Radioiodine source and other radionuclide effluent measurements at nuclear power plants. Progress report

Comprehensive measurements are being performed within nuclear power plants (three Boiling Water Reactors, BWRs, and four Pressurized Water Reactors, PWRs) to collect radioiodine and other radionuclide data as part of a research project to develop information and test models on emission sources and transport mechanisms to permit greater accuracy in predicting the fate of radioiodine materials within nuclear power plants. This report, on project RP 274-1, contains data accumulated for the period April through August 1975 from the following three BWRs: Oyster Creek (640 MW(e) BWR2-Mark 1), Monticello (545 MW(e), BWR3-Mark 1), and Vermont Yankee (540 MW(e), BWR4-Mark 1). Sampling began in August 1974 and will be completed in December 1975 for the BWRs. PWR measurements have started at the Ginna and the Three Mile Island Nuclear Power Plants, and the third and fourth plants are in the process of being selected. The PWR measurements will be completed early in 1977. (GRA)
