NL-22-0757 Assessment of Amendments 317 and 262 Impact on HNP TSTF-505 License Amendment Request E - 1
1.0 INTRODUCTION
On October 26, 2021 [ADAMS Accession Number ML21300A153], Southern Nuclear Operating Company (SNC) requested amendments to Edwin I. Hatch Nuclear Plant (HNP), Units 1 and 2 renewed facility operating licenses (RFOLs) DPR-57 and NPF-5, respectively. The proposed amendment requested U.S. Nuclear Regulatory Commission (NRC) approval to modify Technical Specifications (TS) requirements to permit the use of Risk Informed Completion Times in accordance with TSTF-505, Revision 2, "Provide Risk-Informed Extended Completion Times - RITSTF Initiative 4b" [ML18183A493]. The LAR impacted several TS sections, including TS 3.6.1.3, Primary Containment Isolation Valves.
On December 6, 2021, subsequent to the submittal of the HNP TSTF-505 license amendment request (LAR), SNC submitted a LAR to adopt certain aspects of TSTF-207 [ML21340A255].
On September 2, 2022, the NRC issued Amendments 317 and 262 to the HNP Units 1 and 2 RFOLs, respectively, approving SNCs HNP TSTF-207 LAR. Amendments 317 and 262 include changes to some of the same pages in TS 3.6.1.3 as SNCs TSTF-505 LAR.
2.0 DESCRIPTION
OF CHANGE AND ASSESSMENT OF IMPACT The issuance of HNP RFOL Amendments 317 and 262 included issuance of revised TS pages 3.6-7 through 3.6-12 (impacts TS 3.6.1.3 Conditions A through D and Required Action D.1 Completion Time). The Hatch TSTF-505 LAR included changes to TS pages 3.6-7 through 3.6-9 (impacts Condition A Required Actions and Completion Times and Required Action Completion Time C.2), thus there is overlap in the affected pages. Table 1 provides descriptions of the changes and assess the impact Amendments 317 and 262 have on SNCs HNP TSTF-505 LAR.
NL-22-0757 Assessment of Amendments 317 and 262 Impact on HNP TSTF-505 License Amendment Request E - 2 Table 1: Descriptions of Changes and Assessment of Impact (Sheet 1 of 5)
TS 3.6.1.3 Condition (1)(2)
Amendment 317 and 262 Changes (3)
HNP TSTF-505 LAR Proposed Changes (3)
Assessment of Impact to HNP TSTF-505 LAR A
Revised Condition A Note as follows:
Only applicable to penetration flow paths with two or more PCIVs.
Adds following Note to Required Action A.1:
Not applicable to main steam line.
The addition of or more to the Note of TS 3.6.1.3, Condition A, clarifies that the Condition applies to penetration flow paths with more than two PCIVs. This was an administrative change aligning the HNP TS with TSTF-207-A, Revision 5 as implemented in the Boiling Water Reactor (BWR) Owners Group Standard Technical Specifications (STS), NUREG-1433. Due to the administrative nature of this change, there is no impact to the proposed note that the HNP TSTF-505 LAR adds to Required Action A.1 (which is also an administrative change itself as described in Attachment 1, Section 2.3 of the HNP TSTF-505 LAR [ML21300A153]).
Revised Condition A as follows:
One or more penetration flow paths with one PCIV inoperable except due to leakage not within limit for reasons other than Condition D.
Revises Required Action A.1 Completion Time as follows:
4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> except for main steam line OR In accordance with the Risk Informed Completion Time Program AND 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> for main steam line Rewording the exception to refer to reasons other than TS 3.6.1.3 Condition D is an administrative/equivalent change since TS 3.6.1.3 Condition D and TS 3.6.1.1 have required actions for leakage not within limits. Due to the administrative nature of this change, other than changes to background text in the TS markups, there is no impact to the proposed change that the HNP TSTF-505 LAR makes to Required Action A.1 (which is also an administrative change itself as described in, Section 2.3 of the HNP TSTF-505 LAR).

Amendment 317 and 262 Changes (3)
HNP TSTF-505 LAR Proposed Changes (3)
Assessment of Impact to HNP TSTF-505 LAR A (contd)
Adds new Required Action A.2 as follows:
NOTE---------------
Only applicable to main steam line.
Isolate the affected penetration flow path by use of at least one closed and de-activated automatic valve, closed manual valve, blind flange, or check valve with flow through the valve secured.
The assessment of Required Action A.1 in previous row also applies to the addition of a new Required Action A.2.
Adds new Required Action A.2 Completion Time as follows:
8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> OR In accordance with the Risk Informed Completion Time Program The assessment of Required Action A.1 in previous row also applies to the addition of a Completion Time for new Required Action A.2.

Amendment 317 and 262 Changes (3)
HNP TSTF-505 LAR Proposed Changes (3)
Assessment of Impact to HNP TSTF-505 LAR A (contd)
Renumbers Required Action A.2 to A.3 as follows:
A.23 This is an administrative change due to making Required Action A.1 two separate Required Actions, A.1 and A.2. Amendments 317 and 262 have no impact on this change.
Revises first part of new Required Action A.3 Completion Time as follows:
Once per 31 days following isolation for isolation devices outside primary containment The HNP TSTF-505 LAR adds following isolation in accordance with TSTF-505-A, Revision 2 to account for the time change caused by RICT implementation. The Amendment 317 and 262 change to Condition A have no impact on this change.
B Revised Condition B Note as follows:
Only applicable to penetration flow paths with two or more PCIVs.
The addition of or more to the Note of TS 3.6.1.3, Condition B, clarifies that the Condition applies to penetration flow paths with more than two PCIVs. This was an administrative change aligning the HNP TS with TSTF-207-A, Revision 5 as implemented in the BWR Owners Group STS, NUREG-1433. Due to the administrative nature of this change, there would be no change in application of the HNP TSTF-505 LAR proposed changes, and there is no impact to the HNP TSTF-505 LAR other than changes to background information in the TS markups.
NL-22-0757 Assessment of Amendments 317 and 262 Impact on HNP TSTF-505 License Amendment Request E - 5 Table 1: Descriptions of Changes and Assessment of Impact (Sheet 4 of 5)
TS 3.6.1.3 Condition (1)(2)
Amendment 317 and 262 Changes (3)
HNP TSTF-505 LAR Proposed Changes (3)
Assessment of Impact to HNP TSTF-505 LAR B (contd)
Changed Condition B as follows:
One or more penetration flow paths with two or more PCIVs inoperable except due to leakage not within limit for reasons other than Condition D.
See discussion of Condition A change above. Additionally, Condition B is not involved in the HNP TSTF-505 LAR, so there is no impact to the HNP TSTF-505 LAR other than changes to background text in the TS markups.
C Changed Condition C as follows:
One or more penetration flow paths with one PCIV inoperable except due to leakage not within limit for reasons other than Condition D.
Revises Required Action C.2 Completion Time as follows:
Once per 31 days following isolation The discussion of the Condition A change above also applies to Condition C.
The HNP TSTF-505 LAR adds following isolation in accordance with TSTF-505-A, Revision 2 to account for the time change caused by RICT implementation. The Amendment 317 and 262 changes to Condition C have no impact on this change.
D Changed Condition D as follows:
One or more penetration flow paths with leakage secondary containment bypass leakage rate, MSIV leakage rate, or EFCV leakage rate not within limit.
This change specifies the individual types of penetration flow paths to which the Condition applies. The HNP TSTF-505 LAR does not propose applying Risk Informed Completion Time to the Condition D Required Action. Therefore, there is no impact to the HNP TSTF-505 LAR aside from changes to background text in the TS markups.
