Catawba Nuclear Station 2009 Radioactive Effluent Releases 40CFRI90 Uranium Fuel Cycle Dose Calculation Results In accordance with the requirements of 40CFRI90, the annual dose commitment to any member of the general public shall be calculated to assure that doses are limited to 25 millirems to the total body or any organ with the exception of the thyroid which is limited to 75 millirems. The fuel cycle dose assessment for Catawba Nuclear Station only includes liquid and gaseous effluent dose contributions from Catawba and direct and air-scatter dose from Catawba's Independent Spent Fuel Storage Installation (ISFSI) since no other uranium fuel cycle facility contributes significantly to Catawba's maximum exposed individual. The dose to a maximum exposed individual from Catawba's effluent releases is well below 40CFR190 limits as shown by the following summary:

I. 2009 Catawba 40CFRI90 Effluent Dose Summary The 40CFR190 effluent dose analysis to the maximum exposed individual from liquid and gas releases includes the dose from noble gases (i.e., total body and skin).

Maximum Total Body Dose = 1.615E+00 mrem Maximum Location: 0.5 Mile, Northeast Sector Critical Age: Child Gas non-NG Contribution: 95%

Gas NG Contribution: 2%

Liquid Contribution: 3%

Maximum Organ (other than TB) Dose = 1.596E+00 mrem Maximum Location: 0.5 Mile, Northeast Sector Critical Age: Child Critical Organ: Liver Gas Contribution: 97%

Liquid Contribution: 3%

II. 2009 Catawba 40CFR190 ISFSI Dose Summary Direct and air-scatter radiation dose contributions from the onsite Independent Spent Fuel Storage Installation (ISFSI) at Catawba have been calculated and documented in the "Catawba Nuclear Station, ISFSI, IOCFR72.212 Evaluation" report. The maximum dose rate to the nearest resident from the Catawba ISFSI is conservatively calculated to be 16.6 mrem/year.

The attached excerpt from the "Catawba Nuclear Station, ISFSI, I0CFR72.212' Evaluation" report is provided to document the method used to calculate the Catawba ISFSI 16.6 mrem/year dose estimate.

The effluent dose calculations consider radionuclides identified as part of the liquid and gaseous wastes sample and analysis program per SLC Table 16.11-1-1 and SLC Table 16.11-6-1.

The following three pages are taken from the "Catawba Nuclear Station, ISFSI, 10CFR72.212 Evaluation" report.

1CFR72.212 Evaluation NAC-UMS Universal Storage System CNSO Page 29 of 54 7.3 10CFR72.212(b)(2)(i)(C) - Requirements of §72.104

"(C) the requirementsof§72.104 have been met. A copy of this recordshall be retaineduntil spentfuel is no longer stored under the general license issued under §72.210."

The requirements of §72.104 are as follows:

(a) During normal operations and anticipated occurrences, the annual dose equivalent to any real individual who is located beyond the controlled area must not exceed 0.25 mSv (25 mrerm) to the whole body, 0.75 mSv (75 mrem) to the thyroid and 0.25 mSv (25 mrem) to any other critical organ as a result of exposure to:

(1) Planned discharges of radioactive materials, radon and its decay products excepted, to the general environment, (2) Direct radiation from ISFSI or MRS operations, and (3) Any other radiation from uranium fuel cycle operations within the region.

Doses from 24 loaded storage casks located at the ISFSI have been calculated. This represents the placement of a loaded canister at all available locations on the current ISFSI storage pad, completing the projected loading for Phase I.

CNS 10CFR72.212 Evaluation NAd-UMS Uhiversal St6ia& yste:m Page 30 of 54 The methodology and results of the dose calculations are discussed in detail in References 7.3-3 and 7.3-4. A summary of the methodology and results is presented below.

There are two calculations used to estimate the impact of the ISFSI direct radiation doses. The first calculation (Reference 7.3-3) determines a fuel assembly source term to be used in the subsequent shielding model. In order to bound fuel assemblies loaded into canisters in the past and projected to be loaded in the future, the same, bounding fuel assembly is modeled for all 24 spaces in each of the 24 casks. The source term was developed to bound all types of LEU fuel at Catawba (Westinghouse OFA, RFA, and Mk-BW). Axial flux profiles, fuel hardware activation, component activation, and the potential impacts from burnable poisons were modeled. Both gamma and neutron source spectrums were produced. In order to ensure that the gamma flux was conservative, the model includes the impact from activation of components, fuel hardware, and light elements. Thus, each spent fuel location models a bounding fuel assembly with a bounding activated component, (thimble plug).

