Nuclear weapons testing in the 1950s and 1960s significantly increased the amount ofC-14 in the atmosphere.
C-14 is also produced in commercial nuclear reactors, but the amounts produced are much less than those produced naturally or from weapons testing. In Regulatory Guide 1.21, Revision 2, "Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste", the NRC recommends U.S. nuclear power plants evaluate whether C-14 is a "principal radionuclide", and if so, report the amount of C-14 released.
At McGuire, improvements over the years in effluent management practices and fuel performance have resulted in a decrease in gaseous radionuclide (non-C-14) concentrations, and a change in the distribution of gaseous radionuclides released to the environment.
As a result, C-14 has become a "principal radionuclide" for the gaseous effluent pathway at McGuire, as defined in Regulatory Guide 1.21, Rev. 2. McGuire's 2014 Annual Radioactive Effluent Release Report (ARERR) contains estimates of C-14 radioactivity released in 2014, and estimates of public dose resulting from the C-14 effluent.
Because the dose contribution of C-14 from liquid radioactive waste is much less than that contributed by gaseous radioactive waste, evaluation of C-14 in liquid radioactive waste at McGuire is not required (Ref. Reg. Guide 1.21, Rev. 2). The quantity of gaseous C-14 released to the environment can be estimated by use ofa C-14 source term scaling factor based on power generation (Ref. Reg. Guide 1.21, Rev. 2). Many documents provide information related to the magnitude of C-14 in typical effluents from commercial nuclear power plants. Those documents suggest that nominal annual releases of C-14 in gaseous effluents are approximately 5 to 7.3 curies from PWRs (Ref. Reg. Guide 1.21, Rev. 2). A more recent study recommends a higher C-14 gaseous source term scaling factor of approximately 9.0 to 9.8 Ci/GWe-yr for a PWR (Westinghouse) (Ref. EPRI 1021106).
For the 2014 McGuire ARERR a source term scaling factor of 9.4 Ci/GWe-yr is assumed. Using a source term scaling factor of 9.4 Ci/GWe-yr and actual electric generation (MWe-hrs) from McGuire in 2014 results in a site total C-14 gaseous release estimate to the environment of -20 Curies. 70% of the C-14 gaseous effluent is assumed to be from batch releases (e.g. WGDTs), and 30% of C-14 gaseous effluent is assumed to be from continuous releases through the unit vents (ref. IAEA Technical Reports Series no. 421, "Management of Waste Containing Tritium and Carbon-14", 2004). C-14 releases in PWRs occur primarily as a mix of organic carbon and carbon dioxide released from the waste gas system. Since the PWR operates with a reducing chemistry, most, if not all, of the C-14 species initially produced are organic (e.g., methane).
As a general rule, C-14 in the primary coolant is essentially all organic with a large fraction as a gaseous species. Any time the RCS liquid or gas is exposed to an oxidizing environment (e.g. during shutdown or refueling), a slow transformation from an organic to an inorganic chemical form can occur. Various studies documenting measured C-14 releases from PWRs suggest a range of70% to 95% organic with an average of 80% organic with the remainder being C0 2 (Ref. EPRI TR-105715).
For the McGuire 2014 ARERR a value of 80% organic C-14 is assumed. Public dose estimates from airborne C-14 are performed using dose models in NUREG-0133 and Regulatory Guide 1.109. The dose models and assumptions used are documented in the McGuire ODCM. The estimated C-14 dose impact on the maximum organ dose from airborne effluents released from McGuire in 2014 is well below the IOCFR50, Appendix I, ALARA design objective (i.e., 15 mrem/yr per unit).

The fuel cycle dose assessment for McGuire Nuclear Station only includes liquid and gaseous effluent dose contributions from McGuire and direct and air-scatter dose from McGuire's onsite Independent Spent Fuel Storage Installation (ISFSI) since no other uranium fuel cycle facility contributes significantly to McGuire's maximum exposed individual.
Included in the gaseous effluent dose calculations is an estimate of the dose contributed by Carbon-14 (Ref. "Carbon-14 Supplemental Information", contained in the ARERR for further information).
The combined dose to a maximum exposed individual from McGuire's effluent releases and direct and scatter dose from McGuire's ISFSI is below 40CFR190 limits as shown by the following summary: I. 2014 McGuire 40CFR190 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).

