-of-art'' thermoelectric materials and mixed fission products soon to be available from the ldaho Falls calcination pilot plant. Mixed fission products from other processes and plants to be on stream'' in this decade will be… more

Development of a Fluidized Bed Calcination Process for Aluminum Nitrate Wastes in a Two-Foot-Square Pilot Plant Calciner. Part I. Equipment Development and Initial Process Studies

Description: A two-foot-square fluidized bed calciner was designed and operated to convert aqueous, highly radioactive wastes into granular solids. The calciner exceeded its designed feed capacity of calcining, at a bed temperature of 400/sup 0/C, 100 liters per hour of aluminum nitrate solution simulating wastes from the reprocessing of spent aluminum-uranium alloy reactor fuel. Heat was supplied to the calciner by circulating NaK with an electromagnetic pump, at temperatures up to 1400/sup 0/F, through a … more

QUARTERLY PROGRESS REPORT Research and development activities: fixation of radioactive residues. July-September 1965

Description: The calcined-waste containers produced during the Hot Cell Pilot Plant experiments in 1962 and 1963 have generated a maximum pressure of 3 psig. Design verification tests with the prototype spray calciner showed satisfactory performance when producing high melting point powders. Later tests on other feeds showed poor atomization and cake buildup in the calciner. Design of the prototype equipment is complete. Procurement and fabrication of prototype equipment is done except for a few cleanup ite… more

Low Temperature Polymorphic Transformations of Calcined Alumina

Description: The factors which affect the transformation of amorphous alumina to crystalline alumina in the temperature range 350 to 650/sup 0/C were studied. Amorphous alumina, with small amounts of added impurities, was heated in an atmosphere containing the oxides of nitrogen, air, and water vapor, and the amount of crystalline alumina was determined. Alpha alumina was the predominant crystalline form after heating amorphous alumina that was prepared in a fluid bed calciner. The effects of temperature, c… more

In-tank solidification of intermediate-activity wastes

Description: Solidification of intermediate-activity wastes is a major goal of the CPD Waste Management Program. Plans are to reduce the wastes, by evaporation, to salt cakes in existing tanks, thereby insuring safe, long-term storage of contained fission products regardless.of tank integrity. Initiation of these plans at an early date is necessary to offset the expected increase in tank failures and to provide space for future wastes. Major decisions of the program relate to selection of the evaporative me… more

Budget for FY 1966 and revised budget for FY 1965 separations research and development program: (02 50 10 15 1)

Description: This report presents additional justification for operating costs of the Separations Research and Development Program which consists of eleven identifiable activities in four general areas of effort. The activities and their proposed levels of effort are listed. For each of the identifiable activities, the major accomplishments of the last year are listed, together with the proposed goals for the next two years, in the following pages. Significant trends in the program are noted.