The source term was modeled using the SAS2H coupled shielding and depletion analysis module of the SCALE code suite. This module utilizes the ORIGEN-S point depletion code to compute the source spectra. An appropriate 44 group library was employed. Use of this code is a standard industry application for source term depletion and decay calculations. It is utilized in a manner consistent with its development.

The results from the source term calculation (Reference 7.3-3) are used as the source term spectra input to the shielding model (Reference 7.3-4).

MCNP, a Monte-Carlo code for neutron and photon transport, was utilized for the shielding computations. This code is an industry standard and is typically applied to problems of this type. The fuel related source term was normalized to the 20 kW administrative decay heat limit and the component source term was normalized to an eight-year decay duration.

The MCNP models were set up using the source terms developed for the four source regions inReference 7.3-3: fuel (neutron and gamma), fuel hardware, upper plenum, and upper nozzle. These source regions include contributions from both the fuel assembly and the component, as physically appropriate.

The same mesh tally scheme was applied to each source case so the results for each source term could then be summed to produce the final result. A detailed cask model was developed (the work was performed by the cask vendor) and replicated in a 2 by 12 array mimicking the planned arrangement of the loaded canisters on the Catawba ISFSI pad. This represents a full pad of loaded canisters.

CNS 10CFR72.212 Evaluation NAC-UMS Universal Storage System Page 31 of 54 Detector locations were laid out on a grid in three dimensions and plots for both near and far field doses were obtained. However, because the coordinate axes align with the cask array orientation, the highest doses are seen along the axes. Thus, for a given distance the highest dose will be found along the x axis, as the long part of the array defines the y axis. The results are as expected for the near and far field doses. Conservatively, the coordinate system was eschewed in the evaluation of the results for 72.104 purposes in favor or the straight line distance to the limiting receptor location (nearest real individual). The nearest real individual is over 450 meters from the ISFSI, but a conservative evaluation distance of 405 meters is adopted. This distance from the ISFSI is within the site boundary. No real individual can live within the (site controlled) boundary, so this distance (location) bounds any real individual (living off-site). As shown in Table 6.7-5 of Reference 7.3-4, the annual dose to the nearest real individual from a full 2 by 12 array of loaded canisters with limiting 20 kW fuel sources and inserts decayed for eight years is 16.6 mrem/yr. The maximum dose at this distance is found, as expected, along

,the x axis. This is a conservative application of the shielding analysis results.

The shielding analysis contains many receptor locations, and the results from these cases could be used with a plot of the location of the nearest individual on the shielding model XY coordinates system. This would produce a more precise andlower result.

The computed direct shine dose from the ISFSI to the nearest individual will be added to the plant generated dose to show compliance with 72.104.

General Office Radiation Protection has responsibility for this function.

(b) Operational restrictions must be established to meet as low as is

reasonably achievable objectives for radioactive materials in effluents and direct radiation levels associated with ISFSI or MRS operations.

(c) Operational limits must be established for radioactive materials in effluents and direct radiation levels associated with ISFSI or MRS operations to meet the limits given in paragraph (a) of this section.

The requirements are met through implementation of the CNS Radiation Protection Program (References 7.3-1 and 7.3-2).

NOTES:

(1) The LLD is'defined, for purposes of these commitments, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5%

probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system, which may include radiochemical separation:

LLD =4.66 s b 6

E. V .2.22 x 10

Y" exp (-2At)

Where:,

LLD = the "a priori" lower limit of detection (microCurie 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 (counts per minute),

E = the counting efficiency (counts per disintegration),

V = the sample size (units of mass or volume),

2.22 x 106 = the number of disintegrations per minute per microCurie, Y = the fractional radiochemical yield, when applicable, X = the radioactive decay constant for the particular radionuclide (sec 1 ), and At = the elapsed time between midpoint of sample collection and time of counting (sec).

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

It should be recognized that 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.

(2) A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analyses, each batch shall be isolated, and then thoroughly mixed to assure representative sampling.

(3) The principal gamma emitters for which the LLD specification applies include the following radionuclides:

Catawba Units 1 and 2 16.11-1-3 Revision 0

Liquid Effluents 16.11-1 Table 16.11-1-1 Radioactive Liquid Waste Sampling and Analysis Program (page 3 of 3)

Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, and Ce-141. The LLD for Ce-144 is 5x10-6 jLCi/ml. This list does not mean that only these nuclides are to be considered. Other gamma peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Radioactive Effluent Release Report pursuant to Technical Specification 5.6.3 in the format outlined in Regulatory Guide 1.21, Appendix B, Revision 1, June 1974.

(4) A composite sample is one 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 that is representative of the liquids released.

(5) A continuous release is the discharge of liquid wastes of a non-discrete volume, e.g., from a volume of a system that has an input flow during the continuous release.

