• Basis Liquid Effluent Concentration This specification 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 Part 20, Appendix B, Tabl.e II, Column 2. This limitation provides additional assurance that the levels of radioactive materials in bodies of water~ unrestricted areas will result in exposures within (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to the maximum exposed member of the public and (2) the limits of 10 CFR Part 20.106(e) 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 methods.described in International Commission on Radiological Protection (ICRP) Publication

I ( l I I l I I I I I i I J TS 3 .11-14 Liquid Effluent Dose This specification is provided to implement the requirements of Sections II.A, III.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.A of Appendix I. The Specific'ations 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 will be kept "as low as is reasonably achievable." The dose calculations in the ODCM implement the requirements in Section III.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 the maximum exposed member of the public through 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 liq"Hid 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 Part 50, Appendix I," 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. This specification applies to the release of liquid effluents from each reactor at the site. For units with shared radwaste treatment systems, the liquid effluents from the shared system are proportioned among the units sharing that system.

TS 3.11-15 Liquid Radwaste Treatment The requirement that the appropriate portions of this system be used, when specified, provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable".

This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section II.D of Appendix I to 10 CFR Part 50. The specified limits 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 II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

Gaseous Effluents Dose Rate This s~ecification is provided to ensure that the dose at any time at and beyond the site boundary from gaseous effluents from all units on the site will be within the annual dose limits of 10 CFR Part 20. The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, Appendix B, Table II, Column 1. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of the maximum exposed member of the public, either within or outside the site boundary to annual average concentrations exceeding the limits specified in Appendix B, Table II of 10 CFR Part 20 (10 CFR Part 20.106(b)).

For the maximum exposed members of the public, who may at times be within the site boundary the occupancy of the individual will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the site boundary.

The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above

• TS 3.11-16 background to an individual at or beyond the site boundary to less than or equal to 500 mrems/year to the total 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/year.

This specification applies to the release of gaseous effluents from all reactors at the site. For units with shared radwaste treatment systems, the gaseous effluents from the shared system are proportioned among the units sharing that system.

Dose -Noble Gases This specification is provided to implement the requirements of Sections II.B, III.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Condition for Operation implements the guides set forth in Section II.B of Appendix I. The Specifications 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 gaseous effluents will be kept "as low as is reasonably achievable."

• TS 3.11-17 with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of the maximum exposed member of the public through appropriate pathways is unlikely to be substantially underestimated.

The dose calculations 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 Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Reieases from Light-Water Cooled Reactors," Revision 1, July 1977. The ODCM equations provided for de.termining the air doses at and beyond the site boundaTy are based upon the historical average atmospheric conditions.

Dose -I-131, Tritium, and Radionuclides In Particulate Form This specification is provided to implement the requirements of Sections II.C, III.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Conditions for Operation are the guides set forth in Section II.C of Appendix I. The Specification 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 materials in gaseous effluents will be kept "as low as is reasonably achievable." The ODCM calculational methods specified in the Surveillance Requirements in section 4.9 implement the requirements in Section III.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 the maximum exposed member of the public "

TS 3 .11-18 through appropriate pathways is unlikely to be substantially underestimated.

The ODCM calculational methods for calculating the doses due to the actual release rates of the subject materials 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 Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors," Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions.

The release rate specifications for I-131, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent on the existing radionuclide

~athways to man, in the areas at and beyond the site boundary.

The pathways that were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man. Gaseous Radwaste Treatment . . The requirement that the appropriate portions of these systems be used, when specified, provides reasonable assurance that the releases of radioactive

' materials in gaseous effluents will be kept "as low as is reasonably achievable".

