Hydrogen attack of steel. Progress report, April 1, 1978--March 31, 1979

Description: Four normalized carbon steels made in different ways (Si-killed, Al-killed, REM-treated, and electroslag refined) were studied to determine the role of differing fine inclusions on the early stages of hydrogen attack (HA). Hydrogen exposures were made at 450/sup 0/C (6.5 MPa) and 375/sup 0/C (7.6 MPa). The first stage of HA is shown to be the development of a closely spaced (1-2 ..mu..m) array of small bubbles over the ferrite/pearlite, or occasionally the ferrite/ferrite boundaries. These grew… more

A scheme to improve the low energy luminosity in LEP

Description: In the design of large electron positron colliding beam facilities, it has become customary to use a certain optimization procedure to establish desired beam performance. The results of this procedure are the minimum requirements in terms of RF-power, bending radius and focusing to achieve a desired luminosity at a given energy. This procedure, however, neglects the optimization of the storage ring performance below and above that design energy. Below the design energy the luminosity is optimiz… more

LOFT drag-disc turbine tansducer shroud and cover weld analysis and evaluation

Description: The results are presented of stress analysis and evaluation of the drag-disc turbine transducer (DTT) shroud and cover welds used in the Loss-of-Fluid Test (LOFT) facility. The analysis concerns LOFT DTTs currently installed and/or planned for use in future experiments by LOFT Experimental Measurements Branch personnel. Thermal/hydraulic conditions for Experiments L1-5 and L2-4 (for all nuclear tests) were used to predict the loads experienced by the various shroud and cover welds. The results … more

Analysis of advanced conceptual designs for single-family-sized absorption chillers. Annual report

Description: The objectives of the research reported is to develop and analyze new concepts for absorption cycles to improve the performance or reduce the cost of a 3-ton absorption chiller that can be used with solar collected heat. New refrigerant-absorbent pairs are investigated, as are additives to currently used refrigerant-absorbent pairs. Results are given of a literature search on those topics. An initial screening is reported to check the values of the heats of mixing of candidate refrigerants and … more

Evaporative removal of sodium: interim progress report and preliminary facility specification

Description: A summary of the current Evaporative Removal of Sodium (ERNA) activities at the Energy Systems Group is presented. Also included is a review of earlier work on sodium evaporation. As a result of this work it was concluded that the ERNA process was extremely successful and worthy of future consideration as a recognized process for reactor components. Also included in the report is a Preliminary Outline Specification for a large facility to remove sodium from full size CRBR fuel rod assemblies.

Preliminary investigation of two areas in New York State in terms of possible potential for hot dry rock geothermal energy. [Adirondack Mountains and Catskill Mountains]

Description: Two areas in New York State were studied in terms of possible long range potential for geothermal energy: the Adirondack Mountains which are undergoing contemporary doming, and an anomalous circular feature centered on Panther Mountain in the Catskill Mountains. The Adirondack Mountains constitute an anomalously large, domical uplift on the Appalachian foreland. The domical configuration of the area undergoing uplift, combined with subsidence at the northeastern perimeter of the dome, argues fo… more

Near-term electric-vehicle program. Phase II. Mid-term review summary report

Description: The general objective of the Near-Term Electric Vehicle Program is to confirm that, in fact, the complete spectrum of requirements placed on the automobile (e.g., safety, producibility, utility, etc.) can still be satisfied if electric power train concepts are incorporated in lieu of contemporary power train concepts, and that the resultant set of vehicle characteristics are mutually compatible, technologically achievable, and economically achievable. The focus of the approach to meeting this g… more

Revised error analysis of LOFT secondary calorimetric power equation

Description: A second-order error analysis of the LOFT secondary calorimetric power equation was performed to determine a figure for system accuracy for use in safety analysis and program evaluation. A realistic figure of accuracy for the Secondary Coolant System (SCS) was developed reflecting the relative importance of each measured parameter. This analysis was performed using SOERP, a second-order error propagation computer code. The final 2sigma tolerance band on calculated calorimetric power was found t… more