(6) To be representative of the quantities and concentrations of radioactive materials in liquid effluents, samples shall be collected continuously in proportion to the rate of flow of the effluent stream. Prior to analyses, all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be representative of the effluent release.

Liquid Effluents 16.11-1 BASES The basic requirements for SLCs concerning effluents from nuclear power reactors are stated in 10 CFR 50.36a. These requirements indicate that compliance with effluent SLCs will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 10 CFR 20.106 (new 10 CFR 20.1302). These requirements further indicate that operational flexibility is allowed, compatible with considerations of health and safety, which may temporarily result in releases higher than such small percentages, but still within the limits specified in the old 10 CFR 20.106 which references Appendix B, Table II concentrations (MPCs). These referenced concentrations are specific values which relate to an annual dose of 500 mrem. It is further indicated in 10 CFR 50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents as low as is reasonably achievable (ALARA) as set forth in 10 CFR 50, Appendix I.

As stated in the Introduction to Appendix B of the new 10 CFR 20, the liquid effluent concentration (EC) limits given in Appendix B, Table 2, Column 2, are based on an annual dose of 50 mrem. Since a release concentration corresponding to a limiting dose rate of 500 mrem/year has been acceptable as a SLC limit for liquid effluents, which applies at all times as an assurance that the limits of 10 CFR 50, Appendix I are not likely to be exceeded, it should not be necessary to reduce this limit by a factor of 10.

Operational history at Catawba has demonstrated that the use of the concentration values associated with the old 10 CFR 20.106 as SLC limits has resulted in calculated maximum individual doses to a MEMBER OF THE PUBLIC that are small percentages of the limits of 10 CFR 50, Appendix I.

Therefore, the use of concentration values which correspond to an annual dose of 500 mrem (ten times the concentration values stated in the new 10 CFR 20, Appendix B, Table 2, Column 2) should not have a negative impact on the ability to continue to operate within the limits of 10 CFR 50, Appendix I and 40 CFR 190.

Having sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the new 10 CFR 20, Appendix B, Table 2, Column 2, relate to a dose of 50 mrem in a year. When applied on an instantaneous basis, this corresponds to a dose rate of 50 mrem/year. This low value is impractical upon which to base effluent monitor setpoint calculations for many liquid effluent release situations when monitor background, monitor sensitivity, and monitor performance must be taken into account.

Therefore, to accommodate operational flexibility needed for effluent releases, the limits associated with SLC 16.11-1 are based on ten times the concentrations stated in the new 10 CFR 20, Appendix B, Table 2, Column 2, to apply at all times. The multiplier of ten is proposed because the annual dose of 500 mrem, upon which the concentrations in the old 10 CFR 20, Appendix B, Table II, Column 2, are based, is a factor of 10 higher than annual dose of 50 mrem, upon which the concentrations in the new 10 CFR Catawba Units 1 and 2 16.11-1-5 Revision 0

Liquid Effluents 16.11-1 BASES (continued) 20, Appendix B, Table 2, Column 2, are based. Compliance with the limits of the new 10 CFR 20.1301 will be demonstrated by operating within the limits of 10 CFR 50, Appendix I and 40 CFR 190. 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)

Dose

.16.11-3 TESTING REQUIREMENTS TEST FREQUENCY TR 16.11-3-1 Determine cumulative dose contributions from liquid 31 days effluents for current calendar quarter and current calendar year in accordance with the methodology and parameters in the ODCM.

BASES This SLC is provided to implement the requirements of Sections II.A, III.A and IV.A of Appendix 1,10 CFR Part 50. The COMMITMENT implements the guides set forth in Section II.A of Appendix I. The REMEDIAL 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 is reasonably achievable". Also, for fresh water sites with drinking water supplies that can be potentially affected by plant operations, there-is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR Part 141. The dose calculation methodology and parameters 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 a 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 liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 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 SLC applies to the release of radioactive materials in liquid effluents from each unit at the site. When shared radwaste treatment systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the radwaste treatment system. For determining conformance to COMMITMENTS, these allocations from shared radwaste treatment systems are to be added to the releases specifically attributed to each unit to obtain the total releases per unit.

BASES The FUNCTIONALITY of the Liquid Radwaste Treatment System ensures that this system will be available for use whenever liquid effluents require treatment prior to release to the environment. 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 COMMITMENT 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 1, 10 CFR Part 50, for liquid effluents.

This SLC applies to the release of radioactive materials in liquid effluents from each unit at the site. When shared radwaste treatment systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit.

BASES The inventory limits of the CTPs are based on limiting the consequences of an uncontrolled release of the pond inventory.

