Design of supplement B to PT-IP-262-A-11-FP, evaluation of projection fuel elements for use in ribbed process tubes

Description: One of the three major categories of HAPO fuel element failures is the side corrosion type rupture. The majority of side-corrosion failures has been characterized by oval or tear-drop shaped flow patterns containing evidence of accelerated corrosion. Thorough examination of many of these so-called `hot spot` failures has indicated the failure was caused by poor heat transfer associated with misalignment, dimensional distortion or poor jacket-to-core bonding. It has been postulated that misalign… more

IPD production projections

Description: Two changes have been incorporated in the tables of this draft: (1) The lithium-aluminum tonnages required for blanket and E-N loadings have been changed, (2) The production numbers for the small production reactors have been reduced per AEC direction, and a separate table is included for these numbers. Included data are power levels, operating efficiency, exposure, tonnage, conversion ratios, and annual production for the C, K, and small reactors.

THE EXPERIMENTAL DESIGN FOR BeO IRAADIATION EXPERIMENTS ORNL 41-8 AND ORNL 41-9

Description: The experimental plan for irradiating BeO pellets in Experiments ORNL 41- 8 and ORNL 41-9 was chosen in accordance with the principles of experimental design. The design is known by statisticians as a 2/sup 5/ factorial experiment confound'' in six replications. Five variables---size, density, grain size, temperature and time--are controlled at two levels to form the basic 2i factorial experiment. The sixth variable, neutron flux, is introduced by confounding on higher-order interactions. An ex… more

Carbide Cathode Studies, Physical and Chemical Redeposition. Quarterly Progress Report, April 1, 1962-June 30, 1962

Description: The utilization of physical and chemical processes to reduce the rate of vapor loss of thermionic emitters composed of mixed carbides of U and Zr in order to increase the permissible operating temperature is being studied. Preliminary, qualitative results obtained from study of physical redeposition processes showed that increasing the collector temperature may markedly reduce the rate of weight loss from a UC emitter operating at 2053 deg K. The requisite experimental equipment for studies of … more

"Life" Tests on Internally Water-Cooled Hollow Copper Conductors

Description: Tests were conducted to determine whether a time limitation exists on the use of internally water-cooled hollow copper conductors operating at densities of up to 330,000 amps/in/sup 2/. Using demineralized water, having a specific resistivity of 4 to 9 x 10/sup 6/ ohm-cm, no indication of a decrease in heat transfer coefficient as a function of time was observed. However, metallographic examination revealed that corrosion--erosion does occur at a slow rate. Using process water there was a time … more

RADIOISOTOPE AND RADIATION APPLICATIONS. Quarterly Progress Report

Description: The study of the formation mechanism of free radicals in polymeric materials was continued. Emphasis was placed on an examination of the effect of structural factors on the efficiency of free-radical site formation in acrylate polymers. Site measurements as a function of dose were made for polymethacrylamide and repeated for polymethacrylic acid. The volatile products from the irradiation of polyacrylic acid. polymethacrylic acid, poly-ter- butylmethacrylate. and polycyclohexyl methacrylate wer… more

Optical Emission From Irradiated Thin Metallic Foils

Description: Thin metallic foils were irradiated with a 15 microampere beam of electrons from an accelerator operating between 50 to 115 kev. The light emission spectrum from the foils was analyzed with a Seya-Namioka Vacuum UV Monochromator with an EMl 6256B photomultiplier tube as detector. The metals irradiated with silver, aluminum, and gold with the former being unbacked and the latter two supported on thin organic substrates. The silver and aluminum data were compared with previously derived theories … more

SEMI-ANNUAL REPORT FOR THE PERIOD JANUARY 1 TO JUNE 30, 1963

Description: The 6-Bev strong focusing electron synchrotron continued to operate weli. Three-shift operation was began, one shift being devoted to machine maintenance and improvement and two shifts being devoted to serving the various groups of experimentalists. Brief descriptions of the experiments are presented. New equipment was obtained, an external positron beam (10/sup 6/ particles/sec) was established, and preparations for trial production of an external electron beam were completed. (N.W.R.)

River Soundings. Core I, Seed 2. Test Results

Description: Water depth in the intake channel to the coolant-water screenhouse and surrounding area in the Ohio River near the intake channel were measured. From these measurements, the amount of silt removed during a previous dredging was determined. (C.J.G.)
