The proposed amendment is required to support fuel loading during the Unit 2 refueling outage scheduled for Spring 2021. Thus, Susquehanna requests NRC approval of the proposed changes and issuance of the requested license amendment by January 31,2021. Once approved the amendment shall be implemented within 90 days.

By letter dated July 15, 2019 (ADAMS Accession No. ML19196A270), Susquehanna submitted a request for an amendment to the TS to adopt Advanced Framatome Methodologies. The July 15 submittal was also requested to be approved by January 31, 2021, in order to support fuel loading during the Unit 2 refueling outage scheduled for Spring 2021. While both amendments are required to be approved in order to operate the SSES units with ATRIUM 11 fuel, neither amendment relies upon the other for approval. All infonnation necessary for the NRC to complete its review is present in each application and the NRC could issue the amendments in any order without regards to the results of the other review. Therefore, the two submittals are not "linked" as defined in NRC Office Instruction LIC-1 09, "Acceptance Review Procedures."

In accordance with 10 CFR 50.91, Susquehanna is providing a copy of this application, with enclosures, to the designated Commonwealth of Pennsylvania state official.

Both the Plant Operations Review Committee and the Nuclear Safety Review Board have reviewed the proposed changes.

Should you have any questions regarding this submittal, please contact Ms. Melisa Krick, Manager- Nuclear Regulatory Affairs, at (570) 542-1818.

This letter contains no new or revised regulatory commitments.

1. Summary Description Pursuant to 10 CFR 50.90, Susquehanna Nuclear, LLC (Susquehanna), is submitting a request for an amendment to the Updated Final Safety Analysis Report (FSAR) and Technical Specifications (TS) for the Susquehanna Steam Electric Station (SSES), Units 1 and 2, Facility Operating License numbers NPF-14 and NPF-22. The proposed amendment would modify the Current Licensing Basis (CLB) for the Design Basis Accident (DBA) Loss of Coolant Accident (LOCA) analysis described in the SSES FSAR, as previously reviewed by the NRC. The proposed changes would utilize an updated version of the ORIGEN code, introduce a new source term to account for the introduction of ATRIUM 11 fuel, use new inputs/assumptions that decrease the assumed Emergency Safety Feature (ESF) leakage into secondary containment, increase the assumed maximum allowable Standby Gas Treatment (SGT) System exhaust flow rate from secondary containment, and increase the allowed control structure unfiltered inleakage that is assumed in the DBA LOCA dose analysis. As a result, the proposed amendment would modify TS 5.5.2, Primary Coolant Sources Outside Containment, and the TS Bases for TS 3.6.4.1, Secondary Containment.

2. Detailed Description NRC review and approval is requested for the following changes associated with accident source term calculation methodology and with the LOCA parameters for postulated accident analysis. Enclosure 2 provides a summary table of the inputs and assumptions used in the Susquehanna LOCA analysis. These changes will support loading ATRIUM 11 fuel and will increase margin for surveillance testing.

2.1 Accident Source Term The current approved (Reference 1) accident radionuclide activity source term for the SSES core containing ATRIUM 10 fuel was generated using the SAS2H/ORIGEN-S version of the ORIGEN code from SCALE 4.4a. The core radionuclide activity inventory for the new ATRIUM 11 fuel was generated using a revised version of the ORIGEN code, TRITON/ORIGEN-ARP from SCALE 6.2.3 (Reference 2). The proposed change is required to support loading ATRIUM 11 fuel in Spring 2021.

2.2 Emergency Safety Feature System Leakage The current approved LOCA analysis utilizes a total of 20 gpm of flow through the ESF leakage pathway. This includes 5 gpm to account for ESF leakage and an additional (non-ESF) potential leakage of 15 gpm. The proposed change removes the additional (non-ESF) leakage from the

Enclosure 1 to PLA-7823 Page 2 of 19 flowpath so that the LOCA analysis will utilize a total of 5 gpm of flow through the ESF leakage pathway.

The revision to ESF leakage pathways results in changes to FSAR Sections 6.2.4.3.2.3, 15.6.5.5.1.2, and 18.1.69.3 as well as Tables 6.2-22 and 15.6-22. Additionally, the revision to ESF leakage pathways results in eliminating Scram Discharge from the list of systems within the scope of the Primary Coolant Sources Outside Containment Program in TS 5.5.2. provides marked-up TS pages for the proposed change; Enclosure 4 provides a clean version of the revised TS pages.

2.3 Secondary Containment Inleakage The FSAR describes the reactor building as designed to limit the inleakage to 140 percent of the secondary containment free volume per day at a vacuum of 0.25 inches water gauge (in. wg) while operating the SGT System. The proposed change would increase the inleakage limit to 225 percent per day, which requires increased SGT System flow following drawdown. As a result, the acceptance criteria for SGT System flow rate would increase; this change is reflected in the TS Bases for Surveillance Requirement (SR) 3.6.4.1.5. Enclosure 5 provides the marked-up TS Bases pages depicting the increased flow rate.

