Nuclear Regulatory Commission Attention: Document Control Desk Washington, DC 20555-0001 South Texas Project Units 1 and 2 Docket Nos. STN 50-498, STN 50-499 Amendment to the South Texas Project License Renewal Application in Response to LR-ISG-201 1-01 (TAC Nos. ME4936 and ME4937)

References:

1. STPNOC letter dated October 25, 2010, from G. T. Powell to NRC Document Control Desk, "License Renewal Application" (NOC-AE-1 0002607)

(ML103010257)

2. Final License Renewal Interim Staff Guidance LR-ISG-2011-01, "Aging Management of Stainless Steel Structures and Components in Treated Borated Water" (ML12034A047)

By Reference 1, STP Nuclear Operating Company (STPNOC) submitted a License Renewal Application (LRA) for South Texas Project (STP) Units 1 and 2. Reference 2 provides guidance as to one acceptable approach to managing the effects of aging during the period of extended operation of stainless steel structures and components exposed to treated borated water within the scope of the License Renewal Rule. Reference 2 is directed to current applicants for license renewal.

The Nuclear Regulatory Commission staff determined that boron should not be credited as a corrosion inhibitor for stainless steel components in treated borated water. The recommendations in the License Renewal Standard Review Plan and the Generic Aging Lessons Learned Report is revised by LR-ISG-201 1-01 to include the following additional aging management activities to align the guidance for treated borated water with that for treated water:

Add the One-Time Inspection program to verify the effectiveness of the Water Chemistry program to manage loss of material due to pitting and crevice corrosion and cracking due to stress corrosion cracking in treated borated water. The revised guidance applies to stainless steel structures and components exposed to treated borated water environments that are not actively controlled to oxygen levels less than 5 ppb.

NOC-AE-12002883 Page 2

  • Add reduction of heat transfer due to fouling as an aging effect for stainless steel heat exchanger tubes exposed to treated borated water, and manage this aging effect with the Water Chemistry and One-Time Inspection programs.

A review of the STPNOC LRA determined the following:

" The application provides for a One-Time Inspection program to verify the effectiveness of the Water Chemistry program to manage loss of material due to pitting and crevice corrosion and cracking due to stress corrosion cracking in treated borated water.

  • Changes are required to address the aging effect of reduction of heat transfer for stainless steel heat exchangers. Additionally, during this review all heat exchangers were reviewed regardless of material. LRA Tables 2.3.3-6, 2.3.3-17, 2.3.3-19, 3.3.2-6, 3.3.2-17 and 3.3.2-19 are revised to add the effect of reduction of heat transfer for stainless steel and copper alloy heat exchangers.

The enclosure to this letter provides a revision to the STP LRA depicted by line-in/line-out annotations.

There are no regulatory commitments in this letter.

Should you have any questions regarding this letter, please contact either Arden Aldridge, STP License Renewal Project Lead, at (361) 972-8243 or Ken Taplett, STP License Renewal Project regulatory point-of-contact, at (361) 972-8416.

I declare under penalty of perjury that the foregoing is true and correct.

Notes for Table 3.3.2-6:

Standard Notes:

A Consistent with NUREG-1 801 item for component, material, environment, and aging effect. AMP is consistent with NUREG-1801 AMP.

B Consistent with NUREG-1801 item for component, material, environment, and aging effect. AMP takes some exceptions to NUREG-1801 AMP.

D Component is different, but consistent with NUREG-1801 item for material, environment, and aging effect. AMP takes some exceptions to NUREG-1801 AMP.

E Consistent with NUREG-1 801 for material, environment, and aging effect, but a different aging management program is credited or NUREG-1801 identifies a plant-specific aging management program.

F Material not in NUREG-1801 for this component.

G Environment not in NUREG-1801 for this component and material.

H Aging effect not in NUREG-1801 for this component, material and environment combination.

Plant Specific Notes:

1 Loss of preload is conservatively considered to be applicable for all closure bolting.

2 The Water Chemistry program (B2.1.2) and the One-Time Inspection program (B2.1.16) manage loss of material due to pitting and crevice corrosion and cracking due to stress corrosion cracking. The One-Time Inspection program (B2.1.16) includes selected components at susceptible locations 3 Non-inhibited copper alloy >15% zinc SSCs with surfaces exposed to ventilation atmosphere (internal) or plant indoor air (internal) are subject to wetting due to condensation and thus are subject to loss of material due to selective leaching.

4 The reduction of heat transfer aaina effect is not identified in NUREG-1801 for this component, material, and environment combination.

Reduction of heat transfer is not expected in heat exchangqers with reactor coolant or treated borated water environments as long as water chemistry is maintained. Reduction of heat transfer is managed with Water Chemistry (B2.1.2) and One-Time Inspection (B2.1.16).