The filter/demineralizers using powdered resin and the blowdown demineralizer are backwashed or sluiced to a holding tank. The tank will be agitated to obtain a representative sample of the resin inventory in the tank. A known weight of the wet, drained resin (moisture content approximately 55 to 60%, bulk density of about 58 pounds per cubic foot) will then be counted. The concentration of the resin slurry to be pumped to the CTPs will then be determined by the formula:

(2) The principal gamma emitters for which the LLD specification applies include the following radionuclides: Kr-87, Kr-88, Xe-1 33, Xe-1 33m, Xe-1 35, and Xe-1 38 in noble gas releases based on grab samples and Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, 1-131, Cs-134, Cs-137, and Ce-141 in Iodine and particulate releases based on continuous samples. The LLD for Ce-144 is 5x10-9 pRCi/ml and is based on continuous samples. This list does not mean that only these nuclides are to be considered. Other gamma peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Radioactive Effluent Release Report, pursuant to Technical Specification 5.6.3 in the format outlined in Regulatory Guide 1.21, Appendix B, Revision 1, June 1974.

(3) Sampling and analysis shall also be performed following shutdown, startup, or a THERMAL POWER stabilization (power level constant at desired power level) after a THERMAL POWER change exceeding 15% of RATED THERMAL POWER within a 1-hour period, for at least one of the three gaseous release types with this notation.

(4) Tritium grab samples shall be taken at least once per 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months when the refueling canal is flooded.

(5) Required sampling and analysis frequency during effluent release via this pathway.

If the particulate and charcoal sample frequency is changed to a 24-hour frequency, the corresponding LLDs may be increased by a factor of 10 (e.g., LLD for 1-131 from lxi 012 to lxi 0-11 RCi/ml).

Catawba Units 1 and 2 16.11-6-5 Revision 1

Gaseous Effluents 16.11-6 BASES The basic requirements for SLCs concerning effluents from nuclear power reactors are stated in 10 CFR 50.36a. These requirements indicate that compliance with effluent SLCs will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 10 CFR 20.106 (new 10 CFR 20.1301). These requirements further indicate that operational flexibility is allowed, compatible with considerations of health and safety, which may temporarily result in releases higher than such small percentages, but still within the limits specified in the old 10 CFR 20.106 which references Appendix B, Table II concentrations (MPCs). These referenced concentrations are specific values which relate to an annual dose of 500 mrems. It is further indicated in 10 CFR 50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents as low as is reasonably achievable (ALARA) as set forth in 10 CFR 50, Appendix I.

As stated in the Introduction to Appendix B of the new 10 CFR 20, the gaseous effluent concentration (EC) limits given in Appendix B, Table 2, Column 1, are based on an annual dose of 50 mrems for isotopes for which inhalation or ingestion is limiting or 100 mrems for isotopes for which submersion (noble gases) is limiting. Since release concentrations corresponding to limiting dose rates less than or equal to 500 mrems/year to the whole body, 3000 mrems/year to the skin from noble gases, and 1500 mrems/year to any organ from Iodine-1 31, Iodine-1 33, tritium, and all radionuclides in particulate form with half-lives greater than 8 days at the site boundary has been acceptable as a SLC limit for gaseous effluents to assure that the limits of 10 CFR 50, Appendix I and 40 CFR 190 are not likely to be exceeded, it should not be necessary to restrict the operational flexibility by incorporating the dose rate associated with the EC value for isotopes based on inhalation/ingestion (50 mrems/year) or the dose rate associated with the EC value for isotopes based on submersion (100 mrems/year).

Having sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the new 10 CFR 20, Appendix B, Table 2, Column 1, relate to a dose of 50 or 100 mrems in a year. When applied on an instantaneous basis, this corresponds to a dose rate of 50 or 100 mrems/year.

These low values are impractical upon which to base effluent monitor setpoint calculations for many gaseous effluent release situations when monitor background, monitor sensitivity, and monitor performance must be taken into account.

Therefore, to accommodate operational flexibility needed for effluent releases, the limits associated with gaseous release rate SLCs will be maintained at the current instantaneous dose rate limit for noble gases of 500 mrems/year to the whole body and 3000 mrems/year to the skin; and for Iodine-1 31, for Iodine-1 33, for tritium, and for all radionuclides in particulate Catawba Units 1 and 2 16.11-6-6 Revision 1

Gaseous Effluents 16.11-6 BASES (continued) form with half-lives greater than 8 days, an instantaneous dose rate limit of 1500 mrems/year to any organ.

Compliance with the limits of the new 10 CFR 20.1301 will be demonstrated by operating within the limits of 10 CFR 50, Appendix I and 40 CFR 190.