This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objectives given in Section II.D of Appendix I to 10 CFR Part 50. The specified limits TS 3.11-19 governing the use of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Sections II.Band II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

Explosive Gas Mixture This specification is provided to ensure that the concentration of potentially explosive gas mixtures contained in the waste gas holdup system is maintained below the flammability limits of hydrogen and oxygen. Maintaining the concentration of hydrogen and oxygen below their flammability limits provides assurance that the.releases of radioactive materials will be controlled in conformance with the r.equirements of General Design Criterion 60 of Appendix A to 10 CFR Part 50. Gas Storage Tanks The tanks included in this specification are those tanks for which*the quantity of radioactivity contained is not limited directly or indirectly by another Technical Specification to a quantity that is less than .the quantity which provides assurance that in the event of an uncontrolled release of the tank's contents, the resulting total body exposure to an individual at the nearest exclusion area boundary will not exceed 0.5 rem in an event of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. Restricting the quantity of radioactivity contained in each gas storage tank provides assurance that in the event of an uncontrolled release of the tank's contents, the resulting total body exposure to an individual at the nearest exclusion area boundary will not exceed 0.5 rem. This is consistent with Branch Technical Position ETSB 11-5 in NUREG-0800, July 1981.

• TS 3.11-20 Total Dose This specification is provided to meet the dose limitations of 40 CFR Part 190 / that have now been incorporated into 10 CFR Part 20 by 46 FR 18525. The specification requires the preparation and submittal" of a Special Report whenever the calculated doses from plant radioactive effluents exceed twice. the design objective doses of Appendix I. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to the maximum exposed member of the public will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within the reporting requirement level. The Special Report will describe a course of action that should result in the limitation of the annual dose to the maximum exposed member of the public to within the 40 CFR Par~;190 limits. For the purposes of the Special 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 dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered.

If the dose to the maximum exposed member of the public is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR Part 190.11 and 10 CFR Part 20.405c, is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is completed.

The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in Specifications 3.11.A and 3.11.B. An individual is not sidered the maximum exposed 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.

• TS 3.11-21 Monitoring Program The radiological environmental monitoring program required by this fication provides measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of the maximum exposed members of the public resulting from the station operation.

This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 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 the 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 4.9-5 are considered optimum for routine environmental measurements in industrial laboratories.

It should be recognized that the LLD is defined as an.!. priori (before the fact) limit representing the capability of a measurement system and not as an.!. posteriori (after the fact) limit for 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 pursuant to Specifieation 6.6.

Land Use Census This specification is provided to ensure that changes in the use of areas at and beyond the site boundary are identified and that modifications to the radiological environmental monitoring program are made if required by the results of this census. The best .information from the door-to-door survey. aerial survey or 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 m 2 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. t similar to lettuce and cabbage) t and 2) a vegetation 2 yield of 2 kg/m. ;.

TABLE NOTATION TS 4.9-6 It should be recognized that the LLD is defined as an.!_ priori (before the fact) limit representing the capability of a measurement system and not as an.!. posteriori (after the fact) limit for a particular measurement.

bA batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analyses, each batch shall be isolated, and appropriate methods will be used to obtain representative sample for analysis.

cThe principal gamma emitters for which the LLD specification applies exclusively are the following radionuclides:

Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141, and Ce-144. This list does not mean that only these nuclides are to be detected and reported.

Other peaks that are measurable and identifiable, at levels exceeding the LLD, together with the above nuclides, shall also be identified and reported.

TABLE NOTATION TS 4.9-10 It should be recognized that the LLD is defined as an a priori (before the fact) l~mit representing the capability of a measurement system and not as an.!_ posteriori (after the fact) limit for a particular measurement.

bThe principal gamma emitters for which the LLD specification applies exclusively are the following radionuclides:

Kr-87, Kr-88, Xe-133, Xe-133m, Xe-135, Xe-135m, and Xe-138 for gaseous emissions and Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, Ce-141 and Ce-144 for particulate emissions.

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

Other nuclides with half life greater than 8 days, that are measurable and identifiable at the level above LLD, together with the above nuclides, shall also be identified and reported.

cSampling and analyses shall also be performed following shutdown, startup, or a thermal power change exceeding 15 percent of the rated thermal power which occurs within a one hour period.

Where: LLD is the "a priori" lower limit of detection as defined above (as picocuries per unit*mass or volume), 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),

TS 4.9-15 Eis the counting efficiency (as counts per disintegration), Vis the sample size (in units of mass or volume), 2.22 is the number of disintegrations per minute per picocurie, Y is the fractional radioc~emical yield (when applicable), is the radioactive decay constant for the particular radionuclide,.

and t for environmental samples is the elapsed time between sample collection (or end of the sample collection period) and time of counting Typical values of E, V, Y, and t should be used in the calculation.

