Attachment I - Offsite Dose Calculation Manual, Revision 25 env-tec/ARRROI - 3

I. INTRODUCTION This Annual Radioactive Effluent Release Report (ARERR) for the period of January 1 through December 31, 2003 is submitted in accordance with Offsite Dose Calculation Manual (ODCM), Section 5.6.3 of Grand Gulf Nuclear Station (GGNS) License No. NPF-29.

The monitoring of radioactive effluents is referenced in ODCM Appendix A, Sections 6.1 1 and 6.12.

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

The summation of all gaseous releases during the reporting period is given in Table IA, while elevated releases and ground-level releases are given in Tables 1B and I C ,

respectively. Table 1D 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.

The annual summary of meteorological data (joint frequency distribution) will be maintained on site in a file that shall be provided to the Nuclear Regulatory Commission (NRC) upon request. The option to maintain meteorological data on site is in accordance with ODCM Administrative Controls Section 5.6.3.

C. Average Energy Not applicable for GGNS ODCM Appendix A, env-tedARERRO1 - 7

II. DETAILED INFORMATION (CONTD)

D. Measurements and Approximations of Total Activity The following discussion details the methods used to measure and approximate total activity for the following:

I Particulates Il Fission and Activation Gases Radioiodines I Liauid Effluents Ill Tables 1D and 2C 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 1D 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:

I Kr-87 1 Xe-I 33 I Xe-I35 I 1 Kr-88 I Xe-l33m I Xe-I38 1 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 analytical requirements.) Isotopic values thus obtained are used for dose release rate calculations due to effluent 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:

where Ci = isotopic calibration factor for isotope i Ui = concentration of isotope i in the grab sample in pCi/ml.

m = net monitor reading associated with the effluent stream (determined at the time of grab sampling).

env-lec/ARERROl -8

II. DETAILED INFORMATION (CONTD)

These calibration factors, along with the hourly effluent monitor values and flow rates, are entered into the laboratory computer where the release rates for individual radionuclides are calculated and stored. If no activity is detected in the grab sample, the calibration factor defaults to a historical mixture of Kr-88, Xe-I 33, Xe-I 35m, Xe-I 35, and Xe-I 38.

2. For Particulates and Radioiodines The radioiodines and radioactive materials in particulate form to be considered are:

Other radionuclides with half lives greater than 8 days.

3. For Continuous Releases Continuous sampling is performed on the continuous release points (i.e.,

OffgadRadwaste Building Vent, Containment Purge, Fuel Handling Area Vent, Turbine Building \lent). Particulate material is collected by filtration. Radioiodines 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 2-pi gas flow proportional counter.

Strontium-89 and -90 values are obtained by chemical separation and subsequent analysis using liquid scintillation techniques. Tritium concentrations are determined using distillation and liquid scintillation techniques. During major operational occurrences, the frequency of sampling is increased to satisfy the requirements of footnote c of Table 1D, Radioactive Gaseous Waste Sampling and Analysis, (GGNS ODCM Appendix A, Table 6.1 1.4-1). Currently, Strontium analysis is performed by a qualified contract laboratory.

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

env-tec/ARERROI -9

It. DETAILED INFORMATION (CONTD)

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

Representative pre-release grab samples are obtained and analyzed as required b: Tab1 2C. Isotopic analyses are performed using the computerized pulse height analysis system previously described. Aliquots of each pre-released sample, proportional to the waste volume released, are composited in accordance with the requirements of Table 2C.

Strontium-89, 90 and lron-55 values are obtained by chemical separation and counting the separated strontium and iron using liquid scintillation techniques. Gross alpha determinations are made using 2-pi gas flow proportional counter. Tritium is determined using distillation and liquid scintillation techniques. Dissolved gases are determined employing grab sampling techniques and then counting on the pulse height analyzer system. Currently, iron and Strontium analyses are performed by a qualified contract laboratory.

1. Liquid The maximum errors are collectively estimated to be as follows:

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 least-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.

env-tedARERRO1 - I 1

II. DETAILED INFORMATION (CONTDL

2. Gaseous The maximum errors (not including sample line loss) are collectively estimated to be as follows:

Sampling errors include uncertainty associated with sample flow, vent flow and monitor calibration.

Measurement errors include uncertainty associated with instrument calibration and preparation and counting of low-activity samples. Measurement and total errors are calculated by the same methods used for liquid effluents.

