Revision 33 Page 12 of 120 4.0 RADIOACTIVE LIQUID EFFLUENTS 4.1 CONCENTRATION (10 CFR 20)

4.1.1 CONTROLS

1. The release of radioactive liquid effluents shall be such that the concentration in the circulating water discharge does not exceed ten times the concentration values specified in Appendix 8, Table 2, Column 2 to 10 CFR Part 20.1001 -

20.2402. For dissolved or entrained noble gases, the total activity due to dissolved or entrained noble gases shall not exceed 2.0E-04 µCi/ml.

4.1.2. APPLICABILITY

At all times.

4.1.3 ACTION

If the concentration of radioactive material in *the circulating water discharge exceeds ten times the concentration values of Appendix B, Table 2, Column 2 of 10 CFR 20, measures shall be initiated to restore the concentration to within these limits immediately.

4.1.4 ACTION

If the concentration when averaged over one hour exceeds ten times the applicable concentrations specified in Appendix B of 10CFR Part 20, Table 2, Column 2, at the point of entry to receiving waters, submit to the commission a special report within 30 days.

4.1.5 SURVEILLANCE REQUIREMENTS:

1. Radioactive liquid wastes shall be sampled and analyzed according to the sampling and analysis program of Table 4-1. The results of pre-release analyses shall be used with the calculational methods in Section 4.6 to assure that the concentration at the point of release is limited to the values in Section 4.1.1 (Radioactive Liquid Effluents - Controls).

4.1.6 BASES

This control is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than the concentration levels specified in 10 CFR 20, Appendix B, Table 2, Column 2. This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within (1) the Section II.A design objectives of Appendix I, 10 CFR 50, to a MEMBER OF THE PUBLIC, and (2) the limits of Appendix 8, 10 CFR 20, to the population. The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its MPC in air (submersion) was converted to an equivalent concentration in water using the

CY-Gl-170-300 Revision 33 Page 13 of 120 methods described in International Commission on Radiological Protection (ICRP)

Publication 2.

CY-Gl-170*300 Revision 33 Page 14 of 120 4.2 DOSE (10 CFR 50 APPENDIX I)

4.2.1 CONTROLS

1. The dose or dose commitment to a MEMBER OF THE PUBLIC from radioactive materials in liquid effluents released to UNRESTRICTED AREAS shall be limited:

A. during any calendar quarter to s 1.5 mrem to the total body and to s 5 mrem to any organ, and B. during any calendar year to s 3 mrem to the total body and to s 10 mrem to any organ.

4.2.2 APPLICABILITY

At all times.

4.2.3 ACTION

Whenever the calculated dose resulting from the release of radioactive materials in liquid effluents exceeds any of the above limits, a Special Report shall be submitted to the Commission within thirty days which includes the following information:

1. identification of the cause for exceeding the dose limit;

2. corrective actions taken and/or to be taken to reduce the releases of radioactive material in liquid effluents to assure that subsequent releases will remain within the above limits;

3. The results of the radiological analyses of the nearest public drinking water source, and an evaluation of the radiological impact due to licensee releases on finished drinking water with regard to the requirements of 40 CFR 141, Safe Drinking Water Act.

4.2.4 ACTION

During any month when the calculated dose to a MEMBER OF THE PUBLIC exceeds 1/48 the annual limit (0.06 mrem to the total body or 0.2 mrem to any organ), projected cumulative dose contributions from liquid effluents shall be determined for that month and at least once every 31 days for the next 3 months.

4.2.5 SURVEILLANCE REQUIREMENTS:

Post-release analyses of samples composited from batch releases shall be performed in accordance with Table 4-1. The results of the post-release analyses shall be used with the calculational methods in Section 1.6 to assure that the dose commitments from liquids are limited to the values in Section 4.2.1 (Dose -

Controls).

CY-Gl-170-300 Revision 33 Page 15 of 120

4.2.6 BASES

This control is provided to implement the requirements of Sections II.A, Ill.A, and IV.A of Appendix I, 10 CFR 50. This control implements the guides set forth in Section II.A of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as reasonably achievable". Also, with Lake Ontario drinking water supplies potentially affected by plant operations, tliere is reasonable assurance that the operation of the plant will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR 141. The dose calculation methodology and parameters in the ODCM implement the requirements in Section Ill.A of Appendix I that conformance with the guides of Appendix I be shown by calculational models and data, such that the actual exposure of a MEMBER OF THE PUBLIC appropriate pathways is unlikely to be substantially underestimated. 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, 11 Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR 50, Appendix 111 ,

Revision 1, October 1977, and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I", April 1977.

CY-Gl-170-300 Revision 33 Page 16 of 120 4.3 TQTAL DOSE (40 CFR PART 190)

4.3.1 CONTROLS

The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.

4.3.2 APPLICABILITY

At all times.

4.3.3 ACTION

With the calculated doses from the release of radioactive materials in liquid effluents exceeding twice the limits of Section 4.2.1 (Dose - Controls), prepare and submit to the Commission within 30 d~ys a Special Report that defines the corrective actions to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and include scheduling for achieving conformance with the above limits. Calculations which include direct radiation contributions from the unit and from any radwaste storage shall be performed to determine total dose to a member of the public. This Special Report, as defined in 10 CFR 20.405(0}

shall 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 releases covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations. If the estimated dose(s) exceeds the above limits, and if the release condition resulting in violation of 40 CFR 190 has not already been corrected, the Special Report shall fnclude a request for a variance in accordance with the provisions of 40 CFR 190. Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.

4.3.4 SURVEILLANCE REQUIREMENTS:

1. - Cumulative dose contributions from liquid and gaseous effluents for the current calendar quarter and the current calendar year shall be determined in accordance with SURVEILLANCE REQUIREMENT S.1.2.1 at least once every 31 days, in accordance with the methodology and parameters of Section 1.7 of the ODCM.

2. Cumulative dose contributions from direct radiation from the unit and from radwaste storage shall be determined from environmental dosimeter data at least quarterly.

4.3.5 BASES

This control is provided to meet the dose limitations of 40 CFR 190 that have been incorporated into 10 CFR 20 by 46FR 18525. The specification requires the

CY-Gl-170-300 Revision 33 Page 17 of 120 preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrems to the whole body or any organ 1 except the thyroid, which shall be limited to less than or equal to 75 mrems. 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 plant remains within twice the dose design objectives of Appendix 11 and if direct radiation doses are kept small. The Special Report will 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 Special Report 1 it may be assumed that the dose contributions from other uranium fuel cycle sources is negligible. If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40 CFR 190, the Special Report with a request for a variance, (provided the release conditions resulting in violation of 40 CFR 190 have not already been corrected), in accordance with the provisions of 40 CFR 190.11 and 10 CFR 20.405c, is considered to be a timely request and fulfills the requirements of 40 CFR 190 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 the other- requirements for dose limitation of 10 CFR 20, as addressed in Section 4.1 .1 (Radioactive Liquid Effluents - Controls) and Section 5.2.1 (Dose Rate - Controls). 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.

