SUMMARY

0 Initial issue ofcalculation to evaluate the impact on IOCFR5O Appendix I, IOCFR2O and 4OCFRI9O design objectives of permanently bypassing the Offgas Filter Unit (OGFU) of the Steam Jet Air Ejector process stream.

I ANALYSIS NO. BYR16-012 REVISION: 0 Page 5 of 40 1.0 PURPOSE and SCOPE The purpose of this calculation is to verify continued compliance with the design objectives of I OCFR5O Appendix I (Ref.4.1) in support of the permanent bypassing of the Off Gas Filter Unit (OGFU) (1 OGOI S) under EC 402667, Rev. I .This calculation provides the following evaluations, as required by Off-Site Dose Calculation Manual Section 5.4 ofthe Offsite Dose Calculation Manual, (ODCM, CY-BY-170-301, Revision 12, Ref. 4.2) in support of a major change to the Gaseous Radwaste Treatment Systems:

I . An evaluation of the change which shows the predicted releases of radioactive materials in gaseous effluents that differ from those previously predicted in the License application and amendments.

2. An evaluation of the change, which shows the expected maximum exposures to a member of the public and to the general population that differ from those previously estimated in the License application and amendments while in continued compliance with Appendix I.

In addition, compliance with IOCFR2O (Ref. 4.3) dose criteria and airborne concentration will be verified in this calculation as well as compliance with 4OCFRI9O (Ref.4.1O)

The OGFU does not perform a safety related or accident mitigation function. The OGFU, however, was credited in the analysis presented in UFSAR Section 1 1 .2, Table I 1.2-2, UFSAR, Revision 1 0, 2004 (Ref. 4.4) and UFSAR Section 1 1 .3, Subsection I I .3.3.4 Revision 9, 2002 (Ref. 4.5) to demonstrate compliance with 1 OCFR5O Appendix I criteria to maintain dose to the general public as low as reasonably achievable as a result of the release of gaseous and liquid effluents. Note that Subsection I I .3.3.4 references the use of the PWR GALE computer program (NUREG-0017) and PWR-GALE input parameters tabulated in Table I I .2-2, UFSAR, Revision JO, 2004 (Ref. 4.4).

To demonstrate continued compliance with these criteria, the results ofthe NUREG-0017 Revision 0 (Ref. 4.6) source terms presented in Table I I .3-7 of the UFSAR, Revision 5, 1995 are adjusted to eliminate the iodine removal mechanism provided by the OGFU. Note that the expected annual airborne release via the station vent stack is tabulated in UFSAR Table I I .3-7, Revision 5, 1 994 in units of Ci/yr and reproduced and modified for this analysis as Table 2.1-3. Table 2.1-3 is a composite table of UFSAR Table 11.3-6, Revision 1, 1989 with an unfiltered I-I 31 and I-I 33 release inserted and UFSAR Table I I .3-f, Revision 5, 1 994 with the annual release of the Volume Reduction System shown in UFSAR Table I I .3-6, Revision I, 1989 removed.

Off-site doses are then calculated using the ODCM computer program, RETDAS, which utilizes a methodology consistent with that specified in Regulatory Guide I I 09 Revision I (Ref. 4.7). NUREG-OOIf Revision 0 and Regulatory Guide 1.109 Revision I specifythe criteria to demonstrate compliance with the design objectives of IOCFR5O Appendix I during plant licensing.

It should be noted that the NRC did not credit the OGFU in their calculations to verify Byron and Braidwood Stations compliance with IOCFR5O Appendix I in the NRCs initial safety

ANALYSIS NO. BYR16-012 REVISION: 0 Page 6 of 40 I

evaluation reports (SERs) (Ref. 4.12). More details are provided in Chapter 11 of Reference 4.12, Page 11-4. The NRC calculations concluded that the Byron Station Gaseous Radwaste Treatment Systems satisfied the design objectives of I OCFR5O Appendix I without the iodine removal capability of the OGFU.

In addition, radioactive liquid releases into the Byron discharge canal based on UFSAR Table 1 1 .2-1 Revision I 2, December 2008 are utilized as input to the Byron ODCM computer program RETDAS to produce liquid dose consequences as part of the Appendix I, JOCFR2O and 4OCFRI9O compliance demonstrated in this analysis. The 4OCFRJ9O compliance also contains a direct dose component from such contained sources as the ISFSI and the containment, which is further discussed in Section 2.13 ofthis calculation.

BYRI6-012 is a non-safety related calculation and the affected system is the Off Gas tOG) system. The initiating document is EC 402667, Rev. I Based on the guidance provided in Attachment C, ODCM computer program RETDAS outputs individual computer runs specific to Appendix I airborne and liquid releases, IOCFR2O instantaneous gaseous releases and 4OCFRI9O airborne and liquid releases. Attachment C also provides guidance that the RETDAS reports provided by Byron Station contain applicable results that are annual in nature, except for the instantaneous reports.

2.0 CALCULATION INPUTS 2.1 The total filtered annual iodine release is presented in UFSAR Table 11.3-6, UFSAR, Revision I I 989 (Ref. 4.5), (Attachment E) and presented as follows:

Based on the PWR-GALE inputs listed in Table I I .2-2 of the UFSAR, Revision IC, 2004 (Ref. 4.4), the OGFU filter efficiency is equivalent to 90%, 1 0% of the iodine is released to the environment, a release fraction of 0. 1 0. The impact of not crediting the OGFU is to release 100% of iodine in the SJAE process stream to the environment, which is accomplished by increasing the annual iodine release rate from the SJAE by a factor of 10. See Table 2.1-2.

Note that the annual iodine release rate from the remainder of the plant systems remains unchanged regardless of the filtration or non-filtration of the SJAE process stream by the

• See Table 2.1-2 The data in Columns B (filtered) and C (unfiltered) ofTable 2.1-3 are entered into the ODCM computer program RETDAS by Byron personnel to calculate doses to verify compliance with the airborne aspects of IOCFR5O Appendix I, IOCFR2O and 400FRI9O. Attachments F, G, H, I, J, K, L, M, P, Q and R contain the computer outputs provided by Byron on a per unit or per site basis as indicated by RETDAS, (filtered and unfiltered by the OGFU). The tables beginning in Section 2. 1 0 summarize the results of the ODCM calculation for one unit and each case, unfiltered and filtered (the input data for both units are identical). Quarterly doses are not tabulated as compliance is demonstrated by the annual dose.

Note that the explanation of Attachments is provided in the Table of Contents.

2.2 The fraction of iodine released from the main condenser air ejector is 0.10, UFSAR Table 1 1 .2-2 Revision I 0 December 2004 (Ref. 4.4). This corresponds to a OGFU filter efficiency of 90%, an iodine retention factor 0.9.

2.3 Maximum Vent Release IQ at the Byron Unrestricted Area Boundary is 4.497E-07 sec/m3 for the SSE sector as tabulated in Table 4-1 of the ODCM, CY-BY-170-301 Revision ,

12 (Ref. 4.2).

2.4 Maximum Vent Release IQ at the Byron Restricted Area Boundary is I .441 E-06 sec/m3 as tabulated in Table 4-2 ofthe ODCM, CY-BY-170-301 Revision 12 for the S sector (Ref. 4.2).

2.5 As described in the Byron ODCM, CY-BY-170-301, Revision 12, Regulatory Dose Limit Matrix, Table I -1 compliance with I OCFR2O involves a gaseous effluent component and a liquid component. Table I I .3-6 of the Byron UFSAR, Revision I I 989, (Ref. 4.5) (Attachment E) is the expected gaseous effluent annual release via the vent stack per unit, in units of Curies/year (Ci/yr), involving a breakdown ofthe various contributors. Tables 2.1-1, 2.1-2 and 2.1-3 are modifications ofthis table showing the individual isotopes discharged into the atmosphere, filtered and unfiltered by the OGFU, in units of Ci/yr and pCi/yr.

I ANALYSIS NO. BYR16-012 REVISION: 0 Page 11 of4O 2.7 Based on the Byron guidance provided in Attachment C, regulatory compliance is demonstrated by RETDAS outputs in the following manner:

a. The gaseous and liquid annual reports demonstrate I OCFR5O Appendix I (per unit compliance), Attachments F and G (Gaseous-Unfiltered), Attachments P and Q (Gaseous-Filtered) and Attachments J and K (Liquid).

b. The 4OCFRI9O report demonstrates the 4OCFRI9O (site) compliance, Attachments L (Unfiltered) and M (Filtered).

c. The gaseous instantaneous report demonstrates IOCFR2O (site) compliance, Attachments H (Unfiltered) and I (Filtered) by the OGFU, respectively.

2.8 The Unit I and Unit 2 vent stack flow rates are 151842 ft3/min for Byron Unit I and 147042 ft3/min for Byron Unit 2. These values are documented in ODCM CY-BY-1ZO-301 Revision 12 Figure 2-1 and UFSAR Section 11 .3, Revision 9, 2002.

2.9 As described in the B/B UFSAR, Section 11.2.1.3, Revision 15, December 2014, the Byron power uprate has very minimal impact on normal operational liquid release source terms. The following extractions are from the Byron/Braidwood UFSAR:

For liquid releases: Core uprate results in a maximum potential increase of 0.6% in the liquid effluent release concentrations previously reported. Taking into consideration the accuracy and error bounds ofthe operational data utilized in NUREG 00017, this small percentage change is well within the uncertainty of the calculated results of the original NUREG 0017 based expected liquid effluent concentrations presented in Table 11.2-4 which remain valid for uprate.

Note that the Expected Release column of UFSAR Table I I .2-4, Revision 7, December 1998 is the rounded version of the Total column of UFSAR Table I I .2-1 Therefore, Table I 1.2-1 of the Byron UFSAR, Revision 12, December 2008 remains valid for power uprate.

As described in the B/B UFSAR, Section 1 1.3.3.4, Revision 15, December 2014, the Byron power uprate has very minimal impact on normal operational gaseous release source terms.

The following extractions are from the Byron/Braidwood UFSAR:

For airborne releases, Core uprate results in a maximum potential increase of 0.6% for long lived isotopes such as Kr 85. Shorter lived isotopes will have reduced releases or only slight increases as compared to the 0.6% increase in power level. The impact of power uprate on iodine releases is limited to a maximum of 0.6%. The other components of gaseous releases (particulates via the building ventilation systems and water activation gases) are not impacted by uprate. All of the incremental tritium production due to power uprate is assumed to be released via the gaseous pathway resulting in an approximate 0.8% increase in tritium releases via the gaseous pathway. Taking into consideration the accuracy and error bounds of the operational data utilized in NUREG 00017, these small percentage changes are well within the uncertainty of the calculated results of the original NUREG 0017 based maximum offsite airborne concentrations from gaseous radwaste effluents presented in Tablel 1.3-7.

2.10 The annual gaseous effluent results for IOCFR5O, Appendix I compliance applicable to Unit I and Unit 2 are provided in Attachment F and Attachment G (Unfiltered) and Attachments p and Q (Filtered), respectively. Note that there is a variation in terminology between Attachment N and the annual effluent reports, though they address the same subject. The Attachment N terminology Organ Dose Due to Specified Non-Noble Gas Radionuclides translates to Iodine and Particulates in the RETDAS annual gaseous effluent reports, since iodines and particulates are non-noble gases. Depending on the effluent mix, RETDAS prints the results for the appropriate critical organ and age group. For example, see Table 2.10-2.

I ANALYSIS NO. BYR16-012 REVISION: 0 Page 19 of4O 3.0 ASSUMPTIONS 3.1 As described in the UFSAR Table 11.3-6, Revision 6 1996, the Volume Reduction System is not used at Byron Station. Therefore, the off-site release contributions from this system, as listed in UFSAR Table I I .3-6 of the UFSAR, Revision 6, 1996 for this system will not be included in the dose calculations.

3.2 No activity adjustments are made for noble gas and particulate radioactive isotopes for calculations that assume that the OGFU is not in service. The methodology in the NUREG 0017 only credits the OGFU for iodine removal and noble gases and particulates are not affected by the OGFU. Item 44 of Table I I .2-2 describes Fraction of iodine released from the main condenser air ejector as 0.10. An iodine release fraction of 0.10 numerically translates to a charcoal filter removal efficiency of 90%, a retention fraction of 0.9. This concept is confirmed in UFSAR Section 10.4.2, Revision 9 December 2002 with the following statement, decontamination factor for the charcoal filter is a minimum of I 0 for iodine. No retention of noble gases or particulates are discussed. Additionally, Section 2.2.12 of NUREG-OO1Z (Ref.

4.6) discusses iodine removal only by charcoal filtration and particulate removal only by HEPA filtration.

3.3 Maximum relative concentration factors, xQ, are conservatively used in this calculation to determine airborne concentrations at the Restricted and Unrestricted Boundaries..

3.4 The requirement in ODCM Revision 12 Section 4.1.5 to operate the appropriate Ventilation Exhaust Treatment Systems to reduce the release of radioactivity when projected doses in a 31 day period from each unit will exceed

a. 0.2 mrad to air from gamma radiation

b. 0.4 mrad to air from beta radiation

c. 0.3 mrem to any organ of a member of the public is not a IOCFR5O Appendix I design criteria and will not be used as an acceptance criteria for this calculation. In addition to the ODCM, the above text of Section 3.4 is based on the review of References 4.1 4.2, 4.3 and 4.9, which demonstrates that Items a, b, c, are not Appendix I design criteria.

3.5 Doses based on liquid releases to the environment are conservatively based on liquid releases to the discharge canal, no additional river dilution. See UFSAR Table 1 1 .2-3. This is assumed to be the unrestricted area boundary.