The increased secondary containment inleakage limit results in changes to FSAR Sections 6.2.3.2.1, 15.6.5.5.1.2, and 18.1.20.3.2.1.10 and Tables 6.2-17, 6.5-7, and 15.6-22.

2.4 Control Room Habitability Envelope Unfiltered Inleakage Control structure unfiltered inleakage of 500 cubic feet per minute (cfm) is a LOCA parameter for postulated accident analysis which has been used to evaluate control room dose consequence. The proposed change increases that assumed inleakage flow to 600 cfm. The unfiltered control structure inleakage testing acceptance criterion with Control Room Emergency Outside Air Supply (CREOAS) System in operation (emergency mode) will be increased to 600 cfm for this change. The accident dose model descriptions in FSAR Appendix 15B describe the Control Room Habitability Envelope (CRHE) dose model.

The increased CRHE unfiltered inleakage assumption results in changes to FSAR Sections 6.4.2.1 and 15B.2, and Table 15.6-22.

2.5 Control Room Habitability Envelope Continuous Occupancy Locations The CRHE for SSES Units 1 and 2 is defined in FSAR Figure 6.4-1A and includes the following rooms: Control Room, Technical Support Center (TSC), Backup Operational Support Center (OSC), computer, relay, cable spreading, HVAC and battery rooms for both Units 1

Enclosure 1 to PLA-7823 Page 3 of 19 and 2 (refer to Enclosure 7). Of these areas within the CRHE, the following are currently assumed to be continuously occupied following a DBA LOCA:

Control Structure Elevation 729-1 (All areas)

Control Structure Elevation 741'-1" (All areas)

Computer Room (Room C-202) at Elevation 698'-0" The proposed change reduces the continuous occupancy assumption to the following rooms following a DBA LOCA:

Main Control Room (Room C-409), Elevation 729-1

Technical Support Center (Room C-410), Elevation 741-1

Computer Room (Room C-202), Elevation 698-0 The proposed change to the continuous occupancy assumption results in changes to FSAR Sections 6.4.2.5 and 15B.2. This change has been determined to require NRC review and approval because the continuous occupancy assumptions were specifically repeated by the NRC in Reference 1.

2.6 Analysis Code (RADTRAD) Version The current approved dose analysis code per Reference 1 is RADTRAD Version 3.03. The DBA LOCA analysis will be performed with the updated RADTRAD Version 3.10.

2.7 Resultant Dose Consequences The aggregate dose effects to the analysis of record from the changes that are described above are shown in Table 4. The proposed changes result in dose consequences that remain within the regulatory limits of 10 CFR 50.67.

The aggregate impacts of the revised DBA LOCA dose analysis of record results in changes to FSAR Tables 15.6-11, 15.6-13, 15.6-14, 15.6-18, and 15.6-21.

3. Technical Evaluation The implementation of alternative radiological source term (AST) for SSES Units 1 and 2 was approved by the NRC in Amendment 239/216 (Reference 1). More recent revisions of calculations of the CRHE and offsite post-LOCA doses were approved by the NRC in

Enclosure 1 to PLA-7823 Page 4 of 19 Amendment 251/231 (Reference 3). Figure 1 provides a graphical representation of the release paths for the DBA LOCA and shows the relevant proposed changes; the changes are shown in bold and underlined. Enclosure 2 provides a summary table of the inputs and assumptions used in the Susquehanna DBA LOCA analysis.

ESF Leakage 5 gpm (0.668 cfm) 30day 3.1 Accident Source Term The current source term was developed for cores with ATRIUM 10 fuel using SAS2H/ORIGEN-S from SCALE 4.4.a (Reference 1). The SAS2H/ORIGEN-S code comprises

Enclosure 1 to PLA-7823 Page 5 of 19 an advanced version of ORIGEN, and is consistent with the source term code recommendations given by Regulatory Guide (RG) 1.183 (Reference 4), for generation of alternate source terms.

Susquehanna plans to load Framatome ATRIUM 11 fuel in spring 2021. The ATRIUM 11 core source term was developed using TRITON/ORIGEN-ARP from SCALE 6.2.3 (Reference 2).

The ATRIUM 11 assemblies are modeled in three axial segments based on part length fuel rod length. Each of the three axial segments use a region averaged power and moderator density.

Each region also uses a lattice library determined to be representative for the region. The libraries account for fuel lattice geometry at the selected axial elevation.

The current ORIGEN-S based core inventory uses an ATRIUM 10 fuel cycle with core thermal power of 4032 megawatt thermal (MWt) (102 percent of the SSES rated thermal power of 3952 MWt) and core average burnup of 39 gigawatt-days per metric ton of uranium (GWd/MTU). The proposed ORIGEN-ARP based core inventory uses an ATRIUM 11 fuel cycle with core thermal power of 4032 MWt and core average burnup of 41 GWd/MTU. The source term assumes a conservative fuel uranium mass and enrichment sensitivities were performed to bound the range of expected U-235 enrichments in ATRIUM 11 reload fuel.

