SIEX: a correlated code for the prediction of Liquid Metal Fast Breeder Reactor (LMFBR) fuel thermal performance

Description: The SIEX computer program is a steady state heat transfer code developed to provide thermal performance calculations for a mixed-oxide fuel element in a fast neutron environment. Fuel restructuring, fuel-cladding heat conduction and fission gas release are modeled to provide assessment of the temperatures. Modeling emphasis has been placed on correlations to measurable quantities from EBR-II irradiation tests and the inclusion of these correlations in a physically based computational scheme. SIEX is completely modular in construction allowing the user options for material properties and correlated models. Required code input is limited to geometric and environmental parameters, with a ``consistant`` set of material properties and correlated models provided by the code. The development of physically based correlations to model certain of the phenomana has resulted in a computer program which provides reliable estimates of thermal performance characteristics, yet requires a small amount of core storage and computer running time.

Effect of sodium pool temperature on grapple drive stem temperatures at seals in CRBRP IVTM

Description: The effect of sodium pool temperature on the grapple drive stem temperatures at the seals of the CRBRP (Clinch River Breeder Reactor Plant) IVTM (In-Vessel Transfer Machine) has been calculated. Reducing the sodium pool temperature from 500 to 400/sup 0/F reduces the maximum grapple drive stem temperature at the seals from 510 to 472/sup 0/F on the initial up-stroke, and from 285 to 225/sup 0/F when system is at dynamic thermal equilibrium. The time the stem can remain in lowered position without stem temperature exceeding 300/sup 0/F at seals when stem is raised, increases from 4 minutes to 20 minutes, (the system being initially at dynamic thermal equilibrium).

Sodium technology: 1-FFTF support work, friction tests

Description: The objective of this program is to conduct friction screening tests in an environment of high-temperature, high-purity liquid sodium or sodium vapor to: (1) develop backup materials, processes, and vendors for core component wear pads, (2) investigate material treatments and coatings for improvement of wear behavior of common LMFBR structural materials, (3) evaluate weld-deposited hardfacings and/or prefabricated bearing materials for use in long-term, high-temperature, high-fluence regions, (4) evaluate bearing materials with a low potential for change in surface composition due to corrosion or mass transfer effects, and (5) develop statistical confidence in friction values for selected material combinations.

Operational safety report for the cleaning of non-radioactive, sodium-wetted reactor components with ethyl alcohol

Description: The safety aspects of the removal of sodium from nonradioactive reactor components by the alcohol process are described in detail. Pertinent properties of alcohol and hydrogen are presented. Relevant excerpts from the Occupational Safety and Health Act safety codes are presented, and a conceptual system is shown illustrating the application of these safety measures.

Analysis of environmental samples from the Mound Lab. area. Progress report

Description: All of the available analytical results from the 8 sediment cores and 16 water samples obtained from water bodies in the vicinity of Mound Laboratory during July 1974, are reported here. These include /sup 238/Pu in both sediment and water, /sup 241/Am in sediment and /sup 3/H in water. The quality of these analyses was found to be acceptable with the exception of an approximately 30% bias in the accuracy of the /sup 238/Pu data.

Effect of graded doses of ionizing radiation on the human testis. [X rays]

Description: Sixty-seven human subjects with normal testicular function were subjected to acute testicular irradiation in doses ranging from 8R to 600 R. Post irradiation observations included sperm counts and morphology, and radioimmunoassays for levels of reproductive steroids and hormones in urine (later plasma). Preliminary results and irradiation procedures are tabulated. An overview and analysis of results to date is published in a separate communication. (ERB)

Core-loading diagrams for EBR-II runs 51-67 (August 1971--December 1973). EBR-II Project

Description: The core-loading diagrams for EBR-II runs 51 through 67, which were made in EBR-II between August 1971 and December 1973 are presented. During those runs, the reactor accumulated 25,679 MWd of operation. (The reactor had been operated for an additional 46,863 MWd in runs 1-50, made between August 1964 and August 1971.) The loading diagrams appear in numerical, and thus chronological, order. Locations of experiments are highlighted in each diagram through the use of a black background behind the identifying numbers of the experiments. The center of the core is identified in each diagram by a circle, and the core sectors are identified by the letters A through F around the perimeter of the core diagram. A table at the end of the report summarizes the pertinent information for every EBR-II run through run 67. (auth)

Applications of a revived Euler--Shohat Perturbation expansion technique in the study of ocean circulation. [Coastal waters]

Description: Consideration of geophysical vertical plane flows in estuaries and on continental shelves results in nonlinearly coupled partial differential equations for flow and density variables. For the case of steady flow, the equations are reduced to ordinary differential equations by the use of similarity transformations. The remaining nonlinearly coupled ordinary differential equations are solved using a revised Euler-Shohat perturbation technique. An existence theorem for this application of the technique is stated and proved.