3. Solid Radioactive Waste See Table 3 for error terms.

H. Solid Radioactive Waste Shipments See Table 3 for shipment information.

I. Meteorological Data The data recovery for the reporting period was 91.2%. The predominant wind direction was from the Northeast approximately 11% of the time. The predominant stability class was class D approximately 36% of the time. Average wind speed during the reporting period was approximately 4.2 miles per hour.

The annual meteorological data (Hourly Average Data or Joint Frequency Distribution) will be maintained on site in a file that shall be provided to the NRC upon request.

J. Radioactive Effluent Monitoring Instrumentation Operability No reportable instances of inoperability occurred during the reporting period.

K. Annual Sewage Disposal Summary There were no sewage disposals in 2003.

111. RADIATION DOSE

SUMMARY

Indicated below is the annual summary of offsite doses attributable to GGNS during 2003. Inspection of the values indicate that GGNS releases were within the IOCFRSO, Appendix I design objectives.

Since there are no other fuel cycle facilities 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 contribution from liquid effluents is considered to occur in the adult age group via consumption of fish.

2003 Liauid Effluent Dose fmrem)

B. Airborne-Related Exposure Pathways The values presented in this section utilize information provided in Tables 1A and 1C of this report and the calculational methodology of the ODCM. Dose and dose rates are computed for locations at the site boundary or at unrestricted areas beyond the site boundary. Because members of the public may, on occasion, be found within the site boundary, locations within the site boundary were considered when selecting locations for dose calculations.

Consideration of site boundary locations as well as unrestricted areas within and beyond the site boundary provides assurance that offsite doses will not be substantially underestimated while attempting to provide an accurate dose calculation.

The most limiting location for a member of the public is used for the dose calculations.

During routine operations the dispersion and deposition factors used for dose calculations are from historical annual average meteorological data.

111. RADIATION DOSE

SUMMARY

JCONTD)

Organ Dose The maximum organ dose to a MEMBER OF THE PUBLIC (critical receptor) from radioiodines, tritium and particulates was calculated for this report using the most recent land use census and dispersion and deposition parameters from 2003 meteorological data. The critical receptor residence was determined to be located in the southwest sector at a distance of 1432 meters (0.89 miles) from the plant. Pathways considered for use in the organ dose calculations are inhalation, ground plane, grass/cow/meat and vegetation. There is no grass/cow/milk pathway within five miles of GGNS. It was assumed that the age group receiving the maximum dose lived at the residence and that the receptor consumed food products that were raised or produced at the residence.

Average Total Bodv and Skin Dose Rate Individual total body and skin dose rates from exposure to a semi-infinite cloud of noble gas are computed for a location in the southwest sector at a distance of 0.85 miles. This location corresponds to the highest annual average atmospheric dispersion factor for a location at the site boundary.

The total body and skin dose rates reported are the quarterly average of the maximum instantaneous dose rates determined daily during the reporting period and would represent the maximum possible dose rate received by members of the public.

Air Dose From Gamma and Beta Emissions Air doses from gaseous effluents were calculated for this report using dispersion parameters from the 2003 meteorological data. The highest dispersion factor for an unrestricted area was in the southwest sector at the site boundary, 1368 meters (0.85 miles) from the plant.

Direct Radiation Direct radiation dose is calculated by subtracting average doses measured by thermoluminescent dosimeter (TLD) badges located at control locations from average doses measured by TLD badges located near the site boundary. GGNS reported measured doses in 2003 as net exposure normalized to 92 days.

IV. OFFFSITE DOSE CALCULATION MANUAL/

RADIOACTIVE WASTE TREATMENT SYSTEM CHANGES A. Offsite Dose Calculation Manual (ODCM)

One revision to the ODCM was processed during the reporting period. The changes are summarized below.

Revision 25:

o Updates the historical annual average dispersion and deposition parameters.

o Updates the Land Use Census data.

o Clarification of dispersion calculation methodology o Additional guidance for calculating dose within SITE BOUNDARY.

o Editorial changes to improve the timeliness of future dispersion parameter changes.

o Routine Editorial changes B. Radioactive Waste Treatment Systems A Reverse Osmosis (RO) unit was incorporated into the Liquid Radioactive Waste Treatment System in 2003. The RO unit was installed to reduce the volume of solid radioactive waste generated. The information required by the Offsite Dose Calculation Manual 5.6.3b specification will be provided in the next UFSAR update.