5.0 COMPUTER PROGRAM Byron personnel executed their ODCM computer program, RETDAS Version 3.6.4.9, on the Byron site with input airborne and liquid release data provided via Sargent & Lundy E-mail. As part of the Sargent & Lundy calculation QA based review process, airborne and liquid releases from the UFSAR, data from the ODCM and calculated data here-in were reviewed against the RETDAS computer outputs used by Attachments F, G, H, I, J, K, L, M, P, Q and found acceptable. Note that Attachments F, G, P and Q contain the input summary of the gaseous release isotopic RETDAS input, while Attachments J and K contain the input summary of the liquid release isotopic RETDAS input. The IOCFR2O compliance gaseous instantaneous RETDAS computer outputs, Attachments H and I, and the 40CFR190 compliance RETDAS computer outputs, Attachments L and M, do not explicitly repeat the isotopic inputs, but use the corresponding gaseous and liquid release inputs in the gaseous and liquid RETDAS computer runs. As part of the documentation, the attachments noted above have been retransmitted as part ofTODI BYR-16-044 (Ref.4.15).

6.0 METHODOLOGY 6.1 Airborne Releases to the Environment via the Station Vent Stack UFSAR Table I I .3-6, UFSAR, Revision I I 989 lists the curies of radioactive nuclides released per year from several plant systems. Refer to Attachment E.

The gaseous effluent contribution from the air ejector exhaust includes two radioactive iodine isotopes, I-I 31 and 1-133. The data for the air ejector exhaust in Table I I .3-6, of the UFSAR, Revision I I 989 reflects the 90% removal capability of the OGFU. To obtain the unfiltered release of radioactive iodine via the air ejector exhaust, the annual curie released data for I-131 and 1-133 via this path is multiplied by a factor of 10. New annual release values for isotopes I-I 31 and I-I 33 are then calculated by including the contribution of these isotopes from other plant systems. See Table 2.1-1, Table 2.1-2 and Table 2.1-3.

The annual curie (converted to microcuries) release data for each radioactive isotope in Table 11.3-7, UFSAR, Revision 5, 1994 filtered and adjusted for unfiltered, is entered in the ODCM computer program RETDAS (Ref. 4.8) to provide a comparison in the offsite doses for the SJAE process stream being filtered by the OGFU and bypassing the OGFU. The resulting doses can be compared to IOCFR5O Appendix I, IOCFR2O and 4OCFRI9O limitations for gaseous releases to the environment to determine acceptability. Note that the expected annual airborne release via the station vent stack is tabulated in UFSAR Table I I .3-7, Revision 5, 1994 in units of Ci/yr and reproduced and modified for this analysis as Table 2.1-3. Table 2.1-3 is a composite table of UFSAR Table I I .3-6, Revision I I 989 with an unfiltered I-I 31 and I-I 33 release inserted and UFSAR Table I I .3-7, Revision 5, 1 994 with the annual release of the Volume Reduction System shown in UFSAR Table I 1 .3-6, Revision I I 989 removed.

The maximum airborne concentration at the site boundaries (Restricted Area Boundary and Unrestricted Area Boundary) for 1-131 and I-I 33 are calculated based on the output of the

I ANALYSIS NO. BYR16-012 REVISION: 0 Page 22 of 40 RETDAS computer program. Occupational DAC limits are for plant personnel and applied at the Restricted Area Boundary and the effluent concentration limits are applied at the Unrestricted Area Boundary for the general public.

Using the guidance of Attachment R, the dose point for mixed mode gaseous releases via the vent stack for instantaneous and annual dose assessment is the point of maximum xQ on the Unrestricted Area Boundary. From visual inspection of Table 4-1 of the ODCM ( CY-BY-1 70-301 Revision 12), the maximum vent IQ at the unrestricted boundary is 4.497E-07 sec/rn3 in the SSE sector. This applies to the effluent concentration limits for the general public at the unrestricted boundary.

As a section of the RETDAS output NUCLIDE DATA, shown in Attachments F and G and Attachments P and Q for the gaseous annual releases, isotopic concentrations in the airborne effluent are tabulated in units of pCi/cc, which is equivalent to pCi/mi for this analysis. This is the 1-131 and -133 concentrations released from the vent stack. The maximum concentrations are calculated at the Unrestricted Area Boundary for OGFU filtered and filter bypass releases by multiplying the vent stack concentrations by the maximum <IQs in Table 4-1 of the ODCM.

The DAC applies at the Restricted Area Boundary and is applicable to plant personnel. Since the dose point at the Restricted Area Boundary is impacted by the same gaseous vent effluent as the dose point at the Unrestricted Area Boundary in Attachments F and G and P and Q, iodine concentrations at the Restricted Area Boundary vary by the ratio of xIQs. The maximum XIQ at the Restricted Area Boundary tabulated in Table 4-2 of the ODCM (CY-BY-1 70-301, Revision 12) is 1.441E-06 sec/m3 in the S sector. Though the dose points for comparison are not at the same location, it is conservative to apply the ratio of maximum IQs to the REIDAS iodine concentrations at the Unrestricted Area Boundary in order to maximize the iodine concentrations at the Restricted Area Boundary.

X/Q ratio = I .441 E-0614.497E-07 3.20 The gaseous release aspects ofAppendix I, 10CFR2O and 4OCFRI9O analyses utilize the vent stack releases tabulated in UFSAR Table I I .3-7, Revision 5, 1 994 on a per unit basis or per station basis. Those analyses that are per unit basis utilize the releases via one vent stack as RETDAS input. Those that are on a per site basis utilize the releases from two vent stacks. For simplicity, the vent stacks are postulated to have the same volumetric flow rate. Releases on a per station basis increases the activity released, but preserves the isotopic concentration since the curies released are doubled, but so is the volumetric flow rate.

6.2 Liquid Releases to the Environment via the Discharge Canal The annual releases into the discharge canal are utilized in Byrons ODCM computer program RETDAS in units of pCi/mi. As extracted from Attachment R, Liquid doses are not calculated at a specific location like gaseous effluents but are based on the concentration of radioactivity in liquid effluents released to unrestricted areas as defined in ODCM Table 1-1. The dose from radioactive materials in liquid effluents is calculated from the consumption of fish and potable water as defined in ODCM Section 3.4.1 There is a potable intake water near-field dilution factor defined in section 3.4.2, which assumes the potable water intake is at least % mile downstream. Fish intake is assumed to occur at the discharge structure after a mixing factor is applied as defined in Section 3.5.5.

[ ANALYSIS NO. BYR16-012 REVISION: 0 Page 23 of 40 The liquid release aspects ofAppendix I, IOCFR2O and 4OCFR19O analyses utilize the liquid release into the discharge canal tabulated in UFSAR Table I I .2-2, Revision I 0, 2004 on a per unit basis or station basis. Those analyses that are per unit basis utilize the liquid releases discharged by one unit as RETDAS input. Those that are on a per site basis utilize the discharge releases from two units. For simplicity, the two discharges are postulated to have the same release rate. Releases on a per site basis increases the activity released, but preserves the isotopic concentration since the curies released are doubled, but so is the volumetric dilution rate. RETDAS utilizes the liquid releases to determine Appendix I, IOCFR2O and 4OCFRI9O compliances.

The RETDAS results for liquid releases from Unit I and Unit 2 are presented in Attachments J and K, respectively. Liquid releases are not filtered by the OGFU, whether the SJAE process stream is filtered through or bypasses the OGFU.

Column C above represents the release to the environment with the SJAE process stream bypassing the OGFU. Only 1-131 and 1-133 in the SJAE process stream are increased by a factor of 10 as a result of bypassing the OGFU. The other isotopes are not.

I ANALYSIS NO. BYR16-012 REVISION: 0 Page 26 of4O Comparing Table 2.1-1 and Table 2.1-2 yields the numerical logic for calculating the annual release rate for 1-131 and 1-133 from the bypassed OGFU and the remaining equipment shown in UFSAR Table I I .3-6, Revision I 1 989. Note that the expected annual airborne release via the station vent stack is tabulated in UFSAR Table I I .3-7, Revision 5, 1 994 in units of Ci/yr and reproduced and modified for this analysis as Table 2.1-3. Table 2.1-3 is a composite table of UFSAR Table I I .3-6, Revision , 1989 with an unfiltered I-I 31 and 1-1 33 release inserted and UFSAR Table I 1 .3-f, Revision 5, 1 994 with the annual release of the Volume Reduction System shown in UFSAR Table I I .3-6, Revision 1 I 989 removed.

As described in Attachment A, the Byron ODCM computer program RETDAS requires airborne effluent input in units of pCi/cc. The units of Table 7. 1 -1 require conversion from Ci/yr to pCi/cc.

By cross-checking Figure 2-1 ofthe ODCM, CY-BY-lfO-301 Revision 12 against Section 11.3 of the UFSAR, Revision 9, 2002 the vent stack flows are I 51 842 ft3/min for Byron Unit I and 14f042 ft3/min for Byron Unit 2. Per Input 2.8, these values are design input and can be used to determine radionuclide concentration in the vent stack effluent.

Using Unit 2 stack flow in this analysis will yield a higher effluent concentration since it is the lower value.

Unit 2 Stack Flow = 14f042 ft3/min x (30.48 cm)3/ft3 x 60 mm/hr x 24 hr/day x 365 day/yr

= 2.18E+15 cc/yr Concentration example from Table fl-i Using 1-131 Concentration of unfiltered 1-131 in vent stack 7.60E+04 pCi/yr/(2.18E+15 cc/yr) 3.49E-1 I pCi/cc This corresponds to Table f.l-l, accounting for rounding between spreadsheet and calculator.

Therefore, the vent stack concentration is the input to Byrons ODCM computer program RETDAS in units of pCi/cc.

f.2 Liquid Releases As described in the UFSAR Section 1 1 .2, Revision 9, December 2002, liquid effluent is released into the discharge canal and offsite dose due to liquid releases are based on isotopic concentrations in the discharge canal with dilution, if any, as described in Attachment R. The volumetric dilution rate is 13000 gpm on a per unit basis as defined in UFSAR Section 11.3.3.4, Revision 9 December2002 and provided in Calculation lnput2.15. The units of release into the discharge canal in UFSAR Table I I .2-i of the Byron UFSAR, Revision i2, December 2008 are Ci/yr. As described in Attachment A, the desired units of input into RETDAS are pCi/mI.

• Based on Table I I .2-1 of the UFSAR, Revision 12, December 2008 Based on ODCM CY-BY-170-301, Revision 12, Table 2-4 The documentation does provide justification for the removal of Ba-I 37m from the ODCM.

Comparing the discharge concentrations between the ODCM Table 2-4 and those based on UFSAR Table I I , Revision I 2, December 2008 shows that they are the same, accounting for the variation due to rounding between the two documents. Since the Braidwood analysis used the annual airborne releases, and only the airborne releases, from the UFSAR in their calculation, the Byron analysis will use the airborne and liquid releases based on tables in the UFSAR.

The airborne releases to the environment and the liquid releases to the environment, Table

7. I -I and Table 7.2-I respectively, were transmitted to the Byron Station via Sargent & Lundy E-Mail as input to their ODCM computer code RETDAS. As part of the calculation review process, nuclides in Table 7.1-I and Table 7.2-I were compared to the respective inputs of RETDAS, where applicable, and found to be acceptable, confirming the use of the same airborne and liquid source terms.

SUMMARY

10.1 IOCFR5O Appendix I As shown in Tables 9.1-1, 9.1-2, 9.1-3 and 9.1-4, the design objectives dose limitations in IOCFR5O Appendix I for gaseous releases are satisfied for both cases, filtered and unfiltered, as calculated based on the source terms in UFSAR Table 11 .3-7, UFSAR, Revision 5, 1994.

Yearly doses are well below the criteria in IOCFR5O Appendix I. The only dose affected by the operation of the OGFU is that to the thyroid. Thyroid doses at the Unrestricted Boundary increase by 48% (9.82/6.64) when iodine releases are adjusted for the removal of the OGFU.

Since the OGFU charcoal filter units are currently not functional, there will be no actual change in dose due to primary to secondary leakage. In addition, the NRC did not credit the operation of the OGFU in their calculations of offsite dose. Therefore, the permanent bypass of the OGFU will not result in an increase in dose to the general public as calculated by the NRC in support of Byron Stations license application.

The liquid releases are not changed by this modification. Therefore, dose consequences associated with the liquid releases are unchanged. Results tabulated in Table 9.2-1 and Table 9.2-2 demonstrate compliance with Appendix I liquid release dose limits in ODCM Table 1 -1.

The ODCM currently considers the OGFU a mechanism in the Ventilation Exhaust Treatment System to reduce the release of radioactivity. Since the requirements of ODCM Section 4.1.5 and Technical Specification 5.5.4 are operational limitations, it is acceptable to assume that operator actions can be taken to limit the release of radioactivity to the environment via the Off-Gas Treatment System in the event of primary to secondary leakage.

10.2 IOCFR2O Compliance Per guidance tabulated in Table I -1 the Regulatory Dose Limit Matrix of the ODCM (CY-BY 170-301), Revision 12, compliance to IOCFR2O.1301 (a) (1) is demonstrated by complying with 4OCFR19O. See Attachment N.

Compliance with the IOCFR2O instantaneous annual dose requirements of ODCM Table 1-1 is demonstrated in Table 9.3-1 and Table 9.3-2 of this calculation.

10.3 IOCFR2O Appendix B Airborne Concentrations:

As indicated in Table 9.1-5 and Table 9.1-6, airborne concentrations for 1-131 and 1-133 are significantly below the criteria in I OCFR2O Appendix B, though the maximum unfiltered increase in iodine concentration is approximately 48% (1-131) and 60% (1-133).

10.4 4OCFRI9O Compliance Based on the discussion in Section 2.13, there are no direct shine contributions from contained sources on the Byron site. The direct shine contribution to the 4OCFR19O compliance summation is zero. As observed in Table 9.5-1 and Table 9.5-2, the total annual dose of the three organs of interest are less than those specified in the ODCM Regulatory Dose Matrix, Attachment N regardless of the configuration of the OGFU.

