Title: Joint HVDC Agricultural Study : Annual Progress Report for the 1985 Study Period.

Abstract

This report describes the first year of a 3-year study designed to assess the possible environmental effects of a +-500-kV dc transmission line. This first annual report documents site development, initiation of the livestock and crop studies, and the integration and interfacing of the agricultural and BPA's electrical monitoring study. The overall objective is to assess whether operation of a +-500-kV dc transmission line results in any detectable effects (beneficial or adverse) on plants or livestock, under controlled, simulated farming and ranching conditions. These two biological systems were selected because they can be expected to experience long-term exposure to maximum field and ion concentrations on the transmission right-of-way. This study is designed to provide data on end points and parameters of primary interest in commercial farming and ranching operations.

  • This final project report describes a 3-year study in central Oregon, conducted to assess the possible environmental effects of a +-500-kV d-c transmission line. The study, which involved beef cattle and crops, was conducted by Oregon State University (OSU) through an intergovernmental agreement with BPA. The Grizzly Mt. Facility was established by the BPA because few studies have been done for d-c transmission lines. In addition, when the Pacific Intertie was upgraded to +-500-kV in February 1985, it became the first commercial +-500 d-c line in North America. No adverse biological effects associated with the electrical properties of the Pacificmore » d-c Intertie line were documented during the 15 years the line operated at +-400-kV. Although no such effects were expected at the higher operating voltage, data from the Grizzly Mt. Facility would be used to evaluate this expectation.« less
  • A 3-year long study was conducted in central Oregon to determine the possible effects of a +-500-kV d-c transmission line on cattle and crops. Two herds totaling 100 beef cows and 6 bulls were confined in pens beneath the d-c line. The cows were paired and the other members of the pairs were maintained in two herds in control pens 2000 ft west of the line. The management facilities under the power line were duplicated in the control area. There were no significant differences in consumption of feed, minerals or water between the line and control herds. Also, no effectsmore » were found on breeding, conception, calving, calf birth date, calving interval, average daily gain, adjusted weaning weight, cow weight, condition, carcass weight, and mortality. Differences were found between years for calf birth date, average daily gain, adjusted weaning weight, and cow weight. These differences were attributed to condition and age of the cows entering the study and their adjustment to pen confinement. 67 refs., 50 figs., 106 tabs.« less
  • The second year of the program of US-Japan collaborative testing in the HFIR and ORR has been successfully completed. Two of eight phase-I target capsules were irradiated, and postirradiation testing was begun. Two spectral-tailoring capsules, MFE-6J and -7J, were fabricated and installed in the ORR. The JEOL JEM 2000FX microscope was installed at ORNL and is now being operated routinely. Microstructural data of the JPCA in the SA, 10%, and 20% cold-worked conditions and type J316 in the SA and 20% cold-worked conditions reveal that all specimens examined clearly show a high concentration of fine helium bubbles after irradiation tomore » about 30 dpa at 300/sup 0/C (in HFIR). Precipitation of MC was observed in 20% cold-worked JPCA. Swelling of all specimens was less than 1%.« less
  • Separate abstracts were prepared for nine of the included sections. (MOW)
  • The report is divided into the following: structural characterization, high-temperature alloy research, structural ceramics, radiation effects, structure and properties of surfaces and interfaces, and collaborative research centers. (DLC)