ATRIUM 11 has a higher assembly uranium mass and higher core average burnup than ATRIUM 10, resulting in a conservative core source term for Susquehanna core designs.

The ATRIUM 11 reactor core radionuclide activity inventory will be used to calculate the radiological consequences of all DBAs that assume the release of reactor core activity. For the DBA LOCA, all fuel assemblies in the core are assumed to be affected and the core average inventory was used. The DBA Fuel Handling and Equipment Handling accident, and the DBA Control Rod Drop Accident are also impacted by the source term change; these analyses have been performed and the results will be implemented pursuant to 10 CFR 50.59 following the approval of this submittal.

3.2 Emergency Safety Feature System Leakage RG 1.183, Appendix A, identifies ESF System Leakage as a source of activity release for evaluating the radiological consequences of a DBA LOCA (compliance with RG 1.183 is discussed in SSES FSAR Section 3.13.1). RG 1.183 defines ESF systems as those systems that recirculate sump water outside of primary containment and these systems are assumed to leak during their intended operation. Two sources of potential suppression pool water leakage directly into secondary containment were conservatively included in the DBA LOCA release model for Susquehannas RG 1.183 AST submittal (approved in Reference 1). The first was ESF system leakage directly into secondary containment, consistent with RG 1.183, Appendix A. The leakage contribution from this source is 5 gpm. The total leakage from these systems is maintained less than 2.5 gpm in accordance with TS 5.5.2. This leakage was increased for the DBA LOCA dose analysis by a factor of two in accordance with RG 1.183, Appendix A.

Enclosure 1 to PLA-7823 Page 6 of 19 In addition to the 5 gpm ESF System leakage, a leakage of 15 gpm was assumed for suppression pool water leakage into secondary containment. This leakage was conservatively assumed to bound any leakage which could occur from other sources inside secondary containment including the Control Rod Drive (CRD) insert/withdrawal lines and the Scram Discharge Volume (SDV). This additional leakage is not ESF System leakage, is not required by RG 1.183, Appendix A, and was strictly included as a conservative assumption. Therefore, a total water leakage of 20 gpm was conservatively assumed for the DBA LOCA dose analysis for the initial AST submittal (refer to Section 3.1.1.3 of Reference 1).

This additional, conservative, non-ESF leakage of 15 gpm is not consistent with current modeling practices employed by the industry and is not consistent with the requirements of RG 1.183, Appendix A, for evaluating the radiological consequences of the DBA LOCA (i.e., it is not recirculated sump leakage). As such, it is being removed as an assumption in the DBA LOCA. Including the SDV in TS 5.5.2 is inconsistent with the standard TS contained in NUREG-1433 (Reference 5). Therefore, it is also being removed from TS 5.5.2 as shown in .

The Realistic LOCA analysis, which is bounded by the DBA LOCA analysis, also utilizes the current 20 gpm total ESF leakage value. The Realistic LOCA analysis has been re-performed utilizing the 5 gpm total ESF leakage value and the results will be implemented pursuant to 10 CFR 50.59 following the approval of this submittal.

3.3 Secondary Containment Inleakage The secondary containment structure completely encloses the primary containment structure such that a dual-containment design is utilized to limit the spread of radioactivity to the environment to within limits. The function of the secondary containment is to contain, dilute, and hold up fission products that may leak from primary containment into secondary containment following a DBA. The secondary containment boundary consists of the reactor building structure and associated removable walls and panels, hatches, doors, dampers, sealed penetrations and valves. The secondary containment is divided into Zone I, Zone II and Zone III, each of which must be OPERABLE depending on plant status and the alignment of the secondary containment boundary. Zones I and II are the portions of the reactor building below Elevation 779-1 surrounding the Unit 1 and Unit 2 primary containments, respectively.

Zone III consists of the portion of the reactor buildings above Elevation 779-1 with the exception of the HVAC equipment rooms which are not part of the secondary containment. The Unit 1 secondary containment boundary can be modified to exclude Zone II. Similarly, the Unit 2 secondary containment boundary can be modified to exclude Zone I.

The SSES TS Bases for SR 3.6.4.1.5 specifies the SGT System exhaust flow rate for various configurations. The proposed change would modify SGT System flow rates specified in Tables 1 and 2.