11.0 CONCLUSION

S I I I The predicted increase in the release of radioactive materials is insignificant as a result of the permanent bypass of the OGFU. Based on information tabulated in Table 9. 1 -5 and Table 9. 1 -6 the following tables are constructed for comparison purposes of filtered and unfiltered iodine concentrations at the restricted and unrestricted area boundaries:

I I .2 The predicted increase in occupational doses to plant personnel at the restricted area boundary and doses to the general public at the unrestricted area boundary are insignificant as a result of the permanent bypass of the OGFU based on the insignificant concentrations of I-131 and 1-133 atthe restricted and unrestricted area boundaries.

I I .3 Liquid releases and associated doses are not changed due to bypassing of the OGFU.

I I .4 Items I I .1 and I I .2 above assume that the OGFU is functional, however, the charcoal units are currently not in use and their iodine removal capability is not confirmed. Therefore, the permanent bypassing of the OGFU does not result in an increase in radioactive materials or dose to the general public.

I I .5 The off site airborne effluent doses, as calculated by the NRC in support of Byrons Stations license application, are not increased as a result of permanent bypassing of the OGFU.

[ NO. BYR16-012 REVISION: 0 Page 40 of 40 I I .6 Appendix I compliance for filtered and unfiltered airborne releases is tabulated in Tables 9.1-1 through 9.1-4.

Therefore, this calculation justifies the permanent bypassing of the OGFU under EC 402667, Rev. 1.

Jeff, Based on the information provided in the Byron ODCM, Table 1-1 Regulatory Dose Limit Matrix and Table 1-b, Compliance Matrix:

1 Appendix I compliance has an Airborne Release and a Liquid Release dose component for comparison purposes.

These components are NOT summed for this comparison. The Airborne Release and the Liquid Release components of the dose have their respective regulatory limits for each comparison Note that theseare organ doses in terms of mrad and mrem.

2. IOCFR2O compliance has an Airborne Release and a Liquid Release dose component for comparison purposes.

These dose components are summed for this comparison. Note that this is Total Effective Dose Equivalent in terms of mrem TEDE.

3. 4OCFRI9O compliance has an Airborne Release, a Liquid Release and a direct dose component from contained sources on the plant site for comparison purposes.

The dose associated with the Airborne Release, the total dose associated with the Liquid Release and the direct dose from the contained plant sources are summed for comparison. Additionally, the organ doses to an adult due to all pathways are required.

4. For the direct dose from the on site contained sources, a term of the 4OCFRI 90 summation, we are assuming that there is a standard, but conservative, value in RETDAS that is combined with the dose results of the airborne and liquid releases, yielding the total for comparison against the regulatory limits.

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE 2B of 23B B/B-UFSAR 11.2 LIQUID WASTE MANAGEMENT SYSTEMS In general, the liquid radwaste system collects, monitors, and recycles or releases, with or without treatment where appropriate, all potentially radioactive liquid wastes produced by the station during normal operation and maintenance, as well as transient conditions. The only exception is that effluent from the treated water system (Byron only) , the condensate polisher sump and the turbine building fire and oil sump, because of minimal activity levels, is normally discharged without being processed through the liquid radwaste system. Effluent from these sumps is monitored by radiation monitors that will automatically terminate sump discharge if unacceptable activity is present in the sump effluent. Corrective action can then be initiated to reroute the sump effluents to the appropriate treatment system prior to release.

11.2.1 Design Bases 11.2.1.1 Safety Design Basis The liquid radwaste system is designed so that liquid radwaste discharged from the site will have radioactive nuclide concentrations well within the limits specified in 10 CFR 20 and 10 CFR 50, Appendix I.

Each liquid radwaste processing stream terminates in a monitor tank (see Drawing M-48A) . Since the liquid radwaste system operates on a batch basis, this arrangement allows each treated batch to be sampled to assure that the treatment was sufficient.

If the sample indicates that the waste needs further processing, it is recycled either through the same subsystem or through another subsystem providing a different form of treatment. If the treated waste water is not needed for reuse, the water is sent to either release tank (OWXO1T or OWX26T) for discharge.

Each batch is sampled prior to discharge from the release tank to verify that its activity level is within limits for discharge.

The actual discharge to the circulating water blowdown line requires manually opening a remotely operated valve with a keylocked switch. The key for the valve lock is controlled by administrative procedures.

11.2.1.2 Power Generation Design Basis The liquid radwaste system is sized to handle maximum expected liquid waste inputs on the basis of both volume and activity as a result of normal operation, including anticipated abnormal occurrences for Units 1 and 2.

The liquid radwaste system is composed of the following two subsystems:

a. the steam generator blowdown subsystem, and

b. the nonblowdown radwaste subsystem.

11.2-1 REVISION 9 - DECEMBER 2002

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 3B of 23B B/B-UFSAR These subsystems are extensively crosstied to provide a high degree of availability and reliability.

The purpose of the steam generator blowdown subsystem is to maintain the steam generator water chemistry within specified limits.

The liquid radwaste system is designed to permit recycling of plant water. The stations are designed to minimize noncontaminated inputs from leakage of service water, circulating water, and groundwater into the plant floor drain system.

A cost-benefit analysis is not required for the liquid radwaste system. This is because Commonwealth Edison has complied with the Guides on Design Objectives for Light-Water-Cooled Nuclear Power Reactors proposed in the concluding statement of the position of the regulatory staff in Docket RM-50-2 dated February 20, 1974, pp. 2530.

11.2.1.3 Expected Radioactive Releases Byron and Braidwood Nuclear stations have updated the core power level twice. First to a core power level of 3586.6 MWt, then to the Measurement Uncertainty Recapture uprate power level of 3645 MWt. The original licensed power level was 3411 MWt. The original expected liquid radwaste effluent data presented in the UFSAR is based on a power level of 3565 MWt.

Expected annual average releases of radionuclides from the liquid radwaste system are shown in Table 11.21. These releases were determined by using the NUREG 0017/PWR-GALE computer program (References 1 and 2) . Both the original as well as the uprated parameters describing the expected normal operation of one unit of the station are listed in Table 11.22. These values were used as input to the computer code for the original analyses.

The impact of core uprate on the effluent releases was evaluated based on an assessment of the changes in input parameters.

Core uprate results in a maximum potential increase of 0.6% in the liquid effluent release concentrations previously reported.

Taking into consideration the accuracy and error bounds of the operational data utilized in NUREG 00017, this small percentage change is well within the uncertainty of the calculated results of the original NUREG 0017 based expected liquid effluent concentrations presented in Table 11.24 which remain valid for uprate.

For tables 11.2-1 and 11.2-4 (for Braidwood only), actual data has been used to determine the expected tritiuin (H-3) release and blowdown concentration values.

As can be seen from the total dose rates from the various exposure pathways, the numerical guidelines set forth in Appendix I to 10 CER 50 are satisfied. As discussed in Section 11.2.1.3, this assessment and Table 11.23 remain valid for uprate.

For Braidwood only, dose calculations using actual release data and compiled in annual effluent release reports, in accordance with the ODCM, indicate that normal liquid effluents, including tritium, are typically within the estimates of Table 11.2-3 and within guidelines of 10 CFR 50 App.I.

11.2.1.5 10 CFR 20 Comparison Table 11.2-4 compares expected liquid effluent concentrations with 10 CER 20 limits. It can be seen that the expected effluent concentrations are significantly below the specified limits. As discussed in Section 11.2.1.3, this assessment and Table 11.2-4 remain valid for uprate.

For Braidwood only, actual liquid effluent release data compiled in annual effluent release reports, in accordance with the ODCM, indicate that effluents are maintained within the concentration and dose guidelines of 10 CFR 20.

All components (including tanks, pumps, valves, and piping) of the liquid radwaste system containing radioactive wastes are classified as Quality Group D, with the exception of the containment penetration piping out to and including the second isolation valve from the containment sump pump discharge, which is Quality Group B piping and valves (refer to Section 3.2).

11.2.1.8 Facility and Equipment Design The liquid radwaste system is designed to minimize radiation exposure to operating personnel. Normal operations, maintenance, and nonroutine operations are discussed in the following.

11.2. 1. 8 1

. Maintenance Operations Wherever practicable, components of the liquid radwaste systems are segregated to the maximum extent practical. To reduce radiation exposure to maintenance personnel, components are arranged so that access to a low activity component does not necessitate passing near a high activity component. Instruments are located in low dose rate areas wherever practical to minimize the radiation exposure to maintenance personnel.

Valves, where practicable, are located outside of compartments to minimize radiation exposure from tanks or components during valve maintenance. Most radwaste pumps are equipped with mechanical seals to minimize maintenance.

In general, components which may require maintenance are capable of being flushed prior to maintenance.

11.2.1.8.2 Floor, Wall, and Ceiling Coatings In rooms containing radioactive wastes, the floors, and as necessary, the walls and ceilings, are coated with a two-coat water base epoxy paint for ease of decontamination.

11 2 1 9

. . . Tank Level Control Provisions are made to preclude uncontrolled spills due to tank overflows. The following criteria apply to tanks outside the containment building which may contain radioactive fluids:

a. Tank level instrumentation is provided on most radwaste tanks with readout devices in the radwaste control room. A high-level condition on these tanks will be annunciated.

b. Some radwaste tanks overflow to an adjacent sump, as described in Table 11.2-9. Sumps are provided with 11.2-3 REVISION 2 - DECEMBER 1990

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 6B of 23B B I B-UFSAR duplex or triplex (redundant) pumps as appropriate.

Sumps are level controlled and logic is provided to start and stop pumps automatically.

c. Provisions for tank level indication, level annunciation, and overflows are given in Table 11.29 for all tanks outside the containment building containing potentially radioactive liquids.

11.2.1.10 Prevention of Uncontrolled Releases Based on operating experience during normal operations, it is expected that it will be necessary to make controlled releases of contaminated steam and condensate leakage to the environment.

During normal operations, these releases of radioactive liquids to the environment are from the release tank after processing, as needed, by the liquid radwaste system.

As a batch of waste is processed, the effluent is transferred to an appropriate monitor tank (e.g., blowdown monitor tanks, boric acid monitor tanks, and radwaste monitor tanks) for sampling prior to being transferred to the release tanks or being reprocessed. In the release tanks, the liquid is mixed and sampled for activity prior to discharge. The release tanks discharge must pass through either one of two remotely controlled keylocked valves (0WX353 and 0WX896 on Drawing M-48-1) to be released from the station. Limit switches supply status information on the valve position to the operator at the radwaste control panel. A radiation monitor is provided to automatically close the valves on a high radiation signal.

In addition, effluents from the treated water system, the condensate polisher sump and the turbine building fire and oil sump are released to the environment. While normally considered non-radioactive, these effluents can potentially become contaminated, and the sump effluents are monitored by radiation monitors which will halt sump pump operation if unacceptable activity levels are present in sump effluent.

Branch Technical Position BTP 11-1, Revision 1, and meets the criteria of Regulatory Guide 1.143, as described in Appendix A.

11.2.2 System Description The liquid radwaste system is shared by both units. Unit 1 and Unit 2, however, have separate equipment and floor drain collection sump systems. Process flow diagrams are shown in Drawing M-48A. The systems are depicted in Drawings M-48-l through M-48-40.

Inputs to the system are separated according to origin and/or concentrations of radioactivity and chemical impurity. Separate collection tanks are provided for each input stream. The waste is routed from the collection tanks to the appropriate processing paths. The system processes the radioactive liquid waste by various combinations of filtration, evaporation (Braidwood only),

and/or demineralization. At Braidwood, vendor radwaste processing systems may utilize filtration, demineralization, chemical and ultraviolet treatment, and/or reverse osmosis to assist in radioactive liquid waste processing and recycling.

Provisions are made to bypass any processing device. The release tanks cannot be bypassed.

After being processed through the various equipment items, the purified effluent can be reused as secondary cycle makeup at Byron, primary cycle makeup at Braidwood, or released to the environment via the circulating water blowdown line.

11.2-5 REVISION 12 DECEMBER 2008

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 8B of 23B B/B-UFSAR The liquid radwaste system is designed to handle wastes generated during design-basis operational occurrences. This is accomplished by providing sufficient process capacity within the subsystems and collection and monitor tanks of adequate size.

The liquid radwaste system consists of two crosstied subsystems:

a. steam generator blowdown subsystem, and

b. non-blowdown radwaste subsystem which treats the following waste streams:

1. auxiliary building equipment drains,

2. auxiliary building floor drains,

3. chemical waste drains,

4. regeneration waste drains,

5. laundry (detergent) drains,

6. turbine building equipment and floor drains when contaminated, and

7. condensate polisher sump when unacceptably contaminated.

Expected concentrations of radioactive nuclides in the various input waste streams to the radwaste subsystems are listed in Table 11.1-6. Expected inventories of radioactive nuclides in major components of the liquid waste system are tabulated in Tables 11.1-7 through 11.1-12. Table 11.26 lists the annual average and maximum expected daily flows of each waste stream.

The expected activities in Table 11.1-1 correspond to the annual average daily flows. The activities for the maximum daily flows vary significantly. Actual release data are available in the effluent release reports, which are prepared in accordance with the ODCM.

Table 11.2-7 lists the design-basis decontamination factors for the processing components used in the analysis of the systems.

The original steam generator blowdown prefilters were replaced with larger prefilter units. However, the expected average and maximum waste stream flows and the design basis decontamination factors for the steam generator blowdown prefilters were not revised to account for the larger prefilter volume.

11.2.2.1 Steam Generator Blowdown Subsystem The function of the steam generator blowdown subsystem is to maintain steam generator shell side water chemistry within the 11.2-6 REVISION 7 - DECEMBER 1998

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 9B of 23B B / B-UFSAR specified limits. Continuous blowdown constantly removes impurities from the steam generator. The flow rate is varied as required to maintain the steam generator water chemistry within the required limits.

At Byron, steam generator blowdown may be sent to the condensate polisher sump to improve secondary chemistry when excessive impurities are present that would quickly exhaust steam generator lilowdown demineralizers.

For a further description of the steam generator blowdown subsystem, see Subsections 10.4.8 and 10.4.9.3.1.

