1.0 INTRODUCTION
This Semiannual Radioactive Effluent Release Report is for Rochester Gas and Electric Corporation's R.E. Ginna plant and is submitted in accordance with the require-ments of Technical Specification Section 6.9.1.4. The report covers the period from January 1, 1989 through June 30, '1989.
This report includes a summary o f the quantities o f radioactive gaseous and liquid effluents and solid waste released from the plant presented in the format outlined in Appendix B of Regulatory Guide 1.21, Revision 1, June 1974.
All gaseous and liquid effluents discharged during this reporting period were in compliance with the limits of the R.E. Ginna Technical Specifications.
2.0 SUPPLEMENTAL INFORMATION 2.1 Re ulator Limits The Technical Specification limits applicable to release of radioactive material in liquid and gaseous effluents are:
2.1.1 Fission and Activation Gases The instantaneous dose rate, as calculated in the ODCM, due to noble gases released in gaseous effluents from the site shall be limited to a release rate which would yield
< 500 mrem/yr to the total body and < 3000 mrem/yr to the skin if allowed to continue for a full year.
The air dose, as calculated in the ODCM, due to noble gases released in gaseous effluents from the site shall be limited to the following:
(i) During any calendar quarter to < 10 mrad for gamma radiation and to < 20 mrad for beta radiation.
2 ' ~ 2 Radioiodine Tritium and Particulates The instantaneous dose rate, as calculated in the ODCMg due to radioactive materials released in gaseous effluents from the site as radioiodines, radioactive materials in particulate form, and.radionuclides other than noble gases with half-lives greater than 8 days shall be limited to a release rate which would yield <
1500 mrem/yr to any organ if allowed to continue for a full year.
t I il
The dose to an individual, as calculated in the ODCM, from radioiodine, radioactive materials in particulate form and radionuclides other than noble gases with half-lives greater than eight days released with gaseous effluents from the site shall be limited to the following:
(i) During any calendar quarter to < 7.5 mrem to any organ.
(ii) During any calendar year to < 15 mrem to any organ.
2 ' ' Li id Effluents The release of radioactive liquid effluents shall be such that the concentration in the circulating water discharge does not exceed the limits specified in accordance with Appendix B, Table II, Column 2 and notes thereto of 10CFR20. For dissolved or entrained noble gases the total activity due to dissolved or entrained'oble gases shall not exceed 2 E-04 uCi/ml.
The dose or dose commitment. to an individual as calcu-lated in the ODCM from radioactive materials in liquid effluents released to unrestricted areas shall be limited:
(i) During any calendar quarter to < 1.5 mrem to the total body and to < 5 mrem to any organ, and (ii) During anyto calendar year to < 3 mrem to the total body and < 10 mrem to any organ.
2.2 Maximum Permissible Concentrations MPC 2.2.1 For gaseous effluents, maximum permissible concentrations are not directly used in release rate calculations since the applicable limits are stated in terms of dose rate at the unrestricted area boundary.
2 ' ' For liquid effluents, the maximum permissible concen-tration values specified in 10CFR20, Appendix B, Table II, column 2 are used to calculate release rates and permissible concentrations at the unrestricted area boundary. A value of 2E-04 uCi/ml is used as the MPC for dissolved and entrained noble gases in liquid effluents.
n,k 4
2 ' Release Rate Limits The release rate limits for fission and activation gases from the R.G.&E Ginna plant are not based on the average energy of the radionuclide mixture in gaseous effluents; therefore, this value is not applicable. However, the average energy of the radionuclide mixture was 0.448 Mev.
2.4 Measurements and A roximations of Total Radioactivit Gamma spectroscopy was the primary analysis method used to determine the radionuclide composition and concen-tration of gaseous and liquid effluents. Composite samples were analyzed for Sr-89, Sr-90 and Fe-55 by a contract laboratory. Tritium and alpha analysis were done using liquid scintillation and gas flow proportional counting respectively.
The total radioactivity in effluent releases were deter-mined from the measured concentration of each radio-nuclide present in grab or composite samples and the total volume of effluents released.

SUMMARY
OF GASEOUS RADIOACTIVE EFFLUENTS The quantities of radioactive material released in gaseous effluents are summarized in Tables 1A and 1B.
The effluent release heights of the majority of releases were considered to be elevated. Gaseous effluent totals now include C-14 release quantities.
4.0
SUMMARY
OF LIQUID RADIOACTIVE EFFLUENTS The quantities of radioactive material released in liquid effluents are summarized in Tables 2A and 2B.
5.0 SOLID WASTES The quantities of radioactive material released in shipments of solid waste transported from the site during the reporting period are summarized in Table 3.
Principal nuclides were determined by gamma spectroscopy and non-gamma emitters were calculated from scaling factors determined by an independent laboratory from representative samples of that waste type.
6 ' LOWER LIMIT OF DETECTION NOT MET There were 26 liquid releases for which 1 or more gamma emitting radionuclide did not meet the required lower limit for detection. These are listed by release number in Table 4.
7.0 RADIOLOGICAL IMPACT An assessment of doses to the maximally exposed indivi-dual from gaseous and liquid effluents will be performed and reported in the July - December, 1989 Semi-Annual Report for the year of 1989.
8~0 METEOROLOGICAL DATA Not applicable for this report.
9.0 LAND USE CHANGES Not applicable for this report.
10.0 ANNUAL TABULATION OF PERSONNEL EXPOSURE This data will be in the report issued for July-December, 1989.
k

LEAK TEST OF SEALED SOURCES No sealed sources were found to be leaking when smeared by both wet and dry smears.
CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL (ODCM)
Minor typographical and wording changes as a result of a periodic review were made to the procedural documen-tation of the ODCM. Some of the tables were also replaced to improve legibility. These changes were made to improve readability and legibility. The changes do not affect the accuracy or reliability of the dose calculations or setpoint determinations. The procedure change was reviewed by PORC and approved on 3/8/89.
CHANGES TO THE PROCESS CONTROL PROGRAM (PCP)
The procedure documenting the Process Control Program was changed to include the Technical Specification reporting requirements to the procedure. This change does not affect any of the waste processing methods.
The procedure was review by PORC and approved on 6/28/89.
MAJOR CHANGES TO RADNASTE TREATMENT SYSTEMS There were no major changes to the Radwaste Treatment Systems during the reporting period.

- a. Activity from other isotopes caused an increased background resulting in the LLD calculation exceeding 5E-07 uCi/ml for the listed isotopes.
The higher than normal occurrences of exceeding LLD requirements were due to the following:
Due to the 10 Year ISI program, the reactor cavity was flooded for 21 days instead of the normal 7 days. This significantly increased the amount of liquid waste water which required processing.
2 ~ The increased quantity of waste water required the use of the recycle evaporator to process waste water. This evapora-tor system is not as efficient as the waste evaporator system which resulted in an increased concentration of contaminants in the releases.
