1.0 INTRODUCTION

This Annual Radioactive Effluent Release Report is for the Rochester Gas and Electric Corporation R.E. Ginna Nuclear Power Plant and is submitted in accordance with the requirements ofTechnical Specification Section 5.6.3. The report covers the period from January 1, 1998 through December 31, 1998.

This report includes a summary of the quantities of 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.

1 Allgaseous and liquid effluents discharged during this reporting period were in compliance with the limits ofthe R.E. Ginna Technical Specifications as defined in the Offsite Dose Calculation Manual (ODCM).

2.0 2.1 SUPPLEMENTAL INFORMATION Re ulato Limits The ODCM limits applicable to the 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 <<5 mrad for gamma radiation and to

<<10 mrad for beta radiation.

(ii)

During any calendar year to <<10 mrad for gamma radiation and to

<<20 mrad for beta radiation.

2.1.2 Radioiodine Tritium and Particulates The instantaneous dose rate, as calculated in the ODCM, 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 ifallowed to continue for a full year.

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.

2.1.3 Li uid Effluents The release of radioactive liquid effluents shall be such that the concentration in the circulating water discharge does not exceed the limitsspecified in accordance with Appendix B, Table II, Column 2 and notes thereto of 10CFR20.

For" dissolved or entrained noble gases the total activitydue to dissolved or entrained noble gases shall not exceed 2 E-4 pCi/ml.

The dose or dose commitment to an individual as calculated 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 any calendar year to < 3 mrerri to the total body and to < 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 ofdose rate at the unrestricted area boundary.

2.2.2 For liquid effluerits, ten times'the effluent concentration values specified in 10CFR20, Appendix B, Table II, column 2, are used to calculate release rates

. and permissible concentrations at the unrestricted area boundary as permitted by Technical Specification 5.5.4.b. Avalue of 2E-04 pCi/ml is used as the MPC for dissolved and entrained noble gases in liquid effluents.

2.3 Release Rate Limits The release rate limits forfission and activation gases from the R.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 1998 beta/gamma energy of the radionuclide mixture was 0.250 Mev.

2.4 Measurements and A roximations of Total Radioactivit Gamma spectroscopy was the primary analysis method used to determine the radionuclide composition and concentration of gaseous and liquid effluents.

Composite samples were analyzed for Sr-89, Sr-90 and Fe-55 by a contract lab-oratory. Tritium and alpha analysis were performed using liquid scintillation and gas flow proportional counting respectively.

The total radioactivity in effluent releases was determined from the measured concentration of each radionuclide present and the total volume of effluents released.

1. Number of batch releases:

1.82 E+02

2.6 Abnormal Releases There were no abnormal releases in 1998.

3.0

SUMMARY

OF GASEOUS RADIOACTIVEEFFLUENTS The quantities of radioactive material released in gaseous effluents are summarized in tables 1A and 1B. Plant vent and Containment Vent releases are modeled as mixed mode and Air Ejector is modeled as ground level release.

4.0

SUMMARY

OF LIQUIDRADIOACTIVEEFFLUENTS The quantities of radioactive material released in liquid effluents are summarized in tables 2A and 2B.

5.0 SOLID WASTE 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.

The majority of Dry Active Waste is processed utilizing an off-site processor who reduces the volume and then sends the waste for burial.

6.0 LOWER LIMITOF DETECTION There were no instances where the Lower Limitof Detection (LLD)was not met.

7.0 RADIOLOGICALIMPACT An assessment of doses to the maximally exposed individual from gaseous

and, liquid effluents was performed for locations representing the maximum dose.

In all cases, doses were well below Technical Specification limitsas defined in the ODCM.

Doses were assessed based upon actual meteorological conditions considering the noble gas exposure, inhalation, ground plane and ingestion pathways. The ingestion pathways considered were the fruit,vegetable, fish, drinking water, goat's milk, cow's milk and meat pathway. The results ofthis assessment are presented in Tables 4A and 4B.

8.0 METEOROLOGICALDATA The annual summary of hourly meteorological data collected during 1998 is not included with this report, but can be made available at the RGB E Ginna Plant.

9.0 LANDUSE CENSUS CHANGES There were no changes in critical receptor location for dose calculations during the reporting period.

There were no large changes in land use within 5 miles of the plant. Additional new homes were built.

10.0 CHANGES TO THE OFFSITE DOSE CALCULATIONMANUAL There were minor changes to the Offsite Dose Calculation Manual (ODCM) in 1998.

These included the following changes as reported in Ginna procedure change notification (PCN).

The PCN no. 98-6300 documented the following change; The restrictions on a Gas Decay tank were clarified when process radiation monitor R-14 was inoperable and what alternatives were available.

I The PCN no. 98-6310 documented the following change; A clarification was made regarding the component cooling system.

These changes were reviewed as part of a 10 CFR 50.59 analysis and found not to affect nuclear safety, and did not involve an unreviewed safety question.

11.0 CHANGES TO THE PROCESS CONTROL PROGRAM There were no changes to the Process Control Program during the reporting period.

5

12.0 MAJOR CHANGES TO RADWASTE TREATMENTSYSTEMS There were no major changes to the Radwaste Treatment Systems during the reporting period.

13.0 OPERATIONAL DISCREPANCIES Process Monitor R-14A was out of service in excess of7 days. The unit was placed out ofservice on 7/1 3/98 at 0530 forpreventative maintenance and calibrations. Due to other maintenance considerations, the repair ofthe process monitor exceeded the 7 day window. The unit was returned to service on 8/05/98.

During that time, other systems were available to accurately monitor the noble gas, particulate and iodine releases.
