NUREG/CR-2907 Radioactive Effluents from Nuclear Power Plants

  • Oak Ridge Associated Universities (ORAU) extract data from the ARERRs
  • ORAU prepares an annual summary report for NRCs review
  • NRC staff reviews and issues the annual summary report

NUREG/CR-2907 Radioactive Effluents from Nuclear Power Plants (Contd)

- Descriptions of the radioactive effluents

- Good visual depictions of effluents via graphs and tables

- The ability for the reader to quickly compare effluents from different nuclear power plants 4