Enclosure 1 to PLA-7823 Page 7 of 19 Table 1: Flow Rates- Railroad Bay Aligned to Secondary Containment Secondary Containment Existing Flow Rates New Flow Rates Configuration (cfm) (cfm)

Zones I, II and III 5400 6400 Zones I and III 3900 6200 Zones II and III 4000 6300 Table 2: Flow Rates- Railroad Bay Aligned as No Zone Secondary Containment Existing Flow Rates New Flow Rates Configuration (cfm) (cfm)

Zones I, II and III 5300 6400 Zones I and III 3800 6000 Zones II and III 3900 6100 The proposed change will increase the allowable inleakage from 140 percent per day to 225 percent per day. This change is proposed in order to provide additional margin for secondary containment drawdown testing performed at SSES per SR 3.6.4.1.5. This change is necessary due to the unique nature of the SSES secondary containment configuration. The Unit 1 and 2 secondary containment at Susquehanna spans all eight elevations of the SSES reactor buildings and is divided into three zones with multiple isolation configurations. The secondary containment zones can be interconnected or remain independent based on unit operations. Additionally, the Unit 1 railroad bay can be excluded from secondary containment to support various maintenance activities (e.g., fuel deliveries). As a result of this flexibility, the SSES secondary containment boundary contains more penetrations than other similar sites, resulting in greater inleakage values. Additionally, the assumed SGT System flow rates must be greater to account for this greater inleakage and still be able to draw down the reactor building in the time assumed in the accident analyses. Based on the most recent testing, the inleakage value for the most limiting configuration (Zones II and III with the railroad bay aligned to secondary containment) was 3630 cfm compared to a limit of 4000 cfm. To provide more margin, the limit will be increased from 140 percent per day to 225 percent per day with resultant increases in SGT System exhaust flow rate show in Tables 1 and 2.

Due to the assumed increase in release rate, the dose consequences will increase for the Exclusion Area Boundary (EAB), control room operator, and Low Population Zone (LPZ) but remain below the regulatory limit specified in 10 CFR 50.67; the doses to the control room operator and LPZ will decrease as a result of aggregate impacts (see Section 3.7 of this Enclosure). As stated in the FSAR Section 6.5.1.1.1, the only DBAs that the SGT System is required to mitigate are the DBA LOCA (FSAR Section 15.6.5) and Fuel and Equipment

Enclosure 1 to PLA-7823 Page 8 of 19 Handling Accident (FSAR Section 15.7.4). The Main Steam Line Break Outside Containment and the Control Rod Drop Accident do not credit SGT System operation for dose contributions from their respective activity release pathways. The Fuel and Equipment Handling Accident assumes a non-mechanistic activity release over a two hour period. So, even though the SGT System is credited for this accident, the SGT System exhaust flow rate is not representative of the physical system and a specific SGT System exhaust flow rate that correlates to the actual system performance is not assumed in the analysis. Therefore, the only design basis dose analysis that is impacted is the DBA LOCA analysis.

The change is within the capacity of the SGT System so there is no expected impact to SGT System equipment due to the increased flow rate. The other impact of the proposed change is the ability of the SGT System to drawdown the reactor building to a vacuum of 0.25 in. wg post-accident. Per SR 3.6.4.1.4, the secondary containment 0.25 in. wg vacuum must be re-established within five minutes, which bounds the 10 minute drawdown assumed in the dose analysis. The drawdown time will continue to be validated through SR 3.6.4.1.4. The drawdown time is an assumed value in the DBA LOCA dose consequence analysis and is not proposed to be changed in this amendment request.

The Realistic LOCA analysis, which is bounded by the DBA LOCA results, also utilizes the current 140 percent per day inleakage value. The Realistic LOCA analysis has been re-performed using the 225 percent per day inleakage value and the results will be implemented pursuant to 10 CFR 50.59 following the approval of this submittal.

3.4 Control Room Habitability Envelope Unfiltered Inleakage Under LOCA conditions, habitability for the Control Structure is maintained by the CREOAS System. This system provides habitability zone isolation and a positive pressure for the CRHE.

The CRHE is defined for SSES as six separate floors of the control building (refer to ).

Habitability systems are designed to ensure habitability inside the control structure pressurization envelope during all normal and abnormal station operating conditions including the post-LOCA requirements, pursuant to General Design Criteria (GDC) 19 of 10 CFR 50, Appendix A, and 10 CFR 50.67.

The 10 CFR 50.67 dose limit is 5 Rem Total Effective Dose Equivalent (TEDE) to the control room operators. The control structure unfiltered inleakage is leakage into the control structure habitability boundary that bypasses the emergency filtration system (CREOAS). The DBA LOCA analysis assumes a value of control structure unfiltered inleakage that is controlled by the TS 5.5.14 Control Room Envelope Habitability Program and verified by SR 3.7.3.4. This value is controlled by the program, so there are no required TS changes to support the increase in

Enclosure 1 to PLA-7823 Page 9 of 19 CRHE unfiltered inleakage. The control structure unfiltered inleakage only impacts the control room operator dose and does not affect the EAB and LPZ doses.