CY-Gl-170-300 Revision 33 Page 19 of 120 Table4-1 Table Notation (a) The LLD is the smallest concentration of radioactive material in a sample that will yield a net count above system background that will be detecteq with 95%

probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal. The LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement, the minimum detectable activity (MDA).

For a particular measurement system (which may include radiochemical separation):

_ (4.66) (.S'~)

LLD - (Y)(E)(V) (2.22 E + 06)[exp (-Ai) J Where:

LLD = the lower limit of detection as defined above as µCi per unit mass or volume Sb = the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate as counts per disintegration V = the sample size in units of mass or volume E* = the counting efficiency Y = the fractional radiochemical yield when applicable 2.22E+06 is the number of disintegrations per minute per µCi

'J.. = the decay constant t = the time elapsed since sample time The value of Sb used in the calculation of the LLD for a particular measurement system shall be based on the actual observed variance of the background counting rate or the counting rate of the blank samples, as appropriate, rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry, the 1:;>ackground shall include the typical contribution of other radionuclides normally present in the samples. Typical values of E, V, and Y should be used in the calculation.

CY-Gl-170-300 Revision 33 Page 20 of 120 The background count rate is calculated from the background counts that are determined to be within +/- one FWHM energy band about the energy of the gamma ray peak used for the quantitative analysis for this radionuclide.

(b} A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analysis, each batch shall be isolated then thoroughly mixed according to the following: t *

A & B Monitor Tanks shall be mixed by recirculating for at least 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months .

The High Conductivity Waste Tank (HCWT) shall be mixed by running the pump and air blower for at least 1O minutes. HCWT isolation does not include periodic pumpdown of the AVT sample sink sump.

Steam Generator batch releases during shutdown cannot be adequately mixed by recirculating. A sample shall be taken during mid-release and analyzed.

The outside Condensate Storage Tank cannot be adequately mixed by recirculating. A sample shall be taken during mid-release and analyzed.

The sludge lance trailer shall be mixed by recirculating for at least 30 minutes.

{c) A composite sample is orie in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharged and in which the method of sampling employed results in a specimen which is representative of the liquids released.

Decay corrections are calculated from the midpoint of the sampling period.

(d) The principal gamma emitters for which the LLD specification will apply are exclusively the following radionuclides:

Mn-54, Fe-59, Co-58, Co-60, Zn-65, Cs-134, Cs-137 and Ce-141 {Ce-141 shall be measured to a LLD of 5.0E-06).

This list does not mean that only these nuclides are to be detected and reported.

Other nuclides which are measurable and identifiable, together with the above nuclides, shall also be identified and reported. Nuclides which are below the LLD for the analyses should be reported as less than the LLD and should not be reported as being present at the LLD level. The less than values should not be used in the required dose calculations.

(e) A continuous release is the discharge of liquid wastes of a non-discrete volume; e.g., from a volume or system that has an input flow during the continuous release. Decay corrections will be calculated based on all samples collected during the release.

Service water sample frequency for H-3, gross alpha, Sr-89, Sr-90, and Fe-55 will be increased to produce a composite whenever principal gamma emitters are detected. The analysis frequency will be monthly for H-3 and gross alpha, and quarterly for Sr-89, Sr-90, and Fe-55 whenever principal gamma emitters are detected.

CY-Gl-170-300 Revision .33 Page 22 of 120 4.4 LIQUID EFFLUENTS .RELEASE POINTS There are three normal release points for liquid radioactive effluents from the plant that empty into the discharge canal. These are the Radwaste Treatment Discharge, Retention Tank discharge and the All Volatile Treatment Discharge.

Each of these is a monitored release line that can be isolated before the release reaches the discharge canal. There is also a release point for the service water lines used for cooling the heat exchangers that is a monitored release line but is not isolatable. If there is an alarm on the service water monitor, it is necessary to sample each heat exchanger separately to determine which has a leak and then isolate the affected heat exchanger. The pressure of the service water system flow would normally force water from the clean service water side into the contaminated side of the heat exchanger. Dilution of liquid effluent is provided by the discharge canal. The discharge canal flow is nominally 1. 7E+05 gpm for each circulating water pump. During operating periods, two circulating water pumps are in operation. During shutdown periods, one circulating water pump is operated. If neither circulating water pump is operable, dilution is provided by operation of one to three service water pumps which provide nominally 5.3E+03 gpmeach.

CY-Gl .. 170~300 Revision 33 Page 23 of 120 4.5 LIQUID EFFLUENTS MONITOR SETPOINTS Alarm and/or trip setpoints for radiation monitors on each liquid effluent line are required. Precautions, limitations and setpoints applicable to the operation of Ginna Station liquid effluent monitors are provided in plant procedure P-9 RAD/A TION MONITORING SYSTEM. Setpoint values are calculated to assure that alarm and trip actions occur prior to exceeding ten times the effluent concentration of Appendix B, Table 2, Column 2 of 10 CFR 20.1001 - 20.2402 at the release point to the unrestricted area. For added conservatism 1 liquid effluent release rates are administratively set so that only fractions of the applicable maximum effluent concentrations can be reached in the discharge canal.

The Calculated alarm and trip action*setpoints for each radioactive liquid effluent line monitor and flow determination must satisfy the following equation:

Equation (1)

Where:

C = the effluent concentration which implements ten times 10 CFR 20 limit for unrestricted areas, in µCi/ml.

c = the setpoint of the radioactivity monitor measuring the radioactivity concentration in the discharge line prior to dilution and subsequent release, in µCi/ml.

F = the dilution water flow as determined prior to the release point, in volume per unit time.

f = the liquid waste flow as measured at the discharge point, in volume per unit time, in the same units as F.

Liquid effluent batch releases from Ginna Station are discharged through a liquid waste disposal monitor. The liquid waste stream (f) is diluted by (F) in the plant discharge canal before it enters Lake Ontario.

CY-Gl-170-300 Revision 33 Page 24 of 120 The limiting batch release concentration (c) corresponding to the liquid waste

monitor setpoint is calculated from the above expression. Since the value of (f) is very small in comparison to (F), and tritium cannot be accounted for, the expression becomes:

cs c; x 0.4 (1-TCF)

Equation (2)

Where:

C = 1O x the allowable concentration of Cs-137 as given in Appendix 8, Table 2, Column 2 of 10 CFR 20, 1 x 10*5. This value is normally more restrictive than the calculated mixed isotopic release concentration. A weighted average, excluding Sb-125, from 1998 data indicated a* release concentration of 1 .15 x 1o*5 µCi/ml. (See DA-RP-99-078). This should be reviewed as an annual basis, and the more conservative value between the two be utilized.

F = the dilution flow assuming operation of only 1 circulating water pump (170,000 gpm).

c = the limiting batch release concentration corresponding to the liquid monitor setpoint f = the maximum waste effluent discharge rate through the designated pathway.

0.4 = a conservatism based on the possibility of 2 liquid discharges occurring simultaneously, minus 0.2 (Total Instrumental Uncertainty) eg: (limit - 0.2 TIU/2)

TCF = the Tritium Correction Factor, based on the maximum concentration of diluted RCS H-3, divided by H-3 E.C.L. The maximum UFSAR RCS tritium concentration is 3.5 µCi/ml. The monitor setpoint against gamma emitters must be reduced proportional to the ratio of tritium in the waste stream, to which the monitor will not respond.