The maximum dose rate to the nearest real individual from the McGuire ISFSI is conservatively calculated to be less than 4 mrem/yr. The attached excerpt from the "McGuire Nuclear Station 10 CFR 72.212 Evaluation Report" is provided to document the method used to calculate the McGuire ISFSI less than 4 mrem/year dose estimate to the nearest real individual.
6.0 I 0 CFR 72.212(b)(5)(iii)
Radioactive Materials in Effluents and Direct Radiation
6.1 Purpose
I 0 CFR 72.212(b)(5)(iii) requires the general licensee to perform written evaluations, before use and before applying the changes authorized by an amended CoC to a cask loaded under the initial CoC or an earlier amended CoC, that establish that the requirements of l 0 CFR 72. l 04 have been met. A copy of this record shall be retained until spent fuel is no longer stored under the general license issued under I 0 CFR 72.210. l 0 CFR 72.104 provides the regulatory criteria for radioactive materials in effluents and direct radiation from an independent spent fuel storage installation (ISFSl) during normal operation and anticipated occurrences.
Specifically, I 0 CFR 72.104(a) limits the annual dose equivalent to any real individual who is located beyond the controlled area to 25 mrem to the whole body, 75 mrem to the thyroid, and 25 mrem to any other critical organ. This dose equivalent must include contributions from (l) planned discharges of radioactive materials (radon and its decay products excepted) to the general environment, (2) direct radiation from ISFSI operations, and (3) any other radiation from uranium fuel cycle operations within the region. In addition, I 0 CFR 72. I04(b) requires that operational restrictions be established to meet as low as is reasonably achievable (ALARA) objectives for radioactive materials in effluents and direct radiation levels associated with ISFSI operations.
Also, 10 CFR 72.104(c) requires that operational limits be established for radioactive materials in effluents and direct radiation levels associated with ISFSI operations to meet the mentioned dose limits. This section provides the written evaluation required by I 0 CFR 72.212(b )( 5)(i ii), demonstrating Duke Energy's comp I iance with the requirements of I 0 CFR 72.104 for the MNS ISFSI. 6.2 Evaluation This evaluation addresses the radiological dose rate from a composite population of all MNS lSFSl cask types. 6.2.1 §72.104(a)-Dose Limits Duke Energy Engineering Instruction MCEI-0400-241 determined that the distance from the nearest residence to the ISFSI is 0.65 miles (1046 meters). Hence, it is conservative to assume that the closest real individual is at least 700 meters from the ISFSJ. Enercon determined the annual total dose (gamma plus neutron) at a distance of 700 meters from all currently loaded casks (lO 1N-32A casks and 28 NAC-UM<;
casks) to be approximately 1.62 mrem. The evaluation was based on actual cask average burn-up (as loaded) and considering cooling time on the storage pads as of September 1, 2010. The distance at which this dose is calculated (700 meters) is conservative compared to the distance to the closest real individual.
NAC International determined the annual total dose (gamma plus neutron) at a distance of 700 meters from a (future) 2x6 array of MAGNASTOR casks to be approximately 1.01 mrem (2.02 mrem for two arrays). The evaluation was conservatively based on full cask loads of 37 fuel assemblies at the maximum allowable heat load of 35.5 kW. The distance at which this dose is calculated (700 meters) is conservative compared to the distance to the closest real individual.
The total calculated annual public dose from liquid and gaseous effiuent pathways averaged over a ten-year period is less than l mrem. No other uranium fuel cycle facility contributes significantly to the dose received by the closest real individual.
Based on the above, the calculated annual dose to the closest real individual due to the ISFSI, which is comprised of the currently existing ten TN-32A casks and 28 NAC-UMS casks, and up to two 2x6 arrays of MAGNASTOR casks (see Note below), is detennined to be less than 4 mrem, and the estimated annual dose due to McGuire power generation is less than l mrem. Hence, the total annual dose to the closest real individual (less than 5 mrem) is within the 10 CFR 72. l 04(a) limit. Note: As stated above, up to two 2x6 arrays of MAGNASTOR casks are assumed in this evaluation.
The first eight MAGNASTOR casks are planned to be placed on a concrete pad currently containing four NAC-UMS casks. This will conservatively count as one 2x6 array. Additional MAGNASTOR casks will be placed on their own concrete pad (the second 2x6 array). Hence, this §72. l 04(a) evaluation bounds up to 20 MAGNASTOR casks, arranged as described.