INTRODUCTION The Offsite Dose Calculation Manual (ODCM) describes the methodology and parameters used in the calculation of offsite doses resulting from radioactive liquid and gaseous effluents, in the calculation of liquid and gaseous effluent monitoring Alarm/Trip Setpoints, and in the conduct of the Radiological Environmental Monitoring Program. The ODCM also contains ( 1 ) the Radioactive Effluent Controls and Radiological Environmental Monitoring Programs required by Technical Specification (TS) 5.5.4, and Technical Requirement 7.6.3.2, ( 2 )

descriptions of the information that is included in the Annual Radiological Environmental Operating and Annual Radioactive Effluent Release Reports required by TS 5.6.2 and 5.6.3, (3) a list and graphical description of the specific sample locations for the Radiological Environmental Monitoring Program, and (4) diagrams of the liquid and gaseous radwaste treatment systems.

ODCM Revision 25 incorporates the following change: I Updates land use census data and updates dispersion and deposition constants using 1996-2000 meteorological data.

References added for atmospheric dispersion calculations.

Dose calculation variable definitions modified to reference tables for appropriate dispersion factors.

Added a more detailed explanation on dose calculation methodology for "Unrestricted Area Dose to IndividualN.

Added option to use dispersion factors from appropriate calculations when evaluating dose to members of the public that are located inside the site boundary.

Added more detail and software input parameters to calculate Atmospheric Dispersion for long term releases using XOQDOQ software.

Deleted Figure 2.3-4, "Open Terrain Recirculation Factor", graph.

Site specific data will be used for the recirculation factor if short term atmospheric dispersion constants are calculated.

Modified formula for short term atmospheric dispersion and deposition calculations based on study performed by R. S. Reynolds for GGNS Meteorological monitoring.

Changed temperature differential units and table from "K/100m to "F/40m.

Editorial changes, changed "cc" to "sec" for units in Tables 2.2-2a-d and changed "EFFUENT" TO "EFFLUENT" in Section 6.11.2.

Removed the word "CONTROL" from TLD M-33 in Table 3.0-3.

GRAND GULF, UNIT 1 ii Revision 25 - 01/03

The ODCM will be maintained at the station for use as a reference guide and training document of accepted methodologies and calculations. Changes in the I

calculational methods or parameters will be incorporated into the ODCM in order to assure that the ODCM represents the present methodology in all applicable areas. Computer software to perform the described calculations will be maintained current with the ODCM.

Changes to the ODCM shall be accomplished as specified in TS 5.5.1.

Records of reviews performed for changes made to the ODCM shall be retained for the duration of the Unit Operating License.

C = ten times the effluent concentration limit (LCO 6.11.1) implementing 10CFR20 for the site, in pCi/ml.

c = The setpoint, representative of a radioactivity concentration in pCi/ml, of the radioactivity monitor measuring the radioactivity in the waste tank effluent line prior to dilution and subsequent release; the setpoint, which is inversely proportional to the volumetric flow of the effluent line and directly proportional to the volumetric flow of the dilution stream plus the waste tank effluent stream, represents a value which, if exceeded, would result in concentrations exceeding ten times the limits of 10CFR20 in the unrestricted area.

GRAND GULF, UNIT 1 1.0-1 Revision 17 - 03/95

f = the waste tank effluent flow setpoint as measured at the radiation monitor location, in volume per unit time, but in the same units as F, below.

F = the dilution water flow setpoint as measured prior to the release point, in volume per anit time.

At Grand Gulf Unit 1, the available dilution water flow ( F )

should be constant for a given release, and the waste tank flow (f) and monitor setpoint (c) are set to meet the condition of equation 1 or a given effluent concentration, C. The method by which this is accomplished is as follows:

Step 1) The isotopic concentration for a waste tank to be released is obtained from the sum of the measured concentrations as determined by the analysis required in ODCM Table 6.11.1-1:

cc. = cc + ca iccs t CL + Cf (2) 1 g i i g S where :

X C = the sum of concentrations C of each measured Gamma g g FI emitter observed by gamma-ray spectroscopy of the waste sample ..

Ca = the concentration C of gross alpha emitters in a

liquid waste a5 measured in the monthly composite sample.

CsCs = the measured concentrations of Sr-89 and Sr-90 in liquid waste as observed in the quarterly composite sample.

GRAND GULF, UNIT 1 1.0-2 Revision 17 - 03/95

I Ct = the measured concentration of H - 3 in liquid waste as determined from analysis of the monthly composite sample.

