Axicell design for the end plugs of MFTF-B

Description: Certain changes in the end-plug design in the Mirror Fusion Test Facility (MFTF-B) are described. The Laboratory (LLNL) proposes to implement these changes as soon as possible in order to construct the machine in an axicell configuration. The present physics and technology goals as well as the project cost and schedule will not be affected by these changes.

Monitoring the materials and chemistry of a geothermal plant

Description: The components of geothermal brines that cause corrosion and scaling problems are reviewed, especially brine pH, CO/sub 2/, H/sub 2/S, oxygen (from air), silicia, calcium, sulfides, and suspended particulates. Instrumental methods for on-line measurement are discussed to show how to keep costs low by operating a geothermal plant from a position of knowledge of what is occurring to the plant materials. The US Department of Energy research and development program in brine chemistry and on-line in… more

Optimization of steam explosion pretreatment. Final report

Description: Different operating conditions are required to optimize the yield from each of the various fractions in the substrate. Xylose recovery is maximized at short cooking times whereas maximum lignin recovery requires much longer cooking times. Peak glucose yield and rumen digestibility occur at intermediate times. If process conditions are set for maximum glucose yield we have achieved a yield of 68% of the theoretical, based on an average of a dozen substrates tested. Individual results ranged from… more

Preliminary requirements for thermal storage subsystems in solar thermal applications

Description: Methodologies for the analysis of value and comparing thermal storage concepts are presented. Value is a measure of worth and is determined by the cost of conventional fuel systems. Value data for thermal storage in large solar thermal electric power applications are presented. Thermal storage concepts must be compared when all are performing the same mission. A method for doing that analysis, called the ranking index, is derived. Necessary data to use the methodology are included.

Regenerative Process for Desulfurization of High Temperature Combustion and Fuel Gases. Progress Report No. 15, January 1-March 31, 1980

Description: A new regenerative sorbent process for desulfurizing fluidized-bed combustion gases is presented. The sorbent was developed by Brookhaven National Laboratory and is prepared from commercial silicate bearing portland cement. The chemical reactions and mechanical procedures involved in preparing the sorbent, in desulfurizing the flue gas, in regenerating the spent sorbent, and in producing elemental sulfur from the regenerator product gas are discussed. The performance of natural limestone sorben… more

Fusion breeder

Description: The fusion breeder is a fusion reactor designed with special blankets to maximize the transmutation by 14 MeV neutrons of uranium-238 to plutonium or thorium to uranium-233 for use as a fuel for fission reactors. Breeding fissile fuels has not been a goal of the US fusion energy program. This paper suggests it is time for a policy change to make the fusion breeder a goal of the US fusion program and the US nuclear energy program. The purpose of this paper is to suggest this policy change be mad… more

A proposal for a precision test of the standard model by neutrino-electron scattering (Large /hacek C/erenkov Detector Project)

Description: A precision measurement of neutrino-electron elastic scattering from a beam stop neutrino source at LAMPF is proposed. The total error in sin/sup 2/theta/sub W/ is estimated to be +-0.89/percent/. The experiment also will be sensitive to neutrino oscillations and supernova-neutrino bursts, and should set improved limits on the neutrino-charge radius and magnetic-dipole moment. The detector consists of a 2.5-million-gallon tank of water with approximately 14,000 photomultiplier tubes lining the … more

Safeguards instrumentation: a computer-based catalog. Second edition

Description: This catalog contains entries on new developments and on items listed in BNL 51450, which have either been carried over unchanged or been updated. More than 70 entries were deleted because of either obsolescence, insufficient interest in terms of safeguards, or lack of documentable development activities in recent years. Some old listings as well as new material was consolidated into more generic entries. As in the earlier document, the emphasis is on devices and instruments that are either in … more

Beryllium usage in fusion blankets and beryllium data needs. [None]

Description: Increasing numbers of designers are choosing beryllium for fusion reactor blankets because it, among all nonfissile materials, produces the highest number (2.5 neutron in an infinite media) of neutrons per 14-MeV incident neutron. In amounts of about 20 cm of equivalent solid density, it can be used to produce fissile material, to breed all the tritium consumed in ITER from outboard blankets only, and in designs to produce Co-60. The problem is that predictions of neutron multiplication in bery… more

ACFAC: a cash flow analysis code for estimating product price from an industrial operation

Description: A computer code is presented which uses a discountted cash flow methodology to obtain an average product price for an industtrial process. The general discounted cash flow method is discussed. Special code options include multiple treatments of interest during construction and other preoperational costs, investment tax credits, and different methods for tax depreciation of capital assets. Two options for allocating the cost of plant decommissioning are available. The FORTRAN code listing and th… more

ALARA studies on spent fuel and waste casks

Description: In this report, some implications of applying the ALARA concept to cask designs for transporting spent fuel, high-level commercial and defense waste, and remote-handled transuranic waste are investigated. The XSDRNPM, one-dimensional radiation transport code, was used to obtain potential shield designs that would yield total dose rates at 1.8 m from the cask surface of 10, 5, and 2 mrem/h. Gamma shields of depleted uranium, lead, and steel were studied. The capacity of the casks was assumed to … more

Separation of alcohol-water mixtures using salts

Description: Use of a salt (KF or Na/sub 2/SO/sub 4/) to induce phase separation of alcohol-water mixtures was investigated in three process flowsheets to compare operating and capital costs with a conventional distillation process. The process feed was the Clostridia fermentation product, composed of 98 wt % water and 2 wt % solvents (70% 1-butanol, 27% 2-propanol, and 3% ethanol). The design basis was 150 x 10/sup 6/ kg/y of solvents. Phase equilibria and tieline data were obtained from literature and exp… more

Economic implications of fusion-fission energy systems

Description: The principal conclusions that can be made based on the estimated costs reported in this paper are twofold. First, hybrid reactors operating symbiotically with conventional fission reactors are a potentially attractive supply alternative. Estimated hybrid energy system costs are slightly greater than estimated costs of the most attractive alternatives. However, given the technological, economic, and institutional uncertainties associated with future energy supply, differences of such magnitude … more

Review of petroleum transport network models and their applicability to a national refinery model

Description: This report examines four petroleum transport network models to determine whether parts of them can be incorporated into the transportation component of a national refinery model. Two questions in particular are addressed. (a) How do the models under examination represent the oil transport network, estimate link capacities, and calculate transport costs. (b) Are any of these network representations, capacity estimates, or cost functions suitable for inclusion in a linear programming model of oi… more

Development of a joint-cost allocation manual for integrated community energy systems. Phase II

Description: The distribution of Integrated Community Energy Systems (ICES) project capital and operating costs among multiple ICES services is of prime concern for an ICES owner and/or operator. The maintenance of adequate revenues from individual services and the commercial viability of an ICES project is influenced significantly by the method chosen for cost allocation. An in-depth study is presented of the Alternative Justifiable Expenditure method (AJE). The advantages and disadvantages of the AJE are … more
