Mass flowrate measurement through gamma transmission-correlation processing

Description: On-line mass flow measurement under environmental conditions which preclude use of conventional equipment has to rely on concurrent measurements of medium density and flow velocity together with on-line computation of the mass flowrate from this information. Several types of sensors, deployed in an upstream/downstream pair, appear suitable for velocity determination through correlation. Density measurement is at present practically limited to gamma transmission. An accurate density measurement … more

Mn$sup 56$ COINCIDENCE COUNTING FACILITY

Description: A two-stage absolute counting facility for large liquid samples of aqueous Mn/sup 56/SO/sub 4/, primarily intended for better than 1% precision measurements of neutron source strengths by the manganese bath technique, is described. Two-liter samples are counted in a gamma - gamma coincidence arrangement that greatly improves long-term reproducibility at some sacrifice in counting statistics; this sacrifice is, however, lessened through a novel pulse- distribution scheme that allows fall utiliza… more

Solids Flow Rate Measurement in Dense Slurries

Description: Accurate and rapid flow rate measurement of solids in dense slurries remains an unsolved technical problem, with important industrial applications in chemical processing plants and long-distance solids conveyance. In a hostile two-phase medium, such a measurement calls for two independent parameter determinations, both by non-intrusive means. Typically, dense slurries tend to flow in laminar, non-Newtonian mode, eliminating most conventional means that usually rely on calibration (which becomes… more

Breeding rate measurements in solid fusion blankets with metallic lithium samples

Description: Measurement of the local breeding rate in a large assembly of fusion blanket candidate materials, irradiated by a fusion neutron source, serves the dual purpose of blanket design support and, perhaps more importantly, calculational method and cross section library testing. In this report, we present technical details of a measurement scheme based on deployment of encapsulated lithium metal samples and subsequent thermal digestion of the samples in a metered carrier hydrogen stream, conversion t… more

A Wide-Range Neutron Detector and Monitoring Instrument : Final Report

Description: This is the final report on the progress, "A Wide-Range Neutron Detector and Monitoring Instrument," ARF 1118-6. This report covers activities from May 8, 1958 to May 8, 1959. This report describes the basic design principles of a proportional counter that has been constructed whose cathode diameter increases towards one end.

Particle velocity and solid volume fraction measurements with a new capacitive flowmeter at the Solid/Gas Flow Test Facility. [Glass beads]

Description: The performance of a new capacitive flowmeter has been assessed experimentally in a gas-entrained solid flow stream at the Argonne National Laboratory (ANL) Solid/Gas Flow Test Facility (S/GFTF) for solid feedrates in the range of 0.5 to 2 kg/s and solid-gas loadings up to 22, corresponding to a range of solid volume fractions extending from 0.004 to 0.016. Two types of nonintrusive instruments using the capacitive principle were fabricated at ANL and installed in the horizontal leg of a 12.3 m… more

Blanket technology experiments at Argonne National Laboratory

Description: Argonne National Laboratory has the largest US program for the development of blanket technology. The goals of the program are to resolve critical issues for different blanket concepts, to develop the understanding and predictive capability of blanket behavior, and to develop the technology needed to build and operate advanced fusion blankets. The projects within the program are liquid metal MHD, breeder neutronics, tritium oxidation, transient electromagnetics, FLIBE chemistry, and insulator c… more

Neutron induced gamma spectrometry for on-line compositional analysis in coal conversion and fluidized-bed combustion plants

Description: Nuclear techniques involving relatively penetrating radiation may offer the possibility of non-invasive, continuous on-line instrumental monitoring which is representative of the full process stream. Prompt gamma rays following neutron capture are particularly attractive because the penetrating power of the neutrons and the, typically several MeV, capture gammas makes possible interrogation of material within a pipe. We are evaluating neutron capture gamma techniques for this application, both … more
