Demonstration of innovative applicatiions of technology for cost reductions to the CT-121 FGD process
The objective of this project is to demonstrate on a commercial scale several innovative applications of cost-reducing technology to the Chiyoda Thoroughbred-121 (CT-121) process. CT-121 is a second generation flue gas desulfurization (FGD) process which is considered by the Electric Power Research Institute (EPRI) and Southern Company Services (SCS) to be one of the most reliable and lowest cost FGD options for high-sulfur coal-fired utility boiler applications. Demonstrations of the innovative design approaches will further reduce the cost and provide a clear advantage to CT121 relative to competing technology.

Beam and viewing dump positioning inside TFTR for CTS alpha-particle diagnostics
A collective Thomson scattering (CTS) diagnostic system for localized measurement of energetic ions is being developed for TFTR. This system will use a 200KW, 56GHz gyrotron and a sensitive heterodyne receiver. In addition, a key element of this system will be beam and viewing dumps which are needed to minimize detection of stray gyrotron and ECE background radiation by the receiver system. It is the purpose of this study to determine the size and location of these dumps inside TFTR taking into account beam refraction and launch and receiver antenna optics scanning. The beam dump must cover all the area in the vacuum chamber where the beam is expected to impinge, and the viewing dump must cover all the areas within the direct line of sight of the receiver antenna. The beam launch system and the receiver antenna are to be placed nearly symmetrically above and below the midplane of the tokamak vacuum vessel, respectively. The beam dump is to be placed at the bottom inside of the vacuum vessel to absorb the gyrotron beam which will be launched from a top port. The viewing dump is expected to be placed symmetrically at the top inside of the vacuum vessel, …

Studies of human mutation rates
The three objectives of the program are: To isolate by the technique of two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), proteins of special interest because of the relative mutability of the corresponding gene, establish the identity of the protein, and, for selected proteins, move to a characterization of the corresponding gene; To develop a more efficient approach, based on 2-D PAGE, for the detection of variants in DNA, with special reference to the identification of a variant in a child not present in either parent of the child (i.e., a mutation); and, To continue an effective interface with the genetic studies on the children of atomic bomb survivors in Japan, with reference to both the planning and implementation of new studies at the molecular level. For administrative purposes, the program is subdivided into four sections, each under the direction of one of the four co-PIs; the progress during the past year will be summarized in accordance with this sectional structure. 1 tab.

Integrated dry NO sub x /SO sub 2 emissions control system
This project's goal is to demonstrate the removal up to 70% of the NO{sub x} and 70% of the SO{sub 2} emissions from coal fired utility boilers. It will establish an alternative emissions control technology integrating a combination of several processes, while minimizing capital expenditures and limiting waste production to dry solids that are handled with conventional ash removal equipment. These processes include low-NO{sub x} burners, NO{sub x} ports and urea injection for NO{sub x} control, sodium or calcium based sorbent injection for SO{sub 2} control, and flue gas humidification to enhance the reactivity of the SO{sub 2} control compound.

The limnology of L Lake: Results of the L-Lake monitoring program, 1986--1989
L Lake was constructed in 1985 on the upper regions of Steel Creek, SRS to mitigate the heated effluents from L Reactor. In addition to the NPDES permit specifications (Outfall L-007) for the L-Reactor outfall, DOE-SR executed an agreement with the South Carolina Department of Health and Environmental Control (SCDHEC), that thermal effluents from L-Reactor will not substantially alter ecosystem components in the approximate lower half of L Lake. This region should be inhabited by Balanced (Indigenous) Biological Communities (BBCs) in accordance with Section 316(a) of the Pollution Control (Clean Water) Act (Public Law 92-500). In response to this requirement the Environmental Sciences Section/Ecology Group initiated a comprehensive biomonitoring program which documented the development of BBCs in L Lake from January 1986 through December 1989. This report summarizes the principal results of the program with regards to BBC compliance issues and community succession in L Lake. The results are divided into six sections: water quality, macronutrients, and phytoplankton, aquatic macrophytes, zooplankton, benthic macroinvertebrates, fish, and community succession. One of the prime goals of the program was to detect potential reactor impacts on L Lake.

Development and demonstration of the use of modular thermo-mechanical pulpmill simulation models to develop energy reduction strategies
The Institute of Paper Science and Technology (IPST) has received a project grant from the US DOE to develop and demonstrate the use of realtime process simulation modeling as a means of process analysis and optimization. The Project, to be conducted under the auspices of the International Energy Agency (IEA), will target a Thermo-Mechanical Pulping (TMP) operation as the site for the commercial implementation of the technology. IPST and a sub-contractor, SACDA Inc. (SACDA), will cooperate in a two-to-three year effort to produce an on-line simulation program having both steady-state and dynamic modeling capabilities. The Project will take advantage of a current IPST and SACDA joint development effort to merge the IPST's MAPPS (Modular Analysis of Pulp and Paper Systems) program with SACD's MASSBAL program. Using the combined proprietary programs, realtime'' steady-state and dynamic TMP models will be developed and installed as part of a millwide'' information/analysis system. By utilizing the Performance Attribute (PAT) Modeling concept developed at IPST, the models will have the capability of optimizing energy usage and other process operating variables as a function of pulp quality. The primary goal of the Project is to demonstrate that on-line simulation models can provide assistance to operators and managers …

The U5. 0 Undulator for the ALS
the U5.0 Undulator, and 89 period, 5 cm period length, 4.6 m long insertion device has been designed, is being fabricated and is scheduled for completion in early 1992. This undulator will be the first high brightness source, in the 50 to 1500 eV range, for the Advanced Light Source (ALS) at the Lawrence Berkeley Laboratory. A hybrid magnetic configuration using Nd-Fe-B permanent magnet material and vanadium permendur poles has been selected to achieve the field quality needed to meet performance requirements. The magnetic structure is modular with each half consisting of 5 assembly sections, which provide the periodic structure, and end structures, for entrance and exit correction, mounted on a steel backing beam. Each assembly section consists of 35 half-period pole assemblies bolted to a mount. The required 0.837 Tesla effective peak field at a 1.4 cm gap has been verified with model measurements. Vertical field integral correction is accomplished with the end structures, each having an arrangement of permanent magnet rotors which will be adjusted to minimize electron beam missteering over the undulator operating field range. To reduce the effect of environmental fields, the steel backing beams are connected through parallel, low-reluctance, Ni-Fe hinges. The magnetic structure is …