11.2-Ca REVISION 6 - DECEMBER 1996

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE JOB of 23B B/B-UFSAR The components of the steam generator blowdown treatment subsystem include four blowdown prefilters; four blowdown mixed bed demineralizers; four blowdown demineralizer after filters; three blowdown monitor tanks; and associated pumps, valves, and instrumentation.

11.2.2.1.1 Normal Operation Steam generator blowdown is operated in a normal range of 15 to 90 gpm per steam generator, depending on steam generator chemistry requirements. During normal operation, blowdown is pumped from the steam generator blowdown condenser hotwells through the blowdown prefilters, the blowdown mixed-bed demineralizers, and the blowdown after filters to the condensate storage tanks or respective unit hotwell. In the event of high radioactive material in the purified effluent leaving the blowdown mixed-bed demineralizers, the effluent is diverted to the monitoring tanks. Unit 1 and Unit 2 blowdown is normally segregated, as the Unit 1 and Unit 2 condensate storage tanks are normally segregated.

Blowdown from each steam generator is sampled and analyzed at periodic intervals to determine:

a. If the blowdown flow rate requires adjustment to maintain the steam generator water chemistry limits.

b. If leakage condition exists, either at the main condenser or primary to secondary leakage within one or more steam generators so that remedial action can be taken.

c. If the method of processing the blowdown should be changed.

The time interval between samples of the blowdown from each steam generator depends upon operating experience.

The effluent from each blowdown mixed bed demineralizer is directed through a blowdown afterfilter to a header which is valved so that Unit 1 effluent is normally separated from Unit 2 effluent. Conductivity of each effluent stream from the blowdown mixed bed demineralizers is monitored. The processed liquid can be routed to either Unit 1 or Unit 2 condensate storage tanks as 11.2-7 REVISION 6 - DECEMBER 1996

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE lIE of 23B B/B-UFSAR described above or to a monitor tank. The water in the blowdown monitor tanks is normally drained to the turbine building floor drain system. The water may also be used to sluice blowdown demineralizers or to backwash blowdown demineralizer strainers.

In addition to processing steam generator blowdown, the blowdown mixed bed demineralizers can be used for processing turbine building equipment drains, turbine building floor drains, and for the further processing of the purified effluent from the radwaste subsystems via the radwaste and blowdown monitor tanks. This practice is not recommended for normal operation.

Effluent from the blowdown prefilters of each unit can be diverted to each of the three radwaste evaporators, but normally this flowpath is blocked by a spectacle blank flange (Braidwood only).

11.2.2.1.2 Circulating Water to Secondary System Leakage In the event of condenser tube or tube sheet leakage, the blowdown rate may be increased to 360 gpm (180,000 lbs/hr) total per unit to keep the steam generator shell side chemistry within operating limits. The blowdown rate from the four steam generators would be approximately 90 gpm for each steam generator.

11.2.2. 1.3 Primary-to-Secondary-Leakage Concurrent with Failed Fuel The radioisotope concentration in the steam generator blowdown is given in Table 12.2-30 and Table 11.1-6. If primary to secondary leakage occurs in only one steam generator, the blowdown rate from nonleaking steam generators remains high enough to maintain chemistry specifications while the blowdown rate from the leaking steam generator may be increased to the design rate of 90 gpm.

11.2.2.1.4 Primary-to-Secondary Leakage Not Concurrent with Failed Fuel The steam generator blowdown during primary-to-secondary leakage not concurrent with failed fuel will be processed as discussed in Subsection 11.2 .2. 1.3 during transient operating conditions.

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE 12B of 23B B /B-UFSAR 11.2.2. 1. 5 Transient Operating Conditions Increased blowdown may be used to keep the steam generator water chemistry within specifications.

11.2.2.2 Nonbiowdown Liquid Radwaste Subsystem This processing train collects and treats liquid radwastes from sources other than steam generator blowdown. The mode of operation is batchwise. The nonblowdown liquid radwaste subsystem includes the following input sources:

a. auxiliary building equipment drain,

b. auxiliary building floor drain,

c. chemical waste drain,

d. regeneration waste drain,

e. laundry (detergent) drain,

f. turbine building equipment and floor drain (when contaminated),

g. turbine building fire and oil sump (when contaminated)

(Byron only),

h. condensate polisher sump when unacceptably contaminated, and

i. waste treatment system (when contaminated) (Byron only).

Each drain system except the chemical waste, regeneration waste, and laundry drains, has two drain collection tanks. The chemical waste and regeneration waste drains utilize one tank each plus a shared dual purpose chemical/regeneration waste drain tank.

Waste is usually collected in one of two drain tanks. The contents of the other tank may be sampled or processed. The sample is taken from the recirculation line. Chemical additions to adjust the wastewater pH or filter aids may be added to improve waste processing efficiency.

Oil separators are provided in those suinps that could potentially have oil in the water. A filter is installed downstream of each drain tank pump discharge header, or drain tank effluent is sent to vendor-installed equipment for filtration as needed.

11.2-9 REVISION 10 - DECEMBER 2004

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 13B of 23B B/B-UFSAR The radwaste evaporator inlet header receives liquid wastes from the previously mentioned drain tanks. The liquid wastes entering the radwaste evaporator inlet header normally bypass the evaporators and are processed by the radwaste demineralizers or by the vendor demineralizers.

At Byron, nonessential service water to the radwaste evaporator skids has been isolated permanently. Blank plates have also been installed in the inlets to the evaporators to prevent liquid wastes from entering.

The radwaste monitor tanks collect radwaste demineralizer effluent. The tanks contents will be mixed and sampled prior to being transferred to the release tank.

Wastewater may be routed from the radwaste monitor tanks to vendor taps in the radwaste building for additional processing, as needed, and returned to the installed radwaste system for monitored discharge.

Based on this sample and station water balance considerations, the water may be reprocessed or discharged via the release tanks.

See Table 11.2-6 for the designbasis average and maximum waste stream flows for the various inputs that are discussed in the following. Also refer to Table 11.1-6 for the realistic source terms for these inputs.

At Byron, effluent from the condensate polisher sump, from the turbine building floor and equipment drains (collected in the turbine building fire and oil sump) and from the waste treatment system is processed by the radwaste system if the contamination exceeds effluent limits for the sumps. The sump effluent is monitored by radiation monitors to ensure that ODCM limits are maintained.

At Braidwood, effluent from the condensate polisher sump and from the turbine building floor and equipment drains is processed by the radwaste system if contamination levels exceed effluent limits. The turbine building fire and oil sump effluent is monitored by a radiation monitor to ensure that ODCM limits are maintained.

At Braidwood, a Radwaste Storage Tank (RST) is used to store and manage the release of radioactive liquid waste containing elevated concentrations of tritium. Based on waste water tritiuin concentration, influenced by the time period of the fuel cycle of each unit, discharge of the waste water may be delayed and the waste water stored in the RST. The tanks contents are sampled to determine the degree of processing required prior to transferring the contents to the liquid radwaste release tanks for discharge.

Input sources to the auxiliary building floor drain tanks include the following:

a. reactor cavity suiaps,

b. containment floor drain sumps,

c. auxiliary building floor drain suinps,

d. fuel handling building floor drain sumps, and

d. drumming station sumps,

e. boric acid processing system,

f. primary water storage tank, and

g. any other high-conductivity radioactive drains.

One tank is provided solely for the chemical drains. A second tank is used as a dual purpose chemical/regeneration waste drain tank. These wastes are processed through a demineralizer.

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE 16B of 23B B/B-UFSAR 11.2.2.2.4 Regeneration Waste Drain Input sources to the regeneration waste drain tank and the dual purpose chemical/regeneration waste drain tank include the following:

a. spent resin sluicing drain header,

b. drumming station decanting tank overflows (Byron only),

c. release tanks (regeneration waste drain tank only),

and

d. tendon tunnel suxnps (when determined to be a source of radiation contamination into the fire and oil sump).

The blowdown and radwaste mixed bed demineralizers are replaced as often as is required to maintain the demineralizers effluent water quality.

11.2.2.2.5 Laundry Drain The laundry drain tank collects detergent wastes from the radioactive laundry (Braidwood only) , personnel decontamination shower and the TSC drains and showers. These waste streams are sent to the release tanks for release or a radwaste demineralizer for further treatment.

11.2.2.2.6 Turbine Building Equipment Drain Secondary system drains are divided into turbine building equipment drain and turbine building floor drain. The turbine building equipment drain system can recover a large amount of condensate grade water for station reuse.

Two turbine building equipment drain tanks receive water from the turbine building equipment drain suinps. Since this drain water is from the secondary system, the water in the turbine building equipment drains are normally uncontaminated or only very slightly contaminated. The water is normally treated in the wastewater treatment plant for discharge. There are also flowpaths from the turbine building equipment drain system to the radwaste demineralizers and to the liquid release tank.

11.2-12 REVISION 10 - DECEMBER 2004

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 17B of 23B B/B-UFSAR At Byron, in the event of excessive leakage of the primary coolant into the secondary system, the water may be processed in the waste treatment plant and returned to the release tank for discharge. At Braidwood, in the event of excessive leakage of the primary coolant into the secondary system, the contaminated water may be processed through the coalescer/carbon filters and through additional filtration as needed and discharged via the release tanks, but normally this flowpath is blocked by a spectacle blank flange.

11.2.2.2.7 Turbine Building Floor Drain The two turbine building floor drain tanks collect water from the turbine building floor drain sumps, condensate pit sumps, and essential service water sumps. These wastes are normally nonradioactive, except for tritium, and are released to the environment after filtration via the wastewater treatment (TR) system.

11.2.2.2.8 Turbine Building Fire and Oil Sump Turbine building waste water collected in the fire and oil sump, including equipment and floor drain water, is monitored by a radiation monitor. Water from this sump is normally discharged to the waste treatment system for removal of oil and solids and then released to the environment via the circulating water system and blowdown line. However, if unacceptable radioactive contamination is detected, the sump pumps are automatically stopped and the water may be sent to the liquid radwaste treatment system, via the waste treatment system (Byron only)

If the source of radioactive contamination is determined to be one of the tendon tunnel sumps, either tendon tunnel pump discharge can be sent to the regeneration waste drain tank for processing in the radwaste system. The water may be processed by the waste treatment plant and returned to the release tanks for discharge (Byron only).

11 2 2 2 9

. . . . Condensate Polisher Sump Water in the condensate polisher sump is monitored by a radiation monitor on the sump discharge. Water from this sump discharge is normally directed to the circulating water system, and then released to the environment via the blowdown line. If a high radiation signal is detected, pump operation is automatically stopped and major condensate polisher inputs into the sump are automatically isolated. If samples confirm that the water is contaminated, the operator may manually change the valve lineup to send the water to the release tank for a monitored discharge.

11.2.2.2.10 WasteTreatment System The input to the waste treatment system is the Turbine Building Fire and Oil Sump (see 11.2.2.2.8) . Water processed by the waste treatment system is normally released to the environment via 11.2-13 REVISION 12 - DECEMBER 2008

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 18B of 23B B/B-UFSAR the circulating water system and blowdown line. If the radiation monitor on the Turbine Building Fire and Oil Sump should fail, an alarm will be annunciated in the radwaste control room, and the contents of the treated water system would be sampled. If the sample contains radioactive contamination, the systems contents would be pumped to the liquid radwaste system.

11.2-13a REVISION 6 - DECEMBER 1996

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE 19B of 23B B/B-UFSAR 11.2.2.3 Operating Procedures If the contents of a monitor tank are to be released, the required radioactivity analysis is performed prior to transferring the material to the release tank. The liquid is then pumped to a release tank where a sample is again taken and the required analysis is performed. Based on this analysis, the discharge rate is determined so that, when mixed with cooling water blowdown discharges, the water leaving the plant has a radioactivity level less than the applicable effluent concentration as stated in the Technical Specifications. A remotely operated valve with a keylocked switch may then be manually opened so that water can be discharged. The key for the valve lock is controlled by administrative procedures. As a further backup, a radiation detector monitors the liquid in the discharge line prior to the point where the liquid is mixed with the cooling water blowdown to the river. Upon detecting an abnormal level of radiation, a valve on the release tank line immediately upstream of the mixing point closes and an alarm signal is relayed to the control room. A composite sample of the cooling water blowdown is analyzed to verify that radioactive releases conform with the requirements of the Technical Specifications. Records are maintained of radioactive wastes discharged to the environment.

11.2.2.4 Performance Tests Liquid wastes may be monitored before and after each processing step on a batch basis. The equipment is therefore subjected to continuous performance testing.

Data on specific isotope decontamination factors are not conclusive. This system was designed using conservative overall decontamination factors. These decontamination factors are based on guidelines from References 2, 4, and 5.

Through system cross-ties, redundancy of equipment, and excess storage capacity, ample provision has been made for equipment maintenance and for reprocessing treated effluents if required.

11.2.2.5 Control and Instrumentation A large portion of the liquid radwaste system is controlled and monitored from the liquid radwaste control panel (LRCP) located in the radwaste control room. Radwaste and blowdown demineralizers and radwaste evaporator control panels and the liquid/solid radwaste interface are also located in the radwaste control room. The solid radwaste handling system control panel is located in the radwaste building.

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 21B of 23B BYRON-UFSAR 11.2.3 Radioactive Releases 11.2.3.1 Release Points All liquid radwaste system effluent paths for radioactive nuclides to the environment are suitably processed, monitored, and recycled or discharged via the release tanks in accordance with procedures outlined in Subsection 11.2.2.3. The radioactive waste release line joins the circulating water blowdown line.

Water from the turbine building fire and oil sump, the condensate polisher sump and the treated water system (Subsections 11.2.2.2.8, 11.2.2.2.9 andll.2.2.2.lO), if not unacceptably contaminated, is discharged after suitable treatment into the circulating water flume, and released via the blowdown line.

