Hydraulic fracture experiments in GT-1 and GT-2

Description: Hydraulic fracturing experiments were conducted in granite rock, at temperatures near 100 and 150/sup 0/C, in two wells 0.785 km (2575 ft) and 1.98 km (6500 ft) deep near Los Alamos, New Mexico. No unusual difficulty was observed in fracturing crystalline rock hydraulically. The apparent surface energy (energy required to create new fracture surface by breaking the rock) was measured as 100 J/m/sup 2/. Orientation of the deeper fracture was measured as N35/sup 0/E (+-5/sup 0/). The fraction of … more

Biphase turbine bottoming cycle for a diesel engine

Description: Application of a two-phase turbine system to waste heat recovery was examined. Bottoming cycle efficiencies ranging from 15 to 30% were calculated for a 720/sup 0/F diesel exhaust temperature. A single stage demonstration unit, designed for non-toxic fluids (water and DowTherm A) and for atmospheric seals and bearings, had a cycle efficiency of 23%. The net output power was 276 hp at 8,100 rpm, increasing the total shaft power from 1,800 hp for the diesel alone, to 2,076 hp for the combined sys… more

Drywell pressurization test for the NRC 1/5 scale pressure suppression experiment

Description: A drywell pressurization test was conducted at LLL on February 1, 1977, as part of the NRC /sup 1///sub 5/ scale pressure suppression experiment. A series of four test runs were completed with predicted initial drywell pressurization rates of 14.0, 18.6, 23.0, and 26.0 psi/sec (96.5, 128, 159, and 179 kPa/sec). Each test run consisted of charging various combinations of bottles with nitrogen under high pressure, evacuating the drywell to /sup 1///sub 5/ atmosphere, and opening a valve between t… more

Electrochemical decontamination of strontium fluoride storage capsules

Description: Double containment in Hastelloy C-276 capsules is used. Remote filling, welding, and handling operations unavoidably contaminate the capsule surface with strontium fluoride in a form that is extremely difficult to remove. Electropolishing was investigated as an alternative surface decontamination technique for the inner storage capsule. Initial feasibility studies using contaminated dummy capsules and capsule sections demonstrated the ability of electropolishing to rapidly and effectively remov… more

Summary of calculations of dynamic response characteristics and design stress of the 1/5 scale PSE torus. [BWR; MK1 pressure suppression system]

Description: The Lawrence Livermore Laboratory is currently involved in a 1/5 scale testing program on the Mark I BWR pressure suppression system. A key element of the test setup is a pressure vessel that is a 90/sup 0/ sector of a torus. Proper performance of the 90/sup 0/ torus depends on its structural integrity and structural dynamic characteristics. It must sustain the internal pressurization of the planned tests, and its dynamic response to the transient test loads should be minimal. If the structural… more

Hydrodynamic stability of lithium flows on porous spherical surfaces

Description: Lithium flows on the inside surface of a porous spherical shell are analyzed to determine their stability characteristics against small perturbations in (1) the film thickness, (2) the colatitude component of the lithium velocity, and (3) the rate of mass supply of lithium through the porous wall. A linearized stability analysis is developed, and it is concluded that lithium film flows are stable against these types of perturbations.

User guide for computer program food. [Internal radiation doses to man from radionuclides in food products]

Description: An interactive code, FOOD, has been written in BASIC for the UNIVAC 1108 to facilitate calculation of internal radiation doses to man from radionuclides in food products. In the dose model, vegetation may be contaminated by either air or irrigation water containing radionuclides. The model considers two mechanisms for radionuclide contamination of vegetation: direct deposition of leaves, and uptake from soil through the root system. The user may select up to 14 food categories with correspondin… more

Interim design status and operational report for semiremote handling fixtures: size reduction system

Description: Crushing of HTGR fuel elements is accomplished by a three-stage crushing system consisting of two overhead eccentric jaw crushers, a double-roll crusher, and an oversize reduction system to ensure complete reduction to the desired size. The crushing system is mounted in a special framework which enables gravity flow, eliminates material transport, and minimizes material holdup. The system has been designated UNIFRAME because of the integrated nature of the equipment. This report addresses the d… more

Monte Carlo simulation using the meter system with application related to LWBR

Description: METER is a Monte Carlo computer program which can be used to simulate the interaction between independent random variables and their effects on one or more dependent random variables. The program is easy to use for simple simulations but is capable of accommodating complex simulations. METER processes input, generates random numbers from several common frequency distributions under user control, performs the simulation which the user has coded in FORTRAN, and displays results.

Analysis of past and expected future trends in U. S. energy consumption, 1947--2000

Description: In the first part of this paper, energy consumption trends to the year 2000 are estimated for 110 different industrial sectors and for household and government final demand sectors, and these trends are compared with historical 1947-to-1967 trends. For most sectors, energy consumption is expected to increase much less rapidly in the 1967-1985 period than it did in the 1947-1967 period as a result of the recent large energy price increases. Between 1985 and 2000, the rate of growth of energy con… more

Reference documents for the proposal for a national synchrotron light source

Description: The spectra, angular distribution and polarization functions of synchrotron radiation are tabulated in parametric form. Numerous graphs of the functions are included which can be used for rapid estimation of photon flux as a function of the various parameters. The extended synchrotron radiation source is described and the exact, but unintegrable, equations are derived. Properties of this source depend upon at least nine parameters. An approximation of the source accurate enough for estimating f… more

Analysis of electricity production costs from the geopressured geothermal resource

Description: The economics of the geopressured geothermal resource along the northern coast of the Gulf of Mexico is assessed. Geopressured waters are nearly under twice the normal hydrostatic pressure and believed to be saturated with methane. The costs of generating electricity from this resource are estimated based on the description and conceptual development plans provided by the United States Geological Survey (USGS). Methane content and selling prices are the most important factors affecting the comm… more