-Concentration 16.11.1 NOTES: TABLE 16.11.1-1 (Page 2 of 3) (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= (2.71/T)+4.65Sb E
- V
- 2.22 x 10 6
- Y
- exp (-Mt) Where: LLD is the "a priori" lower limit of detection as defined above (as microCurie 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), E is the counting efficiency (as counts per disintegration), Vis the sample size (in units of mass or volume), 2.22 x 10 6 is the number of disintegrations per minute per microCurie, Y is the fractional radiochemical yield (when applicable), /... is the radioactive decay constant for the particular radionuclide, is the elapsed time between midpoint of sample collection and time of counting (for plant effluents, not environmental samples), and T is the background and sample counting time in minutes. Typical values of E, V, Y and 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 posteriori (after the fact) limit for a particular measurement.
(2) 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 which is representative of the liquids released.
McGuire Units 1 and 2 16.11.1-3 Revision 137 TABLE 16.11.1-1 (Page 3 of 3) Liquid Effluents
-Concentration 16.11.1 (3) To be representative of the quantities and concentrations of radioactive materials in liquid effluents, samples shall be collected continuously or intermittently 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. (4) A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analyses, each batch shall be isolated and thoroughly mixed to assure representative sampling.
(5) A continuous release is the discharge of liquid wastes of a nondiscrete volume; e.g., from a volume of system that has an input flow during the continuous release. (6) The 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, and Ce-141. The LLD for Ce-144 is 5x1 microCi/ml.
This list does not mean that only these nuclides are to be detected and reported.
Other peaks which are measurable and identifiable, together with the above nuclides, shall be identified and reported in the Annual Radioactive Effluent Release Report. (7) The principal gas gamma emitters for which the LLD specification applies are Xe-133 and Xe-135. These are the reference nuclides in Regulatory Guide 1.21.

-Concentration 16.11.1 This commitment is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than 10 times the effluent concentration levels specified in 10 CFR Part 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 Part 50, to a MEMBER OF THE PUBLIC, and (2) the limits of 10 CFR Part 20.1301 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 EC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication
- 2. This commitment applies to the release of liquid effluents from all reactors at the site. The basic requirements for the Selected Licensee Commitments concerning effluents from nuclear power reactors are stated in 10CFR50.36a.
These requirements indicate that compliance with effluent Selected Licensee Commitments will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 1OCFR20.106 (new 1 OCFR20.1301
). 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 1OCFR20.106 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 1 OCFR50.36a 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 10CFR50, Appendix I. As stated in the Introduction to Appendix B of the new 10CFR20, the 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 1 OCFR50, 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/McGuire/Oconee has demonstrated that the use of the concentration values associated with the old 1OCFR20.106 as SLC limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the limits of 10CFR50, Appendix I. Therefore, the use of concentration values which correspond to an annual dose of 500 mrem should not have a negative impact on the ability to continue to operate within the limits of 10CFR50 Appendix I and 40CFR190.
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 10CFR20, 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. BASES (continued)
McGuire Units 1 and 2 16.11.1-6 Revision 137 Liquid Effluents
-Concentration 16.11.1 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 1 OCFR20, Appendix 8, 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 10CFR20, Appendix 8, Table II, Column 2 are based, is a factor of ten higher than the annual dose of 50 mrem, upon which the concentrations in the new 10CFR20, Appendix B, Table 2, Column 2, are based. Compliance with the limits of the new 10CFR20.1301 will be demonstrated by operating within the limits of 10CFR50, Appendix I and 40CFR190.
The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs).

