Postirradiation Examinations of Fuel Pins from the GCFR F-1 Series of Mixed-Oxide Fuel Pins at 5. 5 at. % Burnup

Description: Postirradiation examinations were performed on five fuel pins from the Gas-Cooled Fast-Breeder Reactor F-1 experiment irradiated in EBR-II to a peak burnup of approximately 5.5 at. %. These encapsulated fuel pins were irradiated at peak-power linear ratings from approximately 13 to 15 kW/ft and peak cladding inside diameter temperatures from approximately 625 to 760°C. The maximum diametral change that occurred during irradiation was 0.2% .delta.D/D₀. The maximum fuel-cladding chemical interact… more

The Production of the Light Rare Earths in the Massive Metallic State

Description: Abstract: "Cerium, lanthanum, praseodymium and neodymium metals have been prepared in high purity in the massive state by reducing the appropriate rare earth chloride with calcium metal, using iodine as an auxiliary oxidant. Vacuum remelting of the product metal is employed to eliminate small amounts of calcium and magnesium. Attempted reductions of samarium and yttrium halides have not been successful."

Examination of Irradiated Uranium-Chromium Alloy Slugs

Description: Production Test 313-105-13-M authorized the irradiation of a uranium - 0.4 atomic per cent chromium alloy to determine the relative stability of this material during irradiation. Five tubes, each containing six four-inch alloy slugs, were irradiated to exposures ranging from 156 to 834 MWD/T. This report describes the results of the visual examination of the bare uranium alloy slugs and the results of the test to determine slug breaking strength. The breaking strength of both the U-Cr alloy slu… more

The Radiolysis of Xylene Isomers and Ethylbenzene

Description: The G-values for the formation of H₂ and CH₄ in the Co60 gamma radiolysis of the xylene isomers and ethylbenzene were compared. The presence of iodine does not affect GH2, but reduces GCH4 a limiting value. For p-xylene, GH2 and the unscavengeable CH₄ yield are independent of temperature from 20 to 110 deg C, whereas the total CH₄ yield increases six-fold over this range. The H₂ and CH₄ yields are greatly reduced in the solid state, and in the liquids state benzene shows a protective effect on … more

Progeny Test from a Pitch Pine-Oak Forest, Damaged by Low Level Chronic Gamma Radiation

Description: Ionizing radiation is useful to plant breeders in obtaining mutations beneficial from an economic point of view. This report, however, concerns our basic knowledge of radiation: attention is here directed to some effects of low level radiation on the R₁ progeny. Approximately one third of the land area of the United States is covered by forest; thus, forest trees form an important component of our natural wealth. It is therefore our obligation to know how these forests will react to low level i… more

Fundamental Problem of Late Neurological EffectFollowing Acute Irradiation

Description: Since the end of the last century (Tarknow, 1896) radiation effect o the nervous tissue has been studied in experimental animals and humans by numerous investigators, using mostly pathomorphological changes as a parameter of radiosensitivity . With increasing time intervals following radiation, pathomorphological changes are more evident, which has been known for quite some time.

Radiation Damage in Solid Tetramethyl Ammonium Halides. Free Radicals Stable at Low Temperature

Description: Electron spin resonance (ESR) spectral studies were carried out on tetramethyl ammonium halides which were irradiated at 298 and 77 deg K. The ESR spectra of the iodide and bromide irradiated at 298 deg K consisted of a single line of width 30 to 40 gauss, while that of the chloride gave a weak complex pattern. When the irradiations and ESR studies were performed at 77 deg K, considerable fine structure was observed which was centered about g = 2.003 plus or minus 0.001. The iodide spectrum at … more

The Influence of Radiation-Produced Defects on the Precipitation of Carbon in Iron

Description: Iron containing approximately 0.01 wt. % carbon was quenched from 700°C and irradiated in the BNL reactor at 57°C for various lengths of time. The rate of decay of the Snoek internal friction peak was observed at 57°C after irradiation. After a 4-hour irradiation the rate of decay of the peak was one order of magnitude faster than the rate of decay in an unirradiated specimen. Longer irradiation times up to 48 hours caused no further acceleration of the decay rate. This observation implies that… more

The Thermal Decomposition of NaBrO₃, Part 2: Irradiated Material

Description: Studies of the thermal decomposition of NaBrO₃ reported in Part I have been extended to include material pre-irradiated with Co₆₀ y-ray and reactor irradiations. The primary effect of the irradiation appears to be an enhancement of the melting rate of the eutectic formed between NaBrO₃ and the product NaBr, and is accompanied by an enhanced decomposition rate. The conclusion reached with unirradiated material that alternate decomposition routes exist such as at dislocations and other defects is… more