Cf = the concentration of Fe-55 in liquid waste as measured in the quarterly composite sample.

The C term will be included in the analysis of each waste 9

tank batch to be released; terms for alpha, strontiums, tritium and iron are included if analysis of liquid waste has shown the presence of these isotopes.

Step 2) The measured radionuclide concentrations are used to calculate a Dilution Factor, D . F . , which is the ratio of total dilution flow rate to waste tank effluent flow rate required to assure that ten times the limiting concentration of 10CFR20, Appendix B, Table 2, Column 2 are met at the point of discharge.

i C C g a s Ct cf where:

ci = c g , Ca, Cs, Ct and Cf; measured concentrations as defined in Step 1. Terms C Cs, C and C will be a t f included in the calculation as appropriate.

GRAND GULF, UNIT 1 1.0-3 Revision 17 - 03/95

ECi = EC EC,, EC ,EC and EC are ten times the 4, s t f limiting concentrations of the appropriate radionuclide from 1CCFR20, Appendix B, Table 2, Column 2. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-4 pCi/ml total activity.

S.F. = an administrative safety factor normally applied at Grand Gulf which causes the calculated Dilution Factor to be two (2) times larger than the dilution factor required for compliance with ten times 10CFR20 limits.

Step 3) The maximum permissible waste tank effluent flow rate prior to dilution, is calculated based on a fixed fraction of the dilution flow rate, Fd :

Fd ' fd Fd f < z7 for F >>f d - d d D.F. c . F.

where:

= 0.9 x minimum expected dilution flow rate Fd

= maximum permissible waste tank effluent flow rate fd D.F. = Dilution Factor from Step 2.

NOTE : Equation 4 is valid only for D.F.>l; for D.F.51, the waste tank effluent concentration meets the limits of ten times the limiting concentrations of 10CFR20 without dilution, and f may take on any desired value.

d Step 4) The dilution flow rate setpoint for minimum dilution flow rate, F, and waste tank flow rate setpoint for maximum waste tank effluent flow rate, f, are calculated as follows:

F = F = 0.9 x minimum expected dilution flow rate(5) d f = 0.9 x f = 0.9 x calculated maximum waste tank flow d

rate for the stated release conditions.(6)

GriAND GULF, UNIT 1 1.0-4 Revision 15 - 01/94

I Thus, if instrumentation indicates the dilution flow rate falls below the assumed flow rate of 90 percent of the actual dilution flow, or if the waste tank effluent flow rate exceeds 90 percent of the calculated maximum waste tank effluent flow rate, the release is terminated (manually or automatically).

Step 5) The radioactivity monitor setpoint may now be specified based on the values of E.C. F, and f which were specified I 1, to provide compliance with ten times the limits of 10CFR20, Appendix B, Table 2, Column 2. The monitor response is primarily to gamma radiation; therefore, the actual setpoint is based on 2 C . The setpoint concentration, Cm, is 9 9 determined as follows:

fd cm -- ~

CC (pCi/ml) 9 (7) fa g where f is the actual (or maximum expected) waste tank a

effluent flow rate, The value of C (pCi/ml) is used to m

determine the monitor setpoint (CPM) from a calibration curve similar to ODCM Figure 1.0-1.

NOTE : Setpoint adjustments are not required if the existing setpoint corresponds to a lower count rate than the calculated value. The actual monitor setpoint is determined from the measured concentration plus background for the detector. The setpoint contains a factor of conservatism, even if the calculated maximum waste tank flow rate is attainable, since the calculated rate contains the safety factor margin, waste tank effluent flow rate margin, and the dilution flow rate margin. In practice, the actual waste tank effluent flow rate normally is many times less than the calculated tank flow rate, thus providing an additional conservatism during release.

GRAND GULF, UNIT 1 1.0-5 Revision 17 - 03/95

NOTE : For cases where no gamma emitters are detected, i.e.

CC = 0, the monitor setpoint should be set at 2700 cpm 4

plus background. The 2700 cpm is based on Cesium-137 monitor response and the limits specified in LCO 6.11.1. (Iz)

NOTES For Section 2.1.1

1) The calculated setpoint values will determine the allowable bounds for the actual setpoint adjustments. That is, setpoint adjustments are not required to be performed if the existing setpoint level corresponds to a count rate that is less than or equal to + 25% of the calculated value.

If radionuclides are not detected in the grab sample, then the previously calculated setpoint may remain as the valid setpoint.