11.2.3.2 Dilution Factors At 100% capacity factor and design-basis ambient air conditions, blowdown from the circulating water system serving the two units is approximately 23,000 gpm. On an average annual basis, the circulating water blowdown is expected to be approximately 13,000 gpm, or 2.6 x 1013 cm3 per year. The annual radionuclide release and the concentration in the cooling tower blowdown line are given in Table 11.2-4.

Circulating water blowdown enters the Rock River approximately 50 yards downstream of the intake structure, so releases do not become entrained in makeup water. The circulating water blowdown warming line to the river screen house is isolated during releases to prevent entraining radionuclides in the circulating water and essential service water makeup lines.

11.2.3.3 Estimated Annual Average Doses The estimated total annual release of radionuclides in liquid effluents is given in Table 11.2-1. Using an annual dilution volume of 2.6x103 cm3, the concentration of each nuclide in the cooling tower blowdown line can be determined. This is shown in Table 11.2-4.

Estimated annual average doses to individuals exposed to radioactive liquid effluents were calculated using the methodology of Regulatory Guide 1.109 (Reference 3) . Fish consumption, drinking water, and recreational exposure pathways were considered. Annual use factors for these pathways are given in Table 11.2-8.

In order to obtain a conservative estimate of the radiation doses, no radioactive decay or dilution by river water was taken into consideration.

Estimates of doses to the whole body and to different organs are summarized in Table 11.2-3. As explained in Subsection 11.2.1.4, these estimated doses are all within Appendix I to 10 CFR 50 guidelines. Actual release data are available in the effluent release reports, which are prepared in accordance with the ODCM.

ANALYSIS NO. BYRJ6-012 BRk-FSAR PAGE 22B of 23B 11.2.3 Radioactive Releases 11.2.3.1 Release Points All controlled liquid radwaste system effluent releases of radioactive nuclides to the environment are suitably processed, monitored, and recycled or discharged via the release tanks in accordance with procedures outlined in Subsection 11.2.2.3. The radioactive waste release line joins the cooling pond blowdown line as indicated in Drawing M-48-l. Water from the fire and oil sump, and condensate polisher sump (Subsections 11.2.2.2.8 and 11.2.2.2.9), if not unacceptably contaminated, is discharged, after suitable treatment, into the cooling pond at the circulating water discharge canal, where it mixes with circulating water prior to release via the blowdown line.

Temporary groundwater remediation activities, where contaminated water from the Exelon Pond and surrounding groundwater is pumped into the circulating water blowdown line at Vacuum Breakers 1 and 2, contribute to the inventory of radioactive nuclides released to the environment via the blowdown line. Periodic sampling of the water is used to monitor the radioactivity of the water that is discharged into the blowdown line.

11.2.3.2 Dilution Factors At 100% capacity factor, blowdown from the cooling lake is expected to be 25,000 gpm on an annual average basis, or 4.98 x 1013 cm3 per year. The annual radionuclide release and the concentration in the cooling pond blowdown line are given in Table 11.2-4. Blowdown isotope concentrations were calculated using cooling pond blowdown flow of 12,000 gpm, which is the normally expected blowdown flow rate without the use of blowdown booster pumps.

Cooling pond blowdown enters the Kankakee River approximately 50 yards downstream of the intake structure, so that releases do not become entrained in makeup water.

11.2.3.3 Estimated Annual Average Doses The estimated total annual release of radionuclides in liquid effluents is given in Table 11.2-1. Using an annual dilution volume of 2.4 x iO cm3, the concentration of each nuclide in the discharge canal can be determined. This is shown in Table 11.2-4.

Estimated annual average doses to individuals exposed to radioactive liquid effluents were calculated using the methodology of Regulatory Guide 1.109 (Reference 3) . Fish consumption, drinking water, and recreational exposure pathways were considered. Annual use factors for these pathways are given in Table 11.2-8.

In order to obtain a conservative estimate of the radiation doses, no radioactive decay or dilution by river water was taken into consideration.

Estimates of doses to the whole body and to different organs are submitted in Table 11.23. As explained in Subsection 11.2.1.4, these estimated doses are all within Appendix I to 10 CFR 50 guidelines. Actual release data are available in the effluent release reports, which are prepared in accordance with the ODCM.

Attached are the dose reports that have been reviewed by my supervisor (Z. Cox). I only ran annual dose reports because the Appendix I annual dose limits are twice the quarterly limits. Since we are using average effluent concentrations, once we demonstrate compliance to annual limits we automatically demonstrate compliance to quarterly limits. RETDAS is very temperamental, so when you look at the reports, ignore the listed monthly and quarterly limits and focus only on the annual limits. The gaseous and liquid annual reports demonstrate 10CFR5O Appendix I (per unit) compliance, the 4OCFR19O report demonstrates 4OCFRI9O (site) compliance, and the gaseous instantaneous report demonstrates 10CFR2O (site) compliance. Give me a call tomorrow and we can discuss them.

RE: [EXTERNAL] Byron Liquid Releases and Airborne Releases- per Unit or per Station Jeff, Thank you for the Clarification and correction. As far as doubling the annual release of UFSAR Table I 1 .2-1 is concerned, I am going to do some preliminary number crunching this evening with the gpm annual average dilution value in the UFSAR and compare some examples with ODCM Table 2-4, Assumed Composition of the Byron Station Liquid Effluent, which is in units of uCi/mI. I will E-mail you tomorrow.

RE: [EXTERNAL] Byron Liquid Releases and Airborne Releases- per Unit or per Station Barry, think there may have been a misunderstanding. I dont believe we concluded the liquid effluent concentrations listed in the UFSAR were on a station basis. But believe that I stated the liquid effluent concentrations (uCi/mi) needed to be listed on a station basis because that is the way they are required to be input to REIDAS. When a liquid release permit is created, it is a single permit. REIDAS subsequently allocates the curies and dose evenly between units.

So it sounds like the values in Table 11.2-1 just need to be doubled.

[EXTERNALJ Byron Liquid Releases and Airborne Releases- per Unit or per Station Jeff In our conference call of 7/14/2016 we discussed UFSAR Table 11.2-1 for expected annual liquid releases into the discharge canal. UFSAR Table I I .3-6 is the expected annual airborne release per unit as indicated by the double asterisk in the table title. The point of this discussion was UFSAR Table I I .2-1 an expected annual release to discharge canal per unit or per station. Since UFSAR Table I I .3-6 is explicitly annual release per unit, we concluded that UFSAR Table I I .2-1 is per station due to the absence of the per unit designation.

However, during the preparation of the draft calculation I was preparing a section of the calculation on the power uprate impact on normal operation source terms, airborne and liquid, UFSAR Section 1 1 .3.3.4 and UFSAR Table I I .3-7 and UFSAR Section 1 1 .2. 1 .3 and UFSAR Table I 1 .2-4, respectively.

The following tables are extracted directly from the UFSAR for comparison purposes:

LIQUID RELEASES Comparing the Total column of Table I I .2-1 with the Expected Release column of Table I I .2-4 shows that they tabulate the same annual releases, accounting for rounding. Note the units of release in the two tables, Ci/yr in Table I I .2-1 and Ci/yr/unit in Table 1 1 .2-4. The conclusion previously drawn on liquid releases being on a station basis was not correct. Based on Table I 1 .2-4, the units of release are Ci/yr/unit not Ci/yr/station.

AIRBORNE RELEASES Note the double asterisk in the title of Table I 1 .3-6 indicating that the table is on a per unit basis. In Table I 1.3-7, the 2nd column is entitled Annual Release From One Unitt. Therefore, these two tables explicitly indicate the annual releases are on a per unit basis.

In summary, liquid releases and airborne releases are in terms of Ci.yr/unit in Chapter 1 1 of the UFSAR.

New PDFs for liquid releases are in preparation and are being reviewed..

[EXTERNAL] Ew: B/B UFSAR/ODCM STATUS AS A DESIGN REFERENCE-DRAFT Ed, Is it possible to get Exelons concurrence to use UFSAR and ODCM info without a TODI? (Email from a Design Manager etc.)

We will not be able to locate the source document for the values in these documents.

I understand that the UFSAR is not a Design Basis Document and the ODCM is probably in the same category. However, it is the only document available to reference in the Caic.

The Radiological Department at S&L has some previous EXELON experience that did not allow them to use the UFSAR without a TODI and they have some reservations.

If such concurrence from EXELON is inconvenient to obtain, S&L will ghost-prepare the TODI and send it for EXELON to issue so we can attach to the Caic.

Please let me know.

Re: BIB UFSAR/ODCM STATUS AS A DESIGN REFERENCE-DRAFT

Barry, From CC-AA-310 CC-AA-3 1 0 describes the requirements to prepare a Transmittal of Design Information (TODI) for those cases when a controlled record is necessary. This is typically required when design hiformation is transmitted between the corporate office, sites, and vendors (e.g. manufacturer, Engineer of Choice (EOC)).

Transmittal of Design Information can be from the vendor to Exelon or from Exelon to the vendor. A TODI is available for use by anyone where the rigor of the process can be leveraged to ensure that precise design requirements are communicated.

The design information is not created or revised by this procedure An individual who has knowledge of the design information being transmitted, and the intended use of the design information by the recipient prepares the TODI in order that the recipient can appropriately use the information.

Processes that share critical information between the corporate office, sites, and vendors require the use of the TODI unless such information can be obtainedfrom documented and controlledplantfttes not requiringfurther interpretation These processes are the configuration change process and troubleshooting process.

In my opinion, (also discussed with Ed Englert) a TODI is not required in our case. The UFSAR is a controlled document and I am assuming that the extracted information requires no interpretation or direction on how to be used.

Therefore, the UFSAR data may be used by reference to the latest UFSAR Revision. If we feel further enhancement is necessary, we could make the specific UFSAR pages an attachment to the calculation. If my assumption is incorrect an guidance is needed, then we should proceed with the preparation of the TODI and have Byron sign it.

B/B UFSARIODCM STATUS AS A DESIGN REFERENCE-DRAFT John Over the years, the position on using the Commonwealth Edison/Exelon UFSAR as a design input reference for use in design calculations has changed several times from no to yes and back. The current point in question is Byron Calculation BYRI6-012 which analyzes the dose consequences of removing the steam jet air ejector process stream from filtration by the Offgas Filter Unit and releasing it to the environment via the station vent stack. Expected airborne releases (per unit) and expected liquid releases (per station) are tabulated in UFSAR Table I I .3-6 and UFSAR Table I I 1 respectively. These tables are the output of NUREG-OO1 7 ( the PWR GALE Computer program). UFSAR Table 1 1 .2-2 contains some PWR GALE input parameters and UFSAR Sections 1 1 .2 and I I .3 contain supporting text and other parameters.

Attempts to resurrect the PWR GALE computer runs and any associated calculation write-ups proved futile. The text and data from UFSAR Chapter 1 1 now become the primary reference for Calculation BYRI6-012 and the Byron ODCM computer program RETDAS, which generates the dose consequences and documents the regulatory comparisons. In a similar analysis for Clinton, Exleon provided UFSAR text, data and associated documentation with directives on how to use the information attached to a TODI. The TODI then became an attachment to the Clinton calculation.

Please clarify Exelons position on the use of the UFSAR as a primary reference for Byron design calculations. For added flexibility, please do the same for the ODCM.

3. Average Energy: This item is not applicable. The ODCM limits the dose equivalent rates due to the release of noble gases to less than or equal to 500 mrem/year to the total body and less than or equal to 3000 mrem/year to the skin.

4. Measurements and Approximations of Total Radioactivity

a. Fission and activation products: Prior to release, the isotopic content is determined. Released activity is calculated using volume of release, which is determined by the change in tank level, containment pressure, or containment purge fan flow rates.

b. Particulate and iodine sampling media for the plant vent stacks are continuously collected and analyzed weekly. Tritium and noble gas analysis for the plant vent stacks are obtained and analyzed weekly.

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 40 of 800 C. Liquid effluents: Isotopic analysis is performed on each batch liquid release tank prior to its release. Total release activity is calculated using volume of release. Total tritium activity released is calculated from the highest of a monthly circulating water blowdown composite activity or a sum of the effluent input composite activities.

d. All positive results (i.e. higher than the lower limit of detection (LLD)) are reported in units of uCi/cc or uCi/mI unless otherwise noted. All LLD values and the associated LLD requirements are listed in Attachment A.

8. Errata No errata data to report.

9. 2015 Radiological Groundwater Protection Program (RGPP) Results Summary:

In 2015, fifteen (15) Radiological Groundwater Protection Program (RGPP) monitoring wells were sampled in total. Groundwater samples were obtained in March, May, August, and November and analyzed for tritium. In addition, a study of gamma, gross beta, and gross alpha radioisotopes was performed in accordance with Nuclear Energy Institute (NEI) 07-07, Groundwater Protection Initiative, for the samples obtained in May. None of the May samples showed concentrations of radionuclides above what is considered background levels. Three wells contained levels of tritium above the lower limit of detection (LLD) of 200 pCi/L. They were: AR-4 (493 pCi/L in March, 723 pCi/L in May, 417 Page 3 of 79

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 60 of 800 A total of 8.05E-i-01 curies of tritium were released with a maximum average quarterly release rate of 3.99E+00 pCi/sec.

Gross alpha-emitting radionuclides were below detectable limits.

Liquids Released to Rock River Atotal of2.86E+J0 liters of radioactive liquid wastes containing 8.48E-03 curies offission and activation products were discharged with a maximum quarterly average concentration of 4.71 E-10 pCi/mi.

A total of 3.32E+03 curies of tritium were discharged with a maximum quarterly average concentration of I .56E-04 uCi/ml.

A total of 5.08E-04 curies of dissolved and entrained gases were discharged with a maximum quarterly average concentration of 5.56E-1 1 uCi/mi.

Gross alpha-emitting radionuclides were below detectable limits.

DOSE TO MAN GASEOUS EFFLUENT PATHWAYS Noble Gas Gamma Dose Rates Offsite Gamma air and whole body dose rates for the period were calculated based on measured release rates, isotopic composition of the noble gases, and average meteorological data. The maximum gamma air dose was 1 .76E-02 mrad based on measured effluents and average meteorological data, and 3.19E-03 mrad based on measured effluents and concurrent meteorological data.