CY-Gl-170-300 Revision 33 Page 25 of 120

The limiting release concentration (c) is then converted to a set-point count rate by the use of the monitor calibration factor determined per the individual monitor calibration procedure. The expression becomes:

Setpoint (cpm) = c (1.1Cilml)

Cal Factor (1.1Cilmllcpm)

Equation (3)

Example (Liquid Radwaste Monitor R-18):

Assuming, for example, that the maximum pump effluent discharge rate (f) is 90 gpm and the RCS tritium concentration is 3 µCi/ml, then the limiting batch release concentration (c) would be determined as follows:

. J\ < 1E -05 (µ.Ci/ml) x 170, 000 (gp m) 0 4 [l _ ti9o ]

c ( µ. C11 m,,_ 90gpm

x

x lE-2 cs 6.39E-3 (.'u Ci/ml)

The monitor R-18 alarm and trip setpoint (in cpm) is then determined utilizing the monitor calibration factor calculated in plant procedure CPI-MON-R18. Assuming a calibration factor of 1.2 E-8 (1.101ml) cpm and a limiting batch release concentration determined above, the alarm and trip setpoint for monitor R-18 would be:

6.39E - 3(µ.c_Uml) = 533 E + 05 cpm above backgro1.1nd 12E-8µ.Qlml cpm The setpoint values for the containment Fan Cooler monitor (R-16), Spent Fuel Pit Heat Exchanger Service Water Monitors (R-20A and R-208), Steam Generator Slowdown Monitor

{R-19), the Retention Tank Monitor (R-21, and the All volatile Treatment Waste Discharge Monitor (R-22) are calculated in a similar manner using equation (2),

substituting appropriate values of (f) and the corresponding calibration factor.

Effluent Monitor Warning alarm setpoints are set at one-half of the trip setpoint.

With all calculations equal this is a warning that 20% of the release limit has been reached at a single release point.

CY-Gl-170-300 Revision 33 Page 26 of 120 4.6 LIQUID EFFLUENT RELEASE CONCENTRATIONS Liquid batch releases are controlled individually and each batch release is authorized based upon sample analysis and the existing dilution flow in the discharge canal. Plant procedures establish the methods for sampling and analysis of each batch prior to release. A release rate limit is calcul8:ted for each batch based upon analysis, dilution flow and all procedural conditions being met before it is authorized for release. The waste effluent stream entering the discharge canal is continuously monitored and the release will be automatically terminated if the preselected monitor setpoint is exceeded. A release may continue subject to grab sample analysis and monitoring in accordance with Table 6.1-1.

The equation used to calculate activity is:

CV-Gl-170-300 Revision 33 Page 27 of 120 4.7 LIQUID EFFLUENT _DOSE The dose contribution received by the maximally exposed individual from the ingestion of Lake Ontario fish and drinking water is determined using the following methodology. These calculations will assume a near field dilution factor of 1.0 in evaluating the fish pathway dose, and an average annual dilution factor of 200 between the plant discharge and the Ontario Water District drinking water intake located approximately 2220 meters northeast (53 degrees) of the discharge canal. The average annual dilution factor of 200 was derived from the drift and dispersion study documented in reference 10.4.

Dose contributions from shoreline recreation, boating and swimming have been shown to be negligible in the Appendix I dose analysis, reference 10.5, and do not need to be routinely evaluated. Shoreline sediment samples downstream from the plant will be collected at least semi-annually for the Radiological Environmental Monitoring Program, as a conservatism. Presence of radioactivity above background will result in calculation of dose contribution from these pathways.

There is no known human consumption of shellfish from Lake Ontario; therefore, this pathway is not taken into consideration in dose calculations.

The dose contribution to an individual will be determined to ensure that it complies with the specification of Section 4.2.1 (Dose - Controls). Offsite receptor doses will be determined for the limiting age group and organ, unless census data show that actual offsite individuals are the limiting age group.

The following expression is used to calculate ingestion pathway dose contributions for the total release period from all radionuclides identified in liquid effluents released to unrestricted areas:

D~ = l: [Ai~ l: hti CV~]

2 J Equation (5)

Where:

D't = the cumulative dose commitment to the total body or any organ, t, from the liquid effluents for the summation of the total time period in mrem.

Lis for total number of hours of release.

j Atj = the length of the jth time period over which Cij and Fj are averaged for all liquid releases in hours.

CY-Gl-170-300 Revision 33 Page 28 of 120 Cij = the average concentration of radionuclide i in undiluted liquid effluent during time period tj from any liquid release in µCi/ml.

Ai-r = the site-related ingestion dose commitment factor to the total body or any organ,,:, for each identified principal gamma and beta emitter in mrem/hr per µCi/ml. See equation (6).

Fi = the discharge canal dilution factor for Cij during any liquid effluent release, defined as the ratio of the maximum undiluted liquid waste flow during release to unrestricted receiving waters. The dilution factor will depend on the number of circulation pumps operating and, during icing conditions, the percentage opening of the recirculating gate. Reference curves are presented in plant procedure CH-RETS-LIQ-RELEASE. .

Air= k 0 ( Uw !Dw + Up BFi) DFir Equation (6)

Where:

Ai, = the site-related ingestion dose commitment factor to the total body or to any organ, -c, for each identified principal gamma and beta emitter in mrem/hr per µCi/ml.

k0 = the units conversion factor, 1.14E+05 = 1.0E+06 pCi/µCi x 1.OE+03 ml/kg+ 8760 hr/yr Uw = a receptor person's water consumption by age group from Table E-5 of Regulatory Guide 1.109 Dw = the dilution factor from the near field area of the release point to potable water intake. The site specific dilution factor is 200. This factor is 1.0 for the fish ingestion pathway.

UF = a receptor person's fish consumption by age group from Table E-5 of Regulatory Guide 1.109 BFi = a bioaccumulation factor for nuclide, i, in fish in pCi/kg per pCi/L, from Table A-1 of Regulatory Guide 1.109

CY-Gl-170-300 Revision 33 Page 29 of 120 DFi't is the dose conversion factor for the ingestion of nuclide, i, for a receptor person in pre-selected organ, t, in mrem/pCi, from Tables E-11, E-12, E-13, E-14 of Regulatory Guide 1.109 The monthly dose contribution from releases for which radionuclide concentrations are determined by periodic composite sample analysis may be approximated by assuming an average monthly concentration based on the previous monthly or quarterly composite analysis. However, in the Annual Radioactive Effluent Release Report the calculated dose contributions from these radionuclides shall be based on the actual composite analysis.