BASES The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents.
The minimum flow devices for EMFs listed in Table 16. 11.2-1 are required to provide assurance of representative sampling during actual or potential releases of liquid effluents.
An interlock between the EMF's minimum flow device and its associated flow rate measurement device disables the remove alarm during non-release timeframes for the purpose of the control room black board annunciator criteria that disable expected alarms. An EMF flow rate measurement device measures total flow of the effluent while the EMF minimum flow device measures the sample flow rate through the EMF. The Alarm/Trip Setpoints of these instruments shan be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the Alarm!Trip will occur prior to exceeding the limits stated in SLC 16.11.1. The FUNCTIONALITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50. The Turbine Building Sump to RC Discharge Flow Measurement and Sampler Devices are for monitoring only and do not alarm or have any controls that require a COT. REFERENCES

BASES FREQUENCY 31 days This commitment is provided to implement the requirements of Sections II.A, Ill.A and IV.A of Appendix I, 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. These requirements are applicable only if the drinking water supply is taken from the river 3 miles downstream of the plant discharge.
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 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.

Each batch to be -transferred to the chemical treatment ponds is limited by: I Q J < 6.0 x I os pCi I gm j (C 1 x 10) µCi/ ml The inventory limits of the chemical treatment ponds (CTP) are based on limiting the consequences of an uncontrolled release of the pond inventory.
The expression in SLC 16.11.5 assumes the pond inventory is uniformly mixed, that the pond is located in an uncontrolled area as defined in 10 CFR Part 20, and that the concentration limit in Note 4 to Appendix B of 1 O CFR Part 20 applies. The batch limits of slurry to the chemical treatment ponds assure that radioactive material in the slurry transferred to the CTP are "as low as is reasonably achievable" in accordance with 10 CFR Part 50.36a. The expression in SLC 16.11.5 assures no batch of slurry will be transferred to the CTP unless the sum-of the ratios of the activity of the radionuclides to their respective concentration limitation is less than the ratio of the 1 O CFR Part 50, Appendix I, Section 11.A, total body dose level to the instantaneous whole body dose rate limitation, or that: I c 1 < 3 mrem I yr = 0_006 j (C 1 x10) 500 mrem/ yr Where: c i = Radioactive slurry concentration for radionuclide "j" entering the UNRESTRICTED AREA chemical treatment ponds, in microCuries/milliliter; and Ci = 10 CFR 20, Appendix B, Table 2, Column 2, concentration for single radionuclide "j" , in microCuries/milliliter.

For the design of filter/demineralizers using powder resin, the slurry wash volume and the weight of resin used per batch is fixed by the cell surface area, and the slurry volume to resin weight ratio is constant at 100 ml/gram of wet, drained resin with a moisture content of approximately 55 to 60% (bulk density of about 58 pounds per cubic feet). Therefore, L c L: Q __ .! __ = J < 0.006, and j (C 1 x 10) j (C 1 x 10) (10 2 ml/ gm) (10 6 pCil µCi) Where: L: Q J < 6.0 x 1 as pCi I gm j(C 1 x10) µCi/ml Q 1 = concentration of radioactive materials in wet, drained slurry (powdex resin) for radionuclide 11 j", excluding tritium, dissolved or entrained noble gases, and radionuclides with less than an 8-day half-life.
The analysis shall include at least Ce-144, Cs-134, Cs-137, Co-58 and Co-60, in picoCuries/gram.
Estimates of the Sr-89 and Sr-90 batch concentration shall be included based on the most recent monthly composite analysis (within 3 months); and Ci = 10 CFR 20, Appendix B, Table 2, Column 2, concentration for single radionuclide 11 j", in microCuries/milliliter.
The batch limits provide assurance that activity input to the chemical treatment ponds will be minimized, and a means of identifying radioactive material in the inventory limitation of SLC 16.11.5. The basic requirements for the Selected Licensee Commitments concerning effluents from nuclear power reactors are stated in 1 OCFR50.36a.
These requirements indicate that compliance with effluent Selected Licensee Commitments will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 1OCFR20.106 (new 1 OCFR20.1301
). 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 10CFR20.106 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 10CFR50.36a 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 1 OCFR50, Appendix I. McGuire Units 1 and 2 16.11.5-3 Revision 0 BASES (continued)
Chemical Treatment Ponds 16.11.5 As stated in the Introduction to Appendix B of the new 10CFR20, the 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 1 OCFR50, 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/McGuire/Oconee has demonstrated that the use of the concentration values associated with the old 1OCFR20.106 as SLC limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the limits of 1 OCFR50, Appendix I. Therefore, the use of concentration values which correspond to an annual dose of 500 mrem should not have a negative impact on the ability to continue to operate within the limits of 1 OCFR50, Appendix I and 40CFR 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 1 OCFR20, 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 1 OCFR20, 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 1 OCFR20, Appendix B, Table II, Column 2 are based, is a factor of ten higher than the annual dose of 50 mrem, upon which the concentrations in the new 10CFR20, Appendix B, Table 2, Column 2, are based. Compliance with the limits of the new 1 OCFR20.1301 will be demonstrated by operating within the limits of 10CFR50, Appendix I and 40CFR190.

