INTRODUCTION This Semiannual Radioactive Effluent Release Report for the period of July 1 through December 31, 1991 is submitted in accordance with Section 6.9.1.8 of Appendix A to Grand Gulf Nuclear Station (GGNS) License No.

NPF-29.

That portion of Appendix A which refers to the monitoring of radioactive effluents, Sections 3/4-11 and 3/4-12, will hereafter be referred to as the Radiological Effluent Technical Specification (RETS).

Airborne discharges at GGNS are considered ground-level releases. All liquid and airborne discharges to the environment were analyzed in accordance with the RETS requirements. All effluent releases-were within the concentration and total release limits specified by the RETS.

Projected offsite doses were within the dose limits specified by the RETS.

The doses were projected using the methodology of the GGNS Offsite Dose Calculation Manual (ODCM).

The summation of all gaseous releases during the reporting period is given in Table 1A, while elevated releases and ground-level releases for the reporting period are given in Tables 1B and IC, respectively.

Table ID describes.the radioactive gaseous sampling and analysis program implemented at GGNS.

The summation of all' liquid releases during the reporting period is given-in Table 2A, while continuous and batch mode releases are given in Table 2B.

Table 2C describes the radioactive liquid waste sampling and analysis program-implemented at GGNS.

Solid radioactive waste and irradiated' fuel shipments during=

the reporting period are summarized in Table 3.

Meteorological data is included in Tables 4A - 40.

Table 4D presents atmospheric stability classifications.

Measurements and-Approximations of Total Activity.

The following discussion details the methods used to measure and approximate total activity for the following:

1.

Fission and Activation Gases 2.

Radiciodines 3.

Particulates 4

Liquid Effluents Tables 1D and 20 give sampling frequencies and minimum detectable sensitivity requirements for the analysis of gaseous and liquid effluent streams, respectively.

Values in the attached tables given as zero do not necessarily imply that the radionuclides were not present. A zero indicates that the radionuclide was not present at levels greater than the sensitivity requirements shown in Tables ID and 2C.

For some radionuclides, lower detection limits than required may be readily achievable; when a radionuclide is measured below its stated detection limits, it is reported.

1.

For Fission and Activation Gases The following noble gases are' considered in evaluating gaseous airborne discharges:

Ar-41 Xe-131m Kr-85m Xe-133 Kr-85 Xe-133m Kr-87 Xc-135m Kr-88 Xe-135 K r-89 Xe-138 Periodic grab samples from Station effluent streams are analyzed by a computerized pulse height analyzer system utilizing high-resolution germanium detectors.

(See Table 1D-for sampling and-analytlenl--

requirements.) Isotopic values thus obtained are used for dose release rate calculatiot.s due to_offluent releases as given in Section II.A.1. of this report.

Only those radionuclides that are detected are used in this computation.

During the period between grab samples, the amount of radioactivity released is based on the effluent monitor readings. Monitors are assigned a calibration. factor based

-upon the last isotopic analysis, using the following relationship:

C.

=

U1+m where C

=

isotopic calibration factor for isotope i p

SRER901.2/SRREVFLR - 5

concentration of isotope i in the grab sample in pCi/ml.

U

=

g not monitor reading associated with the effluent stream m =

(determined at the-time of grab sampling).

These calibration factors, along with the hourly effluent monitor values and flow rates, are entered into_the laboratory computer where y

the release rates for individual radionuclides are calculated and stored. If no auv 41*: is detected in the grab sample, the calibration factor def aults to a historical mixture of Kr-88, Xe-133, Xe-135m, Xe-135, and Xe-138, 2.

For Particulates and Radiolodines The radiciodines and radioactive materials in particulate form to be considered are:

Zn-65 I-133 Cr-51 Cs-134 Mn-54 Cs-136 Fe-59 Cs-137 30-58 Ba-140 Co-60 Ce-141 Sr-89 Ce-144 Sr-90 Other radionuclides Zr-95 with half-lives Sb-124 greater than I-131 8 days.

3.

For Continuous Releases Continuous sampling is performed on the continuous release points (i.e., Rt 3 waste Vent, Containment Purge, Fuel llandling Area Vent, Turbine Building Vent).

Particulate material is collected by filtration.

Radiciodines are collected by adsorption onto a: charcoal filter.

Periodically these filters-are removed and: analyzed on the pulse height analyzer to identify and quantify radioactive materials-collected on the filters.

Particulate filters are then analyzed for gross alpha and Strontium-89 and -90 as required. Gross alpha determinations are made using a 2-pi gas flow proportional counter..