The proposed change will increase the allowable unidentified unfiltered inleakage from 500 cfm to 600 cfm. This change is proposed in order to provide additional margin for the tracer gas inleakage tests performed at SSES per SR 3.7.3.4 as required by TS 5.5.14. This change is necessary due to the unique nature of the SSES CRHE. The envelope at SSES encompasses multiple floor elevations in the control structure. In order to pressurize a boundary of this size, a substantial amount of outside air is required (5810 cfm). Substantial error is introduced into the testing due to measurement of this flow rate and also due to maintaining a uniform concentration in the various rooms on different elevations. In the last tracer gas testing performed in 2017, uncertainty associated with the A train was +/-326 cfm. This is a substantial portion of the available limit. To provide more margin, the limit will be increased from 500 cfm to 600 cfm.

The unfiltered control structure inleakage testing acceptance criterion with CREOAS in operation (emergency mode) will be increased to 600 cfm. The DBA LOCA design analysis will be updated to reflect this increase. The only other analysis that relies on CREOAS System actuation is the Equipment and Fuel Handling Accident. This analysis has been re-performed using 600 cfm and the results will be implemented pursuant to 10 CFR 50.59 following the approval of this submittal.

The Realistic LOCA analysis, which is bounded by the DBA LOCA analysis, also utilizes the current 500 cfm CRHE unfiltered inleakage value. The Realistic LOCA analysis has been re-performed utilizing the 600 cfm CRHE unfiltered inleakage value and the results will be implemented pursuant to 10 CFR 50.59 following the approval of this submittal.

3.5 Control Room Habitability Envelope Continuous Occupancy Locations The CRHE is designed with adequate radiation protection to permit access and occupancy of the control room under accident conditions without personnel receiving radiation exposures in excess of specified values. Although all areas of the control structure envelope are designed for habitability following a DBA LOCA, not all areas inside the envelope require continuous occupancy. The current DBA LOCA analysis assumes continuous occupancy in the following locations (refer to Enclosure 7):

Control Structure Elevation 729-1 (All areas)

Control Structure Elevation 741'-1" (All areas)

Computer Room (Room C-202) at Elevation 698'-0"

Enclosure 1 to PLA-7823 Page 10 of 19 Susquehannas AST submittal (approved in Reference 1) states that Elevations 698 (Computer Room), 729-1 (Control Room), and 741-1 (TSC) are the only areas of the CRHE that require personnel to meet the occupancy requirements of RG 1.183, Section 4.2.6 during a DBA LOCA.

Other areas of the CRHE require significantly less occupancy. The current calculated CRHE dose (TEDE) for areas assumed to be continuously occupied post-accident are displayed in Table 3.

Table 3: Current Dose (including Shine) for Areas Assumed to be Continuously Occupied Post-LOCA Dose Plant Area (Rem TEDE)

Control Structure Elevation 729-1 4.35

- All areas except Rooms C-401 & C-402, includes Main Control Room Control Structure Elevation 741-1 4.35

- All areas except Rooms C-413 and C-414, includes TSC Control Structure Elevations 729-1 and 741-1 4.69

- All remaining areas (Rooms C-401 (STA Office), C-402 (Backup OSC),

C-413 (Electrical Equipment Room) and C-414 (NRC Conference Room))

Control Structure Elevation 698-0 4.35

- Computer Room (Room C-202)

The proposed change reduces the continuous occupancy assumption to the following rooms following a DBA LOCA:

Main Control Room (Room C-409), Elevation 729-1

Technical Support Center (Room C-410), Elevation 741-1

Computer Room (Room C-202), Elevation 698-0 Elevation 729-1 contains the Main Control Room (Room C-409), the Shift Technical Advisor (STA) Office (Room C-401), the Backup OSC (Room C-402), and other ancillary rooms.

Elevation 741-1 contains the TSC (Room C-410), an electrical equipment room (Room C-413) and the NRC conference room (Room C-414). All areas on elevations 729-1 and 741-1 are currently assumed to be continuously occupied post-accident. Based on the locations of the piping sources inside the reactor building, the maximum dose rate inside these areas occurs at the closest location to the 14 GBB-101 core spray line. The shine dose rate from this contained

Enclosure 1 to PLA-7823 Page 11 of 19 source for corresponding locations in the north and south ends of these areas is the same due to the same source locations in both the Unit 1 and Unit 2 reactor buildings.

On elevation 729-1, the STA Office (Room C-401) and the Backup OSC (Room C-402) are directly opposite the location of 14 GBB-101. On elevation 741-1, an electrical equipment room (Room C-413) and the NRC conference room (Room C-414) are also directly opposite the location of 14 GBB-101. As a result of the location of the contained source piping, the Electrical Equipment Room (C-413) has the limiting dose (4.69 Rem TEDE).

It was previously acknowledged that assuming continuous occupancy in the ancillary rooms on Elevations 729-1 and 741-1 was a conservative assumption. Continuous occupancy of rooms other than the Control Room, TSC, and Computer Room is not required for safe plant operation or for execution of the Emergency Plan. Therefore, access to the additional rooms on Elevations 729-1 and 741-1 can be restricted if needed based on radiation monitoring and the assumption of continuous occupancy will be removed from the DBA LOCA analysis.