Noble Gas Beta Air and Skin Dose Rates The range of beta particles in air is relatively small (on the order of a few meters or less).

Consequently, plumes of gaseous effluents may be considered semi-infinite for the purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive skin tissues is difficult to calculate due to the effect of the beta particle energies, thickness of inert skin, and clothing covering sensitive tissues. For purposes of this report the skin is taken to have a thickness of 7.0 mg/cm2 and an occupancy factor of I .0 is used. The maximum skin dose was 2.84E-04 mrem based on measured effluents and average meteorological data, and 2.97E-03 mrem based on measured effluents and concurrent meteorological data.

The maximum offsite beta air dose for the year based on measured effluents and average meteorological data was 8.55E-04 mrad, and 6.29E-04 mrad based on measured effluents and concurrent meteorological data.

Radioactive Iodine & Particulate The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. 1-13 1 released during routine operation of the station may be made available to man resulting in dose to the thyroid. C-14 is also included in this category. C-14 exhibits a capacity to concentrate in bone. C-14 is released in gaseous form and is absorbed into vegetation through photosynthesis. The principal pathways of interest for C-14 are the consumption of vegetation by humans and milk from which animals have ingested C-14 through the consumption of vegetation. Wth the requirement to begin Page 5 of 79

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 70 of 800 reporting C-14 dose in 201 1 and the addition of C-14 to plant effluents, human dose in this category is primarily driven by the release of C-14 from the plant.

The hypothetical dose to the maximum exposed individual living near the station via ingestion of milk and vegetation was calculated. The source of milk and vegetation was assumed to be at the nearest site boundary with the cows pastured and vegetation grown from May through October. The maximum organ dose from radioactive iodine and particulate (including C-14) to any organ was 7.22E-0J mrem (child/bone) based on measured effluents and average meteorological data, and 6.95E-01 mrem (child/bone) based on measured effluents and concurrent meteorological data. The maximum dose from radioactive iodine and particulate (including 0-14) to the whole body was I .49E-01 mrem (child) based on measured effluents and average meteorological data, and I .46E-01 mrem (child) based on measured effluents and concurrent meteorological data.

Gaseous Total Dose The maximum total dose from gaseous releases to any organ was 7.22E-0J mrem (child/bone) based on measured effluents and average meteorological data, and 6.95E-0J mrem (child/bone) based on measured effluents and concurrent meteorological data. The maximum total dose from gaseous releases to the whole body was I .49E-01 mrem (child) based on measured effluents and average meteorological data, and I .46E-01 mrem (child) based on measured effluents and concurrent meteorological data.

LIQUID EFFLUENT PATHWAYS The principal pathways through the aquatic environment for potential doses to man from liquid waste are ingestion of potable water and eating aquatic foods. Liquid dose was calculated based on the ingestion of potable water and sport fish. It should be noted, however, there are currently no communities within 10 km downstream ofthe plant using the Rock River for drinking water. NRC-developed equations are used to calculate the doses to the whole body, bone, liver, thyroid, kidney, lung, lower GI tract, and skin. Specific parameters for use in the equations are given in the Exelon Offsite Dose Calculation Manual (ODCM).

The maximum dose from liquid releases to any organ was I .58E-01 mrem (adult/gilli). The maximum dose from liquid releases to the whole body was I .40E-01 mrem (adult).

GASEOUS + LIQUID TOTAL DOSE The maximum total dose to any organ via both gaseous and liquid effluents is 7.22E-01 mrem (child/bone). The maximum dose to the whole body via both gaseous and liquid effluents is 2.66E-01 mrem (child).

Dose Limits to Members of the Public Byron Station did not exceed any of the dose limits as shown below based on concurrent or historical meteorological data.

The limits on dose or dose commitment to a member of the public due to radioactive materials in liquid effluents from each reactor is I .5 mrem to the whole body or 5 mrem to any organ during any calendar quarter and 3 mrem to the whole body or JO mrem to any organ during a calendar year.

The limits on air dose due to noble gases released in gaseous effluents to a member of the public from each reactor is 5 mrad for gamma radiation or JO mrad for beta radiation during any calendar quarter and 10 mrad for gamma radiation or 20 mrad for beta radiation during a calendar year.

. The limits on dose to a member of the public due to radioactive iodine & particulate with half-lives greater than eight days in gaseous effluents released from each reactor is 7.5 mrem to any organ during any calendar quarter and 15 mrem to any organ during a calendar year.

The annual I OCFR2O limit on Total Effective Dose Equivalent to individual members of the public is I 00 mrem.

The 4OCFRI9O limits on individual members ofthe public is 25 mrem to the whole body, 25 mrem to any organ (except thyroid), and 75 mrem to the thyroid.

SITE METEOROLOGY Detailed records of the site meteorological measurements taken during each calendar quarter of the year are maintained by the meteorological vendor, retained on site, and are available upon request.

The data are presented as cumulative joint frequency distributions of the wind direction for the 250 level and wind speed class by atmospheric stability class determined from the temperature difference between the 250 and 30 levels. Data recovery for all measurements on the meteorological tower was 99.7% during 2015.

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 140 of 800 Process Control Program (PCP) for Radioactive Wastes RW-AA- 1 00, Process Control Program (PCP) for Radioactive Waste, Revision 1 1 was implemented in June, 2015. The revision incorporated the following changes:

The terms and definitions were alphabetized and some had updated definitions as follows:

2. TERMS AND DEFINITIONS

2.1. Blending

The mixing of LLRWwith different concentrations of radionuclides, typically in an effort to create a relatively homogeneous mixture for disposal.

2.2. Classification Controlling Nuclides: One or more nuclides, listed in Table I or Table 2 of IOCFR61 .55, whose concentration is the specific basis for the classification of the waste container. This could be a single nuclide or multiple nuclides that make up >50% of the sum of the fractions.

2.3. Compaction

When dry wastes such as paper, wood, plastic, cardboard, incinerator ash, and etc. are volume reduced through the use of a compactor.

2.4. Concentration Averaging: The averaging of the radionuclide concentrations for specific wastes or mixture of waste over the volume or weight of the waste.

2.5. Dewatering

The process of removing fluids from liquid waste streams to produce a waste form that meets the requirements of I OCFR Part 61 and applicable burial site criteria, <0.5% by volume when the waste is packaged to an unstable state, or

<1 % by volume when the waste is packaged to a stable form.

2.6. Encapsulation

Encapsulation is the surrounding of a radioactive source or component with a nonradioactive material. Encapsulation involves a radioactive core surrounded by a non-radioactive matrix.

2.7. High Integrity Container (HIC): A disposable container that is approved to the Requirements of IOCFR6I. The use of HICs is an alternative to solidification or encapsulation in a steel container to meet burial stability. HICs are used to package dewatered liquid wastes, (e.g. filter cartridges, filter media, resin, sludges, etc), or dry active waste.

2.8. Homogeneous Waste: Waste in which concentrations of radionuclides of concern are likely to approach uniformity in the context of reasonable foreseeable intruder scenarios (This is because hot spots are a concern with respect to protection of an individual who may inadvertently intrude into the burial site).

2.9. Incineration, RVR, andlor Glass Vitrification of Liquid or Solid: Dry or wet waste processed via incineration and/or thermal processing where the volume is reduced by thermal means meets IOCFR6I requirements.

2.10. Liquid Waste Processing Systems: In-plant or vendor supplied processing systems consisting of equipment utilized for evaporation, filtration, demineralization, dewatering, compression dewatering, solidification, or reverse osmosis (RO) for the treatment of liquid wastes (such as Floor Drains, Chemical Drains and Equipment Drain inputs).

2. 1 1 Mixable Waste: Waste that is amenable to physical mixing to create relatively uniform radionuclide concentrations.

2. 1 2. Nuclides of Concern: A nuclide in the waste in concentrations greater than 1 % of Page 13 of 79

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 150 of 800 the concentration of that nuclide listed in Table I of IOCFR61 .55 or 1 % of the applicable class-dependent concentration of that nuclide in Table 2 of I OCFR61 .55, Column 2 or 3.

2.13. Process Control Program (PCP): The program which contains the current formulas, sampling, analysis, tests, and determinations to be made to ensure that processing and packaging of solid radioactive waste based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure the waste meets the stabilization criteria specified in I OCFR Parts 20, 61 and 71, state regulations, and burial site requirements.

2.14. Solidification: Liquid waste processed to either an unstable or stable form per I OCFR6I requirements. Waste solidified does not have to meet the 300-year free standing monolith criteria. Approved formulas, samples and tests do not have to meet NRC approval for wastes solidified in a container meeting stability criteria (e.g.

High Integrity Container).

2.15. Solidification Media: An approved media (e.g. Barnwell vinyl ester styrene, cement, bitumen) when waste containing nuclides with greater than 5-year half lives is solidified in a container with activity greater than I micro curie/cc. Waste solidified in a HIC is approved by the commission meeting the IOCFR6I stabilization criteria, including I % free standing liquids by volume when the waste is packaged to a stable form and < 0.5% when waste is packaged to an unstable form. The formulas, sampling, analysis, and test do not require NRC approval, because the HIC meets the stability criteria.

2.15.1. Solidification to an unstable or stable state is performed by vendors, when applicable. Liquid waste solidified to meet stabilization criteria (IOCFR6I and 01-91 Branch Technical Requirements) shall have documentation available that demonstrates that the process is approved by the NRC or disposal facility.

2.16. Stabilization: Liquid waste processed to a stable state per IOCFR61 Requirements. Established formulas, samples, and tests shall be approved by the NRC in order to meet solidification stabilization criteria. This processing method is currently not available, because the NRC recognizes that waste packed in a High Integrity Container meets the 300-year stabilization criteria. In the event that this processing method becomes an acceptable method, then the NRC shall approve the stabilization formulas, samples, tests, etc.

2. 1 7. Waste Streams: Consist of but are not limited to Filter media (powdered, bead resin and fiber),

Filter cartridges, Pre-coat body feed material, Contaminated charcoal, Fuel pool activated hardware, Oil Dry absorbent material added to a container to absorb liquids Fuel Pool Crud Sump and tank sludges, High activity filter cartridges, Concentrated liquids, Contaminated waste oil, Dried sewage or wastewater plant waste, Dry Active Waste (DAW): Waste such as filters, air filters, low activity cartridge filters, paper, wood, glass, plastic, cardboard, hoses, cloth, and metals, etc, which have become contaminated as a consequence of normal operating, housekeeping and maintenance activities.

Other radioactive waste generated from cleanup of inadvertent contamination.

Section 4.2. 13 was updated to include NRC-2001-0022 as follows:

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE 180 of 800 Miscellaneous Information A. As required by Technical Specification 5.6.2, meteorological and environmental impact information is reported in the 2015 Annual Radiological Environmental Operating Report (AREOR) or is retained on file to be provided upon request.

B. No limits were exceeded during the 2015 reporting period in liquid hold up tanks or waste gas decay tanks as stated in Technical Specification 5.5.12.

C. There were no irradiated fuel shipments during the 2015 reporting period. An Independent Spent Fuel Storage Installation (ISFSI) campaign began in 2010 when used fuel was removed from the Spent Fuel Pool (SFP), placed into six (6) casks, each containing 32 fuel bundles, and transferred to an outdoor storage pad. No additional casks were placed on the pad in 201 1 In 2012, eight (8) additional casks were placed on the pad for a total offourteen (14) casks. No additional casks were placed on the pad in 2013 or 2014. In 2015, six (6) additional casks were placed on the pad for a total oftwenty (20) casks. Prior to the ISFSI campaign, additional dosimeters were placed at the site boundary nearest to the storage pad (in between the pad and the nearest resident) for the purpose of measuring any potential offsite dose to the public from the storage pad. Since the dosimeters were placed, data from the dosimeters, when compared to the existing environmental dosimeters in the surrounding area, have shown no statistical difference. As a result, there is currently no offsite dose contribution from the ISFSI facility or any other on-site storage facility, including the Dry Active Waste (DAW) Building and the Old Steam Generator (OSG) Storage Building, as evidenced by dosimetry data that is indistinguishable from the existing environmental dosimeters.

D. There were no REMP sample results that exceeded any technical specification limits or analytical results investigation levels during the 2015 reporting period. REMP composite surface water samples from point BY-12, Rock River downstream of the plant liquid effluent discharge, detected tritium results of 490 pCi/L in the second quarter and 748 pCi/L in the third quarter, against a lower detection limit of 200 pCi/L. The positive sample results can be attributed to one or more weekly samples being obtained shortly after permitted liquid discharges, and are not unexpected. The results are well below the Technical Requirements Manual (TRM) reportable limit of 30,000 pCi/L. There are no communities using the Rock River for drinking water within I 0 km downstream of the station. No radionuclides that were a result of plant effluents were detected in any of the other REMP samples.

E. There were no elevated releases during the 2015 reporting period. All planned gaseous releases were discharged by way of the plant vent stacks and are considered to be mixed mode releases.

F. There was one liquid effluent flow loop that exceeded its inoperability time limit as stated in TRM TLCO 3.1 1 .b. On 4/3/15 01 :53, OW)(001 Liquid Radwaste Release High Flow Loop, entered OBOL I I .a due to calibration procedure OBISR 1 1 .a.3-005. The procedure requires a channel check for operability following completion of the calibration. The channel check requires process flow through the loop and could not be completed within the required 30-day time frame because there were no liquid releases performed during this time utilizing the high flow loop. The flow loop (high/low) to be utilized during liquid releases is contingent upon the radioactivity (i.e. tritium) concentration present in the release tank. The condition was exited on 5/8/15 13:21, when a liquid release was ableto be performed utilizing the high flow loop.