Operational history at Catawba has demonstrated that the use of the dose rate values listed above (i.e., 500 mrems/year, 3000 mrems/year, and 1500 mrems/year) as SLC limits has resulted in calculated maximum individual doses to MEMBERS OF THE PUBLIC that are small percentages of the limits of 10 CFR 50, Appendix I and 40 CFR 190.

The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrem/year to the whole body and to less than or equal to 3000 mrem/year to the skin from noble gases, and to less than or equal to 1500 mrem/year to any organ from Iodine-131, Iodine-1 33, tritium, and all radionuclides in particulate form with half-lives greater than eight days.

This commitment applies to the release of radioactive materials in gaseous effluents from all units at the site.

The required detection capabilities for radioactive material in gaseous waste samples are tabulated in terms of the lower limits of detection (LLDs). Based on NUREG-1301 and Regulatory Guide 1.21, the LLD value of lx10-4 g Ci/ml for grab samples is only applicable to noble gases grab samples and the LLD values for particulate and iodine radionuclides are applicable to continuous charcoal and particulate samples. The Table 16.11-6-1 Gaseous Release Type Number 6 (Waste Monitor Tank Building Ventilation Exhaust) LLDs are based on weekly samples per NUREG-1301. The Table 16.11-6-1 Gaseous Release Type Number 5 (All Release Types as Listed in 3. Above) LLDs, for the 24-hour charcoal and particulate samples, are based on daily (once per 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months ) samples per NUREG-1301. There are two isotopes with associated LLDs that do not agree directly with NUREG-1301: Ce-144, LLD of 5x10-9

ýiCi/ml, which has historically been applied and achieved for analytical results, and 1-133, LLD of lx10Q10 pCi/ml, which again has been historically listed, as 1x10-9 [tCi/ml, for Radioactive Gaseous Waste Sampling but changed to be in agreement with 1-131 for weekly (7-day) samples and is not specified in NUREG-1301. Detailed discussion of the LLD, and other detection limits can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, J.K., "Detection Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

Dose - Noble Gases 16.11-8 BASES This SLC is provided to implement the requirements of Sections II.B, III.A and IV.A of Appendix 1,10 CFR Part 50. The COMMITMENT implements the guides set forth in Section 11.B of Appendix I. The REMEDIAL ACTION statement provides 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 to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable". The TESTING REQUIREMENTS 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 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 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. The ODCM equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

This commitment applies to the release of radioactive materials in gaseous effluents from each unit at the site. When shared radwaste treatment systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactives waste producing units sharing the radwaste treatment system. For determining conformance to COMMITMENTS, these allocations from shared radwaste treatment systems are to be added to the releases specifically attributed to each unit to obtain the total releases per unit.

Dose - Iodine-1 31, Iodine-1 33, Tritium, and Radioactive Material in Particulate Form 16.11-9 BASES This SLC is provided to implement the requirements of Sections II.C, III.A and IV.A of Appendix 1, 10 CFR Part 50, and are the guides set forth in Section II.C of Appendix I. The REMEDIALACTION 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 to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable". The ODCM calculational methods specified in the TESTING REQUIREMENTS 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 a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated. The ODCM calculational methodology and parameters 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, COMMITMENTS for Iodine-131, Iodine-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 and beyond the SITE BOUNDARY. The pathways that were examined in the 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 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.

This commitment applies to the release of radioactive materials in gaseous effluents from each unit at the site. When shared radwaste treatment systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent releases may be allocated equally to each of the radioactive waste producing units sharing the radwaste treatment system.

BASES The FUNCTIONALITY of the WASTE GAS HOLDUP SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM ensures that the systems will be available for use whenever gaseous effluents require treatment prior to release to the environment. 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 COMMITMENT implements the requirements of 10 CFR 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 governing the use of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Sections 11.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

This SLC applies to the release of radioactive materials in gaseous effluents from each unit at the site. When shared radwaste treatment systems are used by more than one unit on a site, the wastes from all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately be ascribed to a specific unit.

Cumulative dose contributions from liquid and gaseous effluents shall be determined in accordance with SLC 16.11-3, SLC 16.11-8, and SLC 16.11-9, and in accordance with the methodology and parameters specified in the ODCM.,

TEST FREQUENCY TR 16.11-12-1 Determine cumulative dose contributions from direct When calculated radiation from the units and from radwaste storage tanks doses from in accordance with the methodology and parameters effluent releases specified in the ODCM. exceed twice the limits of SLC 16.11-3, SLC 16.11-8, or SLC 16.11-9 BASES This SLC is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 10 CFR Part 20 by 46 FR 18525. The SLC 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 mrem to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem.

