Reactions and moderators for an accelerator-based epithermal neutron capture therapy source for cancer treatment. Final report, October 1900--September 1994

Description: The use of boron neutron capture therapy (BNCT) has been considered for nearly 30 years, and been practiced in Japan since the late 1970`s. Early experiments in the USA were generally nonpromising. However, new boron-containing ligand compounds were developed, which would seek out brain tumors. Concentration levels of the order of 30 micrograms of boron per gram of tissue become possible, and interest in the BNCT technique was revived in the USA beginning about 1985, with research reactors as the obvious source of the neutrons for the treatment. However, the limited number of research reactors in the USA (and the world) would mean that this treatment modality would be quite limited. The goals of this work was: (1) Examine as many as possible reactions of charged particles on various targets of an accelerator, and determine those that would give high neutron yields of a convenient energy. (2) Determine, through calculations (using Monte Carlo stochastic computer codes), the best design for a moderator/reflector assembly which would give high thermal flux at a nominal 5 cm depth in the head of a patient, with minimal radiation dose from gamma rays and fast neutrons. (3) Perform a benchmark experiment using a positive ion accelerator. The Li-7(p,n) reaction was chosen for the benchmark, since it was readily available for most accelerators, and was one of the two highest yielding reactions from Task No. 1. Since the University of Missouri has no accelerator, possible accelerators at other universities were investigated, as to availability and cost. A unit having capability in the 2.5 MeV range was desired.

Geothermal Exploratory-Well Project: city of Alamosa, Colorado. Final report, September 1980-April 1983

Description: The Geothermal Exploratory Well Project for the City of Alamosa, Colorado is summarized. In September, 1980, the City of Alamosa made application to the US Department of Energy for a program which, in essence, provided for the Department of Energy to insure that the City would not risk more than 10% of the total cost in the well if the well was a failure. If the well was a complete success, such as 650 gpm and 230/sup 0/F temperature, the City was responsible for 80% of the costs for drilling the well and there would be no further obligation from the Department of Energy. The well was drilled in November and early December, 1981, and remedial work was done in May and June 1982. The total drilled depth was 7118 ft. The well was cased to 4182 ft., with a slotted liner to 6084 ft. The maximum down hole temperature recorded was 190/sup 0/F at 6294 ft. Testing immediately following the remedial work indicated the well had virtually no potential to produce water.

Industrial food processing and space heating with geothermal heat. Final report, February 16, 1979-August 31, 1982

Description: A competitive aware for a cost sharing program was made to Madison County, Idaho to share in a program to develop moderate-to-low temperature geothermal energy for the heating of a large junior college, business building, public shcools and other large buildings in Rexburg, Idaho. A 3943 ft deep well was drilled at the edge of Rexburg in a region that had been probed by some shallower test holes. Temperatures measured near the 4000 ft depth were far below what was expected or needed, and drilling was abandoned at that depth. In 1981 attempts were made to restrict downward circulation into the well, but the results of this effort yielded no higher temperatures. The well is a prolific producer of 70/sup 0/F water, and could be used as a domestic water well.

Floral greenhouse heating. Semi-annual technical report

Description: A demonstration project for providing floral greenhouse space/process heat for a 6-acre greenhouse facility in metropolitan Salt Lake City has been jointly undertaken by the greenhouse owner (Utah Roses, Inc.) and the US Department of Energy. The work on the environmental evaluation was completed in March 1979, and the contract between the two principal organizations to proceed with the project was signed on May 1. Drilling of the first well is scheduled to commence by late October, with a target drilling depth of 3,000 to 4,000 feet. There are several shallow warm wells in the area, the closest being 100 yds from Utah Roses, and having 94/sup 0/F temperatures at 750-foot depth. A minimum target temperature of 120/sup 0/F has been set for the exploratory production well, which is to be drilled beginning in late October 1979.

Geothermal R and D project report for April 1, 1977--September 30, 1977

Description: The Idaho Geothermal Research and Development Program was initiated in 1973. The program's mission has been to improve the technology necessary to utilize geothermal fluids of moderate temperature--fluids of about 150/sup 0/C or 300/sup 0/F. This report discusses the progress from April to September 1977, during which time an injection well was drilled and the design of a 5000-kW(e) pilot power plant was completed. Manufacturers began fabricating heat exchangers and condensers for the power plant and a cooling tower to dissipate 40 MW of heat was ordered.

710 Mockup No. 1 critical experiment. Summary data report

Description: Declassified 21 Sep 1973. A summary of the experiments associated with the three uniformly loaded core configurations related to the 710 Mockup 1 Critical Experiment Reactor is presented. These configurations mocked up specific features of the then current 710 reactor experiment design. The experimental areas included initial loading, neutron lifetime, fission ratios, reflector control methods, reactivity coefficients and power distribution measurements. A major portion of the effort was applied to the latter two areas to determine the comparative effects between normally used fuel cells composed of rod-type materials and homogeneous fuel cells using fabricated fuel compacts''. 7 references.

Asbestos--cement pipeline experience at the Raft River Geothermal Project

Description: The first buried asbestos-cement (Transite) pipeline used in high temperature (approximately 300/sup 0/F) service for transport of geothermal fluids was installed in the fall of 1975, and has seen 1/sup 1///sub 2/ years of service. The line is 4000 ft long, between the deep geothermal wells No. 1 and No. 2, in the Raft River Valley of Idaho. The experience in using this pipeline has been satisfactory, and methods have been developed for minimizing the thermal expansion/thermal shock breakage problems. Recommendations on improved design and construction practices for future pipelines are given. The substantially reduced cost (factor of 2) of an asbestos-cement pipeline compared to the conventional steel pipeline, plus the esthetically desirable effect of a buried pipeline dictate adoption of this type as standard practice for moderate temperature geothermal developments. The Raft River Geothermal Project intends to connect all future wells with pipelines of asbestos-cement, insulated with 1 to 2-inches of urethane, and buried between 2 and 3 ft. Total cost will be approximately $110,000/mile for 10-inch diameter pipe, $125,000/mile for 12-inch diameter.

Space heating systems in the Northwest: energy usage and cost analysis

Description: The question of energy usage and cost of providing space heat in the Northwest is discussed. Though space heating needs represents only 18% of the U.S.'s total energy consumption, it nevertheless appears to offer the greatest potential for conservation and near term applications of alternate energy sources. Efficiency and economic feasibility factors are considered in providing for space heating demands. These criteria are presented to establish energy usage, cost effectiveness and beneficial conservation practices for space heating of residential, commercial, and industrial buildings. Four Northwestern cities have been chosen whose wide range of climate conditions are used to formulate the seasonal fuel and capital cost and hence the annual heating cost covering a broad spectrum of heating applications, both the traditional methods, the newer alternate forms of energy, and various methods to achieve more efficient utilization of all types.