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

Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions.

Occasionally background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.

In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report pursuant to Specification 6~6.3.b.

ATTACHMENT 2

• JUSTIFICATIONS FOR DEVIATING FROM NUREG-0472 REVISION 3

1. The Radiological Effluent Technical Specifications for Surry Power Station are based upon the Revision 3 of NUREG-0472 dated March 30, 1982. The information applicable to the Surry Power Station has been included in the format of the existing Surry Technical Specifications.

Although there might be some deviations from the text of the NUREG-0472, the intent of the same has been met in most of the cases. 2. The existing format of the Table of Contents is used to reflect RETS. 3. All the appropriate definitions have been included in the Surry RETS. 4. In Tables 3. 7-5 (a) and 4 .1-1 (a), the Turbine Building Sumps Effluent Line is not included because it is not a normal radioactive effluent pathway. The potential for unplanned and unmonitored releases of activity to the environment from the contamination of normally active systems was reviewed by the station staff in response to I. E. Bulletin No. 80-10. Subsequent NRC inspections have also addressed the above issue. As a result, Surry has flow rate recorders in building sumps empty. maintained per station committed to installing composite samplers and the storm drain effluents, to which the turbine This equipment has been installed and will be procedures.

The presence of the samplers limit the possibility of a potential accidental release, discharging from the station without adequately quantifying its magnitude.

The daily analysis of the storm drain's hourly composite sample, indicate that this system is a non-contaminated effluent pathway and not subject to normal station radioactive effluents.

In addition, Surry has taken steps to eliminate normally radioactive systems from discharging into the turbine building sumps. A recent design change re-routed the Piping Tunnel sump effluents into the Radwaste System, thus precluding turbine building sump contamination.

5. The Steam Generator Blowdown Effluent Line is not included in Tables 3.7-S(a) and 4.1-l(a) because it is not an effluent pathway. It is a closed loop system, recirculated through the condensate polisher.

Also, Radioactivity Recorders are deleted because they do not provide alarm/trip set point. 6. The flow monitoring instrumentation for the Discharge Canal requested in the surveillance Table 4.1-l(a), is deleted. Pump curves will be used to determine flow. 7. Tank Level Indicating Devices are not included in Table 4 .1-1 (a). The outside tanks contain overflow protection that discharges to the liquid waste system. 8. Action Statements in Table 3.7-S(a) meet the intent of the Action Statments in NUREG-0472.

• *

• 9. The channel functional test is not applicable to the Liquid Waste Flow Measuring Device in Table 4 .1-1 (a), nor the Process Vent and Vent-Vent Flow Rate Measuring Devices in Table 4 .1-1 (b), because they have no alarm/trip function.

The channel check, performed daily, verifies operability of the channel. 10. Channel functional test as defined in the Surry Technical Specification describes the current capability of the effluent monitoring system. The montoring system would require a lengthy backfit that is not deemed to be beneficial.

In addition, a channel check is performed every shift by an operator to determine the monitors operability.

11. In Tables 3.7-5(b) and 4.1-l(b), the nomenclature has been changed to describe Surry's effluent monitoring systems. The Waste Gas Holdup System has been changed to Process Vent System, Condenser Evacuation System to Condenser Air Ejector System and Auxiliary Building Ventilation System to Ventilation Vent System. The Containment Purge System and the Radwaste Area Ventilation System are part of the Ventilation Vent System. The Steam Generator Blowdown Vent System is no longer in use at Surry. 12. The Limiting Condition of Operation for the Liquid Hold-up Tanks has been deleted due to overflow protection of outside tanks and the absence of potable water supply downstream of station effluents.

13. Refueling Canal and Spent Fuel Pool Area exhaust is discharged to the Ventilation Vent System. The H-3 sampling frequency for this system -is stated in Table 4.9-2 of the submittal.

14. I-133 is not included in the monitoring and dosi calculations.

An assessmemnt of prior releases from Surry Power Station, including the four years from 1979 to 1982, indicates that I-133 release quantities on an annual basis contribute less than 1% to the radioactive pathway doses. A summary of the data is listed below. In an interagency NRC memorandum on Provisions for I-133 in RETS, dated November 29, 1982, the primary concern was in effluent release from BWR's.

