A review of selected portions of the ARHCO waste tank farm monitoring methods and systems was made. Only preliminary evaluations were made as the study was carried out over a period of only ten days. The study was requested by the Operation Support Engineering Department of ARHCO and the objectives as developed were divided into four tasks. Briefly, these were: evaluation of the waste tank dry well monitoring and data processing systems; evaluation of the accuracy (and precision) of material balance calculations for transfers from one tank to another tank; evaluation of the capabilities of material balance techniques for the detection of leaks in evaporator bottoms loop systems; and evaluation of the general operability of liquid level instrument systems currently in use and alternatives to these systems. The objectives of these tasks are restated in more detail in each of the sections below. An overview of the entire Hanford radioactive waste program including a limited description of the physical equipment involved can be found in PWM-530, Hanford Radioactive Waste Management Plans. Additional efforts have been initiated to establish an overall R and D program to more fully evaluate these systems and other factors relative to the successful operation of the …

From introduction and summary: This report is the latest in a series of investment cost studies performed for the AEC covering detailed cost and unit quantities.

A high-specific-energy lithium/sulfur battery having the performance characteristics required for powering pollutionfree automobiles is described. The cells currently under development have negative electrodes of molten lithium and positive electrodes of sulfur (plus an additive to reduce the sulfur vapor pressure) separated by a molten lithium halide-containing electrolyte. The operating temperature of the cells is about 400 deg C. The performance goals for a single cell include a capacity density of 0.4 A-hr/cm/sup 2/ at a current density of 0.1 A/cm/sup 2/, a peak power density of 1-2 W/cm/sup 2/, and a minimum cycle life of 1000 cycles. Cells with positive electrodes consisting of sulfurarsenic-carbon mixtures in graphite housings have achieved short-time peak power densities and capacity densities that meet or exceed the goals for a single cell. A capacity density of 0.1 A-hr/cm/sup 2/ has been sustained at a discharge current density of 0.1 A/cm/sup 2/l (1-V cutoff) for more than 500 hr and 100 cycles. Improvement in cell design is needed, however, to achieve higher sulfur utilization and longer cell lifetimes. (auth)

Results have been obtained from initial experiments designed to study high-voltage breakdown under conditions of importance to the design of direct- collection units. A coaxial configuration was used to mock-up critical fields near grid wires. With appropriate heat conditioning, fields as high as 9.6 x 10/ sup 5/ V/cm were maintained at the surface of a 7-mil-diam tungsten wire. This represents an enhanced field of ~10/sup 8/V/cm at whisker'' sites. Breakdown criteria are proposed for three regimes; initial, field-emission, and ultimate, which differ by the amount of prior conditioning applied to the wire. Additional considerations of importance to direct collectors such as the effect of thermionic emission and ion bombardment are discussed. (auth)

Several methods of evaluating user programs are analyzed with respect to space and time requirements. The concept of an ideal'' directly executed language is introduced, and it is argued that the ideal'' directly executed language for a contemporary computing system will not be either its source language or the language accepted by its base machine.

Microstructural and mechanical property observations of ingotsource beryllium at selected points in the can-rolling process are reported. Recrystallization occur s concurrently with rolling at temperatures above 1800 deg F, and only partial recrystallization is observed during reheats at 1400 deg F. Most grain refinement induced by the rolling schedule occurs in the first 15 rolling passes. These represent 88 percent reduction from the ingot. A relatively small contribution comes from the final six passes which bring the total reduction from the ingot to 95 percent. Information was also obtained on the effects of the rolling schedule on the properties of the stainless steel can. (auth)

Materials studies include irradiation and analysis of fuel particles in capsules to evaluate fuel systems, and basic studies of control materials and of carbon and graphite. Experimental procedures and results are discussed and, where appropriate, the data are presented. (auth)

PPO is the acronym for Pure Plutoniunn Oxide. The thermal energy of this fuel results from the radioactive decay of /sup 238/ Pu this energy is converted into usable electric power for space probe or other applications. The basic fuel module associated with the current MHW heat source is a PPO sphere 1.465 plus or minus 0.015 in. in dia and containing 100 plus or minus 2 thermal watts. The spheres are individually encapsulated and then assembled into geometric arrays to form the working heat source. The following document lists certain properties of PuO/sub 2/ with emphasis on behavior at the proposed operational conditions being discussed. Since many of the desired properties are still being determined, the information is preliminary in nature and will be revised periodically. This report is the first revision of LA-5160-MS (issued 2/ 73) and incorporates additional and more specific data. (auth)

Heat soak periods were completed on four of the ten sets of compatibility couples which were put on test during the previous quarter. The four sets contain a total of 18 couples. Four couples were examined, and tests on the others are in progress. Examination of the Kilowatt Test Source capsule was completed. Four Cm/sup 203/ceramic couples were examined and additional tests are underway. Materials selection and test conditions were finalized for a 15-couple matrix to be initinted during FY 1974. Free energy calculations were made for the reactions of Cm/sub 2/O/sub 3/ with Pt-26% Rh- 8% W, T- 111, Hafnalloy 20-20, stainless steel type 316, Ir-2% W, Pt-30% Rh- 8% W, and carbon. The cquipment assemblies for the helium release, emissivity, vapor pressure, and heat capacity experiments were completed and checked out. A comparison of physical stability was made between two essentially identical Cm/sub 2/O/sub 3/ pellets, one stored in dry air and one stored in argon. Some degradation of the air-stored pellet was noted but there was no observable change in the pellet stored in argon. Measurements of rnte-of-loss of /sup 244/Cm from s of conditions-fresh air-saturated flowing seawater at ambient temperature and a fixed volume of boiling …

The case of a noninteracting infinite Bose gas at zero temperature is studied in the formalism of local current algebras, using the representation theory of nuclear Lie groups. The class of representations describing such a system is obtained by taking an N/V limit'' of the finite case. These representations can also be determined uniquely from the solutions of a functional differential equation, which follows in turn from a condition on the ground state vector. Finally a system of functional differential equations is formulated for a theory with interactions, using a proposed definition of indefinite functional integration. (auth)

A batch supervisor for a minicomputer has been written which provides rapid sequencinig between jobs. The supervisor can handle a small number of system programs, and also allows each system program to have a large number of overlays. Overlays are read into core rapidly, and the sequencing of overlays and job steps is very flexible. Finally, the supervisor is small, leaving most of the minicomputer's core storage to the system programs. (auth)