McGuire Units 1 and 2 16.11.6-5 Revision 137 BASES Dose Rate -Gaseous Effluents 16.11.6 Specific 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 3000 mrem/year to the skin from noble gases, and 1500 mrem/year to any organ from Iodine 131, Iodine 133, tritium, and all radionuclides in particulate form with half-lives greater than eight days. This commitment applies to the release of gaseous effluents from all reactors at the site. The Exclusion Area Boundary (Site Boundary) is set as the boundary for gaseous effluent release limits. The Exclusion Area Boundary (EAB) is formed by a 2500 ft radius centered on the Reactor Buildings' centerlines as shown on Figure 16.11.1-1.
The basic requirements for the Selected Licensee Commitments concerning effluents from nuclear power reactors are stated in 1 OCFR50.36a.
These requirements indicate that compliance with effluent Selected Licensee Commitments will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 1OCFR20.106 (new 1 OCFR20.1301
). 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 1OCFR20.106 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 10CFR50.36a 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 10CFR50, Appendix I. As stated in the Introduction to Appendix B of the new 10CFR20, the effluent concentration (EC) limits given in Appendix 8, Table 2, Column 1, are based on an annual dose of 50 mrem for isotopes for which inhalation or ingestion is limiting or 100 mrem for isotopes for which submersion (noble gases) is limiting.
Since release concentrations corresponding to limiting dose rates of less than or equal to 500 mrem/year to the whole body, 3000 mrem/year to the skin from noble gases, and 1500 mrem/year to any organ from Iodine 131, Iodine 133, tritium and for all radionuclides in particulate form with half-lives greater than eight days at the site boundary has been acceptable as a SLC limit for gaseous effluents to assure that the limits of 1 OCFR50, Appendix I and 40CFR190 are not likely to be exceeded, it should not be necessary to restrict the operational flexibility by incorporating the EC value for isotopes based on ingestion/inhalation (50 mrem/year) or for isotopes with the EC based on submersion (100 mrem/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 10CFR20, Appendix 8, Table 2, Column 1, relate to a dose of 50 or 100 mrem in a year. When applied on an instantaneous basis, this corresponds to a dose rate of either 50 or 100 mrem/year. These low values are impractical upon which to base effluent monitor setpoint calculations for many 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 16.11.6 will be maintained at the current dose rate limit for noble gases of 500 mrem/year to the whole body and 3000 mrem/year to the skin, for Iodine 131, Iodine 133, tritium and all radionuclides in particulate form with half-lives greater than eight days an instantaneous dose rate limit of 1500 mrem/year to any organ. McGuire Units 1 and 2 16.11.6-6 Revision 137 BASES (continued)
Dose Rate -Gaseous Effluents 16.11.6 Compliance with the limits of the new 1 OCFR20.1301 will be demonstrated by operating within the limits of 1 OCFR50, Appendix I and 40CFR190.
Operational history at Catawba/McGuire/Oconee has demonstrated that the use of the dose rate values listed above (i.e. 500 mrem/year, 3000 mrem/year and 1500 mrem/year) as SLC limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the limits of 1 OCFR50, Appendix I and 40CFR 190. The required detection capabilities for radioactive materials in gaseous waste samples are tabulated in terms of the lower limits of detection (LLDs). 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