The surveillance requirements on the Waste Gas Decay Tanks have been changed to once per month when the specific activity of the coolant is ~2.20E+3 uCi/gm dose equivalent Xe-133 and once per day when the specific activity is~ 2.20E+3 uCi/gm dose equivalent Xe-133. At Surry, waste gas is removed from the reactor coolant letdown by the Boron Recovery System. The gases are transferred to the Waste Gas Decay System without processing by the Catalytic Recombiners.

• The recombiners, used to strip hydrogen from primary gases, is not a functional system at Surry. Without the hydrogen removal system, hydrogen becomes the major component of the primary offgas. The remaining components of the offgas consist of nitrogen, oxygen and trace amounts of noble gases. The analysis of the Boron Recovery System by the Surry Environmental Applicants Report and the Update Final Safety Analysis Report, assume that 90-99% of the primary offgas is composed of hydrogen.

In an analysis to determine the maximum curie content in the Waste Gas Decay Tank (see Attachment

3) a conservative figure was used that assumes 10% of the primary offgas is composed of radioactive noble gases. The Waste Gas Decay Tank, which stores the primary offgases, is also assumed to contain a maximum of 10% by volume, radioactive noble gases. The curie limit in the Waste Gas Decay Tank is specified in Technical Specification 3.11.B.6 as 24,600 curies. To meet or exceed this curie limit, assuming 90% hydrogen and 10% noble gas content, the primary coolant activity, processed by the Boron Recovery System, would need to exceed 2278 uCi/ml (Xe-133 equivalent).

The specified primary coolant activity should remain at that level throughout the entire waste gas tank filling cycle. Station records show that none of the Waste Gas Decay Tanks releases since Surry's initial criticality, contained more than 2% of the curie content stated in specification 3.11.B.6.

Surveillance tied to the activity of the influent stream should provide a good indication as to when the activity in the tank is approaching specification limit. 16. Since there is no downstream drinking water supply, the default values have been used in Tables 4.9-4 and 4.9-5 wherever applicable.

17. Solid radioactive waste released from site is reported as outlined in Regulatory Guide 1.21 ,as stated in Specification 6.6.3.c. 18. In Table 4.9-5, Ba-La-140 is separated into Ba-140 and La-140 and Zr-Nb-95 is separated into Zr-95 and Nb-95 to comply with Radiological Assessment Branch Technical Position, Revision 1, November 1979. 19. Surry has an established environmental monitoring program and established methods so that the table notation for Table 4.9-3 is not necessary.

20. The Quality Assurance Program is not included in Specification 6.4.B.2 because a Station QA program, with written procedures exists at the station. Scheduled audits, quality control, and document control of the Health Physics. programs are addressed in the Nuclear Power Station Quality Assurance Manual. More specifically, the environmental program, which encompasses radiological and non-radiological controls, is audited on a scheduled basis with surveillance audits in the interim .

Introduction:

D. The Surry Power Station RETS submittal (reference

3) states: "The quantity of radioactivity contained in each gas storage tank shall be limited to less than or equal to 24,600 curies of noble gases (considered as Xel33)". To verify that justification considers the design volume, Approach:

the decay tanks do not exceed the above limit, a for the surveillance requirements is presented which physical limitations of the tanks design pressure and and the assumed composition of the primary offgases.

Reference 1 and 2 describe the Boron Recovery Systems stripping of primary gases from the reactor coolant. Also described in these references is the processing of the primary offgas to ensure that the hydrogen level in the offgas is maintained below the explosive mixture level. Within the description of this processing, assumptions were made that approximate the normal and maximum hydrogen concentration in the primary offgas. Assuming that this primary gas is transferred from the Boron Recovery System to an empty Waste Gas Decay Tank and the transfer of this gas continues until the tank is full, then a primary gas activity was determined that would give the total tank activity of 24,600 curies. No assumption of radiogas decay was taken into account. Assuming 100% efficiency of Boron Recovery System to strip primary gases, the activity determined above would be the action level, when reached in reactor coolant sampling, that would require a daily sampling of the Waste Gas Decay Tanks.