Example:

Computing the dose to the whole body via the fish and drinking water pathways, assuming an initial Cs-137 discharge concentration of 3.0E-04 µCi/ml:

Given the following discharge factors for example, where:

6.tj = 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months , the duration of the release Cij = 3.0E-04 µCi/ml Fj = liquid waste flow = 20 gpm (dilution flow}(z) 170,000 gpm z = Near field dilution = 1.0 for Ginna Dw= 200 and, taking the following values from Regulatory Guide 1.109 which concern the critical receptor, which is considered to be the child in this case:

Uw = 51 O I/year UF = 6.9 kg/year BFi = 2000 pCi/kg per pCi/1 DFi = 4.62E-05 mrem/pCi Then, the site-related ingestion dose commitment factor, Ah, is calculated as follows:

CY-Gl-170-300 Revision 33 Page 30 of 120

= 1.14 E+05 [510+(6.9)(2000)]4.62 E-05 200 Air = 7.27 E+ 04 mr1m /hr per µ.Ci /ml And, the whole body dose to the child is then:

= (7.27 E+ 04)(1)(3.0 E-04)(1.2 E-04)

Dr= 2.6 E- 03 mrem to the whol1 body from Cs-137 The dose contribution from any other isotopes would then need to be calculated and all the isotopic contributions summed.

At all tir:r,es.

Note: For unplanned release of gaseous wastes, compliance with Section 5.2.1 (Dose Rate - Controls) may be calculated using annual average XIQ.

Compliance with Section 5.2.1 (Dose Rate - Controls) shall be determined by considering the applicable ventilation system flow rates. These flow rates shall be determined at the frequency required by Table 6.2-2.

5.2.3 ACTION

If the calculated dose rate of radioactive materials released in gaseous effluents from the site exceeds the limits of Section 5.2.1 (Dose Rate - Controls), measures shall be initiated to restore releases to within limits. The effluent continuous monitors listed in Table 6.2-1 that have provisions for the automatic termination of gas decay ta*nk, shutdown purge or mini-purge releases, shall be used to limit releases within the values established in Section 5.2.1 (Dose Rate - Controls) when monitor setpoint values are exceeded.

2. The dose rate due to radioactive materials, other than noble gases, in gaseous effluents shall be determined to be within the above limits in accordance with the methodology and parameters of Section 5.7 of the ODCM by obtaining representative samples and performing analyses in accordance with the sampling and analysis program specified in Table 5-1.

CY-Gl-170-300 Revision 33 Page 33 of 120

5.2.5 BASES

This control is provided to ensure that the dose at any time at and beyond the SITE BOUNDARY from gaseous effluents will be within the annual dose limits of 10 CFR

20, Appendix B, Table 2, Column 1. These limits provide reasonable assurance

that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, either within or outside the SITE BOUNDARY, to annual average concentrations exceeding the limits specified in Appendix 8, Table 2 of 10 CFR 20. For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of the MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the SITE BOUNDARY. 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 gamma and beta dose rates above bac~ground to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrems/yearto the whole body or to less than or equal to 3000 mrems/year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrems/ye~r.

5.3.5 SURVEILLANCE REQUIREMENTS:

Cumulative dose contributions for the current calendar quarter and current calendar year for noble gases shall be determined in accordance with the methodology and parameters of Section 2.8 of the ODCM at least once every 3.1 days.

5.3.6 BASES

This control is provided to implement the requirements of Sections 11.B, Ill.A, and IV.A of Appendix I, 10 CFR 50. The control implements the guides set forth in Section I.B of Appendix I. The ACTION statements provide the required operating

CY-Gl-170-300 Revision 33 Page 35 of 120 flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the release of radioactive material in gaseous effluents to UNRESTRICTED AREAS will be kept 11 as low as reasonably achievable". The SURVEILLANCE REQUIREMENTS implement the requirements in Section Ill.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. The dose calculation methodology and parameters established in the ODCM for calculating the doses due to the actual release rates of radioactive noble gases in gaseous 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 10 CFR 50, Appendix I", Revision I, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors",

Revision I, July 1977. The ODCM equations for determining air doses at the SITE BOUNDARY are based on historical average atmospheric conditions.

5.3.7 CONTROLS

The dose to a MEMBER OF THE PUBLIC from 1-131, 1-133, tritium, and for all radioactive materials in particulate form with half-lives greater than eight days released with gaseous effluents from the site shall be limited to the following:

a Special Report shall be submitted to the Commission within 30 days which includes the following information:

1. Identification of the cause for exceeding the dose limit.

2. Corrective actions taken and/or to be taken to reduce releases of radioactive material in gaseous effluents to assure that subsequent releases will be within the above limits.

5.3.10 ACTION:

During any month when the calculated dose to a MEMBER OF THE PUBLIC exceeds 1148th the annual limit of Section 5.3.7 (Controls), (0.3 mrem), projected

CY-Gl-170-300 Revision 33 Page 36 of 120

cumulative dose contributions from gaseous effluents shall be determined for that month and at least once every 31 days for the next 3 months.

5.3.11 SURVEILLANCE REQUIREMENTS Cumulative dose contributions for the current calendar quarter and current calendar year for lodine-131, lodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days shall be determined in accordance with methodology and parameters of Section 5.8 of the ODCM at least once every 31 days.

5.3.12 BASES:

This control is provided to implement the requirements of Sections 11.C, Ill.A, and IV.A of Appendix I, 10 CFR 50. The control implements the guides set forth in Section 11.C of Appendix I. The ACTION statements provide the required

operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the release of radioactive material in gaseous effluents to UNRESTRICTED AREAS will be kept 11 as low as reasonably achievable 11

The SURVEILLANCE REQUIREMENTS implementthe requirements in Section Ill.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.' The dose calculation methodology and parameters established in the ODCM for calculating the doses due to the actual release rates of the subject materials in gaseous 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 10 CFR 50, Appendix I", Revision I, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors", Revision I, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate controls for lodine-131, lodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent upon the existing radionuclide pathways to man in the areas at or beyond the SITE BOUNDARY.

The pathways examined in development of the calculations were:

1. Individual inhalation of airborne radionuclides

2. Deposition of radionuclides onto green leafy vegetation with subsequent consumption by man

3. Deposition of radionuclides onto grassy areas where milk animals and meat producing animals graze, followed by human consumption of that milk and meat

CY-Gl-170-300 Revision 33 Page 37 of 120

5.4.1 CONTROLS

The annual (calendar year) dose or dose commitment to any MEMBER OF THE PUBLIC due to releases of radioactivity and to radiation from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems.

5.4.2 APPLICABILITY

At all times.

5.4.3 ACTION

With the calculated doses from the release of radioactive materials in gaseous effluents exceeding twice the limits of Sections 5.3.1 and 5.3.7 (Controls), prepare and submit to the Commission within 30 days a Special Report that. defines the corrective actions to be taken to reduce subsequent releases to prevent recurrence of exceeding the above limits and include scheduling for achieving conformance with the above limits. Calculations which include direct radiation contributions from the unit and from any radwaste storage shall be performed to determine total dose to a MEMBER OF THE PUBLIC. This Special Report, as_ defined in 10 CFR 20.405(c) shall 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 releases covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations. If the estimated dose(s) exceeds the above limits, and if the release condition resulting in violation of 40 CFR 190 has not already been corrected, the Special Report shall include a request for a variance in accordance with the provisions of 40 CFR 190.