For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiation doses from the units and from outside storage tanks are kept small.

This Special Report, as defined in 10 CFR 20.2203(a)(4), 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 release(s) 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. 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 Part 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.

Total Dose 16.11-12 BASES (continued)

If the dose to any 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 190.11 and 10 CFR 20.2203(a)(4), is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 and a variance is granted 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 SLC 16.11-1 and SLC 16.11-6.

(1) Specific parameters of distance and direction sector from the centerline of the station, and additional description where pertinent, shall be provided for each and every sample location in Table 16.11-13-1 in a table and figure(s) in-the ODCM.

Refer to NUREG-01 33, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants," October 1978, and to Radiological Assessment Branch Technical Position, 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, and malfunction of automatic sampling equipment. If specimens are unobtainable 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 Annual Radiological Environmental Operating Report pursuant to Technical Specification 5.6.2. 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. In lieu of any Licensee Event Report required by 10 CFR 50.73 and pursuant to Technical Specification 5.6.3, identify the cause of the unavailability of samples for that pathway and identify the new location(s) for obtaining replacement samples in the next Radioactive Effluent Release Report and also include in the report a revised figure(s) and table for the ODCM reflecting the new location(s).

(2) 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 thermoluminescent dosimeter (TLD) is considered to be one phosphor; two or more phosphors in a packet are considered as two or more dosimeters. Film badges shall not be used as dosimeters for measuring direct radiation. (The 40 stations is not an absolute number. The number of direct radiation monitoring stations may be reduced according to geographical limitations; e.g., at an ocean site, some sectors will be over water so that the number of dosimeters may be reduced accordingly. The frequency of analysis or readout for TLD systems will depend upon the characteristics of the specific system used and should be selected to obtain optimum dose information within minimal fading.)

(3) Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or more after sampling to allow for radon and thoron daughter decay.

NOTES:

(1) This list does not mean that only these nuclides are to be considered. Other peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radiological Environmental Operating Report pursuant to Technical Specification 5.6.2.

(2) Required detection capabilities for thermoluminescent dosimeters used for environmental measurements shall be in accordance with the recommendations of Regulatory Guide 4.13.

(3) The LLD is defined, for purposes of these commitments, as the smallest concentrations of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5%

probability of falsely concluding that a blank observation represents a "real" signal.

For a particular measurement system, which may include radiochemical separation:

LLD 4.66s h E. V.2.22- Y -exp (- A A t)

Where:

LLD = the "a priori" lower limit of detection (picoCuries 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 (counts per minute);

E = the counting efficiency (counts per disintegration);

V = the sample size (units of mass or volume);

2.22 = the number of disintegrations per minute per picoCurie; Y = the fractional radiochemical yield, when applicable; X = the radioactive decay constant for the particular radionuclide (sec-1 ); and At = the elapsed time between environmental collection, or end of the sample collection period, and time of counting (sec).

Typical values of E, V, Y and qt shall be used in the calculation.

Monitoring Program 16.11-13 BASES The Radiological Environmental Monitoring Program required by this SLC 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 of MEMBERS OF THE PUBLIC resulting from the plant 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. Guidance for this Monitoring Program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring. The initially specified Monitoring Program will be effective for at least the first 3 years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs). The LLDs required by Table 16.11-13-3 are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

With the level of radioactivity in an environmental sampling medium at a specified location exceeding the reporting levels of Table 16.11-13-2 when averaged over any calendar quarter, in lieu of a Licensee Event Report, prepare and submit to the Commission within 30 days a Special Report that 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 SLC 16.11-3, SLC 16.11-8, and SLC 16.11-9.

When more than one of the radionuclides in Table 16.11-13-2 are detected in the sampling medium, this report shall be submitted if:

concentration (1) concentration (2) +... >1.0 reporting level (1) reporting level (2)

When radionuclides other than those in Table 16.11-13-2 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 equal to or greater than the calendar year limits of SLC 16.11-3, SLC 16.11-8, and SLC 16.11-9. 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 required by Technical Specification 5.6.2. The methodology and parameters used to estimate the potential annual dose to a MEMBER OF THE PUBLIC shall be indicated in the 30-day Special Report.

Conduct a Land Use Census during the growing season 12 months using the information which will provide the best results such as a door-to-door survey, aerial survey, or consultation with local agricultural authorities.

BASES This SLC 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 given in the ODCM are made if required by the results of this census. The best information from the door-to-door survey, from aerial survey, or from consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 50 m2 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantify (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and (2) a vegetation yield of 2 kg/M 2.

