1 ~ 0 INTRODUCTION This Semiannual Radioactive Effluent Release Report is for Rochester Gas and Electric Corporation 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,

1991 through June 30, 1991.

This'eport 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.

Corrected forms for liquid effluents released during the July December 1990 period are included as Tables 5A and 5B to show data which was not available when the report was prepared.

Table 3 listing isotopic data for radwaste shipments was incomplete during the July-December 1990 report and a corrected table is included as Table 6 with this report.

The table as printed only accounted for 2/3 of the total activity shipped.

All gaseous and liquid effluents discharged during this reporting period were in compliance with the limits of the R.E.

Ginna Technical Specifications.

During this report period, 5 of the liquid effluent monitors were replaced with new monitors.

The Tech.

Spec.

allows releases to be made when specific sampling programs are followed. when monitors are inoperable.

Several monitors were inoperable for more than 30 days, and either the sampling requirements were met or the releases were,not made for all situations.

2.1 SUPPLEMENTAL INFORMATION Re ulato 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.

T'h t

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.

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 if allowed to continue for a full year.

J 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.

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 noble gases shall not exceed 2 E-4 uCi/ml.

The dose or dose commitment to an individual as calcu-

'ated 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 mrem to the total body and to < 10 mrem to any organ.

Maximum Permissible Concentrations MPC 2 ~ 2 ~ 1 2 '

For gaseous effluents, maximum permissible concentrations are not directly used in'elease rate calculations since the applicable limits are sta'ted in terms of dose rate at the unrestricted area boundary.

For liquid effluents, the'aximum 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.

2 '

Release Rate Limits 2 '

The release rate limits for fission 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 energy of the,radionuclide mixture was 0.217 Mev.

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 was deter-mined from the measured concentration of each radio-nuclide present 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.

All releases were considered to be elevated releases.

SUMMARY

OF LIQUID RADIOACTIVE EFFLUENTS The quantities of radioactive material released in licpxid effluents are summarized in tables 2A and 2B.

SOLID WASTES The quantities of radioactive material released in shipments of solid waste 'ransported 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 LIMIT OF DETECTION NOT MET One or more gamma emitting radionuclides did not meet the required lower limit of detection for 14 liquid releases.

These are listed by release number in Table 4 ~
