PT IP-200-A, Temperature measurement of uranium swelling capsule

Description: In the development of fuel elements for the NPR, one potentially serious fuel element problem -- high temperature uranium swelling -- has not been experimentally investigated. A series of experiments has been proposed in which uranium fuel rod with different amounts of Zircaloy-2 cladding will be irradiated to high exposure at temperatures equivalent to those expected in an NPR. These experiments should show the importance of high temperature uranium swelling as a limiting factor in NPR fuel el… more

Production Test IP-168-A, Long term corrosion monitoring and evaluation of operating limits for I & E charges -- C-Reactor

Description: The performance of I & E fuel elements under the original tests{sup 1} was such that they are now being charged at C Reactor on a production basis. Data obtained from the original test, however, were not sufficient to indicate long term corrosion effects of the use of these elements, nor to accurately define their operating characteristics. It is the intent of this test, therefore, to provide for long term corrosion monitoring in tubes charged with and without water-mixing pieces; and to obtain… more

Corrosion test of irradiated uranium in monoisopropylbiphenyl (RM-171)

Description: The use of organic cooling media for nuclear reactors operating at high power levels predicates the use of a coolant which will not react violently with metallic uranium in the event of a fuel element failure. This report describes the testing, and subsequent examination, of two pieces of irradiated uranium which were immersed in monoisopropylbiphenyl (MIPB) at high temperatures and pressures for periods of time up to twenty-five days. The uranium samples had different irradiation histories and… more

EXAMINATIONS OF SPECIMENS AND SCALES TAKEN FROM THE HRT FOLLOWING RUNS 13 AND 14

Description: Following HRT runs 13 and 14, several metallic specimens were removed from the high pressure system and transferred to the Materials Section for examination. Samples of scale accumulation in the high pressure system were also taken after these runs and transferred to the Materials Section. Examination and analyses of these several specimens are still in progress, but some of the results are available and are reported. A possible interpretation of some of these results indicates that a considera… more

Development of Cermet Fuel Elements

Description: Fabrication techniques for making metal-ceramic fuel elements containing 80 to 90 vol. f UN or UO/sub 2/ in a Type 302B stainless steel matrix were investigated. A hot press-forging procedure was most successful for of theoretical or better. This procedure consisted of sealing the cold-p;ressed core compacts in stainless steel picuture-frame packs, heating to 1900 deg F, and pressing to a total reduction in thickness of 35%. A pressure approximately 50 tsi was used specimens produced by this me… more

TBP-Kerosene Solvent Degradation: Literature Search

Description: A search of the classified and unclassified literature concerning the degradation of a tributyl phosphate (TBP)-kerosene solvent has been conducted. Chemical Abstracts, Nuclesr Science Abstracts, Abstracts of Classified Reports, and the card file of the National Lead Company of Ohio's Library were included in the search. Pertinent information is presented, in abstract form, as it applies to extractant (TBP) degradation, diluent (kerosene) degradation, and solvent clean-up techniques. (auth)

The Application of a Nominal 48 WT % U-Al Alloy to Plate-type Aluminum Research Reactor Fuel Elements

Description: Under the Atoms-For-Peace Plan, the specification that uranium be limited to 20% enrichment in the U/sup 236/ isotope has necessitated development of a highly-concentrated uranium--aluminum alloy as the fuel material in the composite aluminum plates of research reactor fuel elements. Efforts have been directed to determining the suitability of a nominal 48 wt.% U--Al alloy in relation to previously established procedures for manufacturing platetype aluminum fuel elements. Increasing the uranium… more

Correlation of Cavitation Inception Data for a Centrifugal Pump Operating in Water and in Sodium Potassium Alloy (NaK)

Description: For the centrifugal pump under investigation, the static head at pump suction, in feet absolute, at cavitation inception was correlated for water and for 1500 F NaK on the basis of the differences of the vapor pressures of the two liquids. The difference between the vapor pressure of water and NaK, for the same conditions of pump speed and liquid flow, was added to the water-test cavitation inception value, and this estimate proved to be a good approximation to the experimental value found for … more

Stability of Ballistic Reentry Bodies

Description: Report discussing various features of the stability of ballistic reentry shapes, including considerations for ballistic-missile and manned-satellite reentry capsules. Attainment of satisfactory stability of reentry bodies with subsonic terminal velocities was not found to be too difficult, but undesirable features that may cause marginal stability characteristics may be introduced in an effort to minimize weight. Reentry bodies with supersonic terminal velocities have fewer stability issues.

Aerodynamic Heating of Blunt Nose Shapes at Mach Numbers Up to 14

Description: From Introduction: "The importance of blunt noses as a means of reducing the heat transfer to high velocity missiles has recently received much publicity. The question of just what blunt shape is best is still moot, and it is the purpose of this paper to present and examine some recent experimental results which may throw some light on this problem."

Effect of pressure level on afterburner-wall temperatures

Description: Report presenting an investigation conducted on a full-scale afterburner and turbojet engine to determine the effect of pressure level on afterburner-wall temperature. For a given ratio of cooling airflow to afterburner gas flow, the afterburner-wall temperature increased as afterburner-outlet pressure was increased. The results indicated that heat transfer by luminous radiation was not significant any pressure level investigated.

The Nitric-Hydrofluoric Acid Pickling of Zircaloy-2

Description: studied. Acid concentration, bath contamination, and temperature were the parameters investigated. Pickling rates were found to be linear with time. Pickling rates increased linearly with the HF concentration, but variations in the HNO/sub 3/ concentration had little or no effect on the rate. Contamination of the bath with metal ions found in Zircaloy-2 at concentrations below saturation also had little or no effect on the pickling rate. Temperature- dependency studies in the range of 40 to 160… more

Theoretical Studies of the Solidification of Uranium Castings

Description: The evaluation of factors involved in the production of sound uranium castings is the objective of a program of study now in progress. A mathematical model have been developed to calculate the time-temperature relationships in a cylinifical uranium casting during it solidification. Finite-difference equations are used, and the solution is obtained by use of a digital computer. Studies of the effects of such variables as the superheat, rate of pour, mold preheat, mold size, and others are possib… more