Submittal of the report is considered a timely request, and a variance is granted until staff action on the request is complete.

5.4.4 ACTION

This report shall include an analysis which demonstrates that radiation exposure to all MEMBERS OF THE PUBLIC from the plant are less than the 40 CFR 190 limits.

Otherwise, the report shall request a variance from the commission to permit releases to exceed 40 CFR Part 190. Submittal of the report is considered a timely request by the NRC, and a variance is granted until staff action on the request is complete.

5.4.5 SURVEILLANCE REQUIHEMENTS:

1: Cumulative dose contributions from liquid and gaseous effluents shall be determined in accordance with Sections 5.3.5 and 5.3.11 (Surveillance Requirements) at least once every 31 days, in accordance with the methodology and parameters of Section 2.8 of the ODCM.

CY-Gl-170-300 Revision 33 Page 39 of 120

2. Cumulative dose contributions from direct radiation from the unit and from radwaste storage including ISFSI, shall be determined from environmental dosimeter data at least quarterly.

5.4.6 BASES

This control is provided to meet the dose limitations of 40 CFR 190 that have been incorporated into 10 CFR 20 by 46FR18525. The specification requires the preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrems to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems. 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 plant remains within twice the dose design objectives of Appendix I, and if direct radiation doses are kept small.

Cumulative direct radiation dose from environmental dosimeters shall be used to ensure that dose limits of 10CFR72.104 are met. The Special Report will 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 Special Report, it may be assumed that the dose contributions from other uranium fuel cycle sources is negligible. If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40 CFR 190, the Special Report with a request for a variance, {provided the release conditions resulting in violation of 40 CFR 190 have not already been corrected), in accordance with the provisions of 40 CR 190.11 and 10CFR 20.405c, is considered to be a timely request and fulfills the requirements of 40 CFR 190 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 the other requirements for dose limitation of 10CFR 20, as addressed in Section 4.1.1 {Radioactive Liquid Effluents - Controls) and Section 5.2.1 (Dose Rate - Controls). 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.

(b) Analyses shall also be performed when the monitor on the continuous sampler reaches its setpoint.

(c) Tritium grab samples shall be taken at least three times per week when the reactor cavity is flooded.

(d) The ratio of the sample flow rate to the sampled stream flow rate shall be known for the time period covered by each dose or dose rate calculation made in accordance with Sections 5.2.1, 5.3.1, and 5.3.7 (Controls).

This list does not mean that only these nuclides are to be detected and reported.

Other nuclides which are measurable and identifiable, together with the above nuclides, shall also be identified and reported.* Nuclides which are below the LLD for the analyses should not be reported as being present at the LLD level for that nuclide. When unusual circumstances result in LLDs higher than required, the reasons shall be documented in the Annual Radioactive Effluent Release Report.

When samples collected for 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months are analyzed, the corresponding LLDs may be increased by a factor of 10. This requirement for increased sample frequency does not apply if: (1) analysis shows that the DOSE EQUIVALENT 1-131 concentration in the reactor coolant has not increased more than a factor of 3; and (2) the noble gas monitor shows that effluent

CY~Gl"170*300 Revision 33 Page 42 of 120 activity has not increased more than a fl:).ctor of 3.

CY-Gl-170-300 Revision 33 Page 43 of 120 5.5 GASEOUS EFFLUENT RELEASE POINTS There are three release points continuously monitored for noble gases, containment vent, plant vent and air ejector. The containment vent and plant vent are also continuously monitored for radioiodines and particulates. Since the air ejector is a steam release point, continuous radioiodine and particulate monitoring is not required when the secondary coolant activity is less than 1.0E-04 µCi/gm. Flow rates through the vents are measured periodically. During shutdown, temporary trailers may be brought on site that also require monitoring and characterization of their releases, such as the CO2 decon trailer.

Quarterly plant measurements of one week duration for the particulate and iodine released in the steam by the air ejector demonstrate that sampling this pathway for particulate and iodine is not necessary since these releases are less than 0.1 % of the Plant Vent. The releases are correlated to blowdown activity for determining activity in steam releases. During shutdown and startup, special systems are in use that may release small amounts of radioactivity in steam releases. This is accounted for by using operational data and activity in the source of the steam.

Grab samples are obtained when practicable.

If an unmonitored release point is identified, a calculation is performed to determine the radioactivity that is released. The calculation includes a conservative estimate of source term if sample data is not available, and a conservative estimate of flow rate and duration if measurement of flow and duration are not available. If the release is continuous, it is included in the monthly report that accounts for releases from the site for calculating doses to the general public.

CY-Gl-170-300 Revision 33 Page 44 of 120 5.6 GASEOUS EFFLUENT MONITOR SETPOINTS Alarm and/or trip setpoints for specified radiation monitors are required on each noble gas effluent line from the plant. Precautions, limitations and setpoints applicable to the operation of Ginna Station gaseous effluent monitors are provided in plant procedure P-9. Setpoints are conservatively established for each ventilation noble gas monitor so that dose rates in unrestricted areas corresponding to 10 CFR Part 50 Appendix I limits will not be exceeded. Setpoints shall be determined so that dose rates from releases of noble gases will comply with Section 5.2.1 (Dose Rate - Controls).(1 ). Table 5-2 provides the gaseous and particulate meteorological assumption used in development of the P-9 setpoints.

The gaseous and particulate meteorological assumptions used in Table 5-2 were derived from legacy UFSAR analyses and are more conservative than the meteorological assumptions used to calculate routine effluent doses to critical receptors in the effluent management software.

The calculated alarm and trip action setpoints for each radioactive gaseous effluent monitor must satisfy the following equation:

Equation (7)

Where:

cv = setpoint in cpm Oiv = release rate limit by specific nuclide (i) in µCi/sec from vent (v) f= discharge flow rate in cfm .

k= units conversion factor in cc/sec/cfm K= calibration factor in µCi/cc/cpm]

The general methodology for establishing plant ventilation monitor setpoints is based upon a vent concentration limit in µCi/cc derived from site specific meteorology and vent release characteristics.

Additional radiation monitor alarm and/or trip setpoints are calculated for radiation monitors measuring radioiodines, radioactive materials in particulate form and to radionuclides other than noble gases. Setpoints are determined to assure that dose rates from the release of these effluents shall comply with Section 5.2.1 (Dose Rate - Controls)(2)

CY-Gl-170-300 Revision 33 Page 45 of 120 The release rate limit for noble gases shall be calculated by the following equation for total body dose: *

2 ~ ~ , , ,£..,. l 111 i

Equation (8)

Note: An occupancy factor of 1 is assumed. This may be modified following reviews of the area in question and by the following equation for skin doses:

Equation (9)

Where:

Oiv = the release rate of radionuclide (i) from vent (v) which results in a dose rate of 500 mrem/yr to the whole body or 3000 mrem/yr to the skin of the critical

receptor in µCi/ sec.

Ki = the total body dose factor due to gamma emissions for each identified noble gas radionuclide in mrem/yr per µCi/m3 from Tab-le 5-3.