Groundwater Protection Initiative

ARERR Groundwater Well Data Section Duke Energy implemented a Ground Water Protection program in 2007. This initiative was developed to ensure timely and effective management of situations involving inadvertent releases of licensed material to ground water. As part of this program, Catawba has forty-six ground water monitoring wells in place. These wells are currently sampled quarterly (with the exception of the five LMW wells which are sampled semi-annually). All samples are being analyzed for tritium and gamma emitters. No gamma activity (other than naturally occurring radionuclides) was identified in any of the well samples during 2009.

Results from sampling during 2009 identified ground water contamination at location C-213. This contamination was identified as coming from backflow from the Monitor Tank Building (MTB) truck bay sump into the WL trench entering the MTB from the east side. Additional wells were installed near C-213 to identify the extent of the contamination.- The contamination and resulting investigation activities were reported to the NRC and to state and local officials. Monitoring of this area is on-going.

Results from sampling during 2009 are shown in the table below.

ATTACHMENT X Inoperable Equipment

EMF-39 and 36 non-functional for 21 hours2.430556e-4 days 0.00583 hours 3.472222e-5 weeks 7.9905e-6 months during which 3 Gaseous Waste Releases were made' EMF-39 is the Containment (Gas) Airborne Monitor; it provides alarm and automatic termination of releases. When a unit is in Mode 1, as Unit 2 was in on February 8th and 9th, the EMF is required to meet Select Licensee Commitment (SLC) 16.11-7, Condition J. This condition further specifies that EMF 36 (Unit Vent (Gas) Airborne Monitor) be verified as functional prior to initiating a release with EMF-39 non-functional.

On February 8, 2010 at approximately 10:00 am, the 2EMF-38 sample filter paper was changed out.

Then on February 9, it was identified that 2EMF-39 counts had decreased from approximately 400 counts per minute (cpm) to 150 cpm following the 2EMF-38 filter paper change the previous day. The EMF flow rate was then observed locally at the monitor and the EMF sample chamber T- handle was tightened to eliminate any potential sample chamber in-leakage from the auxiliary building. The EMF at approximately 0755 was discovered to have a flow rate of 4.31 square cubic feet perminute (SCFM).

The T-handle on the sample holder was tightened about another Y2 turn and the flow rate decreased to 3.71 SCFM. The 2EMF-39 returned to functional as the count rate returned to 400 cpm. The EMF's sample was diluted with auxiliary building air from 10:00 am on February 8th through 08:15 am on February 9th, meaning 2EMF39 was non-functional for a period of approximately 22.25 hours2.893519e-4 days 0.00694 hours 4.133598e-5 weeks 9.5125e-6 months . This issue was entered into the station's corrective action program as PIP C-10-00779.

During periods when 2EMF39 is non-functional, reliance is upon 2EMF-36 for performing radioactive releases. PIP C-10-00781 was generated identifying that 2EMF-36 suffered from the same in-leakage condition as 2EMF-39 rendering it non-functional from approximately 1100 on 2-8-1010 to 1650 on 2 2010. A review of station logs indicated that Gaseous Waste Release (GWR) 2010-014 was performed on 02/08/2010 and 02/09/2010 at the following times when both 2EMF39and 2EMF36 were non-functional:

Start 11:45 End 13:46 2/8/2010 Start 20:19 End 22:18 2/8/2010 Start 04:42 End 07:25 2/9/2010 The RP procedure for replacing the filter sample holder after filter change out states: "Rotate handle on front end of shield CW (clockwise) until noticeable resistance is felt". There is also a caution associated with the step stating "CAUTION: Over tightening handle will cause excess wear to "0" rings and possibly damage the detector". This subjective direction had led to the under-tightening of the handles which rendered both EMFS non-functional. '

Interim actions are for Radiation Protection (RP) personnel to "smoke-test" the monitor following filter paper replacements in order to identify in-leakage. Long-term actions are to install vacuum gages on these monitors which will provide indication of properly seated o-rings. These items have been entered into the corrective action program (PIP).

OEMF50 - Waste Gas Discharge Monitor The Waste Gas Discharge monitor is a dual range monitor that monitors the gaseous beta activity released to the environment from Waste Gas (WG) System Decay Tank C. The waste gas decay tanks contain radioactive noble gases that, after laboratory analysis, may be released through the Unit 1 unit vent on a controlled basis.

On 28 April 2009 three high-radiation trips occurred on 0EMF50 at the start of Gaseous Waste Release (GWR) 2009-030. Problem Investigation Process (PIP) C-09-02848 was initiated in response to these trips. The monitor was entered into TSAIL (C0-09-00981). The apparent cause of the higher than expected response is the presence of Carbon-14 (C14) in the Waste Gas stream.

