SEMIANNUAL RADI0 ACTIVE EFFLUENT RELEASE REPORT ADDEN0tM FACILITY: River Bend Station,- Unit 1 LICENSEE: Gulf States Utilities Company REPORT PERIOD: October 31, 1985 through December 31, 1985 This addendum is submitted under River Bend Station (RBS) License Number NPF-47 and provides information that was not yet available while the Quarter 3/4 1985 RBS Semiannual Radioactive Effluent Release Report was being compiled. Specifically, this addendum provides information on Sr-89 and 5 -90 Gaseous Effluent Releases (pages 19 and 22 of original report); and Sr-89, Sr-90 and Fe-55 Liquid Effluent Releases (page 26 of original report) obtained from vendor-performed analyses of quarterly composite samples. It should be noted that an entry of "0.00E + 00" Ci in the following tables does not indicate the absence of a radionuclide; but, rather, indicates that the concentration of the particular radionuclide was below the Lower Limit of Detection (LLD).
