Decontamination and decommissioning of the EBR-I complex. Topical report No. 3. NAK disposal pilot plant test

Description: Decontamination and decommissioning of the Experimental Breeder Reactor No. 1 (EBR-I) requires processing of the primary coolant, an eutectic solution of sodium and potassium (NaK), remaining in the EBR-I primary and secondary coolant systems. While developing design criteria for the NaK processing system, reasonable justification was provided for the development of a pilot test plant for field testing some of the process concepts and proposed hardware. The objective of this activity was to pro… more

Field studies of the thermal plume from the D. C. Cook submerged discharge with comparisons to hydraulic-model results

Description: The Donald C. Cook Nuclear Plant at Bridgman, Michigan, uses submerged- diffuser discharges as a means of disposing waste heat into Lake Michigan. Preliminary results of temperature surveys of the thermal plume at the D. C. Cook Plant are presented. Indications are that the spatial extent of the plume at the surface is much smaller than previous results for surface shoreline discharges, particularly in the near and intermediate portions of the plume. Comparisons of limited prototype data with h… more

Negative ion beam processes

Description: Los Alamos Scientific Laboratory fiscal year 1975 work on production of intense, very bright, negative hydrogen (H$sup -$), ion beams and conversion of a high-energy (a few hundred MeV) negative beam into a neutral beam are described. The ion source work has used a cesium charge exchange source that has produced H$sup -$ ion beams greater than or equal to 10 mA (about a factor of 10 greater than those available 1 yr ago) with a brightness of 1.4 x 10$sup 9$ A/m$sup 2$- rad$sup 2$ (about 18 time… more

Improved techniques for the analysis of experiments with polarized targets. [1 to 2 GeV/c, polarization]

Description: An experiment was performed at the Bevatron to measure the polarization in the reaction ..pi../sup -/p ..-->.. ..pi../sup 0/n from a polarized target, at beam momenta between 1 and 2 GeV/c. Concentration is placed on the original aspects of our analysis, in particular: the geometrical reconstruction of the elastic events; the use of the high analyzing power of the reaction studied to probe the polarization of the target in magnitude and distribution; a study of the statistical estimation of the… more

Cluster carburizing. Progress report, June 1, 1975--May 31, 1976. [Ta--Hf]

Description: The Ta--Hf phase diagram was found to be sensitive to carbon content, even at levels low enough to prevent carbide formation. The ..beta../..cap alpha.. solvus at 1200/sup 0/C went from 27 to 7 percent Hf as the soluble carbon concentration increased. This effect was seen in aged and carburized samples. Just below the carbide-containing subscale, the dissolved C concentration was greater than in the bulk sample and correspondingly the amount of ..cap alpha.. phase there was greater. The hardnes… more

SIMPLEX, a code for the solution of linear programming problems

Description: A set of procedures is described for solution of a general linear programming problem that seeks to maximize the linear functional W =/sup n/ $Sigma$/sub j = 1/ c/sub j/x/ sub j/ for coordinates x/sub j/ greater than or equal to 0, subject to m restrictions of the form/sup n/$Sigma$/sub j = 1/ a/sub ij/x/sub j/ less than or equal to b/sub i/ and l restrictions of the form/sup n/ $Sigma$/sub j = 1/ a/sub ij/x/sub j/ = b/sub i/. An LRLTRAN computer code, which performs the maximization, has been … more

Report on the methylmercury situation in Par Pond. Final report

Description: Studies are reported on the methylation and accumulation of mercury in fish populations of the pond. Results showed that the majority of the mercury in the fish muscles was in the methyl mercury form. Very low concentrations of mercury were found in the pond sediments. Physiological methylation of the mercury could not be demonstrated by in vivo or in vitro techniques. Organic ligand methylation and reduction of the mercury was shown to be a possible mechanism to account for both the mercury di… more

Small-leak behavior: summary report on scoping tests. [LMFBR]

Description: A scoping phase has been completed on a study of small steam leaks in Liquid Metal Fast Breeder Reactor steam generators. Methods were developed to fabricate leaks in the size range of 10/sup -10/ to 10/sup -5/ lb/sec H/sub 2/O in 2 1/4 Cr-1 Mo steam generator tubing of prototypic wall thickness (approx. 0.110 inch). A test system was modified to supply flowing superheated steam at 1525 psig to as many as three specimens immersed in flowing sodium. Test results are presented.

Generation of short optical pulses for laser fusion. M. L. report No. 2451

Description: This report considers some of the problems involved in generating the required short pulses for the laser-fusion program. Short pulses are required to produce the laser fusion, and pulses produced synchronously with this primary pulse are required for plasma diagnostics. The requirements of these pulses are first described. Several methods are considered in order to generate pulses at 1.064 ..mu.. to drive the Nd:Glass amplifiers to produce laser fusion. Conditions for optimum energy extraction… more

Considerations in the assessment of the consequences of effluents from mixed oxide fuel fabrication plants

Description: The purpose of this study was to provide information and identify parameters relevant to assessing the consequences to man and his environment of large scale mixed plutonium-uranium oxide fuel fabrication plants which will be needed in the next 10 to 15 years. The report identifies the pertinent parameters, values, factors and methods which may be used in evaluating the environmental consequences of routine plant operation as well as postulated accidents. This study provides a base for the deve… more