Li = the skin dose factor due to beta emissions for each identified noble gas radionuclide in mrem/yr per µCi/m3 from Table 5-3.

Mi = the air dose factor due to gamma emissions for each identified noble gas radionuclide in mrad/yr per µCi/m3 from Table 5-3. Unit conversion constant of 1 .1 mrem/mrad converts air dose to skin dose.

(X/O)v = the highest calculated annual average dispersion parameter for estimating the dose to the critical offsite receptor from vent release point (v) in sec/m 3 . The (X/O)v is calculated by the method described in Regulatory Guide 1.111.

Noble gas monitor setpoints are conservatively set according to procedure P-9, RAD/A TION MONITORING SYSTEM, to correspond to fractions of the applicable 10 CFR Part 20 dose limits for unrestricted areas. Fractions are small enough to

CY-Gl-170-300 Revision 33 Page 46 of 120 assure the timely detection of any simultaneous discharges from multiple release points before the combined downwind site boundary concentration could exceed

allowable limits. Additional conservatism is provided by basing these setpoints upon instantaneous downwind concentrations. Release rates during the remainder of a given year, combined with any infrequent releases at setpoint levels, would result in only a very small fraction of the 10 CFR Part 20 annual limits.

Historically, xenon-133 has been the principal fission product noble gas released from all vents and is appropriate for use as the reference isotope for establishing monitor setpoints. The whole body dose will be limiting, and the Xe-133 release rate limit is calculated by substituting the appropriate values into equation (8). After the release rate limit for Xe-133 is determined for each vent, the corresponding vent concentration limits are calculated based on applicable vent flow rates. During periods of high make-up water usage, argon-41 from air saturated make-up water becomes the principle radiogas of concern and may be used as the reference isotope for establishing setpoints. Calibration factors in µCi/cc per cpm are used to convert limiting vent concentrations to count rates.

Example: Plant Vent Monitor, R-14 Using Xe-133 as the controlling isotope for the setpoint and assuming a measured activity of 2.66E-04 µCi/cc and a ratemeter reading of 4750 cpm above background, the efficiency can be calculated, using a measured vent flow of 7.45E+04 cfm, Ki from Table 5-3 of 2.94E+02 and a (X/O)v for the site boundary of 2.7E-06, the Release Rate Limit is calculated and then the setpoint determined.

Plant procedures establish the methods for sampling and analysis for continuous ventilation releases and for containment purge releases. Plant procedures also establish the methods for sampling and analysis prior to gas decay tank releases.

6.2.2 APPLICABILITY

As shown in Table 6.2-1 Note: The Radioactive Effluent Monitoring Instrumentation may be removed from service for short periods of time without the instrumentation being considered inoperable for weekly grab filter or cartridge changes or monthly/quarterly testing, with the exception of the R-1 OA, R-11, R-12 skid.

(b) Only radiation monitor R-14 has an isolation signal. If R-14AGAS is being used to monitor batch gas releases, the contents of the tank(s) may be released to the environment provided that prior to initiating the release:

1. At least two independent samples of the tank's contents are analyzed, and

2. At least two technically qualified members of the facility staff independently verify the release rate calculations and discharge valve lineup.

(c) Required in MODES 5 and 6.

(d) The mini-purge system allows the release of Containment atmosphere through the plant vent. 10 CFR 100 type releases via mini-purge are limited by an isolation signal generated from Safety Injection. 10 CFR 20 releases through the mini-purge are considered to be similar to other plant ventilation releases and are monitored by R-14, R-13 and R-10B. R-14A may be used as a substitute for R-14 since automatic isolation i$ available from the R-11 or R-12 monitors if the activity in Containment increases. Therefore, either R-11 or R-12 is required to sample Containment during a mini-purge release. Automatic isolation of mini-purge for 10 CFR part 20 type releases 1s considered unnecessary due to the low flow associated with mini-purge, the continuous monitoring from R-11 or R-12 and the original measurement before the purge begins. To ensure the Containment sample monitored by R-11 or R-12 is representative of the containment atmosphere, at least one containment recirculation fan is required to be in operation during mini-purge operation.

(e) If the R-1 OA, R-11, R-12 skid is not OPERABLE, it is possible to substitute the R-

1OB,R-13, R~14 skid when the R-14A skid is OPERABLE. The setpoints for the R-1OA, R-11, R-12 skid would be used. There would be no automatic containment isolation capability from the radioactive effluent monitoring instrumentation when using R-108, R-13, R-14 skid for containment leakage measurements. This cannot be used if Containment Ventilation Isolation is required.

(f) If containment ventilation isolation instrumentation is required by LCO 3.3.5 for core alteration or movement of irradiated fuel in containment, R-12A skid cannot be used in place of the R-1 OA, R-11, R-12 skid. *

(g) Required only when Air Ejector is operating.

(h) Gaseous effluent monitors are not considered inoperable due to changes in ventilation flow. Reduced flow in the ventilation makes the monitor setpoint more conservative.

Action 1 If the number of OPERABLE channels is less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue provided iodine and particulate samples are continuously collected with alternate sampling equipment as required in Table 6.2-1. This should be completed within one hour.

Action 2 If the number of OPERABLE channels is less than required by the Minimum Channels OPERABLE requirement, continuous effluent releases via this pathway may continue provided grab samples are taken and analyzed for isotopic activity at least once per 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months .

If the secondary activity is > 1.0E-04 µCi/gm, effluent releases via this pathway may continue for up to 31 days provided grab samples are taken every 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months and analyzed within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

CY-Gl-170-300 Revision 33 Page 83 of 120 7.3 SOLID RADWASTE SYSTEM

7.3.1 CONTROLS

1. The solid radwaste system shall be used as applicable in accordance with the Process Control Program for the solidification and packaging of radioactive waste to ensure meeting the requirements of 10 CFR 71 prior to shipment of radioactive wastes from the site.

7.3.2 APPLICABILITY

At all times.

7.3.3 ACTION

If the packaging requirements of 10 CFR 71 are not satisfied, suspend shipments of deficiently packaged solid radioactive wastes from the site until appropriate corrective measures have been taken.

CY-Gl-170-300 Revision 33 Page 84 of 120 7.4 CONFIGURATION CHANGES 7.4. 1 CONTROLS:

Major changes to the Radioactive Waste Treatment Systems, (Liquid, Solid, and Gaseous), shall be reported to the Commission by the inclusion of a suitable discussion or by reference to a suitable discussion of each change in the Annual Radioactive Effluent Release Report for the period in which the changes were made. Major changes to Radioactive Waste Treatment Systems, (Liquid, Gaseous and Solid), shall include the following:

1. Changes in process equipment, components and structures from those in use (e.g., deletion of evaporators and installation of demineralizers);

2. Changes in the design of Radioactive Waste Treatment Systems that could significantly alter the characteristics and/or quantities of effluents released;

3. Changes in system design which may invalidate the accident analysis (e.g., changes in tank capacity that would alter the curies released).

Note: The Radioactive Waste Treatment Systems, are those systems used to n:1inimize the total activity released from the site.

