Advances in the theory and modelling of pollutant-gas washout

Description: A program for evaluation of precipitation scavenging as a mechanism of removal of contaminants from power plant plumes has been in progress. This program began with field studies at the Keystone plant in Western Pennsylvania, which led to the development of new gas-washout models and related field studies at other locations. The progress of this program is described and some comparisons of measured SO/sub 2/ washout concentrations with those predicted by reversible and irreversible gas washout … more

AEC/RECON project at ORNL

Description: The present status of the AEC/RECON project is discussed, with particular reference to the ORNL participation. A little of the history of the project is given, plus some technical description and a user's manual. AEC/RECON is an information retrieval prolect that uses CRT screens for rapid display of results from computerized files. Bibliographic data from Nuclear Science Abstracts and other data bases are available for searching. The project came to ORNL in 1971 with 5 terminals and 150,000 bi… more

Aerial radiological measuring survey of the area surrounding Big Rock Point Nuclear Plant, Big Rock Point, Michigan, 1968

Description: The Aerial Radiological Measuring System (ARMS), operated for the U. S. Atomic Energy Commission, was used to perform aerial surveys of several operational and non-operational reactor sites during the summer months of 1968. The data collected on these surveys included aerial photographs of the installations, aerial radiation survey data consisting of exposure rates normalized to 3 feet above the ground plus gamma-ray spectral charts, effluent characterization for operational sites (intensity ra… more

Aerial radiological measuring survey of the area surrounding the Enrico Fermi Atomic Power Plant, Monroe, Michigan, September 1970

Description: The Aerial Radiological Measuring System (ARMS) was used to survey the Enrico Fermi Atomic Power Plant and surrounding area during Sept. 1970. The survey measured terrestrial background gamma radiation and included a plume track of the stack release gases. A high-sensitivity detection system collected gamma spectral and gross-count data. The data were then computer processed into a map of a 277 sq. mile area showing isoexposure contours 3 ft above ground. Results indicated the presence of isoto… more

Aerial radiological measuring survey of the area surrounding the La Crosse Boiling Water Reactor, Genoa, Wisconsin, July 1968

Description: The Aerial Radiological Measuring System (ARMS) was used to survey the area surrounding the La Crosse Boiling Water Reactor during July 1968. The survey measured terrestrial gamma radiation. A high-sensitivity detection system collected gamma spectral and gross-count data. The data were then computer processed into a map of a 625 sq. mile area showing isoexposure contours 3 ft above the ground. Exposure rates and isotopes identiiied are consistent with normal background radiation. (auth)

Aerial radiological measuring survey of the area surrounding the Monticello Nuclear Generating Plant, Monticello, Minnesota, August 1970

Description: The Aerial Radiological Measuring System (ARMS) was used to survey the Monticello Nuclear Generating Plant and surrounding area during Aug. 1970. The survey measured terrestrial background gamma radiation. A high-sensitivity detection system collected gamma spectral and gross-count data. The data were then computer processed into a map of a 625 sq. mile area showing isoexposure contours 3 ft above the ground. Results indicated the presence of isotopes normally found in the background radiation … more

Aerial radiological measuring survey of the area surrounding the Palisades Plant, South Haven, Michigan, July 29, 1970

Description: The Aerial Radiological Measuring System (ARMS) was used to survey the area surrounding the Palisades Plant during July 1970. A high-sensitivity detection system collected gamma spectral and gross-count data. The data were then condputer processed into a map of a 300 sq. mile area showing isoexposure contours 3 ft. above the ground. Exposure rates and isotopes identified are consistent with normal terrestrial background radiation. (auth)

Aerial radiological measuring survey of the area surrounding the Vermont Yankee Generating Station and the Yankee Nuclear Power Station, September 18, 1970

Description: The Aerial Radiological Measuring System (ARMS) was used to survey the area surrounding the Vermont Yankee Generating Station and the Yankee Nuclear Power Station during September 1970. The survey measured terrestrial gamma radiation. A high-sensitivity detection system collected spectral and grosscount data for the flyable portions of the 625 sq. mile survey area. Isotopes identified and exposure rates are consistent with normal background radiation. (auth)

Aerospace Safety Program: summary report

Description: Projects in support of the Aerospace Nuclear Safety Program are summarized. The objective of the program was to evaluate the radiological safety of SNAP systems and to develop methods and designs to assure that safety. Projects summarized are analyses and experiments for determining: (1) the disintegration of reactors reentering the atmosphere; (2) the burnup of fuel elements reentering the atmosphere, including ablation and dispersal of particles; (3) reactor criticality conditions and the ass… more

Afterheat calculations for the HTGR

Description: Afterheat rates were calculated for the HTGR utilizing new input information. The new afterheat results are a few percent higher than the HTGR afterheat results previously obtained in the 100-to 10,000-sec time range and are 11 to 15% higher than the previous results in the one-day to ten-days time range. The uncertainties were studied in the time region from 100 sec to ten days. The new results were also compared with calculations at other laboratories. The gamma-ray spectra were computed at s… more

Age estimates of stratospheric air

Description: It is shown that careful consideration of /sup 32/P//sup 7/Be ratios (both isotopes being generated in the atmosphere by cosmic radiation) not only yields information on the stratospheric or tropospheric origin of air masses. These ratios may also be used to determine the residence time in the stratosphere of tropospheric air that underwent upward transport through the tropopause and re-entered the troposphere at a later date.