2) A conservative setpoint may be calculated using a composite total body dose factor. This method may be used when there are no valid isotopics available. The conservative setpoint will be calculated as follows:

= count rate (cpm) above background of vent noble gas monitor at the sv alarm setpoint level*

= PF' x DTB x Rt" where :

I PF = product of allocation factor (AF) and safety factor (SF'), normally set at 0.1 I AF = allocation factor allowing for a total of four normal effluent release points, normally set at 0.25 SF' = safety factor allowing for cumulative uncertainties of measurements, normally set at 0.4.

Rt" = conservative count rate per mrem/yr to the total body (Xe-133 detection, composite dose factor)

= (3.53E-5) ( 6 0 )

The setpoint calculation based on a skin dose is not required because the setpoint based on the total body dose is more conservative.

I 2.6 Annual Dose Commitment If required, the annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC will be calculated by summing the following doses for the calendar year:

. Direct radiation dose Liquid effluent dose (DTau)

Noble gas dose (D Y

Particulate dose (D )

P These calculations are required only if the liquid or gaseous effluents exceed twice the limits of LCOs 6.11.2, 6.11.5 and 6.11.6.

2.6.1 Direct Radiation Dose Measurement LCOs 6.11.2, 6.11.5 and 6.11.6 require the determination of cumulative dose contributions to a MEMBER OF THE PUBLIC from direct radiation from the reactor units and from radwaste storage tanks. This requirement is applicable only under conditions set forth in Action 8.1 of the applicable LCO. This determination is made by the utilization of direct radiation measurements from indicator thermoluminescent dosimeters (TLDs) located near the GGNS property line in eight of the 16 meteorological sectors.

GRAND GULF, UNIT 1 2.0-36 Revision 20 - 07/96

Measurements from these TLDs represent the direct radiation generated by the facility plus normal background radiation. The locations are identified in ODCM Table 3.0-3 by the foilowing TLD numbers:

M-16 M-22 M-23 M-19 M-25 M-17 M-21 M-28 Control TLDs are also utilized to differentiate between background radiation and direct radiation from the facility. The following two TLDs are designated as controls based on the criterion that they are located ten miles or greater from the facility. Exact locations are identified in ODCM Table 3.0-3.

M-14 M-33 The difference between the averaged quarterly radiation measurements of the indicator TLDs and the control TLDs represents the direct radiation dose to a MEMBER OF THE PUBLIC from the operating facility.

(Current literature defines the LLD as the detection capability for the instrumentation only, and the MDC, minimum detectable concentration, as the detection capability for a given instrument, procedure, and type of sample.)

Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute)

E is the counting efficiency (as counts per disintegration)

V is the sample size (in units of mass or volume) 2.22 x lo6 is the number of disintegrations per minute per microcurie Y is the fractional radiochemical yield (when applicable) h is the radioactive decay constant for the particular radionuclide At is the elapsed time between sample collection (or end of the sample collection period) and time of counting The value of Sb used in the calculation of the LLD for a particular measurement system should be based on the actual observed variance of the background counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicated variance.

Typical values of E, V, Y and At should be used in the calculation.

It should be recognized that the LLD is defined as an 2 priori (before the fact) limit representing the capability of a measurement system and not as g posteriori (after the fact) limit for a pasticular measurement.

Typical values of E, V, Y and At should be used in the calculation.

It should be recognized that the LLD is defined as an g priori (before the fact) limit representing the capability of a measurement system and not as a posteriori (after the fact) limit for a particular measurement.

6.11 RADIOACTIVE EFFLUENTS BASES LIQUID EFFLUENTS 6.11.1 CONCENTRATION This LCO is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than ten times the effluent concentration values specified in Appendix B, Table 2, Column 2 to 10 CFR 20.1001-20.2402. It provides operational flexibility for releasing liquid effluents in concentrations to follow the Section 1I.A and 1I.C design objectives of Appendix I to 10 CFR Part 50. This limitation provides reasonable assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within (1) the Section 1I.A design objectives of Appendix I, 10 CFR 50, to a MEMBER OF THE PUBLIC, and (2) restrictions authorized by 10 CFR 20.1301(e). The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radionuclide and its effluent concentration in air (submersion) was converted to an equivalent concentration in water. This LCO does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301 (a).

The results of pre-release analyses and post release analyses (of composited samples) shall be used with the calculational methods and parameters in the ODCM to assure that the concentrations at the point of release are maintained within the limits.