G. There were no unplanned gaseous or liquid releases to unrestricted areas during the 2015 reporting period.

H. All Rock River flow measurements during liquid effluent discharges were obtained from the U.S.

Geological Survey Byron Gauging Station for the Rock River with the following exceptions. Due to icing Page 17 of 79

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 190 of 800 conditions near the Byron gauging station, flows were obtained from the Rockton flow gauge, located on the Rock River approximately 30 miles upstream of the Byron flow gauge, during the liquid effluent releases on 1/21/15 and 1/30/15. Due to icing conditions near the Byron and Rockton gauging stations, the Rock River flow measurement during the liquid effluent release on 1/9/15 was obtained from the Dixon flow gauge, located approximately 32 miles downstream of the Byron flow gauge.

History: This message has been replied to and forwarded.

Barry, Yes, I would agree that is a reasonable approach. Rememberthat the 10CFR5O Appendix I dose is more restrictive than 4OCFRI9O doses, so compliance with 4OCFR19O is demonstrated by compliance with Appendix I.

The only thing 4OCFR19O adds is direct radiation dose from plant structures and on-site storage facilities. There is no additional dose from plant structures and on-site storage facilities as we state each year in the Miscellaneous Info section ofthe ARERR.

So Im thinking that the 4OCFR19O dose reports may not even be necessary if you would prefer to leave them out.

Fw: [EXTERNAL] BYR16-012-Comment Issue related to 4OCFR19O Compliance

Jeff, There appears to be confusion below on when and how a thyroid dose and an Other Organ!

Any Organ dose is used to determine 4OCFRI9O compliance.

The following text is extracted from the 2015 Byron ARERR:

file:///C:/Users/O59455/AppData/Local/Temp/notes5D3EFE/web 1 372.htm 11/12/2016

J_ c15/ h IL -r ANALYSIS NO. BYRI6-012 REVISION 0 PAGE 6R of 8R The 4OCFRI 90 limits on individual members of the public is 25 mrem to the whole body, 25 mrem to any organ (except thyroid), and 75 mrem to the thyroid.

From the 4OCFRI 90 RETDAS word file above, the logic of the program allows Any Organ to include a thyroid, in this case an Infant Thyroid. The program prints out the age group/organ dose (for all ages) for the liquid releases, but only prints the maximum dose limit age group/organ dose results for Iodine and Particulate gaseous releases (I & P, Non-noble gas). Thus the teen liver liquid doses cannot be used for Other/Any Organ comparison to 25 mrem, since I & P gaseous results for the various organ/age groups are not printed out and therefore cannot be added to the organ liquid doses to obtain the maximum organ dose.

In our particular scenario for Calculation BYRI6-012, the calculated result of 1.97E+O1 mrem meets both criteria of 25 mrem and 75 mrem. I propose eliminating the Other/Any Organ row from the table below and adding a footnote that states since the calculated value of I .97E+O1 for the infant thyroid is less than 25 mrem and since the thyroid dose is the limiting organ dose, then the Any Organ criteria is also met.

Do you agree that this is workable path froward?

Thank you for you support.

ANALYSIS NO. BYRI6-012 REVISION 0 PAGE ZR of 8R Extracted OAR Comment:

I do not see this tabulated in Attachments L or M. I see the values duplicate those for Infant thyroid. Is infant thyroid assumed to be the same dose as other organ? If that is the answer, can you add an explanation and basis?

See below Extracted table from OAR evolution of Calculation of BYRI6-012:

Table 2.13-1 4OCFRI9O UNFILTERED ANNUAL DOSE BY ORGAN AND AGE GROUP (mrem)

Gaseous Dose Liquid Dose Component Total Dose ODCM Regulatory Age Group Component (mremlyr) (mrem/yr) Dose Limit Matrix Organ (mrem/yr) (mrem/yr)

Child Total Body Z.21E-03 5.05E-O1 5.12E-O1 25 Infant Thyroid 5.16E-03 J.96E+OJ 1.97E+O1 75 Infant Other Organ 516E-03 1.96E+O1 1.97E+O1 25 The yellow4;igfflighted text is not quite correct. The thyroid dose is the highest organ dose. so meeting 25 nwem for the thyroid dose meets the 25 mrem limit for other organ.

The 4OCFRI9O refresher file contains the following as a last sentence: When calculating dose due to non-noble gases, the age group and organ with the highest dose from non-noble gases is used.

The word file is a RETDAS report UNFILTERED. 4OCFRI9O compliance is defined in Table 1-1 ofthe Byron ODCM on Page 33:

Total Body Dose -25 mrem/year Thyroid Dose - 75 mrem/year Other Organ Dose - 25 mrem/year Non-noble gas means iodines and particulates in the gaseous and liquid effluent. Correct? Non-noble gas means iodines, particulates, tritium, and carbon- 1 4 in gaseous effluents only. Noble gases are not taken into consideration in liquid releases under Appendix I but there is a total noble gas effluent concentration limit under I OCfR2O.

Age age group and organ with the highest dose from non-noble gases. RETDAS uses the term Any Organ. In the OAR evolution of this calculation, I placed Infant Thyroid dose results in both classifications, Thyroid Dose and Other Organ Dose. See above comment. The age group and organ with the highest dose is infant thyroid.

Combining the above thoughts, Other Organ/Any Organ means the age group and organ with the highest dose from non-noble gases, excluding the thyroid organ. Correct? Correct Thank you for your support, file:///C:/Users/O59455/AppDatafLocal/Temp/notes5D3EFE/web1 3 72.htm 1 1/12/20 16

Filtered Reports

Barry, Attached are copies ofthe filtered Unit 1 and Unit 2 Gaseous dose reports, along with the filtered 4OCFR19O dose report.

These reports would represent the off-site dose prior to the engineering change. The filtered dose reports assume 5.1E-02 Ci/yr of -131 and 7.OE-02 Ci/yr of -133. The liquid dose reports would, obviously, remain unchanged.

You will notice the organ dose rates on the Instantaneous Filtered report were unchanged. This is because the limiting receptor in calculating instantaneous dose rates to organs is due to inhalation of non-noble gas (i.e. iodine). Ingestion dose file:///C:Users/O59455/AppData/Local/Temp/notesFFF692/web4O87.htm 9/15/2016

-t - -

ANALYSIS NO. BYRJ6-012 REVISION 0 PAGE 5T of lOT factors are not used in the calculation of instantaneous organ dose rates. The inhalation dose factors for iodine are much lower than the ingestion dose factors.

As we discussed on the phone, I am currently looking into a potential issue with the instantaneous dose report. Before we use the results from that report, I need to better understand what that report is actually telling us. I am awaiting response from Canberra. The rep is out oftown this week.

Also, I will need an AT, due 4/15/17, cut from the EC to include a summary of the engineering change in the 2016 Annual Radiological Effluent Release Report (ARERR).

U2 Gaseous Annual.docx U2 Liquid Annual.docx Barry/John, The doubling ofthe liquid discharge flow rates did not change the liquid doses because the permits were based on average effluent concentrations, which did not change.

Attached are the dose reports that have been reviewed by my supervisor (Z. Cox). I only ran annual dose reports because the Appendix I annual dose limits are twice the quarterly limits. Since we are using average effluent concentrations, once we demonstrate compliance to annual limits we automatically demonstrate compliance to quarterly limits. RETDAS is very temperamental, so when you look at the reports, ignore the listed monthly and quarterly limits and focus only on the annual limits. The gaseous and liquid annual reports demonstrate 10CFR5O Appendix I (per unit) compliance, the 4OCFR19O report demonstrates 4OCFR19O (site) compliance, and the gaseous instantaneous report demonstrates 10CFR2O (site) compliance. Give me a call tomorrow and we can discuss them.

Aftertomorrow, I will be out ofthe office until Wednesday.

One a station basis, the gpm dilution flow in UFSARTabIe I I .2-2 would also double, thus maintaining the same liquid effluent concentration into the discharge canal.

LIQUID RELEASES The annual average radwaste dilution flow is 13000 gpm and is tabulated in UFSAR Table I 1.2-2 (6649). The annual liquid releases for the unit are presented in UFSAR Table I I .2-1.

RE: [EXTERNAL] Byron Liquid Releases and Airborne Releases- per Unit or per Station

Barry, I think there may have been a misunderstanding. I dont believe we concluded the liquid effluent concentrations listed in the UFSAR were on a station basis. But I believe that I stated the liquid effluent concentrations (uCi/mI) needed to be listed on a station basis because that is the way they are required to be input to RETDAS. When a liquid release permit is created, it is a single permit. RETDAS subsequently allocates the curies and dose evenly between units.

So it sounds like the values in Table 11.2-1 just need to be doubled.

[EXTERNALJ Byron Liquid Releases and Airborne Releases- per Unit or per Station Jeff In our conference call of 7/14/2016 we discussed UFSAR Table 11.2-1 for expected annual liquid releases into the discharge canal. UFSAR Table I I .3-6 is the expected annual airborne release per unit as indicated by the double asterisk in the table title. The point of this discussion was UFSAR Table I I .2-1 an expected annual release to discharge canal per unit or per station. Since UFSAR Table 1 1 .3-6 is explicitly annual release per unit, we concluded that UFSAR Table I 1 .2-1 is per station due to the absence of the per unit designation.

However, during the preparation of the draft calculation I was preparing a section of the calculation on the power uprate impact on normal operation source terms, airborne and liquid, UFSAR Section 1 1 .3.3.4 and UFSAR Table I I .3-7 and UFSAR Section 1 1 .2. 1 .3 and UFSAR Table I I .2-4, respectively.

The following tables are extracted directly from the UFSAR for comparison purposes:

LIQUID RELEASES Comparing the Total column of Table 1 1 .2-1 with the Expected Release column of Table I 1 .2-4 shows that they tabulate the same annual releases, accounting for rounding. Note the units of release in the two tables, Ci/yr in Table I I .2-1 and Ci/yr/unit in Table I I .2-4. The conclusion previously drawn on liquid releases being on a station basis was not correct. Based on Table I I .2-4, the units of release are Cl/yr/unit not Cl/yr/station.

AIRBORNE RELEASES Note the double asterisk in the title of Table 1 1 .3-6 indicating that the table is on a per unit basis. In Table 11.3-7, the 2nd column is entitled Annual Release From One Unitt. Therefore, these two tables explicitly indicate the annual releases are on a per unit basis.

In summary, liquid releases and airborne releases are in terms of Ci.yr/unit in Chapter 1 1 of the UFSAR.

New PDFs for liquid releases are in preparation and are being reviewed..

REIDAS was updated from v3.6.4.8 to v3.6.4.9. The update was to correct the error in the instantaneous Site Period Dose Rate report module only and did not involve a change in the source code. Therefore the V&V testing, which was performed on Version 3, still remains valid. The RETDAS reports only display v3.6.4 so there is no need to run another instantaneous Site Period Dose Rate Report.

9, 2015 Radiological Groundwater Protection Program (RGPP) Results Summary:

In 2015, fifteen (15) Radiological Groundwater Protection Program (RGPP) monitoring wells were sampled in total. Groundwater samples were obtained in March, May, August, and November and analyzed for tritium. In addition, a study of gamma, gross beta, and gross alpha radioisotopes was performed in accordance with Nuclear Energy Institute (NEI) 07-07, Groundwater Protection Initiative, for the samples obtained in May. None of the May samples showed concentrations of radionuclides above what is considered background levels. Three wells contained levels of tritium above the lower limit ofdetection (LLD) of200 pCi/L. They were: AR-A (493 pCi/L in March, 723 pCi/L in May, 417 Page 3 of 79

ANAlYSIS NO BYRIS-012 REVISION 0 PAGE 67U of 158U ANAlYSIS NO. BYR16O12 REVISION 0 PAGE 50 of 800 pCIIL in August, 450 pCi/L in November) and AR-I I (945 pCi/L in March, 839 pCi/L in May, 422 pCi/L in August, 1040 pCi/L in November). Wells AR4 and AR-I I are near the Circulating Water Bfowdown piping, where historical leakage through vacuum breakers was known to have occurred. Tritium concentrations in these wells have gradually decreased since being first sampled in 2006. In 2015, tritium was measured in Well AR-f, located on-site, just west plant structures, at concentrations ranging between the lower limit of detection (200 pCi/L) and 508 pCi/L. Tritium has been measured in this welt just above detectable limits on an intermittent basis since the well was first drilled in 2006. The tritium present in this well is at or below tritium levels that have been measured in rainwater as a result of precipitation recapture from permitted gaseous releases and it is not believed to be the result of new leak(s). In August 2014, a break in the well piping was discovered about six feet below the surface that could have served as the entry point for tritium in the recapture water. Should the water in these aquifers migrate to off-site wells used for drinking, the off-site dose consequence from tritium present in any of these three wells would be negligible. There are no existing or new teaks evident at the site and all groundwater well sample results are well below the drinking water standard of 20,000 pCiIL tritium.

SUMMARY

Calculations based on gaseous and liquid effluents and meteorological data indicate that public dose due to radioactive material attributable to Byron Station during the period did not exceed any regulatory or Offsite Dose Calculation Manual (ODCM) limits.

The Total Effective Dose Equivalent (TEDE) due to licensed activities at Byron Station calculated for the maximum exposed individual for the period is 2.66E-01 mrem. The annual limit on TEDE is 100 mrem.

The assessment of radiation doses to the public is performed in accordance with the ODCM. The results of these analyses confirm that the station is operating in compliance with I OCFR5O Appendix I, IDCFR2O and 4OCFRI9O.

There were no additional operational controls implemented in 201 5 that affected radiological effluents.

There were no measurements which exceeded the reporting levels, including any that would not have been attributable to station effluents.

The results of the current radiological environmental monitoring program are approximately the same as those found during the pre-operational studies conducted at Byron Station.

A total of 3,32E+03 curies of tritium were discharged with a maximum quarterly average concentration of 1.56E-04 uCi/mI.

A total of 5.08E-04 curies of dissolved and entrained gases were discharged with a maximum quarterly average concentration of 5.56E-1 I uCi/mI.

Gross alpha-emitting radionuclides were below detectable limits.