3.6 Analysis Code (RADTRAD) Version As described in Section 1.1 of Reference 6, Alion has revised RADTRAD from Version 3.03 to Version 3.10 (Reference 7) to correct errors and to add enhancements. RADTRAD Version 3.03 was used in Susquehannas AST amendment and the specific version of the code was specifically referenced in the Safety Evaluation attached to Reference 1.

RADTRAD Version 3.10 is a level 2 software package controlled in accordance with Susquehannas Software Quality Assurance Program. Verification and validation calculations were performed for Susquehanna and demonstrated RADTRAD Version 3.10 is slightly more conservative than RADTRAD Version 3.03.

3.7 Resultant Dose Consequences RG 1.183 (Reference 4) provides guidance for implementation of 10 CFR 50.67. This includes assumptions and methods that are acceptable to the NRC for performing design basis radiological analyses using an AST. RG 1.183, Table 6, provides DBA LOCA dose limits at the EAB (worst 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ) and LPZ of 25 Rem TEDE. The control room dose limit is 5 Rem TEDE per 10 CFR 50.67.

The proposed changes result in dose consequences that would remain within the regulatory limits. The aggregate of effects from implementing the evaluated changes in Sections 3.1 to 3.6 will decrease the Control Room and LPZ doses and will increase the EAB dose. The increase to the worst case two hour EAB dose is within 10 percent of the available margin to the regulatory limit. Consequently, this proposed change represents only a minimal increase in consequences of the previously evaluated conditions in the FSAR. The LOCA Control Room operator dose is

Enclosure 1 to PLA-7823 Page 12 of 19 below the 5 Rem TEDE regulatory limit and the offsite doses are well below the 25 Rem TEDE regulatory limit.

4. Regulatory Evaluation 4.1 Applicable Regulatory Requirements/Criteria Title 10 Code of Federal Regulations (10 CFR) 50.67 10 CFR 50.67 requires those licensees with an approved alternative source term to ensure, with reasonable assurance that:

(i) An individual located at any point on the boundary of the exclusion area for any two-hour period following the onset of the postulated fission product release, would not receive a radiation dose in excess of 0.25 Sv (25 Rem) total effective dose equivalent (TEDE).

(ii) An individual located at any point on the outer boundary of the low population zone, who is exposed to the radioactive cloud resulting from the postulated fission product release (during the entire period of its passage), would not receive a radiation dose in excess of 0.25 Sv (25 Rem) total effective dose equivalent (TEDE).

(iii) Adequate radiation protection is provided to permit access to and occupancy of the control room under accident conditions without personnel receiving radiation exposures in excess of 0.05 Sv (5 Rem) total effective dose equivalent (TEDE) for the duration of the accident.

Conclusion 10 CFR 50.67 establishes the radiological dose limits for accident conditions.

10 CFR 50.67(b)(2) requires that licensees maintain dose to specific groups of individuals below 5 Rem or 25 Rem, depending on proximity to the accident. As demonstrated in Table 4, each of

Enclosure 1 to PLA-7823 Page 13 of 19 the radiological dose limits for a LOCA will continue to be met upon revising the DBA LOCA analysis in the manner described herein. Therefore, 10 CFR 50.67 will continue to be met.

10 CFR 50.36(c)(3)

Surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that the facility operation will be within safety limits, and that the limiting conditions for operation will be met.

Conclusion 10 CFR 50.36 sets the regulatory requirements for the content of TS. 10 CFR 50.36(c)(3) requires, in part, that the TS contain SRs, and that the SRs ensure plant safety limits and limiting conditions of operation are met. The proposed change would modify the acceptance criteria for demonstrating an SR has been met which are not specified by the regulation. Therefore, 10 CFR 50.36(c)(3) will continue to be met.

10 CFR 50.36(c)(5)

Administrative controls are the provisions relating to organization and management, procedures, recordkeeping, review and audit, and reporting necessary to assure operation of the facility in a safe manner.

Conclusions 10 CFR 50.36 sets the regulatory requirements for the content of TS. 10 CFR 50.36(c)(5) requires, in part, that the TS contain administrative controls to ensure that the overall organization and management of a nuclear power plant assures safe operation of the plant. The proposed change would modify the scope of the Primary Coolant Sources Outside Containment program, the content of which is not specified by the regulation. Therefore, 10 CFR 50.36(c)(5) will continue to be met.

10 CFR 50.59(c)(2)

A licensee shall obtain a license amendment pursuant to 10 CFR 50.90 prior to implementing a proposed change, test, or experiment if the change, test, or experiment would. . . (viii) Result in a departure from a method of evaluation described in the FSAR (as updated) used in establishing the design bases or in the safety analyses.