6.11.2 DOSE This LCO is provided to implement the requirements of Sections II.A, II1.A and 1V.A of Appendix I, 10 CFR Part 50. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section 1V.A of Appendix I which assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." Also, for fresh water sites with drinking water supplies which can be potentially affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR 141. The dose calculations in the ODCM implement the requirements in Section 1II.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.

RADIOACTIVE EFFLUENTS 6.11.2 DOSE (Continued)

The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 1 0 CFR Part 50, Appendix 1," Revision 1, October 1977 and Regulatory Guide 1.113, '+EstimatingAquatic Dispersion of Effluent from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix 1," April 1977.

This LCO, in conjunction with LCOs 6.11.5 and 6.11.6 is also provided to meet the dose limitation of 4 0 CFR 190 that has been incorporated into 10 CFR 20.1301(d).

Even if a site contained up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR 190 if the individual reactors remain within twice the dose design objectives of 10 CFR 50 Appendix I, and the direct radiation doses from the units (including outside storage tanks, etc.) are kept small.

Special Report:

LCO 6.11.2 requires preparation and submittal of a report in accordance with 10 CFR 50.4 and as defined in 10 CFR 20.2203(a)(4), if the dose design objectives of 10 CFR 50 Appendix I are exceeded.

If either the quarterly or the annual limit is exceeded, the report will:

(1) identify the cause(s) for exceeding the limit(s) ,

(2) define the corrective actions that have been taken to reduce the releases, and (3) define the corrective actions to be taken to ensure that future releases will be in compliance with the limits.

If, a drinking water supply is taken from the receiving water body within three miles downstream of the plant discharge, the report shall also include:

(1 results of radiological analyses of the drinking water source, and (2 the radiological impact on finished drinking water supplies with regard to the requirements of 40 CFR 141.

If the doses exceed the limits of 4 0 CFR 190, 25 mrems to the whole body or any organ, except the thyroid, which is limited to 75 mrems, the report shall:

(1 define the corrective action to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits, (2) include the schedule for achieving conformance with the above limits, (3) include an analysis that estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report, (4) describe the levels of radiation and concentrations of radioactive material involved, (5) describe the cause of the exposure level or concentrations involved, GRAND GULF, UNIT 1 A-64 Revision 17 - 03/95

RADIOACTIVE EFFLUENTS 6.11.2 DOSE (Continued)

(6) describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR 190 limits.

For the purposes of the report it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible, with the exception that the dose distribution from other nuclear fuel cycle facilities at the same site or within a radius of 8 kilometers must be considered.

The Special Report with a request for a variance (provided the release conditions resulting in a violation of 40 CFR 190 have not already been corrected), in accordance with the provisions of 40 CFR 190.11 and 10 CFR 20.2203(a) ( 4 1 , is considered to be a timely request and fulfills the requirements of 40 CFR 1 9 0 until NRC staff action is completed. The variance only relates to the limits of 40 CFR 190, and does not apply in any way to other requirements for dose limitations of 10 CFR 20, as addressed in LCOs 6.11.1 and 6.11.4. An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

Demonstration of compliance with the limits of 40 CFR 190 or with the design objectives of Appendix I to 1 0 CFR 5 0 will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR 20.1301.

The specified limit governing the use of appropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the dose design objectives set forth in Section I1.A of Appendix I, 10 CFR Part 50, for liquid effluents.

Special Report:

LCO 6.11.3 requires preparation and submittal of a report in accordance with 10 CFR 50.4 if radioactive liquid waste is being discharged without treatment and in excess of the limits. The report shall include:

(1) an explanation why liquid radwaste was being discharged without treatment, (2) identification of any inoperable equipment or subsystems which resulted in liquid radwaste being discharged without treatment, (3) the reason for the inoperability (4) actionls) taken to restore the inoperable equipment to an OPERABLE status, (5) summary descriptions of actions taken to prevent a recurrence.

GASEOIJS EFFLUENTS 6.11.4 DOSE RATE This LCO provides reasonable assurance that radioactive material discharged in ga.seous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, either at or beyond the SITE BOUNDARY in excess of the design objectives of Appendix I to 10 CFR Part 50. This specification is provided to ensure that gaseous effluents from all units on the site will be appropriately controlled.

It provides operational flexibility for releasing gaseous effluents to satisfy the Section 1I.A and 1I.C design objectives of Appendix I to 10 CFR Part 50. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of that MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for the reduced atmosphere dispersion of gaseous effluents relative to that for the SITE BOUNDARY.

