Startup and Initial Testing of SM-1 Core II With Special Components (open access)

Startup and Initial Testing of SM-1 Core II With Special Components

The loading operation for SM-1 Core II is described. Results of startup physics measurements (Test A-300 (Series) and fission product iodine monitoring in the primary coolant are given. The SM-1 Core II initial loading progressed satisfactorily, fulfilling the predictions of the zero power experiment performed at the Alco Criticality Facility. The initial cold clean five rod bank position was 6.53 in.; the initial hot, no xenon, five rod bank position was 9.62 in.; the initial hot, equilibrium xenon, five rod bank position was 11.41 in.; and the initial hot, peak xenon, five rod bank position was 12.14 in. Rods A and B were 19.00 in. in all four measurements. Stuck rod measurements indicated that an adequate shutdown margin was available with 20% of the rods fully withdrawn. All rod calibrations indicated a distinct shift and broadening of the peaks when compared with similar Core I calibrations. The temperature coefficient for Core II was 3.5 cents/ deg F at 440 deg F. Equilibrium xenon was worth approximately - 00 while peak xenon was worth - 43, both relative to the hot, no xenon core condition. During the period June 2, 1961 through September 30, 1961, the reactor operated at a total …

Potential for efficient frequency conversion at high average power using solid state nonlinear optical materials (open access)

Potential for efficient frequency conversion at high average power using solid state nonlinear optical materials

High-average-power frequency conversion using solid state nonlinear materials is discussed. Recent laboratory experience and new developments in design concepts show that current technology, a few tens of watts, may be extended by several orders of magnitude. For example, using KD*P, efficient doubling (>70%) of Nd:YAG at average powers approaching 100 KW is possible; and for doubling to the blue or ultraviolet regions, the average power may approach 1 MW. Configurations using segmented apertures permit essentially unlimited scaling of average power. High average power is achieved by configuring the nonlinear material as a set of thin plates with a large ratio of surface area to volume and by cooling the exposed surfaces with a flowing gas. The design and material fabrication of such a harmonic generator are well within current technology.

Inspection of the Heber binary-cycle geothermal project (open access)

Inspection of the Heber binary-cycle geothermal project

We concluded that DOE had effective management control procedures to monitor project costs and the design, construction and demonstration activities. Lessons learned from previous DOE geothermal projects were applied and technical information generated from the Heber plant will be transferred to the public and private sectors by the project participants. We also identified the following issues that concerned us: Revenue Sharing: under existing revenue sharing provisions in the Cooperative Agreement, we estimate that reimbursable revenues to DOE will range between $30.5 million and $51.6 million. DOE and the public should be reimbursed for the total contribution of $61 million because the plant, if commercialized, will primarily benefit ratepayers and stockholders of San Diego Gas and Electric Company (SDG and E); Project Office Support Contracts: Our analyses of a number of project office support contracts suggest that some of this work should be cost shared with SDG and E; in other cases, the value of the work is questionable and appears to be an unnecessary expenditure of DOE funds; and Questionable Contractor Procurement: the noncompetitive procurement of a private firm to develop an economic study of a second Heber plant appears to be unjustified and duplicates work already planned by project …

Preliminary assessment of tree mortality near F- and H-area seepage basins (open access)

Preliminary assessment of tree mortality near F- and H-area seepage basins

A preliminary assessment was conducted to evaluate factors that may have been responsible for the vegetation damage that has occurred in groundwater seeps downslope from the F- and H-area seepage basins. The factors that were considered included altered hydrology, toxicity from hazardous chemical constituents associated with seepage basin operation, and toxicity from non-hazardous constituents associated with basin operation. It was concluded that the observed damage was not likely to have resulted from altered hydrologic conditions or hazardous constituents associated with basin operation. Insufficient information is currently available to determine definitively which of the non-hazardous constituents, alone or in concert, were responsible for the observed vegetation damage. The most likely explanation, however, is that elevated Na, pH, and conductivity is outcropping seep water are responsible for tree mortality. All three of these factors will return to ambient levels over a period of several years when basin operation ceases. Faster remediation can be achieved using lime at the seep line.

A PROGRAM OF RESEARCH AND CALCULATIONS OF RESONANCE ABSORPTION. Final Report (open access)

A PROGRAM OF RESEARCH AND CALCULATIONS OF RESONANCE ABSORPTION. Final Report

A direct numerical integration of the integral equation for the average collision density in the absorber was previously suggested in a discussion of resonance absorption. The implementation of this program is considered. The method of calculation, comparison with experimental data, and the computer code developed are described. The method of integration, computation of cross sections, selection of mesh size, integration interval, outside correction, the Dancoff correction, and unresolved resonances are discussed. Resonance integrals for U/sup 235/ and Th2/sup >/s3>s/sup 2/ were calculated and compared with experiment. (M.C.G.)

[Letter from Bill McCarter to Bill Cormack, Janice Wiggins and Chris Thomason, July 28, 1995]

Photocopy of a summary letter from Bill McCarter, co-director of North Texas Institute for Educators on the Visual Arts, to Bill Cormack, Janice Wiggins and Chris Thomason. Regarding a meeting that fell on June 22, 1995, notably, the participation of Dallas ISD in future activities with the Institute. McCarter starts the letter with the proposal of a new time frame for the Institute activities, and mentions how the meeting brought up the ideas of having all-day Saturday sessions. However, McCarter expresses his concern that some teachers from the Dallas ISD might be unable to attend all-day Saturday sessions, and how important it is that they will attend all the meetings because of how complex the Institute is. Included in the letter is an observation from Chad Woolery, stating that due to budget and time that Dallas would be unable to continue participation with NTIEVA as a consortium member. McCarter addresses that they have had issues with Dallas since they began to participate.
