Streak camera time fiducial. Progress report, October--December 1975

doi:10.2172/7282786

Abstract

Short duration, single pulse, light sources are used to generate time fiducial marks on streak camera records. Previously, a light pulse was transmitted directly to the streak camera slit plate by a fiber optic cable whose emitting end was attached flush to the slit plate. Time resolution on the streak record was improved by positioning the emitting end of the cable back from the slit plate and collimating the light with a small diameter lens.

Heath, G R January 1976

Continued work on field data and cores from study are MPG-2 (33/sup 0/20'N, 151/sup 0/00'W) has shown that sediments are being laid down over the entire region, but that the rate of deposition in depressions is up to 70 percent greater than the rate on ridge tops. The relative fractionation has generally been constant for more than 30 million years, leading to a high degree of confidence in the predictability of the geologic future of the region, and implying that singular events and climatic changes have little effect on patterns of deposition. Continued monitoring of manganese nodule compositions has failedmore »« less

Advanced geothermal primary heat exchanger (APEX). Quarterly progress report Q-2, 1 October 1975-31 December 1975

Addoms, J.F. January 1975

The APEX program is designed to investigate the concept that a continuously recirculating flow of fine solid particles in the brine stream will substantially retard the formation of scale in the primary heat exchanger. The primary technical effort during this reporting period has been the buildup of the test facility. Some preliminary testing has been conducted in order to establish process equipment suitability prior to completing the test facility design. Fouling experiments have also been conducted in the chemistry laboratory to preliminarily screen candidate geothermal fluid simulants. (MHR)

Study of droplet hydrodynamics important in LOCA reflood. Quarterly progress report, October 1, 1975--December 31, 1975. [PWR and BWR]

Lee, R.S.L. ; Azbel, D.S. June 1976

The purpose of the theoretical and experimental research work is to investigate the fluid mechanical and heat transfer phenomena that are believed to occur during the reflood portion of the hypothesized LOCA. Particular emphasis is placed on the fluid mechanical aspects, and the fluid mechanical phenomena believed to occur in the reflood portion of the LOCA are simulated using a solid particle/air two-phase flow. For this experimental flow system, a technique is described in which the SUNY Stony Brook Laser Doppler Velocimeter (LDV) is used in conjunction with suitable electronic circuitry to obtain information on the particle size number densitiesmore »« less