Since 0EMF50 operates using a beta-scintillation detector, it is sensitive to both gamma and beta emitting isotopes. The Count Room is not equipped for the detection of beta-emitting isotopes (see discussion of the Radioactive Gaseous Waste Sampling and Analysis Program, below). Thus the Count Room correlates the response of the radiation monitor using only the gamma isotopes and does not account for the presence of C14 a pure beta-emitting isotope.

The Radioactive Gaseous Waste Sampling and Analysis Program (reference SLC Table 16.11-6-1) identifies that for the Waste Gas Storage Tank, the principal gamma emitters is the type of activity analyzed. The principal gamma emitters are defined as the following radionuclides: Kr-87; Kr-88; Xe-133; Xe-133m; Xe-135 and Xe-138. Other gamma peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Radioactive Effluent Release Report.

Since C14 does not require reporting the approach will be to raise the lower discriminator setting of the Waste Gas Discharge Monitor (OEMF50) to eliminate the contribution of C14 to the overall count rate.

Performing this will alter the response of the monitor to the concentration of gamma isotopes.

Therefore a primary calibration must be performed in order to correlate the response of the monitor to gamma isotopes at the higher discriminator setting.

Engineering is presently pursuing the performance of a primary calibration with the vendor (open corrective action in PIP C-09-02848). Once the new calibration report is received, the applicable procedures, design documents, and UFSAR changes can be made. These changes will include a new correlation factor (cpm/(uCi/ml)) that will not be impacted by the presence of C14.

TSAIL entry CO-09-00981 was exited on 12/29/2009 even though the effects of C14 had not been addressed. The position taken was that the monitor was responding in a conservative manner (count rate was higher than what was being estimated).

Subsequently three high-radiation trips of OEMF50 occurred on GWR 2010-006. The monitor will remain in TSAIL until such time as the primary calibration has been completed and the respective plant documentation has been updated with the results.

OEMF57 - Waste Monitor Tank Building Liquid Discharge Monitor The Waste Monitor Tank Building (WMTB) Liquid Discharge monitor is equipped with a dual range gamma liquid detector assembly. This assembly monitors the Liquid Waste (WL) system discharge from the WMTB to the Low-Pressure Service Water discharge. Levels exceeding the high radiation setpoint will terminate the WL release by closing the discharge isolation valve, and will activate high radiation annunciators in the WMTB and the Auxiliary Building.

On 14 September 2009 OEMF57 was entered into TSAIL (CO-09-02130) in order to perform routine maintenance (WO 01882197; Perform ACOT on OEMFOO57). This work was bundled with a channel calibration (WO 01884540). The As-Found response of the detector to the calibration sources was low.

Degraded components were identified and replaced. The monitor was returned to service on 08 October 2009.

On 04 December 2009 Radiation Protection (RP) personnel identified that 0EMF57 over responded during Liquid Waste Release (LWR) 2009-078. Work Request 00995396 and Problem Investigation Process (PIP) C-09-07441 were initiated. TSAIL entry CO-09-02763 was made in response to the Work Request.

The Work Request identified foreign material in the system (high count rates during release are caused by solids in the liquid waste system). Calibration performed on the monitor determined that it was responding appropriately to the calibration sources. PIP C-09-07441 drove out the investigation of the solids being present in the radiation monitor, but not being accounted for in the Chemistry sample.

This investigation determined that Sodium Hydroxide (NaOH) had been added to a Waste Monitor Tank in the past. This resulted in material precipitation out of solution. When the tank was recirculated and sampled, the precipitate did not appear in the sample because the size of the material was larger than the restrictions in the sample line. The material collected in the chamber of the radiation monitor resulting in a higher than expected response during the release.

The TSAIL entry was cleared on 06 January 2010 once it was determined that the radiation monitor (OEMF57) was responding appropriately.

Unit 1 Unit Vent Continuous Sampler Out of Service for Approximately 10 Hours The Unit Vent Continuous Sampler draws a sample from the Unit Vent in conjunction with the Unit Vent Radiation Monitors. The Sampler is required to be functional at all times per Selected Licensee Commitment (SLC) Table 16.11-7-1.

On November 27, 2009 at approximately 10:54 am, the Unit Vent Continuous Sample pump was discovered not operating due to a loss of power. This pump provides sampling capability as required by SLC Table 16.11-7-1 for particulate and iodine releases via the Unit Vent.

The loss of power was due to the receptacle providing power to this pump being part of an electrical tag-out that had taken place around 0350 the morning of November 27. The pump was last verified operating when sampling was performed at 0103 on November 27.

Pump was plugged into an operational outlet and continuous sampling was resumed. The maximum time that the pump was not operating is 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months 51 minutes.