Strontium-89 and -90 values are obtained by chemical separation and subsequent analysis using 2 pi gas flow proportional counters. During major operational occurrences, the frequency of sampling is increased to satiafy the requirements of footnote "c" of-Table 1D, "Radior cive Gaseous Waste Sampling and Analysie," (GGNS RETS, Table 4.11.7. 2-1).

4.

For Batch Releases: Gases The processing of batch type releases (from Containment Purge) is analogous to that for continuous releases, b

SRER401.2/SRREVFLR - 6

)

1 5.

For Batch Releases: Liquid Effluents The radionuclides listed below are considered when evaluating liquid effluents:

11 - 3 Mo-99 Co-58 Tc-99m Co-60 1-131 Fe-55 I-132 Fe-59 I-133 Zn-65 I-135 Mn-54 Cs-134 Cr-51 Cs 137 Sr-89 Ba-140 Sr-90 La-140 Nb-95 Cc-141 Zr-95 Co-144 Representative pre-release grab samplesLaro obtained and analyzed as required.by Table 20.

Isotopic analyses are performed using the computerized pulse height analysis system previously described.

Aliquots of each pre-released sample, proportionai ;o the waste volume released, are composited in accordance with the requirements of Table' 20.

Strontium determinations are made by performing a chemical separation an3 counting the separated strontium using a 2-pi gas flow l

proportional counter. Gross alpha determinations are made using 2-pi gas flow proportional counters.

Tritium and Iron-55 concentrations are determined by using liquid scintillation techniques. ' Dissolved gases are determined employing grab sampiing techniques and then counting on the pulse height analyzer system.

Sampling errors include uncertainty associated with mixing, representative sampling and discharge-volume. Measurement errors include uncertainty associated with instrument calibration and the preparation and counting of low-activity samples. Counting errors are based on measurements of blank samples and, for germanium detectors,-

-the Icast-readily-detectable radioisotope.

Calibration errors are calculated by summing the-errors associated with the calibration of a particular instrument _with a_ radioactive. source.

Total error is calculated by taking the square root of_the sum of the squares-of the individual errors.

III. 1991 RADIATION DOSE

SUMMARY

Indicated below is the annual summary of offsite doses attributable to GGNS during 1991.

Inspection of the values indicate that GGNS releases were within the 10CFR50,' Appendix I design objectives.

Since there are no other fuel cycle fac111 tics within 8 km.of GGNS, 40CFR190 limits have also been met during this period.

All parameters listed were calculated in accordance with the GGNS ODCM, A.

Water-Related Exposure Pathways The values calculated in this section utilize the_information provided in tables 2A and 2B of this report and the calculational methodology of the ODCM.

Liquid Effluents Total body dose and-critical organ doses are computed for the maximum exposed Individual.

The maximum dose contributaan from 11guld effluents is considered to occur in the adult age group via consumption of fish.

B.

Airborne-Related Exposure Pathways The values presented in this section utilize information provided in Tables 1A and IC of this report and the calculational methodology of the ODCM. Doses and dose rates are computed for locations at the alte boundary or at unrestricted areas within the site boundary. The use of

[

unrestricted areas within the site boundary as controlling receptor locations provides assurance that offsite doses will not be substantially underestimated, as well'as determining the radiation dose from gaseous ef fluents to members of the 'public due to their activities inside the site l

boundary.

Particulate, Radiofodine and Tritium--

Organ doses from exposure to radiciodines, tritium and-particulates are computed for an individual located in the south-sector at a distance of 0.5 miles.

This location correspands to one of the_ two onsite_ GGNS-gardens. Pathways considered in the dose calculations are inhalation, ground plane, grass / cow / milk, grass / cow / meat and vegetation. -For a particular radionuclide,-the maximum dose-factor obtainable from a combination of age groups and organs is used in the calculation of. organL dose.

Noble Gases Gamma and beta air ' dose and individual total body and skin dose rates from exposure to a semi-infinite cloud of noble gas are computed for a location in the west-northwest sector at a distance of 0.75 miles.- This

(

controlling location corresponds'to the highest. annual average atmospheric dispersion for an unrestricted area inside the site boundary-(ilamilton-Lake). The total body and skin doses reported below are derived from -the

-quarterly average-of the maximum instantaneous dose rates determined daily-during the reporting period.and would represent the maximum possible dose received by members of the public onsite.

SRER901.2/SRREVFLR - 11

7 Direct Radiation Direct radiation dose is calculated by subtracting average doses measured by thermoluminescent dosiroter (TLD) badges located at control locations from average doses measured by TLD badges-located near the' site boundary.