DOSE TO MAN GASEOUS EFFLUENT PATHWAYS Noble Gas Dose Rates Offsite Gamma air and whole body dose rates for the period were calculated based on measured release rates, isotopic composition of the noble gases, and average meteorological data. The maximum gamma air dose was 1.76E-02 mrad based on measured effluents and average meteorological data, and 3.19E-03 mrad based on measured effluents and concurrent meteorological data.

Noble Gas Beta Air and Skin Dose Rates The range of beta particles in air is relatively small (on the order of a few meters or less).

Consequently, plumes of gaseous effluents may be considered semi-infinite for the purpose of calculating the dose from beta radiation incident on the skin. However, the actual dose to sensitive skin tissues is difficult to calculate due to the effect of the beta particle energies, thickness of inert skin, and clothing covering sensitive tissues. For purposes of this report the skin is taken to have a thickness of 7.0 mg/cm2 and an occupancy factor of I .0 is used. The maximum skin dose was 2.84E-04 mrem based on measured effluents and average meteorological data, and 2.97E-03 mrem based on measured effluents and concurrent meteorological data.

The maximum offsite beta air dose for the year based on measured effluents and average meteorological data was 8.55E-04 mrad, and 6.29E-04 mrad based on measured effluents and concurrent meteorological data.

Radioactive Iodine & Particulate The human thyroid exhibits a significant capacity to concentrate ingested or inhaled iodine. 1-131 released during routine operation of the station may be made available to man resulting in dose to the thyroid. C-14 is also included in this category. C-14 exhibits a capacity to concentrate in bone. C-14 is released in gaseous form and is absorbed into vegetation through photosynthesis. The principal pathways of interest for C-14 are the consumption ofvegetation by humans and milk from which animals have ingested C-14 through the consumption of vegetation.

The hypothetical dose to the maximum exposed individual living near the station via ingestion of milk and vegetation was calculated. The source of milk and vegetation was assumed to be at the nearest site boundary with the cows pastured and vegetation grown from May through October. The maximum organ dose from radioactive iodine and particulate (including C-14) to any organ was 7.22E-01 mrem (child/bone) based on measured effluents and average meteorological data, and 6.95E01 mrem (child/bone) based on measured effluents and concurrent meteorological data. The maximum dose from radioactive iodine and particulate (including C-f4) to the whole body was I .49E-01 mrem (child) based on measured effluents and average meteorological data, and I 46E01 mrem (child) based on measured effluents and concurrent meteorological data.

Gaseous Total Dgj The maximum total dose from gaseous releases to any organ was f.22E-01 mrem (child/bone) based on measured effluents and average meteorological data, and 6.95E-01 mrem (child/bone) based on measured effluents and concurrent meteorological data. The maximum total dose from gaseous releases to the whole body was I .49E-01 mrem (child) based on measured effluents and average meteorological data, and I .46E-01 mrem (child) based on measured effluents and concurrent meteorological data.

LIQUID EFFLUENT PATHWAYS The principal pathways through the aquatic environment for potential doses to man from liquid waste are ingestion of potable water and eating aquatic foods. Liquid dose was calculated based on the ingestion of potable water and sport fish. It should be noted, however, there are currently no communities within I 0 km downstream of the plant using the Rock River for drinking water. NRC-developed equations are used to calculate the doses to the whole body, bone, liver, thyroid, kidney, lung, lower GI tract, and skin. Specific parameters for use in the equations are given in the Exelon Offsite Dose Calculation Manual (ODCM).

The maximum dose from liquid releases to any organ was I .58E-01 mrem (adulUgilli). The maximum dose from liquid releases to the whole body was I .40E-01 mrem (adult).

GASEOUS + LIQUID TOTAL DOSE The maximum total dose to any organ via both gaseous and liquid effluents is 7.22E-01 mrem (child/bone) The maximum dose to the whole body via both gaseous and liquid effluents is 2.66E-01 mrem (child).

Dose Limits to Members of the Public Byron Station did not exceed any of the dose limits as shown below based on concurrent or historical meteorological data.

The limits on dose or dose commitment to a member of the public due to radioactive materials in liquid effluents from each reactor is I .5 mrem to the whole body or 5 mrem to any organ during any calendar quarter and 3 mrem to the whole body or I 0 mrem to any organ during a calendar year.

. The limits on air dose due to noble gases released in gaseous effluents to a member of the public from each reactor is 5 mrad for gamma radiation or I 0 mrad for beta radiation during any calendar quarter and I 0 mrad for gamma radiation or 20 mrad for beta radiation during a calendar year.

The 4OCFRI 90 limits on individual members of the public is 25 mrem to the whole body, 25 mrem to any organ (except thyroid), and 75 mrem to the thyroid.

SITE METEOROLOGY Detailed records of the site meteorological measurements taken during each calendar quarter of the year are maintained by the meteorological vendor, retained on site, and are available upon request.

The data are presented as cumulative joint frequency distributions of the wind direction for the 250 level and wind speed class by atmospheric stability class determined from the temperature difference between the 250 and 30 fevels. Data recovery for all measurements on the meteorological tower was 99.7% during 2015.

BYRI6-012 REVISION 0 PAGE 140 of 800 Process Control Program (PCP) for Radjpjctive Wastes RW-AA-1 00, Process Control Program (PCP) for Radioactive Waste, Revision I 1, was implemented in June, 201 5. The revision incorporated the following changes:

The terms and definitions were alphabetized and some had updated definitions as follows:

2. TERMS AND DEFINITIONS

2.1 Blending

The mixing of LLRW with different concentrations of radionuclides, typically in an effort to create a relatively homogeneous mixture for disposal.

2.2. Classification Controlling Nuclides: One or more nuclides, listed in Table I or Table 2 of I OCFR6I 55, whose concentration is the specific basis for the classification of the waste container. This could be a single nuclide or multiple nuelides that make up >50% of the sum of the fractions.

23. Compaction: When dry wastes such as paper, wood, plastic, cardboard, incinerator ash, and etc. are volume reduced through the use of a compactor.

2.4. Concentration Averaging: The averaging of the radionudide concentrations for specific wastes or mixture of waste over the volume or weight of the waste.

2.5. Dewatering

The process of removing fluids from liquid waste streams to produce a waste form that meets the requirements of IOCFR Part 61 and applicable burial site criteria, <0.5% by volume when the waste is packaged to an unstable state, or

<1% by volume when the waste is packaged to a stable form.

2.6. Encapsulation

Encapsulation is the surrounding of a radioactive source or component with a nonradioactive material. Encapsulation involves a radioactive core surrounded by a non-radioactive matrix.

2.7. High Integrity Container (HIC): A disposable container that is approved to the Requirements of IOCFR6I The use of HICs is an alternative to solidification or encapsulation in a steel container to meet burial stability. HICs are used to package dewatered liquid wastes, (e.g. filter cartridges, filter media, resin, sludges, etc), or dry active waste.

2.8. Homogeneous Waste: Waste in which concentrations of radionuclides of concern are likely to approach uniformity in the context of reasonable foreseeable intruder scenarios (This is because hot spots are a concern with respect to protection of an individual who may inadvertently intrude into the burial site).

2.9. Incineration, RVR, and!or Glass Vitrification of Liquid or Solid: Dry or wet waste processed via incineration and/or thermal processing where the volume is reduced by thermal means meets IOCFR61 requirements.

2.10, Liquid Waste Processing Systems: In-plant or vendor supplied processing systems consisting of equipment utilized for evaporation, filtration, demineralization, dewatering, compression dewatering, solidification, or reverse osmosis (RO) for the treatment of liquid wastes (such as Floor Drains, Chemical Drains and Equipment Drain inputs).

2.1 1 Mixable Waste: Waste that is amenable to physical mixing to create relatively uniform radionuclide concentrations.

2.12. Nuclides of Concern: A nuclide in the waste in concentrations greater than 1% of Page 13 of 79

601 2 RflWO PAGE4V5 7Jfr%&8U the concentration of that nuclide listed in Table I of I OCFR6I .55 or I % of the applicable class-dependent concentration ofthat nuclide in Table 2 of IOCFR6I 55, Column 2 or 3.

2.13. Process Control Program (PCP): The program which contains the current formulas, sampling, analysis, tests, and determinations to be made to ensure that processing and packaging of solid radioactive waste based on demonstrated processing of actual or simulated wet solid wastes will be accomplished in such a way as to assure the waste meets the stabilization criteria specified in IOCFR Parts 20, 61 and 71 state regulations, and burial site requirements.

2.14. Solidification: Liquid waste processed to either an unstable or stable form per I OCFR6I requirements. Waste solidified does not have to meet the 300-year free standing monolith criteria. Approved formulas, samples and tests do not have to meet NRC approval for wastes solidified in a container meeting stability criteria (e.g.

High Integrity Container).

2.1 5. Solidification Media: An approved media (e.g. Barnwell vinyl ester styrene, cement, bitumen) when waste containing nuclides with greater than 5-year half lives is solidified in a container with activity greater than I micro curie/cc. Waste solidified in a HIC is approved by the commission meeting the IOCFR6I stabilization criteria, including I % free standing liquids by volume when the waste is packaged to a stable form and < 0.5% when waste is packaged to an unstable form. The formulas, sampling, analysis, and test do not require NRC approval, because the HIC meets the stability criteria.

2.1 5.1 Solidification to an unstable or stable state is performed by vendors, when applicable. Liquid waste solidified to meet stabilization criteria (IOCFR6I and 01-91 Branch Technical Requirements) shall have documentation available that demonstrates that the process is approved by the NRC or disposal facility.

2.16. Stabilization: Liquid waste processed to a stable state per 10CFR6I Requirements. Established formulas, samples, and tests shall be approved by the NRC in order to meet solidification stabilization criteria. This processing method is currently not available, because the NRC recognizes that waste packed in a High Integrity Container meets the 300-year stabilization criteria. In the event that this processing method becomes an acceptable method, then the NRC shall approve the stabilization formulas, samples, tests, etc.

2.17. Waste Streams: Consist of but are not limited to Filter media (powdered, bead resin and fiber),

Filter cartridges, Pre-coat body feed material, Contaminated charcoal, Fuel pool activated hardware, Oil Dry absorbent material added to a container to absorb liquids Fuel Pool Crud Sump and tank sludges, High activity filter cartridges, Concentrated liquids, Contaminated waste oil, Dried sewage or wastewater plant waste, Dry Active Waste (DAW): Waste such as filters, air filters, low activity cartridge filters, paper, wood, glass, plastic, cardboard, hoses, cloth, and metals, etc, which have become contaminated as a consequence of normal operating, housekeeping and maintenance activities.

Other radioactive waste generated from cleanup of inadvertent contamination.

Section 4.2.13 was updated to include NRC-2001-0022 as follows:

As required by Technical Specification 562, meteorological and environmental impact information is reported in the 2015 Annual Radiological Environmental Operating Report (AREOR) or is retained on file to be provided upon request.

B No limits were exceeded during the 201 5 reporting period in liquid hold up tanks or waste gas decay tanks as stated in Technical Specification 55i2.

C. There were no irradiated fuel shipments during the 2015 reporting period. An Independent Spent Fuel Storage Installation (ISFSI) campaign began in 2010 when used fuel was removed from the Spent Fuel Pool (SFP), placed into six (6) casks, each containing 32 fuel bundles, and transferred to an outdoor storage pad. No additional casks were placed on the pad in 2011 in 2012, eight (8) additional casks were placed on the pad for a total of fourteen (14) casks. No additional casks were placed on the pad in 2013 or 2014. In 2015, six (6) additional casks were placed on the pad for a total of twenty (20) casks. Prior to the I$FSI campaign, additional dosimeters were placed at the site boundary nearest to the storage pad (in between the pad and the nearest resident) for the purpose of measuring any potential offsite dose to the public from the storage pad. Since the dosimeters were placed, data from the dosimeters, when compared to the existing environmental dosimeters in the surrounding area, have shown no statistical difference. As a result, there is currently no offsite dose contribution from the ISFSI facility or any other onsite storage facility, including the Dry Active Waste (DAW) Building and the Old Steam Generator (OSG) Storage Building, as evidenced by dosimetry data that is indistinguishable from the existing environmental dosimeters.

D. There were no REMP sample results that exceeded any technical specification limits or analytical results investigation levels during the 2015 reporting period. REMP composite surface water samples from point BY-12, Rock River downstream of the plant liquid effluent discharge, detected tritium results of 490 pCi/L in the second quarter and 748 pCitL in the third quarter, against a lower detection limit of 200 pCilL. The positive sample results can be attributed to one or more weekly samples being obtained shortly after permitted liquid discharges, and are not unexpected. The results are well below the Technical Requirements Manual (TRM) reportable limit of 30,000 pCi/L. There are no communities using the Rock River for drinking water within I 0 km downstream of the station. No radionuclides that were a result of plant effluents were detected in any of the other REMP samples.

E. There were no elevated releases during the 201 5 reporting period. All planned gaseous releases were discharged by way of the plant vent stacks and are considered to be mixed mode releases.

F. There was one liquid effluent flow loop that exceeded its inoperability time limit as stated in TRM TLCO

3. 1 1 .b. On 4/3/1 5 01 :53, OWXOOI Liquid Radwaste Release High Flow Loop, entered OBOL I I .a due to calibration procedure O8ISR I I .a.3-005. The procedure requires a channel check for operability following completion of the calibration. The channel check requires process flow through the loop and could not be completed within the required 30day time frame because there were no liquid releases performed during this time utilizing the high flow loop. The flow loop (high/low) to be utilized during liquid releases is contingent upon the radioactivity (i.e. tritium) concentration present in the release tank. The condition was exited on 5/8/15 13:21, when a liquid release was able to be performed utilizing the high flow loop.

G. There were no unplanned gaseous or liquid releases to unrestricted areas during the 201 5 reporting period.

H. All Rock River flow measurements during liquid effluent discharges were obtained from the U.S.

Geological Survey Byron Gauging Station for the Rock River with the following exceptions. Due to icing Page 17 of 79