Note: Changing the filters used, replacement resins or minor modifications (pipe or valve dimensions or manufacturers) due to maintenance activities would not be considered a major change.

7.4.2 APPLICABILITY

At all times.

7.4.2 ACTION

The discussion of each change shall contain:

1. a summary, in accordance with 10 CFR 50.59, of the evaluation that led to the determination that the change could be made;

2. sufficient detailed information to support the reason for the change;

3. a detailed description of the equipment, components and processes involved and the interfaces with other plant systems;

4. an evaluation of the change which shows the predicted releases of radioactive materials in liquid and gaseous effluents from those previously predicted;

5. an evaluation of the change which shows the expected maximum exposures to individuals in all UNRESTRICTED AREAS and to the MEMBERS OF THE PUBLIC from those previously estimated;

6. documentation of the fact that the change was reviewed and found acceptable by the Plant Operations Review Committee.

CY-Gl-170-300 Revision 33 Page 85 of 120 7.5 PROCESS CONTROL PROGRAM

a. The Process Control Program (PCP) shall be a document outlining the method of processing wet or dry solid wastes and for solidification of liquid wastes. It shall include the process parameters and evaluation methods used to assure meeting the requirements or 10 CFR Part 71 prior to shipment of containers of radioactive waste from the site.

,b. Licensee may make changes to the PCP and shall submit to the Commission with the Radioactive Effluent Release Report for the period in which any change(s) is made a copy of the new PCP and a summary containing:

1. sufficiently detailed information to support the rationale for the change;

2. a determination that the change will not reduce the overall conformance of the solidified waste product to existing criteria for solid wastes; and

3. documentation of the fact that the change has been reviewed and found acceptable by the onsite review function.

c. Licensee initiated changes shall become effective after review and '

acceptance by the Plant Operation Review Committee.

CY-Gl-170-300 Revision 33 Page 86 of 120 8.0 RADIOLOGICAL ENVIRONMENTAL MONITORING 8.1 MONITORING PROGRAM

8.1.1 CONTROLS

The Radiological Environmental Monitoring Program (REMP) shall be conducted as specified in Table 8-1 at the locations given in Figures 8-1, 8-2, 8-3 and 8-4.

8.1.2 APPLICABILITY

At all times.

8.1.3 ACTION

1. If the radiological environmental monitoring program is not conducted as specified in Table 5-1, prepare and submit to the Commission, in the Annual Radiological Environmental Operating Report, a description of the reasons for not conducting the program as required and the plans for preventing a recurrence. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal availability, or to malfunction of automatic sampling equipment. If the latter, efforts shall be made to complete corrective action prior to the end of th.e next sampling period. Sampling periods for this specification are usually of one week duration. If continuous water sampling equipment is out of service, the 120 minute aliquot sampling period does not mean that grab samples must be taken every 120 minutes, but one grab sample once each week is sufficient until the automatic sampling equipment is restored to service.

2. If the level of radioactivity as a result of plant effluents in an environmental sampling medium at one or more of the locations specifietf exceeds the reporting levels of Table 5-4 when averaged over any calendar quarter, prepare and submit to the Commission within 30 days from receipt of the laboratory analysis a Special Report that identifies the cause(s) for exceeding the limit(s) and defines the corrective actions to be taken to reduce radioactive effluents so that the potential annual dose* to a MEMBER OF THE PUBLIC is less than the calendar year limits of Sections 4.2.1, 5.3.1, and 5.3.7 (Controls).

When more than one of the radionuclides in Table 5-4 are detected in the*

sampling medium, this report shall be submitted if:

concentration (1 )+ concentration (2) + =} > 10 limit level (1) limit level (2) *

When radionuclides other than those in Table 5-4 are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose to a MEMBER OF THE PUBLIC from all radionuclides is greater than

CY-Gl-170-300 Revision 33 Page 87 of f20 the calendar year limit of Sections 4.2.1, 5.3.1, and 5.3.7 (Controls). This report is not required if the measured level of radioactivity was not the result of plant effluents; however, in such an event, the condition shall be reported and described in the Annual Radiological Environmental Operating Report.

The methodology and parameters used to estimate the potential annual dose to a MEMBER OF THE PUBLIC shall be indicated in this report.

4. With milk or fresh leafy vegetable samples unavailable from one or more of the sampling locations indicated on Figure 8-2, a discussion shall be

.included in the Annual Radiological Environmental Operating Report which identifies the cause for the unavailability of samples and identifies locations for obtaining replacement samples. In selecting replacement samples, consider the implications of collecting samples outside the normal REMP ingestion pathway. In particular, recognize that perennial vegetation from relatively undisturbed areas is likely to have higher concentrations of Cs-137 than vegetation grown in soil that is regularly disturbed by cultivation and harvesting activities. If a milk or leafy vegetable sample location becomes unavailable, the location from which samples were unavailable may then be deleted provided that a comparable location is added to the radiological environmental monitoring program as described in the ODCM, unless no other sample location is available.

8.1.4 SURVEILLANCE REQUIREMENTS:

The radiological environmental samples shall be collected pursuant to Table 8-1 from the specific locations given in the table and figure(s) given in the ODCM, and shall be analyzed pursuant to the requirements of Table 8-1 and the detection capabilities required by Table 8-3. *

8.1.5 BASES

The REMP required by this Control provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures to MEMBERS OF THE PUBLIC resulting from plant operation. This monitoring program implementsSection IV.B.2 of Appendix I to1 O CFR 50, and thereby supplements the RETS 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 the modeling of the environmental exposure pathways.

Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring, Revision 1, November 1979.

Deviations are permitted from the required sampling schedule if specimens are unobtainable due to circumstances such as hazardous conditions, seasonal unavailability, inclement weather, and malfunction of automatic sampling equipment. If specimens are unavailable due to sampling equipment malfunction, effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the next Annual Radiological Environmental Operating Report. It is recognized that, at times, it may not be possible or practicable to continue to obtain samples of the media of choice at the most desired location or time. In these instances suitable alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the radiological environmental monitoring program as described in the ODCM. Submit in the next Annual Radioactive Effluent Release Report documentation for a change in the ODCM including a revised figure(s) and .table for the ODCM reflecting the new location(s) with supporting information identifying the cause of the unavailability of samples for the pathway and justifying the selection of the new Iocation(s) for obtaining samples.

(b) One or more instruments, such as a pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. For the purposes of this table, a dosimeter is considered to be one phosphor; two or more phosphors in one packet are considered to be two or more dosimeters. Film badges shall not be used for measuring direct radiation. The 39 stations is not an absolute number. The number of direct radiation monitoring stations may be reduced according to geographical limitations; e.g., some sectors may be over water so that the number of dosimeters may be reduced accordingly. The frequency of analysis or readout for dosimetry systems will depend upon the characteristics of the specific system used and should be selected to obtain optimum dose information with minimal fading.

(c) Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 or more hours after sampling to allow for radon and thoron daughter decay.

If gross beta activity in air particulate samples is greater than 10 times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

(d) Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.