Enclosure 1 to PLA-7823 Page 14 of 19 Conclusion Susquehanna has determined that the proposed changes to the LOCA Dose Analysis constitute a departure from a method of evaluation described in the FSAR used in establishing the design bases or in the safety analyses. As such, Susquehanna is requesting a license amendment pursuant to 10 CFR 50.90 prior to implementing the proposed change.

General Design Criteria During the applicable period of this proposed license amendment, SSES will maintain the ability to meet the applicable GDC as outlined in 10 CFR 50, Appendix A. The applicable GDC are:

GDC-5, Sharing of Structures, Systems, and Components Structures, systems, and components important to safety shall not be shared among nuclear power units unless it can be shown that such sharing will not significantly impair their ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units.

GDC-19, Control Room A control room shall be provided from which actions can be taken to operate the nuclear power unit safely under normal conditions and to maintain it in a safe condition under accident conditions, including loss-of-coolant accidents. Adequate radiation protection shall be provided to permit access and occupancy of the control room under accident conditions without personnel receiving radiation exposures in excess of 5 Rem whole body, or its equivalent to any part of the body, for the duration of the accident. . . holders of operating licenses using an alternative source term under § 50.67, shall meet the requirements of this criterion, except that with regard to control room access and occupancy, adequate radiation protection shall be provided to ensure that radiation exposures shall not exceed 0.05 Sv (5 rem) total effective dose equivalent (TEDE) as defined in § 50.2 for the duration of the accident.

Conclusion The proposed change to the LOCA dose analysis does not result in any permanent changes to installed structures, systems, or components. Rather, the proposed change modifies the manner by which dose calculations are performed by accounting for new isotopic inventories and adjusting assumptions to more realistically model a LOCA at SSES. As demonstrated in Section 3 of this enclosure, all changes to the LOCA analysis are consistent with the appropriate regulatory guidance and all regulatory limits regarding total dose continue to be met. Therefore,

Enclosure 1 to PLA-7823 Page 15 of 19 the criteria above and as listed in 10 CFR 50, Appendix A, and the SSES FSAR continue to be met.

4.2 Precedent The NRC routinely approves license amendments which make changes to dose consequence analyses of records. Recently, the NRC issued an amendment to Virginia Electric and Power Company for the Surry Power Station which utilized new analysis codes, updated atmospheric dispersion factors, and made other changes (Reference 8). The Surry amendment approved in Reference 8 did not utilize TRITON/ORIGEN-ARP for generation of the source term. However, the NRC has approved a revision to Certificate of Compliance No. 9302 for TN Americas which utilized a source term calculated using TRITON/ORIGEN-ARP in SCALE 6.0 (Reference 9) and has issued an exemption to Entergy which utilized ORIGEN-ARP in an Exemption Request for the Pilgrim Nuclear Power Station to support decommissioning (Reference 10).

Additionally, the NRC issued an amendment to Indiana Michigan Power Company for the DC Cook Nuclear Power Plant regarding implementation of AST (Reference 11). In its application for this amendment, Indiana Michigan Power Company stated that they utilized RADTRAD Version 3.10 in its analyses.

While none of these amendments are directly applicable to Susquehannas request, they do demonstrate the acceptability of updating AST analyses using TRITON/ORIGEN-ARP and RADTRAD Version 3.10.

4.3 No Significant Hazards Consideration Analysis Pursuant to 10 CFR 50.90, Susquehanna Nuclear, LLC (Susquehanna), is submitting a request for an amendment to the Updated Final Safety Analysis Report (FSAR) and Technical Specifications (TS) for the Susquehanna Steam Electric Station (SSES), Units 1 and 2, Facility Operating License numbers NPF-14 and NPF-22. The proposed amendment would modify the Current Licensing Basis (CLB) for the Design Basis Accident (DBA) Loss of Coolant Accident (LOCA) analysis described in the SSES FSAR, as previously reviewed by the NRC. The proposed changes would utilize an updated version of the ORIGEN code, introduce a new source term to account for the introduction of ATRIUM 11 fuel, use new inputs/assumptions that decrease the assumed Emergency Safety Feature (ESF) leakage into secondary containment, increase the assumed maximum allowable Standby Gas Treatment (SGT) System exhaust flow rate from secondary containment, increase the allowed control structure unfiltered inleakage that is assumed in the DBA LOCA dose analysis. As a result, the proposed amendment would modify TS 5.5.2, Primary Coolant Sources Outside Containment, and the TS Bases for TS 3.6.4.1, Secondary Containment.

Susquehanna has evaluated the proposed amendment against the standards in 10 CFR 50.92 and has determined that the operation of SSES in accordance with the proposed amendment presents

Enclosure 1 to PLA-7823 Page 16 of 19 no significant hazards. Susquehannas evaluation against each of the criteria in 10 CFR 50.92 follows.

1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?