McGuire Units 1 and 2 16.11.7-8 Revision 134 I BASES Radioactive Gaseous Effluent Monitoring Instrumentation 16.11.7 The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents.
The instrumentation consists of monitoring and sampling instrumentation.
Monitors provide continuous display of process parameters with appropriate alarms and trip setpoints established.
Samplers collect a portion of the desired process for subsequent laboratory analysis, and do not have alarm/trip capability.
Samplers and the analysis program provide a method to assure that long term effluent release quantities do not exceed the requirements of SLC 16.11.6. Monitors provide assurance that instantaneous effluent releases do not exceed the requirements of SLC 16.11.6. The minimum flow devices for EMFs listed in Table 16.11. 7-1 are required to provide assurance of representative sampling during actual or potential releases of gaseous effluents.
The flow rate monitor quantifies the total gaseous effluent (both non-radioactive and radioactive) released to the environment.
During routine sampling, instrumentation may be turned off for short periods of time (not to exceed 15 minutes) in order to meet analysis requirements of SLC 16.11.6. This is considered to be a normal function of the equipment.
The Alarm/Trip Setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the Alarm/Trip will occur prior to exceeding
- the limits stated in SLC 16.11.6. The FUNCTIONALITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50. REFERENCES

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 specifications for lodine-131 and 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 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.

This commitment implements the requirements of 19 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objectives given in Section 11.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 Section 11.B and 11.C of Appendix I, 10 CFR Part 50, for gaseous effluents.
This commitment applies at all times to the release of radioactive materials in gaseous effluents from each unit at the site. For units with shared Radwaste Treatment Systems, the gaseous effluents from the shared system are to be proportioned among the units sharing that system in accordance with NUREG-0133, Chapter 3.1.

BASES FREQUENCY When calculated doses from effluent releases exceeds twice the limits of SLCs 16.11.3, 16.11.8 or 16.11.9 This commitment 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 specification requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation 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 ()F THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of 10 CFR Part 50, Appendix I, and if direct radiation doses from the units and outside storage tanks are kept small. This Special Report, as defined in 10 CFR Part 20.2203(a)( 4 ), shall include an analysis that estimates the radiation exposure (dose) to a MEMBER ()F 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.
If the dose to any MEMBER ()F 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 McGuire Units 1 and 2 16.11.12-2 Revision 67 BASES (continued)

Refer to NUREG-0133, "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 hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, every 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. It is recognized that, at times, it may not be possible or practical 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 an Licensee Event Report, identify the cause of the unavailability of samples for that pathway and identify the new locations(s) for obtaining replacement samples in the next Annual 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 forty 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 sections 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 with minimal fading. 3. The purpose of this sample is to obtain background information.
If it is not practical to establish control locations in accordance with the distance and wind direction criteria, other sites that provide valid background data may be substituted.

McGuire Units 1 and 2 16.11.13-12 Revision 137 BASES Radiological Environmental Monitoring Program 16.11.13 The Radiological Environmental Monitoring Program is established to monitor the radiation and radionuclides in the environs of the plant. The program provides representative measurements of radioactivity in the highest potential exposure pathways, and verification of the accuracy of the effluent monitoring program and modeling of environmental exposure pathways.
The program is contained in SLC 16.11.13 -16.11.16 and conforms to the guidance of Appendix I to 10 CFR Part 50. The program includes the following:
- 1. Monitoring, sampling, analysis, and reporting of radiation and radionuclides in the environment in accordance with the methodology and parameters in the ODCM, 2. A Land Use Census to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the monitoring program are made if required by the results of this census, and 3. Participation in an lnterlaboratory Comparison Program to ensure that independent 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.
The portion of the Radiological Environmental Monitoring Program required by this commitment 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 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.
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 16.11.13-3 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 McGuire Units 1 and 2 16.11.13-13 Revision 137 Radiological Environmental Monitoring Program 16.11.13 BASES (continued) 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 SLCs 16.11.6, 16.11.8, and 16.11.9.

McGuire Units 1 and 2 16.11.14-2 In the next scheduled Annual Radiological Release Report FREQUENCY 12 months Revision 21 BASES Land Use Census 16.11.14 This commitment 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, 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 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., similar to lettuce and cabbage), and (2) a vegeta.tion yield of 2 kg/m 2. With a land use census identifying a location(s) which yields a calculated dose or dose commitment (via the same exposure pathway) 20% greater than at a location from which samples are currently being obtained in accordance with SLC 16.11.13, add the new location to the Radiological Environmental Monitoring Program. The sampling location(s), excluding the control station location, having the lowest calculated dose or dose commitment (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.

