Sodium Graphite Reactor. Quarterly Progress Report, July-September 1954

Description: Technology of the Sodium Graphite Reactor. Reactivity calculations were made to study the application of steadystate plutonium feedback techniques to the use of diffusion plant tails for reactor fuel feed material. The performance and design of a twin core SGR power plant are given. Thermal neutron flux distribution measurements are reported for a six-rod fuel cluster and for a hollow uranium rod. A power cost calculation was made for a 1000-Mw SGR Th-U/sup 233/ breeder reactor which starts up … more

Probability of ruthenium reduction in H-4 by self-radiation

Description: The following calculations have been made at the request of H.R. Schmidt to determine the probability that self-radiation may play a substantial role in the decomposition of the ruthenium tetroxide in the reflux scrubber, section of the Redox Ruthenium Oxidizer (H-4). The validity of the derived data necessarily depends upon the correctness of the basic assumptions made with regard to process conditions and to possible radiation-activated mechanisms of disintegration. It is estimated that the e… more

Final reports on PT 105-551-A and Supplement A, ``High exposure thorium`` and PT 105-516-A, ``Effects of irradiation of thorium slugs``

Description: This report discusses Production Test 105-516-A which was written to determine the stability by both measurement and visual examination, of thorium slugs as used in flattening columns to exposures in excess of 400 MWD/AT. Both rolled and extruded thorium slugs were used; the highest exposures reached were about 1000 MWD/AT. Also discussed is Production Test 105-551-A which was written to demonstrate the stability of thorium slugs as used in flattening columns at exposures up to approximately 15… more

DIFFERENTIAL THERMAL ANALYSIS OF IRRADIATED DIAMOND AND SILICON CARBIDE

Description: It was demonstrated by differential thermal analysis (DTA) that: 1. Catastrophic amounts of energy can be stored in diamond. 2. Even at low irradiations, the release takes place over several hundred degrees, indicating a spectrum of activation energies. 3. At higher irradiations, the stored energy release is considerably less than the increased energy content and seems not to have been completely released even at the highest temperatures reached. 4. There is some indication of an increased heat… more

Production Test No. 105-519-SI irradiation service request No. HAPO 108: Studies of uranium crystal structure damage using low irradiation temperatures

Description: This document discusses studies of the behavior of uranium metal as a fuel element which previously have been hampered by the lack of understanding of the nature of radiation damage to the crystal structures. With the aid of the double crystal x-ray spectrometer, samples from irradiated fuel elements which had receive total exposure of 150 MWD/T and 1,000 MWD/T were studied and gross radiation damage was not present. Although these findings are of a preliminary nature, they are well in agreemen… more

Final report for Process Test MR-105-4 -- Radiation effects of the removal of front cap supported shielding slugs

Description: Corrosion of aluminum front cap supported shielding slugs has been noted at all reactors except C Reactor which has galvanized shielding pieces. There has been a considerable amount of difficulty caused by sticking of the places. The difficulty is caused by the growth of corrosion products in the annulus around the shielding piece which affectively siezes it. As recently as June, 1953 the shielding pieces on nearly 50 per cent of a group of 40 tubes at B Reactor were corroded to the extent that… more