Response: No The proposed change would modify inputs and assumptions to the DBA LOCA analysis to account for a new fuel type while more realistically modeling the impacts of a LOCA at SSES. The proposed change is considered to be a departure from a method of evaluation described in the FSAR, but it does not modify any structures, systems, or components (SSCs) installed at SSES. The proposed change does result in a higher Exclusion Area Boundary (EAB) dose calculated as a result of a postulated LOCA. The increased dose does not affect any initiator or precursor of any accident previously evaluated. Thus, the proposed change does not involve a significant increase in the probability of an accident previously evaluated. Further, the increase in post-LOCA radiological dose remains within the limits of 10 CFR 50.67 and 10 CFR 50, Appendix A, Criterion 19. As such, the proposed change also does not involve a significant increase in the consequences of an accident previously evaluated.

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No The proposed change would modify inputs and assumptions to the DBA LOCA analysis to account for a new fuel type while more realistically modeling the impacts of a LOCA at SSES. The proposed change does not alter the design function or operation of any SSCs installed at SSES. The proposed change is considered a departure from a method of evaluation described in the FSAR and it does result in new or different assumptions into the DBA LOCA analysis, but all assumptions are within the capabilities of installed SSCs or are relaxations to existing assumptions that are assumed while still demonstrating the post-LOCA radiological dose remains within the limits of 10 CFR 50.67 and 10 CFR 50, Appendix A, Criterion 19. The proposed change does not introduce any new modes of plant operation. As such, no new failure modes are introduced.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

Enclosure 1 to PLA-7823 Page 17 of 19

3. Does the proposed change involve a significant reduction in a margin of safety?

Response: No The proposed change is considered a departure from a method of evaluation described in the FSAR. But, the calculations continue to be performed in accordance with the requirements of 10 CFR 50.67 and Regulatory Guide 1.183. The margin of safety is considered to be that provided by meeting the applicable regulatory limits. The proposed changes do result in an increase to post-LOCA radiological dose at the EAB. However, the post-LOCA dose remains within the regulatory limits of 10 CFR 50.67 and 10 CFR 50, Appendix A, Criterion 19.

Therefore, the proposed change does not involve a significant reduction in a margin of safety.

Based on the above evaluation, Susquehanna concludes that the proposed amendment does not involve a significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of no significant hazards consideration is justified.

4.4 Conclusions In conclusion, based on the considerations discussed above, (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commissions regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.

5. Environmental Consideration Susquehanna has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure.

Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

Rev. 15 Secondary Containment B 3.6.4.1 BASES SURVEILLANCE SR 3.6.4.1.4 and SR 3.6.4.1.5 REQUIREMENTS (continued) The SGT System exhausts the secondary containment atmosphere to the environment through appropriate treatment equipment. To ensure that all fission products are treated, SR 3.6.4.1.4 verifies that the SGT System will rapidly establish and maintain a pressure in the secondary containment that is less than the pressure external to the secondary containment boundary.

This is confirmed by demonstrating that one SGT subsystem will draw down the secondary containment to 0.25 inches of vacuum water gauge in less than or equal to the maximum time allowed. This cannot be accomplished if the secondary containment boundary is not intact. SR 3.6.4.1.5 demonstrates that one SGT subsystem can maintain 0.25 inches of vacuum water gauge for at least 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months at less than or equal to the maximum flow rate permitted for the secondary containment configuration that is operable. The 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months test period allows secondary containment to be in thermal equilibrium at steady state conditions. As noted, both SR 3.6.4.1.4 and SR 3.6.4.1.5 acceptance limits are dependent upon the secondary containment configuration when testing is being performed. The acceptance criteria for the SRs based on secondary containment configuration is defined as follows:

SECONDARY MAXIMUM DRAWDOWN TIME (SEC) MAXIMUM FLOW RATE (CFM)

CONTAINMENT (SR 3.6.4.1.4 (SR 3.6.4.1.5 TEST CONFIGURATION ACCEPTANCE CRITERIA) ACCEPTANCE CRITERIA)

Secondary Containment).

Only one of the above listed configurations needs to be tested to confirm secondary containment OPERABILITY.

The secondary containment testing configurations are discussed in further detail to ensure the appropriate configurations are tested. Three zone testing (Zones, I, II and III aligned to the recirculation plenum) should be performed with the Railroad Bay aligned to secondary containment and another test with the Railroad Bay not aligned to secondary containment.

Each test should be performed with each division on a STAGGERED TEST BASIS.

Two zone testing (Zones II and III aligned to the recirculation plenum) should be performed with the Railroad Bay aligned to secondary containment and another test with the Railroad Bay not aligned to secondary containment.

Each test should be performed with each division on a STAGGERED TEST BASIS. The normal operating fans of the non-tested HVAC zone (Zone I fans 1V202A&B, 1V205A&B and 1V206A&B) should not be in operation.

Additionally, a controlled opening of adequate size should be maintained in Zone I Secondary Containment during testing to assure that atmospheric conditions are maintained in that zone.