McGuire 2014 ARERR-Ground Water Well Tritium Data 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, McGuire Nuclear Station monitored 91 wells, 7 surface water points, and l landfill leachate pond sample in 2014. Wells are typically sampled quarterly or semi-annually.
Ground water samples are regularly analyzed for tritium and gamma emitters, with select wells being analyzed for difficult-to-detect radionuclides.
No gamma or difficult-to-detect radionuclides, other than naturally occurring radionuclides, were identified in any samples during 2014. Results from sampling during 2014 confirmed existing knowledge of tritium concentrations in site ground water. Lining of the Conventional Waste (WC) Ponds was performed in 201 l and 2012 along with WC piping replacement in 2013 and 2014. Tritium concentrations in wells near these ponds have continued to decrease.
No events meeting the criteria for voluntary notification per NEI 07-07, Industry Ground Water Protection Initiative, occurred at McGuire in 2014.

1 WPFT5120 NON-FUNCTIONAL DATE: 9/19/2014 Reason: channel calibration discrepancy Duration out of service: Out of service 9/19/2014
-3/04/2015 Function:
turbine building sump to condenser circulation water (RC) flow rate measurement Regulatory Requirement:
Flow Rate Measurement Device for turbine building sump to RC pathway Summary: 1 WPFT5120 is the turbine building sump to condenser circulation water (RC) flow rate measurement device required per SLC 16.11.2 function 4.d with "At all times" applicability.
A testing requirement, TR 16.11.2.6, requires performing a CHANNEL CALIBATION at an 18 month frequency.
To perform this channel calibration, flow rate measurement by 1WPFT5120 is compared to sump volume. Flow through this release pathway is only configured when turbine building sump discharge is aligned from the normal discharge pathway (Conventional Waste System (WC) to the alternate discharge path (RC cross-over header). To perform this channel calibration the turbine building sump must be aligned to RC with work order assigned to responsible maintenance team to perform channel calibration per procedure.
WO 2124354 was scheduled during 1EOC23 to perform this testing on 1WPFT5120.
The channel calibration was already into grace period with a late date of 9/19/2014.
Initial data collection performed on 9/04/2014 by maintenance indicated there was a discrepancy between sump monitor and sump volume, precluding satisfactory completion of procedure.
Engineering assistance was requested by maintenance to evaluate data and determine scope of repair. Operations realigned turbine building sump discharge pathway back to the normal alignment to WC. A misunderstanding of the required function per SLC 16.11.2 for 1 WPFT5120 resulted in a TSAIL classification error. Two TSAIL entries (Ml-14-02307 and Ml-14-02335) were created for Turb. Bldg. Sump Discharge Flow Totalizer.
Ml-14-02335 indicated 1WPFT5120 as Non-functional with required Functional dates/times (30 day SLC remedial action time) and this entry was classified as active entry. Ml-14-02335 was closed to Ml-14-02307; however, Ml-14-02307 did not include required Functional date/time and this entry was classified as tracking entry. Ml-14-02307 should have had a 30 day required Functional date/time and not be classified as a tracking entry. When the channel calibration surveillance went late, it was not recognized by the station that this non-functional condition existed for 1WPFT5120 flow monitor. This action precluded the station from placing appropriate priority on performing the necessary work to restore instrumentation to functional status within the required 30 day time period.
On 01/06/2015 the work control PM coordinator discovered the required surveillance was not completed in 1EOC23, resulting in channel being non-function per SLC 16.11.2 function 4.d. A corrective action report (PIP M-15-00111) was generated at that time. Because of the extended time period, the 30 days had already expired and reporting would be required in Annual Radioactive Effluent Release Report (ARERR). The alternate release pathway has not been utilized for any radioactive effluent releases since turbine building sump discharge was realigned to WC. Since RC discharge pathway has not been utilized, functionality of this flow rate measurement device has not required compensatory measures to estimate discharge volume. The lack of prioritization of repair was recognized as adverse to quality and corrective action report (PIP M-15-01724) was generated with action taken to place appropriate priority on restoration of this functional instrumentation.
Restoration of 1WPFT5120 to FUNCTIONAL status is tracked under PIP M-15-00111 CA#006.