CY-Gl-170-300 Revision 33 Page 91 of 120 (e) The "control sample" shall be taken at a distance beyond significant influence of the discharge. The "indicator sample" shall be taken in an area beyond but near the mixing zone.

(f) A composite sample is one in which the quantity (aliquot) of liquid sampled is proportional to the quantity of flowing liquid and in which the method of sampling employed results in a specimen that is representative of the liquid flow. In this program composite sample aliquots shall be collected at time intervals that are very short (e.g., hourly) relative to the compositing period (e.g., monthly) in order to assure obtaining a representative sample.

(g) The dose shall be calculated for the maximum organ and age group, using the methodology and parameters in the OCDM.

CY-Gl-170-300 Revision 33 Page 92 of 120 8.2 ENVIRONMENTAL MONITOR SAMPLE LOCATIONS All sample locations are specified on Table 8-2, a list of direction and distance to sample points. Indicator and control samples required by the environmental program are noted by an I or a C.

Figure 8-1 shows the onsite* sample locations for airborne particulates, radioiodine and direct radiation. Also indicated on Figure 8-1 is the onsite vegetable garden, as well as the placement of post accident dosimeters, locations 2 -7 and 13 -24.

Dosimeter locations 2-7 are co-located with the air monitor samplers. The onsite garden is located in the SE sector near the closest resident who is the real maximally exposed individual, rather than in the ESE sector which has the highest D/Q.

Figure 8-2 gives the location of the milk herds near the plant. On this map is also included the Ontario Water District intake pumping station where lake water is sampled prior to treatment.

Figure 8-3 shows the offsite control locations for direct radiation as measured by dosimeters.

Figure 8-4 shows the offsite sample locations for airborne particulates, and radioiodine. Sample stations 9 and 11 are situated near population centers, Webster and Williamson, located approximately 7 miles from the Ginna Site.

Dosimeter locations 8 - 12 are co-located with air monitor samplers.

Onsite refers to the area surrounding the Ginna Plant bounded by Ginn a property lines. Offsite refers to the area beyond the immediate Ginna property.

Revision 33 Page 110 of 120 8.3 LAND USE CENSUS 8.3.1. CONTROL A Land Use Census shall be conducted annually between June 1 and October 1 ,

and shall identify within a distance of 5 miles the location in each of the 16 meteorological sectors of the nearest milk animal, the nearest residence, and the nearest garden of greater than 500 square feet producing broad leaf vegetation.

(In lieu of a garden census, broad leaf vegetation sampling of at least three different kinds of vegetation may be performed in an onsite garden located in the meteorological sector with the highest average annual growing season deposition parameter (D/Q) OR another location with a higher D/Q than the location of the maximally exposed individual.)

8.3.2 APPLICABILITY

At all Times.

8.3.3 ACTION

With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment greater than the values currently being calculated in Section 5.3.11 (Surveillance Requirements) of the ODCM, identify the new location(s) in the next Annual Radioactive Effluent Release Report.

With a Land Use Census identifying a location(s) that yields a calculated dose or dose commitment (via the same exposure pathway) 20% greater I

than at a location from which samples are currently being obtained in accordance with Section 8.1.1 (Radiological Environmental Monitoring -

Controls), add the new location(s) within 30 days to the REMP described in the ODCM, if permission from the owner to collect samples can be obtained and sufficient sample volume is available. The sampling location(s), excluding Control location(s), having the lowest calculated dose or dose commitment(s), via the same exposure pathway, may be deleted from this monitoring program after October 31 of the year in which this Land Use Census was conducted. Submit in the next Annual Radioactive Effluent Release Report documentation for a change in the ODCM including a revised figure(s) and table(s) for the ODCM reflecting the new location(s) with information supporting the change in sampling location(s).

8.3.4 SURVEILLANCE REQUIREMENTS The Land Use Census shall be conducted between June 1 and October 1 of each year using a method that will best provide the necessary information such as by door-to-door survey, vehicular survey, aerial survey, or by consulting local agricultural authorities. The results of the Land Use Census shall be included in the Annual Radiological Environmental Operating Report pursuant to Section 9.1 oftheODCM.

CY-Gl-170-300 Revision 33 Page 111 of 120

8.3.5 BASES

This specification is provided to ensure that changes in the use of areas at or beyond the SITE BOUNDARY are identified and that modifications to the REMP given in the ODC Mare made if required by the results of this census. Information from methods such as the door-to door survey, vehicular survey, aerial survey, or from consulting with local agricultural authorities shall be used. This census satisfies the requirements of SectionlV.B.3 of Appendix I to 10 CFR 50.

Restricting the census to gardens of greater than 500 square feet 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) there was a vegetation yield of 2 kg/m2.

CY-Gl-170-300 Revision 33 Page 112 of 120 8.4 JNTERLABORATORY COMPARISON PROGRAM 8.4.1 CONTROL Analyses shall be performed on all radioactive materials supplied as part of an lnterlaboratory Comparison Program, that correspond to samples required by the REMP, and that has been approved by the Commission, if such a program exists.

8.4.2 APPLICABILITY

At all times.

8.4.3 ACTION

With analyses not performed as required above, report the corrective actions taken to prevent recurrence to the Commission in the Annual Radiological Environmental Operating Report pursuant to Section 8.4.1 (lnterlaboratory Compa.rison Program -

Control) of the ODCM.

8.4.4 SURVEILLANCE REQUIREMENTS The lnterlaboratory Comparison Program is described in and implemented by procedure CH-QC-INTERLAB. A summary of the results obtained as part of the above required lnterlaboratory Comparison Program shall be included in the Annual Radiological Environmental Operating Report pursuant to Section 8.4.1 (lnterlaboratory Comparison Program - Control) of the ODCM.

8.4.5 BASES

The requirement for participation in an approved lnterlaboratory Comparison Program i$ provided to ensure that in.dependent checks on the precision and accuracy of the measurements of radioactive materials 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 to10 CFR 50.

The Radiological Environmental Operating Report and the Annual Radioactive Effluent Release Report will be prepared and submitted to the U.S. Nuclear Regulatory Commission, Document Control Desk, Washington, D.C. 20555 and a copy to the Regional Administrator of the USN RC, Region I..

CY -G 1-170-300 Revision 33 Page 117 of 120 9.3 SPECIAL REPORTS Guidance is given for each of these reports in the applicable Control. The following general guidelines are included here for calculating dose to an exposed individual or the MEMBERS OF THE PUBLIC for preparation of Special Reports:

a. The maximally exposed real MEMBER OF THE PUBLIC will generally be the same individual considered in the ODCM.

b. Dose contributions to the maximally exposed individual need only be considered to be those resulting from the Ginna plant itself. All other uranium fuel cycle facilities or operations are of sufficient distance to contribute a negligible portion of the individual's dose.

c. For determining the total dose to the maximally exposed individual from the major gaseous and liquid effluent pathways and from direct radiation, dose evaluation techniques used in preparing the Special Report will be those described in the ODCM, or other applicable methods where appropriate.

d. The contribution from direct radiation may be estimated by effluent .

dispersion modeling or calculated from the results of the environmental monitoring program for direct radiation.