The calculational methods and parameters in the ODCM are used to assure that the dose rates are maintained within the limits. Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, shall be given in the ODCM. The specified release rate limits restrict, at all times, the corresponding dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrem/year to the total body or to less than or equal to 3000 mrem/year to the skin. These releases rate limits also restrict, at all times, the corresponding.thyroiddose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrem/year. This specification does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301(a).

The dose rate due to radioactive gaseous effluents shall be determined in accordance with the methodology and parameters of the ODCM.

6.12 RADIOLOGICAL ENVIRONMENTAL MONITORING BASES 6.12.1 MONITORING PROGRAM The radiological monitoring program required by this LCO provides measurements o f radiation and of radioactive materials in those exposure pathways and for those radionuclides, which lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 5 0 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. The initially specified monitoring program will be effective for at least the first three years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The detection capabilities required by Table 6.12.1-3 are state-of-the-art for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an "a priori" (before the fact) limit representing the capability of a particular measurement. Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions.

Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.

For a more complete discussion of the LLD, and other detection limits, see the following:

(1) HASL Procedure Manual, HASL-300 (revised annually).

(2) Currie, L. A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal-Chem. 40, 586-93 (1968).

(3) Hartwell, J. K., "Detection Limits for Radioisotopic Counting Techniques,"

Atlantic Richfield Hanford Company Report ARH-2537 (June 22, 1972).

If milk or broadleaf vegetation sampling locations are relocated, the cause shall be reported in the next Annual Radioactive Effluent Release Report. Also, include in this report, revised ODCM figure(s) and table(s) reflecting the new locations. The specific locations from which samples were unavailable may then be deleted from the radiological environmental monitoring program and the table(s) in the ODCM, provided the locations from which the replacement samples were obtained are added to the table(s) as replacement locations.

The requirement for participation in an approved Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measures of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are valid for the purposes of Section IV.B.2 of Appendix I to 10 CFR Part 50.

6.12 RADIOLOGICAL ENVIRONMENTAL MONITORING 6.12.1 MONITORING PROGRAM (Continued)

Special Report:

LCO 6.12.1 requires preparation and submittal of a report in accordance with 10 CFR 50.4 when:

(1) the level of radioactivity as a result of plant effluents in an environmental sampling medium at a specified location exceeds the reporting level(s) in ODCM Table 6.12.1-2 when averaged over a calendar quarter, or (2) more than one of the radio nuclides in ODCM Table 6.12.1-2 are detected in the sampling medium and concentration (11 + concentration (2) + ...21.0, or reporting level (1) reporting level (2)

(3) radio nuclides other than those in ODCM Table 6.12.1-2 are detected, and the potential annual dose to a MEMBER OF THE PUBLIC is equal to or greater than the calendar year limits of LCOs 6.11.2, 6.11.5 and 6.11.6.

The report shall:

(1) identify the cause(s) for exceeding the limit ( s ) , and (2) define the corrective actions to be taken to reduce radioactive effluents so the potential annual dose to a MEMBER OF THE PUBLIC is less than the calendar year limits of LCOs 6.11.2, 6.11.5 and 6.11.6.

The Special Report is not required if the measured level of radioactivity is not the result of plant effluents; however in such an event, the condition shall be reported and identified in the Annual Radiological Environmental Operating Report.

6.'12.2 LAND USE CENSUS This LCO is provided to ensure that changes in the use of areas at and beyond the SITE B O W A R Y are identified and that modifications to the radiological environmental monitoring program are made if required by the results of the census. The best information from door-to-door survey, visual or aerial survey or from consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 50 m2 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and (2) a vegetation yield of 2 kg/m2. Specifications for broad leaf vegetation sampling in the Table 6.12.1-1 shall be followed, including analysis of control samples.

The results of the land use census shall be included in the Annual Radiological Environmental Operating Report pursuant to Technical Specification 5 . 6 . 2 .

When the Land Use Census requires addition of sampling location(s) to the Environmental Monitoring Program, the sampling locations(s) having the lowest calculated dose or dose commitments(s), via the same exposure pathway, may be deleted from the monitoring program. This deletion may take place after October 31 of the year in which this land use census was conducted.

The new sampling location(s) shall be identified in the next Annual Radioactive Effluent Release Report including a revised figure(s) and table(s) for the ODCM.
